Disabling Scripting

By default, scripting in JSP pages is valid. Since scripting can make pages difficult to maintain, some JSP page authors or page authoring groups may want to follow a methodology where scripting elements are not allowed.

You can invalidate scripting for a group of JSP pages by setting the scripting-invalid element of a JSP property group to true. For information on how to define a group of JSP pages, see Setting Properties for Groups of JSP Pages (page 685). When scripting is invalid, scriptlets, scripting expressions, and declarations will produce a translation error if present in any of the pages in the group. Table 19-1 summarizes the scripting settings and their meanings:
