SetLocationRelativeTo(null) not working

I'm trying to use setLocationRelativeTo(null) to center a JFrame however it's not working?
I'm using it elsewhere to do the same and it works, but this doesn't and the only difference is that it's being run in a separate thread. Why isn't it working properly?
I say properly, because it's not displaying it in the top left, but is to the bottom right of the center.
Please help
Thanks

... it's not displaying it in the top left, but is to the bottom right of the center.In other words, if you shrink the size of the frame to some extent by dragging in the lower right corner (possibly by a lot) then the frame will be centered, albeit sized too small?
It sounds as if the frame is getting modified after setLocationRelativeTo(null) is getting called. You mention that this is getting called on a thread? Why? And if really needed, how are you doing it? It's possible that the frame is being modified in another thread before it's shown.
Think of it this way: the frame is a certain size (really small), you then tell it to center itself (which it does properly while it still hasn't been shown yet), and then the frame gets bigger by adding components to it. What will happen is that the upper-left corner will remain in place, and the frame will grow out down and to the right.
Of course, this is all just a guess since you didn't provide an SSCCE.

Left Outer Join & IS NULL Not Working

In a Data Flow Query element I am using a Left Outer Join to correlate two tables. In order to eliminate rows in which the Left Outer Join found a match with the Right table I am using IS NULL in the Where clause. Unfortunately IS NULL doesn't seem to return true when the NULL is caused by a lack of a match on a Left Outer Join. Has anybody been able to work around this?

Use not is NULL in next query after the join.
A source 1 ---
C (join query) ----- D (filter condition IS NULL)
B source 2 ---

TextField setText(null) not working

Very simply put, I want a text field that when you type in it, it stores the character in a global String variable but doesn't actually display it. I know there are several ways of doing this, including a PasswordField, but this is purely for understanding purposes only.
String str = "";
private void txtLineKeyPressed(java.awt.event.KeyEvent evt) {
    char key = evt.getKeyChar();
    str = str + key;
    txtLine.setText(null);
}When typing "asdf" produces (caret is represented by |):
a|
s|
d|
f|I want to understand why txtLine.setText(null) clears the field BEFORE the letter is added to the field and possibly find out if there's a way (using TextField only) to accomplish this. I had a problem earlier with the enter key producing a line break at the end of all my lines and realized I was using a TextArea that caused the problem. Am I doing something similarly wrong?
--dorky

I want to understand why txtLine.setText(null) clears the field BEFORE the letter is added to the field Read up on how KeyListeners work. Three events are fired. The Document is updated on keyTyped(), which is generated after the keyPressed() event.
If you need further help then you need to create a [Short, Self Contained, Compilable and Executable, Example Program (SSCCE)|http://homepage1.nifty.com/algafield/sscce.html], that demonstrates the incorrect behaviour.
Don't forget to use the Code Formatting Tags so the posted code retains its original formatting. That is done by selecting the code and then clicking on the "Code" button above the question input area.
Also, the better way to do this is to use a DocumentFilter, not a KeyListener then you wouldn't have this problem. Read the Swing tutorial which has a working example of how to use a filter.

ForeignKeyDeleteAction=null not working with Kodo 4.1.2 and Mysql 5

Hello,
i am trying to use Kodo 4.1.2, together with mysql 5.0
my kodo.properties says:
openjpa.jdbc.MappingDefaults: jdo(ForeignKeyDeleteAction=null)
and i am expecting an sql-statement something like:
ALTER TABLE mytable ADD FOREIGN KEY (bar) REFERENCES othertable(foo) ON DELETE SET NULL;
but all i got is:
ALTER TABLE mytable ADD FOREIGN KEY (bar) REFERENCES othertable(foo);
Kodo 4.0 didn't have any problems with that. Also, in Kodo 4.1.2 other ForeignKeyDeleteActions (like 'cascade' oder 'default') are working like expected.
What am i doing wrong? Where can i find some upgrade instructions? Is this a bug?
Thanks in advance,
Markus

If the same exact app and code works with 4.0 with the same ForeignKeyDeleteAction setting, I suggest that you open a case with support.
This property hasn't changed since 4.0

CustomAttributeX -ne $null not working in -RecipientFilter

I am trying to create a dynamic distribution Group that will only return users who have CustomAttribute9 with numeric string and exclude any users who do not have that attribute populated. Here is my filter
New-DynamicDistributionGroup -Name GCI-AaronPTest -RecipientFilter {(RecipientType -eq 'UserMailbox') -or (RecipientType -eq 'MailUser') -And (CustomAttribute9 -like '0*') -and (Customattribute9 -ne $null)}
This is still returning users who have blank field for CustomAttribute9. Any help would be appreciated.

