Hi Fenil,
I remember i faced similar error sometime back.
Can you cross check below points once again:
1. Check installed plugins latest version in Eclipse kepler (Help menu >About Eclipse>Installation Details) It should be 1.1.3
API toolkit for SAP Mobile Platform
OData Modeler
2. When you created a new project, you must have selected Target Runtime server as "SAP Mobile Platform 3.0 SP03 or lower" as you are working on SP03. Right?
3. Are you working on the same machine (eclipse installed) where SMP3 server is installed?
4. Can you just check if you have set any proxy details in SMP3 props.ini file under C:\SAP\MobilePlatform3\Server by any chance?
Also, in eclipse, Windows>Preferences>Network Connections>Active Provider>Manual
Note: If possible, upgrade to latest runtime SP05 as it has many new features and bugs resolved wrt to IGW.
Regards,
JK
