Pradeep,

As Ayax suggested:

If your EP is windows, go to

WINDOWS/system32/drivers/etc/

edit file "services"

Add this string:

sapgw03 3303/tcp # SAP System Gateway Port

After that either restart the entire EP or recycle server nodes.

EP will pick up the entry and JCo will start working.

Your error does not indicate that the entry is missing on the R3 system, but the same entry should be there too.

Check it in your Portal and your ECC server.

Check that you have defined sapgw03 in your services file, it should be an entry liky this:

sapgw03 3303/tcp # SAP System Gateway Port