Hi,
I recommend you try the following command and check the result:
New-DynamicDistributionGroup -Name GCI –Alias GCI -RecipientFilter {(RecipientType -eq 'UserMailbox' -or RecipientType -eq 'MailUser') –And (CustomAttribute9 -like '0*' -or Customattribute9 -ne $null)}
Hope this helps!
Thanks.
Niko Cheng
TechNet Community Support
(RecipientType -eq 'UserMailbox' -or RecipientType -eq 'MailUser') –And (CustomAttribute9 -like '0*' -or Customattribute9 -ne $null)
this will include all mailbox or mail user which have customattribute9 other than like '0*' too .
so , replace just -or with -and in
(CustomAttribute9 -like '0*' -or Customattribute9 -ne $null)
to achieve the result.

Help with After Effects? Null Layer and Text not working?

In after effects cs5.5 on mac, im motion tracking as normal, and the track works fine, then when i add the null layer and edit the tracking target to the null layer, the screen goes black, and all i can see is the null layer as a red box moving along the motion track path (i cant see the path) also, whenever i try to add text, (which im trying to motion track via attatching to the null layer) the text is invisible, when the screens black, all i can see is the wire frame of the text next to the square null layer, im pretty new to after effects, but im following tutorials as i should, and its just not working as it shows in all the videos ive tried, please help!

Check whether you have wireframe mode enabled/ Live Update disabled. Sounds like one of those cases. Other than that this could be OpenGL issues, so turn it off in the prefs. Also check your comp size vs. the size of the footage you are tracking. Tracking works relative to the layer, so if the comp is too small, the values would be so large they end up being outside the comp.

You are calling changeButtonColor(frame.getComponents()) before you add the JScrollPane to the content pane.
But why not just move this to the button creation loop?
button = new JButton("button" + num);
button.setBackground(Color.LIGHT_GRAY);
button.setBorder(BorderFactory.createLineBorder(Color.LIGHT_GRAY));

Source data lines don't play the file when you open them, you have to manually read data from the AudioInputStream and write it to the SourceDataLine...and you're not doing that.
You essentially walked into the bathroom, lifted the toilet seat and unzipped your pants...and wondered why the toilet wasn't making that "I'm peeing" sound. It's because you didn't start actually moving urine from your bladder to the toilet...

TableChanged() does not work with parrent table reference

Hi,
I used this example http://www.javalobby.org/articles/jtable/ where the cells refocus after updating, but I have rewrote it to my needs and the program throws nullpointerexception when I update any cell:(
here is the tableChanged part of code:
    public class InteractiveTableModelListener implements TableModelListener {
        public void tableChanged(TableModelEvent evt) {
            if (evt.getType() == TableModelEvent.UPDATE) {
                int column = evt.getColumn();
                int row = evt.getFirstRow();
                System.out.println("updated row: " + row + " column: " + column);
               if((column + 1) >= model.getRowCount()){
                  table.removeColumnSelectionInterval(column,column);
                }else{
                  table.setColumnSelectionInterval(column + 1, column + 1);
                table.setRowSelectionInterval(row,row);
}the table reference worked in the exaple but doesnt work in my program:(
here is the init of the table in function initComponent:
        tableModel.addTableModelListener(new InteractiveTableModelListener());
        TableSorter sorter = new TableSorter(tableModel);
        JTable table = new JTable(sorter);the class is on the same level as the function
i have searched all the internet for this with no results:(
thank you for your advice!

