Subject svn commit: r824680 - /forrest/branches/dispatcher_rewrite/plugins/org.apache.forrest.plugin.internal.dispatcher/src/java/org/apache/forrest/dispatcher/transformation/DispatcherTransformer.java

New Revision: 824680

URL: http://svn.apache.org/viewvc?rev=824680&view=rev
Log:
Enhancing error reporting.
When the result of the contract is returning an empty document the dispatcher reported a "com.ctc.wstx.exc.WstxEOFException:
Unexpected EOF in prolog". Now we catch this exception and reporting when this normally happens
(no forrest:container / forrest:part).
