Bean validation on class level [duplicate]

Bean validation on class level [duplicate] - java

I am trying to implement a crossfield validation (JSR-303) with a custom annotation on class level. However the isValid method is not called (but the initialize method).
So my question is: Why is the isValid method not being called for this class level validator? Defining it on property level works!
I tried it on JBoss AS 7 and Websphere AS 8.
Here is the code and a JUnit test (which works)
Test.java
public class Test {
#org.junit.Test
public void test() throws ParseException {
Person person = new Person();
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMDD");
person.setPartyClosingDateFrom(new Date());
person.setPartyClosingDateTo(sdf.parse("20120210"));
Set<ConstraintViolation<Person>> violations = Validation.buildDefaultValidatorFactory().getValidator().validate(person);
for(ConstraintViolation<Person> violation : violations) {
System.out.println("Message:- " + violation.getMessage());
}
}
}

Especially the property retrieval was taken from this post question

JSF 2.0 doesn't call class level validation constraints.
From JSF validation:
JSF 2 provides built-in integration with JSR-303 constraints. When you
are using bean validation in your application, JSF automatically uses
the constraints for beans that are referenced by UIInput values.
You have to call it manually, or you can try Seam Faces which has an extension <f:validateBean>

How do I achieve this, with the generated POJO above.

What you get is an output of default Java Object.toString() implementation and it is correct - your class does not override toString().
So, either check Axis2/SoapUI documentation about is there a way to generate toString() method or (if not)
depends on how do you want to see your object String representation you can:
override toString() after class generated
create some utility to convert your object to String
simplest way is to use Apache BeanUtils.describe(Object obj) method
but if you want see actual XML as string you need to use one of serialize methods generated for you by Axis2.
something like:
// use ByteArrayOutputStream as example
ByteArrayOutputStream outStream = new ByteArrayOutputStream();
XMLStreamWriter xmlWriter = XMLStreamWriterFactory.create(outStream);
// fake line !!! check Axis2 documentation what you need to pass as Parent QName to Serialize an object
javax.xml.namespace.QName parentQName = new javax.xml.namespace.QName("http://tempuri.org/","FacValidityRequest", "ns1");
// This is a main point to get a XML String out of POJO
myFacValidityRequestObject.serialize(parentQName , xmlWriter);
System.out.println(new String(outStream.toByteArray()));
xmlWriter.close();
You need just find out what actual Parent QName parameter must be there (in my example it is just a fake one)

How to make a JAVADOC of my program?

This is my code:
public class Client
{
protected int cod;
protected String name;
public void setCod(int cod) throws Exception
{
if(cod==null)
throw new Exception("Invalid code!");
this.cod = cod;
}
public int getCod()
{
return this.cod;
}
public void setName(String name) throws Exception
{
if(name==null || name.equals("")
throw new Exception("Invalid name!");
this.name = name;
}
public String getName()
{
return this.name;
}
public Client(int cod, String name) throws Exception
{
this.setCod(cod);
this.setName(name);
}
public boolean equals(Object obj)
{
if(this==obj)
return true;
if(obj==null)
return false;
if(!(obj instanceof Client))
return false;
Client client = (Client)obj;
if(this.cod!=client.cod)
return false;
if(this.name!=client.name)
return false;
return true;
}
public String toString()
{
return "Code: " + this.cod + "\n" +
"Name: " + this.name;
}
public int hashCode()
{
int ret = 444;
ret += ret*7 + new Integer (this.cod).hashCode();
ret += ret*7 + (this.name).hashCode();
return ret;
}
public Object clone()
{
Client ret = null;
try
{
ret = new Client(this);
}
catch(Exception error)
{
// this is never null
}
return ret;
}
public Client(Client model) throws Exception
{
if(model==null)
throw new Exception("Inexistent model!");
this.cod = model.cod;
this.name = model.name;
}
}
I know that, to make a comment, you'll have to put "//" or " /* " and " */ ". But how can I comment following the JAVADOC rule?
If you know how, can you copy my code and put it in your answer, with the JAVADOC? Thanks :)
And please tell me, what is a JAVADOC, and what is it for? Is there any simple way to make it?

Javadoc is a kind of comment that you use in your program, to organize it, to make the program more friendly and to create a page HTML with everything you commented, like this:
So, to create a javadoc, you'll have top put /** in place of /*.
There is types of commands that you need to know when you're creating the javadoc.
#author - who created the program
#throws - for exceptions
#param - the method parameters
#return - what the method returns
So, your code with javadoc will be like this:
/**

*/
public class Client
{
protected int cod;
protected String name;
/**
* instance the code passed
*/
public void setCod(int cod) throws Exception

How do I modify the Month and Year Controls on JavaFX 8's DatePicker?

For an application I'm developing, a lot of older clients with larger fingers and poor eyesight need the selection arrows and Date/Year labels to be larger on the DatePicker Pop-Up.
In the documentation of the DatePicker class, there are methods described for modifying the DateCells within the calendar itself, but nothing describes or elaborates on the construction of the popup any further. (At least, the code is not self-documented plainly enough for my entry-level knowledge of Java development to grasp any hints)
My implementation ends up looking like this
Sometimes when I open and close the calendar, the size of the font and buttons in the Month/Year controls fluctuate, but I have no idea how or why. I assume some CSS may be tampering with it, but I have no idea why it would sometimes work and sometimes not. CSS' true nature has always escaped me.
I know it [DatePicker] is based on a ComboBox, but I have absolutely zero idea how it is constructed and fully implemented, much less how to modify very specific elements in it.
Is there a method I can call/Override, or a parameter I can modify in-line to style these properly? Also, could there be a combination of classes and elements I can call in CSS to style these to avoid having to outright modify DatePicker itself as described above?
Here is my implementation:
#FXML private DatePicker dPicker;
final Callback<DatePicker, DateCell> dayCellFactory =
new Callback<DatePicker, DateCell>() {
#Override
public DateCell call(final DatePicker datePicker) {
return new DateCell() {
#Override
public void updateItem(LocalDate item, boolean empty) {
super.updateItem(item, empty);
setMinSize(100,100);
setStyle("-fx-font-size:50px;-fx-font-weight:bold;");
}
};
}
};
dPicker.setDayCellFactory(dayCellFactory);
...and here is DataPicker.java:

