Runtime Configuration of Web Modules 

Use

You can view and configure the settings of your Web modules that are deployed at runtime. These settings are contained in the deployment descriptors of the Web modules (web.xml and web-j2ee-engine.xml).

You can change most of the settings for a Web module and the individual Web components included in it (such as servlets, JSP pages, or filters). However, a few restrictions apply:

●      No functions are provided for adding or deleting a file in the Web application. To add or delete a file, you can use the Single File Update function described in Updating a Single File.

●      You cannot change the security settings in the Web applications that are deployed, you can only view them. If you need to change the security strategy for your Web application, you have to redeploy it.

●      You cannot save any changes to the following default servlets loaded from the Global Web Descriptor for each Web module: jsp, PutServlet, ChangePasswordForm, invoker, and default.

●      You cannot change any of the display settings for the Web module as a whole, or for individual servlets, JSP pages or filters.

Features

Using the Web Modules editor, you can configure (or view) the following settings of the Web modules:

●      Individual components’ settings

●      Welcome pages, error pages, MIME types, and response status codes

●      Servlet and filter mappings

●      References

●      Cookies configuration

●      General Web module’s context-related settings

Activities

You can display an overview of all Web modules that are deployed if you choose System Management → Configuration → Application Modules. To display the Web modules only, you must choose Web Modules from the Show dropdown list box in the Application Modules frame.

After changing settings of any of the application modules, you need to choose Save to apply your changes.

You can open the configuration settings for the application (contained in the application.xml and application-j2ee-engine.xml descriptors) that the application module you selected is part of. To do this, choose Application Details. In the new editor you can adjust the configuration settings for this application.
