i have a jtable calendar program and i want the user to be able to click on the dates and i wrote a mouse listener and added it to the jtable nut its not firing .....what should i do my deadline is tomorrow....

without seeing any code, or any error message/stacktrace, bit hard for us to tell. If your deadline is tomorrow, well ... remember this next time: trying to get it done last minute usually blows up in your face.

Most likely, there's something wrong or missing in your code, but we can only speculate about that.

i wasnt trying to do it last minute...i have been on it for weeks
im just a beginner and research took up my time....and the handler class(mouseevent) works when i apply it to the scroll panel but doesnt work on the jtable

Your problem description is wrong.
I ran your code with a print statement in the mouseClicked method as it WAS being called. It's the setBackground that's not working - presumably because you have a custom cell renderer that sets the background to fixed values.

ps: I ran this on a Mac and the layout is a mess because you have used a null layout manager and chosen pixel sizes that are (presumably) OK on your machine, but absolutely not portable. That's why we have layout managers.

hey you are right the problem was with the setbackground function....
i have this other class(gui) that takes in the appointment details from the user and i added it to the mouse clicked method and it works...here is the code

 public void mouseClicked(MouseEvent event){
          // tblCalendar.setBackground(Color.BLUE);
           InputWindow inp = null;
            try {
                inp = new InputWindow();
            } catch (ParseException ex) {
                Logger.getLogger(CalendarProgram.class.getName()).log(Level.SEVERE, null, ex);
            }
           inp.setVisible(true);
        }

one more thing...after a cell is clicked on i want it to change colors...any ideas????

thanks for all the help james and stultuske...i have one last question and i wont bother u no more.....so how can should i display the appointment details the user puts in???? here is the code for the input window...

i want to make the enter button save all the details in an array or smthng for later display...when a user clicks on a date for the second time i want them to be able to view what they put in...help!!!!!!!!!!! lot to do no knowledge on hw to do it :(

I wouldn't start with the enter key yet, first start with buttons, and the listeners you have so far.
Have the information you enter stored (in the application in memory, and on closing the application, on your hard drive in an xml file (for example)).

That way, once you choose the same date a second time, you just have to load the previously entered information.

okay so i need to create a database and what ever the user enters must go there???? but i dont know how to handle xml in java...send me open source library links pls

you can create a database, but for now, I would start without one, just store the data in local files, txt or xml for instance.
There are tons of tutorials and resources to learn how to work with xml files.
Take a look over here.