The best way to change appearance like this is to use an external CSS. You can refer to the source code for the default stylesheet to see how the defaults are defined: the interesting parts for the DatePicker are near the bottom (lines 2932 onwards at the time of writing).
You can change the font size for the entire control just by doing
.date-picker {
-fx-font-size: 18pt ;
}
That ends up looking a little cluttered, so adding a bit of padding around the day names helps. The arrows will automatically scale to fit, so they will increase size with the increased font size on the month and year labels.
Here's a complete example:
import java.time.Instant;
import java.time.LocalDateTime;
import java.time.ZoneId;
import java.time.ZonedDateTime;
import java.util.Date;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.DatePicker;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class DatePickerExample extends Application {
#Override
public void start(Stage primaryStage) {
DatePicker datePicker = new DatePicker();
VBox root = new VBox(datePicker);
Scene scene = new Scene(root, 250, 150);
scene.getStylesheets().add("date-picker-readable.css");
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
date-picker-readable.css:
.date-picker {
-fx-font-size: 18pt;
-fx-font-weight: bold ;
}
.date-picker .day-name-cell {
-fx-padding: 10px ;
}

Loss of types in the abstract factory

I am developing an java application that accepts SOAP message. The body of the SOAP contains various documents. From time to time their number varies (depending on the version of the album).
For their analysis I am trying to apply a pattern Abstract Factory.
But my implementation, I ran into a problem:
IAlbumFactory albumFactory = AlbumFactory.buildDocument (Album.A_5_0_12);
The first parameter has I can point to any type of enum CustomDocument (although CustomDocument.DO1 only valid Du). And this error only shows up in RunTime
IDocumentEntity <Du, org.w3c.dom.Element> documentEntity =
albumFactory.getWorker (CustomDocument.DO1);
how to avoid it?

public interface IDocumentEntity<T,E> {
T getReport(E e) throws JAXBException ;
}
public interface IAlbumFactory {
IDocumentEntity getWorker(CustomDocument document);
}
/**
* Class for convert document DO1 (album 5.0.12) from org.w3c.dom.Element to Du
* entity type

JAXBContext result = JAXBContextHelper_DO1.getJaxbContextInstance();
Unmarshaller u = result.createUnmarshaller();
Object c = u.unmarshal(e);
if (c instanceof JAXBElement) {
JAXBElement jaxbe = (JAXBElement) c;
resultType = (DO1ReportInType) JAXBIntrospector.getValue(jaxbe);
}
return resultType;
}

This is the error I'm getting.
Is there any standard way to validate DateTimeField?
package validators;
import java.text.ParsePosition;
import java.text.SimpleDateFormat;
import org.apache.wicket.extensions.yui.calendar.DateTimeField;
import org.apache.wicket.validation.IValidatable;
import org.apache.wicket.validation.IValidator;
import org.apache.wicket.validation.ValidationError;
public class DateTimeFieldValidator implements IValidator<DateTimeField> {
/**
*
*/
private static final long serialVersionUID = 2342344609244L;
public DateTimeFieldValidator() {
}
private void error(IValidatable<DateTimeField> validatable, String errorKey) {
ValidationError error = new ValidationError();
error.addMessageKey(getClass().getSimpleName() + "." + errorKey);
validatable.error(error);
}
public void validate(IValidatable<DateTimeField> validatable) {
DateTimeField dateTime = (DateTimeField) validatable.getValue();
if ( dateTime== null){
error(validatable, "invalid.datetime");
}
else{
if( dateTime.getHours()!=null){
if( dateTime.getHours()>12 || dateTime.getHours()<0){
error(validatable, "invalid.hour");
}
}
else{
error(validatable, "invalid.hour");
}
if(dateTime.getMinutes()!=null){
if( dateTime.getMinutes() > 60 ){
error(validatable, "invalid.hour");
}
}else {
error(validatable, "invalid.minutes");
}
if( dateTime.getDate() == null ){
error(validatable, "invalid.date");
}
}
}
boolean isLegalDate(String s) {
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
sdf.setLenient(false);
return sdf.parse(s, new ParsePosition(0)) != null;
}
}
This is how I'm adding the validator.
startDateTimeField.add(new DateTimeFieldValidator());

Your DateTimeFieldValidator must implement IValidator<Date> instead of IValidator<DateTimeField>

I end up validating the datetimefield following way ..
And find out the datetimefield( yui ) have built in validation - which actually take care of the all the basic validations.
All you have to do is put a XXX.properties file in the folder -
you can also add your own error key and message - like I used startDate.after.enddate
IFormValidator validator = new AbstractFormValidator() {
/**
*
*/
private static final long serialVersionUID = -3252346839511722L;
public FormComponent<?>[] getDependentFormComponents() {
return new FormComponent[] { startField, endField };
}
ValidationError error = new ValidationError();
public void validate(Form<?> form) {
Date startDate = (Date) startField.getConvertedInput();
if(endField.isEnabled()){
Date endDate = (Date) endField.getConvertedInput();
if (endDate.before(startDate)){
error.addMessageKey(getClass().getSimpleName() + "startDate.after.enddate");
startField.error(error);
}
}
}
};
logForm.add(validator );
