There are three main perpesctive in WSAD .. a server,
j2ee and
java.
In what per. do u want to create the client Application.
Normally in the all the perc. the folder structure is different.
If you want to make your own (new) client application go to the j2ee perctive.
right click and you find the Application Client Project .. click that n go ahead with the options you need.
Servlets and
Jsp's are all placed under Web Modules that you can see in the same directory.
I too started working recently on the tool.
Hope it helps you ....
