An external properties viletype would define the link with some thing like:. When there are multiple elements of welcome-file-list or locale-encoding-mapping-list, the container must concatinate the element contents.
It is used by display-name elements.

This allows multiple enterprise beans with the same ejb-name to be uniquely identified. The welcome-file element contains file name to use as a default welcome file, such as index. This can be done to override implicit map entries from TLD files and from the container. 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.
The compiled pages, as well as any dependent Java libraries, contain Java bytecode rather than machine code. This is a broad-stroke objective. The env-entry-value designates the value of a Deployment Component’s environment entry.

It is not specified if no wsdl-file is declared. Deployment Component may indicate one of the following: The location is relative to flietype root of the module.
The security-roleType contains the definition of a security role. The param-value element contains the value of a parameter.
The logical destination foletype by this element is mapped to a physical destination by the Deployer. The type is specified by the fully qualified Java language class or interface expected to be implemented by the data source.
It is used by env-entry elements. Alternatively, the value may be composed of a path name specifying a Deployment File containing the referenced message destination with the message-destination-name of the destination appended and separated from the path name by filegype “. The getInitParameter and getInitParameterNames methods retrieve context-wide, application-wide, or “Web application” parameters.
It is legal to name the same encoding through mulitple mechanisms.
The classpath consists of a list of locations from which. The include-coda element is a context-relative path that must correspond to an element in the Web Application. The security-constraintType is used to associate security constraints with one or more web resource collections Used in: You access the ServletContext for information about the application state. Each servlet name is unique within the web application. Context means application scope.
The interface that defines the form parameter methods is ServletRequest. Likewise, content inside a loop construct may appear multiple times in the output, depending upon how many times the loop body runs. This section tells you how to write these routines that perform actions such as retrieve HTML form parameters, request headers, servlet initialization parameters, and redirects.
The declaration consists of: The Assembler sets the value to reflect the flow of messages between producers and consumers in the application.
This is where the browser specifies the file wanted, date, image file support, and more. This header allows the servlet to specify information about the file’s presentation. The icon can be used by tools. If this element is not specified, the container must set its default timeout period.
Content that falls inside a split block of Java code spanning multiple scriptlets is subject to that code. A taglib-uri element describes a URI identifying a tag library used in the web application. This type adds an “id” attribute to xsd:
