Subject Re: Bean deployment on Tomcat error
Date Thu, 08 May 2008 03:35:07 GMT

Something very strange happened. I updated my OpenEJB to 3.0 (actually I
installed a fresh copy of both Tomcat and OpenEJB), and now the Listener
gets installed (unlike the case with 3.0beta2), after deploying my .war it
no longer immediately dissappears from Tomcat's list of apps but I never get
a Jndi name for it (and I was getting one with beta2)...

Here are the logs:

[openejb.log]
------------
Configuring app: C:\Java\tomcat\webapps\SimpleSessionApp
INFO  - Loaded Module: C:\Java\tomcat\webapps\SimpleSessionApp
INFO  - Assembling app: C:\Java\tomcat\webapps\SimpleSessionApp
INFO  - Deployed Application(path=C:\Java\tomcat\webapps\SimpleSessionApp)
------------

You see, I no longer get "Jndi(name=SimpleSessionBeanRemote)" etc.

[catalina.2008-05-09.log]
------------
May 9, 2008 5:11:02 AM org.apache.catalina.startup.HostConfig deployWAR
INFO: Deploying web application archive SimpleSessionApp.war
------------

I left the whole previous conversation quoted so you can see both my code
and previous errors.
Also, here's what I've done to package my EJB, the problem might as well lay
there:

jar cf SimpleSessionApp.war beans\*.java

Only the two classes listed below are within beans package (they were
successfully tested on JBoss and no code was changed when deployed to
OpenEJB/Tomcat instead).

I'm sorry for bothering you with an unconstructed question like this but I'm
very new to all this...
