Re: conflict between jaxp.jar, parser.jar (tomcat lib) and xalan.jar, xerces.jar?

[Antony Bowesman <ad...@teamware.com>]

JAXP shipped with tc3 is 1.0.  If this jar gets on the classpath before
xerces then it won't work.  Either removing jaxp or updating it to 1.1
will solve the problem.

Are you suggesting that the jars are loaded in alphabetical order? I
would
have said you should either move parser.jar to the end of the class path
or
remove it entirely since xerces.jar contains the necessary jaxp
interfaces.
Tomcat 3.2 does not access the parser directly but through jaxp so you
can
safely remove parser.jar and jaxp.jar and use only xerces.jar.

The problem is with the order the jars are loaded. There is a version
confilict with some classes.
A common workaround is to rename parser.jar into zparser.jar, so it is
loaded after xalan.jar and xerces.jar.
 
This worked for me.

Hi --
 
I'm running a servlet application that uses the apache-XML   xalan.jar
and
xerces.jar files for handling XML/XSL stuff.
 
With tomcat 3.2.1,  when I run my servlet,  I get  NoSuchMethodError on
 
     getNamespaceURI(),  called by
org.apache.xpath.DOM2Helper.getNamespaceOfNode().
 
I solved this problem by removing the jaxp.jar and parser.jar files that
come with the tomcat installation and sit under 
the lib directory.
 
The servlet still runs without those jar files, so the xalan.jar and
xerces.jar must do the trick.
 
Is there some kind of version conflict that causes the
NoSuchMethodError?
 
Thanks
 
Betty
