I have an applet. I am drawing lines on it. The code of my applet is as follows:

I want to make the ending X and Y coordinates of each line as starting X and Y coordinates of the next line. In this way I would be able to draw a continuous line on applet. I am stuck on this issue. Somebody can help me to resolve it. Thanks

Hi, I have an applet. Its size is about 2000 x 1500 and embedded in a JSP page. When I call it in browser, horizontal and vertical scroll bars appear. It always starts from top left corner and then I go to my desired place inside the applet. I want to open it with my preferred location. May be from center or from right side. I am not talking about the applet alignment. I am talking about specific location inside the applet. Is it possible? If yes then please guide me how I can achieve? I googled it but did not find the answer. Thanks

Hi my dear fellow!!!
I am making a plot in my mind for resolving a situation. Suppose, I have a web form with a field Department. I want to add Sub Departments(unknown number) of one Department and then further Sub Sub Departments(unknown number) of one Sub Department. How I will make a form and how I will add this data in attached database. I have one solution:
One Department field with a button to add any sub department if any. By clicking on button, a new row will be generated with another text field and new button. In this way, it will go on. Tree like structure.
But I have another solution, JSF Tree to add or delete entries on the run time. But the problem is that I am unable to find any example of JSF tree like structure populated from database and in which we can add or delete entries on run time and on the same time these entries may also be stored in database.
Can you please give me right direction so that I can choose the professional approach for resolving this situation.

Hi everybody
I am facing a situation in which I have to print those values which have not chosen by the user. For example

Out put of this code is
In if condition I have mentioned 5,6 and 7 so these are not printing. But if I get these values from database like

Now suppose id now contains 5,6 and 7 and I want to print other values may be from 1 to 100. Then how I will handle all these things in one program.
Actually I want to show only those values which have not chosen by the user. Please help me in this regard. Thanks.
