Haven't done this myself but did you create a parameter with  HashMap datatype and created scriplets to process the parameter?

I added parameter in jrxml but how to iterate those parameter in jrxml?

 <parameter name="severity" class="java.util.ArrayList"></parameter><parameter name="messages" class="java.util.ArrayList"></parameter>//In textField added:<textFieldExpression><![CDATA[$F{severity}]]></textFieldExpression><textFieldExpression><![CDATA[$F{messages}]]></textFieldExpression>[/code]
