The JSP request is an implicit object of type HttpServletRequest i.e. created for each jsp request by the web container. It can be used to get request information such as parameter, header information, remote address, server name, server port, content type, character encoding etc.
The JSP request can be defined as an implicit object is an instance of "HttpServletRequest" and is formed for all JSP requests through the web container. This JSP request gets request information like a parameter, remote address, header information, server port, server name, character encoding, content type, etc.
getQueryString() – Used for getting the query string associated to the JSP page URL.
First get the PageContext by the inherited SimpleTagSupport#getJspContext() and then get the HttpServletRequest by PageContext#getRequest().
PageContext pageContext = (PageContext) getJspContext();
HttpServletRequest request = (HttpServletRequest) pageContext.getRequest();
