vif-devel Mailing List for VIF (Page 5)

Hello

I've released version 0.6.0 of VIF. I've expanded the framework so that it
can handle nested queries too. With that, the list of discussion groups,
using nested queries, become much more informative. However, with this
improvement the applicaton requires Version 4.1.0 of the MySQL database.

Here's the list of changes:

VIF Framework 0.9.0
- Added handling of nested queries to Domain Object Framework.
- Implemented creation of script links in html head (in analogy to CSS
links).
- Updated domain object framework documentation.

VIF Application 0.6.0
- GroupList in Forum shows the number of participants registered actually.
This feature is the result of the new nested query feature of the Domain
Object Framework.
- Made discussion groups workflow aware: State changes are triggered
automatically or by group administrators. The participants are notified
about state changes of groups.
- Redesigned display of question and completion view.
- Improved formatting of messages.
- Precheck before view to create new contribution is displayed: Group has to
be active and actor has to be registered.

Regards,
Benno

Hello

Features added to the application:
- Added task to scroll the lists over multiple pages.
- Added automated role management to group admin and registering tasks.

Bugs fixed in the application:
- Bug fixed in stylesheet for creation of completion.

Features added to the Framework.
- Made Context Serializable, thus adding Tomcat restart persistence to the
framework.
- Added possibility to disable connection pooling.

Additionally I've added a Walktrough example to the documentation (see
http://vif.sourceforge.net/WalkThrough.html).

Regards,
Benno

A note about naming.

I renamed the table tblContribution (and all associated tables) to
tblCompletion.

This makes it possible to use the term 'Contribution' in a consistant way
for all potentially publishable content, i.e. questions, completions,
biographic and bibliographic information.

Contributions are stored in the tables tblQuestion, tblCompletion, tblPerson
and tblText (and their histories).

The term 'Completion' then is used for information related and added to
questions, e.g. potential answers. Completions are stored in tblCompletion.

Regards,
Benno

Hello

I've released Release 0.5.0 of the application VIF.

Changes in the application:
- Refactored datamodel and domain objects to avoid potential
misunderstanding: Renamed tblContribution to tblCompletion and replaced
'contribution' with 'completion' throughout the whole application.
- Made question and completion object workflow aware.
- Made publication of questions and completions by administrators steps in
the VIF workflow.
- Made list of questions for administrators contingent to their role, i.e.
the Administrator views more then the GroupAdmin.
- Implemented use cases 3 (posting of forum contributions), 4 (review of
forum contributions) and 5 (revision of a rejected forum contributions).
- Added script to create tblPerson and the corresponding domain object and
it's home.

Changes in the framework:
- Refactored KeyObject, thus making KeyObjects involved and recursive. With
this, it is possible to create grouped SQL WHERE statements, e.g. "... WHERE
groupid = 43 AND ((memberid = 22 AND isauthor = 1) OR state = 3)"

Regards,
Benno

I've checked in and released the workflow package that the application VIF
will use.

The VIF workflow framework provides basic workflow functionality. It is
designed to support the management of all sorts of publishable content.

The VIF workflow framework package is the Java implementation of the Python
workflow module ‘itools’ created by Juan David Ibáñez Palomar
(jd...@it...).

The package consists of the jar file containing the compiled framework and a
jar file containing the source code and a unit test. In addition the package
includes documentation describing the use of the workflow framework (see
http://vif.sourceforge.net/WorkflowFramework.pdf).

The workflow package is integrated in the VIF framework, but the project VIF
made the workflow package separately downloadable (see
https://sourceforge.net/projects/vif/) for use in other Java frameworks and
applications.

Benno

Dear Aparup

I send you the files with my remarks added.

table_tblPerson.sql:
I made the primary key auto incrementing, changed the field type of
dtMutation to timestamp, added the index idxPerson_01 (sName, sFirstName),
removed the constraint 'not null' except for the fields name and firstname
and changed a little bit the field widths.

You can find the remarks concerning the Java code in the classes attached.
I've added PersonImplTest.java, a JUnit testcase testing the classes you
created.

I'll check in the reviewed code in the next days.

Regards,
Benno

Dear Benno,

I started the tblPerson Feature yesterday:
Following are the action items i taken:
i) Created a Table for tblPerson.
ii)Created the Person, PersonHome DOM
and PersonImpl and PersonHomeImpl.

