Get Context Path from JSP Using No Java Code

Hi all,

What's a better way to get context path in view (JSP)? We know we can use request.getContextPath() but putting Java code in view is not recommended so is there a tag available to perform that task?

Thanks.

If you use the Struts html:xxx tags, you don't have to worry about the context path because Struts automatically includes it. Example:

translates the link to:
/myapp/jsp/mpage.jsp

You can also generate a URL variable that includes the context path using the c:url tag. Once you have the URL in a variable, you can then reference it with a c

ut tag.

Thanks Merrill.

Output of <s:url value="/..."/> is also prefixed by context path.

The problem with <s:url .../> is request parameters are also appended to the output. Here is the detail:

Action: LoginAction.java
The result (view) of the action is login.jsp
In login.jsp, there is one line code: <s:url value="/css/mycss.css"/>

Source of the page generated by .../LoginAction.action?lang=en is:
/<context path>/css/mycss.css?lang=en

Could anyone explain why? How to let output not include ?lang=en

Thanks.

Try this:

Hi,Can any tell me which tag lib is used.I mean what 's' is in <s:url> tag.thanks

That thread's over a year old... :/

The "s" prefix is normally used for the Struts 2 taglib.

yeah,i know that the thread is very old.I am also facing similiar problem.

the problem: In the login page i try to include the css file which is not in the same directory as the login.jsp(It is direct under the root directory of the application).so in the jsp i put css inclusion as below:

<link rel="stylesheet" type="text/css" href="/resources/mycss.css"/>

It is not included.but when i move the mycss.css file to the root directory of the application,i see the styles applied on the page.I dont wont to use a scriptlet . liek the stuff like this in the login.jsp

<% String contextPath = request.getContextPath();%>

<link rel="stylesheet" type="text/css" href="${contextPath}/resources/mycss.css"/>

Could you help in this please

First off, I believe you could just use ${request.contextPath}. The tag-based way to do it would be to construct a URL: <link rel... type... href="<s:url value="/"/>/resources/mycss.css"/> (or use JSTL; really doesn't matter in this case I think).

${pageContext.request.contextPath}

Yeah, that :)

thanks all for replies and time.
