When I attempt to use the @Asynchronous annotation as described in the reference manual
(section 17.1.1. Asynchronous methods) I receive an InstatiationException with the message
"Could not instantiate Seam component: org.jboss.seam.core.dispatcher". I have
narrowed down the issue as follows:
Asynchronous method in interface SystemManager.java
| @Asynchronous
| public void asyncTest();
Implemented in SystemManagerBean.java
| public void asyncTest(){
| System.out.println("This is a test of async method.");
| }
Called from Manager.xhtml
| <br/><h:commandButton value="Call Async Test"
action="#{systemManager.asyncTest}" />
Dispatcher added to Components.xml
| <core:dispatcher/>
I am using Seam 1.2.1 on a Glassfish server. I am able to use a commandButton to call
other methods in the same bean from the same jsf page, but when I call the
"asyncTest()" method I get the stack trace shown below.
Any suggestions are appreciated.
