svn commit: r608985 [1/2] - in /webservices/axis2/trunk/java/modules/jaxws:

New Revision: 608985
URL: http://svn.apache.org/viewvc?rev=608985&view=rev
Log:
AXIS2-3417
Contributor:Rich Scheuerle
Added shortcut code to the JAXWS Block implementation to get the business object
from the DataSource.
For example, if the OMElement has a backing JAXBDataSource, then the JAXBBlock can
retrieve the JAXB object (and JAXBContext) directly from the data source.
I also added a unit test to BlockTests.java to verify the new code.
