java.lang.Objectjavax.servlet.ServletResponseWrapper
@TransactionType(value=NOT_SUPPORTED) public class ServletResponseWrapper
Provides a convenient implementation of the ServletResponse interface that can be subclassed by developers wishing to adapt the response from a Servlet. This class implements the Wrapper or Decorator pattern. Methods default to calling through to the wrapped response object.
