5:50 a.m.
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);
|
| Properties props = new Properties();
| props.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jboss.naming.NamingContextFactory");
| props.put(Context.URL_PKG_PREFIXES,
"org.jboss.naming:org.jnp.interfaces");
| props.put(Context.PROVIDER_URL, "jnp://localhost:1099");
|
| Context ctx = new InitialContext(props);
| 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?
