Driver class 'org.gjt.mm.mysql.Driver' not Found JSP

OS ->Windows XP Pro
Tomcat version ->4.0.1
jdk version -> 1.3.1
database -> mysql
Classpath = .;C:\jakarta-tomcat-4.0.1\common\lib\servlet.jar;C:\jakarta-tomcat-4.0.1\common\lib\mm.mysql.jdbc-1.2c\mysql_uncomp.jar;
I am trying to run a function in a javabean to startup up a connection to a database. Code as follows...
public void connect() throws ClassNotFoundException,

try {
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
con = DriverManager.getConnection(

} catch (ClassNotFoundException cnfe) {
error = "ClassNotFoundException: Could not locate DB driver.";
throw new ClassNotFoundException(error);
} catch (SQLException cnfe) {
error = "SQLException: Could not connect to database.";
throw new SQLException(error);
} catch (Exception e) {
error = "Exception: An unknown error occurred while connecting " +
"to database.";
throw new Exception(error);
I call it from my jsp page code as follows.. connect in bold
<%@ page language="java"

The name of the bean is correct and so is the package it is stored under. I tried it in the bean and got "ClassNotFoundException" Could not locate DB driver". I tried it with DBtags and got
Driver class 'org.gjt.mm.mysql.Driver' not Found
any help would be really appreciated.

When using any 3rd party library with tomcat. the jar file of that library has to be put in the WEB-INF/lib directory of your application. Then only tomcat will find it.
So the my-sql driver would have come in a jar file. just put that jar file in the WEB-INF/lib directory.
After that things should work. If they don't please post again.
hope this helps.

Abhishek.

Cannot load JDBC driver class 'org.gjt.mm.mysql.Driver'

Hi,
I'm trying to run my web app and connect to a MySQL database but keep getting this error:
org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot load JDBC driver class 'org.gjt.mm.mysql.Driver'
any ideas?
Thanks!

Lookup the stacktrace and find the root cause of the exception.
My cents on a ClassNotFoundException which is rather self-explaining.
By the way, the mentioned driver class name is a very old driver. You shouldn't be using that anymore. Surf to the MySQL homepage and download the most recent Connector/J JDBC driver for your database version. Documentation is also available over there.

Org.gjt.mm.mysql.Driver not found help!!

hi all
it's the first time for me working with MySql, and when i try to connect to the db, i have the following exception:
java.lang.ClassNotFoundException: org.gjt.mm.mysql.Driver
i know that i shall download it from Mysql site, but i don't know WHERE to put it
i'm using forte 3.0 - jdk 1.4.0 on Win2K
please help me!
thanx
sandro

No problem,
in general you should modify the CLASSPATH of your JDK to point to the jar-driver-file, e.g. (on unix): CLASSPATH = "someDirectory"\driverFIle.jar:$CLASSPATH
and then: export CLASSPATH. That should solve your problem. if using windows: Just take a look at systemControlCenter. There it's possible to modify the CLASSPAT-environment.
So far...

Hi,
I am a new user in this forum..
I have just installed tomcat and mysql and jdbc fresh on my new system..
first of all here is what i have done...
i have installed mysql integrated in xampp at c:\xampp\mysql
i have installed my tomcat at C:\Programme\Apache Software Foundation\Tomcat 5.5
i have put jdbc <dirver>.jar file copied in all sorts of directories like ....
<tomcat_home>\common\lib
<tomcat_home>\webapps\axis\WEB-INF\lib\ext

<java_home>\jre\lib\ext
my calsspath looks something like this

Including org.gjt.mm.mysql.Driver with my application

So, lets say I have a Java program that connects to an SQL server and it runs fine on my machine. I have all the nessicarry classpath's and Connector/J properly installed. But, when I run it on a client machine I get:
java.lang.ClassNotFoundException: org.gjt.mm.mysql.DriverNow, I can solve this issue by putting the Connector/J onto their computer but, I'm wondering if there's a way to package the application and the driver so that anyone can run it without having to install Connector/J manually.
Any help would be much appreciated.
Thanks!

That's the old, deprecated JDBC driver class name.

Thanks!"install" it manually? Nobody "installs" a 3rd party JAR. These aren't quite DLLs.
I'll assume your app is a desktop deployment. Package it into an executable JAR, add the Connector/J JAR to the Classpath in the manifest, and zip that JAR up with the Connector/J JAR. Your users will just unzip the ZIP file and execute the JAR.

