Hi, I have developed some applications on my SAP Portal using JCo. Now I have this error:

Hi,

In the system you created, try to maintain Fully Qualified Domain Name.

That should solve the issue.

please refer to the link below to create the system.

Before getting to your application, first of all, check the connection test of your JCOs. Is it success/Failure?

With the kind of logs you are showing, it should fail. Generally, while you install the server, the sapinstall does take care of all the permissions and services setup.

Hi,

Check your JCO connection settings.

- hostname and port number specified for the R/3 system is correct?

- sapgw<nr> is the gateway port. check the same in Transacation SMGW.

- check in your services.msc file and included the hostname and port of the R/3 system you are trying to connect.

Ensure your R/3 system is up and running.

What I'have to do in services.msc?THANKS

The entry will be something like

sapmsJ2E 3601/tcp

where J2E is the instance name and 3601 is the message port.

Thanks,

Smita.
