java - CSS and JS are not rendered when index.jsp is set as welcome file -

i facing problem in jsp-servlet, when setting index.jsp welcome-file (default page run first project gets run) @ time css , js files not rendered. project hierarchy this

-projectname
        -user
             -css
             -js
             -index.jsp

and when run project url in browser localhost:8080/projectname here index.jsp called without css , js files.

edit: finally, had solved issue copying css , js root directory also. i.e. have css , js @ "user" "projectname".

try context path,

<link href="${pagecontext.request.contextpath}/css/style.css" rel="stylesheet" type="text/css">  

will path of css file in css folder. or scriptlet,

<link rel="stylesheet" type="text/css" href="<%=request.getcontextpath() %>/css/style.css"> 

however, not recommended use scriptlets in jsp.
