Patch proposal

Hi,

When I have the code below in a servlet

	@Resource(mappedName="test")
	private DataSource ds;

'mapped name' is read when @Resource is processed (org.apache.catalina.startup.WebAnnotationSet.addResource(WebAnnotationSet.java:377)) so later on it is available through Reference object as StringRefAddr


But when I have the declaration below in web.xml

  <resource-ref>
  	<res-ref-name>datasource</res-ref-name>
  	<res-type>javax.sql.DataSource</res-type>
  	<mapped-name>test</mapped-name>
  </resource-ref>

'mapped name' is not read at all.

I would like to propose a patch that adds additional Rule to WebRuleSet so that 'mapped name' is process and set as property.

I'm looking forward to your comments.

Regards
Violeta Georgieva
