Hi,
I'm relatively new to SalesForce so bear with me if this seems very stupid.:mansad:

I am trying to run the Sample java code with SalesForce web service. I get a NullPointerException when i try to log in. I have a developers account whose login/password combination i am using.

The following statement executes fine.
Code:

binding = (SoapBindingStub)new SforceServiceLocator().getSoap();

However when i try to login using this binding i get the exception at this line
Code:

binding.login(userName, password);

Here userName and password are my developer account's user name and password in String.
The stack trace hints that the initial error is occuring at com.sforce.soap.enterprise.SoapBindingStub.login(SoapBindingStub.java:1781)

Any idea what should I do to resolve this?
