Hi,

I'm running Eclipse Juno / WIndows 7 / Java jdk1.7.0_21 / GWT - 2.5.1 / App 
Engine 1.7.7 and I'm getting the "Invocation of 
com.google.gwt.user.tools.WebAppCreator failed" error message. A quick 
browse offered up 3 solutions as below, each of which I have tried to no 
avail. 

1. Remove classpath - I don't have a classpath set
2. Add gwt-dev.jar & gwt-user.jar to classpath - tried this but it made no 
difference.
3. Workspace folder is read-only - opened up all permissions, but still no 
difference.

As expected from a quick read of the error message, removing GWT from the 
equation solves the problem, but I want GWT!

Also, unclicking "Generate sample code" solves the problem, but it leaves 
me with concerns that I'm going to come up against other problems down the 
road if this isn't configured properly.

Is there a solution to this, or should I just try and revert to the old 
versions of Eclipse, GWT etc., that I know (used) to work?
