Class not found error for COM.ibm.db2.jdbc.app.DB2Driver

Question

i have written this code:
import java.io.*;
import java.sql.*;
public class tryjdbc
{  public static void main (String args[])
{  try
{  Class.forName("COM.ibm.db2.jdbc.app.DB2Driver");  }
catch (java.lang.ClassNotFoundException e)
{  System.out.print(e.getMessage());  }
and once i try to run it, it gives out a class not found exception error.
I haven't changed anything with the classpath since I don't think the problem is with the classpath. I have read in the IBM Developer Kit for Java documentaton that the AS/400 Developer Kit for Java automatically adds the db2_class.jar file to the classpath. So why do I get a class not found exception error?

Answer 1

I was using Web Spehere 4.0.3 and trying to connect to a database on DB2 7.2. I was just following a tutorial and trying to get a handle on Web Sphere. I am running all of these on a Windows 2000 Operating System. Here are some of my observations :
a. db2java.zip packaged under %DB2ROOT%\SQLLIB\JAVA, does not work.
b. CLASSPATH needs to be set to %DB2ROOT%\sqllib\java12\db2java.zip
c. Include this as one of the packages in the package defined in
WebSphere, using the Java Perspective.
d. Ensure that case sensitivity is respected. All though the package
shows up as COM.ibm.db2.jdbc.app.DB2Driver, for some reason, it
will only accept com.ibm.db2.jdbc.app.DB2Driver.
With these settings, I was able to connect to a db2 database.
I am a little puzzled on the following. I did not include java.io package, but still it could print the messages. Did anybody have a similar experience
Thanks for this posting.
