I have a web app, where I have different navigation anchor tags such as Home, Profile and etc.
What I want:
When I press anchor tags like home or profile. I just want to ensure that current user gets its information in that Tags/JSP Page.
Sample Example that I am trying:
<a href="${pageContext.request.contextPath}/JSPAddress.jsp">Profile</a>
The
pageContextis an implicit object available in JSPs. The EL documentation saysThus this expression will get the current
HttpServletRequestobject and get the context path for the current request and append/JSPAddress.jspto it to create a link (that will work even if the context-path this resource is accessed at changes).The primary purpose of this expression would be to keep your links ‘relative’ to the application context and insulate them from changes to the application path.
For example, if your JSP (named
thisJSP.jsp) is accessed athttp://myhost.com/myWebApp/thisJSP.jsp, thecontext path will bemyWebApp. Thus, the link href generated will be/myWebApp/JSPAddress.jsp.If someday, you decide to deploy the JSP on another server with the context-path of
corpWebApp, the href generated for the link will automatically change to/corpWebApp/JSPAddress.jspwithout any work on your part.
