COMPAS J2EE is a non-intrusive performance instrumentation and monitoring toolkit for J2EE. It uses adaptive monitoring to automatically adjust the target coverage. COMPAS is completely portable across J2EE application servers and OSs.

JLayerCheck checks package dependencies in Java projects to ensure that they match the desired architecture. Packages are grouped into modules and dependencies are specified. It can also find cycles and orphaned classes.

Objectreferenceanalyser (ORA) helps finding memory leaks, design weaknesses and bugs. The ORA-Framework visualizes objects, their content and relations during runtime of any Java application and is able to persist these findings for subsequent analyze.

ParTeG (PARtition TEst Generator) handles UML state machines, UML class diagrams and their OCL expressions. The OCL expressions are evaluated to find input parameter partitions. The boundaries of these partitions are used to generate test cases.

PopperFramework is a java framework which allows you to create PageObjects for your webapplication-tests in a declarative way. That means you just have to define an interface defining the structure of your website and add some annotation with the basic information like locators. PopperFramework will generate the implementation of that PageObject for you. Key-Goal of PopperFramework is to allow you as a developer of sureface-tests to concentrate on your business => writing PageObjets and Tests, not wasting time by writing boilerplate code. PopperFramework uses WebDriver-API to implement your PageObjects but its API is completly vendor-independent. So when there comes something better than WebDriver you change the implementation of PopperFramework and change to the vendor you need. PopperFramework is highly configurable with a lot of hooks which allow you to customize PopperFramework behaviour to your needs.

SQLOrm focuses on mediating database interaction rather than shielding the user from it. SQLOrm consists of 3 major parts. A dynamic query builder. A prepared statement layer. A resultset to object graph mapper, supporting batch inserts/updates.

SeSAm (Shell for Simulated Agent Systems) provides a generic environment for modelling and experimenting with agent-based simulation with a special focus on the easy construction of complex models including dynamic interdependencies or emergent behaviour

netCCM Studio is a component-based modelling tool.
