RE: errors in installation - oops

[Jesse Reynolds <li...@va.com.au>]

Doh, stupid me. It is too in the FAQ. (Indeed it looks like my 
question is one of the most popular on this list :-)

If you're using Tomcat 3.2.1 and Cocoon 1.8, the answer is to rename 
$TOMCAT_HOME/lib/parser.jar to z-parser.jar (so it comes after 
xerces.jar in the automatically generated CLASSPATH) ... but there's 
a better explanation in the FAQ:

Q: I get a java.lang.NoSuchMethodError at XSPJavaPreprocessor. What's wrong?

A: This happens because Cocoon needs a DOM Level 2 implementation and 
you probably have a DOM Level 1 included in your classpath before 
xerces.jar.

So, place the xerces.jar archive that comes with Cocoon before all 
the other jar packages in your classpath.

Some servlet engines, such as Tomcat, construct a CLASSPATH 
automatically based on all the jar files in a lib directory. In this 
case, you may need to rename the jar file containing the DOM Level 1 
(xml.jar or parser.jar) to something like zzz.jar to force it to come 
last, or even move it out of the lib directory altogether.

If even that doesn't work, also check that there is no XML parser in 
your JDK's lib/ext or jre/lib/ext directories. If there is, remove it.

Unfortunately, some servlet engines require DOM Level 1 to be ahead 
of DOM Level 2 in the CLASSPATH - conflicting with Cocoon! There is 
no known workaround for this problem (but see the next question) - 
please let us know at cocoon-users@xml.apache.org if you find one.

cheers
