Re: [jetty-users] Communication between a Servlet and a custom protocol

[Josh Spiegel <joshlakewg@xxxxxxxxx>]

Simone, 

Thanks again.  Bug it seems the webapp configuration can't reference ids set by the server module.  Am I missing something?  Here is what I tried:

./webapps/servlet.xml

<Configure class="org.eclipse.jetty.webapp.WebAppContext">

  <Set name="contextPath">/ServletExample</Set>

  <Set name="war">/Users/..../ServletExample.war</Set>

  <Get class="java.lang.System" name="out">

   <Call name="println">

    <Arg>######### SERVLET ##############</Arg>

   </Call>

  </Get>

  <Get class="java.lang.System" name="out">

   <Call name="println">

    <Arg><Ref refid="myContext"/></Arg>

   </Call>

  </Get>

</Configure>

./modules/test.mod

[xml]

etc/test.xml

./etc/test.xml

<Configure id="Server" class="org.eclipse.jetty.server.Server">

  <Map id="myContext">

    <Entry>

      <Item>test</Item>

      <Item>foo</Item>

    </Entry>

  </Map>

  <Get class="java.lang.System" name="out">

   <Call name="println">

    <Arg>######### test.xml ##############</Arg>

   </Call>

  </Get>

  <Get class="java.lang.System" name="out">

   <Call name="println">

    <Arg><Ref refid="myContext"/></Arg>

   </Call>

  </Get>

</Configure>

> java -jar start.jar --add-module=test

null

Notice the servlet.xml reference to "myContext" prints null.

Thanks,

Josh

<Map id="myContext"> will allow you to obtain the map by using <Ref
refid="myContext"/> so you don't need the Server anymore.
