Date Sun, 02 Oct 2011 00:58:33 GMT

    [ https://issues.apache.org/jira/browse/WW-3662?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13118940#comment-13118940
] 

Jason Pyeron commented on WW-3662:
----------------------------------

looking for comment on how to load container specific items

does adding urlHandlers to the short list sound justified? http://struts.apache.org/2.x/docs/webxml.html

        <init-param>
        	<description>The comma delimited list of url handlers to load first.</description>
        	<param-name>urlHandlers</param-name>
        	<param-value>org.apache.struts2.container.jboss.JBossURLHandler,com.foo.URLHandler,org.example.xyzzy.URLHandler</param-value>
       	</init-param>

it cannot be done through constants, since they are loaded by the url processing framework.

using the JDBC approach:
