I can't get my program to connect to the Oracle Server at my school where I have my database located. I was given a user name and password, used scott & tiger for the example, also given the url, but it still doesn't work. Am I doing something wrong here?

public class DataBean
private CachedRowSet rowSet;

// construct TitlesBean object
public void DataBean() throws Exception
//load the Oracle Driver
Class.forName( "oracle.jdbc.driver.OracleDriver" );

// specify properties of CachedRowSet
rowSet = new CachedRowSetImpl();
rowSet.setUrl( "jdbcracle:thin:@vali.******:1**1rcl" );
rowSet.setUsername( "Scott" );
rowSet.setPassword( "Tiger" );

rowSet.setCommand("SELECT * FROM courses");
} // end DataBean constructor
