Subject [jira] Commented: (AXIS2-4673) kernel TransportUtils.createSOAPEnvelope should return empty envelope for empty InputStream
Date Thu, 08 Apr 2010 10:04:37 GMT

    [ https://issues.apache.org/jira/browse/AXIS2-4673?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12854883#action_12854883
] 

Andreas Veithen commented on AXIS2-4673:
----------------------------------------

I agree with Rich. Since TransportUtils.createSOAPEnvelope is used by most of the transports
and an empty payload is invalid in that context (unless the message builder decides otherwise),
we should not introduce hacks to work around specific problems in Sandesha.

> Currently, the org.apache.axis2.transport.TransportUtils.createSOAPMessage correctly
throws an exception for a null InputStream, but passes an empty InputStream down to the parser,
which may throw an exception resulting in an exception stack similar to:
> Throwable occurred: org.apache.axiom.om.OMException: javax.xml.stream.XMLStreamException:
The root element is required in a well-formed document.
