You need to do the following before you run the code to implement on your machine:

Set the system DSN with name MominDB.mdb (its an microsoft access file).
Fill up the table named as CTS ( table name is CTS) from where all the data is been fetched.
Fill up the table until you get the scroller down. (This is the main issue) Scroller is getting overlaped.

Fast Snail, I have edited my code please have a look and assist me on it, Please. This is the second method I also have tried with DefaultTableModel if you want I can show you that code as well. Please let me know. — Umair7, Aug 24 '15 at 17:08
first create jtable with column names then add rows .using `jtablemodel.addRow():` — Madhawa Priyashantha, Aug 24 '15 at 17:12
I'll show you how I did that by using DefaultTableModel However, I need to create a new object every time that is nonsense thing that I am doing I wana get rid of that. I will show you the code and you tell me what is the alternate method for it — Umair7, Aug 24 '15 at 17:17
I have edited again by the method of DefaultTableModel, which is similar like what you have suggested, please have a look. On every new event I want to display a different data and want to clear the contents that were displayed on my previous event — Umair7, Aug 24 '15 at 17:19
row adding part is perfect only problem is your are creating a table and model every time ..you shouldn't add table creating code inside the button click method .create jtable and model just one time may be when gui start. and inside the button click event add rows to the existing table — Madhawa Priyashantha, Aug 24 '15 at 17:21
Yeah I tried that however, the new event data is appended at the end of the old event data and both are displayed a the same time — Umair7, Aug 24 '15 at 17:25
before you add data use `model.setRowCount(0);` to clear the table — Madhawa Priyashantha, Aug 24 '15 at 17:27
I have tried that as well but not getting result, can you please give a demonstration by editing my code. — Umair7, Aug 24 '15 at 19:02
You're asking @FastSnail to create a [mcve] for you, but since he's a volunteer, and you're the one asking for help, it is much more appropriate for you to create and post your [mcve] first, and then allow him to modify it if need be, to help you out. — Hovercraft Full Of Eels, Aug 24 '15 at 21:48
@Hovercraft Full Of Eels, If you able to understand my code then help me with this. — Umair7, Aug 25 '15 at 12:05
@Fast Snail, I have edited the code as per your input however, Its running but I am unable to see anything on my screen. Please help me — Umair7, Aug 25 '15 at 12:05
@Umair7: I'll better be able to understand things if you create and post your [mcve]. If you don't get a full answer soon, then you'll want to do this. — Hovercraft Full Of Eels, Aug 25 '15 at 16:24
@Hovercraft Full Of Eels, My code is really big to post here and to read I totally understand what do you mean, however, I want to spend time in research then to create Minimal, Complete, and Verifiable example. I will update my code for you for better understanding — Umair7, Aug 25 '15 at 16:32
I did not ask for your whole code, just enough to run and to show us your problem. — Hovercraft Full Of Eels, Aug 25 '15 at 16:40
I have edited my code, I will try to post a code which even you can run and see on your machine. In the mean time please have a look on this code, and see if you can conclude something. — Umair7, Aug 25 '15 at 16:50
Also, the volunteers on this site always appreciate it if posters put in the effort to post **well-formatted code**, something that you haven't yet done. Please fix this, else you're only making it harder for folks to read and understand what you've posted. — Hovercraft Full Of Eels, Aug 25 '15 at 21:37
Instead of pitching me on the format of the code I would rather appreciate the relevant conclusion to my question. Moreover, I don't think there is any problem in understanding the above code for a "Programmer". — Umair7, Aug 26 '15 at 10:19
Good, then since you're a "programmer", you've solved your problem, right? — Hovercraft Full Of Eels, Aug 28 '15 at 19:32
I was here for help on my issue, since you are unable and I mean "UNABLE" to answer my question, you started with offending words. You are just replying without any logical reason behind your words. if you have something of note then only speak else consider this experience as your failure. — Umair7, Aug 31 '15 at 10:24

You can try the following:

Make your model (dtm) a member field.
Remove setModel and scroller.add calls in the action listener.
Before your while loop - reset the data model to empty. You can call setRowCount(0) or getDataVector().clear().

Then see whether it works. Please post formatted code, so that we can read it well.

Sir, I have edited my code, please see and suggest If I have left any thing – Umair7 Aug 25 '15 at 12:26
@ KDM, If I am adding the scroller, table and setModel in a constructor (As I have done in above example) then my scroller does not work. – Umair7 Aug 25 '15 at 12:36
@Umair7 I don't see the modifications. Anyhow, if it works for you - it is correct :) – Dakshinamurthy Karra Aug 25 '15 at 12:42
If I dont create a new object for every listener I am unable to see anything on panel however, sql query still running, And if I create the objects of table and scroller in constructor, my scroller gets freezed. I am new to stack overflow I dont have much reputations to post screenshots here. Please help... – Umair7 Aug 25 '15 at 13:18
