Question

Hi,
I write down some code and done all process for embeding with oracle forms.
when I run the form then show like this problem.
unable to communicate with runtime process:
code is some code is here:
import java.io.*;
import java.sql.*;
import java.util.Vector;
import oracle.forms.handler.IHandler;
import oracle.forms.properties.ID;
import oracle.forms.ui.VBean;
import java.util.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.tree.*;
import javax.swing.event.*;
import javax.swing.border.*;
public class JTreeBoxPJC extends VBean
static String loginId;
private IHandler mHandler;
private static final ID pSetTitle = ID.registerProperty("TREETEST");
private static final ID pSetText = ID.registerProperty("SETTEXT");
public JTreeBoxPJC()
          super();
          String[] strs = {"JavaGroup","Manjur","Reaz","Shamima","JTree","Kamal","Jamal"}; // 4
          CheckNode[] nodes = new CheckNode[strs.length];
          for (int i=0;i<strs.length;i++) {
          nodes[i] = new CheckNode(strs);
          nodes[0].add(nodes[1]);
          nodes[1].add(nodes[2]);
          nodes[1].add(nodes[3]);
          nodes[0].add(nodes[4]);
          nodes[4].add(nodes[5]);
          nodes[4].add(nodes[6]);
          nodes[3].setSelected(true);
          JTree tree = new JTree( nodes[0] );
          tree.setCellRenderer(new CheckRenderer());
          tree.getSelectionModel().setSelectionMode(
          TreeSelectionModel.SINGLE_TREE_SELECTION
          tree.putClientProperty("JTree.lineStyle", "Angled");
          tree.addMouseListener(new NodeSelectionListener(tree));
try
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
SwingUtilities.updateComponentTreeUI(this);
catch(Exception exception)
exception.printStackTrace();
public void init(IHandler ihandler)
super.init(ihandler);
mHandler = ihandler;
public boolean setProperty(ID id, Object obj)
if(id == pSetTitle)
loginId=(String)obj;
JTreeBoxPJC tt=new JTreeBoxPJC();
return true;
}else if(id==pSetText) {
          loginId=(String)obj;
          JTreeBoxPJC tt=new JTreeBoxPJC();
          return true;
          }else{
               return true;
class NodeSelectionListener extends MouseAdapter {
JTree tree;
NodeSelectionListener(JTree tree) {
this.tree = tree;
public void mouseClicked(MouseEvent e) {
int x = e.getX();
int y = e.getY();
int row = tree.getRowForLocation(x, y);
// TreePath path = tree.getPathForRow(row);
TreePath path = tree.getSelectionPath();
if (path != null) {
CheckNode node = (CheckNode)path.getLastPathComponent();
boolean isSelected = ! (node.isSelected());
node.setSelected(isSelected);
if (node.getSelectionMode() == CheckNode.DIG_IN_SELECTION) {
if ( isSelected ) {
tree.expandPath(path);
} else {
tree.collapsePath(path);
((DefaultTreeModel)tree.getModel()).nodeChanged(node);
// I need revalidate if node is root. but why?
if (row == 0) {
tree.revalidate();
tree.repaint();
//Set_Custom_Property( 'BLOCK3.DIALOG', 1, 'CHECKBOXTREE', DFDF ) ;
pls help me as early as possible.
Manjur
