After deploy dubbo-admin-2.5.4.war into EAP 6.4, the html page didn't display correctly.

Issue

Dubbo is a distributed, high performance RPC framework created by Alibaba, it can be deployed on Tomcat, JBoss, ect.
Customer found dubbo-admin-2.5.4.war can be deployed in EAP 6.4, however when visit http://127.0.0.1:8080/dubbo-admin-2.5.4/, the page lost format and pics just remains links and text, the page source shows:

<link type="text/css" href="$rootContextPath.getURI("css/comm.css")" rel="stylesheet" />

The correct code should be:

<link type="text/css" href="/dubbo-admin-2.5.4/css/comm.css" rel="stylesheet" />

And this war works fine in Tomcat.
