Introduction

Included in the JWSDP are a set of tools that can be used in the development or deployment of Web services. These tools can be employed to support a development server, and can even be used for some production releases. The tools include a UDDI registry (Java WSDP registry server), a servlet/JSP container (Tomcat), and a build tool (Ant).

The Java WSDP registry server is least likely to be used in production environments at least in its current form. It has limitations in the scope of UDDI supported, its capability to provide highly available services, and in its performance. These will likely be addressed in future releases, so it will be interesting to see if it eventually evolves into a production-level tool.

Tomcat is a much more capable tool. Behind IBM s WebSphere and BEA s WebLogic, it represents one of the most accomplished and up-to-date servlet engines. It may even be suitable for small production environments. This depends on your overall willingness to assume risk, of course. Tomcat is generally supported by open-source volunteers, and does not provide high-availability features.

If used in development, Ant is the tool you would likely continue to use as you moved toward production. As a build tool, the issues of high availability are moot. Ant is as capable a tool for Web services as any other make utility perhaps even more so. Keep in mind that it s a very different tool than standard make utilities, and does...
