i've included /jdbc/lib/classes111.zip.  is there a separate OracleResultSet package?

You need to import oracle.jdbc.*, if memory serves, so that the OracleResultSet is visible in your code.

hi Jim Cakalic,

I imported oracle.jdbc.*
the compiler still can't find OracleResultSet.

Sorry, my memory _didn't_ serve me correctly. That should have been
    import 'oracle.jdbc.driver.*;

And, of course, the full path to classes111.zip (or classes12.zip) in the classpath.

thanks for the help jim.  i was able to find the object. but then i get this error during compilation.
**** begin of error ***********
 The method oracle.jdbc2.Clob getClob(java.lang.String) declared in class oracle.jdbc.driver.OracleResultSet cannot override the method of the same signature declared in interface java.sql.ResultSet.  They must have the same return type.  

********  end of error ************

the same message appears for getBlob, getRef, getArray ...
it seems that there's method name conflict with java.sql.*

is there a way to take of this?

thanks,
Johnny

Also,

I have my imports set up as this:

    import java.sql.Connection;
    import java.sql.ResultSet;
    import java.sql.Statement;
    import java.sql.PreparedStatement;
    import java.sql.SQLException;
    import oracle.sql.*;
    import oracle.jdbc.driver.*;
    import java.io.*;

now I get the error: that the compiler cannot find the Object "Clob"

First the compilation error. The conventional wisdom seems to be that there were some problems related to LOBs in early editions of the jdbc drivers. Several comments I have read indicate that using the latest edition (8.1.7) of the drivers will solve this. Oracle maintains excellent backwards compatibility so this shouldn't be a problem. The OTN download page links are wrong. Go directly to
    http://otn.oracle.com/software/tech/java/sqlj_jdbc/content.html

Also, is it necessary for you to use classes111.zip? This is for JDK 1.1.x environments. If you are using a Java 2 environment, you would be better served to download the drivers for Java 2 and use classes12.zip. Once you have the drivers, you can just drop the classes12.zip file in your lib directory and change the classpath.

As for your other problem, the Oracle javadoc seems to 'randomly' refer to oracle.jdbc2.Clob and oracle.sql.CLOB. I've looked through the driver classes and cannot find an oracle.jdbc2.Clob. I'm assuming that it is an old reference which hasn't been fixed in the javadoc. The class you want is oracle.sql.CLOB. Note that it is 'CLOB' and not 'Clob' -- all uppercase.

Hope this helps.
Jim
