UnavailableException: Cannot load a validator resource from '/WEB-INF/ 1

[panugu]

Hi there,
Thanks for taking the time to read my post.

I am trying to configure struts validation to my application.

And I keep getting the following stack trace when I startup Weblogic (8.1 SP2). ----

UnavailableException: Cannot load a validator resource from '/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml'

Your help is really appreciated.

I am extending my action form with ValidatorForm as follows --

public class SubmitForm extends ValidatorForm {

}
============================================================

Here is part of my struts-config.xml

<struts-config>

<!-- ========== Form Bean Definitions ================= -->
<form-beans>

<form-bean name="submitForm" type="com.emergis.onlinereporting.struts.SubmitForm" />

</form-beans>

<!-- Global forwards -->
<global-forwards>
<forward name="error" path="/error.jsp" />
</global-forwards>

<!-- ========== Action Mapping Definitions ============ -->
<action-mappings>

<action path="/submitAction" type="com.emergis.onlinereporting.struts.action.SubmitAction"
name="submitForm"
input="/Submit.jsp"
scope="request"
validate="true">
<forward name="success" path="/DisplaySubmit.jsp" />
<forward name="failure" path="/Submit.jsp" />
</action>

</action-mappings>

<!-- message resources -->
<message-resources parameter="com.ApplicationResources" null="false" />
<!-- Validator plug-in-->
<plug-in className="org.apache.struts.validator.ValidatorPlugIn">
<set-property property="pathnames" value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml"/>
</plug-in>

</struts-config>

============================================================

Here is my validation.xml file --

<form-validation>

<!-- ========== Default Language Form Definitions ===================== -->
<formset>

<form name="submitForm">
<field property="lastName"
depends="required">
<arg0 key="validateform.lastname"/>
</field>
<field property="address"
depends="required">
<arg0 key="validateform.address"/>
</field>
<field property="sex"
depends="required">
<arg0 key="validateform.sex"/>
</field>
<field property="age"
depends="required">
<arg0 key="validateform.age"/>
</field>
</form>

</formset>

</form-validation>

============================================================

I am using Struts Version 1.2.4.

Struts DTD --

http://jakarta.apache.org/struts/dtds/struts-config_1_2.dtd

Validator DTD --

http://jakarta.apache.org/commons/dtds/validator_1_1_3.dtd

I found out that in validator.xml the list "arg" tags used to be arg0, arg1, arg2, or arg3. But it is replaced by

<arg position="0". But even after making this change, I still get the same error. Here is the change --

<form name="submitForm">
<field property="lastName"
depends="required">
<arg position="0" key="validateform.lastname"/>
</field>
<field property="address"
depends="required">
<arg position="0" key="validateform.address"/>
</field>
<field property="sex"
depends="required">
<arg position="0" key="validateform.sex"/>
</field>
<field property="age"
depends="required">
<arg position="0" key="validateform.age"/>
</field>
</form>

Not sure if I have a concrete answer for you, but I would look here:
<set-property property="pathnames" value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml"/>

To me, that error is saying it can't find it at all. I would fiddle with the /'s

but I just dug up on a few websites on google, the translation is bad, but there may also be a bug with accessing dtd's on the net from within your files?

An example being this:
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"

http://java.sun.com/j2ee/dtds/web-app_2_2.dtd";>

Thanks Andrew, I'll try if that will give me a positive result.

Thanks,

Any progress on your issue?

Sorry for not getting back sooner.

I tried every thing I could think of but did not work. I played with the <set-property> tag's. I installed latest version of validation jar file.

Finally, I gave up and I am still using the validating in my ActionForm class.
