Can't load DB2 driver!

I have a Java app I run from the command line that can access my DB2 database. However, when I put my code into Websphere as a Servlet, it won't connect. Same driver, same dbURL, same everything, but it won't connect. I'm wondering if I have to configure my webapp in the Admin Console or something. I see there is a node called JDBC driver, but I can't do anything to it, I can't open it, edit it, or anything. What am I doing wrong? Help!

sorry i have not ur answer.
please give me connecting string databse DB2.
ur DB2 server on which OS. may be there driver problem?
but plz give me connecting string

Can't load jdbc driver in servlet

Dear All,
I have tried to connect to MS SQL SERVER 2000 through JDBC DRIVER FOR
SQLSERVER. However I receieved an error: can't load jdbc driver class:
null.
The following steps were what I did:
1.Set up SQL Server and create a few tables and users.
2.Config Server.xml
Add the following codes in /tomcat/conf/Server.xml
<Context path="/persistence" docBase="persistence" debug="0"
reloadable="true">
          <Resource name="jdbc/persistenceDB" auth="Container"
type="javax.sql.DataSource"/>
          <ResourceParams name="jdbc/PersistenceDB">
               <Parameter>
                    <name>user</name>
                    <value>kitty</value>
               </Parameter>
               <Parameter>
                    <name>password</name>
                    <value>abc</value>
               </Parameter>
               <Parameter>
                    <name>driverClassName</name>
                    <value>com.microsoft.jdbc.sqlserver.SQLServerDriver</value>
               </Parameter>
               <Parameter>
                    <name>url</name>
<value>jdbc:microsoft:sqlserver://localhost:1433;databaseName=persistence;selectMethod=cursor;</value>
               </Parameter>
          </ResourceParams>
</Context>
3.Config my web application's web.xml
Added the following piece of code in WEB.XML
<resource-ref>
<res-ref-name>jdbc/persistenceDB</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
4.Use Datasource in my code
package persistence.database;
import java.sql.*;
import javax.naming.InitialContext;
import javax.sql.DataSource;
import javax.servlet.ServletContext;
import persistence.*;
import com.microsoft.jdbcx.sqlserver.*;
import javax.naming.Context;
public class DatabaseAuthenticator implements Authenticator {
private DataSource ds;
public void init(ServletContext sctx) throws Exception {
InitialContext init = new InitialContext();
try{
     Context ctx = (Context) init.lookup("java:/comp/env");
ds = (DataSource) ctx.lookup("jdbc/persistenceDB");
} catch (Exception e) { e.printStackTrace();
public User authenticate(String username, String password)
throws AuthenticationException, UnknownException {
Connection conn = null;
PreparedStatement pstmt = null;
ResultSet rs;
try {
if (ds != null) {System.out.println("Success to get
datasource");
        } else {System.out.println("Failed");}
System.out.println(ds.toString());
try
conn = ds.getConnection();
catch (Exception e)
e.printStackTrace();
pstmt = conn.prepareStatement("SELECT user_id " + .........
5. put msutil.jar, mssqlserver.jar and msbase.jar under /tomcat/common/lib/.
When I tried to run the program, I receieved an error: can't load jdbc
driver class: null.
I've got no idea what's going on.
Any Suggestion?
Thanks in advance
Kitty

Hi Kitty,
The connection you're trying to set up points to nothing :
Connection conn = null;
So, you receive a complaint that that driver cannot be loaded. Please read
http://java.sun.com/docs/books/tutorial/jdbc/basics/connecting.html
download the right database driver and use that. Good luck!

I can't load the driver for a canon ir c2550.

I can't load the driver for a canon ir c2550. Installer gets to where it looks for the drive and never finds it. Drive only has 18G of space left. Help??
I have an early 2008 MacBook Pro
Thanks!!

