Subject [validator] Problems with method invokation for application validation
Date Mon, 20 Feb 2006 16:23:21 GMT
Im currently trying to use the Validator for my swing-application. Therefor
I modified a tutorial, so that those sources were created (shortened: no 
exception etc):

validation source:
        ValidatorResources resources = null;
        File f = new File("validation.xml");
        resources = new ValidatorResources(f.getAbsolutePath());

        Validator validator = new Validator(resources, "plugin1");
        Value v = new Value();
        validator.setParameter(Validator.BEAN_PARAM, v);

        ValidatorResults results = null;
        results = validator.validate();

The Object "Value" is only my data carrier with two String named 
textfield1 and
textfield2 with corresponding getters/setters.
the validation-xml shall only validate, that these fields are filled 
with values ("required"):

<!DOCTYPE form-validation PUBLIC
     "-//Apache Software Foundation//DTD Commons Validator Rules 
Configuration 1.1//EN"
     "http://jakarta.apache.org/commons/dtds/validator_1_1.dtd">

<form-validation>

    <global>
           <validator name="required"
                classname="org.apache.struts.util.StrutsValidator"
                method="validateRequired"
                methodParams="java.lang.Object,
                      org.apache.commons.validator.ValidatorAction,
                      org.apache.commons.validator.Field,
                      org.apache.struts.action.ActionErrors,
                      javax.servlet.http.HttpServletRequest"
            msg="errors.required">
        </validator>

    </global>
   
    <formset>
        <form name="plugin1">
            <field property="textfield1" depends="required">
                <arg0 key="login.textfield1"/>
            </field>
 
            <field property="textfield2" depends="required">
                <arg0 key="login.textfield2"/>
            </field>
        </form>
    </formset>
   
 </form-validation>


The problem is, that  I get an Exception at "results = 
validator.validate();" which is:
org.apache.commons.validator.ValidatorException: 
org.apache.struts.util.StrutsValidator
    at 
org.apache.commons.validator.ValidatorAction.loadValidationClass(ValidatorAction.java:623)
    at 
org.apache.commons.validator.ValidatorAction.executeValidationMethod(ValidatorAction.java:531)
    at org.apache.commons.validator.Field.validateForRule(Field.java:766)
    at org.apache.commons.validator.Field.validate(Field.java:845)
    at org.apache.commons.validator.Form.validate(Form.java:290)
    at org.apache.commons.validator.Validator.validate(Validator.java:353)
    at ValidatorTest.validate(ValidatorTest.java:55)
    at ValidatorTest.main(ValidatorTest.java:150)

I think my fault is to use the "methodParams" which are provided for web 
interfaces and jsp.
But how can i use the standard validators (like required) for my plain 
value object or single
values?
