Answer 1

You can get it by HttpServletRequest#getServletPath().

${pageContext.request.servletPath}

You can use the JSTL functions taglib to extract the extension whenever necessary.

it gives me something like /webinf/views/myPage.jsp , can you please give me a little help how to extract the name only – Dissected

Ah OK, you're using a controlling servlet which forwards to JSPs in /WEB-INF folder. Use ${requestScope['javax.servlet.forward.servlet_path']} instead to get the servlet path of the URL as it appears in browser address bar. – Underworld

i was able to do it in the following way too: request.getRequestURI().substring(request.getRequestURI().lastIndexOf("/")+1,request.getRequestURI().lastIndexOf(".")); – Dissected

Answer 2

To get the page:

<% String pageName = com.kireego.utils.Utils.extractPageNameFromURLString(request.getRequestURI()); %>

and this helper code:

public static String extractPageNameFromURLString(String urlString){
        if (urlString==null) return null;
        int lastSlash = urlString.lastIndexOf("/");
        //if (lastSlash==-1) lastSlash = 0;
        String pageAndExtensions = urlString.substring(lastSlash+1);
        int lastQuestion = pageAndExtensions.lastIndexOf("?");
        if (lastQuestion==-1) lastQuestion = pageAndExtensions.length();
        String result = pageAndExtensions.substring(0,lastQuestion);
        return result;
    }

This line will get you the correct JSP name, it's working also when the page includes multiple pages

<%= this.getClass().getSimpleName().replaceAll("_5F", "").replaceFirst("_", "") %>.jsp<BR>

Not working when invoked from a tag – Autonomy

@Autonomy need to be in the jsp body – Kalmick

Answer 4

maybe you can get it thought javascript way, like:

var url = window.location.href;

then use string methods to get current page name.
