Question

Is there an easy way to map a directory in the web.xml or other deployment descriptor (jetty.xml, etc) files?

For example, if I have a directory /opt/files/ is there a way that I can access its files and sub-directories by visiting http://localhost/some-mapping/? It strikes me that there should be some simple way of doing this, but I haven’t been able to find out how (via google, stackoverflow, etc). All I’ve found are servlets that mimic fileservers, which is not what I would like.

For reference I am using jetty on an AIX box.

No idea how to do it with Jetty, but in Tomcat you can just add a new <Context> to server.xml:

<Context docBase="/opt/files" path="/files" />

This way it’s accessible by http://example.com/files/.... See if something similar exist for Jetty.

Update: after Googling, the “normal Java code” equivalent would be something like:

WebAppContext files = new WebAppContext("/opt/files", "/files");
Server server  = new Server(8080);
server.setHandler(files);
server.start(); 

Now yet to translate that into jetty.xml flavor. I am a bit guessing based on the documentation and examples found on the web, so don’t pin me on it:

<Configure class="org.mortbay.jetty.webapp.WebAppContext">
    <Set name="webApp">/opt/files</Set>
    <Set name="contextPath">/files</Set>
</Configure>

Another possibility may be this:

<Configure class="org.mortbay.jetty.Server">
    <Call name="addHandler">
        <Arg>
            <New class="org.mortbay.jetty.webapp.WebAppContext">
                <Arg name="webApp">/opt/files</Arg>
                <Arg name="contextPath">/files</Arg>
            </New>
        </Arg>
    </Call>
</Configure>
