Java and Web Services

SDK.AlthoughJavaEEisthepreferred approach fordeveloping webservices froma
production perspective, because Java EE-based servers provide a very high degree of
scalability, a security infrastructure, monitoring facilities, and so on, the repeated de-

development.
Java 6 simplified and accelerated web services development by incorporating APIs,
