help in configuring portlet developer

Hi friends,

I need help in Installing the Portlet Developer on Eclipse. As i have done all the steps indicated in Portal Design Guide, like selecting

a) webMethods portlet form builder
b) wmPortal developement for Eclipse

after installing this, i have configured portlet developer by setting the preferences. Atlast i found WebMethods Portlets in Open perspective.As they said in PDF

The wmPortal Components tab provides a tree view of your portlets and the elements of
which they are composed. The Navigator tab provides a tree view of the file structure of your portlets.

But i cant find the tree view , what shall i do next. Please if anyone helps …
