Hi,
I have developed simple GWT application which conatian
firsrname,lastname, birthYear
field.
Now I am trying to add validation for birthYear field .
I have added
1) gwt-validation-1[1].0.jar
2)gwt-vl-hibernate-0.5b.jar
in classpath of environment variable.
my application code are:
MyApplication.gwt.xml
<module>
<!-- Inherit the core Web Toolkit stuff. -->
<inherits name='com.google.gwt.user.User'/>
<inherits name='com.google.gwt.validation.Validation'/>
<!-- Specify the app entry point class. -->
<entry-point class=
'com.google.gwt.sample.MyApplication.client.MyApplication'/>
</module>
MyApplication.java
*
package* com.google.gwt.sample.MyApplication.client;
*
import* com.google.gwt.core.client.EntryPoint;
*
import* com.google.gwt.user.client.ui.Button;
*
import* com.google.gwt.user.client.ui.ClickListener;
*
import* com.google.gwt.user.client.ui.Label;
*
import* com.google.gwt.user.client.ui.RootPanel;
*
import* com.google.gwt.user.client.ui.Widget;
*
import* com.google.gwt.user.client.ui.TextBox;
*
import* eu.maydu.gwt.validation.client.ValidationProcessor;
*
import* eu.maydu.gwt.validation.client.actions.LabelTextAction;
*
import* eu.maydu.gwt.validation.client.actions.StyleAction;
*
import* eu.maydu.gwt.validation.client.validators.numeric.IntegerValidator;
/**
* Entry point classes define <code>onModuleLoad()</code>.
*/
*
public* *class* MyApplication *implements* EntryPoint {
/**
* This is the entry point method.
*/
*public* *void* onModuleLoad() {
*final* Button button = *new* Button("Click me");
*final* Label label = *new* Label();
*final* Label firstName = *new* Label();
*final* Label lastName = *new* Label();
*final* TextBox textBox=*new* TextBox();
*final* TextBox firstNameTxt=*new* TextBox();
*final* TextBox lastNameTxt=*new* TextBox();
TextBox birthYearTextBox = *new* TextBox();
Label errorLabel = *new* Label("");
Button validateButton = *new* Button("Validate!");
ValidationProcessor validator = *new* ValidationProcessor();
validator.addValidators( "birthYear",
*new* IntegerValidator(birthYearTextBox, 1890, 2009)
.addActionForFailure(*new* StyleAction("validationFailedBorder"))
.addActionForFailure(*new* LabelTextAction(errorLabel))
);
button.addClickListener(*new* ClickListener() {
*public* *void* onClick(Widget sender) {
*if* (label.getText().equals(""))
label.setText("Hello World!");
*else
*
label.setText("");
}
});
// Assume that the host HTML has elements defined whose
// IDs are "slot1", "slot2". In a real app, you probably would not want
// to hard-code IDs. Instead, you could, for example, search for all
// elements with a particular CSS class and replace them with widgets.
//
firstName.setText("FirstName");
lastName.setText("LastName");
RootPanel.*get*("slot1").add(firstName);
RootPanel.*get*("slot2").add(firstNameTxt);
RootPanel.*get*("slot3").add(lastName);
RootPanel.*get*("slot4").add(lastNameTxt);
RootPanel.*get*("slot4").add(birthYearTextBox);
RootPanel.*get*("slot5").add(button);
RootPanel.*get*("slot6").add(label);
}
}
when I compile my application i get following error.:

Is there something obvious that I am missing?
