Could not create python view in Eclipse

Question

I' ve installed PyDev plugin to Eclipse. When I am creating new python project I have to switch to Python view. Unfortunately I get this message:

Could not create the view: An unexpected exception was thrown.

How to deal with it?

Answer 1

I had the same problem when I got the new release of Pydev. I went to pydev.org installation instructions and noticed Java 7 is now required. Once I upgraded Java--and made sure Eclipse was using the new version--the problem resolved itself.

Answer 2

Although you're having the problem when starting PyDev package explorer, the real problem is with another plugin -- it can't find org.eclipse.jst.servlet.ui.EnhancedJavaRendering, so, I'm guessing it's some problem in the installation of webtools.
