Tomcat 6到Tomcat 7导致上下文路径停止协作 [英] Tomcat 6 to Tomcat 7 causes context path to stop cooperating

问题描述

我有一个可在Tomcat 6中流畅运行的Web应用程序.假设它在server:8282/MyApplication上运行.我有一个如下所示的上下文xml:

I have a webapp that is working swimmingly in Tomcat 6. Let's say it's running on server:8282/MyApplication. I have a context xml that looks like this:

<Context crossContext="true"
         debug="5"
         docBase="MyApplication"
         path="MyApplication"
         reloadable="true">

在我的应用程序中，我的链接看起来像

In my application, my links look like

server:8282/MyApplication/myAction.do?params=blah

当我将其切换到Tomcat 7时，似乎将链接更改为:

When I switch it to Tomcat 7, it seems to change the link to:

server8282/myAction.do?params=blah

我没有更改应用程序中的任何内容，两个地方的代码都是相同的.我可以更改一些全局设置来重新获得"MyApplication"吗?

I haven't changed -anything- in the application, it's the same code in both places. Is there some global setting I can change to get that "MyApplication" back in?

例如，生成链接的代码为:

the code that generates the link is, as an example,:

<a href="<%=request.getContextPath() %>/myAction.do?params=blah">do the blah</a>

推荐答案

部署过程似乎出了点问题，由于某种原因，Tomcat试图在服务器的根目录上为您的应用程序提供服务，因为您的${pageContext.request.contextPath}返回空.

Seems like something is wrong with your deploying process, and for some reason Tomcat is trying to serve your application at the root of the server, because of that your ${pageContext.request.contextPath} is returning empty.

由于我不确定您的确切部署要求，请尝试以下过程之一.为了确保避免配置冲突，请在全新的Tomcat 7安装上进行操作:

Since I'm not sure of your exactly deployment requirements, try one of the following procedures. Just to be sure and avoid configuration conflicts, do it on a brand new Tomcat 7 installation:

1. 如果您有一个MyApplication.war文件，只需将其放在<CATALINA_HOME>\webapps上，请勿使用任何上下文文件(请注意war文件中的上下文文件，即/META-INF/context.xml)
2. 如果您有爆炸的应用程序，请在webapps内创建一个文件夹MyApplication，然后将应用程序内容放在此处(同样，没有context.xml).

1. If you have a MyApplication.war file just drop it at <CATALINA_HOME>\webapps, do not use any context files (be ware of context files inside the war file, i.e., /META-INF/context.xml)
2. If you have an exploded application, create a folder MyApplication inside webapps and drop the application contents there (again, no context.xml).

如果您确实需要将应用程序保留在webapps之外:

If you really need to keep your application outside of webapps:

1. 在<Host>内的<CATALINA_HOME>\conf\server.xml中添加一个新的Context元素:

1. Add a new Context element to <CATALINA_HOME>\conf\server.xml inside <Host>:

<Context path="/MyApplication"
         docBase="/absolute/physical/path/to/MyApplication" 
         reloadable="true"
         crossContext="true">

或者使用上述内容在<CATALINA_HOME>\Catalina\localhost中创建一个MyApplication.xml文件.

Alternatively create a MyApplication.xml file in <CATALINA_HOME>\Catalina\localhost with the content mentioned above.
