There were some changes made to the wsrunclient.sh script between jbossas 5.0 beta3 and beta4, and the new script is incorrect. For example: $ ./wsrunclient.sh -classpath some/class/path my.java.Class agr1 arg2 arg3 Exception in thread "main" java.lang.NoClassDefFoundError: arg3 Apparently, the changes made in the script were tested only with the class name being the last argument passed to the script. If I replace the script with the one in beta3, then all is well again. (By the way, the wsrunclient.bat script works correctly in beta4.) Should I file a JIRA?
