Hello, The bean-validation example works now, after adding jboss-logging-3.1.1.GA.jar
I didn't know I could use a jboss file jar with only Netbeans 7.3 and Apache Tomcat 7.0.34.So the java jar file influence the validation and the message errors directly on html page. PS : with the exclude_parameters example, the errors messages are not in the same files ======================================= exclude_parameters : EditAction.properties personBean.firstName=First name EditAction-validation.xml <validators> <validator type="requiredstring"> <param name="fieldname">personBean.firstName</param> <message>First name is required.</message> </validator> =================================== bean-validation ( All is in EditAction.properties ) EditAction.properties personBean.firstName=First name firstName.required=You must enter the first name=============================================== Regards, Chris
