Thanks sir for your response
my version
oracle jdeveloper reales 1 (11,1,1,4,0)
I use business component
I make method
this metod wrote at enitity "EmployeesImpl"
public Number getMax() throws JboException
PreparedStatement stat=null;
ResultSet rs=null;
try {
String sql="select max(EMPLOYEE_ID)+1 from EMPLOYEES";
stat=getDBTransaction().createPreparedStatement(sql, 1);
rs=stat.executeQuery();
if (rs.next()) {
return new Number (rs.getInt(1));
} catch (Exception e) {
// TODO: Add catch code
//e.printStackTrace();
throw new JboException("error");
} finally {
try {
rs.close();
stat.close();
} catch (Exception e) {
// TODO: Add catch code
//e.printStackTrace();
// oracle.jbo.domain.Number
return new Number (1);
