Re: [s2] use remoteUser with struts tags
Hello
I disable el because '#' is used by the JSP EL under JSP 2.1 and I use this
character in OGNL expressions. This information is from
http://struts.apache.org/2.x/docs/ognl.html.
OK, disable is wrong word, I should wrote that I set isELignored to true :-)
My first idea was that I can use:
<s:property value="%{#request.getRemoteUser()}" />
or <s:property value="%{#request.isUserInRole('role_name')}" />
but this doesn't work.
I tried too:
<s:property value="%{@ServletActionContext.@getRequest().getRemoteUser()}"
/>
<s:property value="%{getRemoteUser()}" />
I don't have any errors, but result is null.
I'm sure that remoteUser is set, because I have <%= request.getRemoteUser()
%> in my jsp and I see good result ;-)
For <s:property value="%{request.getRemoteUser()}" /> I have error:
12:25:23:085 WARN com.opensymphony.xwork2.util.OgnlValueStack
[http-8080-Processor24]; Caught an exception while evaluating expression
'request.getRemoteUser()' against value stack
java.lang.NullPointerException: target is null for method getRemoteUser

Works:
%{@org.apache.struts2.ServletActionContext@getRequest().getRemoteUser()}

Does %{#request.remoteUser} work?
No, it doesn't work (result null).
It works when I set attribute remoteUser in request. This is
request.getAttribute("remoteUser"), no request.getRemoteUser().
