I am trying to compile the Duke's bank application code for Jboss i have followed all the steps which are mentioned in Getting Started with JBoss 4.0 guide. I have downloaded the source code for the duke's bank application from sun's web site and then i have downloaded jbossj2ee-src.zip from the JBOss site and then extracted this zip file under j2eetutorial14 directory (which is a duke's bank application src dir) and then i have modified jboss.properties file to set the jboss home. After that i tried to compile the code using jboss-build.xml ant script but it's failing to compile. I am getting following error org.jboss.ws.jaxrpc.ServiceImpl class is not found. Please tell where can i find the jar file related to the above class file.
