java - Is it somehow possible to create image files from GWT charts on google app engine? -


i'd need app runs on google app engine able automatically create image files gwt graphics on server later automatically attached in email automatically sent once week.

but far i've investigated see no possible way on server, first off, haven't been able use imagecharts on google appengine had use columncharts , linecharts, complicate process turn images, althoug think done although take while, although maybe impossible it.

biggest problem see google app engine has file i/o absolutely banned, although there might workaround, guess it's difficult one, know blobstore, i've seen allows upload existing files own pc, not create new ones.

is there done?
