F.A.Q.

  • Which version of Weka is based on Weka4WS? It based on the version 3.4.12 (released the 12th of December 2007)
  • What are Weka4WS requirements? Weka4WS requires the Globus Toolkit 4.0.x (full installation) on the computing nodes and only the Java WS Core (a subset of Globus Toolkit) on the user nodes; the user must hold a valid grid certificate in the X.509 format and must be mapped (through the grid-mapfile) on a local user on every computing node where the Weka4WS service is running. See the Installation page for further details;
  • Does Weka4WS client run on Windows machines?Yes, since version 2.0 (released the 10th of April 2008), Weka4WS may run also on Windows machines;
  • Is Weka4WS open source? Yes, it is: the sources files are included with the client and service packages. You can redistribute it and/or modify it under the terms of the GNU General Public License. See the Download page for further details;
  • Does Weka4WS work with Globus Toolkit 4.2.x? Weka4WS has been tested only with Globus Toolkit 4.0.x. Globus Toolkit 4.2.x contains an upgrade to the web services specifications used by the toolkit (to the final WSRF and WS-Notification specifications) as well as new features in all services.  Due to the specification upgrade, the web services are incompatible with the 4.0.x series. We haven’t planned to make Weka4WS be compatible with GT 4.2.x in the near future.

      Hi…
      Have u got any material to use weka4ws in our own Java program.
      If so please let me know the example.
      Thank U….

      • If with “material” you mean documentation then no sorry, there are no tutorials available at the moment. You can figure out how to use it by having a look at the source code of the following classes:

        weka4ws.gui.explorer.ClassifierPanel
        weka4ws.gui.explorer.ClustererPanel
        weka4ws.gui.explorer.AssociationsPanel
        weka4ws.gui.kflow.Classifier
        weka4ws.gui.kflow.Clusterer

  2. Yes, you can use Weka4WS libraries in your Java code. Everything you need is inside the weka4ws.core package. There are no tutorials available at the moment; you can figure out how to use it by having a look at the source code of the following classes:

    weka4ws.gui.explorer.ClassifierPanel
    weka4ws.gui.explorer.ClustererPanel
    weka4ws.gui.explorer.AssociationsPanel
    weka4ws.gui.kflow.Classifier
    weka4ws.gui.kflow.Clusterer

    Where can I find a WSDL of services provided by Weka4WS? Suppose that I don’t want to use your client, but I need to run your services from my terminal by calling your services described in WSDL.

    • You can find the Weka4WS WSDLs in the schema/weka4ws/ directory of the service package you can freely download from:

      http://grid.deis.unical.it/weka4ws/index.html?page=main.html&section=download

      • bramantoro says:

        Thanks for your quick response. I meant how can I get WSDL of all Weka services without installing Weka4WS. In schema/weka4ws/ directory, there are only two WSDLs to access Weka4WS services, not Weka services.

        And when I ran Weka4WS.wsdl or Weka4WSFactory.wsdl, I got an error that seems to be I have to install the services by myself. Do you provide any web service servers that can receive my request through these two WSDLs without installing the service in my terminal?

    • I am sorry but I am not sure I understood your question. The WSDL of the Weka4WS service are indeed in the schema/weka4ws/ directory. WSDL files don’t contain executable code, they are used for describing the functionality offered by the Weka4WS service.

      As for your last question, no, unfortunately we don’t provide the Weka4WS web services on a public server.

    I tried to install Globus Toolkit 4.0.8 in latest fedora and ubuntu, but it failed. :(
    What if I try 5.0.4 or 4.2.1? Any lucky chance with Weka4WS?
