I want to retrieve root path of webapplication, then I want to append link to root path. I tried request.context but it returns \"http://localhost:8080/webapp/web-inf\".

You can also use
```
<c:url>
```
jstl tag. It will add the context path for you.

```
<%=request.getContextPath()%> 
```
will give you the rootpath of your application so in your case it will be http://localhost:8080/webapp

As per comment:
```
<%=request.getContextPath()%>/help/page/help.htm 
```
will give you your page

I believe you can use the getRealPath() method of the ServletContext.

You can use pageContext.request.contextPath

${pageContext.request.contextPath}

So you can use,

<a  href="${pageContext.request.contextPath}${helpPath}" target="_blank">name</a>

But the better way is to set the base href to this path and then use the path as it is.

<head>

        <base href="${pageContext.request.contextPath}">

    </head>
<body>
<a  href="${helpPath}" target="_blank">name</a>

</body>

<%=request.getContextPath()%> will give /webapp

So your link should look like :
```
<a  href="<%=request.getContextPath()%>${helpPath}" target="_blank">name</a>
```
