将magnoliaPublic上下文内容嵌入到其他Web应用程序上下文中 [英] Embed magnoliaPublic context content into a different web app context

问题描述

我们正在尝试将Magnolia管理的内容嵌入到现有Web应用程序的某些JSP中.在Tomcat中，我们部署并设置了一个 magnoliaPublic 上下文，该上下文沿着我们现有的 app 上下文(即两个不同的WAR文件)运行.在浏览器中，您可以同时访问:

We're trying to embed Magnolia-managed content into some of the JSPs of an existing web app. In Tomcat we deployed and set up a magnoliaPublic context that runs along our existing app context (i.e. two different WAR files). In the browser you can access both:

• http://localhost:8080/app/test.jsp和
• http://localhost:8080/magnoliaPublic/footer

• http://localhost:8080/app/test.jsp and
• http://localhost:8080/magnoliaPublic/footer

因此，例如，我们希望/app/test.jsp包含一个像/magnoliaPublic/footer这样的木兰页面(只是一个div).我们通过添加以下内容来做到这一点:

So, for example, we'd like /app/test.jsp to include a Magnolia page like /magnoliaPublic/footer (just a div). We managed to do it by adding:

<c:import url="http://localhost:8080/magnoliaPublic/footer" />

到/app/test.jsp.几乎可以，但是最好使用相对包含:

to /app/test.jsp. This is almost fine, but a relative include would be best:

<c:import context="/magnoliaPublic" url="/footer" />

后一行抛出

The requested resource (/magnoliaPublic/footer) is not available

我怀疑这是由于Magnolia的过滤器链的工作方式造成的，尽管它已设置为分派INCLUDE，并且所有服务器/过滤器/调度/*条目的toMagnoliaResources都设置为true.

I suspect this is due to the way Magnolia's filter chain works, though it's set to dispatch INCLUDE and all server/filters/dispatching/* entries have toMagnoliaResources set to true.

任何提示将不胜感激.

谢谢.

推荐答案

Tomcat默认情况下不允许您访问其他Servlet上下文.我想这就是您使用context属性的c:import失败的原因.

Tomcat does not allow you to access another Servlet Context by default. I guess that is the reason why your c:import using the context attribute fails.

Tomcat具有crossContext属性，该属性对此进行配置:

Tomcat has the crossContext attribute which configures this:

如果要在此应用程序内调用ServletContext.getContext()以成功返回在此虚拟主机上运行的其他Web应用程序的请求分派器，请设置为true.在注重安全的环境中设置为false(默认值)，以使getContext()始终返回null.

Set to true if you want calls within this application to ServletContext.getContext() to successfully return a request dispatcher for other web applications running on this virtual host. Set to false (the default) in security conscious environments, to make getContext() always return null.

启用crossContext可能会解决您的问题.

Enabling crossContext might solves your problem.
