如何为特定资源使用 servlet，但对 Web 应用程序的其余部分使用 wicket

Question

I'm trying to add Atmosphere support to a Wicket-1.5.X web application. (Currently upgrading to 6 isn't an option.)

I currently have the wicket filter configured to run on top of the Atmospheres MeteorServlet . I've created an sharedResource for Atmosphere to be used in my application. I'm noticing that however with that configuration even pages(like my static login page) that don't use the shared resource still seem activate it.

I think the solution is to move the wicket filter from On top of the MeteorServlet to next to it. so that /App/MyResource will fire meteor but everything else with just get wicket.

How can I do that?

In Case it Matters:

• Tomcat 6.0.29
• Firefox 16.0.x
• IE 9

UPDATE:
Here is what My web.xml currently looks like:

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

PS: Maybe a fellow wicket Dev knows, does 1.5 still work as a filter or a servlet?

Answer 1

Dunno about this specific case, but typically it's just a matter of adding a definition and mapping to web.xml before the framework (ie Wicket) mapping:

<servlet>
        <servlet-name>myservlet</servlet-name>
        <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
        <servlet-name>myservlet</servlet-name>
        <url-pattern>/mystuff</url-pattern>
</servlet-mapping>
