[GWT GWT]

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


















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 onModuleLoad().

*/
*

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.:

Analyzing source in module
'com.google.gwt.sample.MyApplication.MyApplication'
   [ERROR] Errors in

Is there something obvious that I am missing?

Facing problem in GWT,Spring,hibernate application

[GWT GWT]

Hi
I have done an GWT,Spring,hibernate application using the link
http://eggsylife.blogspot.com/2008/02/hibernate-spring-google-web-too...
 .

My application got open in hosted mode. When i click on search button "
onFailure "  method of  "TeacherModel " class got called.

When I am trying to debug the code, the flow from the following line

PupilCollection collection = (PupilCollection) ContextUtil.*getContext
*().getBean("pupilCollection");
is returning back to "TeacherModel" class.
but I am not getting any exception on this line.

Thanks in advance.
