Version compatability for Transformation

Question

Hi,
I developed code for transforming the xmls by using xsl contain java methods
ex:
<xsl:stylesheet version="2.0" xmlns:jiva="com.seq.sqlxml.xslutil" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" exclude-result-prefixes="seq" >
<xsl:output method="xml" indent="yes" encoding="utf-8"/>
<xsl:param name="SEQXML"/>
<xsl:template match="/">
<ROOT>
<xsl:attribute name="mapping-schema"><xsl:value-of select="seq:getMappingSchemaName($SEQXML)"/></xsl:attribute>
<Cart relation="Cart" >
<xsl:for-each select="pageXML/Cart" >
<CartId> <xsl:value-of select="seq:getContextSequence($SEQXML, ./CartId, 'Cart_Sequence')" /> </CartId>
</xsl:template>
</ROOT>
Here getContextSequence(int cartId,String CartSequence) is java function
My problem is
StreamSource stylesource = new StreamSource(new File(xSLFile));
Transformer transformer = TransformerFactory.newInstance().newTransformer(stylesource);
This code is working well for j2sdk 1.4 but it raises the Exception in JDK1.5
Exception:
ERROR: 'The first argument to the non-static Java function 'getMappingSchemaName' is not a valid object reference.'
FATAL ERROR: 'Could not compile stylesheet'
javax.xml.transform.TransformerConfigurationException: Could not compile stylesheet
     at com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl.newTemplates(TransformerFactoryImpl.java:824)
     at com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl.newTransformer(TransformerFactoryImpl.java:619)
So please help to over come this problem.
Thanks & regards

TigerYou get that error because you are trying to invoke a method in the wrong object reference. I suspect your passed in parameter $SEQXML is not a
com.seq.sqlxml.xslutil object instance.
First make sure the method you are trying to invoke has the right signature. Second, if the method is not a static method, then make sure the object parameter you passed in is the correct instance.
