Foreword: Excuse me for
possible mistakes. English is not native language for me.
In this issue:
Hello dear friends!
Question: I am going to start applications development for wireless
devices. Could you guide me what I could use for that?
Answer: The production release of the J2ME Wireless Toolkit 2.0 is
now available. This version of the toolkit supports the MIDP 2.0 (JSR-118)
specification as well as the Wireless Messaging API (JSR-120), and Mobile Media
API (JSR-135) optional packages.
The Java 2 Platform Micro
Edition, (J2ME) Wireless Toolkit are sets of tools that provide application
developers with the emulation environments, documentation and examples needed to
develop Java technology applications targeted at CLDC/MIDP compliant mobile
phones and entry level PDAs. Two products are available depending on your needs.
Both tools are available at no charge to individual applications developers.
For developing
applications for MIDP 1.0 devices, use the J2ME Wireless Toolkit version
1.0.4_01.
For developing applications for MIDP 2.0 devices, use the J2ME Wireless Toolkit
version 2.0. The 2.0 version also includes built-in support for the Wireless
Messaging and Mobile Media APIs.
Below are some of the hot
features in J2ME Wireless Toolkit 2.0. You can get more detailed information
about the new toolkit by referring to the accompanying User's Guide and Release
Notes.
Support for MIDP 2.0
Support for WMA
Support for MMAPI
Solaris and Linux versions
Additional development features:
Integrated Over The Air emulation
Midlet Signing
WMA Emulation features for SMS and CBS messages
New skins for QWERTY and Media devices
Certificate management
Push Registry emulation
Monitoring for all protocols (HTTP(S), Socket, datagram, Comm, SSL,
SMS/CBS)
Compile and Runtime selection of API extensions (WMA, MMAPI)
New demo applications
Support for the ProGuard obfuscator
Note: The J2ME Wireless Toolkit 2.0 still includes all of the advanced
development features found in Wireless Toolkit 1.0.4_01 (Obfuscation support,
method profiling, memory and network monitoring, device speed emulation).

Question: Is it possible to use RSS ("Really Simple Syndication")
together with JSP?
Answer: Yes, SUN recently developed RSS Utilities package - a JSP Tag
Library to be used by anybody with a basic understanding of RSS, JavaServer
Pages, and HTML. The taglib is mostly geared towards non-technical editors of
web sites that use RSS for aggregating news content.
It contains a set of custom JSP tags which make up the RSS Utilities Tag
library, and a flexible RSS Parser.

Question: I use an old Java Tool from SUN. Today I read that SUN
started End Of Life Process for this Java tool.
What does it mean? Does it mean that when the process will be finished my tool
will stop to work? What is about customers?
Answer: Everything is Ok! Life continues and the tool will work 
During the EOL transition period, all announced products will be supported as
per existing customer support agreements. After the EOL transition period, these
products will no longer be supported by Sun. Products that have completed the
EOL process will be moved to the Archive area here:

Help
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?
Sincerely,
Jorge D'Agata

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?
Thanks in advance.

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.
