install problem with tomcat 5.5 on redhat

[Gaetano Giunta <gi...@gmail.com>]

Hello

I have been trying without success to install Solr on a RHES 5.1 server 
using Java 1.5.0.16 from sun, Tomcat 5.5.23 from the Red Hat repositories.
I tested both the solr version that comes packaged with the eZFind 
extension for eZPublish and the latest nightly.

The error that comes up in both cases is:
...
XPathFactory#newInstance() failed to create an XPathFactory for the 
default object model: http://java.sun.com/jaxp/xpath/dom with the 
XPathFactoryConfigurationException: 
javax.xml.xpath.XPathFactoryConfiguration

There is also an error when trying to access the application info page 
from the Tomcat admin application.

I read on a previous message in the mailing list that a possibly similar 
error was solved by repackageing xalan.jar into the solr war file. What 
version of xalan should be used for that? I have xalan installed in 
/usr/share/java, but it is possibly misnomed or not picked up by classpath.

Any hints?

Thanks
Gaetano
