Dear experts, I have an EAR containing some jar files (one with interfaces and POJOs, one with Session Beans, ...), which is correctly deployed and working in JBoss 5, and I'm trying to access some of the Session Beans methods from a separate WAR , which contains GWT based application.
I did a test using the WAR deployed in hosted mode (with the tomcat delivered by GWT) , and I managed (putting the needed jar with the interfaces + the jboss client jars in the CLASSPATH) to access the session beans from the REMOTE interface. Now I'm trying to test the same but deploying the war inside JBoss 5, and I'm having lots of problems related to (I think) classloading issues. I read several posts on the forum, but I did not manage to succeed, while a similar application was working in Jboss 4.2.2. Just to summarize what I have in the WAR : there is a WEB-INF/lib containing only gwt-servlet.jar there is a WEB-INF/web.xml containing servlet definitions there is a WEB-INF/classes containing all the code there is the stuff generated by GWT... I also have a jndi.properties at the root level of the WAR, containing some parameters for jndi : | java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory | java.naming.provider.url=jnp://dapmcf121:1099 | java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces | client.method=local | web.host.url=http://dapmcf121:8080 | and here is where I try to retrieve the interface : | if (clientmethod.equals("local")) { | log.info("Getting local stub using jndi"); | InitialContext ctx = new InitialContext(); | tagDAO = (AligntagBD) ctx.lookup(SERVER_NAME | + "/AligntagBDBean/local"); | } | (in case it helps...) I did try to set in file deployers/jbossweb.deployer/META-INF/war-deployers-jboss-beans.xml the parameter useJBossWebLoader=true but nothing changed in the error message which is the following: | |
