B4J Question Exception with example DataCollectionServer

Open the command console (cmd.exe) and go to the app folder. Run java -jar DataCollectionServer.jar

It will show you more information about the error. The problem is probably with the Java version. It should be Java 7+.

AddHandler is explained here: [Server] Building web servers with B4J

questo è l'errore?!
