Section 2. Step by step Hello World example

Steps

Prime your engines by creating a simple EJB component that uses Axis to expose itself

as a Web service. To do this you will need to perform the following steps:

1. Download and install the ETTK

2. Create a simple EJB component

3. Create a Web application and configure its deployment descriptor (

web.xml

)

4. Create a Web service deployment descriptor for your EJB component

5. Use Axis Ant tasks to deploy the EJB based Web service

6. Use Axis Ant task

wsdk2java

to generate client stubs

7. Write a Web service client for your EJB component

8. Work with Local EJB Services.

Download and install the ETTK

Read this complete page before starting the ETTK download.

Go to

http://www.alphaworks.ibm.com/tech/ettk

and download the install file

ettk10.exe

.

Once the install file is downloaded, run it with all the default options. This should install

the ETTK in the directory

c:\ettk

. The rest of this tutorial assumes the ETTK is installed

in the location

c:\ettk

, so please adjust accordingly.

Unlike the older version of the ETTK (called the Web Services ToolKit or WSTK), this

version does not ship with a default application server which the install package needs.

You will need to install Tomcat 4.0 (or one of the other approved application servers).

To make the ETTK install happy please download and install Tomcat 4.0. Then point

the ETTK install to the Tomcat 4.0 directory when it prompts you. Tomcat 4.0 can be

found at

http://jakarta.apache.org/builds/jakarta tomcat 4.0/release/v4.0.6/bin/

.

Since this tutorial uses EJB technology, you will need another application server that

supports EJB components. The examples in this tutorial use Resin EE. However it

should be easy for you to port to another application server. If you are not in the mood

for porting, please download and install Resin EE 2.x at this time from

www.caucho.com

. Install Resin EE in

c:\resin

.

If you do not have Ant, now is a good time to install it as well. You can find Ant at
