How to access Session Bean from JSP in GlassFish

Using Session Bean in JSP differs from the usage in servlets. We can inject session bean in servlets or in another session bean. But in JSP we can not use EJB in the same way. Most common approach would be a JNDI lookup to  find the required bean.

First add a reference in deployment descriptor to the session bean.

<ejb-local-ref>
<ejb-ref-name>AccountTypeFacadeRef</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<local>com.my.ejb.AccountTypeFacade</local>
<ejb-link>BankApp-ejb.jar#AccountTypeFacade</ejb-link>
</ejb-local-ref>

is optional.

In JSP use JNDI lookup to find the resource.

<%
String prefix = "java:comp/env/";
String ejbRefName = "AccountTypeFacadeRef";
String jndiUrl = prefix + ejbRefName;

javax.naming.Context ctx = new javax.naming.InitialContext();
AccountTypeFacade atf = ( AccountTypeFacade ) ctx.lookup( jndiUrl );
List<AccountType> accountTypeList = atf.findAll();
%>
