Disabling Scripting - The J2EE 1.4 Tutorial

Disabling Scripting

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 by using deploytool and setting the value of the Scripting Invalid checkbox in the JSP Properties tab of a WAR. 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 16-1 summarizes the scripting settings and their meanings.