I am attaching the files along with, plz go through them in your spare
time and if possible give your inline comments where ever required, this
will help me in better undersatnding of the vif framework.

Nextly i have decided to go ahead and code for the Person*Task files and
after that the required views.

One more thing which i have noticed while coding for the models, we can
generate a greate piece of code for them, as they follow a fixed
teamplate.
May be we can take this, after we are done with the great deal of the
whole application.

Let me know your remarks.

Aparup

Hello

I've released Release 0.4.1 of the application VIF.

The changes in this release are intended to make deployment easier.

Changes in the application:
- Added the concrete method getSysName() to the application's servlet thus
providing the application's name of the configuration file.

Changes in the framework:
- Added setters to VSys making the application's configuration object able
to read the application's configurations from a properties file having any
name residing at any place.
- Overwrote the init() method in AbstractRequestHandler (the framework's
servlet) to initialize the application's configuration with the
application's servlet context and the name of the configuration file.
- Added the abstract method getSysName() all classes extending the
application's servlet have to implement. This method returns the name of the
application's configuration file.

Regards,
Benno

Benno

Dear Swati

> Ein Super User kann nur f|r eine neue Installation
> erzeugt werden.
The message above is german and says:
"It's only possible to create a super user for a new installation."

Because you've been successful to create the super user, you don't have a
new installation. For security reasons I implemented the restriction that
it's only possible to create a super user in a empty member table
(tblMember). As soon as you have at least one entry in this table, calling
the task with the request type "createSU" will return the message above.

The problem remains that 1.) you get german error messages and 2.) you get
an error calling http://localhost:8080/vifapp/admin/.
My interpretation is that the application is not able to access
vif.properties.
If it would have been able to read the settings in this file, it would have
been switched to english (org.hip.vif.dftLanguage=en) and knows about the
place of the stylesheets and html-pages (org.hip.vif.docs.root=...).

Maybe you should tell me more about your configuration and environment, i.e.
where you installed Tomcat, how you start it, how you debug the application
etc.

Benno

This is ok. However, this setting is only last resort. If the startup is
successful, the application uses the language setting defined with
org.hip.vif.dftLanguage=en in vif.properties.

> I got a message which was not in english. SO I guess I

The message should be "The super user suId has been created successfully."
I thought, this is english, but as my mother tongue is not english, I might
be wrong :-)

Well, if you got the following response: "Der Super User suId wurde
erfolgreich erzeugt." then you got the german version of the success
message.

However, you could check in the table tblMember in your database, whether
the entry for the application's su has been created. If yes, you could go
further.

If the message you got matches the german version above, you still seem to
have some problems to read the vif.properties file. The application reads
this properties file in org.hip.kernel.sys.VSys.getVSysProperties(). Maybe
you can debug this method to check what it does.

Benno

Dear Swati

AbstractXSLView inherits from org.hip.kernel.servlet.impl.AbstractHtmlView.
In the initialize() method of this class, both constants DOCS_ROOT and
WEB_ROOT are initialized by reading the values from the properties file,
e.g.:
   DOCS_ROOT =
VSys.getVSysProperties().getProperty(DOCS_ROOT_PROPERTY_NAME);
A value 'null' means that the application was not able to read the file
vif.properties.

Please check again whether your really started Tomcat from the directory you
placed vif.properties.

Benno

Dear Swati,

Here some remarks to the vif.properties you sent me:

>org.hip.vif.db.password=
For this property you must provide the password of the DB-user VIF. I guess,
you left this empty in the file you sent me for security reasons ;-)

>org.hip.vif.docs.root=C:\Program Files\Apache
Group\Tomcat\webapps\vifapp\admin\
The properties nees slashes '/' and not back-slashes '\' for path
specifications. That might be the cause of the error. So the following
property is better:
org.hip.vif.docs.root=C:/Program Files/Apache
Group/Tomcat/webapps/vifapp/admin/

In the properties file I use when I implement I only made
org.hip.vif.docs.root absolute and left the other properties (i.e.
org.hip.vif.docs.root and org.hip.vif.logPath) relative. That works fine for
me. Please try if the same holds for you.

> Anyways, I am trying to set up the project in my Jbuilder.
Good.

> Is there any documentation about this.
Unfortunately not. I'm using Eclipse as my IDE.

