Tomcat似乎无视新 <Context> server.xml中的元素

Question

after reading various questions about how to handle images on tomcat I followed the approach to set a folder with images at tomcat following the instructions here: Simplest way to serve static data from outside the application server in a Java web application but it doesn't work and I cannot understand what I am doing wrong.

I've set the context in server.xml as described:

 <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">



    <Context docBase="C:\ServerFiles\" path="/images" />


        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />

      </Host>

and I also tried this:

    <Context docBase="C:\ServerFiles" path="/images" />

instead of the above.

The image is located at

C:\\ServerFiles and its name is index.jpg

and this is how i try to retrieve it with jsf

<img src="/images/index.jpg" />

but it doens't work

Can you help me? I cannot understand what I am doing wrong.

If editing Tomcat's server.xml (or context.xml or web.xml or what not which resides in its /conf folder) appears to have no effect, then it's a strong hint that you're using an IDE which has taken over the control from Tomcat. Eclipse for example does that by default. When you add Tomcat server in Eclipse, then it basically creates a copy of its /conf folder into the IDE's Servers project, uses the IDE workspace as deploy space and solely uses Tomcat server's engine to run projects against the config in Servers project and deployments inside workspace.

You have basically 2 options:

1. Edit the configuration files in Servers project instead.

2. Tell Eclipse to not take over control from Tomcat but instead use (and manipulate!) it directly. Doubleclick the Tomcat entry in Servers view, select in the section Server location the option Use Tomcat installation .

The way you've defined Context should work. I cross checked a project where I do this and I didn't see any issue on your server.xml .

Maybe you have a separate context.xml in the METAINF folder of your web module that overrides the setting here.

BTW the second example without the trailing \\ is the correct way to do it.
