Xalan, Resolver classes, ~/lib/endorsed, default version org.apache.xalan.xslt.Process ?, override it? URIResolver class not found

[Steve Whitlatch <swhitlat@getnet.net>]

I just downloaded and installed Xalan Java version 2.5.2, but for some 
reason Java always uses Xalan version 2.4.1. 

%java org.apache.xalan.processor.XSLProcessorVersion
Xalan Java 2.4.1

That's bad because Xalan Java version 2.4.1 is known to have problems 
accessing the Resolver classes, which is the reason I upgraded Xalan.

I'm trying to get Xalan Java to use either the Sun Resolver classes or 
the Apache Resolver classes, doesn't matter which. Saxon finds both 
and uses either with no trouble. But Xalan Java always issues the 
same error message:
Class file not found for option -URIResolver

I think this is the problem described in the bug report at:
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=17030
I see that bug report's STATUS=RESOLVED and the RESOLUTION=FIXED and 
the bug report has been marked as CLOSED. Trusting that this bug has 
actually been fixed, it would seem that if I were using an Xalan 
version > 2.4.1, then this bug would not be biting me. But it seems I 
cannot get java to use anything but the 2.4.1 version of Xalan.

If I read the bug report correctly, the cause of Xalan not being able 
to load the Resolver classes was that Sun included an older version 
of Xalan (version 2.4.1) in the jre's ~/lib/endorsed directory. So, I 
downloaded Xalan Java 2.5.2, replaced the version in ~/lib/endorsed 
with the new one, put a copy version of xalan.jar version 2.5.2 in /
usr/local/j2ee_1.4/jdk/jre/lib/ext/, and even put another copy of 
xalan.jar version 2.5.2 in my personal bin directory and included it 
in my CLASSPATH. So, the new 2.5.2 version should have replaced the 
2.4.1 version. Correct? Nope, not yet.

No matter what xalan.jar file I try to use, java uses a 2.4.1 version, 
the whereabouts of which I have not yet determined. 

%java org.apache.xalan.processor.XSLProcessorVersion
Xalan Java 2.4.1

And that's with all those Xalan Java 2.5.2 versions I just installed.

I can do "locate xalan.jar" to find all files with that name anywhere 
on this computer. I did and replaced those that appeared to possibly 
be used by the JVM. Still, it is all 2.4.1.

java org.apache.xalan.xslt.Process -V
>>>>>>> Xalan Version Xalan Java 2.4.1, <<<<<<<

%java -version
java version "1.4.2_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_02-b03)
Java HotSpot(TM) Client VM (build 1.4.2_02-b03, mixed mode)

Please advise if you can.

Thanks,
