I am using Rhino to access methods and objects of java classes. I am trying to access a method of class as follows:
 
function test1(p1, p2, p3){
         e = new xyzException();
        try{
                  printStr("Calling API ");
                  abcUtil.abcImport(p1, p2, p3);
        } catch (e) {
                  printStr("RESULT=FAILURE");
                  printStr(e.toString());
                  printStr(e.getMessage()); <--- this line throws error shown below
        }
          
}

However, I get an error 
js: "C:\rhino\impExp.js", line 116:
 uncaught JavaScript exception: TypeError: undefined is not a function. (C:\rhino\impExp.js; line 116)

 
I am accessing an exception that extends java.lang.Exception.
Here is how the exception class looks like:

java.lang.Object  java.lang.Throwable      java.lang.Exception          com.remedy.arsys.api.xyzException

In the implemention of xyzException, the methods are defined as:
 
public  class xyzException extends java.lang.Exception  {
 
public String getMessage() {
  return this.toString();
 }
 
public String toString() {
     String msg = "";
 
  if (null == getLastStatus())
   msg = null;
  else {
   for (int i = 0; i < getLastStatus().length; i++)
       msg += getLastStatus()[i].toString();
  }
 
  return msg;
 }

}
