[jboss-user] [JBoss Seam] - ejb + seam from swing gui
We've made an application with jsf +seam +ejb and it works great, I am so pleased, but
I think it would be nice if I could be able to use the same ejb beans (application logic)
from client such as swing or anything else.
I did try an it partially works, injections work, entity manager controlled by seam also
work.
Our application uses long running conversations and transactions are controlled by seam
also flushmode is manual.
So I need to start conversation manually and set flushMode.Manual.
I tried it like this but it does not work
This is method from ejb which should start conversation
| @Begin(flushMode=FlushModeType.MANUAL)
| public String pocetak() {
|
| return "OK";
| }
|
This is part of client swing application
| ref = jndiContext.lookup("java:kadrovska/ObradaTestBean/remote");
| ObradaTest obrada = (ObradaTest) ref;
|
| obrada.pocetak();
| ......
|
I get this error:
| Exception in thread "main" javax.ejb.EJBException:
java.lang.IllegalStateException: Do not start long-running conversations in direct calls
