hi maheshexp,
thanks for your useful advices. regarding Qns 2, what do you mean? What i want is that the application must be able to grab the files/mp3. and this application is able to send these files/mp3 to a usb devices without storing this files into my PC system. how actually can it be implemented. thanks.
1. use a IDE that can generate GUI automaticaly. i sugesst JBuilder ... just drag, drop and code
2. use apache FileUpload library available here http://jakarta.apache.org/
3. here is a free library from IBM
http://www-106.ibm.com/dev
Using FileUpload you get a fileName, open a FileInputStream for it
and then open a stream for usb device and write the file content
this way you don't have to store the file temporary on the server

valipotor,
>>2. use apache FileUpload library available here http://jakarta.apache.org/
i think he needs to download the file, rather than uploading it
>1. use a IDE that can generate GUI automaticaly. i sugesst JBuilder ... just drag, drop and code
Net Beans has the same feature. Just make sure you understand the principals behind developing a gui otherwise you may find yourself having trouble even with the drag and drop. If you know how to use the awt layouts, then it should be enough to get you by.
Thanks alot for all these inputs. I will look through it and get back to you guys asap.
I have thought of using JBuilder, but I am afraid JBuilder will add some irrelevant codes into my program.
Regarding Qns 2, the scenario is that this:- I got a website which provide mp3 files. I want to streamdown this files through this Java apps and then connected to a USB devices. But I dont want this mp3 to be stored in my PC system. The Java apps will in charge of grabbing the mp3 and then transmit to the USB device.
Java has SecurityManager, but it is for protect the access to the vital machine resources.
It enables/disables you to write on the local filesystem & others (see the documentation).
If you are speaking about java code(bytecode) protection... mhmmh.
The bytecode must be executed over the JVM, so the class file must be "clear to read" for JVM.
In the net there are many code hider (like "retroguard"), but... no software is really secure protected. This is a mainstone of Computer Technologies.
Community, like Microsoft, could find any strategies to protect, but after a period some find the against-protect one's.
The only thing to do is to protege software using law (but the problems are the same).
Bye, Giant.

>>1st Qns:- Is there a simpler way to develop GUI using java? I find it very time-consuming developing GUI.
user swing components, u can also use AWT, but swing is better
>>2nd Qns:- I am planning to develop an application which act like a buffer, this buffer will grab the files/mp3 from website
buffer means u need storage space in ur webserver
>>3rd Qnd:- I would also like to have this apps able to communicate with the USB port. How can i do it?
using USB is system level programming, it can be done using JNI interfaces
