Description

Trying to convert 0.20.5 to fop-0.93-bin-jdk1.4.zip (1/3/2007). 0.20.5 worked
fine other than 'Out of Memory' exceptions. 0.93 generates the following error
when FopFactory.newInstance() is called during my PDFGenerator class's initial
PDFGenerator.getInstance():

Tried downloading from 2 different mirror sites. I'm using Eclipse 3.1.2 (with
MyEclipse Tomcat Server configuration). Configured Eclipse/MyEclipse to use
jdk 1.5.0_07 for Tomcat and Eclipse compiler, but Eclipse compiler is set to
compliance level 1.4.

FopFactory is private as in your Servlets Example although not in a servlet:
private FopFactory fopFactory = FopFactory.newInstance();
private TransformerFactory tFactory = TransformerFactory.newInstance();

Didn't install xalan, xercesImpl, xml-apis, or serializer jars (using jdk's xml
funcitonality instead), although that seems irrelevant for this.

Perhaps 0.93 isn't compatible with java 5.0? Seems like it should be - the
older 0.20.5 version works.

I hope I'm not overlooking something and that this is enough information.
