I wrote a post a few days ago about using Jersey 2.x as a shared library with WebLogic 12.1.2. In that post I suggested the following: In weblogic.xml the prefer-application-packages element needs to have entries added for ALL OF THE PACKAGES in the Jersey 2.x shared library JAR files. That means you need to go through every jar file in WEB-INF/lib for the shared library that was created with Maven and make sure the packages it defines are included in this element.

Now that is a tedious process and I thought that is something that could be automated. I spent a bit of time on the weekend putting together a script just for that. The script will go through all JAR files in a directory specified on the command line and will generate a list of unique <package-name> elements that can be used in weblogic.xml.

The script can be found on GitHub: ikromin/j2ee/weblogic_xml_cpgen/gencp.sh.

Here's a sample output of this script:
