J2ME on Windows Mobile 5.0 xda exec and series 60 nokia help!

Hi guys,
I am running an application on my Nokia 6680 mobile phone (symbian series 60), and I am able to recieve a bluetooth connection using a hard coded address of the bluetooth device. The bluetooth device I connect to is a GPS device, HOLOX BT-321. All working fine!
Problem occurs when I use the same application on an XDA Exec from O2 (also called i-mate Jasjar and M5000), the application does not connect to the bluetooth gps device, it pairs with it but when I run the application it doesnt communicate with the gps reciever, i.e the bluetooth light doesnt flash on the gps reciever to show a connection.
Why does it work on one and not the other? Both Nokia 6680 and XDA Exec uses bluetooth v1.2 as does the gps device. Both support J2ME and CLDC 1.1 with MIDP 2.0! So why doesnt it work? Any ideas??
The code i use is on the folowing website...

As I said you have to hard code the gps device your connecting to. It works on the Nokia 6680 fine!
Thanks...

Hiya,
did you find a solution to the problem?
I've actually tried to access the BT API from the Exec and it seemed that the KVM (Intent) had not implemented the Bluetooth API? interrogating the system.properties the bleuetooth specific ones all returned null
Also, when trying to scan for devices, the midlet would just hang.
The fact that it pairs, means actually little - I can access the GPS (and read the NMEA sentences) using C++ and native Windows calls (but no good from J2ME as JNI is not implemented)
if you have solved the problem, please do let me know ([email protected])
cheers
Marco.

J2ME on Windows Mobile 5.0 Pocket PC

I need to make a java application on a Windows Mobile 5.0 Pocket PC
It has around 200 Mb of memory I think. Am I correct that I should be using J2ME?
Which JVM should I use? I will need a graphical toolkit and whatever tools are needed to use JDBC.
How do I get the JVM onto the device?
Thanks in advance, any help would be much appreciated! I am very new to hand-held devices.

Well maybe it's not a Java ME CLDC/MIDP Thread. Depending on your PDA, you could use more than a subset of the J2SE API ... Furthermore, if you want to use JDBC, you can not use it on most Java ME phones because it's an optionnal API.
Here are some that could feet your needs (my favourite ones are first) :
* IBM's J9 VM
* Insignia's Jeode JVM
* Sun's Personal Java
* Mysaifu JVM
* NSICOM's CrEme JVM
* Access JV-Lite2 JVM

TS1363 I have run as many troubleshooting steps on Windows sees iPod but iTunes doesnt and it still wont help. Help!

I followed as many steps in this troubleshooting step as I could. I ran into some problems that my caveman brain does not understand and now I need some help. Here are some bumps in the road:
When I tried to verify the correct driver was installed (step 5), I ran into a problem when I chose the inf file: "the specified location does not contain information about your hardware" Waah! I tried to make sure I was updating the driver for the right device, because I watched verrrry closely what changed in Device manager (Win XP SP3) when I disconnected and connected.
I ran into another problem when I tried to run msconfig.
Is there anyone out there who can help me get iTunes to recognize the fact that my good old shuffle is connected???
Also, I have two shuffles and both are being given the cold shoulder by iTunes. BTW I did the complete uninstall and reinstall per the instructions...twice (I thought I had forgotten a step)

So is there any entry for these iPod Shuffles in Device Manager when you have them connected to your Windows XP Machine?

Windows Mobile issues re Flash Player

Hi - I am trying to install Windows Mobile on to my PC and it is proving a frustrating experience. Each time I try to load it states "You need Flash Player 8 or later. If you already have it this might be corrupt so please re-load" . I have tried installing FPlayer (v10) many times and am told that this has been successful, however I cannot progress past this same comment "You need..." i.e. cannot load the disk. I have searched this issue and it seems that there is a known issue regarding MS / Adobe Flash Player - something to do with 'permission' but I am unable to find anywhere that (i) explains this so that I can understand it (ii) suggests a solution in layman's terms (iii) has a link to a solution that works - they all say Error. I have tried re-booting, closing all apps before uninstalling old Flashj Player etc but no luck. Any suggestions much appreciated !

Hi Devin,
You would still need the (full) Flash 9 player on your mobile as that is the version of Flash that Xcelsius is generated for. Flash Lite will not work either because that is a cut down version of the flash player...
Maybe Adobe will create Adobe AIR for mobile devices (and support the Flash 9 player), we'll have to wait and see what happens...

