The best place to put these JAR files is into your applications package. For example if your application is packaged as a WAR file, place them in WEB-INF/lib within your WAR. If your package is an EAR, place them in the base directory of the EAR and reference them in your META-INF/application.xml file. Another alternative is to add them to the server/xxx/lib directory.
