I have the jbpm-enterprise.ear deployed in Weblogic 9.2.3. The jndi to the data
source is also setup. I wrote a message driven bean to invoke jbpm with the
following onMessage() method:
public void onMessage(Message msg) {
| try {
| InitialContext ctx = new InitialContext();
|
| RemoteCommandServiceHome commandServiceHome =
| (RemoteCommandServiceHome)
ctx.lookup("ejb/CommandServiceBean");
| RemoteCommandService commandService =
commandServiceHome.create();
| commandService.execute(new
NewProcessInstanceCommand("MyProcessDef"));
| }
| catch (NamingException e) {
| // TODO Auto-generated catch block
| e.printStackTrace();
| }
| catch (RemoteException e) {
| // TODO Auto-generated catch block
| e.printStackTrace();
| }
| catch (CreateException e) {
| // TODO Auto-generated catch block
| e.printStackTrace();
| }
| catch (Exception e) {
| // TODO Auto-generated catch block
| e.printStackTrace();
| }
| }
However, I got the "Could not instantiate TransactionManagerLookup" error when
the message is received:
