could not establish connection using struts to oracle data base

[Swetha Bhagavathula]

Hello .I am facing the following error when trying to insert values from my struts application into oracle database table.please help me to sort out the problem:

SEVERE: The web application [/StrutsApp1] registered the JDBC driver [oracle.jdbc.OracleDriver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.

java.sql.SQLRecoverableException: Io exception: The Network Adapter could not establish the connection

Thanks in advance

This has nothing to do with Struts and everything to do with how you are connecting to your database. Can you connect with SQLPlus? Can you connect with plain JDBC? Are you using your container's connection pool? If so, does it have a "test connection" function you can use?

Thankyou could rectify my error. I need to start the oracle server from services.msc when it is in disabled mode. then could connect my application to database.
