Install the EJB home and component interface compiled classes on your ColdFusion web server,

either as class files in the web_root/WEB-INF/classes directory or packaged in a JAR file the
web_root/WEB-INF/lib directory.
Note: To use an EJB served by a JRUN server, your ColdFusion installation and the JRun server that
hosts the EJB must have the same version of the jrun.jar file (located in cf_root\runtime\lib directory in
ColdFusion).
While the specific steps for using an EJB depend on the EJB server and on the EJB itself, they
generally correspond to the following order:
To use an EJB:
Use the

cfobject
(javax.naming.Context). You will use fields from this class to define the information that you
use to locate the EJB. Because you only use fields, you do not initialize the object.
Use the
tag to create a java.util.Properties class object that will contain the context

Set the Properties object to contain the properties that are required to create an initial JNDI

naming context. These include the INITIAL_CONTEXT_FACTORY and
PROVIDER_URL properties. You might also need to provide SECURITY_PRINCIPAL and
SECURITY_CREDENTIALS values required for secure access to the naming context. For
more information on these properties, see the JNDI documentation.
Use the
tag to create the JNDI InitialContext (javax.naming. InitialContext) object.

or more existing entity beans.
Now you can use the bean's methods as required by your application.