> 1.What are the libraries needed to be included in the
> project so that it compiles.
You need all the libraries deployed in your
Tomcat\webapps\vifapp\WEB-INF\lib directory except, of course, vif.jar (the
application) and viffw.jar (the applications framework).

> 2. I have set the output path of my Jbuilder to
> \Apache Group\Tomcat\webapps\vifapp\WEB-INF\classes ...
Eclipse has a Tomcat-plugin. This makes it possible to run Tomcat and debug
the application from the IDE. Maybe you theres a Tomcat-plugin available for
JBuilder too.

Good luck,
Benno

Dear Swati

Thanks for sending the log.
The important information is the following:
08.05.2003 20:00:50 > ... java.io.FileNotFoundException:
nullnull\err_msg\body.xsl (The system cannot find the path specified)

The reason for this error message is that the application's main properties
file vif.properties contains relative path specifications to find the
application's templates:
org.hip.vif.docs.root=./webapps/vifapp/admin/

Try to replace this property with an absolute path specification, e.g.:
org.hip.vif.docs.root=C:/programs/Apache_Tomcat_4.0/webapps/vifapp/admin
or the like.

Tomcat makes it possible to deploy an application together with all class
libraries needed in one war-file. You'll find these jar-files in
$TOMCAT_HOME\webapps\vifapp\WEB-INF\lib (where $TOMCAT_HOME is the path to
your Tomcat installation). E.g. the JDBC is in mm.mysql-2.0.5.jar.

Hope this helps.
Benno

Dear Swati,

The actual number of tables in the database needed for the application is
19, correct and congratulations.

=========
> Also what does the following command mean:
> %~f1\mysql --user=root --password=%2 -D vif -v < table_tblRole.sql.

Here the meaning of the various parts in the command above:
%~f1 : means expanding the parameter 1 as file-path, in your case
%~f1\mysql could expand to "c:\mysql\bin\mysql", i.e. a call to the
mysql-application with the following parameters:

--user : which user is connecting? In this case it's the user with the
user-id "root"

--password : which password has the user? The password is provided as secons
parameter to the script

-D : which database shall be connected? In this case it's the database
identified as "vif"

-v : tells the application to write the output verbose

< table_tblRole.sql : tells the mysql-application that it should work in
batch mode and that it should process the commands in "table_tblRole.sql"

=========
> ERROR:
> Failed to open file
> '\vif_projectcript\mysqlable_tblMemberHistory.sql',

I don't understand this error message.
What happens if you enter:
c:\mysql\bin\mysql --user=root --password= -D vif -v < table_tblRole.sql
in the directory where the MySQL scripts are stored (I guess
C:\vif_project\scripts\MySql)?

=========
> EXCEPTION
> java.lang.NullPointerException
> ...

This seems to be a follow-up error. Therefore, I don't see the error which
originally caused this message.
Can you locate the error.log. In this log file, you'll find the whole
sequence of error messages and I hope, one of them is more understandable
then the one you sent me.
The place of the log files (i.e. error.log, system.log, tracer.log) depends
on the setting in the application's properties file "vif.properties". You
there have to look for the property "org.hip.vif.logPath". Probably the path
to the log files is relative. Relative in this case means relative to the
application's working directory.

The problem you encountered might be caused by the fact that you didn't
place the files "vif.properties", "GROUPSTATES.xml", "QUESTIONSTATES.xml"
and "ROLES.xml" in the working directory. If you start Tomcat with a Windows
shortcut from the Windows Start menu, you have to make sure that Tomcat is
startet in the directory you want it to be startet (see the entry "Start
in:" in the shortcut's properties tab). A good choice is the Tomcat's root
directory $TOMCAT_HOME. By default, the entry "Start in:" (i.e. the working
directory) points to place completely unintuitive.

I guess, you'll be successful soon.
I'll suggest that you subscribe to the project's mailing list
(vif...@li...) and send your questions and remarks to
this address. That helps to document the project's various difficulties and
problems.

Regards,
Benno

Dear Swati

I guess I see the problem.
If you take a look into the InstallDb.bat file, you see that this script
calls two other scripts: VIFCreate.bat, and CreateTables.bat.

"call" is a regular command at the Windows NT/XP command prompt. However, it
seems that this command is not known on the Windows 95/98/Me os. Therefore
the message "Bad command or file name".

