How to set attributes in URL to call a servlet in gwt + java?

Question

I want to open a file stored on server on click of a button on client side. On click handler I added code-

 String url="../../downloadServlet?fileName="+fileN+"?recodId="+recoId;
 Window.open(url, "", "");  

In this url , I want to add 2 diffrent parameters- FileName and RecordId. Above implementation is not working for this. How can i pass more parameters in a request?

Thanks

try to use & instead of another ?:

String url="../../downloadServlet?fileName="+fileN+"&recodId="+recoId;
