Can anyone post an example of retrieving data from a table using struts2,hibernate generic dao and spring? I am unable to run my code using struts2,hibernate(genericdao) and spring using oracle database. It gives the following errors:
applicationcontext failed to initialze
unable to load jdbc drivers
error action listeners

Have you googled for examples of using Struts2, Spring and Hibernate? There are tons of examples on the web. Also you can use Spring in Action, Struts2 reference book as well. Can we get some of the stacktrace as well? The information you've provided is not adequate enough.

Thanks

Do I need to connect to my database before i run the application?

Here is the log file

No, but you need the right jdbc drivers in the classpath when the application starts. As Amin suggested try following a tutorial. The Struts 2 team has some on their website.

i added the ojdbc14 jar in tomcat/lib.
The log is

Have you looked at all log files? Tomcat writes several log files? If there no other indicators about the reason of not being able to deploy you have to reconfigure your Tomcat logging.

I created an example to integrate struts,spring and hibernate based on the tutorial. I have an error which asks for hibernate.cfg.xml.
