You can try to either: 1 - put the ant libraries from tools/lib to your ant lib directory and you ant like you tried. *or* 2 - use the embedded one, unfortunately few things are not done right in this package and need a fix, go to the build directory and type the following commands: | cd ~/jboss-portal-2.4.1-src/build | dos2unix build.sh | dos2unix ../tools/bin/common.shlib | chmod u+x ../tools/bin/ant | dos2unix ../tools/bin/ant | sh build.sh | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4016320#...