Yes, you are right, I wrote this post in a hurry and exhaused, that it does not work.
I'm trying to write out a data file (now only a vector of data) in a JTable and I want to edit the rows and after I submit text in a cell, I want the caret to move one cell right, so the user can write another text, just like in MS Excel. At the end of the row the caret disapears but does not create another row.
And I have problems with variable JTable table in the inner class that contains method tableChanged().
Well After making an example I realized it worked and then I checked the example line by line and found out that I declare another JTable with the same name in the table initializing method,
Then the variable couldnt work in tableChanged method... It was empty...
I used your example from thread, you advised me:
import java.awt.*;
import javax.swing.*;
import javax.swing.event.*;
import javax.swing.table.*;
public class TableProcessing extends JFrame implements TableModelListener
     // here I declare the table
        protected JTable table;
     public TableProcessing()
          String[] columnNames = {"Item", "Quantity", "Price", "Cost"};
          Object[][] data =
               {"Bread", new Integer(1), new Double(1.11), new Double(1.11)},
               {"Milk", new Integer(1), new Double(2.22), new Double(2.22)},
               {"Tea", new Integer(1), new Double(3.33), new Double(3.33)},
               {"Cofee", new Integer(1), new Double(4.44), new Double(4.44)}
          DefaultTableModel model = new DefaultTableModel(data, columnNames);
          model.addTableModelListener( this );
                // here I declare it again, which is a MISTAKE
          JTable table = new JTable( model )
               // Returning the Class of each column will allow different
               // renderers to be used based on Class
               public Class getColumnClass(int column)
                    return getValueAt(0, column).getClass();
               // The Cost is not editable
               public boolean isCellEditable(int row, int column)
                    int modelColumn = convertColumnIndexToModel( column );
                    return (modelColumn == 3) ? false : true;
          table.setPreferredScrollableViewportSize(table.getPreferredSize());
          JScrollPane scrollPane = new JScrollPane( table );
          getContentPane().add( scrollPane );
      * The cost is recalculated whenever the quantity or price is changed
     public void tableChanged(TableModelEvent e)
          System.out.println(e.getSource());
          if (e.getType() == TableModelEvent.UPDATE)
               int row = e.getFirstRow();
               int column = e.getColumn();
               if (column == 1 || column == 2)
                               // AND here is not initialised - throws NullPointerException
                    TableModel model = table.getModel();
                    int     quantity = ((Integer)model.getValueAt(row, 1)).intValue();
                    double price = ((Double)model.getValueAt(row, 2)).doubleValue();
                    Double value = new Double(quantity * price);
                    model.setValueAt(value, row, 3);
     public static void main(String[] args)
          TableProcessing frame = new TableProcessing();
          frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
          frame.pack();
          frame.setLocationRelativeTo( null );
          frame.setVisible(true);

.jar file is not working properly :developed in NETBEANS

Hi Gurus,
i am using NETBEANS IDE 7.2.
i am developing a project that interacts with databases 10g and COM ports of machine , these all processes are performed by .bat file which i am trying to run from jFramform , code works perfectly .bat file is also called perfectly when i run the project using F6 from the NETBEANS, for testing i placed some dialogue boxes on the form to test it ,
but when i run executable .jar file , form run successfully and dialogue box works perfectly but .bat file is not called by executable .jar file.
this is how i call the .bat file...
String filePath = "D:/pms/Libraries/portlib.bat";
        try {
          Process p = Runtime.getRuntime().exec(filePath);
        } catch (Exception e) {
            e.printStackTrace();
and below is the contents of portlib.bat file
java -jar "D:\SMS\SMS\dist\SMS.jar"
you must probably ask why i am calling a .jar file using .bat file .
reason is that this .jar project sends message using GSM mobile , System.exit(); is compulsory to complete a job and then do the next one ,
if i use the same file to execute this job it makes exit to entire the application (hope you can understand my logic).
that's why i use extra .jar file in .bat file , when single job is completed .bat exits itself and new command is given.
Problem is that code is working perfectly in NETBEANS when i run the project but when i run .jar then .bat file is not working ,
thanks.

Thanks Sir ,
You need to first test an example that works like the one in the article.
There are plenty of other examples on the web - find one you like:
http://javapapers.com/core-java/os-processes-using-java-processbuilder/
I tried this one.
try {
            ProcessBuilder dirProcess = new ProcessBuilder("D:/SMS/SMS/Send_message.bat");
             File commands = new File("D:/SMS/SMS/Send_message.bat");
             File dirOut = new File("C:/process/out.txt");
             File dirErr = new File("C:/process/err.txt");
           dirProcess.redirectInput(commands);
             dirProcess.redirectOutput(dirOut);
           dirProcess.redirectError(dirErr);
             dirProcess.start();
        } catch (IOException ex) {
            Logger.getLogger(mainform.class.getName()).log(Level.SEVERE, null, ex);
as instructed in the article i compiled both the projects at same version or sources and libraries which is 1.7
here is my version details
C:\>javac -version
javac 1.7.0_07
C:\>java -version
java version "1.7.0_07"
Java(TM) SE Runtime Environment (build 1.7.0_07-b11)
Java HotSpot(TM) Client VM (build 23.3-b01, mixed mode, sharing)
inside the NETBEANS IDE c:\process\err.txt remains empty and code works perfectly , but when I run executable .jar file( by double clicking on that file in dist directry) then c:\process\err.txt becomes full with this error text and there is no response from calling D:\SMS\SMS\send_message.bat
here is the error text
java.lang.UnsupportedClassVersionError: sms/SMSMAIN (Unsupported major.minor version 51.0)
