Passing Array to a method

Question

Hi,
There is a class MyClass that implements Serializable. I need to create array of this class and pass to a method.
In java, this can be done as following:
               MyClass[] myClassVariables=new MyClass[2];
               MyClass myClassInstance1=new MyClass();
               MyClass myClassInstance2=new MyClass();
               myClassVariables[0]=myClassInstance1;
               myClassVariables[1]=myClassInstance2;
               String message = getValues(myClassVariables);
import java.io.Serializable;
public class MyClass implements Serializable{
public String getValues(MyClass[] myClassVariables)
When I implement this in a workflow, I get the following error:
XPRESS exception:
com.waveset.util.WavesetException: Couldn't find method getValues(java.lang.String, java.lang.String) in class MyClass
java.lang.NoSuchMethodException: MyClass.getValues(java.lang.String, java.util.ArrayList)
Code I am using is as following:
<set name='myClassInstance1'>
<new class='com.marathon.MyClass'/>
</set>
<set name='myClassInstance2'>
<new class='com.marathon.MyClass'/>
</set>
<set name='myList'>
<new class='java.util.ArrayList'/>
</set>
<set name='myClassVariables'>
<list>
<ref>myClassInstance1</ref>
<ref>myClassInstance2</ref>
</list>
</set>
<set name='message'>
<invoke name='getValues' class='MyClass'>
<ref>myClassVariables</ref>
</invoke>
</set>
<ref>message</ref>
Please help me,
Thanks

You might want start by reading a few books on OO design first.
What you will probably want to do is have a class which stores the array and extends ActionListener...
public class Gui extends ActionListener {
  Person[] ppl = new Person[100];
  Component comp;
  Button addPersonButton;
  public Gui () {
    comp = new .....;
    addPersonButton = new Button("Add person");
    comp.add(addPersonButton);
    comp.addActionListener(this);
  public static void main(String args[]) {
    Gui gui = new Gui();
  public void actionPerformed(ActionEvent e) {
    if (e.getSource() == addPersonButton) {
      doAddPerson();
  pulbic void doAddPerson() {
    ppl[0] = ....
}Hope this shows you a bit more. Not sure how good my design of gui's is though :-/
