I am working on an application for nokia e71.I want to display an alert for a time interval between Locfinder.ex() function is called and it returns the location value.Do i need to create a separate thread?
I am very new to Java so still not clear with all the concepts.I am pasting my code here.Pleas give some suggestions.

you can just make Locfinder.ex() "sync" and in that function first line should be showProgressBar() and last line will be destroyProgressBar().Thats it.

I am trying to programmatically create Users with Internal Accounts as part of a testing system. The following code can not create an InternalLogin because there is not password hash set at object creation time.
Can a person + internal account be created using metadata_* functions ?
data _null_;
length uri_Person uri_PW uri_IL $256;
call missing (of uri:);
rc = metadata_getnobj ("Person?#Name='testbot02'", 1, uri_Person); msg=sysmsg();
put 'NOTE: Get Person, ' rc= uri_Person= / msg;
if rc = -4 then do;
rc = metadata_newobj ('Person', uri_Person, 'testbot02'); msg=sysmsg();
put 'NOTE: New Person, ' rc= uri_Person= / msg;
end;
rc = metadata_setattr (uri_Person, 'DisplayName', 'Test Bot #2'); msg=sysmsg();
put 'NOTE: SetAttr, ' rc= / msg;
rc = metadata_newobj ('InternalLogin', uri_IL, 'autobot - IL', 'Foundation', uri_Person, 'InternalLoginInfo'); msg=sysmsg();
put 'NOTE: New InternalLogin, ' rc= / msg;
run;

I ended up using Java to create new users.
A ISecurity_1_1 instance from MakeISecurityConnection() on the metadata connection was used to SetInternalPassword
Java ended up being a lot more clear coding wise.

In other words, Which Database tables do i need to look into for the mapping of a portlet to a page in an organization? If there is such a thing?! We are using Liferay 6.1.20
Apart from the marketplace portlet.
If you have access to the Database you can fire a simple query on the Layout table to know in what all pages your portlet is added:
SELECT * FROM Layout WHERE typeSettings LIKE '%my_WAR_myportlet%';
Also you can build a FinderImpl with service-builder to execute this query through a portlet and add that portlet to page to display in whatever format you want.
Below is another solution without deploying any portlet and without having access to the DB (tested on MySQL DB):
Go to Server Administration
Go to Script tab
Select Beanshell from the Language drop-down
Paste the following script code in the textarea and press the button execute:
import com.liferay.portal.kernel.dao.jdbc.DataAccess;
import com.liferay.portal.kernel.log.Log;
import com.liferay.portal.kernel.log.LogFactoryUtil;
import com.liferay.portal.kernel.util.StringBundler;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Iterator;
import java.util.List;
Connection con = null;
PreparedStatement ps = null;
ResultSet rs = null;
try {
con = DataAccess.getUpgradeOptimizedConnection();
// your custom query here
String sqlQuery = "SELECT * FROM Layout WHERE typeSettings LIKE '%my_WAR_myportlet%'";
out.println("SQL Query: "+ sqlQuery);
ps = con.prepareStatement(sqlQuery);
rs = ps.executeQuery();
ResultSetMetaData rsmd = rs.getMetaData();
int columnCount = rsmd.getColumnCount();
List rows = new ArrayList();
List columnLabels = new ArrayList();
columnLabels.add("Sr. No.");
for (int c = 1; c <= columnCount; c++) {
String cl = rsmd.getColumnLabel(c);
columnLabels.add(cl);
}
while (rs.next()) {
List row = new ArrayList(columnCount);
for (int c = 1; c <= columnCount; c++) {
Object value = rs.getObject(c);
row.add(value);
}
rows.add(row);
}
// --- formatting the results ---
out.append("<div class=\"lfr-search-container \"><div class=\"results-grid\">");
out.append("<table class=\"taglib-search-iterator\">");
out.append("<thead>");
out.append("<tr class=\"portlet-section-header results-header\">");
for (String value : columnLabels) {
out.append("<th>");
out.append(value);
out.append("</th>");
}
out.append("</tr>");
out.append("</thead>");
out.append("<tbody>");
boolean alt = false;
long resultsCount = 1;
for (List line : rows) {
out.append("<tr class=\"portlet-section-alternate results-row " + (alt ? "alt" : "") + "\">");
// for sr. no.
