Running the Asynchronous Aspect or any others aspects outside of JBOSS server
is quite straitghforward.
They are differents options of deployment based on your requirements (See
Reference doc Chap 10)
I personally tested two configurations with Tomcat 5.0
JDK 1.4 using the precompiler.
------------------------------
Create a war file as follow :
WEB-INF/lib/concurrent.jar
WEB-INF/lib/jboss-aop.jar
WEB-INF/lib/jboss-aspect-library.jar
WEB-INF/lib/jboss-common.jar
WEB-INF/lib/javassist.jar
WEB-INF/lib/trove.jar
WEB-INF/classes/META-INF/jboss-aop.xml
WEB-INF/classes/...
JDK 1.5 (Loadtime)
-------
Modify the classpath as follow ( Use the Configure Tomcat dialogbox)
-Djava.system.class.loader=org.jboss.aop.standalone.SystemClassLoader
Create a war file as follow :
WEB-INF/lib/concurrent.jar
WEB-INF/lib/jboss-aop-jdk50.jar
WEB-INF/lib/jboss-aspect-library-jdk50.jar
WEB-INF/lib/jboss-common.jar
WEB-INF/lib/javassist.jar
WEB-INF/lib/trove.jar
WEB-INF/classes/META-INF/jboss-aop.xml
WEB-INF/classes/...
An alternative for both options (JDK 1.4/JDK 1.5) is to install
the libraries under CATALINA_HOME/common/endorsed and the jboss-aop.xml
under CATALINA_HOME/common/classes so u don't need to package them with the war
file.
2/The Asynchronous Aspect does catch all exceptions.
So in order to test ,if the asynchronous method raises an exception do the
following :
For example if the method execute was annotated with the asynchronous
annotation.
POJO p = new POJO();
long value=p.execute();
AsynchronousFacade facade = (AsynchronousFacade)p;
// Test if the method raised an exception and get the Exception object.
if (p.getResponseCode()==AsynchronousConstants.EXCEPTIONCAUGHT)
{
((Exception)p.getResponseObject()).printStackTrace();
}
The following constants are also available :
AsynchronousConstants.OK (Asynchronous method completed succesfully)
AsynchronousConstants.TIMEOUT (Asynchronons method completed but did timeout)
AsynchronousConstants.NOVALUE (Asynchronous method still running)
I hope it helps .
