title: How to switch between python and java using eclipse
body: <p>I have just installed pydev on eclipse to write a simple python project. Now I would like to switch back to using java in eclipse. In my project explorer window I do not see any of my java projects. When I go to file-> import -> Existing Projects into Workspace, all of the java projects are greyed out (not selectable). Do you know how I can switch between python and java using eclipse?</p>
