Extensions

Lets you specify settings for WebSphere extensions (such as enabling reloading).

Source

Lets you edit the web.xml source directly.

Editing the XML source directly is not the recommended method for editing the deployment descriptor. The best way to build deployment descriptor files is to edit the multiple tabbed pages. As you specify deployment information in these tabbed pages, the editor automatically incorporates the appropriate XML tagging.

In addition to the configuration information in the web.xml file, other deployment descriptors in a Web project include the following information:

Binding information — information is required by the application server to bind the deployment information specified in the application to a specific instance. For example, it may map a logical name of an external dependency or resource to the actual physical JNDI name of the resource. It also may map security role information to a set of groups or users.

IBM binding and extensions information (ibm-web-bnd.xmi and ibm-web-ext.xmi files) — additions to the standard descriptors for J2EE applications, Web applications, and enterprise beans. The extensions enable Enterprise Edition or legacy (older) systems to work in the current WebSphere Application Server environment. They are also used to specify application behavior that is vendor-specific, undefined in a current specification, or expected to be included in a future specification.
