Re: SAX, fopservlet and 0.20.2
J: Thanks - that clarifies it. The newer xalan did and, with the upgrade to the newer fop and the namespace fix, it is now working (although I had to rename my servlet from fop to fop.pdf to get the pdf output in IE). I now have to work on performance - my users don't like waiting 30min to and hour for their pdf reports.

Re: SAX, fopservlet and 0.20.2
OK, I take back some of what I previously said. I upgraded my xalan to 2.3.1 and that fixed the NPE when transforming the glossary example. I still consistently get the NPE on my own files from the servlet, but now I also get it from the command line. Being at a loss, per the xalan 2.3.1 instructions, I switched my xerces jar to xercesImpl.jar, but now I get the following: org.xml.sax.SAXParseException: The prefix fo for element fo:external-graphic is not bound. I am still using 0.20.2 fop so I am pretty confused on which jars I should be using. Anyone have any ideas? What jars should be in my path? -Lou [EMAIL PROTECTED] on 06/06/2002 07:51:09 Please respond to [EMAIL PROTECTED] To: [EMAIL PROTECTED] cc: Subject: Re: SAX, fopservlet and 0.20.2 J: Thanks for the response.

Re: SAX, fopservlet and 0.20.2
OK, I thawed the jar files and upgraded to 20.3 (and rolled back my xalan and xerces changes) and that seems to do the trick. The fo issue was a bug in an included stylesheet that I fixed. -Lou [EMAIL PROTECTED] on 06/06/2002 11:50:26 Please respond to [EMAIL PROTECTED] To: [EMAIL PROTECTED] cc: Subject: Re: SAX, fopservlet and 0.20.2 OK, I take back some of what I previously said.

Jeremias Maerki [EMAIL PROTECTED] wrote: The only place where Xerces is directly imported is the PFMReader and TTFReader. Ok, Driver, when startet using the command line, uses Xerces by default, but nothing prevents you from using any JAXP parser with FOP. Stuff matching org.apache.x* in 0.20.2: ...Driver.java parserClassName = org.apache.xerces.parsers.SAXParser; ...PFMReader.java org.apache.xerces.dom.*; org.apache.xml.serialize.*; org.apache.xalan.xslt.*; ...TTFReader.java dto. ...fop.layout.hyphenation.PatternParser.java parserClassName = org.apache.xerces.parsers.SAXParser; ...fop.tools.anttasks.CompileXMLFiles.java parserClassName = org.apache.xerces.parsers.SAXParser; ...fop.tools.xslt.Xalan1Transform.java org.apache.xalan.xslt.*; ...fop.tools.xslt.XSLTransform.java Class.forName(org.apache.xalan.xslt.XSLTProcessor); I believe all this stuff could be replaced by JAXP 1.1 standard functionality. This means FOP could also be build with any JAXP 1.1 compatible XML/XSL library. This would also get rid of some unfortunate dependencies from Driver.getParserClassName() (why not use SAXParserFactory.newSAXParser().getXMLReader() instead and let the library handle all the annoying stuff? At the same time, validation could be switched off, gaining some performance in rare cases). I could try to prepare patches, however: - Is there a chance to get them into the maintenance branch? (there is a feature freeze pending, AFAIK) - Last time i tried i was not able to build FOP successfully, because of an odd ant incompatibility problem i didn't (and still don't) have time to resolve. This means i can only try basic compilation, someone else would have to finalize the patch.
