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.

Best regards,
Richard Trans

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

<xsl:variable name="xmlString">
        <xsl:copy-of select="/*[local-name()='Invoice']" />
</xsl:variable>

There is no need to copy it, just

<xsl:variable name="xmlString" select="/*[local-name()='Invoice']" />


f select="transf:rtrtransform(string($xmlString))"/>
                              ^^^^^^

the string function will throw away all the tree structure and just 
make
a string of the element contents. 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)
