XSL transformation never works on Websphere 5

Question

I'm doing a xsl transformation on websphere 5 and this xsl never finds the right values. When I run the exact same transformation with the same source, it finds all the values, but on the server it just return empty tags. Why? And how do I fix this?
Source xml:
<?xml version="1.0" encoding="ISO-8859-1"?>
<n:OrderResponseComplex xmlns:n="http://sirius/xml/common">
     <n:AcceptedIndicator>Akseptert</n:AcceptedIndicator>
     <n:RejectionReasonCode>0</n:RejectionReasonCode>
</n:OrderResponseComplex>XSL transformation:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0" xmlns:xalan="http://xml.apache.org/xslt">
     <xsl:template match="/">
          <SiebelMessage IntObjectFormat="Siebel Hierarchical" IntObjectName="TBS2 OHS Reply" MessageType="Integration Object">
               <TBS2OHSReply>
                    <OrderEntry-Orders>
                         <BackOfficeErrorText><xsl:value-of select="OrderResponseComplex/RejectionReasonCode"/></BackOfficeErrorText>
                         <Status><xsl:value-of select="OrderResponseComplex/AcceptedIndicator"/></Status>
                    </OrderEntry-Orders>
               </TBS2OHSReply>
          </SiebelMessage>
     </xsl:template>
</xsl:stylesheet>Result xml:
<?xml version="1.0" encoding="UTF-8"?>
<SiebelMessage MessageType="Integration Object" IntObjectName="TBS2 OHS Reply" IntObjectFormat="Siebel Hierarchical">
     <TBS2OHSReply>
          <OrderEntry-Orders>
               <BackOfficeErrorText/>
               <Status/>
          </OrderEntry-Orders>

Answer 1

You need to watch out for the namespace in the source document:
You can either specify the namespace and use it when locating paths in the source document (as below) or specify it as the default namespace.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
     xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
     version="1.0"
     xmlns:xalan="http://xml.apache.org/xslt"
     xmlns:n="http://sirius/xml/common">
<xsl:template match="/">          
     <SiebelMessage IntObjectFormat="Siebel Hierarchical" IntObjectName="TBS2 OHS Reply" MessageType="Integration Object">
          <TBS2OHSReply>                    
               <OrderEntry-Orders>                         
                    <BackOfficeErrorText><xsl:value-of select="n:OrderResponseComplex/n:RejectionReasonCode"/></BackOfficeErrorText>
                    <Status><xsl:value-of select="n:OrderResponseComplex/n:AcceptedIndicator"/></Status>
               </OrderEntry-Orders>
          </TBS2OHSReply>
     </SiebelMessage>
</xsl:template>
</xsl:stylesheet>
