13.3.1 Defining EJB JNDI names
For each session and entity bean, specify a JNDI name. This name is used to bind the EJB home object to an entry in the global JNDI name space. The bind happens automatically when the appserver starts.
You can bind your EJBs anywhere you want in the JNDI name space, but best practice dictates they should be bound under the ejb subcontext, such as ejb/Order for the Order EJB. However, the Plants by WebSphere binds its EJBs to the plantsby subcontext in the JNDI root, so this is what we will show you here.
For clarity, however, when developing your own application, we recommend that you place all enterprise bean JNDI names for an application in a separate subcontext, such as ejb/PlantsBy. You can find the JNDI names for the Plants by WebSphere session and entity EJBs in Table 13-1.
