The ejb3 ClientContainer is expecting to find an env entry under the applicationClientName name on the server: | public ClientContainer(ApplicationClientDD xml, Class<?> mainClass, String applicationClientName) throws Exception | { | this.xml = xml; | this.mainClass = mainClass; | this.applicationClientName = applicationClientName; | | //Context ctx = getInitialContext(); | Context ctx = new InitialContext(); | enc = (Context) ctx.lookup(applicationClientName); | NamingEnumeration<NameClassPair> e = enc.list(""); | while(e.hasMore()) | { | NameClassPair ncp = e.next(); | log.debug(" " + ncp); | } | encEnv = (Context) enc.lookup("env"); | | However, how the client enc is expected to function is that the lookup of "java:comp/env" maps to the server side context bound under the applicationClientName. There is no server side env under the client. The deployment was a j2ee 1.4 deployment. We need to merge the client deployer logic and client container. What refactoring were you going to be doing on the ejb3 client? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3992676#...
