Package oracle.adf.model.servlet Description

Contains the ADFBindingFilter implementation.

ADF web applications use the ADF binding filter to preprocess any HTTP requests that may require access to the binding context. The binding filter is a servlet filter, which is an instance of the oracle.adf.model.servlet.ADFBindingFilter class. When you add a databound UI component to a page using the Data Control Palette, JDeveloper automatically configures the filter in the application's web.xml file. The binding filter performs the following functions:

• Overrides the character encoding when the filter is initialized with the name specified as a filter parameter in the web.xml file. The parameter name of the filter <init-param> is encoding.
• Creates the ADFContext, which is the execution context for an ADF application and contains context information about ADF, including the security context and the environment class that contains the request and response object.
• Initializes the binding context for a user's HTTP session.
• Serializes incoming HTTP requests from the same browser (for example, from framesets) to prevent multithreading problems.
• Notifies data control instances that they are about to receive a request, allowing them to do any necessary per-request setup.
• Notifies data control instances after the response has been sent to the client, allowing them to do any necessary per-request cleanup.

To configure the binding filter in the web.xml, JDeveloper adds the following elements:

• A servlet context parameter
• The ADF Binding Filter Class
• Filter Mappings
