I believe definitly that BIRT dosen't work with jboss. The error is follow: eclipse.buildId=unknown java.version=1.5.0_06 java.vendor=BEA Systems, Inc. BootLoader constants: OS=linux, ARCH=x86, WS=motif, NL=en_US Command-line arguments: -clean !ENTRY org.eclipse.osgi 4 0 2007-01-07 17:17:56.704 !MESSAGE Bundle org.eclipse.equinox.common@2:start not found. it occurs in org.eclipse.osgi.framework.internal.core.Framework. (URLStreamHandlerFactory stepping on previously installed) it always seems when I redeploy my .ear application. I don't known how to solve this. Anyone have any idea?
