Firstly note that this changes in Saxon 9.2. With 9.2, picking up Java
methods from the classpath ("reflexive extension functions") is not
supported in Saxon-HE: you need Saxon-PE or Saxon-EE.
Other than that: use the -TJ flag on the command line for extra diagnostics.
This will explain where the software is looking for the extension function
which may help to explain why it wasn't found.

Subject: [xsl] calling java methods from a stylesheet
Hi there,
i have some stylesheets which were written to be processed by
the xalan processor. Now I want to switch to saxon. These
stylesheets contain java methods that should be executed.
Therefore they include the following namespace
"xmlns:java="http://xml.apache.org/xslt/java";. The .jar file
which holds the java classes is included in the classpath. A
method call looks like the following:
<xsl:value-of
select="java:de.novum.vger.util.DateUtil.getTodayString()" />
which works fine with xalan.
How can I make these stylesheets work with saxon without
changing too much?
I thought it would work like this:
add namespace: xmlns:java="java:de.novum.vger.util.DateUtil"
call method:
<xsl:value-of select="java:getTodayString()" />
but I get the following error:
Error at xsl:value-of on line 40 column 84 of
stylesheet_leistungsfall_variabel_dta.xsl
XPST0017: XPath syntax error at char 21 on line 40 in
{java:getTodayString()}:
Cannot find a matching 0-argument function named
{java:de.novum.vger.util.DateUtil}getTodayString()
Why does saxon not find the class, although the jar-file
containing it is in the classpath?
regards,
Garvin
