Problems connecting to an oracle db whit servlets

Question

hi there!
I am trying to connect to my Oracle database. When I write my program as a JSP It connects but when I use the same within a servlet.
It does not work!!!
I use
- Tomcat 4.1.24
- J2SDK 1.4.2
By the way, I have already put the Oracle JDBC JARs (classes12.jar & classes111.jar) in the
TOMCAT_HOME/common/lib directory so my JSP's can find them and they run very well.
And I have defined the CLASSPATH environment variable
Also I have included the JARs files in my lib directory.
TOMCAT_HOME\webapps\myweb\web-inf\lib
But when i try to compile my servlets can't find the JARs files.
This is the error that I got while compiling.
servletdb.java:22: unreported exception java.lang.ClassNotFoundException; must be caught or declared to be thrownClass.forName("oracle.jdbc.driver.OracleDriver").newInstance();

servletdb.java:22: unreported exception java.lang.InstantiationException; must be caught or declared to be thrownClass.forName("oracle.jdbc.driver.OracleDriver").newInstance();

Connection dbconn=DriverManager.getConnection("jdbc:oracle:thin:@url:port:dbname","user","pw");
out.println("You are connected (Too)!<br>");
out.println("Congratulations!!<br><br>");
Statement stmt=dbconn.createStatement();
ResultSet rs=stmt.executeQuery(queryString);
while(rs.next())
out.println(" <tr><td>" + rs.getString(1));
out.println("</td><td>" + rs.getString(2));
out.println("</td><td>" + rs.getString(3));
out.println("</td><td>" + rs.getString(4));
out.println("</td><td>" + rs.getString(5) + "</td></tr>");
rs.close(); // need to close all of these
stmt.close(); //
dbconn.close(); //
thanks in advance
