I think you are asking if JMesa could be used as a generic library to create 
PDF's, Excel Worksheets, etc...?

Its an interesting question and technically I like the idea. Not sure it would 
be worth it in general as JMesa was created to be a web framework.

I basically got it working by extending a few classes of JMesa. Now, my code
can be used for
1. display on page
2. export to file on the fly
3. export to file by a background job
