This is my Servlet class

This is the model class

This is the class for getting connection to the Database

This is the code to add a movie to the pyramid table.. When i executed it including main method the insertion is happened but when i removed the main method it's showing an error "Class not foundjava.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver
11:10:11,022 INFO [STDOUT] java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver
11:10:11,023 INFO [STDOUT] Could not connect to DBjava.sql.SQLException: No suitable driver found for jdbc:oracle:thin:@
11:10:11,024 INFO [STDOUT] Exceptionjava.lang.NullPointerException"

How can i overcome this error? help me

Thank you very much... It worked!!!The ping succeeded

amit punekar wrote:Hi,
Two things to check
1) Do you see the Class for which ClassNotFound is thrown in the JAR that you added in Eclipse
2) Right click the java project and check the Java Build Path. It should have correct location of the JDBC driver's Jar file.


Thank you Amit For your Reply The ClassNotFound problem is resolved but still i got SQL exception saying that the network adapter could not establish the connection

Dieter Quickfend wrote:Then you have a problem connecting. Check if all your data is correct... Username, password, driver string, hostname, and port.

driver string:jdbc:oracle:thin:@localhost:1521:ORCL

the username and password are working as i checked that with my oracle sql puls..
i'm using eclipse galileo.. In that i created a new database connection selecting Oracle.... In the new Driver definition(oracle thin driver 10) i made modifications like removing the classes14 jar,adding the classes12 jar, setting the SID,username ,password... i made these modifications in the properties also... When i click the test connection button it says the ping failed

James Sabre wrote:You need to add the Oracle JDBC driver jar to your class path. When you use this in your servlet the driver jar must be placed in the WEB-INF/lib directory of your war file.

I'm using eclipse galileo.... still do i need to add? I added the classes12.jar file in my database connections....even the pinging also failed....
