    Cannot run

    Gui Sim Newbie

      Hello everyone !

      I'm interested in Infinispan so I thought I'd give it a try.

      The home page mentions the runGuiDemo and it felt like a great way to be introduced to Infinispan.

      Sadly, the demo doesn't seem to work. I downloaded infinispan-4.0.0.ALPHA4-all and infinispan-4.0.0.ALPHA4-bin from Sourceforge, unzipped, tried to run runGuiDemo.bat ...

      I get this error :

      Exception in thread "main" java.lang.NoClassDefFoundError: and
      Caused by: java.lang.ClassNotFoundException: and
       at java.net.URLClassLoader$1.run(Unknown Source)
       at java.security.AccessController.doPrivileged(Native Method)
       at java.net.URLClassLoader.findClass(Unknown Source)
       at java.lang.ClassLoader.loadClass(Unknown Source)
       at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
       at java.lang.ClassLoader.loadClass(Unknown Source)
       at java.lang.ClassLoader.loadClassInternal(Unknown Source)
      Could not find the main class: and. Program will exit.


      Can anyone help ?

      Also, I'd like to know if there are any plans for a User mailing list ?

      Finally, I am wondering if Infinispan has a local copy of the Cache when used with REPL_SYNC.
      What I actually want to know is wether "read" actions are local.

      Thanks !

          For some reason, this thread's title was supposed to be "Cannot run runGuiDemo.bat and other questions "

          I can't edit my original post.. and I can't modify the thread's title.

          Simply " Cannot run " sounds kind of rude. Wish I could change it ;)

            LOL! I won't take it personally.

            Yes, that's why we have one. Nice, friendly way to get into it.

            That's very odd. We primarily develop on Unix environments so I must say the windows script has received much less testing than the Unix one. Could you edit the script and echo out the Java command being run, before running it?


            Also, I'd like to know if there are any plans for a User mailing list ?


            From my experience, users work best with forums like this, purely because of better searchability, etc. I do know though that there are some plans to merge the forums and mail lists into a single entity which you can interface with either by email or on the web.

            Yes. :-)

              Thanks for the reply !

              I finally got it to work.. and now I feel kind of stupid.

              The problem was that I extracted the demo in C:\Documents and Settings\USER\My Documents\

              The script added those in the classpath.. but you can't have spaces there !

              It couldn't find the class " and " because of " Document and Settings " !!...

              Now the whole thing works.

              I think that the script should use quotes around directory names, that should fix this.
              If not, at least put a note somewhere mentioning this ;)

              Also, about the forums vs mailing list, if you plan to stick with the forums, you might want to consider putting a link on the front page. Right now you have to dig around quite a bit to find it ;)

              Thanks !

              But now.. I have another question.

              I have a cluster running. From time to time, I insert something in the map. Now when a new "client" joins the cluster and displays his synchronized map, all items added prior to him joining are not present ! Only items that were added after the new client joined are in his map.

              Is this supposed to be like that ? Using REPL_SYNC, I expected his map to be synchronized automatically when he joins the server.

                Glad you got it working. If you feel like contributing a patched .BAT file, we'd appreciate that ...

                Good point. Done, it is now on the front page of www.infinispan.org

                Enable state transfer (fetching of state on startup) either via XML or your Configuration bean.

                  Again, due to a lack of EDIT .. I have to double post..

                  I just read from another thread that in order to have late joiner sync with the cluster, I need to use :

                  <state Retrieval timeout="20000" fetchInMemoryState="true"/>

                  Is there a way to do this programmaticaly ?

                  is

                  Configuration.setFetchInMemoryState(true)
                  enough?

                    That should be enough. The default state transfer timeout is 10000 ms, so use setStateRetrievalTimeout() method to change that if necessary.
