9.4. Paper and Pencil
Apache Axis is a next-generation SOAP engine. This exercise is meant to have you practice using Apache Axis to expose an existing interface as a Web Service.
Apache Axis has a different architecture design from previous versions of Apache SOAP. It can generate SOAP client and server components directly, without using a third-party developer IDE/workbench tool.
Using the Foreign Exchange Spot Rate Quote example in Chapter 8, Web Services in Action Case Study, you are to expose the interface as a Web Service using Apache Axis's utilities java2wsdl and wsdl2java.
