Error with Spring Modules Commons Validator

mons.DefaultValidatorFactoryquot;gt;
lt;property name=quot;validationConfigLocationsquot;gt;
lt;listgt;
lt;valuegt;/WEB-INF/validator-rules.xmllt;/valuegt;
lt;valuegt;/WEB-INF/validation.xmllt;/valuegt;
lt;/listgt;
lt;/propertygt;
lt;/beangt;

lt;bean id=quot;beanValidatorquot; class=quot;org.springmodules.validation.commons.DefaultBeanValidatorquot;gt;
lt;property name=quot;validatorFactoryquot; ref=quot;validatorFactoryquot;/gt;
lt;/beangt;
and I've modified my validation-rules.xml file to have:Code:
lt;validator name=quot;requiredquot; classname=quot;org.springmodules.validation.commons.FieldChecksquot; method=quot;validateRequiredquot; methodParams=quot;java.lang.Object, org.apache.commons.validator.ValidatorAction, org.apache.commons.validator.Field, org..validation.Errorsquot; msg=quot;errors.requiredquot;gt;
lt;javascriptgt;lt;![CDATA[
(...) ]]gt;lt;/javascriptgt;
lt;/validatorgt;

lt;validator name=quot;requiredifquot; classname=quot;org.springmodules.validation.commons.FieldChecksquot; method=quot;validateRequiredIfquot; methodParams=quot;java.lang.Object, org.apache.commons.validator.ValidatorAction, org.apache.commons.validator.Field, org..validation.Errors, org.apache.commons.validator.Validatorquot; msg=quot;errors.requiredquot;gt;
lt;/validatorgt;
but I'm getting this error when starting the app:Code:

Could someone explain what the NullPointerException is referring to?? Is it a field in my input form???

Your configuration seems to be correct. can you reproduce this exception within a test?

Well, I finally resolved this problem. What it turned out to be was that I was using an incompatible version of validation-rules.xml file. When I upgraded to Struts 1.2.9, I failed to replace this file also. Once I did that, everything started to work.

ok cool... happy to hear everything worked out

I have problem, when i use requiredif It doesn't work. can u please help me. thank u
