Oracle8i with JDBC problem...

I've got a perplexing problem with communicating with and Oracle8i database with Java. I have what I believe to be all the required .class files from Oracle. The file I downloaded was classes111.zip which is the same name as the .zip file for Oracle7, but that's besides the point. When I try to connect, I issue the following command...

	String userName = "scott";
	String password = "tiger";
	String url = "jdbc:oracle:oci8:_at_tatooine:1521:test2";



	//

	// Where the computer name is 'tatooine', and the service name is


'test2'


	//


	DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
	conn = DriverManager.getConnection(url,userName,password);

I can connect, but my programs all crash after trying to get results back from SQL commands. Am I just doing something wrong? I used a different url to connect to an Oracle7 database and have no problems...

        String url = "jdbc:oracle:thin:_at_dee:1521:mii";

But that didn't effect my programs when I changed it. Any ideas?
