Setting Initialization Parameters

The web components in a web module share an object that represents their application context (see Accessing the Web Context). You can pass initialization parameters to the context or to a web component.

    To add a context parameter using NetBeans IDE, do the following:

  1. Open the project if you haven’t already.

  2. Expand the project’s node in the Projects pane.

  3. Expand the Web Pages node and then the WEB-INF node.

  4. Double-click web.xml.

  5. Click General at the top of the editor pane.

  6. Select the Context Parameters node.

  7. Click Add.

  8. In the Add Context Parameter dialog, do the following:

    1. Enter the name that specifies the context object in the Param Name field.

    2. Enter the parameter to pass to the context object in the Param Value field.

    3. Click OK.

Alternatively, you can edit the XML of the web.xml file directly by clicking XML at the top of the editor pane and using the following elements to add a context parameter:

For a sample context parameter, see the example discussed in The Example JSP Pages.
