Semantics of Remove
Hmm,
I'm playing around with stateful sessions, but if calling a @Remove annotated method of a bean i cannot lookup a new session bean of the same class.
What am I doing wrong, or didn't i get it right that calling such a method
should close the session instance?
I created an EJB Project and deployed it successfully, then i deployed a web-app for the frontend on the same container.
I created a Test-Servlet for showing the error:
int i = -1;
try {
InitialContext ctx= new InitialContext();
SeminarSession seminarSession = null;
for (i = 0; i < 10; ++i) {
seminarSession = (SeminarSession)
ctx.lookup(SeminarSession.class.getName());
// select Seminar with id 1
seminarSession.select(1);
// quit and remove the session
seminarSession.quit();
}
} catch (Throwable e) {
log("Error in round " + i);
throw new ServletException(e);
}
When executing the console says the following:
10:08:33,447 INFO [Engine] StandardContext[/MeinwerkWeb]TestAction: Error in round 1 10:08:33,462 ERROR [Engine] StandardWrapperValve[TestAction]: Servlet.service() for servlet TestAction threw

Can anybody please help me out!?
Could it be a config error?
Im running JBoss 4.0.1 with EJB 3.0 Preview 3.
