Struts 1.2.7 Validation blues

[Jan van Doorn]

Hello,

I have wasted many hours on trying to solve this one:

- working with struts 1.2.7, Resin 3.0.14, jdk1.4.

Want to implement Struts validation using validation.xml.

I have a simple Loginform with 2 fields (LoginForm.java), registered in struts-config.xml:

<form-bean name="LoginForm" type="nl.upi.workmate.struts.umba.LoginForm" >
<form-property name="userId" type="java.lang.String" />
<form-property name="passWord" type="java.lang.String" />
</form-bean>

� and corresponding action:

<action
path="/loginDemo"
type="nl.upi.workmate.struts.umba.LoginAction"
name="LoginForm"
input="/jsp/LoginView.jsp"
validate="true">
<forward name="valid" path="/jsp/MainMenu.jsp" />
<forward name="invalid" path="/jsp/LoginView.jsp" />
</action>


I defined the plugin in struts-config.xml:

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


Then why does it not work ??!!
BTW: it does work under Struts 1.1.

When I press submit in the Loginform I get this in the Resin-console:

[22:05:26.256] Server[] starting

[alan do]

ActionErrors/ActionError are deprecated since 1.2.x. it looks like you may have validator-rules.xml file (old) that is still defining validator rules using these classes. change these to ActionMessages/ActionMessage instead.

Problem solved !

Reason: there were no corresponding error messages in the Resource file.

<validator name="required"
classname="org.apache.struts.validator.FieldChecks"
method="validateRequired"

Looking at an entry in validator-rules.xml:

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"/>

... I now understand the exception.

The error was caused because I had no entry for errors.required
