you have to create manifest file

in that manifest file you have to mention...

yea thanks i will try that first..

i dont have any idea about server socket thats why looking for alternate solution....

here is my code...


try {
// Get a file channel for the file
File file = new File("filename");
FileChannel channel = new RandomAccessFile(file, "rw").getChannel();...

yea i have used all these... but if i rename the jar file means its worthless... its again opening multiple instances

Thanks alot Ezzaral (http://www.daniweb.com/forums/member166824.html)

this file lock concept working fine.

thanks alot...you made my work ease by your idea.

Hi guys...

Is it possible to stop opening multiple instance of a jar file...

I just want to open my application only one (only one instance) at a time.

just check out the manifest file

In that manifest file specify your main class correctly. then it will work fine

I know that, But my question is what is the class for view and what is the class for model and what is the class for controller in MVC pattern. I have referred somw materials but i couldnt get the...

Hey guys.,
I just want to know about the MVC pattern in java swing.

up to my knowledge i knew ...... Model is used for storing information like Scrollpane height=50 width=60 like that

and...

webserver doesnt support business logic

whereas application server support business logic

and

Everything in web server must be achieved programmatically

where as in application...

this.setUndecorated(true);
boolean undecorated = this.isUndecorated();
this.setLocationRelativeTo(null);

with this code in java swing you can hide the frame

You can use decomiler to get java source code from the classes available in jar file...

there will be a exe called JAD with that you can decompile the classes in to source codes

you are exactly correct Josh

what is mean by Game of Life?

what do you mean exactly??

just create imageicon like this

Icon icon = new ImageIcon("fish20.gif");

and add it...in you button

JButton bstop = new JButton("STOP",icon);

How can you say this??? that my post is at fault of being cryptic

can you explain??

with the telephone number cant you find out the address???

did you tell your telephone number??

may be with the tele phone number you can trace the person's address easily...

just use this single line

Date thedate=new Date();

and print it....

System.out.println(thedate);

i think you have to update your current jar file..

You have to use the following code

jar uf currentfilename.jar updatefilename.jar

just use this command then both jar files can be made...

better search in google...
