In additional: if I remove the xalan-2.4.1.jar  xercesImpl-2.1.0.jar  xml-apis.jar from Tomcat endorsed directory (like after the pure Tomcat installation)
I get the following error:

It is VERY strange behavior :(((

but all works fine if I copy into the Tomcat endorsed directory the  xalan  xercesImpl and  xml-apis libs from cocoon/lib
But xindice with some XPath expressions do not work correctly with xalan-2.5.1 &  xercesImpl-2.4.0 lib's (with xalan-2.4.1.jar  xercesImpl-2.1.0.jar all works fine)
May be still to early to include the xalan-2.5.1 &  xercesImpl-2.4.0 lib's into the cocoon project?

Can anyone say me where I'm wrong?
Thanks for all.
