Configuration: Jboss AS 3.2.6 / Jboss IDE 1.0 / Eclipse 3.0.1
When I deployed the FiboApp.ear, I didn't get POP-UP dialog but no warning either. The messages are shown in the console:
10:38:17,870 INFO [EjbModule] Deploying Fibo
10:38:18,150 INFO [EJBDeployer] Deployed: file:/D:/jboss-3.2.6/server/default/tmp/deploy/tmp60983FiboApp.ear-contents/FiboEJB.jar
10:38:18,260 INFO [TomcatDeployer] deploy, ctxPath=/fibo, warUrl=file:/D:/jboss-3.2.6/server/default/tmp/deploy/tmp60983FiboApp.ear-contents/FiboWeb.war/

10:38:18,771 INFO [EARDeployer] Started J2EE application: file:/D:/jboss-3.2.6/server/default/deploy/FiboApp.ear

But the last line in the tutorial was missing: [MainDeployer] Deployed Package: ....

When I tried on http://localhost:8080/fibo/ example, the web page returned the following message:
HTTP Status 405 - HTTP method POST is not supported by this URL

I did implement doPost method in the servlet, how comes I still get this?
