FOPException / Quiet Mode / error compliing servlets

["Xie, David (IPCG-NJ)" <xi...@exchange.ml.com>]

Thanks Jay and Jeremias for your help.  I need to convince people from work that FOP is our PDF solution.  However, without a good scalability test result (100% job completion rate), I am having
trouble doing so.  

I truely believe that one of the main reason for out of memory error is because FOP is running in debug mode, where you see every page gets generated (ex: page 1,2 [1][2]).  Most of the memory is used
by java to write debug information such as pages complete, initial and final heap size.. etc on to window's console.  If I can turn this off and run FOP in quiet mode, I am guessing the performance
would increase by at least 30% and scability will also improve.  

Jeremias, you sugguest to me to change edit the logger (http://xml.apache.org/fop/embedding.html).  how do I edit the code?  Do I need to get Avalon?

Jay, you mentioned that I might have to edit the FOP source code.  Do you know which java file I should edit so I can turn off the log screen?  Also, I am having trouble compling servlets.  Following
is the error message, can you tell me where I can get the SAX servlet package?  

thanks again for everyone's help.

David

Using a text editor. :-) Seriously, I guess you're using the fop.war in
docs/examples/embedding, right? The source code is in FopServlet.java.
Unfortunately, the WAR file is not built with the build script, so you
have to manually build the WAR file after adjusting the code. Actually,
it's not even necessary to build the WAR. It is sufficient to compile
FopServlet.java (you need to get servlet.jar from your web container to
do that) and place it (along with a web.xml file) in the right places.

And you don't need to get Avalon, since the necessary jars are in the
lib directory of FOP's distribution.

SAX has nothing to do with servlets. The SAX stuff is in xerces.jar. You
can get the servlet.jar from your web container or from here: 
http://java.sun.com/products/servlet/

To turn of logging you can also try to call
MessageHandler.setOutputMethod(MessageHandler.NONE);

Re: watermarking

[Guillaume Laforge <gl...@reflexe.fr>]

I've heard some people using FOP for generating PDFs, then using iText afterwards to add watermarking to their dynamically FOP-generated PDFs. But I havent tested it myself.

Good luck.

  hello all

  Is there any way of adding some kind of watermark to a PDF document generated with FOP ? I am using FOP in a JSP environment.

  Thanks
