Hi Ted,
No idea about MySQL, but for Postgres you need to subclass the PostgresqlSQLHelper and implement something like:
public boolean handleDatabaseException(EODatabaseContext databaseContext,
Throwable throwable) {
boolean handleDatabaseException = false;
if (throwable != null && throwable.getMessage() != null) {
if (throwable.getMessage().contains(
"unique_something")) {
handleDatabaseException = true;
databaseContext.rollbackChanges();
throw ERXValidationFactory.defaultFactory() .createCustomException(null, SomeEO.ATTRIBUTE_name, null, "DuplicateNameConstraintException");
}
}
return handleDatabaseException;
}
HTH, Fabian
