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

[Ajay Reddy]

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>

"AJ",

Welcome to JavaRanch. We don't have many rules here, but we do have a naming policy which we strictly enforce. Pleaes re-read this policy and adjust your display name to comply. Thanks in advance and we look forward to seeing you around the Ranch.

[Ajay Reddy]

Sorry about that. Did not read the naming policy.

Are the files "validator-rules.xml" and "validation.xml" present in the WEB-INF folder of your web app?

[Ajay Reddy]

Yes, the validation.xml and validation-rules.xml are in WEB_INF directory of my web app.

Heh..."WEB_INF" or "WEB-INF"? Hope your problem is simply a path typo.

[Ajay Reddy]

Sorry, I have it as WEB-INF (just typo replying to the post). I can go to the jsp page (i.e. Submit.jsp) but when I click on the submit button I get
the error ---

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

Which is same as the one I get when I startup Weblogic.

Thanks once again.

[Sheldon Fernandes]

I wonder if its a problem with the DTDs. The ValidatorResources class tries to register these DTDs.

  
    private static final String registrations[] = {
        "-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.0//EN",
        "/org/apache/commons/validator/resources/validator_1_0.dtd",
        "-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.0.1//EN",
        "/org/apache/commons/validator/resources/validator_1_0_1.dtd",
        "-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.1//EN",
        "/org/apache/commons/validator/resources/validator_1_1.dtd",
        "-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.2.0//EN",
        "/org/apache/commons/validator/resources/validator_1_2_0.dtd"
    };

To verify if this could be the problem, trying commenting/removing the DOCTYPE declaration from both the xml files.

Just a guess. Worth trying I feel.

EDIT: Making the assumption that the xml files are valid and well-formed.
