> I use XSLTC in my own application running under JBoss (Win32/Linux) and Orion
> (Linux). When using the Java Extensions I get the following error:
> FEHLER: 'null'
> SCHWER WIEGENDER FEHLER: 'Die Formatvorlage konnte nicht kompiliert werden.'

> -> the style sheet I'm using stripped down to a minimum <-
> <?xml version="1.0" encoding="UTF-8"?>
> <xsl:stylesheet xmlns:java="http://xml.apache.org/xslt/java"; version="1.0"
> xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
>
> <xsl:param name="connection" />

> <xsl:param name="knrTable"

> 'LA.VERTRAEGE3', 'LA.VERTRAEGE3.PKN' )"/>
> <xsl:template match="/">
> <xsl:if test="string-length(string(java:get($knrTable, '0')))!=0 "/>
> </xsl:template>
>
> </xsl:stylesheet>
> <-------------------------------------------------------->
> If I switch back to Xalan everything works fine.
> The error above seems a bit missleading since if I remove the content of my
> template the error changes to:
> FEHLER: 'METHOD_NOT_FOUND_ERRcom.sqlgmbh.tcsap.xsl.LookupTable:new'
> I really can't see a possibility how this could be possible. The error
> remains even if I include the "missing" class directly in the xalan.jar file.
> Just a few more details:
> At startup the application loads a number of style sheets compiles them into
> Templates objects and stores them. Every once in a while the application has
> to transform XML data. To do so it loads an appropriate Templates object,
> generates a Transformer object, sets the "connection" param (data base
> connection) and executes the Transformer. This application has worked for
> years now so I guess it's not the problem.
> If you need further information please don't hesitate to ask!
