catching invalid variable references (jsp + struts)

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 ?



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,






For clean approach:

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 .
