2 Installing and Running Applications on the Intel Galileo Gen2 Board

There are several ways to use the Oracle Java ME Embedded platform on the Intel Galileo Gen2 board.

• Directly run commands using a command-line shell interface or logging in using the ssh protocol.

• Manually start a Developer Agent program on the desktop host and run commands using the Application Management System (AMS).

• Run NetBeans IDE.

The following is a typical example of using the commands to install, list, run, and remove an Oracle Java ME Embedded application on the Intel Galileo Gen2 Pi board. Most commands can be terminated with the Ctrl-C key combination if they become unresponsive.

First, install the application using the installMidlet.sh command, specifying its location on the local file system.

root@galileo:~/bin# ./installMidlet.sh /home/root/EmbeddedTestProject.jar
Java is starting. Press Ctrl+C to exit
The suite was successfully installed, ID: 2

After an IMlet is installed, note its ID: in this case, it is 2. Next, verify it using the listMidlets.sh command.

root@galileo:~/bin#  $ ./listMidlets.sh 
Java is starting. Press Ctrl-C to exit
detect_fb_type: unknown device type
Suite: 2
  Name: EmbeddedTestProject
  Version: 1.0
  Vendor: Vendor
  MIDlets:
    MIDlet: GPIODemo

You can run any installed IMlet using the runSuite.sh command. This command runs the IMlet that was just installed, passing any logging information to the standard output of this command. Note that you can press the Ctrl-C key to exit from this command, which will terminate the application.

root@galileo:~/bin# ./runSuite.sh 2 
Java is starting. Press Ctrl-C to exit
Starting - GPIODemo

You can use the removeMidlet.sh command to remove any installed IMlet.

root@galileo:~/bin# ./removeMidlet.sh 2
Java is starting. Press Ctrl-C to exit
Suite removed
root@galileo:~/bin# 

You can verify the results by using the listMidlets.sh command.

root@galileo:~/bin# ./listMidlets.sh 
Java is starting. Press Ctrl-C to exit
No suites installed

The Developer Agent program runs on the Windows or Linux desktop and transmits all communication to and from the Oracle Java ME Embedded executable file on the Intel Galileo Gen2 board.

You can start the Developer Agent program on the desktop host computer either in a server or a client mode. The server mode is used by default. The client mode must be configured in the jwc_properties.ini file.

1. Extract files from the copy of the Oracle Java ME Embedded ZIP archive on the host desktop.
2. Delete the /appdb and /bin directories.

1. Change to the bin directory on the Intel Galileo Gen2 board and run the ./fix_permission.sh command:

   root@galileo:~/bin# ./fix_permission.sh
   

2. Run the ./usertest.sh command

   root@galileo:~/bin# ./usertest.sh
   

3. Change to the util directory on your desktop host and enter the following command.

   C:\mydir\util> java -jar proxy.jar -socket <RPI IP ADDRESS>
   

   You should see an output similar to the following:

   Trying to open socket connection with device: <IP Address>:2201
   Connected to the socket Socket[addr=/<IP address>, port=2201, localport=54784]
   Open channel 8 with hash 0x390df07e
   notifyResponse AVAILABLE_RESPONSE on channel 8
   Channel 8 CLOSED -> AVAILABLE
   Open channel 9 with hash 0x0
   

1. Run the usertest.sh command in the /bin directory:

   root@galileo:~/bin# ./usertest.sh
   

2. Change to the util directory on your desktop host and enter the following command.

   C:\mydir\util> java -jar proxy.jar
   

   You should see an output similar to the following:

   Starting with default parameters: -ServerSocketPort 2200 -jdbport 2801
   Channel 8 CLOSED -> AVAILABLE
   Waiting for device connections on port 2200
   

To run IMlets on the Intel Galileo Gen2 board using the AMS CLI, you must first make a raw connection to the AMS CLI and then use commands.
