I tried your tag and it works good!!
<c:out value="${formToValidate.firstName}" />
But how can I "c:out" a function. I get an error when
trying this:
<c:out
value="${formToValidate.getErrorMsg("firstName")}" />
error:
org.apache.jasper.JasperException:
/memberAddForm.jsp(8,53) equal symbol expected
thanks again
