Hi,

I have written a simple script to read in an xml file from the command line and 
convert it to pdf. I have put the script in the FOP/source/fop-0.20.4/src 
directory. When I run the build script, it compiles okay. However, when I try 
and run the compiled code it gives me the following error:

test:ozhan 510% java RenderingEngine input.xml output.pdf
Exception in thread "main" java.lang.NoClassDefFoundError: 
org/xml/sax/SAXException
        at RenderingEngine.main(Unknown Source)

It appears that the sax library isn't present in my source tree. The code is 
shown below:
