could someone tell me that can i do?

Seems to be Database connection problem.

I don't understand one thing:
Which database are you using? MySQL or SQLServer???

In the config you have:


In the log:


Is there more than one configuration file in your classpath? I don't understand where these values come from.

(*) Plz make sure it is Driver and not Driber

Irshad

i'm working on MySQL

i dont't have in any file this
INFO DriverManagerConnectionProvider:103 - using driver: net.sourceforge.jtds.jdbc.Driver at URL: jdbc:jtds:sqlserver://localhost:1433/ISS

and i think i' wrong

could you tell me pls where to look for it

than you for your observation, i solved the problem

Is your database up and running?

Can you connect to it via commandline (>mysql)?

Plz post your directory structure.

Irshad

Good that you solved.

Plz post here what you did to solve the problem and put at your subject [SOLVED]

Irshad

<property name="connection.driver_class">oracle.jdbc.OracleDriver</property>
<property name="connection.url">jdbc:oracle:thin:@localhost:1521:XE</property>
<property name="dialect">org.hibernate.dialect.OracleDialect</property>
<property name="connection.username">system</property>
<property name="connection.password">manager</property>

i am getting following error when i run main class

INFO: HHH000422: Disabling contextual LOB creation as connection was null
