Unable to create JCO connection from WebDynPro

[Former Member]

Hi,

I am able to create a JCO connection using single server method from WebDynPro but when i am trying Load Balance method the system is prompting a message <b>"com.sap.mw.jco.JCO$Exception: (102) JCO_ERROR_COMMUNICATION: JCO.Client not connected in repository call"</b>.

Please advice.

Hi Venkatramana,

Exception caused by network problems, connection breakdowns, gateway problems, unavailability of the remote SAP system, etc may be reason for this .

JCO_ERROR_CONNECTION

get the host of the SAP System from dev_jrfc.trc or the JRFC trace; ping the SAP system from command line; check routers, gateways, SAP systems

HI Venkatramana

I think its the problem with the message server.Just check if Message server port is opened .If not ask basis guys to open the port for you.

Hi,

Yes, it seems the problem is with message server only,but the port is open.

Please suggest if the problem is anything else.

Thanks,
