Summary

SOAP (the Simple Object Access Protocol) is a way for a program running in one kind of operating system (such as Windows 2000) to communicate with a program in either the same or a different operating system (such as Linux) by using HTTP and XML as the mechanism for information exchange. Java and SOAP introduces Java developers to the Simple Object Access Protocol for designing and implementing web services. It surveys the existing technology and protocols that SOAP leverages and why they are important, the types of distributed systems that can benefit from SOAP, and the issues that Java developers need to consider when developing SOAP software.
