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?

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

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,

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

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>...

Installing MIDP in Palm Tungsten E?

Hi, where can I find information about installing the JVM for executing the MIDLets in a Tungsten E?
Thanks a lot.

download the midp for palm zip file from the sun site.
then go to this page ( http://www.pendragon-software.com/emulator.html#What%20is%20POSE )
and follow the instructions to perform a hotsync.
the hotsync on the emulator and the device are the same procedure.

Finding an MIDP file for Palm OS

Dear all,
I'm new to Java ME, and i'm very keen in developing a Java application for my Palm Treo device. I understand that I can download a MIDP for the palm device on Windows, particularly from the developers.sun.com site (the zip file is midp4palm-1_0.zip). However the sun hyperlink is a dead line (as the page is not found).
I tried doing google, but no luck.
Does anyone know any other website of which i can download this file?
Anyones help is much appreciated.
Kind regards,

{color:#000080}1. Report the dead link to Sun. I once had to do this, and within 24 hours I received an email informing me that the link had been restored.
2. Google midlet manager palm treo java midp download.

MIDP in Palm

Hi,
I'm development a software that will run in a Palm m-100. In this softwares the users must entering information during all the day and, in the end of the day, connect the Palm in the PC (using direct serial connect) and store the day's data in the PC.
But, I'm having a problem... The software is being development in MIDP, and now I have discovery that MIDP don't have serial communication (MIDP only has the HTTP implemented), then I have instaled the two JVM (KVM and MIDP) in Palm and two softwares are in development: one is the graphic user interface (development in MIDP) and other is the PC Coonector (using CLDC and KJava) to store the Palm data into PC using direct serial connect.
Is there any way to use direct serial connect in MIDP ? I don't want to use KJava for User Interface because it's very poor. If there's no way, then is there any way to call a KJava program from a MIDP program ?
Thanks in advance,
Sergio Stateri Jr

If you use MIDP, you have to use an HTTP connection to transfer data
from MIDP to your PC.
But you have the option of developing the PC Connector independent of MIDP
by:
a) Develop a Java conduit.
b) Use the Hotsync utility to backup data from RMS into your PC
and then write a program to read the backed up data and update the database.
You can see more details on www.palmos.com. Again, I am not completely
sure about above two options.

Writing Applications for Palm OS and Pocket PC

Hi All,
We are trying to architect mobile applications for both Windows CE (Pocket PC) and Palm OS which will access the local handheld database for storing and retrieving data. This local database will then be synchronized with the central database (via wireless or hotsync).
Is it possible to write a set of common java code (J2ME) and be able to do the above task ?
Thanks, Fazal

it is possible to run MIDP apps on both. OR, you could wait until the PDAP for Palms comes out, which has some similar AWT components as PersonalJava/Personal profile running on WinCE.

Personal Profile for Palm

is there Personal Profile for Palm? I try IBM J9, I cannot find it, where is it? or is it possible?

Why there is no Personal Profile for Palm, but there is, but there is no MIDP for Linux PDA, but there is in Palm. This is strange.

Jre 2.2 version compatable for Palm OS

Hi, I am using Palm os device. I would like to develop a application with SOAP and other facilities which is availabale on j2me 2.2 or 2.3 version but for Palm os there is only 1.0 version of J2me is available. Please tell me where from i get MIDP 2.2 or 2.3 for Palm OS .
Please send me mail on [email protected]

Is ther a player for any of the previous versions? i think
the only Palm-based device that had a player is the Sonly Clie. If
memory serves, it wasnt the OS itself, but the hardware power (or
lack thereof) on most Palm devices. Don't know where the FlashLite
player stands in relation to Palm devices though. You might want to
post on the mobile & devices forums or try to get in touch with
Bill Perry (www.flashdevices.net) at Adobe directly.
Good luck!

Kvm for palm os 4/5?

hi
is there any plan to support midp on palm os 4 or 5?
tks

If you have a Tungsten ARM device or a Treo 600, check out:
http://pluggedin.palmone.com/regac/pluggedin/Java.jsp
for a MIDP 2.0/ CLDC 1.1 VM.
Otherwise, for OS 4 you can use Sun's MIDP4Palm or IBM's J9 both of which are 68k VM's and support MIDP1.0/CLDC 1.0. Actually both these VM's work on the newer devices, they're just not optimized for them.

Java for Palm, Symbian, Pocket PC

I am kind of new to J2ME and just started playing around with it. I made a small midp app and it ran fine on the phone simulator. I have been searching for the past 2 days without any luck on creating an app that would work cross platform. The information I am finding is that for palm and Symbian they suggest C or C++ and would require writing an app twice. Then for the Pocket PC they suggest the compact framework. I guess I thought J2ME was supposed to be able to run on all of these with little code change. Am I wrong on this aspect? I am currently using Netbeans, would a different Java IDE make it so that I can create an app for all of these?

Normaly such devices only know MIDlets. This is becaus they do not have the power of a PC. In addition to that they are to different in hardware so an other API is to use.
I think it is notpossible to write a VM to do the same as a PC now.
Hope this will help you.

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.

Calendar Sync for Palm won't install Conduit

Hi, I'm trying to install Calendar Sync for Palm 10.1 on Windows 2K. Installation proceeds with no errors, but the conduit does not appear in the Hotsynch conduit list. It does remove the default conduits for Calendar, Date Book and To-Do. I've tried uninstalling Palm Desktop and Calendar synch, and reinstalling them, no luck. HotSynch works fine with the conduits that are left, and works with the default conduits if I don't install the Oracle Calendar Synch. I can't find any mention of this problems on the forum, does anyone have an idea of what could cause it?
Thanks.

There's a bug on the conduits as to were to find needed DLLs. It depends on setting itself in the path via environment variables.
The thing is that the conduits are not compatible with other Oracle client installations, which also add themselves to the path. An example is Oracle's Instant Client.
Check your system's path to see if you have any other Oracle client directories before CalSync's directory.
I had a TAR created for this and supposedly they will be 'patching' it for next version...
