Embedding FOP within Servlet

[Georg Daniel Vassilopulos <a...@viot.de>]

Hello All,

With the example "embedding" distributed with fop-0.20.3-src.tar.gz I got stuck.

The PDF generation from a *.fo file works fine. But while generating 
a PDF out of a xml file and a xsl stylesheet I always get the exception:

org.apache.fop.apps.FOPException: javax.xml.transform.Transformer
	at org.apache.fop.apps.XSLTInputHandler.getParser(XSLTInputHandler.java:107)
	at FopServlet.renderXML(FopServlet.java:118)
	at FopServlet.doGet(FopServlet.java:67)
	at javax.servlet.http.HttpServlet.service(HttpServlet.java:740)


I have following jar files in my tomcat/webapps/WEB_INF/lib directory and the logiles report
that following jar file were found (yes I did put them there):

ant.jar
ant-1.3-optional.jar
avalon-framework-4.0.jar
batik.jar
bsf.jar
buildtools.jar
fop.jar
logkit-1.0.jar
stylebook.jar
xalan-2.0.0.jar
xerces-1.2.3.jar


I thougt the Transformer class ships with xalan-2.0.0.jar but anyway, I get the exception.

Any help would be great. 

Thanks a lot...
Georg

That's a classloader issue. I haven't investigated what exactly the
problem is, but putting xalan.jar in common/lib or lib instead of
WEB-INF/lib should do the trick.
