JSP Unterminated Tag With Nested OGNL

Answer 1

Ah ok problem solved. Turns out the c:out wasn't needed to output the value of requestUri. It could simply be left as-is to be evaluated with the rest of the expression

Answer 2

You cannot use JSP tags in Struts tag's attributes, but you can use OGNL there.

Also note, that you can use OGNL only in Struts tag's attributes. And in most cases OGNL is executed once on the server, you shouldn't use nested OGNL or whatever you call it. May be this question will show you how to use you called nested OGNL.

<s:set var="requestUri" value="%{#context['com.opensymphony.xwork2.dispatcher.HttpServletRequest'].requestURI}" />
<s:a href="%{#action.userService.createLoginURL(#requestUri)}">Sign in</s:a>
