Hello Friends,

In the hibernate.config.xml file we specify the connection properties. i have a java class which gives me a connection. how can i provide the connection of this java class to the hibernate config file. This is because, i cannot hard code the username and password in the config. The java class takes it from a password matrix and has its own connection pool. So i need to provide this connection to the hibernate config file. Can any one please suggest me how can i code for this.

Use a datasource. This is typically designed for this purpose.

Declare this datasource with jndi and configure hibernate to use this datasource (See hibernate.connection.datasource in the reference documentation).

then do you mean that

Configuration cfg = new Configuration()
setProperty("hibernate.connection.datasource", "java:comp/env/jdbc/test")

the "java:comp/env/jdbc/test" will be my java class returning the connection.

It depends on how you configure Hibernate. For example, with a classical config, it could just mean put the hibernate.connection.datasource tag in the hibernate.cfg.xml file.

But basically, yes, it's the same principle.


Well... Not a class.

Actually, Hibernate will retrieve a java.sql.Datasource with this property. But you don't even need to know it since it's managed in Hibernate internals and works fine :-).

could you please give me an example.... i am a bit new to hibernate and a bit confused........

JNDI has nothing to do with Hibernate. So you should read a bit about this, and then trying to use with Hibernate should be simpler.

See http://www.hibernate.org/hib_docs/v3/re ... -xmlconfig for hibernate.cfg.xml configuration file. This one uses a datasource, so the example is related to your needs, read it closely.

thank you very much....i think this is what i wanted....thank you....

Hi
I cant understand the difference between get connection by JNDI and
SessionFactory sf = new Configuration().configure().buildSessionFactory();
. which method is best and what is the difference between these two ways
.

thanks
mano

There's no difference in the code you show. But there's a difference in the Hibernate configuration.

JDNI is mainly recommended when working inside a managed environment (typically an appserver). In this case, you just have to give the jndi url to Hibernate so it can retrieve the connections from it.
