INTERACTIVE WEB SERVICES WITH JAVA

The Service Class

A Service object corresponds to an instance of an installed service and contains:

• shared data, which are simply the fields in the object
• an inner class for each kind of session offered to the clients

The Service class offers the following features:

• checkpoint() and rollback() of the shared state (using serialization)
• handling of cookies (for use by the programmer, not for encoding session ID!)
• logging of events
• setting of timeouts
• SSL support
• blocking of incoming requests
