    Apache AXIS with IBM's WSAD/RAD

    All major IDEs from different Vendors support webservices using Apache Axis.In this post my objective is to demonstrate a simple web service development and deployment using IBM's Websphere Application Developer(WSAD)/Rational Application Developer(RAD).They both provide support for Apache Axis and can use Axis libraries as required for runtime environment for web services.

    In following heads all the steps involved are explained:

    Configure Axis as runtime for Web services in RAD

    -Start RAD/WSAD. Open a new workspace, and close the welcome screen.
    -In WSAD/RAD,go on menu, Window >Preferences >Web Services >Server and Runtime
    Do the settings for Apache Axis runtime as shown in the Figure 1.

    Figure 1

    Create a new Web Project

    Now we have a plain java class and a web project. Next step is to create a web service out of this class and embed it into this Web project
    -Switch to J2EE perspective, and create a new Dynamic Web project with name 'AxisExample'.

    Figure 2

    Create a simple java class which you want to expose as a web service.

    Figure 3

    Write any method which you want to access through WebService

    Figure 4

    Now you have a simple java class and a web project. The next step is to create a web service out of this class and embed it into this Web project.

    For creating Web Service switch to J2EE Perspective

    Figure 5

    Select wizard to create a Web Service

    Figure 6

    Select Web Service type as desired (in this case select Java Bean Web Service)

    Figure 7
    Select the class created earlier as Java bean

    Figure 8

    If you select to generate proxy then the wizard will also ask you to select client type, for which proxy is to be generated

    Figure 9

    In this step you may have to manually select Axis as runtime if not default selected. And also you have to select the Web project just created as service project and also the server instance on which you want deploy this Web Service

    On clicking next, a warning will pop up Ignore this warning, this is because RAD uses an older version of axis.

    Figure 10

    Now we are ready to generate and deploy the web service !

    Figure 11

    If you want to test this service, click on launch in next screen.

    Figure 12

    And you get the output as shown in the figure 13 in web-browser

    Figure 13

    Now let us generate proxy for this web service through wizard

    Figure 14

    Select the methods you want to add in the proxy generated
