如何为特定资源拥有servlet，但如何在web应用程序的其余部分使用wicket

Question

我试图在Wicket-1.5.X web应用程序中添加气氛支持。(目前升级到6不是一种选择。)

目前，我已经将wicket过滤器配置为运行在气氛MeteorServlet之上。我已经为我的应用程序中使用的气氛创建了一个sharedResource。但是，我注意到，对于这种配置，即使是不使用共享资源的页面(比如我的静态登录页面)也似乎仍然激活它。

我认为解决方案是将wicket过滤器从MeteorServlet的顶部移到它的旁边。因此，/App/MyResource将触发流星，但其他一切只需使用get wicket即可。

我怎么能这么做？

在重要的情况下：

• Tomcat 6.0.29
• Firefox 16.0.x
• IE9

下面是我的web.xml当前的样子：

P.S.：也许wicket知道，1.5仍然是一个过滤器还是一个servlet？

不知道这个具体情况，但通常只是在框架(即Wicket)映射之前向web.xml添加定义和映射：

<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>
