Validator
I am trying to use Struts validator and am running into some problems. Are
there any good step-by-step instructions? I have Struts in Action and
tried to follow the chapter concerning Validator but I didn't get the
desired results and am not sure where to begin in tracing what I may have
done wrong or not done that I should have.
Thank you

calling previous ActionForm
Posted by Fedor Smirnoff <in...@olnix.com>.
Hi,
I need to access a method within an ActionForm that was used by the
Action that send a redirect to my current action.
So Action A using ActionForm A and after done processing redirects to
Action B that uses ActionForm B, question how can Action B access
ActionForm A
Thank you
Fedor

**Use the struts-validator.war example
in the struts 1.1 release to learn more.**
make sure you have this in your jsp:
<html:errors />
This is where the validation error gets outputted.
You should have this in your struts-config at the bottom where plug-ins go.
<!--
Add multiple validator resource files by setting the pathnames property
with a comma delimitted list of resource files to load.
-->
<plug-in className="org.apache.struts.validator.ValidatorPlugIn">
<set-property property="pathnames" value="/WEB-INF/validator-rules.xml,
/WEB-INF/validation.xml"/>
</plug-in>
You should not have to change validator-rules.xml most of the generic
validation is here.
You need to add your forms to validation.xml here is an example:
<form-validation>
<global>
<constant>
<constant-name>phone</constant-name>
<constant-value>^\(?(\d{3})\)?[-| ]?(\d{3})[-| ]?(\d{4})$</constant-value>
</constant>
<constant>
<constant-name>zip</constant-name>
<constant-value>^\d{5}\d*$</constant-value>
</constant>
</global>
<formset>
<constant>
<constant-name>zip</constant-name>
<constant-value>^\d{5}(-\d{4})?$</constant-value>
</constant>
<form name="userForm">
<field property="email"
depends="required,email">
<arg0 key="userForm.email.displayname"/>
</field>
<field property="firstname"
depends="required,mask,minlength">
<arg0 key="userForm.firstname.displayname"/>
<arg1 name="minlength" key="${var:minlength}" resource="false"/>
<var>
<var-name>mask</var-name>
<var-value>^\w+$</var-value>
</var>
<var>
<var-name>minlength</var-name>
<var-value>3</var-value>
</var>
</field>
<field property="lastname"
depends="required,mask,maxlength">
<arg0 key="userForm.lastname.displayname"/>
<arg1 name="maxlength" key="${var:maxlength}" resource="false"/>
<var>
<var-name>mask</var-name>
<var-value>^[a-zA-Z]*$</var-value>
</var>
<var>
<var-name>maxlength</var-name>
<var-value>10</var-value>
</var>
</field>
<field property="address1"
depends="required">
<arg0 key="userForm.address1.displayname"/>
</field>
<field property="city"
depends="required,mask">
<arg0 key="userForm.city.displayname"/>
<var>
<var-name>mask</var-name>
<var-value>^[a-zA-Z\s]*$</var-value>
</var>
</field>
<field property="state"
depends="required,mask">
<arg0 key="userForm.state.displayname"/>
<var>
<var-name>mask</var-name>
<var-value>^[a-zA-Z]*$</var-value>
</var>
</field>
<field property="zip"
depends="required,mask">
<arg0 key="userForm.zip.displayname"/>
<var>
<var-name>mask</var-name>
<var-value>${zip}</var-value>
</var>
</field>
<field property="phone"
depends="required,mask">
<arg0 key="userForm.phone.displayname"/>
<var>
<var-name>mask</var-name>
<var-value>${phone}</var-value>
</var>
</field>
<field property="password"
depends="required,password">
<arg0 key="userForm.password.displayname"/>
</field>
</form>
<form name="userPasswordForm">
<field property="email"
depends="required,email">
<arg0 key="userForm.email.displayname"/>
</field>
<field property="distance"
depends="required,integer">
<arg0 key="teacherForm.distance.displayname"/>
</field>
<field property="rate"
depends="required,float">
<arg0 key="teacherForm.rate.displayname"/>
</field>
</form>
</formset>
</form-validation>
(both the validator-rules.xml and validation.xml go in your Web-inf
directory
If you are using forms extend ValidatorForm
If you are using DynaValidatorForm use this in your form definitions in your
struts-config
type="org.apache.struts.validator.DynaValidatorForm"
In your validation.xml you have this:
<arg0 key="teacherForm.children_experience.displayname"/>
this key is used in your message resource.
This goes in your message resource file:
errors.header=<font color="#FFF000" face="Arial, Helvetica, sans-serif">You
must complete the following information before proceeding:<ul>
header will be displayed first.
The <arg0 key="teacherForm.children_experience.displayname"/>
will be the {0} in the resource file.
These also goes in your message resource file (whatever you require):
errors.minlength=<li>{0} cannot be less than {1} characters.</li>
errors.maxlength=<li>{0} cannot be greater than {1} characters.</li>
errors.email=<li>{0} is an invalid e-mail address.</li>
errors.required=<li>{0} is required.</li>
errors.invalid=<li>{0} is invalid.</li>
errors.float=<li>{0} must be a decimal number.</li>
errors.integer=<li>{0} must be a number.</li>
errors.footer=</ul></footer</li>
Typically when I get an error (nothing happenns) it is because I had a typo
in the
validation.xml file.
I learned validation by looking at the struts-validator.war in the 1.1
Release
Hope this helps.
Barry
