Presented by developerWorks, your source for great tutorials

Assuming that the EJB component and the WAR files are deployed in the same EAR

file, the above would add an EJB reference to the Hello EJB component. You need two

more files for this example. Unzip the sample source, find

happy.jsp

and

index.html

in

the

Hello

example directory (under

web

), and copy

happy.jsp

and

index.html

into the

web

directory (

C:\tutorials\axisEJB\axisEJBHello\web

). You will use these files to see a

list of Web services deployed in your Web application and to see if everything is

correctly setup.

Create Web Service Deployment Descriptor for EJB

component

So far you have downloaded and installed the ETTK. Then you created a simple EJB

component called

Hello

. Then you created a Web application. You configured the Web

application s

web.xml

file to use Axis as the SOAP transport. You also configured the

Web application to refer to your EJB component called

Hello

.

You need a way for Axis to know that you want to expose your EJB component as a

Web service. You can accomplish this with an Axis Web Service Deployment

Descriptor (WSDD). The WSDD needs the ability to state the following about your EJB

component: What kind of service?, Where to look for the service?, What is the structure

of your EJB component?.

Thus you need to state the following:

1) What Kind of service?

This service is EJB based

2) Where to look for the service?

The JNDI Context factory class for your EJB application server

The JNDI URL of your EJB application server

The home JNDI name of your EJB component

3) What is the structure of your EJB component?

The remote interface of the EJB component

The home interface of the EJB component

All of the above questions are answered with the Web Service Deployment Descriptor
