Thanks. I edited my build.xml below | <path id="build.classpath"> | <pathelement location="${basedir}"/> | <fileset dir="${jboss.home}/lib"> | <include name="**/*.jar"/> | </fileset> | <fileset dir="${jboss.home}/server/${jboss.server.config}/lib"> | <include name="**/*.jar"/> | </fileset> | <fileset dir="${jboss.home}/server/${jboss.server.config}/deploy/ejb3.deployer"> | <include name="*.jar"/> | </fileset> | <fileset dir="${jboss.home}/server/${jboss.server.config}/deploy/jboss-aop-jdk50.deployer"> | <include name="*.jar"/> | </fileset> | <fileset dir="${lib.dir}"> | <include name="**/*.jar"/> | </fileset> | <!--fileset dir="${cache.lib.50.dir}"> | <include name="**/*.jar"/> | </fileset--> | <pathelement location="${classes.dao.dir}"/> | <pathelement location="${classes.web.dir}"/> | <pathelement location="${classes.test.dir}"/> | <pathelement location="${conf.hivemind.dir}"/> | </path> | | <!-- pre-compile directory with aopc --> | <target name="aopc" depends="compile" description="Precompile aop test classes"> | <taskdef name="aopc" classname="org.jboss.aop.ant.AopC" classpathref="build.classpath"/> | <aopc compilerclasspathref="build.classpath" verbose="true"> | <src path="${classes.dao.dir}"/> | <aoppath path="${cache.resources.dir}/jboss-aop.xml"/> | <classpath refid="build.classpath"/> | </aopc> | </target> | It use the same jar, also should be in sync. But the problem remains. :( View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3999774#...
