Maven and WebStart (jnlp)

If you plan to deploy your maven application via webstart you are a lucky man, because this is easy if you know how to do it 😉

I tried it without success, but then Geoffrey with his networktools came to my rescue. Now TimeFinder is jnlp-enabled. The following steps were necessary:

1. create a new folder ‘jnlp’ under src/ (where main and test live)
2. put the file template.vm there with:

   <?xml version="1.0" encoding="utf-8"?>
   <jnlp spec="1.0+" codebase="http://timefinder.sourceforge.net/jnlp2" href="$outputFile">
    <information>
       <title>TimeFinder</title>
       <vendor>TimeFinder Team</vendor>
       <homepage href="http://timefinder.sourceforge.net/"/>
       <description kind="one-line">TimeFinder</description>
       <description kind="short">TimeFinder - the automatic timetabling generator for universities and schools</description>
       <description kind="tooltip">TimeFinder - the automatic timetabling generator for universities and schools</description>
       <icon href="http://timefinder.sourceforge.net/jnlp/shamrockwhite.jpg" kind="default"/>
       <shortcut online="false"><desktop/><menu submenu="TimeFiner"/></shortcut>
    </information>
    <security>
    <all-permissions/>
    </security>
    <resources>
       <j2se version="1.6+" initial-heap-size="32m" max-heap-size="128m" />
       <property name="jnlp.versionEnabled" value="true"/>
       $dependencies
    </resources>
    <application-desc main-class="$mainClass">
    </application-desc>
   </jnlp>

3. create a keystore:
   keytool -genkey -alias timefinder -keystore timefinder.jks
   be sure that you use keytool from the same JDK-PATH as you use for maven!
4. add the following to your pom.xml:

   <build>
     <plugins>
       <plugin>
          <groupId>org.codehaus.mojo</groupId>
          <artifactId>webstart-maven-plugin</artifactId>
          <version>1.0-alpha-1</version>
      </plugin>
    </plugins>
    <pluginManagement>
       <plugins>
          <plugin>
             <groupId>org.codehaus.mojo</groupId>
             <artifactId>webstart-maven-plugin</artifactId>
            <!-- do not bind to install phase
             <executions>
              <execution>
                <goals>
                  <goal>report</goal>
                </goals>
              </execution>
             </executions>
             -->
           <configuration>
              <jnlp>
               <mainClass>de.timefinder.core.Startup</mainClass>
              </jnlp>
             <sign>
              <keystore>/home/peterk/Dokumente/quell/timefinder/trunk/timefinder-core/timefinder.jks</keystore>
              <keypass>unsecpwd</keypass>
              <storepass>unsecpwd</storepass>
              <storetype>jks</storetype>
              <alias>timefinder</alias>
              <verify>true</verify>
            </sign>
           <verbose>true</verbose>
         </configuration>
        </plugin>
      </plugins>
     </pluginManagement>
    </build>
   </project>

5. Now you should be able to execute:
   mvn install webstart:jnlp
   which will create a zip file with all the signed jars
6. See my next post for versioning and pack200!
