Filters can access the initialization parameters declared in the deployment descriptor at runtime via the FilterConfig interface. It can be a combination of JSP pages, servlets, tag libraries, Java beans, and other class files.

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 ” “.

The value, if specified, must be one of the two following: The location element contains the location of the resource in the web application relative to the root of the web application.

Some parameters have no information, so this method will return a string containing at least the Servlet Container name and version number. This type defines four different values which can designate boolean values.

If a jsp-file is specified and the load-on-startup element is present, then the JSP should be precompiled and loaded. Like any other Java program, they must be executed within a Java virtual machine JVM that interacts with the server’s host operating system to provide an abstract, platform-neutral environment.


All elements may occur multiple times with different languages, to support localization of the content. A role-name-key is specified to allow the references from the security-role-refs. The session-configType defines the session parameters for this web application. This page was last edited on 15 Decemberat There should be no entries in web.

The four methods associated with getting parameters are.

My name is Duke. What’s yours?

If you don’t specify the filename, you are likely to get the name of your servlet in that box. The run-asType specifies the run-as identity to be used for the execution of a component.

The path name is relative to the Deployment File containing Deployment Component that is referencing the enterprise bean. The name must be unique within the module. The include-prelude element is a context-relative path that must correspond to an element in the Web Application. The local-homeType defines the fully-qualified name of an enterprise bean’s local home interface.

The ejb-local-refType is used by ejb-local-ref elements for the declaration filetypr a reference to an enterprise bean’s local home.

The env-entryType is used to declare an application’s environment entry. The ejb-refType is used by ejb-ref elements for the declaration j2se a reference to an enterprise bean’s home. It is used by env-entry elements. Architecturally, JSP may be viewed as a high-level abstraction of Java servlets. Declares the handler for a port-component. The role-link element must contain the name of one u2ee the security roles defined in the security-role elements. 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 jee a framework such as Apache Struts as the controller.


The res-authType specifies whether the Deployment Component code signs on programmatically to the resource manager, or whether the Container will sign on to the resource manager on behalf of the Deployment Component.

If there aren’t any, it returns an empty Enumeration. Java enterprise platform Java specification requests Template engines.

The Web container creates JSP implicit objects like m2ee, response, session, application, config, page, pageContext, out and exception. The security-role-refType contains the declaration of a security role reference in a component’s or a Deployment Component’s code.

When the element is present, the j2fe path will be automatically included as in an include directive at the end of each JSP page in this jsp-property-group. The definition consists of an optional description of the security role, and the security role name.

It contains a declaration of a Deployment Component’s reference to an administered object associated with a resource in the Deployment Component’s environment.

The multiple occurance of the element distributable is redundant and the container treats that case exactly in the same way when there is only one distributable.

Parameters are filehype in the query string or posted form data.