Thanks so much for your response
I reset printer systems, and was only able to add Canon MG6200 series, either with Bonjour or Canon IJ Network, but cannot find the correct printer software for MG6250 (there is no option for any Canon MG printers) the only choice is Generic PostScript Printer.
I have tried using this, but the print job is not going to the printer itself, it appears that it is, but then under the canon print box, it simply dissappears.
Paul_31
At this point is the printer connected to the Mac via a USB cable?
Do you think that I should attach the printer with the old usb cable from my previous printer and try that appears to defeat the purpose of having a wifi printer Or will this simply allow the computer to find the printer and then I can remove the cable? Thanks

Strange that this function worked well when executed from the development software (before packaging it into jar file). Is there a difference in the way the program works as executable jar file and as the file in the development sofware?
And regarding the JDBC driver, I did try another driver, which was the JDBC type 2 and 4 driver. But when I ran the application, there's an error saying that the DB2 server does not support type 2 or 4 JDBC driver. Seems like I have no other choice but to use this driver.
Do you have any suggestion on how to make the driver work as an executable Jar file? Meanwhile, I'll try to report the bug for this driver. Thanks....

Can't load vboxdrv driver on lts kernel

I am having trouble starting vbox machine on 3.14.28-1-lts kernel after recent update.
I got virtualbox-host-modules-lts and checked https://wiki.archlinux.org/index.php/VirtualBox so everything looks good in general...

I was also having problems. I took Rokixz advice and built virtualbox-host-modules-lts from abs. This fixed it for me.

What's strange is that the "Version" is the same - 4.3.20-2, but the "Installed Size" varies... 167 KiB vs 187 KiB.
Also, the build date on the virtualbox-host-modules package (still the current one in the repos) was Dec 8, 2014... The linux-lts package build date is Jan 16, 2015.

Can't load JDBC Driver

Hi,
I can't load my JDBC driver for SQLserver database to
opening my DB with a servlet ...
platform : Windows 2000 server
servlet container : Jakarta-tomcat 3.2.2
jdk : jdk1.3
After executing the servlet which load the JDBC driver, the following message was appearing:
"ClassNotFoundException, java.lang.NullPointerException"
Thanks for your help.

Looks like the servlet is not able to find the required class in the package...Tomcat rewrites the classpath....So you might want to look at /bin/tomcatEnv.bat and modify it accordingly....Of course, check your classpath env variable to see if all the necessary zip/jar files are included.

Can't load line6usb driver module after installing from AUR

I downloaded the line6usb package from the AUR. After building then installing with pacman I should be able to load the module ala modprobe line6usb, but I get the error:
FATAL: MOdule line6usb not found.
I looked for the module itself and found it here(assuming this is it):
/lib/modules/2.6.27-ARCH/extra/line6usb.ko
Does anyone have an idea why I can't load this module? I'm still quite the noob with concerning things like this and I'm assuming it's something obvious I need to do.

Can't load ASIO driver / device could not be opened error in Audition CC but not Audition CS6

I have a M-Audio Fast Track Ultra USB 2.0 that I use for audio. I installed Audition CC and it wont let me use the ASIO driver for it. I get the device could not be opened error. On the same system I have Audition CS6 which works with the ASIO driver fine. Also have Vegas, Premiere, etc - all on the same machine and no problems with the M-Audio driver. I can load the Blackmagic ASIO driver but don't use that for audio mixing. Changing Use Machine Specific Device Defaults and Force Hardware to Sample Rate does nothing. Running Windows 7 64 bit.

M-Audio 64-bit driver is apparently troublesome, but the 32-bit one works fine - which explains why CS6 works and CC doesn't. As far as I can find out, you aren't the only person with this problem - have a look at this Reaper forum thread - you may get some useful information from it (no promises!)

Satellite L550 - Can't load sound driver in Win XP

I bought a Satellite L550 with Vista preinstalled and want to use XP.
I have loaded XP and have no sound device.
I downloaded the Sound Driver TC40072000A.exe but when I execute it, it extracts and then does nothing.
Maybe I need some other drivers loaded first?
Please help, thanks,
John

Hi
The notebook needs an Realtek HD sound driver.
You can download such driver directly from the Realtek driver page.
But before you would try to reinstall the sound driver, you will need to update the Win XP!
All service packs SP2 and SP3 have to be installed!!!!
This is very important since the SP3 contains necessary patches and fixes.
After the SP3 installation you could follow with sound driver

try adding the import statement for the oracle driver, which is

and don't forget to add your oracle driver in the classpath..
hope this helps..

