Java.lang.ClassNotFoundException: org.gjt.mm.mysql.Driver...the same old pr
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>\lib
<java_home>\jre\lib\ext
my calsspath looks something like this
.;C:\Programme\QuickTime\QTSystem\QTJava.zip;C:\Programme\"Apache Software Foundation"\"Tomcat 5.5"\common\lib\mysql-connector-java-5.0.6-bin.jar;C:\Programme\"Apache Software Foundation"\"Tomcat 5.5"\webapps\axis\WEB-INF\lib\mysql-connector-java-5.0.6-bin.jar;C:\Programme\"Apache Software Foundation"\"Tomcat 5.5"\common\lib\servlet-api.jar;C:\Programme\"Apache Software Foundation"\"Tomcat 5.5"\common\lib\jsp-api.jar;C:\Programme\Java\jdk1.5.0_05\jre\lib\ext\mysql-connector-java-5.0.6-bin.jar;C:\Programme\Apache Software Foundation\Tomcat 5.5\webapps\axis\WEB-INF;C:\Programme\Apache Software Foundation\Tomcat 5.5\webapps\axis\WEB-INF\lib\activation.jar;C:\Programme\Apache Software Foundation\Tomcat 5.5\webapps\axis\WEB-INF\lib\axis.jar;C:\Programme\Apache Software Foundation\Tomcat 5.5\webapps\axis\WEB-INF\lib\axis-ant.jar;C:\Programme\Apache Software Foundation\Tomcat 5.5\webapps\axis\WEB-INF\lib\commons-discovery-0.2.jar;C:\Programme\Apache Software Foundation\Tomcat 5.5\webapps\axis\WEB-INF\lib\commons-logging-1.0.4.jar;C:\Programme\Apache Software Foundation\Tomcat 5.5\webapps\axis\WEB-INF\lib\jaxrpc.jar;C:\Programme\Apache Software Foundation\Tomcat 5.5\webapps\axis\WEB-INF\lib\log4j-1.2.8.jar;C:\Programme\Apache Software Foundation\Tomcat 5.5\webapps\axis\WEB-INF\lib\mail.jar;C:\Programme\Apache Software Foundation\Tomcat 5.5\webapps\axis\WEB-INF\lib\saaj.jar;C:\Programme\Apache Software Foundation\Tomcat 5.5\webapps\axis\WEB-INF\lib\wsdl4j-1.5.1.jar;C:\Programme\Apache Software Foundation\Tomcat 5.5\webapps\axis\WEB-INF\lib\mysql-connector-java-5.0.6-bin.jar
which is basically all the jar files in the web-inf\lib folder and references to all the copies of driver as mentioned before
these are results of a lot of desperatio but still the code which i run....
package mypackage;
import java.sql.*;
public class JDBCConnector
public static void main(String[] arg) throws Exception
System.out.println("Initiating Database Mysql Connection");
//try {
Statement stmt;

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

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!"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 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
sandroNo 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... -

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.

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. -

However I would suggest that you would have more luck at the other end of a google search on the error message.

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. Thanksweb-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.

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. -

Truncated. see log file for complete stacktraceDid you read this part there:
There is a second possible issue that is specific to the commons-logging and related libraries when used with Integrated WLS and the configuration (which includes ADF) out-of-the-box. Because the commons-logging.jar is apparently in the system classpath, due to the way Java classloader delegation works, any log4j classes at the web application level are not visible to the logger factory by default. As long as this is the case, you may need to add the following to your web-application's WEB-INF/weblogic.xml:
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
What this does is tell the WLS JSP servlet to let web application classes override classes found in the system classloader. Standard Java classloader delegation gives the highest priority to the system classes. -

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

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.

Help!
I've created a simple program that should connect to a client of mine using jdbc. I was given the driver class which I have imported and added to my build path. I deploy the application and it errors saying it cannot find the class. Here is the code:
public void wdDoInit()
//@@begin wdDoInit()
IWDMessageManager mm = wdThis.wdGetAPI().getComponent().getMessageManager();
String host = "host";
int port = 1433;
String SID = "hostsid";
String user = "username";
String pass = "pwd";
String driver_class = "net.sourceforge.jtds.jdbc.Driver";
String access = "jdbc:jtds:sqlserver://" + host + ":1433" + "/" + SID;
Connection con;
try
try
Driver driver = (Driver)Class.forName(driver_class).newInstance();
} catch (Exception e)
mm.reportWarning("msg = " + e.toString());
con = DriverManager.getConnection(access, user, pass);
} catch (SQLException e)
mm.reportWarning("Error: " + e.getMessage());Hi Steve,
Put jar file with JDBC driver to lib folder under your WD project and it will be included to wda and ear files.
BTW, may be it is beeter to register driver and datasource instead of using direct connect to DB? See how to register data source http://help.sap.com/saphelp_nw04/helpdata/en/b0/6e62f30cbe9e44977c78dbdc7a6b27/frameset.htm
