local class incompatible

[nort]

Hi,

I try to run an EJB application. When I execute my client i get this exception:

javax.naming.CommunicationException. Root exception is java.io.InvalidClassException: org.jboss.invocation.jrmp.interfaces.JRMPInvokerProxy; local class incompatible: stream classdesc serialVersionUID = 4948756606502181321, local class serialVersionUID = -3713605626489646730

Does anyone can say what this mean?

Thank you,

It means the class has changed between
jboss releases and there is no serialVersionUID
on the class.

Make sure the client jars are from the same
version of jboss.

I generate the client.jar with ant - RMIC. Is this not possible? When i run the exampel with J2EE-RI it works.

i want to set up a build management with ANT and XDoclet to generate Stubs and DDs for different EJB Containers.

It doesn't work the same way in jboss.
We have already used RMIC to generate
a detyped stub.
JBoss then passes metadata to the client
telling it how to run your specific ejb proxy.
This means you don't have to do any compiling
for the client side. Just make sure the client
has the correct ejb interfaces and you are
using the correct jboss client jars.

Hi,

thank you for your explication. Can you tell me where to find some docu for this point? Perhaps a tutorial would be very nice (JBOSS 3.0.X).

Or can you tell me quickly what to do and to attend.

The stub is in jboss-client.jar or
jbossall-client.jar

Make sure the client has the version
from the server's ${jboss.dist}/client
