If you have static methods turned on for OGNL, you might be able to use the
following expression -
@com.opensymphony.xwork2.actioncont...@getcontext().get(@org.apache.struts2.strutsstat...@http_request).getRemoteUser()
It's ugly, but it should work. Another thing to try is to whip up a quick
interceptor that pushes the String you want onto the value stack... Something
like the following should work -
ActionContext context = ActionContext.getContext();
context.getValueStack().set(
"remoteUser",
((HttpServletRequest)(context.get(HTTP_REQUEST))).getRemoteUser());
Then, any action that is intercepted by this interceptor could have a tag -
<s:property value="#remoteUser"/>
Of course, EL is fine too...
Struts doesn't expose many Servlet Spec objects as a design choice. There are
obviously times when it's necessary. Given adequate time, you might be able to
move away from the Serlvet Spec by incorporating something like Spring
Security, etc. But, that may not be practical, so stick with EL if you want
the quick solution, or write an interceptor if you want to make the solution
more Struts-y, and if you have enough time and want to gain a whole heck of a
lot of functionality, then try out Spring Security.
