Re: [xsl] Calling java from xsl - with xml as parameter

Hi David. Your answer brought me closer. Knowing datatypes is important. If i do as you suggested: <xsl:variable name="xmlString" select="/*[local-name()='Invoice']" /> and: <xsl:variable name="pdfBytes"> <xsl:value-of select="transf:rtrtransform($xmlString)"/> </xsl:variable> then it sends a NodeSet (I THINK) to the java method. But the java method does not get called. I get an error: javax.xml.transform.TransformerException: java.lang. NoSuchMethodException: For extension function, could not find method dk. edbgruppen.genericdocumentprocess.transformation.TransformManagerImpl. rtrtransform([ExpressionContext,] #NODESET). Checked both static and instance methods. Is one of my datatypes wrong? public static String rtrtransform(NodeSet object2Transform) { try { //method is simplified. System.out.println("OK " + ""); return "ok"; } catch (Exception ex) { System.out.println("Error " + ""); return "Error"; } } I know i didnt send complete files, but i think you understand the problem.

If you don't want that, just pass the xml to your extension functrion, assuming your function can accept XML nodes (using some object model) David ________________________________________________________________________ The Numerical Algorithms Group Ltd is a company registered in England and Wales with company number 1249803.
