Hi, I have a problem with Ant. ant worked before I install JBoss application server. And after installation, I get Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/tools/ant/launch/Launcher error. I'm using fedora linux and there was pre-installed ant. It seems that JBoss installed another version of ant. But I can't figure out how to make it work as before. After I don't want to remove ant and reinstall because there are too many dependency with ant and I don't want to remove them all. Does anyone know how to fix this problem? Please help me.