Windows Mobile 5.0 and PEAP

We have successfully configured a group of 1200 series access points to use PEAP. I have installed a puplic Thawte certificate on ACS and configured group policy in Active Directory to issue certificate and set wireless settings. All of this works great with XP. I am now trying a Dell Axim running Windows Mobile. This handheld uses the Odyssey client and has all the required PEAP settings. This device works fine if configured with LEAP. I am getting an error on ACS "EAP-TLS or PEAP authentication failed during SSL handshake" .Since this handhelp and OS is not a domain member how does the machine authentication take place? I have tried creating AD accounts that match the device name, I have tried creating local ACS users that match the device name and nothing seems to matter. I am also not clear how the handheld knows how to deal with the certificate from ACS. I purposely purchased and installed a certificate from a well known CA so that the trusted Roots would be in the handheld so we would not need to deal with importing Root certificates from our internal CA. Also I should say we are running ACS version 3.3 and the latest 1200AP firmware.
Any help appreciated.
Thanks

Well an update on this issue. I am not able to get the PPC to connect with WPA and TKIP. It either get's and SSL handshake or fails machine authentication. The only way I can get this to work is to add a local account in ACS and supply the ACS username and password to get it to authenticate.
I realize that the PPC or Windows mobile device cannot be a domain member therfor mapping to a machine name in Active Directory would be a challenge. Is there any way to get these devices to access a domain username and password? I have tried creating dummy domain account for the machine name but it does not seem to matter. I have also tried creating a dummy machine account in ACS but that does not work either. Does anybody have PPC or Windows Mobile devices authenticating using ACS and Active directory? Any help appreciated.

Does LV 7.0 PDA module support Microsoft Windows Mobile 2003 software for PocketPC?

I am evaluating the possible use of PDA
that runs Microsoft Windows Mobile 2003 software
for PocketPC and would like to know if the
LabVIEW 7.0 PDA module supports this software.
I am planning to scan barcodes with this PDA
and transmit this data over a WLAN to database.
Thanks!

Depending on the Pocket PC PDA type it is practical to add a barcode reader attachment and then use this as keyboard input into the PDA. You can look at a Grabba barcode Reader attachment (www.grabba.com)
I work for Grabba in R&D and we are looking at demand in this area (which is why I was looking at the forum to try and determine whether a need exists).
If we can help you let us know. I would be interested in knowing where you think this will help you. We have our own ideas but input from the field is most welcome.
cheers

Error while trying to debug on windows mobile 6.1 with j2me SDK 3.0 ea

Hi,
I tried to debug a simple application today. It works fine with the emulator but debug fails to connect to the device.
I followed the steps described in the userguide of 3.0.
host operating system: windows xp sp3
device: htc touch pro
device operatiing system: windows mobile 6.1 professional
The device is listed in the device selector of the SDK as Touch_Pro
The device is connected and active sync is running (i can explore the phone using windows explorer)
sun-java-cldc-emu.cab has been installed on the device and is running
When i try to debug the application from the SDK or netbeans 6.5(added 3.0ea as a platform) i get the following error:
Starting emulator with port number 51307
Cannot create device connection: Failed to connect to device 9!
Result: 1
I tried setting the loglevel to DEBUG in log4j config of the SDK, but thats it.
Are there any other settings i can change to get more detailed output?
Where do you report bugs/feedback for j2me SDK 3.0 ea?
regards,
dominikg

-- added more specific questions

Hi dominikg,
At first, You can try to restart the device-manager from system tray.
If it doesn't help, then try the following:
- stop the device manager
- Remove c:\Docement and Settings\<your User>\javame-sdk folder.
- Ran the device manager from <SDK>/bin directory
- try to debug again.
Did you tried to change port 51307 to another.
Early access build had some problems with device manager, I hope that final release will be better :)

J2me cldc midlet for windows mobile(cdc) in netbeans

Hi,
I have a midlet developed in Mobility Pack 5.0, and I have to change it so, that it works, and looks ok on Windows Mobile. That means that I have to port a cldc midlet to a cdc device. I've found two vm-s for windows mobile, for running midlets. J9, and CrEme. I also saw that the mobility pack for cdc together with CrEme make it possible to build CDC apps for windows mobile. The question is, how can I integrate the cdc windows mobile emulator with the mobility pack (for CLDC?), to be able to develop midlets for Pocket PC?
Thanks!

