Dear Friends,

I am trying to access mysql database through JNDI but I am not able to access it. I am not much familiar to JNDI. I am sending you the coding part of my programs. Kindly help me and tell where am I making a mistake -

When I used simple statement

java DatabaseCheck

to run the code, following error message flashed -

I later used the following command for running the application -

java -Djava.naming.factory.initial=com.mysql.jdbc.Driver -Djava.naming.provider.url=jdbc:mysql://localhost:3306/studentDB DatabaseCheck

Then following error msg flashed -

The user of mysql is root and password is mysql@123. Is there something extra needed to be done.

Please tell where I am commiting mistake? Suggestions are welcomed.

Waiting for your response friends.

-Djava.naming.factory.initial=com.mysql.jdbc.Driver -Djava.naming.provider.url=jdbc:mysql://localhost:3306/studentDB

These are supposed to be JNDI related implementation details. They do not have anything to do with JDBC, thus the class cast exception.

Change the factory and procider URL to reflect the right values

Check your config file also. config file of server.
