Thanks a lot for responses (Bruce and Nicolas),
This Palm application is a simple form to be filled up in the field and
uploaded back to an Oracle database, wireless connection may be needed for
running some reports.
Java is being considered to comply with the rest of the platform but other
options are also seriously being looked at, like web clipping, C++ or VB,
even between the CE and palm.
Thanks for letting me know about your own experience Bruce, let me know
please if I could ask you more details on your own email.

Michelle

Hi Michele.  WRT books on the KVM and CLDC, I have "Java 2 Micro Edition:
Ultiimate Guide to Programming Handeld and Embedded Devices" by Eric
Giguere,
which is a pretty good book.

One thing he states at the beginning of chapter 3: "If in doubt do not use
Java...The reality is that Java on small devices is still an immature
technology
with a lot of room to improve and evolve...".  I believe this statement is
still
true.  We just finished developing a Java application for a Visor (same as
Palm), and there are a lot of business rules and somewhat complex data
structures, and as a result there are some performance issues.  Also,
printing
via the IR port is not supported with the J2ME profile we chose (KJava ---
btw,
stay away from KJava - it was a early version that is not supported by Sun).

If you're buiding an important application, I'd suggest going with C++ or C,
so
that you're guaranteed that the app will work as fast as it possibly can,
and
that all features are supported.  If you really want to use java (and there
are
reasons, amongst them portability and ease of development), I'd recommend a
proof-of-concept phase in which you can investigate some of the different
KVM's
out there (they vary in speed and features and development-debugging tools)
and
make sure that J2ME meets your requirements.

J2ME is gaining momentum and should be one of the tools of choice in the
future,
but right now, be careful.

Subject:  Any Book for CDC?



Hi all,
Can I ask if anybody knows of a good book on CDC/CVM and the Foundation
Profile?
Sun itself has these two books that concentrate more on KVM and CLDC.
I have been asked to evaluate options for an application for Handheld
devices (Palm most possibly) and am myself new to the subject, all your
ideas would be greatly appreciated.

Michelle
