Description Dan Clancy 2009-07-08 04:36:41 UTC 
The Apache POI jar (poi-3.2-FINAL-20081019.jar) has incompatibilities with Google App Engine because it uses various Java classes (java.awt.Color etc.) which are not allowed within the Google App Engine environment.

Unfortunately, those awt references aren't just there for fun - we really do need them. Without it, we can't do font stuff, can't do column resizing, we can't read/change the colour of text, can't do any in-excel drawing related stuff etc. The needs for awt are quite wide ranging across the library.

I think you'll need to find yourself an awt compatibility jar that provides those classes, then load that in there too.
