In the Number Guess application you get given 10 attempts to guess a number between 1 and 100. After each attempt, you will be told whether you are too high, or too low. This example can be found in the examples/se/numberguess folder of the Web Beans distribution. -There is an empty beans.xml file in the root package (src/main/resources/beans.xml), which +There is an empty beans.xml file in the META-INF package (src/main/resources/META-INF/beans.xml), which marks this application as a Web Beans application.
