Open source software APIs

Open source software APIs

The WebSphere Application Server product includes a variety of open source software packages.

The specific version provided by the product might vary over time. To understand what version is currently provided, a developer can extract the META-INF/MANIFEST.MF file from the JAR files in the plugins or dev directory and look for an Export-Package: directive. The version of each package is listed in this directive.

Open source software not intended for direct application use

Some of the open source software included in the product is not intended for direct application use. This might be for a variety of reasons such as the package is not included entirely or it has been modified with WAS specific behaviors. Applications that want to use these packages or want to use different versions of the open source software listed can override the WAS included open source packages with their own. This requires packaging the open source software in the application and setting the classloader policies of the module and application to load classes from the parent last.

This is the list of software not intended for direct application use:

Apache Commons Digester
Apache Bval
Apache Commons Collections
Apache Commons EL
Apache EL
Apache HTTP Components
Apache Jasper
Apache MyFaces
Apache Neethi
Apache Sandesha2
Apache Taglibs
Apache Tuscany
Apache WS Commons
JBoss Javassist
Simple Logging Facade for Java (SLF4J)
