Problem going from 4.0.6 to 4.1.16b
Hi All.
I'm hoping someone can shed some light on my problem. I'm trying to
upgrade from 4.0.6 to 4.1.16b and I'm finding that I'm unable to access
any JAR's in WEB-INF/lib. Here's what I'm getting from localhost_log:

I'm running Tomcat 4.1.16b on WinXP with JDK 1.4.1. I've attached a
copy of my server.xml file. My app works fine under Tomcat 4.0.6.
Does anyone have any ideas? Am I doing something wrong, or is there a
bug in Tomcat?
Thanks,
-Mark

Posted by Jacob Kjome <ho...@visi.com>.
Remove all XML/DOM libraries from WEB-INF/lib. They belong in a parent
classloader. This includes xalan.jar, xercesImpl.jar, and
xmlParserAPIs.jar. It violates the Sun classloading spec to load the XML
parser and W3C DOM libraries from a child classloader. They belong in
common/endorsed or common/lib.
See....
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=6374
<quote name="Remy Maucherat">
Yes, I know it doesn't happen with b2. There were other more insidious problems
with using a XML parser in a webapp repository (see 6248, and many messages on
tomcat-user).
It will force the XML base classes (and their subpackages, unfortunately,
that's
where the bug is) to be loaded from one of the parent shared classloader.
I've put a fix already in CVS in both branches (the base XML classes won't be
loaded to avoid the classcasts, but all the subpackages will). It is not
possible, and is actually forbidden by the servlet spec, to load those classes
from the webapp repositories.
LATER means that I'd like to implement a better mechanism to fully
implement the
spec requirements (although it will need some special configuration by the user
to define which libraries it has installed). This probably will stay in the
HEAD
branch, so the resolution of the bug may not be the right one.

I additon, this has some good explanation:

<quote name="Patrick Luby">
I agree with Remy that you should stop trying to override the default XML
parser.
While you *may* be able to override it when using JDK 1.3, you will absolutely
not be able to do it with JDK 1.4 as JDK 1.4 treats the XML parsing classes
(also
known as "endorsed" classes) as system classes. Hence, once the JVM is
started,
JDK 1.4 will not all any class loader in the process load alternate XML
parsing
classes that fall in any package names listed in the following URL:
http://java.sun.com/j2se/1.4/docs/guide/standards/index.html
The only way around this JDK 1.4 restriction for your webapp only is to
create an
XML parser with package names that are not listed in the above URL (i.e. a
very
non-standard parser).
There is another way around this restriction. However, it will force all
webapps
(and the container itself) to use your XML parser. You can put your parser jar
files in the common/lib directory (4.0.x) or in the common/endorsed directory
(HEAD).
