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"

and here is the error when I run the programm:
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);
}
I think RM can not load my plugin which contains my operator. So I used the following code:

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?0
