jboss 3.0.1 Deployment problem

[tonala]

I have been referred to this forum by the Persistence & CMP people.

First a bit of background:

I was attempting to deploy a file that had previously deployed without error on jboss 3.0 alpha.

However, on jboss 3.0 final the following occurred:

3.0.0RC3/server/default/deploy/hl7.jar
java.lang.ClassFormatError: net.niat.entity.SuperEntityBean$Proxy (Repetitive method name/signature)

I had never seen this Repetitive method error before so I asked about it and was advised to upgrade to jboss 3.0.1.

Things went poorly with 3.0.1 and my hl7.jar so I tried another file (perf.jar) one that deploys perfectly with 3.0 final.

This is part of the exchange from the other forum:

Actually this is a CMP question.

Your perf/SubSection is not deploying.
It is looking for a type mapping for "true".

Look in server/default/conf/standardjbosscmp-jdbc.xml

I have jbosscmp-jdbc.xml as a part of the deployment. It contains the type mappings for mySQL pasted in from the jboss distribution.

If what you say is true, why would the deployment work on 3.0 and not on 3.0.1? It seems something in jboss has changed.

Let me ask this if I may. My original question and problem was that on 3.0 I am getting an error:

3.0.0RC3/server/default/deploy/hl7.jar
java.lang.ClassFormatError: net.niat.entity.SuperEntityBean$Proxy (Repetitive method name/signature)

It was in response to this error that Dain advised me to upgrade to 3.0.1, which I did spawning the matters above.

I can't tell from the message what the problem really is. I tried looking for a duplicate method somewhere but there is none of that.

Any thoughts? Thanks.

Can you post some information about the class
and its interfaces.

Do you inherit from the same interface twice in
different parts of the hierarchy?
I've seen this break some reflection based routines
when switching to java 1.4, including Sun's jmx
implementation.
One easy way to check this is to run javadoc over
your classes. You will see the method twice, under
different classes.

If you do see this problem, it is a bug in the
ProxyComplier.

Regarding the ClassFormatError: This is now listed in the bug database as bug #607895.

In hopes it will be solved soon
