Sugar CRM - Java Client - login

I was trying to develop a Java application which gets contacts from Sugar CRM. I have newly installed Sugar CRM 6.0.2 and I did not make any modifications to it. I am making use of the inbuilt SOAP based WebServices (have to use soap cant go for rest based) to login. But while logging in I am getting an error message saying:

anyType{
    id=-1; 
开发者_StackOverflow中文版    error=anyType{
        number=10; 
        name=Invalid Login; 
        description=Login attempt failed please check the username and password;
    };
}

I am sending a string user for user_auth parameter:

1. String user = "user_auth{username=will; password=18218139eec55d83cf82679934e5cd75; version=1.0;}";
2. String user = "{'user_auth':{'username':'will','password':'18218139eec55d83cf82679934e5cd75', 'version':'1.0'}}";

I tried both of the above options and its not working. I tried "SugarCRM" and "CRM" for application_name.

If anyone of you can help me regarding this that would be a great helpful for me. Thanks.

There is a bug in SugarCRM. You may only log into the WebServices with Admin.

And you can't pass JSON Strings to SOAP. You have to pass XML using SOAP.
