The temperature-converter
quickstart does temperature conversion using an EJB Stateless Session Bean (SLSB), CDI, and a JSF front-end client.
The temperature-converter
example demonstrates the use of an EJB Stateless Session Bean (SLSB) and CDI, accessed using a JSF, and deployed to {productNameFull} using a WAR archive.
The application does the following:
-
The User Interface is a JSF page that asks for a temperature and a scale (Fahrenheit or Celsius).
-
When you click on
Convert
, the temperature string is passed to the TemperatureConverter controller (managed) bean. -
The managed bean then invokes the
convert()
method of the injected TemperatureConvertEJB (notice the field annotated with @Inject). -
The response from TemperatureConvertEJB is stored in the
temperature
field of the managed bean. -
The managed bean is annotated as @SessionScoped, so the same managed bean instance is used for the entire session.
The application will be running at the following URL: http://localhost:8080/{artifactId}/.
You will be presented with a simple form for temperature conversion.
-
Optionally, Select a scale: Celsius or Fahrenheit.
-
Enter a temperature.
-
Press the
Convert
button to see the results.
