Hi,

I do want to set the username and password dynamically in hibernate.cfg.xml

Here below is my configuration file.

<?xml version='1.0' encoding='utf-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="hibernate.bytecode.use_reflection_optimizer">false</property> <property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property> <property name="hibernate.connection.pool_size">10</property> <property name="show_sql">true</property> <property name="hibernate.dialect">org.hibernate.dialect.OracleDialect</property> <property name="hibernate.hbm2ddl.auto">update</property> <property name="current_session_context_class">thread</property> <property name="show_sql">true</property> <!-- <mapping resource="/login.hbm.xml"/> --> </session-factory> </hibernate-configuration>

Also im getting that session factory object like the below code.

public class Sessions { private static SessionFactory sessionFactory; private static Configuration configuration = new Configuration(); static { try { String userName = GuigenserviceImpl.userName; String password = GuigenserviceImpl.password; String hostName = GuigenserviceImpl.hostName; String portNo = GuigenserviceImpl.portNo; String sId = GuigenserviceImpl.sId; // Create the SessionFactory from hibernate.cfg.xml configuration .setProperty("hibernate.connection.username", userName); configuration .setProperty("hibernate.connection.password", password); configuration.setProperty("hibernate.connection.url", "jdbc:oracle:thin:@" + hostName + ":" + portNo + ":" + sId); try { configuration.configure("/hibernate.cfg.xml"); sessionFactory = configuration.buildSessionFactory(); GuigenserviceImpl.strAccpted = "true"; } catch (Exception e) { // TODO: handle exception System.out.println("Exception in implementation class: "); e.printStackTrace(); GuigenserviceImpl.strAccpted = "false"; } } catch (HibernateException hibernateException) { GuigenserviceImpl.strAccpted = "false"; hibernateException.printStackTrace(); } catch (Throwable ex) { // Make sure you log the exception, as it might be swallowed GuigenserviceImpl.strAccpted = "false"; ex.printStackTrace(); throw new ExceptionInInitializerError(ex); } } /** * The session factory is created at class load time and is * provided here. */ public static SessionFactory getSessionFactory() { return sessionFactory; }

So, in this above scenario, suppose if im giving the wrong password means exception should be caught and the string variable "GuigenserviceImpl.strAccpted" should be assigned to false.

But im getting the SQL Exception only in console like wrong username and password. And finally i couldn't able to catch the exception in Sessions class, static block.

Anyone can help me in catching that SQL Exception in my Sessions class and i need to handle that SQL Exception in my class.

Im getting this following exception message in my console.
