How to implement edit time help like Eclipse, IntelliJ in Swing

Hi,
I am developing an DataBase query tool. In my application, there is a area for writing SQL command like select etc. I want to show the names of tables or fields when the user write a select keyword or give a dot(.) after giving a table name like Ecilpse shows the field names of particular class when we give the class name.

Hi,
You would need to add keyListener to the text component into which you are entering the query and listen for a particular keystroke. In your case it would just be a space character.
However I would you are going about this the wrong way. How do you plan to handle the fact that in a sql query the column names come first before the table names. I would suggest you have a wizard type gui where you first get the tables involves so you can fetch and display the column names.
Hope this helps.
cheers,

How to implement multiple Value Helps within the same Application ??

Dear Experts,
I want to implement multiple value helps in the same view.For that I have declared exporting parameters of type 'wdy_key_value_table.' within the component controller for each of the value helps.While I do activate and test the application I get the following error :
The following error text was processed in the system HE6 : A row with the same key already exists.
The error occurred on the application server hsdnt24s11_HE6_00 and in the work process 4 .

I dont know how to implement multiple value helps.Need your help on this.

Hi
Hint is : A row with the same key already exists it means , It is assigning the same value/Key to row and you are calling it at WDDOINIT so it giving error at the time of initialization .
Better way to do the coding at some event in view OR if not possible than just execute the first value help in wddoinit later clear all the value before gettig the other Value help. Code it at WdDoModify View to get its run time behaviour.

How to Implement a Time Limit Feature in an Online Test Application ?

I am creating an Online Test application. The time limit can be stored for a Test in the database.
How to implement a time limit such that when the test is started (user clicks on the Start button to go to the fragment containing the Questions) the time left is shown and the test ends (goes to home page) when the timer reaches zero.
Thanks

Hi,
timestamp is a date and thus cannot be used directly to determine seconds passed. So what you need to do is to build the difference between a saved time stamp and the current time.
http://docs.oracle.com/javase/1.4.2/docs/api/java/sql/Timestamp.html
So if you have two time stamps, then calling getTime() on each and building the difference gives you a value, which is millisecond. So to get this to an int value you divide it by 1000

Hi Sanjiv,
do you you mean expand the Help Menu => Pull Help or do you mean
EPSS => push Help?
in case pull help please tell me exactly which system GUI or EP and version you are using.
many different scenarios are possible.
Tom
P.S. Please take care of the name is Workforce Performance Builder or maybe in-official WPB.
many people ask in the HCM area for help, this is the reason why we do not observe all discussion.

How to implement this need help

I created a datacontrol for a named query which (using Ejb entity beans) which accepted a employee id and click on find show me the respected employee details in a table.
case 1: In one single page
when i added the form consisting of a single text box , button and the table to show the result of the find method in one single page it worked out perfectly,,,
case 2 : using 2 different pages
But then i tried adding only the form in one page named page1 and and the table to show the result in another page i.e page2 , Also in the command action of find button of page1 i asked it to redirect to page 2 and show result . But it never showed me any results..
Question :
1) How to implement case2 i.e to have a form on one page and the resultant table to be show on another page i.e When users sees first page he adds the employee id in text box and clicks find .The user then needs to be redirected to page2 and the result of search should be shown in table...
Can anyone guide me over this... ???

Hi,
you use a method on the EJB that takes a argument (e.g. the employee ID). You then put the method result set on page 2 (the method argument shall be pointed to a request or session attribute using EL : #{sessionScope.EmployeeId}
On the search page - when the user hits the search button - you set the attribute "EmployeeId" in the session before navigating to the next page

How to implement a time watch for an object

Greetings!
I have a container called TupleSpace which consists of elements of type Tuple. Among the attributes, the Tuple also has a "time to live" (the maximum amount of time its presence is allowed on the TupleSpace). After this amount of time passes it should be automatically deleted from the TupleSpace. My question is: what is the best mechanism to implement this ?
My solution so far looks like this:
public void removeExpiredTuple(){
// ts = instance of TupleSpace class
          for (int i = 0; i < ts.size(); i++){
               ITuple currentTuple = (ITuple) ts.elementAt(i);
               long tupleAge = System.currentTimeMillis() - currentTuple.getTimeSubmitted();
// currentTuple.getTtl() = retrieves the Tuple's "time to live"
               if (tupleAge > currentTuple.getTtl())
                    ts.remove(i);
     }but I am not at all satisfied with it
Thanks in advance for your answers

                    System.exit(1);

here is a simple demo of a Timer usage.
public class Scheduler{
    private Timer timer = null;
    private FTPClient client = null;
    public static void main(String args[]){
        new Scheduler(5000);
    public Scheduler(int seconds) {
        client = new FTPClient();
        timer = new Timer();
        timer.schedule(new fileTransferTask(), seconds*1000);
        timer.scheduleAtFixedRate(new FileTransferTask(client), seconds, seconds);
public class FileTransferTask extends TimerTask{
    private FTPClient client = null;
    public FileTransferTask(FTPClient client){
        this.client = client;
    public void run(){
        client.sendFile();
public class FTPClient{
    public void sendFile(){
         // code to send the file by FTP
}the timer will will schedule the "task": scheduleAtFixRate( TimerTask, long delay, long interval)
It basically spawn a thread (this thread is the class that you
implements TimerTask..which in this example is the FileTransferTask)
The thread will then sleep until the time specified and once it wake..it
will execute the code in the the run() method. This is why you want to
pass a reference of any class that this TimerTask will use (that's why
we pass the FTPClient reference..so we can invoke the object's
sendFile method).
