Re: [Resteasy-users] ClassCastException help.

  Hi Sean,

You need to add your Application class as a web archive context param in 
web.xml. For example:

<context-param>
<param-name>javax.ws.rs.core.Application</param-name>
<param-value>org.jboss.jbossts.rts.service.TMApplication</param-value>
</context-param>

The servlet class should reference Bills' implementation as in:

<servlet>
<servlet-name>Resteasy</servlet-name>
<servlet-class>org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher</servlet-class>
</servlet>
