R: validator NullPointer- please help

[daniele rizzi <da...@largesys.it>]

hi,
have you enclosed the jakarta regexp library?
(it's required by validator only, so everything else works
as usual)

bye, d.rizzi

Oggetto: validator NullPointer- please help



I am having problems installing the validator. I am getting a
NullPointerException (see below) in the validate method of
...commons.validator.Validator. I followed the install instructions and just
can't figure out what it causing the exception.

        at com.evermind[Orion/1.5.4 (build 10585)]._bt.run(.:62)

-----------------------------------------

My configuration is as follows.

1) /WEB-INF/struts-config.xml

<form-bean name="myForm" type="com.ponthrops.web.MyForm" /> (MyForm extends
ValidatorForm)

2) /WEB-INF/validation.xml

<form-validation>
   <global>
   </global>
   <formset>
      <form  name="myForm">
      <field property="firstName"
          indexedProperty="member"
          indexedListProperty="members"
          depends="required">
   <arg0 key="error.firstname.displayname"/>
      </field>
      </form>
   </formset>
</form-validation>


3) validator-rules.xml includes the validator "required"

4) /WEB-INF/lib includes commons-validator.jar, struts-validator.jar, and
jakarta-regexp-1.2.jar

5) web.xml includes the example servet config given in the install
directions

My guess is I missed a configuration step, however I can't seem to figure
out where.

Any help is greatly appreciated.



Thanks so much,

Petra

type="VariationBean[]">
   <html:select size="5" multiple="yes" property="Vvb.id.id" name="elements"
styleClass="formText">
    <html:options collection="elements" property="Vvb.id"
labelProperty="valueid"/>
    </html:select>
