catching invalid variable references (jsp + struts)

[Csaba Szegedi]

Hello,

We are using JSP with Struts 1.2 and we had an invalid variable reference in the jsp page.
My question is: is there any chance to catch it later in the log or in any other else way ?

class Utils {
  private static int STATE = 0;
}
... PAGE
<%@ page import="com.mycomp.Utils" %>
...
<c:if test="${foo!=Utils.STATE}">

Thanks in advance.

you cant access static variable using class name in EL. EL only evaluate methods of a bean via setters/getters .

So, work around would be create a setter/getter instance method for the static variable then create a instance for that class and put it request/session scope and access that as in,

class Utils {  
  private static int STATE = 0;  
  //create setter/getter
  public String getSTATE(){
      return STATE;
  }
}  

<c:if test="${requestScope['utilInstance'].STATE}">

My question was about catching this kind error.

Oh, sorry . EL will not report error if the *Utils* property not found in any one of the scope.
So, I think you cant deal with such idiom .