Org.gjt.mm.mysql.Driver

I want to send a WAR file of my web applications to my clients. The application consiting of servlets and jsps connects to a database and requires org.gjt.mm.mysql.Driver how do i incorperate the .jar inside the WAR so my client doesn't have to fiddle with dropping jars in tomcats lib directory? I've tried including the org.gjt.mm.mysql.Driver driver jar inside the war WEB-INF/lib but it still says it cant find the driver?

If you have set up connection pooling within Tomcat, there is no way around it. The connection pooling is controlled by Tomcat, so it requires the driver file in [TOMCAT]/common/lib.
The only way to have a completely independant WAR file would be to handle all the database connections and connection pooling yourself within the web application.

Help. JDBCRealm error -- org.gjt.mm.mysql.Driver not found

Hi All,
I tried to setup JDBCRealm. After I config. to JDBCRealm and restart tomcat. I got this error:
java.sql.SQLException: org.git.mm.mysql.Driver error.
Can someone help. Thanks

web-inf/lib is not sufficient in this case, as the Tomcat engine needs access to the driver - not just your application.
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/realm-howto.html#JDBCRealm
You need to
Place a copy of the JDBC driver you will be using inside the $CATALINA_HOME/server/lib directory (if you do not need it visible to web applications) or $CATALINA_HOME/common/lib (if it will be used both by Tomcat 4 and by your apps).
Cheers.

Java.lang.ClassNotFoundException: org.gjt.mm.mysql.Driver when using RMI

I am trying to connect to mysql Db through RMI but i am getting this exception.
When trying to connect to db through a normal class implementation without RMI it is connected succesfully.
What is causing the problem????
Thanks in advace

CLASSPATH, man. The RMI server needs to have the MySQL driver JAR in its CLASSPATH.
That's usually what that exception means.

Org.gjt.mm.mysql.Driver under tomcat?

hi all
anybody knows where to put this driver under tomcat in order to let my servlet connect to a MySql db?
thanx all
sandro

sandro
Put the driver on "lib/common/" directory of Tomcat, and since lib is directly located by tomcat when you restart it. You must have to restart the tomcat after copying the file. The folder path may be "/var/tomcat/lib/commomn/" and may vary during installation.
Cheers

Org.apache.struts.action.ActionServlet not found in web-application

Dear All,
I am new to ADF environment. I tried to create a simple page to show the records from
a table . I followed the sample application which is available in "Building Oracle ADF Applications: Workshop".
When i run my action from Struts Page Flow. It is giving error like
500 Internal Server Error
Servlet error: Error instantiating servlet 'action'. Servlet class org.apache.struts.action.ActionServlet not found in web-application EmpMaintanance-ViewController-webapp
anybody can suggest me What i missed?
Thanks in advance...

Hi,
you need to register libraries with th OC4J configuration files. However, you can also deploy the Struts library with you application (see OC4J documentation which is accessible on OTN via Oracle As documentation), in which case they are available from the application classpath

Record drive/partition "500G Ext HD Western Digital" not found!

I don't know why I'm getting this message when I open any songs I've recorded in Logic Express. It just started doing this today. Here is the message:{Record drive/partition “500G Ext HD Western Digital” not found!}
I do not get this message when I open and work on songs I've recorded in Garageband.
The 500G Ext HD is my external hard drive.
Does anyone know what this means and how I can resolve it and get back to recording music??

Does the disk appear OK on your desktop?
When exactly do you get this message? When you double-click on a Logic file on your external drive? Or when you start a new project? Is your record path set properly in Logic?
First, as you may be nearing a hard disk problem, make sure that all essential files are backed up properly.
Then, open up your Disk Utility and run 'Verify Disk' and 'Repair permissions' on your external drive. If you have a copy of Disk warrior, even better.

Exception :Provider org.apache.xerces.jaxp.SAXParserFactoryImpl not found

Hi All,
I run my application on Redhat Linux 2.4.9-e.27smp using java appname. I'm using JDK1.4.2 and am not using any app server. The app seems to run just fine for a few hours and then I start getting Exception :Provider org.apache.xerces.jaxp.SAXParserFactoryImpl not found exception out of blue. I run the app with following parameters -
java -server -XX:+UseAdaptiveSizePolicy -Xverify:none -Xms512m -Xmx512m -XX:+UseParallelGC -XX:ParallelGCThreads=4
I suspect this has to do with garbage collection and can't replicate this on will. I wonder if anyone has come across similar issue and is able to point me to the right direction.
Thanks for any help,

Quick question. I am receiving the following error too:

I am getting this error intermitently. Do you have any idea why this would happen. I am using an add on to a program.
