How to implement alternate error messages in the Struts validation framework. (Struts 2.0.1.4)

[joann luo]

Hello,

I am currently using the Struts2 validation framework for my project.  I
have Struts 2.0.14.   I have been trying to find a way to display alternate
error message through validator framework.

I tried two things.



   1. I added a bundle attribute in the following code in the web.xml but
   that did not work.  The com.mytest.strings bundle is located in the
   WEB-INF\classes folder.



<field property="attribute(Number)"
depends="required,mask,maxbytelength,nonce">

<msg name="required" *bundle=”com.mytest.strings      *

”key="errors.required" />
  2.       Based on the following information from Programming Jakarta
Struts Chapter 11 The Validator Framework
http://books.google.com/books?id=E874l0jaUGQC&pg=PA260&lpg=PA260&dq=change+the+key+values+in+the+validation-rules.xml+if+you+plan+to+use+alternative+messages&source=bl&ots=t5zzY8fSs4&sig=wEOspEiq8XsU2su4yD1WlCz8H6w&hl=en&sa=X&ei=8_ZLT6TOHoPi0QGB4YiTDg&ved=0CCIQ6AEwAA#v=onepage&q=change%20the%20key%20values%20in%20the%20validation-rules.xml%20if%20you%20plan%20to%20use%20alternative%20messages&f=false




*“You should add these to your application’s resource bundle, or change the
key values in the validation-rules.xml if you plan to use alternative
messages.”*



I have the following code in validator-rules.xml file.



<validator   name="required"

            classname="StrutsValidators"

               method="validateRequired"

         methodParams="java.lang.Object,

                       org.apache.commons.validator.ValidatorAction,

                       org.apache.commons.validator.Field,

                       org.apache.struts.action.ActionMessages,

                       javax.servlet.http.HttpServletRequest"

                  msg="errors.required.new"/>



            <validator   name="mask"

            classname=" StrutsValidators"

               method="validateMask"

         methodParams="java.lang.Object,

                       org.apache.commons.validator.ValidatorAction,

                       org.apache.commons.validator.Field,

                       org.apache.struts.action.ActionMessages,

                       javax.servlet.http.HttpServletRequest"

              depends=""

                  msg="errors.invalid.new"/>





I added the following string to a separate bundle but with the same
properties file name. That bundle is located in a different directory.    I
updated the values of these two entries in this new properties file.



errors.required.new={0} is required NEW.

errors.invalid.new={0} is not valid NEW.





My validation.xml file looks like this:



<field property="attribute(Number)"
depends="required,mask,maxbytelength,nonce">

<msg name="required" key="errors.required" />

<msg name="maxbytelength" key="errors.maxlength" />

<var>

<var-name>maxbytelength</var-name>

<var-value>32</var-value>

</var>

<var>

<var-name>form</var-name>

<var-value>Info</var-value>

</var>

<msg name="mask" key="errors.invalid" />

<arg0 key="label.Number" />

<var>

<var-name>mask</var-name>

<var-value>^[0-9\-() ]*$</var-value>

</var>

</field>



When I ran my test I still see the standard error messages such as the ones
listed below displayed on the UI.  It appears that the validation framework
still reads from the default bundle.  However, all other labels on the same
UI can read from the customized properties file.

errors.required.new={0} is required.

errors.invalid.new={0} is not valid.



Is this a Struts issue?  If not, what is the right way to implement
alternate validation message in this case?



Thanks a lot.
