I have a project consists two parts: RAP-based web UI part and
EJB3-server part. Second path consists 23 EJB3-application. All works
fine. The UI-part successfully interact with server-part.
Now I need to add some functionality which interact with other ejb3
application on the same server. I create a simple action:
new Action(){
@Override
public void run() {
Logger debugger = Logger.getLogger(this.getClass()); //Log4j logger
String DEBUG_STR = "run: ";
debugger.debug(DEBUG_STR + "start");
debugger.debug(DEBUG_STR + "security manager " +
System.getSecurityManager());
Class<?> forName;
try {
forName =
Class.forName("com.company.docprint.as.mngrs.DocTypeManager ");
debugger.debug(DEBUG_STR + forName);
forName =
Class.forName("com.company.docprint.as.mngrs.DocTypeManagerBean ");
debugger.debug(DEBUG_STR + forName);
forName = Class.forName("org.jboss.ejb3.JBossProxy");
debugger.debug(DEBUG_STR + forName);
forName = Class.forName("javax.ejb.EJBObject");
debugger.debug(DEBUG_STR + forName);
forName = Class.forName("javax.ejb.EJBAccessException");
debugger.debug(DEBUG_STR + forName);
Context ctx = new InitialContext();
Context c0 = (Context) ctx.lookup("DocManagerBean/remote");
//throws exception
// Context c0 = (Context) ctx.lookup("AbonentServer/remote");
// works fine
}
catch (Exception e) {
debugger.debug(DEBUG_STR + e, e);
}
debugger.debug(DEBUG_STR + "stop");
}
}
A exception occurs when I try to run this code fragment from
RAP-application.
If I change
Context c0 = (Context) ctx.lookup("DocManagerBean/remote");
to
Context c0 = (Context) ctx.lookup("AbonentServer/remote");
all works fine. The "AbonentServer" is the EJB3 from old server-part.
If I run the code fragment from JUnit test case - all works fine.

Environment:
Eclipse 3.4.1
RAP 1.2M2
Jboss 4.2.1
OS Fedora Linux 8 x86_64
Java 1.5.0_14 x86_64
Where is the problem? Why I can connect to one EJB but can't to other?
