After you have created an EJB 3.1 applications, you can
create a Servlet or JSF to test the EJB 3.1 applications.
Testing EJB 3.1 applications with a servlet
To test an EJB application with a servlet, you must first inject
an EJB reference using the
@EJB injection annotation
from EJB 3.1. Once you have injected the EJB, you can call the methods
that are available from the Remote or Local interface.
- Select and select Servlet.
- Type the package and class name for your servlet.
- After the servlet has been created and the Java™ editor opened on the servlet class, insert
the @EJB annotation tag along with the reference
to the local or remote interface class as a new field in the servlet.
- You can now invoke any of the methods in the local or remote interface
from within the doPost() or doGet() methods of your servlet.
The following snippet is taken from the EJB 3.1 Counter sample.
You will see the
statelessCounter field is declared
with the type being
LocalCounter which is our local
interface for the EJB. The
@EJB annotation in front
of it injects an instance of it into our servlet.
// Use injection to get the ejb
@EJB private LocalCounter statelessCounter;
Testing EJB 3.1 applications with a JSF file
This type of testing currently requires some manual configuration
steps. For an example of the code involved, import the EJB 3.1 Counter
sample from the information center and locate the EJBCounter.jsf file in the WebContent folder as well as the
page code Java classes in the Java sources in the EJBCounter.jsf project.
