vif-devel Mailing List for VIF (Page 6)

Hello

I've released Release 0.2.0 of the application VIF.
This release includes the following changes:
- Bug corrected which prevented proper initialization.
- Bug corrected which prevented ORDER BY ordering.
- Migrated framework to use the Transformation API (TrAX) for XSL
transformation.
- Made all lists sortable (by clicking the icon in the column header).

Hello

I've released a new version of the application VIF with the release number
V0.13.

I've made a revision of the domain object framework. I added database
adapter functionality.
With these extensions the application know is able to interact not only with
MySQL, but with further databases like Oracle, PostgreSQL ect. With this
design new adapters for further databases can easily be added to the
framework.

I revised the documentation for the domain object framework too (see
http://vif.sourceforge.net/DomainobjectMetamodel.pdf). I've added some
examples so it should be more comprehensible.

Regards,
Benno

Implementation hints for use case 2

The aim of the use case 2 is the registration of members to a discussion =
group.=20
With the use cases of the administration application implemented until =
now we're able to create members and discussion groups. The next step, =
therefore, is to provide the functionality that members can register to =
a discussion group through the forum application, before they are able =
to contribute to the discussion in the chosen group.=20
The use case starts when the member calls the list of available =
discussion groups. The member marks all the groups she wants to =
contribute. The application checks whether the member is not yet =
registered to the selected groups and, if not, registers it. The =
application then sends a feedback to the member's browser. This use case =
results in new entries in the table tblMembership (which links members =
(i.e. entries in tblMember) to discussion groups (i.e. entries in =
tblGroup)).
The implementation of this use case consists roughly of the following =
steps:

a) Model: Create the domain object Membership and its home =
MembershipHome (i.e. the interfaces and their implementations). This =
domain object is used to handle the data in tblMembership. You can take =
the table specification from the data model documentation. You can take =
org.hip.vif.bom.impl.GroupAdminHomeImpl etc. as guideline.

b) Controller: Create a task (e.g. GroupRegisterTask) which handles the =
members request to register. I think we have to create another task =
(e.g. GroupShowRegisterListTask) which shows the available groups and =
displays checkboxes which the member can mark. You can take =
org.hip.vif.forum.tasks.impl.GroupShowListTask as guideline. Note that =
you have to register the newly created tasks to TaskManagerImpl.

c) View: Create the views which prepare the produced XML for that they =
can be transformed by an appropriate XSLT. You can take =
org.hip.vif.forum.servlets.impl.GroupListView as guideline.

Regards,
Benno

Dear Mac

That's good. I wonder now whether the Apache error you reported =
originates from the same error. Could you check this?

Regards,
Benno

Hey there;
    I set the path : 
org.hip.vif.docs.root=c:/jakarta-tomcat-4.0.1/webapps/vifapp/admin/
and I was able to enter as super user using suID and suPasswd..........

                         thanx MAC

Dear Mac

The path to the file looks well now. As the error continues, I suppose that
the application still doesn't find the specified file. You specified a
relative path declaration, which means relative to the Tomcat's working
directory.
I suggest you to try an absolute path declaration to the /vifapp/admin/
directory in a first step. If the error continues, there's a serious problem
and I would need further information to solve it. If the error disappears,
you have to calculate the correct relative path if you prefer to specify a
relative path in vif.properties.

Regards,
Benno

Hey there;
    I changed :

when I try to set SuId

                thanx Mac

Dear Mac

This XSL Error usually means that the system couldn't find the specified
file.
This error seems to be the same you encountered at the beginning of this
month and it has to do with the ending slash that is needed for the property
org.hip.vif.docs.root in vif.properties.
According to the error message the application looks for the file in a
"adminde" directory, but it should be "admin/de", where "de" denotes the
language description for language specific files.

BTW: You can change the installations default language to english by setting
the property org.hip.vif.dftLanguage=en.

Regards,
Benno

Dear Mac

I didn't run VIF with Tomcat in combination with Apache. Therefore, I
appreciate it very much that you investigate this combination.
I can only give you some suppositions concerning the error that you
encountered. I guess the problem has something to do with the way Apache
maps or redirects the relative paths.
Did you check the log files? Probably the browser requested a file the
application doesn't find anymore.

