[jboss-user] [JBoss Seam] - Re: Missing exceptions within asynchronious methods

[gbc@gmx.de]

Ok, full working example code, tested just now. 

First post regarding the missing RuntimeException (Second post follows later after coding example...):

Interface:

  | package org.esit.server.sessionbeans;
  | 
  | import javax.ejb.Local;
  | 
  | @Local
  | public interface Blob {  
  |     
  | 	public boolean isAvailable();
  | 	
  | 	public void raiseBlob();
  | 	
  | 	public void observeBlob();
  | 	
  | 	public void destroy();
  | 	
  | }
  | 

SessionBean:

  | package org.esit.server.sessionbeans;
  | 
  | import javax.ejb.Remove;
  | import javax.ejb.Stateful;
  | 
  | import org.jboss.seam.annotations.Begin;
  | import org.jboss.seam.annotations.End;
  | import org.jboss.seam.annotations.In;
  | import org.jboss.seam.annotations.Name;
  | import org.jboss.seam.annotations.Observer;
  | import org.jboss.seam.core.Events;
  | import org.jboss.seam.faces.FacesMessages;
  | 
  | @Stateful
  | @Name("blob")
  | public class BlobAction implements Blob {
  | 
  | 	@In FacesMessages facesMessages;
  | 
  | 	@In Events events;
  | 	
  | 	public boolean isAvailable() {
  | 		boolean out = true;
  | 		facesMessages.add("isAvailable(): #0", out);
  | 		return out;
  | 	}
  | 
  | 	@Begin
  | 	@End
  | 	public void raiseBlob() {
  | 		facesMessages.add("raiseEvent() called");
  | 		events.raiseAsynchronousEvent("blob");
  | 	}
  | 	
  | 	@Observer("blob")
  | 	public void observeBlob() {
  | 		System.out.println("blob");
  | 		throw new RuntimeException("blob");
  | 	}
  | 
  | 	@Remove
  | 	public void destroy() { }
  | }
  | 
  |

  | </ui:define>
  | 
  | </ui:composition>

Fresh seam-gen project, no further configuration gives only following Server output on JBoss 4.2 (using Java 1.5 Beta 12 and Seam 2.0 Beta1):

  | ...
  | 23:31:40,437 INFO  [STDOUT] blob
  | ...
  | 

But no sign of the RuntimeException. I tried to throw the RuntimeException in method raiseBlob() directly and voilá, there it is as expected.

Missing RuntimeException, where are you?

Note: Just tested without

  | 	@Begin
  | 	@End
  | 
with same effect
