By default, scripting in JSP pages is valid. Because scripting can make pages difficult to maintain, some JSP page authors or page authoring groups may want to follow a methodology in which scripting elements are not allowed.
You can disable scripting for a group of JSP pages in an application in one of two ways:
Select the Ignore Java Script check box in the JSP Property Group node of the NetBeans IDE web.xml editor.
Set the scripting-invalid element of the application’s deployment descriptor to true. The scripting-invalid element is a child of the jsp-property-group element that defines properties for a set of JSP pages.
For information on how to define a group of JSP pages, see Setting Properties for Groups of JSP Pages. When scripting is invalid, it means that scriptlets, scripting expressions, and declarations will produce a translation error if present in any of the pages in the group. Table 9–1 summarizes the scripting settings and their meanings.
