Develop SessionBean

Perform the following steps:
1. Establish a test web module
2. Create an idea ejb module and compile an ejb
3 compile and package
4. Write test page
5. Release ejb, web test module, and test ejb
1. Establish a web test module.
In the default user_projectsdomainsmydomainapplications Directory, create a folder named web. This folder is the web module for testing ejb.
Create a new WEB-INF folder under the web folder and a new lib folder under the WEB-INF.
Create a web. xml file in the WEB-INF with the following content:
<? Xml version = "1.0" encoding = "UTF-8"?>
<! DOCTYPE web-app PUBLIC "-// Sun Microsystems, Inc. // DTD Web Application 2.3 //" http://java.sun.com/dtd/web-app_2_3.dtd ">
<Web-app>
</Web-app>
OK. The web test module is complete.
2. Create an idea ejb module and compile an ejb
Open idea, select file-new-ejb modules, and change module name to "EjbSamples", as shown in the figure below:
In the server option, select weblogic, and the rest are set by default. Click finish.
Create a new package in the src folder. Package name: com. diegoyun. ejb. slb, as shown in the following figure:
Right-click the module name and choose new-sessionBean from the shortcut menu. Then, in the pop-up property box, set as follows:
<Ejb-name>: enter Helloworld.
Package: Select/enter com. diegoyun. ejb. slb
The remaining information idea will be automatically set for you. The attributes of the entire attribute box are as follows:
Click OK.
In this case, the ejb attribute configuration interface is displayed, as shown in the following figure:
In Display name, enter HelloworldEJB
Switch to the weblogic server page and enter the following jndi name: ejb/session/HelloworldEJB.
The interface is as follows:
Close this property page. Idea has helped you write the configuration information of ejb. You can open META-INF and ejb-jar.xml under weblogic-ejb-jar.xml/for viewing.
At this time, under com. diegoyun. ejb. slb, there should be three files: Helloworld, HelloworldBean and HelloworldHome.
Add a method to the Helloworld interface as follows:
Public interface Helloworld extends EJBObject {
Public String getGreeting (String name) throws RemoteException;
}
Add a method to the HelloworldBean interface as follows:
Public class HelloworldBean implements SessionBean {
...............
// Omit others
Public String getGreeting (String name ){
