JVending Description
JVending is a P2P (JXTA) based mobile content provisioning system. JVending project bridges P2P networks and wireless delivery of content to mobile devices. Due to high latency of wireless connections, it is not practical to directly hook up the mobile devices to the peer network, so I have taken a different approach with JVending.A user sets up a personal provisioning server on their PC and hooks it into the network. Through the P2P network, we create a federation of provisioning servers. The mobile devices use the federated provisioning servers as content portals.JVending differs from P2P systems, such as Gnutella or "Project JXTA" reference implementation, in the following ways. JVending provides:1. Catalog management2. Device detection, which delivers the appropriate content based upon the type of browser or device3. Web based browsing of content, so you can share with your friends on a wired or wireless network, after you have already collected the content.4. The ability to search for and distribute packaged archives on the peer network.5. Web links tying together the network.6. PPG integration for pushing content to mobile devices.For 2005 - 2006, the major goals of JVending (roughly in order of importance) are:1. Expanding P2P support, including more in the area of wireless messaging (SMS)2. JSR-124 compliance3. Performance testing and monitoring capability4. Multimedia server and J2ME support. This covers full integration between the MMS Client and the provisioning server.Setting up the EnvironmentFollow these steps:1. Make sure that you have J2SE 1.4.2 JDK installed. If not, go to http://java.sun.com/j2se/1.4.2/download.html and download and install the JDK (not JRE). I have not tested with J2SE 1.5 JDK, so it may or may not work with that version.2. Download the jvending-standalone.zip file from the JVending project site.3. Unzip the file into a directory of your choice, say /jvending4. Set the JAVA_HOME environmental variable, depending on your OS. In windows, you can do this through the Control Panel/System/Advanced/Environmental Variable: JAVA_HOME = EXAMPLE: JAVA_HOME=c:Programsj2sdk1.4.2_06Starting JVending1. Go to the bin directory and click on the run.bat (for windows) or run.sh for Unix.2. The first time you start JVending, you will see a JXTA Configurator screen show up. Type in your user name and password/verify password. Click OK. 3. Wait 10 seconds for JVending to finish its startup sequence and then go to http://localhost:80/jvending/login. If you get a 404 error, wait a few more seconds and try again. Login ID/Password: admin/admin. Click "Submit Query" button. You will now see the JVending home page.
