Unable to run pgm. when in jar....

[robin singal]

Hi

I am using 4 Jframes and correspondigly 4 java classes for them. The program runs fine. But when i package it in jar file while giving the manifest info with the mainclass; the first frames runs ok but when i press submit button what happens is i create the object of another class and this is where the program gets stuck what could be the reason???
The constructor of the class which is called contains the tools to make the 2nd frame. But it does not event enters the constructor.

I am extending JFrame in all the classes and using ContentPane and adding componenets to it. and i am doing all this in the constructor of each class.


Thanks.
Robin

What exactly do you mean by "gets stuck"?

[robin singal]

By get stuck i mean :

I am using setTitle() to know exactly where i am in the code...
So after the setTitle() the control goes to the formation of an object which is assigned to the static variable of that class type...
But the control does not go into the constructor of that class whose object is created. Event i have user setTitle in exception there is also no exception raised.
Why the program that runs in console does not run with the jar file??

Just to ellaborate the situation... :

public class MainClass extends JFrame implements ActionListener,ItemListener
{
public static Otherclass oc;
 
public MainClass()
{
}
...
setTitle("before otherclass");
oc = new Otherclass();
...
catch(Exception e)
{
setTitle("Exception");
}
..
}
 
public class Otherclass extends JFrame implements ItemListener,ActionListener
{
..
public Otherclass()
{
 
}
..
..
}

Now the Otherclass constructor contains the code to make another frame.
by getting contentPane and setting layout and adding the required components.
But the Jframe does not appear but it does when i run the program in console??///

Thanks
