JSP, Sql Server 2000 Driver, classpath

Question

Hello All,
I've got a really weird problem here.
I want to connect a JSP page to a SQL Server 2000 database.
I downloaded the SQL Server 2000 Driver for JDBC, and it seems to have installed fine.
Next I write a regular java program to test the connection. It works fine, I get a "Connection Successful message". Here' the code:
import java.sql.*;
public class MSSqlServerJDBCTest {
    public static void main( String args[] ) {
        Connection conn;
        if ( args.length != 3 ) {
            System.out.println( "Usage: java MSSqlServerJDBCTest "
                + "<server> <username> <password>" );
        } else {
            try {
                String serverName = args[ 0 ];
                String userName = args[ 1 ];
                String password = args[ 2 ];
                String connStr = "jdbc:microsoft:sqlserver://"
                    + serverName + ":1433";
                Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver" );
                conn = DriverManager.getConnection(
                    connStr, userName, password );
                System.out.println( "Connection successful" );
                conn.close();
            catch ( SQLException e ) {
                System.err.println( "SQL Exception: " + e.getMessage() );
            catch( ClassNotFoundException e ) {
                System.err.println( "SQL Server JDBC Driver Not Found!!" );
}Now, when I include similar into a JavaBean, which is used in a JSP, I get a classNotFound exception:
Exception occured: java.lang.ClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriverSo then I checked out the classpath a few times using echo %classpath%
Everything seemed okay, the driver jars are in the path, but the JSP can't find the driver.
I looked at the System.out file in the j2sdkee1.3.1\logs..... directory.
The start of the file contains this stuff:
Logging for J2EE Server Version: 1.3.1-b17 started at: Fri Nov 08 17:31:53 GMT 2002..
Using the Java HotSpot(TM) Client VM and the version number 1.3.1_02 from Sun Microsystems Inc..
VM is using the classpath: c:\j2sdkee1.3.1\lib\system\cloudscape.jar;c:\j2sdkee1.3.1\lib\system\tools.jar;c:\j2sdkee1.3.1\lib\cloudscape\RmiJdbc.jar;c:\j2sdkee1.3.1\lib\cloudscape\cloudclient.jar;c:\j2sdkee1.3.1\lib\classes;c:\j2sdkee1.3.1\classes;c:\j2sdkee1.3.1\lib\j2ee.jar;c:\j2sdkee1.3.1\lib\toolclasses;c:\j2sdkee1.3.1\lib\j2eetools.jar;c:\j2sdkee1.3.1\lib\locale;;c:\jdk1.3.1_02\lib\tools.jar;c:\j2sdkee1.3.1\lib\jhall.jar .
J2EE Home Directory has been set to: c:\j2sdkee1.3.1.Look at the classpath - its different from when I do an echo %classpath% from the command line. Notice also it DOESN'T contain the driver jars that I need. This is probably why I can connect from a regular java program, but not from within J2EE.
So where does this leave me? How can I change the classpath so that the changes are seen from within the J2EE container?
Please help,
Thanks in advance,

Answer 1

I modified the C:\j2sdkee1.3.1\bin\userconfig.bat file with the line:
set J2EE_CLASSPATH=c:\sqldriver\msutil.jar;c:\sqldriver\mssqlserver.jar;c:\sqldriver\msbase.jarI had to change the location of the MS SQLServer 2000 driver cos J2EE.bat wouldn't start with the original location. I don't think it liked the spaces.
Now I get a different exception:
