[Former Member]

I have posted in Web Dynpro Java but not sure that is right plave and once again posting it here...

I am getting following error while testing JCO Connection.

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed Connect_PM TYPE=B MSHOST=sapserver GROUP=SPACE R3NAME=IDS MSSERV=sapmsIDS PCS=1 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR max no of 100 conversations exceeded TIME Sat Jan 19 20:42:40 2008 RELEASE 700 COMPONENT CPIC (TCP/IP) with Unicode VERSION 3 RC 466 MODULE r3cpic.c LINE 10713 COUNTER 1

I increased profile parameters rdisp/max_comm_entries = 200 but it doesnot help so I change it back.

Any idea what is problem?

Thanks

Hi,

At what stage do you get this error.

Do you have a ABAP stack as well as a JAVA stack or is the JAVA STACK inside ABAP.

What steps are you taking that leads to this error?

Thanks

The error I am getting at the time of connection testing with ABAP system.

I have ABAP + JAVA on same server. And recently I have added GRC on JAVA. I have created JCO Destination for GRC pointing to ABAP system and client. At the time of connection testing of Ping I am getting an error of communication error.

Thanks
