Hi,
CreateException thrown in ejbCreate does not find its way to the bean's
client. Instead, the client
gets the following exception:
//-BEGIN
java.rmi.ServerException: RemoteException occurred in server thread;
nested exception is:
java.rmi.RemoteException: Container cannot commit a transaction;
nested exception is:
javax.transaction.RollbackException
//-END
This exception is generated, if the INSERT in ejbCreate (included below
in this message) violates
a unique key constraint (for example).
After looking at the trace and the JOnAS source code, I had the
impression that somehow the
"entityContext.setRollbackOnly()" instruction is ignored (the execution
gets into the
"rctx.mustCommit()" branch in JEntityHome.postInvoke), but I am not
sure, since I am not familiar
enough with the architecture of JOnAS. Anyway, I think that the client
must get the
CreateException, if the EntityBean.ejbCreate throws it. Please, correct
me if I am wrong.

The bean method is:
//-BEGIN
public AccountBeanPK ejbCreate(int val_accno, String val_customer,
double val_balance)
throws CreateException {
// Init object state
accno = val_accno;
customer = val_customer;
balance = val_balance;
// Create the primary key
AccountBeanPK pk = new AccountBeanPK(val_accno);
try {
// get a connection for this transaction context
Connection conn = getConnection();
// create object in DB
PreparedStatement stmt = conn.prepareStatement("insert into
accountsample (accno, customer, balance) values (?, ?, ?)");
stmt.setInt(1, pk.accno);
stmt.setString(2, customer);
stmt.setDouble(3, balance);
stmt.executeUpdate();
// close statement
stmt.close();
// release connection
conn.close();
} catch (SQLException e) {
e.printStackTrace() ;
System.err.println( "Error code: "+e.getErrorCode() ) ;
entityContext.setRollbackOnly() ;
throw new CreateException("Failed to create bean in database");
}
// Return the primary key
return pk;
}
//-END
On the server side the following trace has been produced:
