Maven, Jetty, JOTM

Question

Hi all,

I have been unable to configure JOTM ontop of Jetty inside a Maven build environment. The exception I get when I try to run my application is the following:

2009-07-21 19:47:23.499::WARN:  Config error at <New id="UserTransaction" class="org.mortbay.jetty.plus.naming.Transaction"><Arg>
          <Ref id="ut"/>
         </Arg></New>
    [INFO] Jetty server exiting.
    [INFO] ------------------------------------------------------------------------
    [ERROR] BUILD ERROR
    [INFO] ------------------------------------------------------------------------
    [INFO] Failure

    A flat name can only have a single component

I am using this as a reference:http://docs.codehaus.org/display/JETTY/JOTM

jetty.xml (jettyConfig in maven's pom.xml, this is actually being seen)

carol.properties (not so sure this is being seen, but from the exception, is this even relevant?)

carol.start.ns=false
carol.start.jndi=false
carol.protocols=jrmp
carol.start.rmi=false
carol.jvm.rmi.local.call=true
carol.jndi.java.naming.factory.url.pkgs=org.mortbay.naming

Any ideas?

Thanks, Walter

Where is carol.properties located in your project?

Maven resources need to be under src/main/resources. Jetty expects carol.properties to be in the resources folder.

So you may need to move carol.properties to src/main/resources/resources so the file is copied to target/resources by the process-resources stage before Jetty is launched.
