Access query string from web service class?

[Frank Xia]

There is a need for me to access HTTP request query string from a service
class. Anyone knows is it even possible? 

Here is an example, 

http://localhost:8080/axis/servlet/AxisServlet?Nation=USA&State=NY
<http://localhost:8080/axis/servlet/AxisServlet?Nation=USA&State=NY> 

I would like to get two parameters of Nation and State from the URL

Thanks
