I'm studying Electronics
Engineering in the University of Rosario (Argentina) and am a beginner Java
programmer who needs detailed information and code examples about the use of the
Java Communications API (my final project includes the use of the RS 232
interface to share information between two PCs).
Sun Microsystems' documents
on this topic are not tutorials, the books I can get in my country don't cover
this sort of I/O and I can't afford to import a book from the USA ( since "1
dollar = 3 pesos" ).
Would you please send me any information of yours or
tell me where I could find it on the Internet?

|Compositing(image and movie) in Java
I would like to do some
compositing in Java. Currently I'm using QuickTime for Java to do it. It is very
easy. However I always get some runtime exception when I execute the program. So
I want to switch to pure Java. I want to play a movie as the background,
probably using JMF. Then do some animation with some images and text in front of
the movie. Is this possible? Any advice or sample program?
please help me
|JTabbedPane and focus issue
Maybe I'm just doing things a
bit different than anyone else and I'm wrong. Here's the deal: I have a focus
traversal policy for each frame in my app. When I used a personally-created
subclass of JTabbedPane it was trying to set focus on a component on a
non-visible tab. So I fixed that problem by not allowing focus to go to
non-visible tab panels.
Now I want, on a tab change, to set focus on the
first focusable component of the new tab. But at the time I get a change event
to hook this call the old tab is still visible and the second one isn't.
