4.2.2 & 4.2.3 working EAR, does not work on 5.0.0

[cloggs996]

I get the exception message:
"Error deploying bad magic number: cba78dd8"

The EJB (in the EAR) is fairly basic and I have tried to keep it as minimal as possible; There is a class which implements @Remote & @Local interfaces. The ejb-jar.xml file looks like this:
<enterprise-beans>

<display-name>xxx</display-name>
<ejb-name>xxx</ejb-name>
<ejb-class>com.xxx.xxx.xx</ejb-class>
<session-type>Stateless</session-type>

</enterprise-beans>

As the title states, this EAR works on 4.2.2 & 4.2.3.

All help appreciated!

Thanks

More details please, including the entire exception stacktrace and the console logs. Also post your ejb-jar.xml, jboss.xml(if any) and the relevant bean code.

While posting logs or xml content or code, remember to wrap it in a code block by using the Code button in the message editor window. Please use the Preview button, before posting, to ensure, your post is correctly formatted.

P.S: There's a forum specifically for JBossAS5 questions http://www.jboss.com/index.html?module=bb&op=viewforum&f=287

I created a skeleton EJB/EAR replicating the one I want to use (but minus the added application). This works fine in all of the JBoss version.

I would like to know if this could indicate a problem with the dependencies?

If my EJB contains jars that clash with the JBoss ones would this cause such an error?

Thanks,
