Bean problem

[danissoares]

Galera, I need to put a mini-browser to view an HTML page inside the Forms. For this, I spoke to the bean area with codes that I have already found ready on the net, but I will need to make some modifications so that it works the way I want and then they started my problems. I took a tutorial on the net that taught how to build a java bean http://forms.pjc.bean-blog.com). iz all as he taught, put the files and everything else in the indicated sites, but nothing works. I followed the step by step tutorial, I rescued things that are a bit different in the 9i, because the tutorial is 10g, but it says it also works for 9i (my version). I will post here the code I did for the jdeveloper (I generated the jar right and I even did another step that is not in the tutorial that is to sign the jar file).
I need to know this urgently, please help me. Abbax follows the source code of the class that I only used to test (it is not the web browser yet).

Select all

package oracle.forms.demo; 
 
import java.awt.Color; 
 
import oracle.forms.handler.IHandler; 
import oracle.forms.ui.CustomEvent; 
import oracle.forms.properties.ID; 
import oracle.forms.ui.VBean; 
 
public class GetCanvasProp extends VBean 
 
{ 
    static IHandler mHandler; 
    // properties you can set 
    protected static final ID SETHIDDEN   = ID.registerProperty("SETHIDDEN");     
    // properties you can be get 
    protected static final ID GETBGCOLOR   = ID.registerProperty("GETBGCOLOR"); 
    // events you can raise 
    protected static final ID EVT_01   = ID.registerProperty("EVT_01");     
     
    // default constructor 
    public GetCanvasProp() 
    { 
      super(); 
    } 
 
    public void init(IHandler handler) 
    { 
      super.init(handler); 
      mHandler = handler; 
      // put your initialisation instructions here 
    }       
  
 /** 
   * Set the properties to the bean 
   **/     
  public boolean setProperty(ID property, Object value) 
  { 
    if(property == SETHIDDEN) 
    { 
       String sParam = (String)value; 
       if(sParam.equals("true")){ 
        setVisible(false); 
       } 
       else { 
          setVisible(true); 
       } 
       return true; 
      }     
    else // default behaviour 
       { 
          return super.setProperty(property, value); 
       }       
  } 
 
 /** 
   * Get the properties of the bean 
   **/ 
  public Object getProperty(ID property) 
  { 
    if (property == GETBGCOLOR) 
    { 
      String sColor = ""; 
      Color color = this.getParent().getBackground(); 
      sColor = "r"+color.getRed()+"g"+color.getGreen()+"b"+color.getBlue(); 
      return color;       
    } 
    else // default behaviour 
    { 
      return super.getProperty(property); 
    } 
  } 
 
 /** 
   * Send a message to the Forms module 
   **/ 
  public void dispatch_event( ID id ) 
  { 
      CustomEvent ce = new CustomEvent(mHandler, id); 
      dispatchCustomEvent(ce); 
  } 
}

Inside the forms I put in the JavaBean Property Implementation Class: oracle.forms.demo.GetCanvasProp

does not give any Error, only the execution of the forms is locked as if the path was incorrect. Can someone help me????

Thanks from now on !!!!
