SINGLE ejb jar deploy gives NoClassDefFoundError!

[zeron]

Hello All,

Jboss 3.2.3

I am a JBoss newbie.. 2 days only.
I was really surprized how easy it is to deploy something under JBoss, but then things went bad.

I'm trying to deploy a single ejb. No external dependencies.. nothing.
It is packaged in a single jar file like this:

mycomp/
--- /ejb/myejb/
--------/AAAHome.class
--------/AAABean.class
--------/AAA.class
--------/AAAException.class
--------/model/
----------------/Foo.class
----------------/Bar.class
META_INF/
---ejb-jar.xml
---jboss.xml


There is nothing out of ordinary in ejb-jar.xml or jboss.xml they define only one SLSB ejb.

when I copy the provision.jar (the ejb I want to deploy) to the server/default/deploy folder, the deployment starts but fails with this exception:

Which methods throw the missing exception?

[zeron]

Hi

All the methods in AAA.class and AAABean.class throw the exception AAAException.
Very simple, no?

Am I missing something really basic here???

Thanx
