![]() ![]() If you want, you can run it locally too, just by selecting the default configuration file (Run, Set Project Configuration). You just need to provide the IP address, username, password and the JRE/JDK path of the Pi (on the LAN, with SSH enabled).Īfter that, simply go to Properties->Run, select the Remote platform, and add a configuration file (providing a name for it), and you’ll be able to run your project on the Pi. The server is embedded in a Lego case to hold a Pi camera, and the third one has an XBee antenna to wirelessly connect to the Arduino on the right.Įxcept for the server, for the other two SE projects, the new capability of NetBeans IDE 8.0 beta that allows you to select a Remote Java Standard Edition platform comes in really handy, as it greatly simplifies the process of deployment and debugging on the Pis. ![]() The second is my own setup, with the three Raspberry Pis on my table, just when I’m deploying a JavaFX client from my laptop to the Pi on the left, which is connected to the monitor. The first one is the backend in Mark’s shed, where all the sensors are powered with renewable energy coming from a small wind turbine and three small solar panels. In the client, the user can see values in real time, charts with data for a selected period of time, or command the devices. In the backend, the Pi gathers readings from several sensors installed via serial port and also controls a few connected devices. The communications between the three of them is done via WebSocket. Pi “Client”, the client, with a JavaFX (SE) project Pi “Master”, the server, with GlassFish 4.0 (Web Profile). Pi “Remote”, in the backend, with a Java SE project We use three different Raspberry Pis for three different tasks: Where request and response are new values of the properties proxy.udp_device_detection_request_port and proxy.udp_device_detection_response_port.In preparation for the talk G-Force! Self-Powering Global Sensor Nets for IoT that Mark Heckler ( ) and I will give in a few days in the IoT track of JFokus 2014, we’ve been using the brand new beta version of NetBeans IDE 8 to deploy, debug, and run two of the three different projects required. To modify the values of these properties, create the proxyOptions.txt file and save it in the /toolkit-lib/lib folder. Ports are set on the device by the properties proxy.udp_device_detection_request_port and proxy.udp_device_detection_response_port. Terminate an application which uses these ports.Ĭonfigure the board and Java ME SDK to use different ports. By default, they are UDP IPv4 ports 5529. The ports used for IP-based device detection are busy on the host machine. The SDK device-manager.log is full with the following error messages: The board IP address is not shown by default in the Java ME SDK Device Manager "Add Device" dialog. It is recommended that you stop other applications that consume memory resources and then proceed with the installation of a big MIDlet. There is not enough memory for AMS operation. Installation of a big MIDlet results in the error "AMS generated out of memory". The exact procedure to open a port differs depending on your version of Windows or your firewall software.Ĭlose thunderbird.exe during the debugging session. Open TCP port 2808 on your firewall configuration settings. Thunderbird is using a port that is needed for communication with the board. ![]() The firewall on the computer is blocking some debugging traffic. The debugging session freezes, disconnects unexpectedly, or shows error messages. ![]() Also, if the Developer Agent program runs in a client mode, ensure that the proxy.client_connection_address property is properly configured to use the Developer Agent program's host address. Ensure that the Socks field is empty and the Use the same proxy server for all protocols check box is not selected.Įnsure that the +UseProxy parameter is present in the run.sh script. The socket proxy needs to be disabled: Open the Proxy Settings window available by clicking the Advanced button on the LAN Setting window. The proxy connection is not enabled or an improper proxy host address is set up in the jwc_properties.ini file. LAN proxy settings of the host might be a source of the problem. The board is not detected when adding a new device to the Device Selector. Table 3-3 Problems and Solutions: Oracle Java ME SDK and the NetBeans IDE Problem ![]()
