Not sure what you mean by "standalone" and "with Struts". Are you using the standard built-in Struts validation? From the error below I guess not - I can only see one way this could have happened: 1) A "null" reference was passed to the validateMask() method where it expected an "ActionMessages" object. 2) The "null" ActionMessages caused a "NullPointerException" to be thrown on line 235 of FieldChecks in the validateMask() method (where it tries to add a message to the ActionMessages object). 3) That NullPointerException was caught by the try/catch block in the validateMask() method so it called the processFailure() method. 4) The processFailure() method logged the message "mask validation failed for property xpto: java.lang.NullPointerException" 5) The processFailure() threw another NullPointerException on line 1323 when it tried to add a message to ActionMessages 6) ValidatorAction caught the 2nd NullPointerException and logged the message "Unhandled exception thrown during validation: null" + stack trace Perhaps I'm wrong, but this is the only explanation I can see. If I am right then it looks like you are not using the standard build-in Struts validation and the problem is you haven't configured the "Validator" instance you're using with an ActionMessages object. Fixing that issue should resolve the problem - something like: validator.setParameter(ACTION_MESSAGES_PARAM, errors); Best place to look on initializing Validator is in the validate() method of ValidatorForm[1] and initValidator() method of Resources[2] [1] http://svn.apache.org/repos/asf/struts/struts1/trunk/core/src/main/java/org/apache/struts/validator/ValidatorForm.java [2] http://svn.apache.org/repos/asf/struts/struts1/trunk/core/src/main/java/org/apache/struts/validator/Resources.java Niall > Since using new versions 1.3.1 (commons-validator) and 1.3.9 (struts), > an error occurred. > > > [WARN ][2007-11-09 > 16:43:17,039][org.apache.struts.util.PropertyMessageResources]: > Resource org/apache/struts/validator/LocalStrings_en_GB.properties Not > Found. > [WARN ][2007-11-09 > 16:43:17,039][org.apache.struts.util.PropertyMessageResources]: > Resource org/apache/struts/validator/LocalStrings_en.properties Not Found. > [ERROR][2007-11-09 > 16:43:17,041][org.apache.struts.validator.FieldChecks]: mask validation > failed for property xpto: java.lang.NullPointerException > [ERROR][2007-11-09 > 16:43:17,043][org.apache.commons.validator.ValidatorAction]: Unhandled > exception thrown during validation: null > java.lang.NullPointerException > at > org.apache.struts.validator.FieldChecks.processFailure(FieldChecks.java:1323) > at > org.apache.struts.validator.FieldChecks.validateMask(FieldChecks.java:243) > > > Any ideia? --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
