This will re-direct the request and call the controller for the new URL. return new ModelAndView(“redirect:/myURL”); Alternatively you could take in the HttpServletResponse in your controller method and return a redirect. public void myController(HttpServletResponse response){ response.sendRedirect(“/myURL”); }
I prefer to avoid scriptlets in the middle of my page and was having to use them (increasingly often) to escape strings when used in JavaScript code. I wanted an Expression Language (EL) way of escaping the strings. I created a very small custom taglib that I use for just this purpose: Utilities.java: package com.mycom.taglibs; … Read more
I ran out of static html/jss/css blocks I could externalize into jsp:include (mostly non-static html was left) … You can put in your web.xml, mappedfile set to false like so to get rid of many static lines that aren’t necessarily good blocks to put into an include, but they add up to save space: <servlet> … Read more
