[jboss-dev] Use cases for manipulating AS classpath

Hi guys, Can you give me a usecase where it is useful to add jars to the AS classpath (JBOSS_CLASSPATH/RUN_CLASSPATH in the run.sh scripts) and not just add them into lib folder ? Asking since it is a constant "battle" in the tooling between users who want full control and those who just want the server startup to *always* work. Before we go add a bunch of complex code to handle this I would like to know of a use case that merits that users can set the classpath at startup time instead of just adding it into lib. The usecases I have come up with I'm not sure if they are valid: 1) allows me to put stuff on the global classpath of the server without manipulating a possibly read-only lib directory 2) Needed if you want to enhance the run.jar and other classes for profiling/debugging purposes 3) Allows you to try a patch on run.jar without changing the possible read-only AS directory Anything else ? Are those 3 usecases *valid* or is there better ways of doing that ? From a tooling users perspective I believe (though not yet confirmed) that bullet 1 is the reason why they want it - thus I would like to know if doing point 1 is semantically equal to putting that jar in the lib dir of the server or the config. Or are there some (user perceived) difference ? /max
