The JavaMO is a lightweight Mobile Orbiter client. It receives rendered pictures from the Bluetooth dongle Orbiter and sends keystrokes and pointer events back. The protocol used over Bluetooth is BD.
JavaMO has full support for local/in-house use when connected to a MD , but has limited support for out-of-house mode, when it connects via the Internet. For instance, because of a limitation of Java, it cannot intercept phone calls from LMCE like the Symbian orbiter can.
JavaMO is included in 810.
When your phone is detected, LMCE will ask what type of phone it is. Select "Generic Java phone". The JavaMO should be transferred to your phone, and you have to accept it on the phone when asked about receiving files. If this fails, you need to download the application from the website mentioned above.
Screen Size, UI Variant
There is no automatic screen size detection of the phone yet, so you also need to perform these steps to get the best setup for your phone. Go to the Orbiter in the pluto-admin web interface (select Orbiters in the Wizard on the left) Adapt the PK_UI, PK_Size and resolution values to match your phones display. If you have no touchscreen on the phone stick with symbian for PK_UI, otherwise choose the normal variant.
To check if your phone is compatible, you might want look in the device list of J2MEPolish. Just click on the JSR-082 bluetooth capability and click search.
The JavaMO detectes the phone model and uses key mappings defined for that model. This maps available keys on the phone to the keys LMCE expects.
You can hide the orbiter by holding the end call key, this will take you to the JavaMO menu. Handy if you want to view the log or exit the application.
Custom key mappings
Phone key - LMCE key Volume down - End call Volume up - Phone pencil Joystick select - Enter
The Nokia E61 has a full keyboard. To select the numbers you have to hold down the blue function key, and press the number together with it.
For most phones you need the jad and the jar file. Copy both to the phone and select the jad from the file or application manager.
You have to exchange the libBDCommon.so with the provided one on all 0710 cores or MD's with a Bluetooth_Dongle. Download the replacement libBDCommon.so from http://vt100.at/javamo/ . In /usr/pluto/lib rename libBDCommon.so to libBDCommon.so.old, then copy the new version you downloaded into this directory and reboot.
LMCE 710 Plug and Play detection
When LMCE asks you for the type of phone select "Symbian S60". The application push will fail. Thats ok. Just answer no to the question if LMCE should resend it.

JavaMO development guide
Haris initial alpha version can be found on http://vt100.at/javamo/. A beta version can be found at sambucas site.
Checkout the source from the svn tree:
svn co http://svn.linuxmce.org/svn/people/hari/javamo/ cd javamo
First we install the Java SDK. I used version 6 update 6. Download it from the sun download center: http://java.sun.com/javase/downloads/index.jsp
chmod +x ./jdk-6u6-linux-i586.bin ./jdk-6u6-linux-i586.bin
That gives us the directory "jdk1.6.0_06".
Now install the wireless toolkit version 2.5.2: http://java.sun.com/products/sjwtoolkit/download.html
Specify the _full_ path to the "jdk1.6.0_06/bin" directory (this example assumes javamo was checked out to "/home/hari/src/javamo"):
Enter a path to the Java 2 SDK: /home/hari/src/javamo/jdk1.6.0_06/bin
After the installation you should have the following subdirectories in the javamo directory:
Building the application
just run "make":
You will find the "JavaMO.jad" and "JavaMO.jar" file in the "output" directory if the compile succeeds.
Install the application on the phone
That strongly depends on the type of phone and sometimes your mobile carrier.
Nokia Symbian devices
For Nokia Symbian Series with a memory card you can use the "install" target in the "Makefile". Just adapt the Bluetooth address of the phone in the "Makefile" and run:
Then go to the file browser on the phone, switch to the memory card and select the "JavaMO.jad" file. Make sure you have enabled the installation of unsigned applications in the application manager.
Developers in the United States
If you are developing in the United States, the process to install JavaMO on your phone depends heavily on the operator you have for your mobile.
If you have a Sprint or Nextel phone, you can install the MIDlet over the air using | Sprint ADP's OTA content uploader.
On a Nextel phone, you can also install it using a cable downloading the iDEN Java Application Loader. There are mechanisms for cable-loading an application onto a variety of Sprint CDMA phones, but these vary greatly in their reliability/ease of access.
If you are working with a Verizon phone, you will need to have a BREW developer license and toolkit to load an application onto the device. Chances are you don't have this.
If you are working with an AT&T or T-Mobile GSM phone, you should put the JAD and JAR files in a publicly accessible web server, then point the web browser of your phone to the JAD file -- it should begin the download automatically.
Building the documentation
Direct your browser to the file "doc/index.html"
On device debugging with a Nokia N and E series phone and Linux
To get the output from the application running on the phone on a computer screen, do the following:
- Register with Nokia and get the Symbian SDK
- Transfer the "EcmtAgent_MIDP.SIS" application on the phone and run it, uses bluetooth per default
- Go to system - application manager on the phone and install the "RedMIDlet.jar" (shows "not installed")
- Go to the application folder and run the "Sdt.out.redir" application
- do a "sdptool browse" on your notebook with a supported bluetooth dongle (hci device must be up) to find out the rfcomm port. You should see something like this:
Service Name: EcmtAgent Service Description: Bluetooth bearer for EcmtAgent Service RecHandle: 0x10043 Service Class ID List: "Serial Port" (0x1101) Protocol Descriptor List: "L2CAP" (0x0100) PSM: 3 "RFCOMM" (0x0003) Channel: 3 Language Base Attr List: code_ISO639: 0x656e encoding: 0x6a base_offset: 0x100
- run a command like the following after substitution of the Bluetooth address and the rfcomm channel:
while $a; do rfcomm release /dev/rfcomm0 ; rfcomm bind /dev/rfcomm0 00:17:C4:C3:36:24 3 ; cat /dev/rfcomm0 ; done
Example output (process list, system info and the javamo console output):