Regards,
Benno

Dear Oleg

Which version of the application do you try to install?
I'm developing on Windows (which is not case sensitive) and released =
Version 0.1. I then tryed to install this version on Linux and got the =
same problems you discribe. I found out that reason is that Linux and =
MySQL on Linux are case sensitive. The application V0.1 transforms all =
table names in upper cases, but the installations scripts create tables =
in mixed cases. Therefore, the application doesn't find the specified =
tables and returns the SQLException instead (which isn't very =
instructive ;-) ).
I corrected this error in V0.11.
If my guess that you're using V0.1 is true then I would simply suggest =
that you try to install V0.11 or V0.12. If the problem you discribe =
continues, we have to look at MySQL again.

Regards,
Benno

Dear Mac

I need more information to help in this case. Can you send the messages
logged in the application's log files? You can find them according to the
property "org.hip.vif.logPath" in vif.properties.
The application maintains three log files: system.log, tracer.log and
error.log.
The most descriptive information in the case of this error should be in
error.log (as you might suppose).
Do you get this error only when adding new members? Does adding new groups
and setting new permissions work?

Regards,
Benno

Hey there;
     Thanx it finally worked with the backslash. I get an error when I try

Dear Oleg

According to the error message you encountered the same problem Mac did some
days before.
The message says that the application can't find the properties file
XMLImplementation.properties. This file and the other files (vif.properties,
GROUPSTATES.xml, ROLES.xml) must reside in Tomcat's working directory.
The working directory is the directory you are in when submitting the
command for startup Tomcat. For example if you are in
/opt/jakarta-tomcat-4.0.4/bin (in this example the directory the file
startup.sh resides) and you enter the command ./startup.sh, this makes
/opt/jakarta-tomcat-4.0.4/bin as working directory. But if you are in
/opt/jakarta-tomcat-4.0.4 and submit the command ./bin/startup.sh, in this
case /opt/jakarta-tomcat-4.0.4 is your working directory.
Therefore, the place to copy the files vif.properties,
XMLImplementation.properties etc. depends on the way you start Tomcat.
The same holds on Windows, only the naming of the paths is a little bit
different. If you start Tomcat by clicking on a shortcut, you can set the
working directory in the shortcut's properties.

An other problem Mac encountered was that the application couldn't find the
template files to display the information in the browser window. The
application gets this information from the property "org.hip.vif.docs.root"
in vif.properties. You either can set an absolute path or a path  relative
to Tomcat working directory.
Be aware that this property (and the property "org.hip.vif.website.root")
needs a trailing slash.

Regards,
Benno

Hello

I've released a new version of the application VIF with the release number
V0.12.
Here are the changes:
- Added functionality to handle guest/anonymous user.
- Modified java scripts so that genereated html work with netscape too.

Regards,
Benno

Dear Mac

The property "org.hip.vif.docs.root" needs a trailing slash. Therefore I
guess C:/unzipped/jakarta-tomcat-4.0.1/webapps/vifapp/admin/ should work on
your PC.

The necessity of trailing slahes is a little bit inconsistent in
vif.properties and therefore may be confusing. Perhaps I change this in a
future release.

Regards,
Benno

Dear Farzad

I agree with you concerning the deployment argument. Ant gives us any
freedom to choose the CVS directory structure. Therefore, we have not to
bother about this point anymore.

The other point is Tomcat. I identify two sub points there: (1) Tomcat as
productive environment for the application and (2) Tomcat integrated in the
IDE used for debugging and testing the application during development.

(1)	I think Tomcat is a good choice as servlet application container: It is
open source, stable and having a war file, the installation of an
application is very simple. But maybe we find a way to produce the project's
deliverables not targeting a specific application environment with an
installation procedure which is comparable in it's simplicity to the Tomcat
way. So we can put this point by for the moment.

(2)	Tomcat/CVS in the IDE: In your response you didn't deal with my notes
about working with Tomcat and CVS during the development process. I fear
that organizing the files in the CVS makes development for me (and other
developers using Eclipse or IntelliJ IDEA or comparable IDEs) a lot harder
without great benefits for other users. What do you think about this
impression?

Regards,
Benno

Dear Mac

The reason for not getting any html displayed is that the application =
couldn't find the appropriate XSLT files. Therefore, you have to adjust =
in vif.properties the property "org.hip.vif.docs.root". You can enter an =
absolute path to the root directory of the applications   xslt and html =
files, e.g. C:/programs/tomcat/webapps/vifapp/admin/ (for the VIF Admin =
application) or C:/programs/tomcat/webapps/vifapp/forum/ (for the proper =
VIF application). If you prefer to enter a relative path, you have to =
remember that the path is relative to the Tomcat working directory.

Regards
Benno
