Hi,
I'm currently developing an application where we want to handle all the
exceptions within the application. When calling a persist on an entity which
violates a unique constraint in the entity, I'm unable to catch it with the
following code.
try {
// Use the Entity Manager to persist the given Object
manager.persist(obj);
return;
}
catch (IllegalArgumentException e) {
throw new DataLayerException(0, "persist", "Illegal
Argument", e.toString(), null, e);
}
catch (TransactionRequiredException e) {
//throw new DataLayerException(1, "persist",
"Transaction required", e.toString(), null, e);
return;
}
catch (Throwable e) {
throw new
DataLayerException(DataLayerException.UNKNOWN_EXCEPTION, "persist", "Unknown",
e.toString(), null, e);
}finally {
System.err.print("finally");
}
And it throws the following. I've trimmed the error down to the initial cause.
10:05:46,185 INFO [STDOUT] Hibernate: select PROGRAM.nextval from dual

Any help will be greatly appreciated.
