Fail to run rapidminer in java runable jar

Hi everyone, 

I use rapidminer as a library in my java project. Everything works fine if I run my project in Eclipse. But recently I export my project into a runable jar file and I am not able to run it.


I initialize the rapidminer in my main GUI: RM rm = new RM() where the constructor of RM is :

public RM(){

try {
ClassLoader classLoader = getClass().getClassLoader();

mainProcess = new Process(classLoader.getResourceAsStream(".\\RMprocess\\association-rule.rmp"));

inputOprt = mainProcess.getOperator("Read CSV");
n2bOprt = mainProcess.getOperator("Nominal to Binominal");
fpgOprt = mainProcess.getOperator("FP-Growth");
asOprt = mainProcess.getOperator("Create Association Rules");
} catch (IOException e1) {
} catch (XMLException e1) {

After the initialization, if I press any of the button in my GUI, I find the rm null.

public void actionPerformed(ActionEvent arg0) {

Object component = arg0.getSource();

if(component == button11){
if(rm == null){
System.out.println("rm null");
JFileChooser fileChooser = new JFileChooser();
if(fileChooser.showOpenDialog(this) == JFileChooser.APPROVE_OPTION){
file = fileChooser.getSelectedFile();

In this case, I receive "rm null" on the console.

I am urgent to fix this problem.

    I am late to reply, but just wondering if you were able to resolve this issue.

    if not, do you see any exceptions been caught in your RM contructor
