Configuring Web Application Deployment Descriptors
See Also
Deployment descriptors are XML-based text files whose elements
describe how to assemble and deploy a module to a specific environment.
The elements also contain behavioral information about components not included directly in code.
For web applications, there are three types of deployment descriptors:
- web.xml.
The general web application deployment descriptor that configures deployment settings
for components belonging to a web application,
such as servlets and JSP files.
- sun-web.xml.
The server-specific deployment descriptor that configures
deployment settings for the Sun Java System Application Server.
- context.xml.The server-specific deployment descriptor that configures
deployment settings for the Tomcat Web Server.
To edit web.xml:
- In the Projects window, expand the Configuration Files node for your web application project.
- Double-click web.xml to open it in the web.xml Visual Editor.
The web.xml Visual Editor opens in a Source Editor tab. The editor contains an Overview
section and a section for most of the elements in the web.xml file.
- Edit the deployment descriptor as necessary. See the following topics for more information:
- (Optional) Click XML at the top of the web.xml Visual Editor
to view and edit the deployment descripor's XML code.
- Choose File > Save to save your changes.
To edit sun-web.xml:
- In the Projects window, expand the Configuration Files node for your web
application project.
- Double-click sun-web.xml to open it in the graphical editor.
The graphical editor opens in a Source Editor tab. The editor contains a tree
view of the module's contents on the left and property editors for each item
on the right.
- Edit the deployment descriptor as necessary. See the following topics for
more information:
- Choose File > Save
to save your changes.
- If you enter any XML syntax errors the IDE automatically alerts you. To
fully ensure your changes have not cause any errors, you should verify the
web application.
To edit context.xml:
- In the Projects window, expand the Configuration Files node for your web application project.
- Double-click context.xml to open it in the graphical editor.
The graphical editor opens in a Source Editor tab. The editor contains a tree
view of the module's contents on the left and property editors for each item
on the right.
- Edit the deployment descriptor as necessary.
