NoSuchObjectException

[shai koren]

hello
I did see few messages with such problem but none was replied...
We are trying to deploy our application on the client's environment
(Borland 4.5.1 on Solaris).
We have a problem with the ejb's deployment and to isolate the problem
we wrote different test jsps. We found that the lookups are fine and the container
actually gets the stubs alright, but when a method of this stub is executed a
java.rmi.NoSuchObjectException: CORBA OBJECT_NOT_EXIST 0[]
is thrown.
code:
...
<%
UserManagerHome userManagerHome;
UserManager userManager ;
String str = null;
try {
javax.naming.Context context = new javax.naming.InitialContext();
Object ref = context.lookup(JNDI_USERMANAGER);
//log.debug(thisClass + " got the ref " + ref);
userManagerHome = (UserManagerHome) javax.rmi.PortableRemoteObject.narrow(ref, UserManagerHome.class);
//log.debug(thisClass + " before calling create " + userManagerHome);

userManager = userManagerHome.create();

//log.debug(thisClass + " got the userManager " + userManager );
str = userManager.sayHello(); // this method should return "hello world" string

%>
OK got the String <%=str%><br>
<%
}
catch (javax.naming.NamingException e) {

%>
FAIL (NamingException) <br>
<%=e.getMessage()%><br>
<%
e.printStackTrace();
log.writeStackTrace(e);
}
catch (Exception e) {
%>
FAIL (Exception) <br>
<%=e.getMessage()%><br>
<%
e.printStackTrace();
log.writeStackTrace(e);
}

%>

few more points about it:
- The same code runs nicely on number of different environments ( NT/Linux , Borland/Orion etc..), which suggest it is an environment specific problem
- The same thing happens with Entity but then it happens on the Home's stub.
- From looking in the spec i realized that this exception is thrown by the container as a wrapper to "lower level" or
CORBA exception that occured or when the refered object does not exists.
- In the event_log i see that there is one session bean in READY state.
- looking in the stub's code where the exception thrown in line 272 shows that :

catch (org.omg.CORBA.SystemException ex) {
throw javax.rmi.CORBA.Util.mapSystemException(ex);
}
I doubt if it's anything to do with the deployment descriptors, could it?
What could have gone wrong that triggered the org.omg.CORBA.SystemException to begin with?
Could it be related to environment settings or configuration?
Has anyone faced this problem before?
Any ideas, sugestions or thoughts will be very appreciated.
Thanks
