java exception handling whats the difference between the two styles pasted here?
Java

the first one is from a book which looks very cryptic/complex to me ,second one is the way i have seen people around me write including me :) ,also for the first style eclipse is showing that the catch "IOException openx" block is handing the exception for part where read and write is happening viz


while ((len = is.read(buf)) >= 0)
out.write(buf, 0, len);

.Does it mean catch "IOException iox" is useless code?


first style.


File file = new File("hsjdhsaj");
InputStream is = null;

EJB help, very confused with gui's and JFrames with J2EE
Java

Hi im in need of some help with a J2EE application im working on. I need to develop a JFrame front-end GUI client that will talk to the server, however i am not sure how to use JFrame to invoke methods on the server. This is mainly because im struggling to understand how I can call a method on the client side that will call a method on the server side when it appears to me that the client doesn't have a handle on the server-side (If that makes sense?)
I have crawled the web for some examples(including sun) but I still cannot find a tutorial.
