public class EscapeBodyTag
extends HtmlEscapingAwareTag

Custom JSP tag to escape its enclosed body content, applying HTML escaping and/or JavaScript escaping.

Provides a "htmlEscape" property for explicitly specifying whether to apply HTML escaping. If not set, a page-level default (e.g. from the HtmlEscapeTag) or an application-wide default (the "defaultHtmlEscape" context-param in web.xml) is used.

Provides a "javaScriptEscape" property for specifying whether to apply JavaScript escaping. Can be combined with HTML escaping or used standalone.
