[Javaosc-development] javaosc for J2ME

[Martin K. <mk...@iu...>]

Hello guys,
I made a quick port to J2ME using CLDC 1.1 and MIDP 2.0 for Java mobile 
phones.

Actually almost everything worked as I expected, the "largest" portion 
to re-implement was the transport code (OscPort).
The only class that was missing in MIDP 2.0 was the BigInteger class, 
which I fortunateley found as a pure Java implementation on the net.
A part from that the rest of the code was pretty portable, I needed to 
apply a few changes to the way Vectors were used (addElement() instead 
of add() and copyInto() instead of toArrray(). This can be easily ported 
back to the J2SE javaosc, which actually allows to use the same code 
base for all.

Although the UDP transport is fully functional right now, I don't see 
any point of paying a mobile phone provider for transmitting OSC 
messages to a device next to myself, so I will implement something like 
a OscPortInBT and OscPortOutBT in order to allow local Bluetooth 
communication. Maybe the class hierarchy for the transport layer could 
be changed accordingly to something like:

            OscPort
             |    |
      OscPortIn  OscPortOut
            |     |
   OscPortInUDP  OscPortOutUDP
   OscPortInTCP  OscPortOutTCP
    OscPortInBT  OscPortOutBT


If you want I can add the TCP layer for J2SE and UDP/TCP layer for J2ME 
right away, I will probably need some time to do the Bluetooth part I 
reckon.

I have an important request regarding the portability of javaosc.
Right now it seems that javaosc is compiling on J2SE as well as on J2ME 
Personal profile (based on JDK 1.3.1) and on J2ME MIDlet profile.
I didn't try it, but I reckon it even compiles on JDK 1.1
This is really great like that, and I think with little effort this 
portability could be maintained in the future changes to javaosc.

cheers,
Martin
