Hi
I am running into an issue with remote object lookup after a Jboss Server
restart.
I am running JBoss 4.0.5 GA.
I have a test case that does the following -
*test client creates Init Context with properties and successfully looks up a
remote EJB interface.
*test client closes init context
*test client sleeps for 45 seconds.
*In the meanwhile the JBoss server is restarted.
*The test client wakes up and creates a new initial context with same props as
before
*Test client tries to look up the same remote EJB interface as before.This time
the look up fails with java.rmi.NoSuchObjectException: no such object in table.
*Even if the test client looks up a different remote EJB interface the same
exception is thrown
The relevant code snippet from the test client is below
| InitialContext ctx = new InitialContext();
|
ctx.addToEnvironment("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
|
ctx.addToEnvironment("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");
| ctx.addToEnvironment(InitialContext.PROVIDER_URL,"my-hostname");
| Object beanobj = ctx.lookup("MyService/RemoteIAdmin");
| assertNotNull(beanobj);
| ctx.close();
| try {
| System.out.println("Waiting for 35 seconds. Restart Jboss now!!");
| Thread.sleep(45 * 1000); // wait for 30 seconds
| System.out.println("Done sleeping. Will do second lookup now");
| } catch (InterruptedException e) {
| e.printStackTrace();
| }
| InitialContext ctx_1 = new InitialContext();
|
ctx_1.addToEnvironment("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
|
ctx_1.addToEnvironment("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");
| ctx.addToEnvironment(InitialContext.PROVIDER_URL,"my-hostname");
| Object beanobj_1 = ctx.lookup("MyService/RemoteIAdmin");
| assertNotNull(beanobj_1);
|
The exception occurs on the second lookup the stack trace is as follows
| javax.naming.CommunicationException [Root exception is
java.rmi.NoSuchObjectException: no such object in table]
| at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:722)

I turned on rmi debug for both server and client using
-Dsun.rmi.loader.logLevel=verbose but I wasnt able to discern much from the log
output
I did a bit of reading on the jboss forums and wiki but none of the solutions
listed has helped me. Readings include
-http://wiki.jboss.org/wiki/Wiki.jsp?page=IGetNoSuchObjectException
