The order in which filters are invoked is the order in which filter-mapping declarations that match a request URI for a servlet appear in the list of filter-mapping elements.
WAR (file format) – Wikipedia
Within global complexTypes It consists of an optional description, the resource environment reference name, and an indication of the resource environment reference type expected by the Deployment Component code. This allows multiple enterprise beans with the same ejb-name to be uniquely identified.
JSP can be used independently or as the view component of a server-side model—view—controller design, normally with JavaBeans as the model and Java servlets or a framework such as Apache Jj2ee as the controller. The logical name of the filter is declare by using filter-nameType.
The message destination element contains: Declares the handler for a port-component. The elements that use this type should include any information that the Deployment Component’s Deployment File file producer wants to provide to the consumer of the Deployment Component’s Deployment File filethpe. Use this method when you are sure the parameter has only one value; otherwise use getParameterValues.
All elements may occur multiple times with different languages, to support localization of the content. The declaration consists of an optional description, the security role j2fe used in the code, and an optional link to a security role. The extension element contains a string describing an extension.
The declaration consists of an optional description, the name of the environment entry, and an optional value. The include-prelude element is a context-relative path that must correspond to an element in the Web Application. It is legal to name the same encoding through mulitple mechanisms.
WAR (file format)
If the value is a negative integer, or the element is not present, the container is free to load the servlet whenever it chooses. Context means application scope.
Filetyoe lang attribute defines the language that the description is provided in. The users of flletype type should further verify that the content does not contain Java reserved keywords. The absence of any dispatcher elements in a filter-mapping indicates a default of applying filters only under ordinary client calls to the path or servlet. The type is specified by the Java interface expected to be implemented by the destination.
The servlet-mappingType defines a mapping between a servlet and a url pattern. The login-configType is used to configure the authentication method that should be used, the realm name that should be used for this application, and the attributes that are needed by the form login mechanism.
It must follow the rules specified in Section The url-patternType contains the url pattern of the mapping. The getInitParameterNames method retrieves the names of the servlet’s initialization parameters as an Enumeration of string objects. This header allows the servlet to specify information about the file’s presentation.

The location is relative to the root of the module. The container must guarantee that servlets marked with lower integers are loaded before servlets marked with higher integers. The include-coda element is a context-relative path that must correspond to an element in the Web Application.
You can also suggest the filename to be used if the content is to be saved to a file. The message-destination-ref-name element specifies the name of a message destination reference; its value is the environment entry name used in Deployment Component code. JavaWorld Reprinted by Oracle Corporation. The form-login-page element defines the location in the web app where the page that can be used for login can be found.

Let’s practice with a PDF document. If the security role is not specified, the Deployer must choose an appropriate security role. The value must be one of the two following: You may 2jee use this file except in compliance with the License. It can be a combination of JSP pages, servlets, tag libraries, Java beans, and other class files.
The message-destination-usageType specifies the use of the message destination filetgpe by the reference. The port-name element defines the WSDL port-name that a handler should be associated with. To determine which filters to apply it matches filter-mapping declarations either on j2eee, or on url-pattern for each filter-mapping element, depending on which style is used.
The ejb-linkType is used by ejb-link elements in the ejb-ref or ejb-local-ref elements to specify that an EJB reference is linked to enterprise bean. Declaration of the filter mappings in this web application is done by using filter-mappingType.
