the problem of creating the component is solved. now one new problem
arose.....
once i create the component in the file and save it and close the window.
and after that i again try to open the file i am not able to load the
component.
wat i have done is i have serialized the image and overriden writeObject
and readObject methods...........i have serialized it by getting the
pixels from the imageData using the getResourceAsStream
method................
Please advise if i am wrong somewhere

Hi Pratik,
thanx for your concern. actually the problem is solved now. the problem
was i was not serializing the image data. i overrid the readObject and
writeObject and grabbed the pixels.........
Now a new problem has taken place. Now i am not able to move the component
from one location to another at that particular time. but when i save the
image and again load it the image is moved to the new location where i
dragged it earlier before saving........
i have used correct role and policies for it......
can anyone please tell which method i have to use setLocation and setSize
methods for it.........
Regards,
Harsh Singal
