Matlab <-> Java out of memory [Matlab]

I have built my m-file using Java Builder in Matlab.
I create new project in java IDE:

package matlabtest;
import ecttest.*;
import com.mathworks.toolbox.javabuilder.*;
import java.util.logging.Level;
import java.util.logging.Logger;
/**
*
* @author konrad
*/
public class Main {

/**
* @param args the command line arguments
*/
public static void main(String[] args) {
try {
// TODO code application logic here
Object [] result = null;
Class1 matkl = null;
matkl = new Class1();
result=matkl.ecttest(1, 1);

System.out.println(result[0]);
} catch (MWException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
ex.printStackTrace();
}
}
}

I've built this and everythink was ok.
But when I run my project. There is a message:

Maximum variable size allowed by the program is exceeded.

Error in ==> linspace at 22

Error in ==>
Sensor_element_circular.Sensor_element_circular>Sensor_element_circular.Sensor_element_circular

Error in ==> ecttest at 81

}

Thanks for advice. I have r2009 and I've found solution for my matlabs version:
http://www.mathworks.com/support/solutions/en/data/1-18I2C/
It doesn't work..., but I don't excatly catch why i change sth in matlab when i only use my .jar file. It can be use without even start matlab... I think... maybe i should change sth in MCR (MATLAB Compiler Runtime) (i've read that it interprets sth when we convert .m files to java package)
