Yes, it extends org.apache.xpath.functions.Function. I managed to get
it function properly (a lot of tweaking in the definition files xpath/
compiler/) and the only hurdle now is to convert your function to an
Xalan 2.7.0 function. I'll be back at work on thursday so I'll let
you know what comes out.

Jeroen,
although the method
org.apache.xpath.compiler.Functiontable.installFunction
(String name, Class func) has an array with the name
m_functions_customer,
I don't think this is a public API. It may be public in the Java
sense, but
that is probably due to it being using in a different package.
That said, from what I can see from another method in Functiontable
used
later on to retrieve the XPath functions, that the Class passed in
must
directly or indirectly extend org.apache.xpath.functions.Function:
Function getFunction(int which)
throws javax.xml.transform.TransformerException
{
try{
if (which < NUM_BUILT_IN_FUNCS)
return (Function) m_functions[which].newInstance();
else
return (Function) m_functions_customer[
which-NUM_BUILT_IN_FUNCS].newInstance();
}catch (IllegalAccessException ex){
throw new TransformerException(ex.getMessage());
}catch (InstantiationException ex){
throw new TransformerException(ex.getMessage());
}
}
Is your class extending org.apache.xpath.functions.Function?

Adding an XPath Function in
Xalan
2.7.0
Hi,
I'm trying to add an XPath function to Xalan 2.7.0. The function
itself
compiled without any problems but using
org.apache.xpath.compiler.Functiontable.installFunction yields
errors I
can't come by.
Is the installFunction usable at the moment and if so, can anyone
please
supply me with a small example of the call?
Thanks in advance.