A simple workaround would be: Do the job the script should have been done
yourself. You can do this by typing:
C:\vif_project\scripts\MySql>VIFCreate c:\mysql\bin
C:\vif_project\scripts\MySql>CreateTables c:\mysql\bin

Hope that helps.
If you find the correct command which calls one batch program from another
on Windows Me, please tell me.

Regards,
Benno

Good news.

In general, you need all of them.

> 2. How do I download the project on my machine from
> sourceforge.
The simplest way is to download the whole vif-Rel0.3.3.tar.gz package from
http://sourceforge.net/project/showfiles.php?group_id=29728, to unpack the
tar.gz file and then to proceed as described in
http://vif.sourceforge.net/InstallAndRun.html.
The package, however, has 5.03 MB. I hope, bandwith is not a problem for
you.
The advantage to proceed this way is that you get not only the compiled and
the source code, but also the documentation, the installation scripts for
the database and the additional jar files needed to run the application.

> 3. Minimum database required to start coding at this
> point.
After running the InstallDb.bat you'll have the vif-database organized the
way needed to run the actual release of the application and to develop the
next steps.
Actually, there are 19 tables needed to run the application.

Regards,
Benno

Dear Rashi

If MySQL shows up in the taskbar, thats a good sign.
Try to start mysql.exe from the command prompt in the \bin directory of your
MySQL-Installation (e.g. c:\programs\mysql\bin). mysql.exe is a simple
database client for your MySQL-DB. After starting, you see the mysql prompt.
Enter 'use mysql' to connect to the default (i.e. infrastructur) DB.
You can enter there SQL commands like
select * from db;
select * from host;
select * from user;
and so on.
For more information you can consult '4.13.4 Running MySQL on Windows' in
\MySQL\Docs\manual.html.

If you can start mysql.exe and if you connect to the mysql database (via
'use mysql') you should be able to create the vif database. You can do this
by starting InstallDb.bat at the command prompt of the \scripts\MySql
directory of your VIF installation. This script creates the vif database and
the tables and indexes needed for the application so far.

Hope this information is helpful.

Regards,
Benno

Dear Swati/Rashi

I've installed MySQL on Windows2000, Window XP and Linux without problems.
According to the download page Windows 95/98 are supported and, therefore, I
conclude Windows Me should be supported too. Until now I worked with Version
3.23.

After you've installed the program in a directory, e.g. c:\programs\MySQL,
the setup program will install the application's documentation under
c:\programs\MySQL\Docs. The documentation is quit extensive. I found all the
information I needed.

Please tell me if you encounter problems with your MySLQ installation on
Windows Me.

Recently I fount a very good DB client which supports (among other things)
MySQL. Its name is Aquad Data Studio and you can download it under
http://www.aquafold.com/ .

Benno

The tblPerson table is used to store biographic information, which could be
referenced in the discussion forum. The tblText table is used to store
bibliographic information that could be referenced. The application also
stores the author and reviewer responsible for the entries in tblPerson and
tblText. See the VIF datamodel for further information about table
specifications and the relations of these tables within the whole datamodel.

I'll describe here the needed steps for tblPerson. The case for tblText is
analogous.

a) Database: You have to create the table tblPerson according to the
specification in the datamodel. A script table_tblPerson has to be created
and the installation scripts CreateTables.bat and CreateTables.sh have to be
adjusted. The scripts table_tblPersonAuthorReviewer.sql and
table_tblTextAuthorReviewer.sql exists yet.

b) Model: Because the domain object PersonAuthorReviewer and its home exist
already, only the domain object for tblPerson has to be created. To do that,
you have to create the interfaces Person and PersonHome for the domain
object and its home. After creating the interfaces, the implementations
PersonImpl and PersonHomeImpl have to be created. The implementations of
existing domain objects can be taken as sample.

c) Controller: Create the tasks PersonListTask, PersonShowTask,
PersonNewTask, PersonEditTask and PersonSaveTask in the package
org.hip.vif.admin.tasks.impl. The first task lists all existing entries in
tblPerson, the second task shows a specified entry, the third task creates a
new entry, the fourth task is needed to edit an entry and the last task
saves changed data to the table.
Note: The newly created tasks have to be registered to TaskManagerImpl. You
can take the existing implementations of AdminQuestionListTask,
AdminQuestionShowTask etc. in the package org.hip.vif.admin.tasks.impl as
sample.

d) View: Create the views (Java classes and XSLT). The Java views prepare
the produced XML for that they can be transformed by the appropriate XSLT
files. Take existing views and stylesheets as sample.

