I'm having trouble combining two Cocoon samples into the same mapping.
I setup this simple mapping using the Stream and POI examples in Cocoon
2.0.4:
<map:match pattern="convert">
<map:generate type="stream"/>
<map:serialize type="xls"/>
</map:match>
When I fill the Stream example's form (OrderPage.xml modified to
action=convert), with the content from the POI's sample
(hypothetical-sales.xml) and POST it, I get:
type fatal
message Exception in StreamGenerator.generate()
description org.apache.cocoon.ProcessingException: Exception in
StreamGenerator.generate(): java.lang.NullPointerException
sender org.apache.cocoon.servlet.CocoonServlet
source Cocoon servlet
stack-trace
org.apache.cocoon.ProcessingException: Exception in
StreamGenerator.generate(): java.lang.NullPointerException

entPipeline.java:250)
at
org.apache.cocoon.components.pipeline.CachingStreamPipeline.process(CachingS
treamPipeline.java:395)
I was of course hoping that the POSTed XML from hypothetical-sales.xml would
be serialized into XLS and fed back to me as the response. Can anyone
explain why I receive the NullPointer, and/or help me achieve my desired
result?
Thanks,
