[EJB 3.0] - Re: Can't get a stateless session bean to work - JNDI can't
by sbucknor
Hi all, I have a similar issue too. I am experimenting with EJB3 deployed on JBoss 4.0.5 (the jar installer version). The deployed jar file (called SimpleSession.ejb3) has 2 classes:- SimpleSession.class (remote interface) and SimpleSessionBean.class (the bean). This deploys with no issues but from a JSP client calling the EJB with the following code
String theString = null;
InitialContext ctx = new InitialContext(); simpleSession=(SimpleSession)ctx.lookup(SimpleSession.class.getName());
theString = simpleSession.sayHello();
I get the following error message:
10:52:55,968 ERROR [STDERR] javax.naming.NameNotFoundException: beans.SimpleSession not bound
10:52:55,968 ERROR [STDERR] at org.jnp.server.NamingServer.getBinding(NamingServer.java:529)
10:52:55,968 ERROR [STDERR] at org.jnp.server.NamingServer.getBinding(NamingServer.java:537)

10:52:55,968 ERROR [STDERR] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)
Etc....
I also noted that the bean was registered with JBoss from the service=JNDIView parameter on the jmx-comsole.
Does anyone have an idea of what could be wrong here. Any Help will be much apreciated.

[JBoss jBPM] - possible nonthreadsafe access to session
by TheEJBPope
Hi,
When trying to delete a process instance from the web application, I'm getting the exception underneath.
It seems to be related to subprocesses. When the "super-process" includes a call to a sub-process, it runs and ends normally but can't be deleted via the jbpm web application any more. When running the process without the sub-process included, it can be deleted.
Anyone any clue ?
Btw, I'm using jbpm 3.1.2 with the corresponding starter's kit.

[JBossWS] - Re: tool support for Stub based client programming model
by muted
I'm also looking for information on how to create the client-side stubs. Looking at the (poor) documentation for wstools, it looks like it can only create the server-side stubs. That was my experience, I have a valid wsdl file created with the tools used on the endpoint server, which is running on a different platform. When I use wstools as specified in the WS documentation and wiki, the only code I get is the server-side stubs which do not help me at all.
I browsed through the wstools configuration XML and it seems that it only specifies ways to create the server-side java code.
I'm really new to web service coding and until now have just used ready modules created by others in the company. However, everyone here is new to JBoss so a few examples or the correct instructions on how to use wstools to create the client-side stubs would be appreciated.
