RE: [xsl] EXSLT user-defined function question

["Sanjeeb Basak" <sbasak@xxxxxxxxx>]

Hi Geert,

I'm actually trying to implement the exslt function by xslt, and not by
java code. I'm wondering if I'm doing some small mistake in the syntax
of the xslt function implementation, calling of it from the main xslt
code, the relevant  namespaces, etc.. i'm also trying the exslt function
the first time :-)

Thanks
Sanjeeb

Hi Sanjeeb,

I haven't added functions myself, but the most obvious question is: have
you given you java class the proper package name and have you added it
to the CLASSPATH of the jvm instance?

Grtz,
Geert
