Request object is not passed to static method using OGNL in struts2

Question

I am developing a Struts 2.3 application. In that application I am calling a static utility method from JSP which takes HttpServletRequest object as argument and returns a string after processing request. When I tried using JSP scriptlet, method got invoked with proper argument like:

<%
    String resultStr = com.testapp.util.Utility.getResult(request);
%> 

But when I tried to use the OGNL for the same logic, method got invoked with null request object as argument instead of actual request object like:

<s:set name="resultStr" var="resultStr"
       value="@com.testapp.util.Utility@getResult(request)" /> 

I also tried #request instead of request in OGNL but in that case method didn't get invoked.

Answer 1

Put this constant in the configuration file to enable static method access.

<constant name="struts.ognl.allowStaticMethodAccess" value="true" />

Use

<s:set name="resultStr" var="resultStr" value="@com.testapp.util.Utility@getResult()" /> 

and in the getResult() {

HttpServletRequest request = ServletActionContext.getRequest();
