 Posted: Sun Apr 01, 2007 3:01 pm Post subject: Struts 1.2 validation not working! |
 |
|
I've added Struts validation to my application and I'm getting an exception when I try to use the 'required' validation type.
My app is created using the MyEclipse IDE, which I believe uses Struts 1.2. Separately I downloaded an archived copy of Struts 1.2.7 and compared the MyEclipse 'validator-rules.xml' file the r1.2.7 version and they are both the same.
Here's the code...
The 'validation.xml' file...
| Code: |
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE form-validation PUBLIC "-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.1.3//EN" "http://jakarta.apache.org/commons/dtds/validator_1_1_3.dtd">
<form-validation>
<formset>
<form name="impactNegationEditForm">
<field property="title" depends="required">
<arg0 key="label.title"/>
</field>
</form>
</formset>
</form-validation>
|
the start of the 'validation-rules.xml' file...
| Code: |
<!DOCTYPE form-validation PUBLIC
"-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.1.3//EN"
"http://jakarta.apache.org/commons/dtds/validator_1_1_3.dtd">
<form-validation>
<global>
<validator name="required"
classname="org.apache.struts.validator.FieldChecks"
method="validateRequired"
methodParams="java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionMessages,
org.apache.commons.validator.Validator,
javax.servlet.http.HttpServletRequest"
msg="errors.required"/>

the related action class...
| Code: |
public class ImpactNegationEditAction extends AbstractImpactNegationAction
implements EntityIDs, ImpactNegationIDs {
public void save_onClick(FormActionContext aCtx) {
ImpactNegationEditForm aForm = (ImpactNegationEditForm) aCtx.form();
aCtx.addErrors(aForm.validate(aCtx.mapping(),aCtx.request()));
if (aCtx.hasErrors() == false) {
// is add?
if (aForm.getImpactNegationIDInt() == ID_UNASSIGNED) {
// verify title is unique
try {
ImpactNegation anOther = getManager(aCtx).findByTitle(aForm.getTitle());
if (anOther != null) {
addFieldError(aCtx,"title","error.duplicateField","Title");
}

the related form...
| Code: |
public abstract class AbstractSorForm extends FWValidatorForm {
}
public class ImpactNegationEditForm extends AbstractSorForm {
private static final long serialVersionUID = 3604637580339030809L;
private String fImpactNegationID;
private String fTitle;
private String fDesc;
private String fDisplayOrder;
private String fPercent;
private String fCaptionDetail = null;
private String fFormTitle = null;
public ImpactNegationEditForm() {
// TODO Auto-generated constructor stub
}
public String getDesc() {

public void setDesc(String aDesc) {
fDesc = aDesc;
}
public String getDisplayOrder() {
return fDisplayOrder;
}
public int getDisplayOrderInt() {
return Integer.parseInt(fDisplayOrder);
}
public void setDisplayOrder(String aDisplayOrder) {
fDisplayOrder = aDisplayOrder;
}
public String getImpactNegationID() {
return fImpactNegationID;
}
public int getImpactNegationIDInt() {
return Integer.parseInt(fImpactNegationID);
}
public void setImpactNegationID(String aId) {
fImpactNegationID = aId;
}
public String getPercent() {
return fPercent;
}
public double getPercentDouble() {
return Double.parseDouble(fPercent);
}
public void setPercent(String aPercent) {
fPercent = aPercent;

public String getTitle() {
return fTitle;

}
public String getFormTitle() {
return fFormTitle;
}
public void setFormTitle(String aFormTitle) {

}
}

the JSP body file...
| Code: |
<ctrl:headline caption="Impact Negation" detail="${impactNegationEditForm.captionDetail}" width="60%"/>
<html:form action="sor/admin/impact_negation/impact_negation_edit" >
