I am using jboss5.1.0GA. Here is the issue: I have a third party jar packaged in a manifest jar using relative path. After putting the manifest jar in server/lib, the server code (a custom startup class) can NOT find the classes in the third party jar. /dev/jboss/server/default/lib/myjar.jar /dev/team/third_party/jar1.jar in myjar.jar manifest: Class-Path: ../../../../team/third_party/jar1.jar So I need to walk up the chain and then come down to another path for the library. -rw-r--r-- g900 55824 Oct 27 16:56 ../../../../team/third_party/jar1.jar it verifies that the relative path for the jar is correct! Now if I directly put the third party jar under server/lib, the classes are found during server startup and everything works fine! /jboss/server/lib/jar1.jar I need to use the manifest mechanism as there would be dozens of third party jars, defined in another dev location during install and I like to avoid the duplication by dumping all to the server lib directory. Any insights on this issue? Thanks, jboss_ottawa View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4263057#...
