[appengine-java] Re: PDF Files
Hi: You can't let GAE/J Blobstore API serve the blob for you. You have to read the blob content and serve by yourself. This approach reduces to normal/regular pdf file download which is trivial.

[appengine-java] Re: PDF Files
The patch seems to be incompatible with IText license, as you can read in comments at http://sourceforge.net/tracker/?func=detailaid=2810312group_id=15255atid=365255 PDFJet has both a free limited version and a paid one, which adds functions like tables formatting and pagination. I used the free version succesfully for simple tasks. It lacks complexity (like handling layout) but you can use the basic API to build such advanced features. Looks like IText can work on GAE also without the patch if you limit the functionalities you use. Such limitations make IText very similar to PDFJet with respect to API flexibility and level of abstraction, since advanced Itext features are the ones using AWT, so I decided to go directly with PDFJet for my project.
