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,

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.

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.

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?

How to display an image using MIDP on Palm?

How can I display an image using MIDP on Palm? The following code works on the Siemens SL45i, but not on Palm:
public class Test extends List
Image image = Image.createImage("/images/test.png");
append("item 1", image);

Have found the exact same problem when trying to display an image (other then the default (null)) in a list, on a Palm.
The image displays correctly on a form, but when set on an element in the list, it does not display. (mind you this is in both emulator mode and on the real device)
It does not seem to be related to size of the image.
The Sun documetation states, that you should not rely on it been displayed (obviously it's an implementation issue with the Palm, and other devices I have not tried)
But like to hear definitively from Sun though!

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,
Jens

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>...

Midp - palm.... HELP!

Got real excited last week about making some apps for my palm, so I started gathering the resources needed for developing. J2SE... J2ME... midp for palm (including jad jar prc converter)_
spent the last 3 days looking for this file.... midp4palm.zip
Seems that Sun is the only point of distribution for this file... ok, thats reasonable. The market I develop for would just go to Sun site for dl no problem.
Every last link found to this is broken...
J2ME downloads.... midp -> download : broken!
java.sun.com/products/midp4palm/index.html : broken!
Palm site : can no longer distribute message
ok, maybe in a few days I can find some russian ftp server temp directory someone forgot to delete and get it there, but what about the market I develop for? What would they do to install midp on their palm devices?
being new to java development, this is frustrating and alarming.
thanks for letting me vent...

Circumvention prevails!
MIDP PRC for palm :
http://freewarepalm.com/utilities/midpforpalmos.shtml
JAD/JAR ---> PRC converter tool :

Now, if the rest of the world can find this post, maybe they can get some use out of my apps for.

Problem: List images / Palm / Forte

Are there any issues with creating JAR files that contain PNG files with Forte?
I cannot seem to get images to display in a List on a Palm. With the Forte debugger, I am able to see that the Image is found. No exceptions are throw when I try to get a handle on the PNG.
When it comes to displaying the image, the default list icon is displayed instead.
My image is a black and white, 10x10 PNG image. It is 1kb in size.
Has anyone experienced this problem? If so, how did you solve it?

[kevinsikora],
Not that I know of. With the MIDP 1.0 for PalmOS, there is a restriction of the maximum image file size of 64 kbytes for a PNG image file.
Can you check the Preferences settings on the "Java HQ" AMS application? There is a setting for the color for the MIDP for Palm OS 1.0 environment, that should state black and white since your PNG image is black and white.
Can I assume that you are using the Image.createImage() method in your code and that the PNG file is placed correctly in the JAR file?

J2ME, MIDP,CLDC, ...

Hi all,
i'm new to this "micro Java tech" and i would like to have clear some general concepts ;-)
right now i've got an application written in "waba" for running it in a Palm device, i just needed waba VM, waba classes and some applications for creating the prc files.
Now i would like to "translate" and walk into the sun philosophy...
i've been reading around and i've found KVM what is quite clear, and then J2ME, MIDP and CLDC... do i need all this for writting my java application and running it in a Palm device?
Which is the minimal set for doing it?
Which API is the correct one for what i want CLDC API or Java2ME API?
my messy brains would thank any help....
thanks,
Laura.

hi, if you want to develop and run your apps on Palm devices, I think what you need are J2ME Wireless ToolKit and MIDP for Palm from Sun Microsystems. These tools can help you.

Hot Sycn. in Palm

I am writing palm application using j2me CLDC midlet. The application requires persistent storage of data, which I use RMS api to handle. However, the application also requires hot sycn. of data between palm and desktop PC.
Does j2me CLDC midlet have ways yo handle hot sycn. mechanism or there is another way round.

i'm doing the same thing as u do. all u have to do for the sync part is to make connection between your pda and pc. however, the api of midp for palm does not provide such function. u have to use other application to help u make this connection. for further detail, u may go to the following site to have a look.
1. come.to/SyncBuilder
2. http://www.mochasoft.dk/palm.html#palmppp
but these 2 programmes only support com port. if your cradle uses usb port to connection pc, u'll have to find other ways.
if u can find ways to connect your pda and pc through usb, pls email and notify me. thanx.
my email is [email protected]

Exclusive choice list with Palm OS Emulator

hi,
I try to use an exclusive choice list with a palm os 3.5 and 4.0. (MIDP for Palm 1.0.3)
But my screen show me only the text with a small point in front of it. It isn't possible to determine visually which line is selected!
I haven't find any information about this problem in bug list and I'm very surprised!
Is that a solution?
Thanks
Pascal

[rapazp],
Firstly, I do know that the MIDP for Palm OS 1.0 BETA has not been officially tested on PalmOS 4.0, so you may get some funny rendering issues with the screen. However, you should not get any problems with PalmOS 3.5.
An "Exclusive Choice" List is usually rendered to the screen as a group of radio buttons so you should get to see a couple of radio buttons that you can scroll up or down and pick one choice. Are you testing this on the emulator or are you testing this with the MIDP.prc installed on your Palm device?
Below is some simple source code sniplets using Exclusive Choice List:
List list = new List("Border Style", Choice.EXCLUSIVE);
list.append("Selection 1", null);
list.append("Selection 2", null);
list.append("Selection 3", null);
list.addCommand(BackButtonPressed);
list.addCommand(OKButtonPressed);
public void commandAction(Command cmd, Displayable d) {
if (cmd == OKButtonPressed) { int i = (List)d.getSelectedIndex();}
else if (cmd == BackButtonPressed) { //code to handle the Back button command}
}HTH.

Is this possible (J2ME & Palm)?

Using J2ME and Palm os emulator to simulate using a palm pilot to access web pages on my own server? What tools are out there for me to use? Do you know of any tutorials that may help me do this?
Thank you for your reply.
Luu

I think you should be using the CLCD configuration and the MID Profile (there is and implementation of MIDP for Palm OS that will help you develope java applications for java).I never tried but I know that it's possible to make a MIDlet (a java application that uses MIDP) that interacts with servlets and jsp.

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.
