Yes, you read it coming from me - the idiot who practically worshipped Java because its easy structures and almost up for every task... "ALMOST"....
I found a tool called PalmOrb which allows me to use my PDA - Palm Tungsten T3 - as a matrix display for my computer while its in the cradle. Useless but cool - non?
Anyway, the guy maintining this piece of brilliance is dropping the project because he has so many real lcd's hooked up he no longer needs to (ab)use a pda for the task.
Ofcourse this code is written in C and ain't one of my strongest abilities (I kind hug the programming manual like a bible and hope for the best) so I decided to try to do this in Java.
1 hour later I got a working IDE for Java midlets set up, debugging and documentation in 4 browsers totalling over 60 tabs of information (yes - I manage to retreive stuff from all that).
Another hour later we've got a simple matrix renderer which uses a byte array to determine which character goes where and at 50+ fps for a quarter of the top of display it sounded promising - after optimising it could become even more so slower PDA's can render it as well.
Now all I need is a link to the PC.... Lets use the USB cable... no good - JSR-80 has been written but appearantly thats all there is - paperworks.
Well, lets use bluetooth! My PC has a dongle and it runs the serial port service - instant serial communication!.....
Unfortunately it appears that once again JSR-82 (thats the secret Langley CIA FBI shizzle name for fucking bluetooth) is a paper only implementation. After debugging it at my PC I uploaded to my phone to be greeted by a "ClassNotFound" exception - aka shit hitting the fan.
6 hours later I'm giving in - there is one company claiming to have a working Java bluetooth stack driver for PalmOS but guess what - you have to fucking buy it... along with 500 megs of SDK for lord-knows-what and actually.. I JUST NEED THE DRIVER.
So I'm giving in - Java on PalmOS 5 is worthless, besides the J9 IBM version you have the Sun version and both suck equally. Bluetooth on a T3 using Java ain't gonna happen - Tungsten sucks. Or rather Sun does as they appearantly don't rush development (last correction was years ago which means they had even more time to build the stuff).
If you used Google to search for clues on Bluetooth on Java using PalmOS - go home and start crying. If 9 hours of my misery ain't gonna deter you from trying - be my guest and if you succeed let me know, I'll drop my religion and start worshipping you instead :-)
