Why this tree can not show on the Applet?

hi, all, I try to create a java Applet show a tree, this following code has no error, but the tree can not show on the Applet, can any one tell me why? thanks!
<code>
import java.awt.*;
import java.applet.Applet;
import java.awt.event.*;
import java.util.*;
import javax.swing.*;
import javax.swing.tree.*;
import java.awt.dnd.*;
public class AppletApp extends Applet {
     Date myDate;
     protected JTree m_tree = null;
     protected DefaultTreeModel m_model = null;
     protected JTextField m_display;
     public void init() {
     public void paint(Graphics g) {
          DefaultMutableTreeNode root = new DefaultMutableTreeNode("root");
          DefaultMutableTreeNode node1 = new DefaultMutableTreeNode("node1");
          root.add(node1);
          node1.add(new DefaultMutableTreeNode("sub1_1"));
          node1.add(new DefaultMutableTreeNode("sub1_2"));
     public static void main(String arg[]) {
          JFrame myFrame = new JFrame();
          Container contentPane = myFrame.getContentPane();
          contentPane.setLayout(new GridLayout(1,2));
          AppletApp app = new AppletApp();
          contentPane.add(new JScrollPane(app), BorderLayout.CENTER);
          myFrame.addWindowListener (new WindowAdapter() {
               public void windowClosing(WindowEvent e) {
                    System.exit(0);
          app.init();
          app.start();
          myFrame.setSize (400,400);
          myFrame.setVisible(true);
</code>

Not quite sure what you are trying to do, but if you move the code from the paint() method into the init() method (then delete your paint() method), then add one new line to the init() method (after the code you just inserted) that reads:
getContentPane().add(new JTree(root));
- You should at least see a tree!

Can we display ICONS in ALV list?

Hi,
   Is it possible to display icons (ICON_GREEN_LIGHT) in the ALV list using the function module REUSE_ALV_LIST_DISPLAY.
   Is there any possibility of displaying a list using object oriented ALV?
Thanks and Regards,
Lakshmi.

Why the validator can't display the error message on the popup dialog?

I have input text with a validator and a custom ok button and a cancel button on the popup dialog.When I click the ok button,the validator will validator the input value on the input text,but it just close the popup dialog without display the message firstly.The point is it does validate the value but doesn't display the message.Can anybody help?

It seems if I use the button which is associated with the dialog the validator works well,but if I use the custom button the error message doesn't display. the environment is 11g.
the code of the page is :
<af:form>
<af:popup id="copyPopupDialog" contentDelivery="lazyUncached">
<af:dialog title="validator" closeIconVisible="false" type="none">
<af:inputText id="copyReportsetCode" styleClass="" label="code"
value="11"
validator="#{reportSetManagedBean.validatCode}"></af:inputText>
<f:facet name="buttonBar">
<af:panelGroupLayout layout="horizontal" halign="right">
<af:commandButton text="ok"/>
<af:commandButton text="cancel" immediate="true"/>
</af:panelGroupLayout>
</f:facet>
</af:dialog>
</af:popup>
<af:commandButton text="commandButton 1">
<af:showPopupBehavior popupId="copyPopupDialog"/>
</af:commandButton>
</af:form>
the code of the managedbean is:
package david;
import javax.faces.component.UIComponent;

How can I display icons on the bookmark bar?

Does anyone know how to display a webpage's icon on the bookmark bar instead of the title? thanks!

Use a JFrame not a JDialog.

Why my DropDownByKey can not display witn data???

//@@begin wdDoInit()
    //初始化任务查询下拉列表
     String contextPathQC = "ListBox.QueryCondition";
     ISimpleTypeModifiable queryListBoxItem = wdThis.wdGetAPI().getContext().getModifiableTypeOf(contextPathQC);
     IModifiableSimpleValueSet queryConditionVS = queryListBoxItem.getSVServices().getModifiableSimpleValueSet();
     String[] queryCondition = {"全部","等待","运行中","邮件错误","完成","已提取","终止","取消"};
     for (int i = 0; i < queryCondition.length; i++)
          queryConditionVS.put(queryCondition<i>, queryCondition<i>);
     //初始化DQ服务灾难恢复下拉列表
     List listMds = RepositoryManager.repList;
     String contextPathDQB = "ListBox.SystemBack";
     ISimpleTypeModifiable dqBackListBoxItem = wdThis.wdGetAPI().getContext().getModifiableTypeOf(contextPathDQB);
     IModifiableSimpleValueSet dqBackConditionVS = dqBackListBoxItem.getSVServices().getModifiableSimpleValueSet();
     for (int i = 0; i < listMds.size(); i++)
          dqBackConditionVS.put(((Repository)listMds.get(i)).mdmServer, ((Repository)listMds.get(i)).mdmServer);
these is the init code!!!

Are you passing String array in below line,I think you to pass just a string.
queryConditionVS.put(queryCondition, queryCondition);
And di u try to check if it works using the Strings in English.
And one more thing if are you trying to fill data from a node,why don't u try using DropdownbyIndex

Hi Experts,
I am having a tree table component in adf. I have set a folder image for the parent node. How can we set a document image for contents inside a parent node.
Thanks,

If I add artwork by dragging a jpg to the artwork area after selecting several rows, in some instances a single icon is created in the flipper; in others one is created for each song. Why? How can I get one image per album every time?

TS1398 Why does my iPad2 not display the WiFi icon?

Why does my iPad2 not display the WiFi icon? I have implemented ALL of the troubleshooting tips, but my WiFi icon is still missing, and it will NOT recognize the internet connection that I know to work on my computer and iPhone.

Try the following:
1. Reset the AirPlay devices
2. Reboot the router
3. Reboot the iPad
Note: The AirPlay icon is now in the Control Center

Can we display report by using Tree node?

hi all
can we display report by using Tree node if yes then plz guide me
sarah

In the object-navigator in the form there is node named "Reports". Create a new entry and name it "REPORT".
To call the report use something like the following code:
DECLARE
rep REPORT_OBJECT;
vcServer VARCHAR2(100);
vcJobId VARCHAR2(100);
vcUrl VARCHAR2(2000);
vcServer VARCHAR2(200) := 'PUT_YOUR_REPORTS_SERVERNAME_HERE';
BEGIN
rep:=FIND_REPORT_OBJECT('REPORT');
SET_REPORT_OBJECT_PROPERTY(rep, REPORT_FILENAME, 'put_the_filename_of_your_report_here');
SET_REPORT_OBJECT_PROPERTY(rep, REPORT_DESTYPE, CACHE);
SET_REPORT_OBJECT_PROPERTY(rep, REPORT_DESFORMAT, 'PDF');
SET_REPORT_OBJECT_PROPERTY(rep, REPORT_SERVER,vcServer);
vcJobId := RUN_REPORT_OBJECT(RO_Report_ID, PL_ID);
vcJobId := SUBSTR(vcJobId, LENGTH(vcServer) + 2, LENGTH(vcJobId));
vcUrl:= '/reports/rwservlet/getjobid' || vcJobId || '?server=' || vcServer;
WEB.SHOW_DOCUMENT(vcUrl, '_blank');
END;
