COM.ibm.db2.jdbc.app.DB2Driver



Try using "com.ibm.db2.jdbc.app.DB2Driver", instead.
Is you driver jar file available in classpath?
Also are you using Windows or Unix system to run the app?

If you're sure that the jar file is in classpath, please check the complete path by opening the jar and see if the Driver file exists in the said location.

What kind of application is this, web/standalone? If standalone then how you invoke the class (i.e.: command)? If web/enterprise application, where have you put the driver jar?

Did you check if there are two jar files ( different versions), sitting in different location and if that is causing this confusion?

this is web appication, i used JDeveloper IDE, in Tools ---> Manage Library i Created my own library , after that i added the library to my project by Libraries and Classpath in project's properties.

i think there is no other jar file in different location, because when i remove the jar from classpath and run the application i got this exception
Missing class: COM.ibm.db2.jdbc.app.DB2Driver

i think the problem in the jar file itself, but i can't find any web site to download another version from this jar.

The db2java jar file contains COM capitalized. so i write the path of COM.ibm.db2.jdbc.app.DB2Driver class as in jar file.

Just to make sure, do you have the jar file in the lib directory inside the container once the application deployed? And have checked with the DB documentation for the compatible driver with what you have got?
