org.springframework.web.servlet.support.RequestContext

org.springframework.web.servlet.support.JspAwareRequestContext

public class JspAwareRequestContext
extends RequestContext

JSP-aware (and JSTL-aware) subclass of RequestContext, allowing for population of the context from a javax.servlet.jsp.PageContext.

This context will detect a JSTL locale attribute in page/request/session/application scope, in addition to the fallback locale strategy provided by the base class.

1.1.4
