NoClassDefFoundError: oracle/jdbc/OracleDriver

Question

I have a servlet that is supposed to connect to an oracle database select from a table and then return the results. This works in JDeveloper but when I try to deploy it to tomcat I get an error saying the following.
java.lang.NoClassDefFoundError: oracle/jdbc/OracleDriver
     at LoginServlet.doPost(LoginServlet.java:44)
     at javax.servlet.http.HttpServlet.service(HttpServlet.java:760)
     at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)
How can I resolve this problem ?

Answer 1

I have the same problem.
I wrote a simple program as follows.
import java.sql.*;
import oracle.jdbc.*;
import oracle.sql.*;
public class OracleConnect
public static void main (String args []) throws SQLException
          DriverManager.registerDriver (new oracle.jdbc.OracleDriver());
     Connection conn = DriverManager.getConnection ("jdbc:oracle:thin:@10.0.0.8:1521:ORCL","scott","tiger");
     Statement stmt = conn.createStatement ();
          ResultSet rset = stmt.executeQuery ("SELECT ename FROM emp");
          while (rset.next ())
     System.out.println (rset.getString (1));
rset.close();
stmt.close();
conn.close();
I am compiling like this.
C;>javac -classpath c:\oracle\ora92\jdbc\lib\classes12.jar;c:\oracle\ora92\jdbc\lib\nls_charset12.jar;. OracleConnect.java
Everything is fine upto now.
But at the time of execution
C:\>java OracleConnect
Java is crying like this.
Exception in thread "main" java.lang.NoClassDefFoundError: oracle/jdbc/OracleDri
ver at OracleConnect.main(OracleConnect.java:11)
Can any one help me to resolve this issue please? By the way, I did not install Jdeveloper. I am using command prompt to do the stuff.
Thanks,
