This object is able to be serialized for storage on disk.<p> This class is experimental at present. Has been tested using CSVResultListener (sending results to standard out) and DatabaseResultListener (InstantDB + RmiJdbc bridge). <p> Getting started:<p> Start InstantDB (with the RMI bridge) on some machine. If using java2 then specify -Djava.security.policy=db.policy to the virtual machine. Where db.policy is as follows: <br> <pre> grant { permission java.security.AllPermission; }; </pre><p> Start RemoteEngine servers on x machines as per the instructons in the README_Experiment_Gui file. There must be a DatabaseUtils.props in either the HOME or current directory of each machine, listing all necessary jdbc drivers.<p> The machine where a RemoteExperiment is started must also have a copy of DatabaseUtils.props listing the URL to the machine where the database server is running (RmiJdbc + InstantDB). <p> Here is an example of starting a RemoteExperiment: <p> <pre> java -Djava.rmi.server.codebase=file:/path to weka classes/ \ weka.experiment.RemoteExperiment -L 1 -U 10 \ -T /home/ml/datasets/UCI/iris.arff \ -D "weka.experiment.DatabaseResultListener" \ -P "weka.experiment.RandomSplitResultProducer" \ -h rosebud.cs.waikato.ac.nz -h blackbird.cs.waikato.ac.nz -r -- \ -W weka.experiment.ClassifierSplitEvaluator -- \ -W weka.classifiers.bayes.NaiveBayes </pre> <p> The "codebase" property tells rmi where to serve up weka classes from. This can either be a file url (as long as a shared file system is being used that is accessable by the remoteEngine servers), or http url (which of course supposes that a web server is running and you have put your weka classes somewhere that is web accessable). If using a file url the trailing "/" is *most* important unless the weka classes are in a jar file. <p><P><P><DL><DT><B>Version:</B></DT> <DD>$Revision: 1.13.2.2 $</DD><DT><B>Author:</B></DT> <DD>Mark
