remote interface

When a client wants to use a bean, the container "finds" that instance in its pool of beans and returns the Remote interface for that bean.

In the HelloWorldSessionBean class, but do not promote it to the remote interface since it does not need to be exposed to the client.

For EJB service implementation, the SEI methods must be a subset of the EJB component's remote interface methods.

With the EJB-compatible business interface in place, the next step is to extend it in your remote interface.

When launching the EJB test client, a wizard will pop up ask you to select the Local or Remote Interface of the EJB.

The remote interface of the Human Task Manager is shown in Figure 2 to illustrate the overall communication.

The remote interface, retrieved through the home interface, gives you access to the public methods of the remote object.

The Web browser client will never interact with the entity bean directly, not even with its remote interface.

Why would you want to provide a remote interface to an entity EJB component when a well known best practice is to use a facade?

All you've added is an annotation declaring this to be a remote interface.

Care must be taken to ensure that methods declared in the remote interface are actually implemented in the EJB remote implementation class.

Also note that a completely machine-readable description of a contract for a remote interface is a fallacy.

Listing 3 shows what the remote interface would look like if it were built using the Business Interface pattern.

My solution to this is to place the remote interface into a common subpackage of client.

This business method is added to a remote interface to give clients access to this method.

Even if those names match with the correct remote interface and the bean class, these files must be browsed again.

You add the method to your bean implementation class, but then forget to add it to the remote interface.

It only needs to implement a remote interface that you define or allow your IDE to create automatically.

It must not implement (directly or indirectly) the java. rmi. Remote interface.

AccountValue -- a transfer object that represents account information obtained from the Account entity bean remote interface.

In the Send with deferred response dialog, call the sending method name: orderBook, and select Add to remote interface.

Finder methods return the bean's Remote interface or an enumeration of Remote interfaces.

When an instance of CustSession remote interface appears on the left side of the page, expand it see its methods.

The AAT uses Java's reflection APIs to probe the remote interface and home interface classes.

Having obtained the remote interface, you can call the methods that make up your actual EJB code.

Otherwise, the value object is a carbon copy of the bean's remote interface.

An enterprise Bean's remote interface provides the remote client view of an EJB object.

Follow the steps below to promote these methods to the remote interface.

All service endpoints must extend the java. rmi. Remote interface.

To obtain the remote interface from the application server.

Button, the remote interface and the bean class are automatically filled in.

Promote the relevant methods to the remote interface.

The remote interface of the service implementation bean should be _RI. java (such as Calculator_RI. java).

TestRemote -- Calls the session bean remote interface via lookup of EJB reference .

Now the methods that were added to the remote interface of the Library bean can be tested.

If you use entity beans in this context, avoid giving them a remote interface.

In addition, you aren't required to code the home interface, remote interface, and local interface classes.

Add the following three business methods to the HelloWorldBean and then promote them to the remote interface.

The value object in Listing 2 looks almost identical to our remote interface, but it's actually a concrete class.

EJBs that are location-independent use a remote interface.

The asynchronous interface must also live in the same package as the remote interface.

The Geronimo server will locate the actual EJB based on the home and remote interface and the EJB type specified.

Promote the two methods to the remote interface as described in Step 6.

A simple utility class is created to easily get the instance of the async remote interface (lines 7-13 in Listing 8).

By default, all methods on the EJB remote interface have a transaction setting of TRANSACTION_REQUIRED (see Figure 10).

The services don't know a remote-interface or a RemoteException (how RMI).

For example, you can capture all RMI calls by specifying operations throwing RemoteException in a class implementing the Remote interface.

It's developed based on the EJB remote interface.

For example, utility methods on the implementation class don't have to exist on the remote interface.

The second part is the addition of two valuable methods to our remote interface, as shown in Listing 3
