The registered presentation handler is responsible for processing the reply to the HTML client. The main API provided by this class is void processReply(ChannelContext, ServerOperation). This starts the process of dynamically creating the HTML and rendering it to the client using the servlet JSP engine.
This class is used by the RequestValidationServices. It encapsulates the objects that are used when processing a request from an HTML client. The objects encapsulated are the operation, the channel context, and the operation completion time.
The HtmlConstants class defines all the constants required by the HTML Channel, including the key strings that are used in contexts, hidden fields, and HttpServletRequest attributes. See the Javadoc for this class for information about these constants.
This class provides the implementation of request validation, protecting the user from an unintentional duplicate request or a back click to a page that corresponds to a finished or expired process.
This interface defines the protocol to be used by the JSP files for interaction with the context involved with the current request, to set hidden fields in the request, to support exception messages, and other related tasks.
This class implements JspContextServices. It can be instantiated on a JSP with the useBean tag. This class receives the operation context from the request and then extracts information from the context and emits it to the page as hidden fields. It has other methods to support exception messages, URL rewritten links, and to obtain the session and operation Context objects.
