  2. Install OpenJDK 7

  4. You must then start the installation :
    java - jar wlp-developers-runtime - 8.5.5.2.jar

  6. Go to the directory of the executable WLP/bin. This is where you can create a server. After the create parameter, Scroll to the name you want.
    ./Server create pihomeserver
  7. By default the server runs on port 9080 and does not accept any connection apart from localhost. To change, It is in the file usr/servers /.<Server name>/Server.XML.
    For remote access, You must add a host clause in the block httpEndpoint. I put a clause to accept all connections.

    host ="*"

    <webApplication contextRoot ="pihome" location ="PiHomeServerWeb.war" />

    The war file must be deployed in the sub directory apps Server.

  8. You can then start the server.
    ./Server start pihomeserver

  9. If you go to the directory where you have the installation, you will find the directory dedicated to your server. It is necessary to return to the directory usr/servers /.<Server name> :

  10. To deploy your application, you copy the file war in the directory apps. It must have the same name as configured in the application in the server.xml file.
  11. Go to your Pi Raspberry with your favorite browser : http://<ip>:<port in server.xml>/<contextRoot in server.xml>
