Same for me I was looking for this Jar. I don't have jbossws14-core.jar Instead I have : \server\default\deploy\jbossws.sar\jbossws-core.jar\org\jboss\ws\jaxrpc\ And here I can only find a ServiceFactoryImpl.class Where is the ServiceImpl ? I need it to test the Duke's Bank application on my installation from the JBoss "Getting Started". (step 4.1.2) I am using jboss-4.2.2.GA Thanks a lot, View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4120097#...
