GWT Notes

An Ant rule for restarting Tomcat when building a GWT app:

  <target name="deploy" depends="war" description="Copy WAR file to Tomcat">
    <property name="apache.home"
              location="/home/dominicc/apache-tomcat-6.0.18" />
    <exec executable="${apache.home}/bin/shutdown.sh" />
    <delete dir="${apache.home}/webapps/TestApp" failonerror="false" />
    <copy todir="${apache.home}/webapps" file="TestApp.war" />
    <exec executable="${apache.home}/bin/startup.sh" />
  </target>

The argument to the 'gwtc' target to dump the internal AST:

  <jvmarg value="-Dgwt.jjs.dumpAst=/tmp/ast"/>
