I have checked the services file and all the entries are present there, could any one help me in fixing this error?

One additional thing to try is to run netstat to see if the port is up and check to see if another service has bound to that port 3300. You can also try using telnet to attach to the port to see if you get a response (i.e. 'telnet localhost 3300').

Hope that is helpful.

Hi,

Thanks for your response, The JCo's in Visual Admin are working fine.

coming to the SAPGW00, I dont think we have the gateway installed on the NW system. Unable to do Telnet for the port 3300.

Any suggestions for this?

Thanks.

Don't you have gwrd process running ?

[Former Member]

Hi Vincent,

Where do I check this gwrd service?

We have NW 7.1 with Java(No ABAP), do I have to have a dedicated SAP Gateway??

Could you please elaborate on this?

In the Visual Admin->Server->Services->JCo RFC Provider I am using the SAPGW00 of the ECC(ABAP) system.

Unable to determine where this is checking for the SAPGW00 in the Java engine...

Thanks in advance

If you can run SMGW in your ABAP stack then you should be able to confirm that it is running. You can also run ST11 to view the file 'dev_rd' to see if there was an issue on startup.

Are you possibly running your java stack on a different system from your ABAP stack?

Hello Chiluveru,

Such errors are written when the connection to the gateway fails.

For example if the configuration is wrong in the JCo RFC Provider service of the J2EE Engine.

You could use Visual Administrator to access the JCo RFC Provider.
