CommConnection on MIDP for PalmOS v1.0 ?

I use the current build enviroment: j2sdk1.4.2_05, J2MEWTK 2.2 beta and midp4palm1.0 for Plam platform.
I try to use CommConnection method for open Serial port.
Trying to discover available ports:
System.getProperty("microedition.commports");
On the buildin WTK emulator it's return: 0,1
Palm V and m105 devices have Serial port, but they return: null
In the http://developers.sun.com/techtopics/mobility/midp/articles/genericframework/
CommConnection declared as MIDP 2.0. Support is optional.
Also on Palm V and m105 following code:
try { CommConnection cc = (CommConnection) Connector.open("comm:com0"); } ...
raise Error:
'Unable to load class javax/microedition/io/CommConnection'
Can someone answer: is CommConnection implemented on MIDP for PalmOS v1.0 ?
Are there any J2me's for Palm which implement CommConnection ?

Yes, IBM's MIDP 2.0 for PalmOS Tungsten devices supports the CommConnection. Allows serial port, IRCOMM, Bluetooth serial. Best run on larger heap devices such as Tungsten "C", T3, Zire 72, or Treo 600.
The latest release (http://www-306.ibm.com/software/wireless/weme/) also has an Eclipse Web update that extends the support to include JSR-075 FileConnection and PIM.

Application memory on CLDC/MIDP for PalmOS

Hello,
I've got serious problem running my MIDlet on PalmOS. It seems, that the maximum amount of memory I can assign to an application is 64kB. It doesn't matter how much memory Palm (or POSE) has, I cannot increase application memory in JavaHQ. Is there any possibility to change it. I do need more memory!
Thanks for your help,

Thanks,
I have one more question. When my application (MIDlet) is starting, it creates many classes (arrays, Vectors,...) which are not not used afterwards. I think, the garbage collection should take care of disposing them, but it seems like they are not disposed and this is from my memory problems came from. I tried using "System.gc()", but it didn't help.
Could You tell me somethig about "gc", does it work at all or what should I do to make it working. I tried to trace it, but when I check STDOUT.txt (for testing I'm using POSE) the amount of garbage collected bytes is 0 :(
Thanks in advance

MIDP for Palm OS

I'm getting a bit confused between the cldc + palm overlay (com.sun.kjava) and the new hype regarding MIDP for Palm OS. Is com.sun.kjava going away, or is it another tool for another purpose?

Any ideas on implementing pdb-like functionality?Hi c2cate:
Sun has modified the com.sun.kjava classes. The most recent j2me_cldc installation includes updates to the com.kjava.api package. I'm using this package and will continue to do so. It's in my development environment and will stay there until I remove. Therefore, does it really matter if and when Sun choses to stop supporting/modifing the com.sun.kjava at some later date?
I've written a server-side API that extracts data from mainframe-databases and server-databases and creates PDB formatted files which are then installed onto the Palm. I've used the com.sun.kjava widgets to develop a Customer Relationship Management application that contains over 20 screens and accesses (7) different PDBs. I've also enhanced the Palm Spotlet to now allow the users to access data from the PDB or to request and receive data via a wireless connection with strong-encryption which also updates the respective PDB record.
P.S. Mr. Bill Joy , I'm more concerned with the following:
- I can create PDBs externally and install them onto a Palm, initializing the Palm with data.
- PDB data is accessable by other Spotlets and applications.
- I can HotSync the modified PDBs back to the server-side and mainframe-side databases.
- Can I create RMSs externally and install them onto a Palm or Cell phone?
- Why is RMS data accessable only by those Midlets contained in the suite.
- Can I HotSync the modified RMSs back to the server-side and mainframe-side databases.
- Can the RMS classes read PDBs?

Is MIDP for plam fully support the Palm OS 4.0 ??

I am currently doing the research on develop the application using MIDP for Palm.
I decide to buy the m500 which running on Palm OS4.0. May I know whether the Palm OS 4.0 support and fully tested on MIDP application ?
In my design, the PDA will link to the web server by using the Ethernet cradle to exchange the information. This is the way that i think it is efficient to send the HTTP request. Is it possible using the serial cable to send the http request thru the desktop? pls suggest other method.
Thank in advance ...

