Neutrino & Java

Hi!,

I’m still being quite ignorant about how to use Java & Neutrino. Maybe
there’s anybody there whocan give me a clue about how to implement for
instance, a very simple I/O resource manager (RM) that deals with a
consumer/producer issue. So, a client reads from the RM and the other writes
in it.

I know how to do it in GNU C/C++ for Neutrino but not in Java. By the way,
is there any kind of documentation about Java implementation in
Neutrino???

Cheers.

AFAIK there is no official Java for Neutrino…
all what you can so far - just play on with IBM J9 JVM using free Visual Age 4
Java Mobile Edition :wink:

Hi!

thanks Andrej!

I’ ve just begun some days ago to star using J9, that’s the reason of my
question. Just in case somebody has already started to do some work with
that.

Help!!! :slight_smile:)

Thanks

Neutrino may not host an ‘official’ Java, however IBM does support Neutrino
as one of it’s platforms for the J9 VM. And it’s VisualAge Micro Edition
(no “4” in the name, nor “Mobile”, AFAIK).

BTW, Juan has posted similiar questions in the vame (VisualAge Micro
Edition) forum on news.software.ibm.com (group: ibm.software.vame), and my
response basically was that he needed to learn how to do JNI, by reading
“Essential JNI” from Rob Gordon. Or don’t bother trying to implement a
resource manager in Java (which would involve lots of non-trivial JNI and
Java code), but simply separate out concerns: write the resource manager in
C, since this is a known quantity, and talk to the resource manager from
Java using java.io.File. I’ve done this to great effect in the past, I
think both in Java and IBM’s embedded Smalltalk …