Can't load jdbc driver from localhost

I'm having problems loading the jdbc driver from localhost when using a java com object in ASP.
The simple class compiles fine and runs perfect from dos command line but gives this exception when run from personal webserver:
java.lang.ClassNotFoundException: sun/jdbc/odbc/JdbcOdbcDriver
Obviously, it is not finding the jdbc driver, but what is the problem? It finds the driver when run from dos locally. Do I need a 3rd party driver when using as a COM object?
Here is a code snippet:
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection TestConnection = DriverManager.getConnection("jdbc:odbc:systemDSN", "username", "password");
Any help is appreciated, thanks!

I don't think it's exactly a classpath problem. I think when you run from the DOS command line, you are using the java.exe program that contains Sun's JVM and all the associated classes including sun/jdbc/odbc/JdbcOdbcDriver. But when you use this Java COM object (which I am not familiar with), if it doesn't find that class then it must be using the Microsoft VM, which naturally doesn't include that class you are having a problem with.

We upgraded to OS 10.5.8 and can't load thumb drive data back on

We backed up the MacBook onto a thumb drive, reinstalled Leopard, and now can't put the data back on the computer.
Any suggestions.

It is a friend's computer - an iBook (not duel processor) but she upgraded it last year to 10.5.1 and then Safari stopped working and the Genius bar said to reinstall Leopard. So we backed up her computer on a thumb drive and did a clean install of OS 10.5.1 and eventhing is fine - Safari works etc. however we can't put her data back on the computer?? I don't know what to do - I just know a little more than she does

Fglrx: How to load intel driver with various options, e.g. AccelMethod

Hi,
When using fglrx and pxpress on a system with hybrid graphics, how can options be set for the intel device?
Normally in the "xorg.conf" I could just put something like
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "sna"
EndSection
But with fglrx installed the xorg.conf looks like
Section "ServerLayout"
Identifier "Radeon Layout"
Screen 0 "aticonfig-Screen[0]-0" 0 0
EndSection
Section "Monitor"
Identifier "aticonfig-Monitor[0]-0"
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"
EndSection
Section "Device"
Identifier "aticonfig-Device[0]-0"
Driver "fglrx"
BusID "PCI:6:0:0"
EndSection
Section "Screen"
Identifier "aticonfig-Screen[0]-0"
Device "aticonfig-Device[0]-0"
Monitor "aticonfig-Monitor[0]-0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection
EndSection
(Adding an intel device section in here would cause major problems(I get segfaults). I guess because both fglrx/pxpress and xorg try to launch the i915 driver)
So how can I configure options for the intel driver?
Why do I want to do this?
Well aside from the ability to tweak the integrated GPU performance in the usual manner, I have a bug that occurs when UXA is used as the accleration method, but not when SNA is used for the intel driver (even before fglrx is installed on the system). Without fglrx SNA is the default anyway, but fglrx for some reason likes to use UXA.

Hi, thanks for the new link. Yes, this is completely relevant, but unfortunately it's incomplete & didn't work for me. Please pass this along to the documentation team. Referring to the document, here are the steps I followed:
A) Starting at section "Restore your computer when Windows 8 cannot start normally" ...
B) I turned the laptop on & pressed F11 : "System Recovery"
C) Spinning dots never end, just like during normal start-up, as I reported in original post
D) -> Document should mention the option of booting from Windows 8 installation DVD
E) Booting from Windows 8 DVD, I was able to reach step 7 : "On the Advanced options screen, click System Restore ."
F) I was unable to reach step 8 in the section : "Click Windows 8 as the target operating system." b/c I need to load the Intel storage driver for the RAID array that's configured in the BIOS, so that System Restore can see my hard drive.
How can I load that driver??
Thanks,
Brad