Regards,
Benno

Hello

Here's the description and specification of Use Case 3 "Post a contribution"
(see http://vif.sourceforge.net/RequirementsAndSchdule.html).

Description:
A Participant looks for an open question and makes a contribution. A
contribution consists either of information useful to answer the question or
in a division of the original question into various subsequent questions.
This use case is applicable after the administrator has created a discussion
group and added one or more questions. A further prerequisite is that enough
members have registered to the discussion group, thus becoming participants
of this group. The sequence of this use case is as follows:
The participant navigates to the question she wants to post a contribution.
The participant chooses either to make a contribution that possibly can
answer the question or to subdivide the original question into various
subsequent questions.
The participant fills the form displayed.
After posting the form data, the application creates a bookmark. Then the
application chooses assigns a reviewer from the other participants in the
discussion group. After that, the application sends the bookmark both to the
author and reviewer. In a subsequent use case the reviewer can publish the
contribution.

Specification:
Based on the description above, the implementation of this use case consists
of the following steps:
a) Model: Because the domain objects Question, QuestionHistory,
Contribution, ContributionHistory, LinkGroupQuestion,
LinkContributionQuestion and their homes exist already, only the domain
object tblBookmark has to be created.
To do that, you have to create the interfaces tblBookmark and
tblBookmarkHome for the domain object and its home.
After creating the interfaces, the implementations tblBookmarkImpl and
tblBookmarkHomeImpl have to be created.
The implementations of existing domain objects can be taken as sample.

b) Controller: Create the tasks QuestionListTask, QuestionShowTask,
QuestionNewTask and QuestionSaveNewTask in the package
org.hip.vif.forum.tasks.impl.
The first task lists the questions of the discussion group. The second task
displays the content of an existing question. The third task allows to add a
new question to an existing question. The last task saves the data entered
for a new question.
Note: The newly created tasks have to be registered to TaskManagerImpl.
You can take the existing implementations of AdminQuestionListTask,
AdminQuestionShowTask, AdminQuestionNewTask and AdminQuestionSaveNewTask in
the package org.hip.vif.admin.tasks.impl as sample.

c) View: Create the views (Java classes and XSLT). The Java views prepare
the produced XML for that they can be transformed by the appropriate XSLT
files.

Regards,
Benno

Hello

Here's the description and specification of the next use case (Use Case 12,
see http://vif.sourceforge.net/RequirementsAndSchdule.html).

The use case starts after the group administrator logged into the VIF
administration application. The list of discussion groups the administrator
is administering is displayed. The group administrator selects one that is
created but doesn't have a starting question yet. Text fields for the
starting question and for additional explanations are displayed in a form.
The group administrator enters the starting question and additional
information and submits the form. The system saves the information and
creates a unique decimal identification for the contribution.
There's no workflow needed at this point since the group administrator has
the right to publish contributions immediately and without review.

The information submitted by the group administrator is added in the tables
tblQuestion (for the starting question) and tblContribution (for additional
information) (see Datamodel). Each discussion group consists of various
questions, which have to be linked to the group by the table
tblLinkGroupQuestion. Each question can be accompanied by various
contributions, i.e. explaining information. Therefore, the table
tblLinkContributionQuestion links contributions to their questions. Each
essential information has to be historised so that changes can be traced
back and rolled back. Therefore we need two additional tables
tblQuestionHistory and tblContributionHistory.

Therefore, the implementation of this use case consists of the following
steps:
a) Model: Create the interfaces for the domain objects Question,
QuestionHistory, Contribution, ContributionHistory, LinkGroupQuestion,
LinkContributionQuestion and their homes QuestionHome, ContributionHome etc.
After creating the interfaces, the implementations QuestionImpl,
QuestionHomeImpl, ContributionImpl, ContributionHomeImpl etc. have to be
created. The implementations of existing domain objects can be taken as
examples.
b) Controller: Create the tasks AdminContributionShowTask and
AdminContributionSaveTask. The first task controls the display of the form,
the second saves the data submitted by the group administrator. Note: The
newly created tasks have to be registered to TaskManagerImpl.
c) View: Create the views (Java classes and XSLT). The Java views prepare
the produced XML for that they can be transformed by the appropriate XSLT
files.

Benno
