Hibernate basic configuration example
Hibernate Configuration
This example demonstrates how to configure hibernate framework for running a simple
standalone program. Here the sample program uses programmatic configuration to set
all the properties required for running hibernate. Also the example uses derby as the
database to connect and update the values. This is not the big change, you only have to
change few parameters if you are using any other databases.
The following are the jar files required to run this example:
- hibernate3.jar
- dom4j.jar
- commons-logging.jar
- derby.jar
- commons-collections.jar
- cglib.jar
- asm.jar
- cuncurrent.jar
- jta.jar
