Tango on Jetty

Web Services Interoperability Technology (WSIT, aka Project Tango), integrated in GlassFish V2 builds, provides a implementation of key enterprise Web services specifications and enables first-class interoperability with .NET 3.0 framework. However if you download stand-alone WSIT builds, then you can also install similar bits on Tomcat 5.5.17. In this entry, I provide a script that allows you to install the same bits on Jetty 6.1.0.

1. Download WSIT Milestone 4 and J2SE 5.0 U2 or later.
2. Install (detailed instructions) the bundle by giving the following command:
   
   java -jar wsit-1_0-fcs-bin-b14-09_apr_2007.jar
3. Copy the script below in 'jax-ws-latest-wsit' directory and name it as 'wsit-on-jetty.xml':
   
   <?xml version="1.0"?>

<project name="WSIT 1.0 Beta On Jetty" default="help" basedir=".">
  <property environment="env"/>
  <property name="jetty.home" value="${env.JETTY_HOME}"/>
  <property name="jetty.lib.home" value="${jetty.home}/lib"/>
  <property name="java.home" value="${env.JAVA_HOME}"/>
  <patternset id="wsit-jars">
    <include name="webservices-rt.jar"/>
    <include name="webservices-tools.jar"/>
    <include name="webservices-extra.jar"/>
    <include name="webservices-extra-api.jar"/>
    <include name="webservices-api.jar"/>
  </patternset>

  <target name="install" description="Install latest WSIT jars on Jetty 6.1.x">
    <echo message="Installing WSIT 1.0 Beta on ${jetty.home} ..."/>

    <copy toDir="${jetty.lib.home}" overwrite="true">
      <fileset dir="lib">
        <patternset refid="wsit-jars"/>
      </fileset>
    </copy>
    <echo message="... installation complete."/>
  </target>

  <target name="uninstall" description="Install latest WSIT jars on Jetty 6.1.x">
    <delete>
      <fileset dir="${jetty.lib.home}">
        <patternset refid="wsit-jars"/>
      </fileset>
    </delete>
  </target>

  <target name="help">
    <echo message="install :"/>
    <echo message=" Installs WSIT 1.0 Beta on Jetty 6.1.x"/>
    <echo/>
    <echo message="uninstall: "/>
    <echo message=" Uninstalls WSIT 1.0 Beta from Jetty 6.1.x"/>
    <echo/>
    <echo message="$JETTY_HOME must be set to the installation directory of Jetty 6.1.x."/>
    <echo/>
    <echo message="Usage:"/>
    <echo message=" ant -f wsit-on-jetty.xml {install,uninstall}"/>
  </target>
</project>
4. Download and install (basically unzip the downloaded file) Jetty 6.1.0. Set an environment variable JETTY_HOME pointing to the location of Jetty install directory.
5. Invoke the command to install WSIT M4 bits on Jetty as:
   
   ant -f wsit-on-jetty.xml install
6. Create a Reliable WSIT endpoint by choosing 'J2EE 1.4' as the 'Java EE version' and make sure 'Set Source Level to 1.4' is unchecked.
7. Copy the WAR file from the 'dist' directory of your application such '\Users\Arun Gupta\WebApplication1\dist\WebApplication1.war' to 'JETTY_HOME/webapps'.
8. Start Jetty instance using the following command:
   
   java -jar start.jar etc/jetty.xml
   
   It's weird that 'bin' directory contains only 'jetty.sh' (no .bat script) and the only way documented to run is using this command.
9. The endpoint should now be available at: 'http://localhost:8080/<context-root>/<service-name>?WSDL', for example 'http://localhost:8080/WebApplication1/HelloService?WSDL'. Note, Jetty does not seem to support hot deployment. So if you drop a WAR file in 'webapps' directory then you need to re-start your Jetty instance.
   
   
10. A Web service client to this endpoint can be easily generated following #ws2 screencast.
    
    

This is one trivial sample. If you try other interesting combinations and they don't work, please file an issue.
