MIME_PDF missing from org.apache.fop.apps.MimeConstants

I am building a Java app that uses Apache FOP.

I downloaded the source from http://xmlgraphics.apache.org/fop/download.html

I tried creating an instance with
            Fop fop;
            fop = fopFactory.newFop(MimeConstants.MIME_PDF, out);

I received the error that MIME_PDF did not exist.

I neglected to include the xmlgraphics-commons jar that is in the build folder of the fop install.

These are the jar files I needed to include:

xmlgraphics-commons
avalon-framework
fop

Next, I received an error for any XSL files that used the ends-with xpath function. I needed two more jars from the fop build folder.

serializer
