I am getting the below error when i am trying to connect to my database.

Information :
Platform : RHEL 5
Java : jdk1.6.0_45
jdbc connector : mysql-connector-java-5.1.26-bin.jar
Sever: Tomcat 6
I have placed the jdbc connector inside usr/share/java/ Directory.
and my program to test the connection is placed in the root folder.
I have set the CLASSPATH to point to the connector using EXPORT command.
and I am using javac filename.java command to compile & java filename to run it.
A JDBC driver doesn't need to be installed or configured. You download the jar, add it to the runtime classpath of your application, and you're done:
java -cp someJar.jar:someDirectory:theMySQLJdbcDriver.jar com.foo.bar.Main
I have installed the old version of mysql connector which was compatible with RHEL5
and now its working fine.
Thanks !!

I am running Squirrel-SQL version 3.9.0 using JDK 10 on MS-Windows 10. I have configured the Microsoft SQL server JDBC driver sqljdbc42.jar along with it's native DDLs to enable native kerberos authentication. But when I try to connect to my database, I get the message JDBC Driver class not found class java.lang.ClassNotFoundException: javax.xml.bind.DatatypeConverter. How do you fix this issue?
I was able to fix this issue by placing the jaxb-api-2.3.0.jar into squirrel-sql-3.9.0/lib folder and restarting the application.
had same problem . i updgrated everything to last version of Squirel 4.5.1 (janvier 2023) & last JDK 19 & last driver SqlServer , but problem continue to occur
i found another post on StackOverflow who asked which repository had this jaxb jar
How do I resolve Could not find artifact javax.xml.bind:jaxb-api:pom:2.3.0-b161121.1438 in central (https://repo1.maven.org/maven2)?
this is the link to jaxb jar, i added it in lib/ under squirell directory , then it worked
https://maven.java.net/#nexus-search;gav~javax.xml.bind~jaxb-api~2.3.0-b161121.1438~~
Currently I'm looking in the Force.com Canvas Developer's Guide at "Chapter 3: Quick Start--Advanced".
I've successfully cloned SalesforceCanvasFrameworkSDK from GitHub, and am now trying to Run the Web App Locally.
The build is successful and keystore has been created. However, when I execute target\bin\webapp.bat, I get the following error:
Error: Could not find or load main class Main
Find that the main class seems to be in C:\SalesforceCanvasFrameworkSDK\target\classes, I modified the .bat file, to include this in the CLASSPATH:

If it is relevant:
OS: Windows 7
Java: 1.8.0_25
Maven: 3.2.2
Any help to resolve this will be appreciated!
I was able to fix this as follows on MacOS Sierra 10.13.6
The problem does seem to be with Java 8, so if you can start the whole installation with Java 7, you'll save a lot of time. In my case, I had already installed Java 8, so I had to do the following:
1- Install java 7 from: https://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html . You have to create an Oracle account, it's free.
2- Confirm both versions of java are runningv
Pablos-MacBook-Pro:SalesforceCanvasFrameworkSDK pabloalvarez$ /usr/libexec/java_home -V
Matching Java Virtual Machines (2):
1.8.0_191, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_191.jdk/Contents/Home
1.7.0_80, x86_64: "Java SE 7" /Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home
3- Then
export JAVA_HOME=`/usr/libexec/java_home -v 1.7.0_80`
export JAVACMD=`/usr/libexec/java_home -v 1.7.0_80`
Confirm that Java 7 is the default version now
Pablos-MacBook-Pro:SalesforceCanvasFrameworkSDK pabloalvarez$ java -version
java version "1.7.0_80"
Java(TM) SE Runtime Environment (build 1.7.0_80-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)
5- Then
export JAVACMD=/usr/bin/java
6- Finally
Pablos-MacBook-Pro:SalesforceCanvasFrameworkSDK pabloalvarez$ sh target/bin/webapp

Good luck!
I would like to use springMVC and JPA (using hibernate) on my tomcat 7 server (running locally on my Mac).
I was able to set up everything successfully with an embedded H2 database.
Now I switched to mysql and am getting the following error
java.lang.ClassNotFoundException: "com.mysql.jdbc.Driver"
org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1711)
org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1556)
This suggests tomcat is having trouble finding the mysql-connector for java.
There are a multitude of tutorials on how to add the connector to $CATALINA_HOME/lib.
After trying to use a maven dependency for my project, I followed the advice and copied the .jar file into the lib directory:
$ ls $CATALINA_HOME/lib/mysql*.jar
/Users/david/Applications/tomcat/lib/mysql-connector-java-5.1.20-bin.jar
I have read and execute permissions on the directory and file.
At the moment I can't figure out how to make tomcat aware of the jar. The folder is included in
$CATALINA_HOME/conf/catalina.properties
and I have restarted the server multiple times.
Thanks for you help.
Normally, the output of a CNFE is as follows:
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
whereas your error message shows
java.lang.ClassNotFoundException: "com.mysql.jdbc.Driver"
I think you've still got quotes around the driver class name in your config.
Whenever I try (My)SQL queries on the sever (the server is in debug mode in Eclipse) I get this error:
SEVERE: Cannot load JDBC driver class 'com.mysql.jdbc.Driver'
Now I can't recall how I got this detail, but I suspect that the following info is relevant:
with %MyWorkspace% being some path like x:\some_path, this path:
%MyWorkspace%\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\rewardy\WEB-INF\lib
contains the mysql-connector-java-5.1.13-bin.jar file, that if I'm not wrong has the com.mysql.jdbc.Driver class that it looks for (am I right ?...)
I use this config: Win7 x64, Eclipse Helios Service Release 2, WAMP Server and Tomcat 6.0.26.
You should have to add location of mysql-connector-java-5.1.13-bin.jar via project properties + Java Build Path + Add External Jars (Eclipse IDE)
have you mysql-connector-java-5.1.13-bin.jar in classpath or in libs/ on tomcat ? – triclosan
Thanks #triclosan, I put it in Tomcat/lib and it works now!
I wrote java class to connect mysql database and insert data to database on my centos installed pc.(this java file called by asterisk program using AGI). but I got below exception at runtime.
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
How could I solve this ?
Ok. I solved my question. when I run the asterisk program with AGI server, I added mysql connector classpath as below.
java -classpath asterisk-java-0.3.jar:mysql-connector-java-5.1.18-bin.jar:. org.asteriskjava.fastagi.DefaultAgiServer
you need this jar file: mysql-connector-java-{version}.jar
e.g.
http://findjar.com/jar/mysql/mysql-connector-java/5.1.9/mysql-connector-java-5.1.9.jar.html
