RE: Performance Problem Question: Web Container (Tomca

George:

You are right, I get as XSL Vendor Apache Software Foundation running in
tomcat and on console I get SAXON 6.5.3 from Michael Kay.

Any hints how to change to the right XSL vendor?  Is this a path problem
or do I have to set something specific?

vs. Console excecution

Hi Andreas,

There may be two possible problems:
- you are not using Saxon but the Xalan that comes with Java 1.4+.
You can output <xsl:value-of select="system-property('xsl:vendor')"/>
from your stylesheet to see what processor is used.
- the time difference is in the network transfer and not in the XSLT
processing.

Best Regards,
George
