Hi all,

i have a JSP page in which im having one navigation bar created using JavaScript and DHTML.
all the javascript coding is done in seprate javascript file which i load in jsp using script tag

Now if i invoke that JSP directly from tomcat. Everything works fine Navigation bar is shown .

Now if i use RequestDispatcher from a servlet to call that JSP page Navigation Bar does not appear there is no script error.

I have checked this problem is occuring only when i use request dispatcher to call JSp Page . if i use send redirect then it works fine but if i use requestdispatch it does not work javascript file does not get loaded.

If its green its biology if its stinkks its chemistry if it has numbers it is Maths and if it doesn't work its TECHNOLOGY

Sounds like a URL path problem to me... what's the URL you're using to load the javascript file in the JSP?

If you're using a relative path, calling the JSP using RequestDispatcher will attempt to make the URL relative to the original caller (the servlet's) URL. If you send a redirect it makes the browser make a completely new request, so the relative URL will find the javascript file. Specify the full URL to the javascript file to fix this.
