Are you failing an FOP transform?
Can you provide xml/xslt or fo to test?
 
I use 7-Zip to view jars.  Open your jars and look for the manifest
file.  Verify they don't have a classpath line, or make note of what
jars they refer to.
FOP has, or had in a previous version, a classpath in it's manifest.  I
found a couple of jars it requires which also had one and I downloaded
their source and removed it to recompile since we set up our classpaths
differently.
 
Web addresses in xslt do not require web access.  I wondered about that
when I was learning it as well.

Hi,

 

I see from the FOP site that "When using a servlet engine, there are
potential CLASSPATH issues, and potential conflicts with existing
XML/XSLT libraries. Servlet containers also often use their own
classloaders for loading webapps, which can cause bugs and security
problems."

 

The other thing that it could be is our test environment doesn't have
access to the Internet. The URI namespace is
"http://www.w3.org/1999/XSL/Format"; I understand that the namespace URI
strings are simply unique identifiers not valid URLs so I don't think
this would cause the application to fail.

 

Based on these possible causes, is there any information on the XML/XSLT
libraries that can be in conflict with FOP or do I need to have internet
access to transform the document.

 

One thing I have noticed when I do the following:

 

 FOElementMapping fem = new FOElementMapping();

 String namespaceURI = fem.getNamespaceURI();

 ElementMappingRegistry emr = new ElementMappingRegistry(fopFactory);

 String elementMapping = emr.getElementMapping(namespaceURI));

 

The elementMapping is null in my remote test environment and is set to
an instance of an object org.apache.fop.fo.foelementmapp...@57306c on my
local JBoss version. 

 

 

Best Regards, 

John

Re: [Barcode4j-users] barcode4j question

2010-12-07 Thread Jeremias Maerki

John,
I still think this is a class loading problem. You didn't say what kind
of server you're using. If, for some reasons, that server unpacks all
application JARs into a commons local directory and loads the classes
from there, it could possibily be so that Barcode4J's
META-INF/services/org.apache.fop.fo.ElementMapping file overwrote the
FOP one. That way, FOP doesn't find its own fo:* classes and that
UnknownXMLObj might be explained. You could try to temporarily remove
the Barcode4J FOP extension from the classpath and check if that changes
anything.

At any rate, you have to make sure the individual JARs are not merged
without special handling for the META-INF/services files and that all of
the JARs are associated with the same classloader(-hierarchy).

RE: [Barcode4j-users] barcode4j question

2010-12-06 Thread John Brady

Hi,

I have taken a clean version of fop.jar (FOP 0.95) from here:
http://archive.apache.org/dist/xmlgraphics/fop/binaries/

I am still getting the same issue (error attached). It is throwing the error at 
the following call (method attached):

transformer.transform(src, res);

I am able to get it to work in eclipse under test conditions but when I deploy 
it to my UAT server it fail at the line above. I am thinking that I am missing 
a jar on UAT that eclipse may have included. Do you know what else could cause 
this issue?

John Brady

Hi John

This smells like a class loading problem. I'd say that FOP
hasn't found the file META-INF/services/org.apache.fop.fo.ElementMapping
in the classpath. That usually doesn't happen. I can only imagine that
you've unpacked fop.jar and repacked it in a different way so the
plug-ins are not found. After all, the main ElementMapping services file
is normally (!) in the same JAR as the ElementMappingRegistry.
