I had the same issue today. I solved it by changing the port from the message port to the P4 port on a single instance installation. So changing from 50000 to 50004 solved it for me.

Hi

I am facing the same issue.

Both in Dev and QA systems it was working fine, but when we deployed this in prod we are getting the same error>>

ava.lang.ClassCastException: class $Proxy2764_10000:sap.com/DemoJMSEAR at com.sap.engine.boot.loader.ResourceMultiParentClassLoader at 3fe3e77e at alive incompatible with interface com.sap.aii.af.lib.mp.module.ModuleLocal:library:com.sap.aii.af.lib at com.sap.engine.boot.loader.ResourceMultiParentClassLoader at 5fb39192 at alive

we have two hosts in Prod server, i have used one to deploy the user module. I am not seeing any options in NWDS to change the port number.

There is some problem with adapter module. We redeployed it and it worked fine.

Hello.

How did you correct your module. I've got the same error and no idea what's wrong.

Beans is Stateless.

I trust you recoded the custom adapter to fit PI 7.1. In that case I would guess that you're using a stateful interface, and your adapter can not handle that.