Is the MIDP run slow on the Palm OS 3.5 emulator???
izzit faster when running on the device??? Yep, midelts on real device run faser.
How much faster? hard to say, it depends on application
and your PC.
I have noticed that my midlets run about 7-10 times
faster on PDA than in emulator running on PIII-1GHz-256MBRam
and i always get and pop-up error about
memory while running on the emulator for any midp
sample program.Yep. Same here. POSE shows errors, when midlet uses some
of gui classes (Gauge).However, on real device never had
those errors.
I have tried different ROM mages, but no luck.
So far, I just press <continue>...

Infrared / Serial ports access in MIDP for Palm

Hello,
Do you guys know if MIDP for Palm allows to connect to the IR / Serial ports ? If yes, any examples ?
Thanks,
Vadim.

I'm very interested by your discussion, i have searched a lot of information about midp and the access to the serial port.
The specifications of midp says that the comm protocol is not available in midp.
The IBM J9 Java VM is supposed to be full midp implementation but only only for x86 processors. The lcdui package is not available with the J9 VM for palm. The lasts contact i have with ibm about this subject, they said that they will implement lcdui but they can't say when .... perhaps in 2002.
I don't know any other Java VM witch have a full midp implementation ... Kada VM will be but i don't know when ...
If you have any other information, i'm very interested
Thanks by advance

MIDP for Palm on OS 4.0?

Hi,
The ea version of the palm midp says it is for Palm OS 3.5. Has anyone tried this with OS 4.0? (such as the Sony Clie 610?)
Thanks!

[robycox],
The current MDIP APIs is not officially tested on the the release of Palm OS i.e. v4.0.
Other 3rd party companies have released their very own CLDC compliant kVM for the Palm OS e.g. Jbed Micro Edition CLDC[tm] from Esmertec:
http://www.esmertec.com/p_jbed_cldc_long.html
The requirements for the kVM by Esmertec states Palm OS 3.3 or above, so their VM might work on the PalmOS 4.0

Personal Java For PalmOS

Is there a Java VM for the Palm OS and how do I get it. I would like a free one if possible.

Currently, there is no Personal Java VM for the PalmOS. The present Palm hardware doesn't meet the PJ spec minimum requirements. The MIDP4Palm download is a J2ME/CLDC implementation which allows you to build MIDP applications.
The new Palm Tungsten series includes a new, faster processor, but current configurations lack sufficient memory to implement a full PJ spec. The upcoming PDA profile will most likely also support MIDP applications and will, presumably, have implementations on both Palm and PocketPC PDAs. (maybe even Linux based pdas as well.)
There are no reported plans for a PalmOS, Personal Java or the succeeding "J2ME/CDC/Personal Profile" implementation in the future.
If you need to develop for the PalmOS, MIDP is your best choice right now. If you need to develop in Personal Java, go with PocketPC, if you can get a Personal Java VM for it...

Flash for PalmOS

Iv seen some older posts on this but they are all a while old
so i thought id ask again, is there a version of flash player that
works on palm os or through j2me? Or is anyone working on creating
one or know if flash will release one seing the popularity of
things like the treo which has web access anywhere?

If Adobe doesn't offer it then it is not available. You'll
have to contact
Adobe.

Installer for AdobeReader for PalmOS does not work

I've downloaded both AdobeReader305-PalmOS.exe and AdobeReader305-PalmOS_esp.exe.
None of them work. The initial installer opens (the one that unpacks the real installer), but then, the window is closed and nothing happens: the task bar shows nothing, the InstallShield NEVER opens, the "Acrobat Reader for Palm OS" splash never appears, etc.
On the task manager we can see the "AdobeReader305-PalmOS.exe" and a "Setup.exe" running and that stuck right there, without using processor. I left those for 2 hours and nothing happened.
I've tried all the next "workarounds" but NONE of them worked:
* I have deleted all my temp files from my %TEMP% and %WINDIR%\Temp folders. Didn't work...
* I have opened Windows holding both shift keys on startup, so less apps would be initially opened. Didn't work...
* I started Windows in Safe Mode; the InstallShild installer OPENED (the "Acrobat Reader" splash opened), but in the middle of installation, some errors appeared (with no description). Finally, the desktop application was installed, however the app does not recognize my Treo 650:
- It asks me to hotsync then click "OK", but after I hotsync the "OK" button never gets enabled
- If I add a file to transfer to the Palm, then hotsync, the file is never sent to the Palm (it stays on the list).
Is there a way to fix this? I don't know, fixing the InstallShield, manually installing everything, etc.
Thanks

