    Re: whack weather example usage

    Hi, for testing you can use Psi for example, add your weather component in your buddy list and send him a message with a weather station from http://weather.noaa.gov/ (see the attached screenshot).But for a comfortable usage, yeah, maybe you can write a client

    Re: whack weather example usage

    I read that the weather example was in a sample folder in the source. I downloaded the source zip and did not find it.

     

    Q: Where are you getting the weather example these days?

     

    Thanks,

      Re: whack weather example usage

      You can get it via subversion

       

      svn co http://svn.igniterealtime.org/svn/repos/whack/trunk whack

       

      But currently I think you can't compile the trunk if you don't fix some old references. See my attached patch to compile and run the actual revision (11087).

       

      Best regards

        Re: whack weather example usage

        I changed the whack.jar build compile target includes in order to pick up the xmpp classes. That allowed me to use whack.jar in my component project. I hope I'm on the right track..

        Thanks!

         

         

        <target name="jar" depends="compile" unless="jar.uptodate" description="Produces whack.jar">
                <jar destfile="${jar.dest.dir}/whack.jar"
                     basedir="${compile.dir}"
                     includes="org/**/*.class" />
                  <!-- includes="org/jivesoftware/whack/**/*.class" -->

          Re: whack weather example usage

          1) I rebuild whack.jar from SVN - just needed to modify the build.xml to include more classes in whack.jar.

           

          2) I got the weather sample to compile against these jars:

           

              commons-httpclient.jar

              dom4j.jar      

              jweather.jar

              tinder-1.0.0.jar

              xpp3.jar
              commons-logging.jar   

              jakarta-oro.jar

              log4j.jar   

              whack.jar

           

          2) When I try to run the weather example I get:

           

          Exception in thread "main" java.lang.NoClassDefFoundError: org/jivesoftware/stringprep/IDNA

                  ... 5 more

           

          3) It looks like the missing class is required by the tinder jar. My goal is to run the weather example.

            Woops, sorry - found stringprep.jar to fix my runtime problem

             

            Weather example is running, thanks!

            I fixed the current trunk version of whack for the updated API and libraries.

              Got to bump this discussion up.

               

              I just downloaded the whack trunk from svn (rev 12148), it seems I cannot build it using ant.

                whack weather example usage

                Oh well, I just downloaded the whole jetty distribution and put each jar inside the lib/merge folder... not sure wether this was a good idea, but it worked.

                 

                The Whack 1.0.jar which can be found on this website doesn't work anymore (missing Log class, at least) - maybe someone should update it?

                 

                For this weather example, the jweather.jar was missing, too.

                  whack weather example usage

                  I have another solution for compiling the Whack library.Just download "jetty-all-server-7.0.2.RC0.jar" and add build/ merge and run the ant file. This worked for me and had written a sample external component and thats working fine.