I think you go to Tools Menu -> Java Platform
and add a new platform by chose j2me platform.
Then the netbeans search for the emulator and add it in the IDE support.

Impossible to send SMS through J2ME with a HTC which OS is Windows Mobile

Hello,
I've developed a J2ME application with possibilty to send a SMS.
This works fine on some mobiles like Nokia 6300, but doesn't work on a HTC equipped with Windows Mobile.
Precisely, in the case of my HTC, the variable supportedSms below is allways null.
Can someone tell me how to solve this matter please?
            String supportedSms = System.getProperty("wireless.messaging.sms.smsc");
            if(supportedSms == null){
                    //this means the mobile can't send a sms through j2me code
            }else{
                    //this means the mobile can send a sms through j2me code
            }Regards

Sorry, for digging up this topic, but has anybody found a solution to the problem? My sms sending application seems to work on SE's, Nokias, Motorolas etc. but not on Windows Mobile. I am testing it on a HTC s710 with Windows Mobile v. 6.0.

How to Run a Hello World Java application on WIndows Mobile

Hi!
We have a sample Plug-in environment Java application downloaded from http://www-128.ibm.com/developerworks/library/os-ecl-ercp/index.html - IBM library.
We have downloaded the source files org.eclipse.testworkbenchapp_1.0.0.jar and tried running the application on desktop PC, this worked fine.
We are using Eclipse 3.2 to run this Java application on Desktop.
Now, we are trying to run the same application on Intermec Windows Mobile 5.0 device.
1. The device has IBM J9 ? WebSphere MicroEnvironment MIDP 2.0 for Windows Mobile2003 installed in it.
2. On installing this on Windows Mobile, in Start ? Programs ? we find MIDlet HQ - on launching this, opens a window with Install button.
3. On Click on Install button, another window opens which asks for URL to install.
4. In the URL Edit box, I give file:////Org.Eclipse.testWorkbenchapp.feature_1.0.0.jar which is present in \MyDocuments\Update site folder copied from desktop workspace via Active sync ? As mentioned in the above IBM library site.
5. I have also tried file:////MyDocuments\Updatesite\Org.Eclipse.testWorkbenchapp.feature_1.0.0.jar as input to URL.
6. On click OK, I get an error titled AMS Error with description The application descriptor was missing the required MIDlet Name field.
I am held up here and not able to move further.
As mentioned in the above IBM library site I tried downloading the update site folder via Eclipse ? Software Updates ? Find and Install in Help menu.
I selected Search for new features to install and browsed the Update site folder location present in my Eclipse workspace. This also does not work.
Any help in this regard in greatly appreciated. Thanks in advance!

I would ask such questions in the J2ME forums, or even better in a websphere forum, like here:

How to install the JRE that comes with JME 3.0 to a Windows Mobile device

From Sun's JME download page:
Integration with 3rd party emulators and Windows Mobile devices
The new Java ME Platform SDK architecture allows integration of 3rd party emulators and devices. Java ME Platform SDK comes with Sun's Java runtime environment for Windows Mobile. A user can install this runtime on a Windows Mobile device or a Microsoft device emulator and experience all the on-device features of Java ME Platform SDK.*
My question is, how can I install the Java runtime environment that comes with Java ME Platform SDK 3.0 to a Windows Mobile device. I am a newbie in this device programming and I'm setting up my development environment. So far, I have installed JME in my computer, and have also installed both the Windows Mobile 5 and Windows Mobile 6 emulator. I've been searching the internet for answers, but it always points me to using a third party java runtime such us Mysaifu, etc. I would like to stick with what is packaged with JME if possible.
If anybody assist me or direct me to an online documentation on how to do this. All help is greatly appreciated :-)

I had some success installing on a real Mobile 5 device [http://forums.sun.com/thread.jspa?threadID=5344195]
There is a link to a doc on the main download page, item 5 under How to Install. [http://java.sun.com/javame/downloads/sdk30ea.jsp] I used this for the real device, Treo 700w. Did not try it with an emulator.
The support looks to be an emulator rather than a JVM per say. But then again I could be wrong on that. I too had poked around looking for a JVM, CrEme, J9, etc..
I do have a commercial app installed on the Treo that uses IBM's J9, which is seems requires a contact with a sales person to get ahold of. I had hoped to find something that might clue me in on how to "hook up" my own J2ME app with the J9 installed by the commercial package. But I've pretty much decided to get a real J2ME handset rather than continue to waste my time hacking up something with WM. Now the question is which one makes a good reference platform?