out.append("<td>");
out.append(resultsCount + "");
out.append("</td>");
resultsCount = resultsCount + 1;
for (Iterator iterator = line.iterator(); iterator.hasNext();) {
Object value = (Object) iterator.next();
out.append("<td>");
if (value != null) {
out.append(value.toString());
} else {
out.append("<span style=\"font-style:italic\">null</span>");
}
out.append("</td>");
}
out.append("</tr>");
alt = !alt;
}
out.append("</tbody>");
out.append("</table>");
out.append("</div></div>");
} catch (Exception exp) {
out.println("ERROR: " + exp);
throw exp;
}
finally {
DataAccess.cleanUp(con, ps, rs);
}
Please remember to change the string my_WAR_myportlet to your portletId
Needless to say you can modify the script to update the styles and can show selective columns. Also you can run any SQL query, just update String sqlQuery.
Hope this helps.
This is the solution, a free marketplace plugin that resolve your issue.
http://www.liferay.com/it/marketplace/-/mp/application/27156990
Here is a code to get all the portlets from the first column
ThemeDisplay themeDisplay = (ThemeDisplay) request.getAttribute(WebKeys.THEME_DISPLAY);
Layout layout = themeDisplay.getLayout();
LayoutTypePortlet layoutTypePortlet = (LayoutTypePortlet) layout.getLayoutType();
List<Portlet> portlets = layoutTypePortlet.getAllPortlets("column-1");
for (Portlet portlet : portlets) {
// print your portlet.getPortletId() or do whatever you need
}
[layout] is the table in which you can find out which portlets(typeSettings ) are deployed on which page
I am looking to create an editable label at an arbitrary position on the pane on which I am writing. I am under the impression that TextField or TextArea objects are what I could use to implement that capability. There is obviously more to it as I don't know how to position the object when I create it. I have found an example on the "Chaotic Java" website but I need to do a bit more work to understand what's going on there. http://chaoticjava.com/posts/another-javafx-example-the-editable-label/
I am looking for more input from this group.
(There are no errors because I have not written any code.)
I was kind of curious about how to achieve this, so I gave it a try. This is what I came up with.
The approach used is pretty the same as that suggested by James in his comment:
I would start with a Pane, . . ., TextFields to represent text while being edited. Register mouse listeners with the Pane and Text objects, and use the layoutX and layoutY properties to position things . . . just to use text fields, and to use CSS to make them look like labels when not focused and text fields when focused.
The only significantly tricky part was working out how to correctly size the text fields as the Text inside the text field is not exposed via public API to allow you to listen to it's layout bounds. You could perhaps use a css lookup function to get at the enclosed Text, but I chose to use a private sun FontMetrics API (which may be deprecated in the future), to get the size of the text. In the future with Java 9, you should be able to perform the task without using the private API.
The solution doesn't try to do anything tricky like deal with multi-format or multi-line text, it is just for short, single line comments of a few words that can be placed over a scene.

If you have time, you could clean the sample implementation up and donate it to the ControlsFX project.
You can use a function of label: setGraphic().
Here is my code:
public void editableLabelTest(Stage stage){
Scene scene = new Scene(new VBox(new EditableLabel("I am a label"),
new EditableLabel("I am a label too")));
stage.setScene(scene);
stage.show();
}
class EditableLabel extends Label{
TextField tf = new TextField();
/***
* backup is used to cancel when press ESC...
*/
String backup = "";
public EditableLabel(){
this("");
}
public EditableLabel(String str){
super(str);
this.setOnMouseClicked(e -> {
if(e.getClickCount() == 2){
tf.setText(backup = this.getText());
this.setGraphic(tf);
this.setText("");
tf.requestFocus();
}
});
tf.focusedProperty().addListener((prop, o, n) -> {
if(!n){
toLabel();
}
});
tf.setOnKeyReleased(e -> {
if(e.getCode().equals(KeyCode.ENTER)){
toLabel();
}else if(e.getCode().equals(KeyCode.ESCAPE)){
tf.setText(backup);
toLabel();
}
});
}
void toLabel(){
this.setGraphic(null);
this.setText(tf.getText());
}
}
I have a Tabpane with multiple tabs.
