Web Services Performance: Comparing Java 2 Enterprise Edition (J2EE platform) and .NET Framework

Web services are Web-based enterprise applications that use open, XML-based standards and transport protocols to exchange data with calling clients. Web services are becoming the most important technology for communications between disparate applications in different enterprises.
