OpenXava is a JPA Application Engine. You put in your JPA classes and, in exchange, you obtain a full-featured application ready for production, and without code generation. Since OpenXava 3.0.1, which was released this week, Hibernate Validator is fully supported.

So now you can write a Java class like this:

@Entity
@IdClass(DrivingLicenceKey.class)
public class DrivingLicence {

@Id @Column(length=2) @Stereotype("NO_FORMATING_STRING")
private String type;

@Id @Max(2)
private int level;

@Column(length=40) @Required
private String description;

public String getDescription() {
return description;
}

public void setDescription(String description) {
this.description = description;
}

public int getLevel() {
return level;
}

public void setLevel(int level) {
this.level = level;
}

public String getType() {
return type;
}

public void setType(String type) {
this.type = type;
}

}

And you will have an application module as this one:

Note that we are using @Max, a Hibernate Validator constraint, on our property level:

@Id @Max(2)  
private int level;


Therefore, when the user tries to save the driving lincence @Max constraint will be enforced, and the validation message will be shown to the user if it fails.

What's new in 3.0.1?

  • Hibernate Validator full support. Messages thrown by Hibernate Validator are shown to the user as validation messages.
  • @Required, @PropertyValidator and @EntityValidator redefined as Hibernate Validator constraints.
  • Max size of textAreaEditor uses Javascript for control max size (even with Ctrl-V).
  • Action 'new' of CRUD put the view to the initial section.
  • Ant creation wizard on template projects asks for the project name. Now it's not needed edit the ant build files.
  • A lot of fixes. Look at changelog.
