Accessing J2EE Applications from Portal Applications (SAP Library

Accessing J2EE Applications from Portal Applications

Procedure

Portal applications can access J2EE applications such as EJBs and servlets. To do this:

1. Specify the reference

The reference is defined in portalapp.xml either in PrivateSharingReference or PublicSharingReference using the SAP J2EE application prefix "SAPJ2EE::"

Example

2. Access the application

The application is accessed via JNDI. The following is an example of a portal component accessing an EJB

Example

public void doContent(

IPortalComponentRequest request,

IPortalComponentResponse response) {

String key = "Hello/Stateless/HelloStatelessBean";

try {

Context context = new InitialContext();

Object obj = context.lookup(key);

HelloHome home =

(HelloHome) P4ObjectBroker.init().narrow(obj, HelloHome.class);

Hello hello = home.create();

response.write("Bean message: " + hello.getMessage());
