imake Mar 20, 2008 3:18 PM (in response to imake)

I saw the source of @Email annotation.
The core code is:

public boolean isValid(Object value) {
          if ( value == null ) return true;
          if ( !( value instanceof String ) ) return false;
          String string = (String) value;
                if ( string.length() == 0 ) return true;
                Matcher m = pattern.matcher( string );
          return m.matches();
}

If the value is null,it returns true.
But why I leave the field empty when I submit the form.I got invalidStateException.

imake Mar 20, 2008 3:22 PM (in response to imake)

Sorry,I forgot the User code.

User.java

@MappedSuperclass
public abstract class User {
    
    private String name;
    private String password;
    private String repassword;    
    private Date birthday;

    @NotEmpty
    @Length(min=2,max=4,message="#{messages['myValidator.name']}")
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }

    @NotNull
 @Length(min=6,max=16,message="#{messages['myValidator.password']}")
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }

    @Transient
    public String getRepassword() {
        return repassword;
    }
    public void setRepassword(String repassword) {
        this.repassword = repassword;
    }    

    @Temporal(TemporalType.DATE)
    public Date getBirthday() {
        return birthday;
    }
    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }    

}

When you submit a form, the value is an empty string which is not permitted.

I have extended validators just to have add a require flag such that it can pass on an empty string too. Wish there was an easier way but I have not found one yet.

Anyone else found an easier way?

What is going on is that Hibernate Validator which is bundled on JBoss 4.2.2 is not the latest one (server/default/lib/hibernate-annotations.jar).

I reported the problem you found the last year, and it is currently fixed as you can see on Hibernate Validator Issue (As you know).

Don't know if JBoss Server will update the library in the next versions, but you have two options:

a) Udpdate the JBoss hibernate libaries manually.

b) Write your own @Email validator.

I choose b) in the meantime.

HTH.

This is another thing I can't understand, but it is inside hibernate-annotations.jar (.../server/default/lib).

So, if you want to upgrade the hibernate-validator you must hack such a jar file.

Between versions of Hibernate Annotations, Hibernate Validator was split out into its own project.

What do you all recommend for resolving this issue?

1) Replace hibernate-annotations.jar in our JBoss server/lib directory?
2) Work around the @Email issue by using @Pattern or similar?
3) Anything else?

Thanks.

I have modified my getter and it works for me:

@Column
@Email(message="#{messages['validator.email']}")
public String getEmail() {
    // hibernate email validator causes an error when string is empty
    if (email != null && email.equals("")) {
        return null;
    }
    return email;
}
