question about following new user's road map

I am trying to follow the road map for new users and am having trouble. The roadmap says: place your JDBC driver jar file in the lib directory

What is the name of the JDBC driver jar file and where would I find it? Somewhere in the developer's kit?

Sorry if this sounds like a dumb question but I am a beginner and I really don't know the answer.

The JDBC driver jar file is specific to whatever database vendor/Java version/database version you are using. If you were using Postgres 8.0 w/ Java 5, it would be named postgresql-8.0-312.jdbc2.jar . By the way, I think you posted the question twice.

Which database are you using?

For MySQL you could use MySQL Connector/J 3.1, which can be downloaded here:

I thought I was using Hibernate as my database. I thought that was the whole point of downloading this package. Am I mis-informed?

The Java version I'm usning is the one I downloaded with jdk1.5._04.

Hibernate is not a database, it's a bridge to the database.

Hibernate is the layer that converts data from the relational representation in the database to object representation for using within java code.
It accesses and updates the database tables that contain the data.
So, yes, you must use a database.
If you are looking for open-source database, try MySQL - http://www.mysql.com/
or Derby - http://db.apache.org/derby/

Now I am confused. I am looking for something I can use to store, retrieve, and manipulate data in a database form (my experience is with the native database on IBM's AS/400 ot Iseries midrange computer). I have a basic understanding of Java and wanted to start using Java to accomplish the specific task of retrieving the data in the form of hand historys that you get from online Poker sites, and then organizing this data for analysis and presention in GUI form.

Mainly just a project that will help me gain experience in programming with Java, and help in my efforts to to gain skills outside of the dying niche I'm in, the IBM midrange world.

I was told by a Java programmer I know that Hibernate is a free database product I could use.

So am I correct in saying that Hibernate is not this, is not something like Access or DB2, but is more like SQL in that it is used to retrieve and manipulate the database? If so, isn't all this contained withing Java itself already?

Thank You. I will go through this tutorial and get back to you. One quick question, though. The tutorial says to take files like antlr.jar and cglib-full.jar and place them in your working directory. I have ant-1.6.2.jar and cglib-2.1.jar in the lib dir tht came with hibernate.

These are the same thing, right?