I want to re-position tabs by just dragging them at a particular position(just like the way we are able to arrange tabs in browser.)
Is there any way i can achieve it?
We achieved it in a slightly different way.Instead of drag/drop feature we provided the move left/move right functionality on tab context menu which in turns moves the tab.
We wanted to have this feature on priority so implemented it with this workaround for now.
Code snippet for MoveRight:
public void moveRight() {
protected TabPane workBook;
int cTabIndex = bem.workBook.getTabs().indexOf(bem.activeSheet);
int tabCount = workBook.getTabs().size();
if (tabCount > 1 && cTabIndex > 0) {
workBook.getTabs().remove(bem.activeSheet);
workBook.getTabs().add(cTabIndex - 1, bem.activeSheet);
}
}
I've implemented a class that handles both draggable and detachable tabs - more details here. The implementation is not the tidiest, nor the most resilient but works pretty well for me in the simple cases I've tried so far. I've deliberately kept everything in the one class to make it easier for others to copy / use / modify as they see fit.
The basic concept that I'm using (arguably mis-using) is that the graphic you can set on a tab can be any node, not just an ImageView (or similar.) So instead of using the setText() on Tab directly, I'm not adding any text at all, just setting the graphic to be a Label containing the desired text. Now that the label is present in the tab header (and is pretty much the tab header spacially), that makes it much easier (and skin-independant) to grab the global co-ordinates of each tab header in the pane. From then it's just a case of some relatively simple positioning logic to work out when to detach tabs into a new window, when to re-add them and when to reorder them.
Of course, this isn't an ideal solution but unfortunately I haven't seen much else on the subject!

I just found out that this has been implemented in JavaFX 10.
tabPane.tabDragPolicy = TabPane.TabDragPolicy.REORDER
...does the trick.
Update Feb 2016
There is an open feature request you can use to track implementation:
JDK-8092098 [TabPane] Support for draggable tabs
The feature request is currently scheduled for implementation in Java 9. Patches for obtaining drag and drop functionality are attached to the feature request.
Drag and Drop for tab headers is not implemented in the base JavaFX 2.2 platform.
Until that is implemented in the standard JDK, you will need to implement the feature yourself using JavaFX's Drag and Drop functionality. A similar feature is implemented for dragging table column headers, so perhaps you could look to the TableColumnHeader.java code for inspiration in implementing your feature.
Should you implement it (if you wish) you can contribute the modifications back to OpenJFX via patches to the TabSkin.java source.
A very descriptive answer can be found where you can create custom tabs for the same:
http://0divides0.wordpress.com/2010/10/21/movable-tabbed-panes-in-javafx/
A JavaFX cooked solution is hard to find as dev blog for the same states that such functionality is not present for Tabs and they plan to incorporate later.
http://grokbase.com/p/openjdk/openjfx-dev/123fq9k310/draggable-tabs
The following code shows how to solve the problem in a very simple way without tricks.
.....
.....
Tab tab1 = new Tab("Tab1");
Tab tab2 = new Tab("Tab21");
TabPane tabPane = new TabPane(tab1, tab21);
root.getChildren().add(tabPane);
....
....
System.out.println("Tabs size()= " + tabPane.lookupAll(".tab").size());
tabPane.lookupAll(".tab").forEach(t -> {
System.err.println("tab.bounds = " + t.getLayoutBounds());
});
You can get an access to other areas of TabPane by using style classes such as tab-content-area, tab-header-area, tab-header-background, headers-region, control-buttons-tab. Just use lookup or lookupAll methods of TabPane
So, I made a class that takes arrays and calculates a value from them. I then decided (unknowingly) to incorporate it into a GUI interface. All went well until I noticed this strange error; one of the jtextfields (prarie) would not store text while the other (yard) does.
I looked around and found my problem similiar to mine on this site;
Updating text in a JTextField
But he had one that doesn't work at all, where I have one that works and one that doesn't.
