Description

I have created a route which getting a messsage from a JMS queue and remove the header and match it with XSD then map it to the destination xml. But while i doing it in a flow it breaks in the mapping and getting the below error.
"Exhausted after delivery attempt: 1 caught: javax.xml.transform.TransformerException: java.lang.NullPointerException"
Please find my Route :
<from uri="jms:queue:INPUTQueue"/>
<log message="LOG : XML File received from input Queue:"/>
<log message="LOG : SOAP Header removel process Started:"/>
<to uri="xslt:src/main/resources/Header_Removel_XSL.xsl"/>
<log message="LOG : SOAP Header removel Completed: Validation process Started:"/>
<to uri="validator:xsds/schema.xsd"/>
<log message="LOG : Validation process Completed: Mapping Started"/>
<to uri="xslt:src/main/resources/Mapping.xsl"/>
<log message="LOG : Mapping Completed:"/>
<to uri="jms:queue:OUTPUTQueue"/>
<log message="Output Message : ${body}"/>

I have tested the Mapping.xsl alone and its wqorking fine. Please find the error below, Its a showstopper to us so kindly do the needful as ap.
