Hi,

First of all please check if you haven't made an typo in the channel name and business system. Maybe one letter is missing.

Hi,

Check if communication channel exist in

http://<host>:<J2EE port>/CPACache/monitor.jsp.

If not refresh the CPA Cache.

Also check cache notifications in ID.

Thanks,

Hi,

Have you been in communication channel monitor in Runtime workbench? What is the status of that communication channel? Maybe it's stopped 😎

Hi ,

Have you checked all the possibilities, which are written in the API?:

1. if an exception occurs while unmarshalling the call header

2. if the protocol for the return value is invalid

3. if a java.io.IOException occurs unmarshalling parameters (on the

server side) or the return value (on the client side).

1. if a java.lang.ClassNotFoundException occurs during unmarshalling

parameters or return values

1. if no skeleton can be loaded on the server-side; note that skeletons

are required in the 1.1 stub protocol, but not in the 1.2 stub

protocol.

1. if the method hash is invalid (i.e., missing method).

2. if there is a failure to create a remote reference object for a

remote object's stub when it is unmarshalled.

Or

Should these rmiregistry smart enough to try either of these protocols,

or the gnu version is too old?

Hi,

Make some changes in the channel say for instance, change the description. Save and activate it. Go to Environment Clear SLD Data Cache and try again. It should work.

Hi,

Deactivate and activate the channel again in ID and test.
