I will test it till I am stupid.

In a web application a parent classloader has precedence over a child
classloader. This means that if you put a library into WEB-INF/lib and
it is already available in one of the parent classloaders (e.g. the
container classloader or the JVM application classloader), the latter
will be used.
The shielding classloader reverses this hierarchy. If it doesn't work
you might run into a bug :-(

Yeah you are right. I copied the xml api and xalan jars from the
web-inf/lib into the edorsed dir of tomcat, and it works.
The shielded class loading did not what I expected. I set it to true
and false, but in both cases the same old error appears. Is the
shielded class loading the only mechanism by which I can make sure,
that Tomcat calls the newer jars from my webapp?

Hello everybody,
My Webapp grows. :) Thank you all for all your help till now.
The next thing I am struggeling with is this:
Error creating bean with name 'de.memocomp.myBlock1.service':
Invocation of init method failed; nested exception is
java.lang.NoSuchMethodError:
This error appears only in Tomcat 5.0 with JRE 1.4. Everything
works with Tomact 5.5 and JDK 1.5.
I managed to create a war file completely with JDK 1.4 as
JAVA_HOME. The manifest file looks good. Only Tomcat doesn't want
to start the webapp. Any suggestions?
My guess is that you have a problem with your XML parser.
[uuups, the mail went out too fast.]
Make sure that you use a new(er) version of Xerces and Xalan. With
JDK 1.4 you have to set the endorsed-lib directory correctly.
Another option is using the shielding classloader by utilizing the
Cocoon Maven plugin to build the web application:
http://cocoon.apache.org/2.2/maven-plugins/maven-plugin/1.0/1262_1_1.html
and
http://cocoon.apache.org/2.2/maven-plugins/maven-plugin/1.0/deploy-mojo.html
