Hi,

This is difficult to answer this way, Can you tell me exactly what error are you facing while testing the JCO connection.

I faced one error which got resolved by this

After creating Jco destinations in webdynpro content administration you need to maintain the entry for

for sapms<SID> <port> in

\windows\system32\drivers\etc\services file of the j2ee server(source system).

Where <SID> is the sid of the target system you are connecting to and port is the message server

port mentioned in the SLD during registration of the target system. Without this entry the jco connection test will fail.

If it doesn't solve let me know.

Best Regards,

Hi,

The error is when I try to create a JCo for Meta data I get an error message saying the JCO Error: com.sap.mw.jco.JCO$Exception: (102) JCO_ERROR_COMMUNICATION: JCO.Client not connected in repository call.

IT would be great if you can send me an answer.

Thank you

Sunil
