I see three options:
A) To catch the Exception in your code and then show the respective message.
| public void create(Object entity) throws MyDuplicatedException {
| try {
| em.persist(entity);
| em.flush();
| } catch (EntityExistsException e) {
| throw new MyDuplicatedException();
| }
| }
|
|
B) To use @(protected) and @(protected) enabling a JSF Validator as Seam component.
| @(protected)("equalValidator")
| @(protected)
| public class EqualValidator implements javax.faces.validator.Validator {
| ...
| public void validate(FacesContext facesContext, UIComponent
uiComponent, Object value) throws ValidatorException {
| ...
| }
| }
|
|
| -- ---- ---- ---- ---- ---- ---- -----
|
| <h:inputSecret id="confirmPassword" value="#{user.confirmPassword}"
required="true"
| maxlength="40" redisplay="true" tabindex="3" styleClass=
"input">
| <f:validator validatorId="equalValidator"/>
| </h:inputSecret>
|
|
C) To implement custom Hibernate Validator (it will work with s:validate).
| public class MyEmailValidator implements Validator<MyEmail> {
| ...
| public boolean isValid(Object value) {...
| }
| ...
| }
| -- ---- ---- ---- ---- ------
|
| @(protected)
| @(protected)(EmailValidator.class)
| @(protected)({METHOD, FIELD})
| @(protected)(RUNTIME)
| public @(protected) MyEmail {
| String message() default "{validator.email}";
| }
|
|
|
| .............
| @(protected)
| public class User {
| ...
| @(protected)
| private String email;
| ...
| }
|
|
I used A) and B) and C) in different scenarios, but at the moment I din't use C
) to access database querying for some data. Maybe you can try making MyEmail
class a Seam component (which will allows you to access SMPC).
HTH.
