Oy, now that is a different issue. You are using GAE? If you are developing GWT with no intentions of deploying to Google's App Engine servers, you should disable GAE option in Eclipse.
Otherwise, if you are developing for deploying on GAE, you have to realign your programming habits and attitude to use Google's data repository. Your deployed runtime is not allowed to create files on Google's servers. All your file outputs should be converted to data blobs and stored as repository objects. Then, in order for your users to get a "file" which you created, you need to have a reverse routine to access that data blob and stream it to the user. As the story goes, Google has put in a lot of investment to optimise their distributed data repository. So that someone in China (oops!) who uses your app and then simultaneously someone in Norway who also uses your app is able to access the data created by your app in a consistent manner. This is somewhat called distributed data technology and perhaps nowadays we could even call it cloudified distributed data. It does not make sense, at least to me, for Google to reinvestment another huge effort cloudifying a distributed file system. If you do not wish to go thro the tedium of writing your pseudo-file output stream to the data repository, you should consider Google App Engine Virtual File System http://code.google.com/p/gaevfs/.
