Struts 1.3 pain

I am trying to convert a Struts 1.2 app to Struts 1.3.

Method definitions for custom validation in validator-rules.xml

Struts 1.2 Version

<validator name="required"
classname="org.apache.struts.validator.FieldChecks"
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"/>

Struts 1.3 Version

<validator name="required"
classname="org.apache.struts.validator.FieldChecks"
method="validateRequired"
methodParams="java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionMessages,
>>>>>>>>>org.apache.commons.validator.Validator,<<<<<<<<<
javax.servlet.http.HttpServletRequest"
msg="errors.required"/> 

 

In Struts 1.2 version I did not have to pass the Validator object for
the required field. But with 1.3 am being forced to do so, if not I get
a No Such Method Exception. Now that I have tweaked the "required"
validator, when I try to run my struts application, am getting a
org.apache.commons.validator.ValidatorException: No such validation
method: null exception. Digging into the error stack trace it says
java.lang.NullPointerException: No message resources found for bundle:
org.apache.struts.action.MESSAGE

I have the validator.xml, validator-rules.xml and errors.properties
intact from my Struts 1.2 version.

Any thoughts or ideas of what am doing wrong.

Harsh.

I will try that.
Thanks a lot for your input.

Well, there's no reason to put everything into one file. I had this same
problem (upgrading between commons-validator releases, and from Struts
1.2 to 1.3), and then I read that you can use more than one file.

Now, I have this in my struts-config.xml:

    <plug-in className="org.apache.struts.validator.ValidatorPlugIn">
        <set-property property="pathnames"
            value="/org/apache/struts/validator/validator-rules.xml,
            /WEB-INF/my-validator-rules.xml,
            ..." />
    </plug-in>

Note that you can use the stock validator-rules.xml file directly from
within the JAR file that it comes with.

Just add your own rules file after that. Then, at least, you only have
to update your own file (and source files as well) when you upgrade.

There is no specific reason, But we have one custom validation, So is it
good practice to revamp the entire the validator.xml file then?

Any other gotchas from someone who has migrated a 1.2 app to 1.3?

Is there a reason to keep your old validator.xml file? Why not just
overwrite the one you have with the new one?
