    "Can't find marker file for webRoot" while using mvn tomcat:run

    Hello,
    I'm developing a maven based springframework-jpa application. When I run

    Code:
    mvn tomcat:run
    the application loads showing a "Can't find marker file for webRoot" error in the log, when I load the host-page a NPE is thrown.


    Code:
    === 2012-12-18 15:19:41,303 [main] INFO  ISCInit - Isomorphic SmartClient/SmartGWT Framework (v8.3_2012-11-20/EVAL Deployment 2012-11-20) - Initialization Complete

    The error message means what it says - that file should be present, and if it isn't, your Maven script isn't doing the equivalent of the installation instructions.

    As a hint, invoking the GWT compiler is what causes those files to be copied in the deployment directory, from inside smartgwtee.jar.

      I execute

      Code:
      > mvn package
      first; this creates the file
      Code:
      > find -name  builtinTypes.xml
./target/cargill-ordermanagement-0.1.0.BUILD-SNAPSHOT/applicationScaffold/sc/system/schema/builtinTypes.xml
      but I still get the error message

      what's wrong with this?

      Thank you.

      PS Dont' mind the double log binding :-)

      PPS the app deployed in tomcat works ...
      PPPS the app run by
      Code:
      mvn gwt:run
      works ...

        Looking at your logs, the real webroot is probably:

        file:/home/lrkwz/cargill/cargill-parent/cargill-ordermanagement/target/cargill-ordermanagement-0.1.0.BUILD-SNAPSHOT
        .. but the webroot Tomcat is telling us doesn't match:

        === 2012-12-20 09:57:42,709 [main] ERROR ISCInit - Can't find marker file for webRoot: /home/lrkwz/cargill/cargill-parent/cargill-ordermanagement/src/main/webapp/applicationScaffold/sc for configured/autodetected webRoot
        At a glance, it looks like something about 'mvn tomcat:run' makes Tomcat mis-report the webroot as the directory where you keep your source code.

        FYI we detect webroot via the standard approach (servletContext.getRealPath("/")). Webroot can also be manually set in server.properties (see docs in that file).