The Code is here (it's a bit long, but most of it is GUI), so hold your breath!:
import java.awt.GridLayout;
import javax.swing.Box;
import javax.swing.JCheckBox;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.JTextField;
public class Window {
/**
* #param args
*/
private static int numb;
private static double micro, centi;
private static JTextField[] yard,prarie;
private static double[] charges,distances;
public static void main(String[] args)
{
//create a small dialog window to take in number of charged objects
JPanel startup = new JPanel();
JTextField many = new JTextField(5);
startup.add(many);
int result = JOptionPane.showConfirmDialog(null,startup , "Please Enter How Many Charged Objects are Being Evaluated", JOptionPane.OK_CANCEL_OPTION);
many.requestFocusInWindow();
//once ok is clicked, then the number input will be stored under 'numb'
//then proceed to inputFields
if (result == JOptionPane.OK_OPTION)
{
numb = Integer.parseInt(many.getText());
inputFields();
}
}
//this window opens the various JTextFields for input
public static void inputFields()
{
//top JTextFields
yard = new JTextField[numb];
JPanel chargePanel = new JPanel();
for(int x=0;x<numb;x++)
{
yard[x] =new JTextField(5);
chargePanel.add(new JLabel("Charge "+ Integer.toString(x+1)+":"));
chargePanel.add(yard[x]);
chargePanel.add(Box.createVerticalStrut(15)); // a spacer
}
//bottom JTextFields
prarie = new JTextField[numb-1];
JPanel meterPanel = new JPanel();
for(int x=0;x<numb-1;x++)
{
prarie[x]=new JTextField(5);
meterPanel.add(new JLabel("Meters "+ Integer.toString(x+1)+":"));
meterPanel.add(new JTextField(5));
meterPanel.add(Box.createVerticalStrut(15)); // a spacer
}
//JCheckBoxes
JCheckBox isMicro = new JCheckBox("Charges are in terms of microCoulombs");
JCheckBox isCm = new JCheckBox("Distances are in terms of centiMeters");
JPanel chechBox = new JPanel();
chechBox.add(isMicro);
chechBox.add(Box.createVerticalStrut(20));
chechBox.add(isCm);
//Paste them all together into one window
GridLayout gufi = new GridLayout(3,1);
JPanel host = new JPanel(gufi);
host.add(chargePanel);
host.add(meterPanel);
host.add(chechBox);
int result1 = JOptionPane.showConfirmDialog(null, host, "Please Enter Charge and Distance Values", JOptionPane.OK_CANCEL_OPTION);
//if ok is clicked, then go to 'printArr()' to print the JTextFields
//then go to assign the values from the JTextFields to private double arrays 'yard' and 'prarie'
if (result1 == JOptionPane.OK_OPTION)
{
micro = (isMicro.isSelected())? Math.pow(10, -6): 1;
centi = (isCm.isSelected())? .01: 1;
printArr();
assign();
}
}
//a makeshift method to print the value from the JTextFields
//to fix the problem of why prarie wouldn't store numbers
public static void printArr()
{
System.out.println("Charges are:");
for(int x=0;x<numb;x++)
System.out.print(yard[x].getText() + " ");
System.out.println("Distances are:");
for(int x=0;x<numb-1;x++)
System.out.print(prarie[x].getText() + " ");
}
//assigns values from JTextFields to the private double arrays 'yard' and 'prarie'
public static void assign()
{
try {
charges = new double[numb];
for(int x=0;x<numb;x++)
charges[x]=micro*Double.parseDouble(yard[x].getText().trim());
distances = new double[numb-1];
for(int x=0;x<numb-1;x++)
distances[x]=centi*Double.parseDouble(prarie[x].getText().trim());
} catch (NumberFormatException e) {
e.printStackTrace();
//inputFields();
}
calculate();
}
public static void calculate()
{
JPanel sample = new JPanel();
JTextField whichOne = new JTextField(5);
sample.add(whichOne);
int result = JOptionPane.showConfirmDialog(null,sample , "Please Enter Which Charged Object thy Wishs For", JOptionPane.OK_CANCEL_OPTION);
whichOne.requestFocusInWindow();
if (result == JOptionPane.OK_OPTION)
{
int target = Integer.parseInt(whichOne.getText());
}
}
}
Anyone who runs the code and takes the time to enter dummy values will see that 'yard' stores values while 'prarie' does not. Why is this?
*I'm pretty sure I'm overlooking obvious (as always).
Change:
meterPanel.add(new JTextField(5));
to:
meterPanel.add(prarie[x]);
in the for loop for the prarie textfields
