Eclipse helios Servlet creation wizard fields are blank

Am trying to create a simple servlet using servlet creation wizard in helios(eclipse). A popup opens up and when I type the class-name, at开发者_如何学JAVA the top of the popup I can view a red cross mark which says 'The Source folder cannot be empty'. There is Browse bttn available, so when I click and go there, a popup opens but do not allow me to select anything in it. Please help me in this. Thanks

Creating Servlets by wizard only work for projects of type Dynamic Web Project. Truncate your current project and recreate it using New > Project > Web > Dynamic Web Project wizard.
