Connecting to Oracle 9i with Sun One Web Server 6.1 SP4

Question

I have an application that connects to an Oracle 9i database. When I run iPlanet 4.1, I am able to login to the application and run it. Since I have migrated to Sun One Web Server 6.1 SP4, I have not been able to login. Through some built in error logging, I have been able to determine that my user validation routine is receiving a Null pointer when it trys to connect to the database. I have also determined that my login servlet is executing properly. When I receive the Null pointer error, I am redirected to a failed login page, which is what is supposed to happen in such a case. I believe that I do not have the web server configured properly to connect to the database and I am not sure how to do it! Below is an excerpt from my code where the database connection occurs and the exception is detected. Any help would be appreciated!
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
          oracleConnect = DriverManager.getConnection("jdbc:oracle:thin:@" + chost + ":" + cport + ":" + csid ,u,p);
     enable = true;
oracleConnect.close();
}catch(java.sql.SQLException e){processError.logError("validateUser Invalue user" + e.getMessage()); enable = false;}
catch(java.io.FileNotFoundException e){processError.logError("validate User error" + e.getMessage());}
catch(java.io.IOException e){processError.logError("evalidateUser rror File Error " + e.getMessage());}
catch(java.lang.NullPointerException e){processError.logError("validateUser error Null Pointer " + e.getMessage());}

You are not using the server's built in JDBC Connection pooling, so there is no special WebServer configuration needed to connect to a database.
If in the other hand, you want to use the built in connection pooling, then refer to this page to see how to create a connection pool

Samples on how to configure and use JDBC connection pooling can be found in the sample apps
