Subject Re: NPE for ${requestContext.brokerQuery.brokerAdmin.brokerName}
Date Thu, 25 Dec 2008 09:06:22 GMT
Hi,

as far as I can see from your configuration, you're missing
dispatcher-servlet.xml and webconsole-embedded.xml for starters. Take a look
at webapps/admin/WEB-INF/ folder of the ActiveMQ distribution for examples.

Cheers
