Invoking Solman WS from Eclipse

Friend,

I am absolutely new to SAP. I was given the URL of SAP Solution Manger web services and was asked to consume it via Lotus Notes. I thought it fit to - first use a Eclipse based Webservice explorer to research a little bit. I am able to connect to the webservice, see all the function it exposes. I am able to get a systemguid when I invoke the operation 'RequestSystemGuid' . But when I use this to get a list of unclosed incident - I get the following error. I am posting the Soap Response here. Could any please tell me what is it that I have to do at the SAP Sol Man end to make sure that I get the list of unclosed incidents ? I am invoking the web service from Eclipse on my lap top. Let me know if you need more information ?
