Does JBoss validate EntityBean length setting?

[tonylmai]

Hi all,

Would JBoss validate an Entity's attribute for length?

@Entity
public class ExampleName implements Serializable {
...
 private String name;

 @Column(nullable = false, length=25)
 public String getName() {
...
}

when I invoke the following code

ExampleName ex = new ExampleName();
ex.setName("A long line that violates the max length set for ExampleName");

The server threw the following exception:

12:35:37,312 WARN [JDBCExceptionReporter] SQL Error: 8152, SQLState: 22001
12:35:37,312 ERROR [JDBCExceptionReporter] String or binary data would be truncated.
12:35:37,312 ERROR [AbstractFlushingEventListener] Could not synchronize database state with session

...
Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: String or binary data would be truncated.

while on the client junit test, I would receive the following error:

java.lang.reflect.UndeclaredThrowableException

It would be nice to have JBoss validate the length automatically without us having to declare Hibernate's validation explicitly. After all, we are using Hibernate within JBoss are we not?

Thanks
