Problem with Calling RM from my own standalone program

Hi all,

I have a bad problem with running an RM process from my own program. Before this time I could run RM processes in my program without any problem. But now, I want to run a process process which contains one of my own operators (my own cluster validator). It should be noted that my new operator works fine separately when I use it in RM as a plugin. But I cannot run the process containing it in my own program. here is the code"

RapidMiner.setExecutionMode(com.rapidminer.RapidMiner.ExecutionMode.EMBEDDED_WITH_UI);
File xmlFile = new File(getClass().getResource("/com/rapidminer/resources/process.xml").toString());
Process pr;
try {
pr = new Process(new File("process.xml"));

} catch (IOException e) {

throw new WrappedException(e);

} catch (XMLException e) {

throw new WrappedException(e);
}
 try {
pr.run();
} catch (OperatorException e) {

throw new WrappedException(e);
}
and here is the error when I run the programm:

I think RM can not load my plugin which contains my operator. So I used the following code:
System.setProperty(RapidMiner.PROPERTY_RAPIDMINER_INIT_PLUGINS_LOCATION, "E:\\M\\Eclipse_After20-11-90\\eclipse\\WS\\RapidMiner_Unuk\\lib");
But Again the same error appears. Any help would be appreciated.

    Hi,

    I found the Problem....

    I should always remember not to reference to other projects in eclipse, instead, I should add their library.

    I also changed the execution mode like this:
    RapidMiner.setExecutionMode(com.rapidminer.RapidMiner.ExecutionMode.EMBEDDED_WITHOUT_UI);
    Does anyone know when should we use WITH_UI and when WithoutUI?
