this is the setting in resource.properties:
jdbcDataSource.5.name=jdbc/Oracle
jdbcDataSource.5.url=jdbc\:oracle\:thin\:@nicole\:1521\:NICOLE
jdbcDriver.1.name=oracle.jdbc.driver.OracleDriver
this is my classpath setting:
%J2EE_HOME%\lib\j2ee.jar;%J2EE_HOME%\lib\system\cloudscape.jar;%J2EE_HOME%\lib\system\cloudutil.jar;%J2EE_HOME%\lib\cloudscape\RmiJdbc.jar;%J2EE_HOME%\lib\system\classes12.jar;.
since i already declare classpath for oracle JDBC Driver (classes12.jar), why the program still can't found the oracle.jdbc.driver.OracleDriver? please help. thanks.

catch(ClassNotFoundException cnfe)
     out.println("Failed to load Jdbc Odbc driver");
try{
Connection con = DriverManager.getConnection("jdbc:oracle:thin@localhost:1521:ORACLE9I","scott","tiger");
Statement ps = con.createStatement();
try{
ResultSet rs = ps.executeQuery("select * from empDetails");
while(rs.next())
     out.println(rs.getString(1));
     out.println(rs.getString(2));
rs.close();
}catch(SQLException se)
out.println(se);
