EL expression ${pageContext.request}

[Colin Shine]

The EL expression

${pageContext.request}

returns a

 ServletRequest 

, not a

 HttpServletRequest 

.

This is a problem for me, because I want to prepend each 'src' attribute of my image tags with the application context path, i.e.

<img src="${pageContext.request.contextPath}/images/myimage.gif" />

There is no getContextPath() in

 ServletRequest 

! Is there a way around this without some ugly hack like placing the context path as a context init param, so it's accessible through EL like:

 ${initParam.myContextPath} 

:roll:

<img src="${pageContext.request.contextPath}/images/myimage.gif" />

Works for me.
What container are you using?

Hi Ben,

Thanks for the quick reply! I'm using Tomcat 5.5.12.

I just tried with 5.5.9 and
Context Path: ${pageContext.request.contextPath}
printed
Context Path: /SimpleServlet

Ah, I've got it to work!

The problem was I was using these images on my login page, and since they were under a secure directory, Tomcat wasn't serving them until I was logged in.

When it wasn't working, I checked the spec and jumped to the wrong conclusion... :roll:
