call to extension element failed:

This the issue when i try to transform the XML shown below using the XSL
shown below. The error message that i get is here. Actually i'm trying to
use JavaScript functions in the XSL. I've also included bsf.jar; js.jar;
bsfengines.jar in the classpath.
This is the sample given at the Apache.org site. I would appreciate if
somebody gives me some assistance.

The correct namespace is

  xmlns:lxslt="http://xml.apache.org/xslt
