From where i can find out this file COM.ibm.db2.jdbc.app.DB2Driver ?
I need DB2 JDBC driver jar file. From where i can download it???

Go to DB2 installation path. (Eg "C:\Program Files\IBM\SQLLIB\java" if its windows). There you find db2java.zip. Rename this to db2java.jar and use it.

I don't use DB2, so forgive my lack of specific information. However, the application server is looking for a specific class, which it is not finding. This should be easy to track down.

First, make sure you've put the correct class name in your deployment descriptor. You show it as COM.ibm.db2.jdbc.app.DB2Driver. Is this correct? It begins with all upper-case COM? Make sure it's correct, including upper/lower case.

Next, look at the contents of the db2java.jar file (using Winzip if you have it, or just extract it into a temporary directory) and make sure that the class associated with that name exists. It will be in COM/ibm/db2/jdbc/app/DB2Driver.class. Make sure that all the name components match, including case.

If all that is right, then make sure the jar is really on the classpath of the application server. If you're starting the application server with a script (like run.sh or run.bat), you can edit that script and update the CLASSPATH setting to add this jar.

Good luck.
