    Does JBoss validate EntityBean length setting?

    Tony Mai Apprentice

      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
