Revision 195920

Servlet moved into normal source as package org.apache.fop.servlet.
Refactored FopServlet to use JAXP instead of XSLTInputHandler.
Improved code to serve as educational example.
FopPrintServlet compiles but doesn't work because no AWT renderer is currently available.
FopServlet works fine here but currently only support filenames as input parameters. Should be improved.
