Sorry, I forgot to add this inside accept(): System.out.println(getMap().size());

Hi, I'm having a trouble with this:

It seems that somehow I'm not accessing correctly the myMap member of the class:

public class MyClass implements javax.xml.stream.StreamFilter()  {  private Map myMap= new HashMap();  public Map getMap()  {  return this.myMap;  }  public void addElement(String text)  {  this.myMap.add(text);  }  public static void main()  {  XMLInputFactory xmlif = null;  xmlif = XMLInputFactory.newInstance();  FileInputStream fis = new FileInputStream("myFile.xml");  XMLStreamReader xmlr = xmlif.createFilteredReader(xmlif.createXMLStreamRe ader(fis),new MyClass());  addElement("Something")  }  public void accept()  {  if ( getMap().containsKey("Something") )  {  System.out.println("The value is there");  }  }  }  When I try to do this, it says that the size is 0.