WARNING: Do not install this file. It is damaged and will corrupt hotsync so that you'll not be able to hotsync again. This happened to me. I solved the problem by doing a hard reset + clean uninstall of Palm Deskop on my PC (see: http://h30434.www3.hp.com/t5/Palm-OS-WinMo-Hardware-and-Software/Instructions-for-a-quot-c lean-uninstall-quot-of-Palm-Desktop/td-p/2287099). I'm not sure if the hard reset was nessesary though.

J2ME for PalmOS and WinCE? GPRS?

Hi all,
I'm a Java developer for a couple of years, but I really know nothing about J2ME (or JME).
As a J2ME newbie I'd like to know if there's support for J2ME on PalmOS and Windows CE (Pocket PC). Could somebody point me some resource describing the supported plataforms?
Is it straightforward to do network communication using GPRS? Is it even possible?
Thank you!

Best Sync software for PalmOS to Mac OS X

I am about to buy a second mac and send my PC to the bone yard. One thing I need to be able to do is synch my Treo 755p (PalmOS) with the Mac. Right now I use Outlook for Calendar, Contacts, Memos and Tasks.
I would prefer to not use Entourage and use the Mac OS calendar and contacts instead since I have a .Mac account and will soon be able to sync with the cloud.
I read that iSync isn't great. I also hear conflicting reports on Missing Sync, but most of the posts are older versions. Does anybody have any recent experience with Missing Sync or other that they can share? Thanks.

I've been using Missing Sync since I won a copy as a door prize about 4 years ago and I've bought 2 upgrades since. I've been very satisfied with the software and on the few times where I've had issues or problems I've gotten prompt and helpful answers from the company.

EMERGENCY: Mirror for CW for PalmOS 9.2/9.3 updates ?

Hello!
I recently found out that Freescale is not hosting the 9.2 & 9.3 updates of Codewarrior for Palm OS 9 (Windows) anymore. Understandable, since it's now a defunct product. However, my company is still using it (don't ask), and we're now changing our PCs.
Do you know of any place these updates (9.2 is 84MB IIRC, 9.3 is rather small) are mirrored? And, if you don't, would you care to help me by actually mirroring them somewhere?
I would really appreciate your help with this.
(My apologies if you find more posts like these from me in other forums. To be honest, the more people finding about it and mirroring the updates, the better for us all.)

Bug in List-representation at MIDP for PALM?

Hi There,
in my MIDlet on a Palm I've got a screen with a list. The size of the list is dynamic, I can add and delete items on it. When I have more items on the list than the display can show, there are two arrows (up and down-arrows) on the screen, with whose I can scroll down (or up).
Now there is one error: if the list fits just perfect into the screen, the arrows appear ... ok, that is not very bad - but if I push the down-button, the whole system crashes and I have to make a soft-reset ... this error does not appear on the same MIDlet running on Pocket PC or Symbian OS ... can someone tell me how to avoid it?
I am using a Handspring Visor with Palm OS 3.5.2H2.0
Thanks,
Jens

Can show your code?
If don't. Try to place this code in a Class as static method.

Https with midp and servlets

Hi Everyone,
I've written an application in MIDP which connects to a servlet and the servlet returns some information using a HTTP connection. Now I want to build in some sort of security and heard that it is possible to use HTTPS. Does anyone know some links where there is a tutorial or explanation on how to use HTTPS (both in MIDP as in J2EE)?
Thanks in advance,
Martijn

it doesn't exist in MIDP for PalmOS yet. apparently it's due some time in "the next couple of months" (read sometime in 2010).
As for the other midp implementations, who knows.
