Re: [xsl] calling Java non static methods from XSLT

["Michael Müller-Hillebrand mmh@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Dr. Tapaal,

An often heard suggestion regarding performance is: Just test it.

It seems hard to me to send useful pointers based on this little information
and without any knowledge what the "complex algorithm" does and how the XSLT
is called ("each invocation of").

But, I would be very interested in your observations regarding the performance
calling a Java class over and over again (seemingly). Maybe you can share the
results of your tests and observations?

Thanks,

- Michael
