Hi,

I wanted to test the REST connectivity from a stand alone java code. Since the couldnt find an example online i modified the current rest demo available in the salesforce api to use SOAP login instead of oAuth login. I read somewhere in this forum that we can use the soap login to obtain the user sessionId which can be used to make rest api.  So I tried to modify the rest demo code as shown below . I was able to connect successfully to salesforc test environmet and get the session id. I m i using this session id in place of the the accesstoken to set the get method's request header. But now i m getting a connection time out error .  I  did set the proxy host and port correctly so I doubt it can be a proxy issue as i was also able to connecti using the SOAP Enterprise connection. I m not sure i m doing this the right way can someone please guide me or point out any mistakes i made ?
