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.

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.

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.

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...

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.

Post the part of your code that loads the driver and connects. My guess is you are using a variable for the name of the driver and the variable has not been set to anything(intially set to null).

SOA WebLogic : Cannot load JDBC driver class

Hi, I'm new to this Oracle SOA World. Currently I'm trying to configure environment on my system. I found a very useful document to install all related SOA component to my system, the document name was 'Quick Start Guide for Oracle® SOA Suite 11gR1 (11.1.1.5.0)'. I did all the steps written in the document and have installed all the components successfully, component including Database, Jdevelper, WebLogic Server, RCU, SOA suite, service bus, all are installed successfully.
But when I'm trying to Configure Application Server (start -> Oracle SOA 11g-Home1), at one step 'Configure JDBC Component Schema' , here I'm getting this message

Hi:
try placing the jars that represent ur driver, here
For both Windows and Linux, you must perform the following steps:
Drop the vendor-specific driver JAR files to the user_projects/domains/soainfra/lib directory.
Drop the vendor-specific driver JAR files to the <Weblogic_Home>/server/lib.
Edit the classpath to include the vendor-specific jar file in <Weblogic_HOME>/common/bin/commEnv.sh
This info was copied, from here: http://docs.oracle.com/cd/E21764_01/integration.1111/e10231/adptr_db.htm#CHDBEJDC
Hope this helps
best

Cannot load JDBC driver class 'com.mysql.jdbc.Driver'

Hi,
At the moment I'm trying to get an example working. The error message I get is:
Unable to get connection, DataSource invalid: "org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot load JDBC driver class 'com.mysql.jdbc.Driver'"
The example I tried is http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html.
Configuration:
Wampserver 2.0 (Apache, MySQL, PHP for Windows XP), Tomcat 6.0 and jdk1.6.0_03.
The following files are installed in %CATALINA_HOME%/webabbs/
- Dbtest/test.jsp
- Dbtest/WEB-INF/web.xml
- Dbtest/WEB-INF/lib/standard.jar
- Dbtest/WEB-INF/lib/tomcat-dbcp.jar
- Dbtest/WEB-INF/lib/jstl.jar
Tia,
Abel.

Hi,
I added the jar file containing the requested class to my lib directory. So the current contents of that directory is:
The following files are installed in %CATALINA_HOME%/webabbs/
- Dbtest/test.jsp
- Dbtest/WEB-INF/web.xml
- Dbtest/WEB-INF/lib/standard.jar
- Dbtest/WEB-INF/lib/tomcat-dbcp.jar
- Dbtest/WEB-INF/lib/jstl.jar
- Dbtest/WEB-INF/lib/mysql-connector-java-5.1.5-bin.jar
More importantly, I started my Wamp server.
The example works as it should have. Thanks for the feedback.
Abel
