Hi,
I am trying to pass XML as an input parameter the JAVA trannsformer but am
getting the following error :
Exception stack is:
1. Invalid conversion from 'org.apache.xerces.dom.DeferredElementImpl' to
'node-
set'. (java.lang.RuntimeException)
com.sun.org.apache.xalan.internal.xsltc.runtime.BasisLibrary:-1
(http://java.sun.com/j2se/1.5.0/docs/api/java/lang/RuntimeException.html)
Root Exception stack trace:
java.lang.RuntimeException: Invalid conversion from
'org.apache.xerces.dom.DeferredElementImpl' to 'node-set'.

Input XML :
<?xml version="1.0" encoding="UTF-8"?>
<order>
<clientId>CLT001</clientId>
<orderId>ORD001</orderId>
<bill>12.5</bill>
<deliveryDate>2006-01-11</deliveryDate>
<location>001</location>
</order>
Input Parameter to the stylesheet (also an XML) :
<?xml version="1.0" encoding="UTF-8"?>
<locations>
<location>
<name>001</name>
<value>Bangalore</value>
</location>
<location>
<name>002</name>
<value>Dellhi</value>
</location>
</locations>
Stylesheet:
<?xml version="1.0" encoding="ISO-8859-1"?>
<?altova_samplexml C:\Documents and Settings\gaurav_suri\Desktop\Input.xml?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" encoding="ISO-8859-1"
standalone="yes"/>
<xsl:template match="*">
<client>
<xsl:value-of select="clientId"/>
</client>
<ordernumber>
<xsl:value-of select="orderId"/>
</ordernumber>
<deliverydate>
<xsl:value-of select="deliveryDate"/>
</deliverydate>
<bill>
<xsl:value-of select="bill"/>
</bill>
<area>
<xsl:value-of
select="$ORM/locations/location[name=001]/value"/>
</area>
</xsl:template>
</xsl:stylesheet>
Code Snippet :
Source sourceDoc = getXmlSource(src);
if (sourceDoc == null) return null;
ResultHolder holder = getResultHolder(returnClass);
if (holder == null) holder = getResultHolder(src.getClass());
DefaultErrorListener errorListener = new
DefaultErrorListener(this);
Transformer transformer = null;
Object result;
try
{
transformer = (Transformer)transformerPool.borrowObject();
transformer.setErrorListener(errorListener);
transformer.setOutputProperty(OutputKeys.ENCODING,
encoding);
//set transformation parameters
if (transformParameters != null){
for(Entry<String,Object> parameter :
transformParameters.entrySet()){
transformer.setParameter(parameter.getKey(),
evaluateTransformParameter(parameter.getKey(),parameter.getValue()));
}
}
transformer.transform(sourceDoc, holder.getResult());
result = holder.getResultObject();
//where evaluateTransformParameter method returns a document built as
follows :
DocumentBuilderFactory documentbuilderfactory =
DocumentBuilderFactory.newInstance();
InputSource inputsource = new InputSource(new StringReader(s));
org.w3c.dom.Document document =
documentbuilderfactory.newDocumentBuilder().parse(inputsource);
return document;
//s being the input XML parameter as string.
Any pointers for correction..
Regards
Gaurav
