Make It Work!
Download source code and unzip it anywhere you like. Because you're using Ant as the build tool, almost everything will be done automatically. However, you need to change the path names to fit your own settings. Open the build.xml file with your favorite editor and navigate to the following lines on the top:
Figure 4: The build.xml File
- jboss.cfg is the configuration in which you'll run your JBoss application server. It could be default, all, and minimum. If you're not making any other changes to your application server configuration, it's best to just stay with default.
- jboss.home is where your JBoss application server is located.
- axis.home is the path to the unzipped Apache Axis distribution.
Now you're ready to launch JBoss application server, and compile, build, and deploy code in it. Remember, this article assumes that you are running your JBoss on http://localhost:8080, but if something is different, say, the port number, you will have to change these values yourself in the files client/StandaloneClient.java and war/web/access_soap.jsp.
Next, type only three commands:
-
ant (to compile and pack EAR)
-
ant deploy (to deploy built code)
-
ant clean (to clean all built classes)
You should see the following screen:
C:\_NR\_articles\ejbaxis\src>ant
Buildfile: build.xml
compileejb:

Total time: 0 seconds
C:\_NR\_articles\ejbaxis\src>
In your JBoss application logs, you should see something like in Figure 5:
Figure 5: Deployment Information
You're up and running! To test the program, type http://localhost:8080/ejbaxisdemo/
into your browser window, and you will see page with two choices: to see how the JSP will work with the EJB directly and how it will work with the EJB as a Web service. Click around and see how each interacts with the EJB and which responses they get (hint: they should be the same). In your JBoss logs, you will see some debug information.
Now you need to try this on the standalone Java-client. Type the following:
-
ant client to compile
-
ant run to run it and see how it works
You should see
C:\_NR\_articles\ejbaxis\src>ant client
Buildfile: build.xml
client:
[echo] **** Compiling Standalone Client...
[mkdir] Created dir: C:\_NR\_articles\ejbaxis\src\build\client\classes
[javac] Compiling 1 source file to C:\_NR\_articles\ejbaxis\src\build\client\classes
BUILD SUCCESSFUL
Total time: 2 seconds
The running screen output should look like Figure 6.

Extending Your Enterprise Apps
Apache Axis is a pretty powerful and flexible SOAP implementation. It has many more options, abilities, and advantages than described in this tiny article. However, it still provides a very nice service—even without any special configuration, so you can extend your existing enterprise applications with Web Services quickly.
