c:choose and c:when tags aren't working....

Question

I have created a page that allows the user to change their password if they want. I am requiring they enter their current password and then the new password twice. When they click the submit button it will validate in the background that all passwords match and there are no mistakes... But if there are mistakes I want to set a variable to true then on my .jsp page use the <c:choose> and <c:when> tags to check if the variable is set to true and if it is have a message appear on the page saying it didnt work and to try again. Here's my code for the .jsp page:
            <c:choose>
                <c:when test="${ChangePasswordAction.showError == true}">
                    Your request to change your password was unsuccessful. Please try again!<br />
                </c:when>
                <c:otherwise>
                    Your request to change your password was successful. An email has been sent to your primary email address.<br />
                </c:otherwise>
            </c:choose>Any suggestions will help!! Thanks

Remember EL doesn't refer to java variables or classes. It uses the attributes in page, request, session and application scopes.
Is ChangePasswordAction an attribute in scope somewhere?
Does it have a "isShowError()" or "getShowError" method to reveal error as a boolean attribute?
