Hi, I tried to build various versions of JBoss, but unfortunately not successfully. I have no idea what failed. Here is what I did: 1) downloaded the respective sources (i.e., jboss-4.0.2-src.tar.gz, jboss-4.0.3SP1-src.tar.gz, jboss-4.0.5.GA-src.tar.gz, jboss-4.2.2.GA-src.tar.gz) 2) unpacked the file 3) ran ant from the build directory In all the cases I got 1 error and the build failed. BTW, I am able to compile/build successfully various other Java programs. Has anyone experienced the same problems? Thanks, Stephanie
