Help with com.mysql.jdbc.Driver
Hi all
I am new to working with java. I am working off of my laptop (pc -vista) and
am trying to connect to a database on a server I have, mac osx 10.x.
First question: I would install com.mysql.jdbc.Driver on the same server as
the MySql server correct?
Second and more important question: I have multiple pages
printed out on installing this driver but I just cannot follow it. I am not
very good in terminal(mac) and the install seems terminal based.
Can someone please try to explain to me in laymen terms what needs to
be done?
thanks alot

I wanted to access a database that was on a totally different machine, with a java application.
is this not very doable - or realistic?
It's completely doable.
i found enviroment variables for CLASSPATH that are pointing inside 'jre1.6.0_07'
but i also have 'jdk1.6.0_07' - should the development kit be the one i use? - sorry
back to original question - so would i just move the .jar file into
\jre1.6.0_02\lib\ext\ or something of that sort
thanks alot
MarcusYes, you can move the jar into the ext directory if you wish. How are you running your java application? What are you typing/clicking on?

No suitable driver with com.mysql.jdbc.Driver
Ok. here's the issue. I have a windows box. (first problem) but let's pretend that it's ok. :) I installed Tomcat 4.1 installed J2SDK1.4.0
start serving pages GREAT!. I have Mysql working perfectly with PHP on this system. I JUST want to connect with JDBC :)
I've downloaded the MySQL Jdbc Connector/J 3.08 stable installed the .jar file in the $JAVA_HOME/jre/lib/ext as per the README
Now granted I am a little new to JSP. but I have checked over this again and again. used different code. connected as many ways as I can think of and I still get the same result.
Database Error :
No suitable driver
Please Try Some Other Time
So I figure it's a MYSQL issue. no I also went thru and did the Microsot connection to MS SQL 2000 with the same result.
Here's where the drivers are (tried using the other method for installing the MySQL connector as well, and my class path
Y:\j2sdk1.4.0\com\mysql\jdbc\Driver.class
com.mysql.jdbc.Driver.class
Y:\j2sdk1.4.0\org\gjt\mm\mysql\Driver.class

Just to show you mysql is Good. with localhost.
mysql -u root -h localhost -p
mysql> use javatest
Database changed
mysql> select * from testdata;
| id | foo | bar |

1 row in set (0.00 sec)
mysql>Nope, it's not a MySQL issue.
I'd recommend NOT putting the JDBC JAR file (or any others, except Sun-sanctioned extensions) in JAVA_HOME/jre/lib/ext.
JDBC JARs belong in TOMCAT_HOME/common/lib or in the WEB-INF/lib directory for your particular app. If you put them in the former, all apps running under Tomcat can have access to them. If you put them in the latter, only your app can see them.
After you've done that, do some reading about JNDI data sources under Tomcat:
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples-howto.html
That way you can get that connection code out of your JSPs and into the web.xml and <Context>, where it belongs. You'll be able to change data sources without rewriting your pages.

Help! JSP w/ struts can't find Class.forName("com.mysql.jdbc.Driver")
I think this is just a directory structure issue but I can't figure it out. I am writing a JSP / Struts / MYSQL web application which uses the mysql JDBC connector. The connector (mysql-connector-java-5.1.6-bin.jar) is in the referenced libraries. If I write the line of code:
Class.forName("com.mysql.jdbc.Driver");
To load up the driver, it works in JSP files in the folder /projectname/webroot/web-inf just fine and I can go on to execute MySQL queries. However, I need to load up the driver in an action (.java action) with the directory structure /projectname/src/action and it throws the exception "class not found", I believe, it can no longer seem to get to the driver. Can anyone tell me how to resolve this problem?
Thanks in advance, I hope this is the correct place (I have done my best to find the right one).

It has to be in CLASSPATH, and that isn't an environment variable.
If I write the line of code:
Class.forName("com.mysql.jdbc.Driver"); No, wrong.
The JAR file for the Driver class might go in the WEB-INF/lib of your web app. If you're using Tomcat 5.5.26, put it in common/lib.

Com.mysql.jdbc.driver and jdbc:odbc bridge driver
Hi All,
I want to update mysql database from data in hashtable. My application already uses JDBC:OBDC bridge driver for retrieving data from excel sheet and putting in hashtable.
For connecting to mysql i need to use com.mysql.jdbc.driver too in the same code.
How to do that?
my code uses.
Read(String strFilePath,String strFileName)
filepath = strFilePath;
filename = strFileName;
strDriver= "jdbc:odbc:Driver={MicroSoft Excel Driver (*.xls)}";ThanksPlease stay with one thread:

Error : class not found exception : com.mysql.jdbc.driver in Eclipse Tool
Hi
I have impoted project file in eclipse in new machine using option import from existing workbence . When i stat to debug this project ,
i am getting error as class not found exception : com.mysql.jdbc.driver . my project folder already consist of mysql .jar file in /web appls/web-inf folder.
Application is running successfully in other machine from where i took the application file. As this error appeared I also added jar file into project path as Project ---->properties-- build java path---libraries----add external jar file.
kindly hep me.Sounds like an eclipse question - not a JDBC one.
But since eclipse is telling you it can't find it then it means it is not in the eclipse path. So you must add it. (The fact that it is somewhere is irrelevant - all that matters is it is not in the class path.) -
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.

[Sun Studio 11] Classpath issue: com.mysql.jdbc.Driver not found
Greetings !!
I'm trying in an Applet to connect to a mysql database but the Applet fails everytime.
It works perfectly in console environnement with the same javaconnector.
I read this:
+Classpath. Specifies the path to the classes that the IDE uses. By default the IDE uses its internal class path, which includes all mounted filesystems and various directories in the IDE's installation and user directories. The IDE ignores your CLASSPATH environment variable. Click the ellipsis button to display a property editor in which you can change the class path settings.+
So my CLASSPATH environnement variable is passed by (as I redoubted) but I don't know why even specifying classpathes in Options/Building/Compiler Types/internal compilations/expert/class path the I got the same behaviour from the Applet... is there another way to specify that this Driver* is located in */usr/share/java/mysql-connector-java-5.1.7-bin.jar* ??
I also added the jar files in Options/IDE configuration/System/File System settings/java librairies but same behaviour again... but when compiling the output windows indicates that it has finished jdbc... that's all, the Applet still can't open a connexion with the mysql server...
Can somebody could explain to me how set up the IDE to use this javaconnector in order to connect to the mysql database ?
Thank you for your time...

CLASSPATH is "C:\JDK1.5\bin"
I have already downloaded "mysql-connector-java-5.0.5-bin.jar" and placed the "C:\JDK1.5\jre\lib\ext\" .
Still this problem persist.........plz guide me for the same.........
thanks in advance......What is <classname>? Is that the "ClassToRun" from my example?
If so, add the path to the "root" of the package hierarchy where your class can be found.
For example:
Your class is in C:\Bogus\Bogus1\com\mine\MyClass.class
And its package is com.mine
Then your command looks like this:
java -cp "C:\full\path\to\jarfile\mysql-connector-java-5.0.5-bin.jar;C:\Bogus\Bogus1" com.mine.MyClass
Or your class is in C:\Bogus\Bogus1\myjarfile.jar
Then your command looks like this:
java -cp "C:\full\path\to\jarfile\mysql-connector-java-5.0.5-bin.jar;C:\Bogus\Bogus1\myjarfile.jar" com.mine.MyClassEdit. Added jar info -
Java.lang.class not found exception: com.mysql.jdbc.Driver
Hi everyone,
I am using Jdk 1.5.0 , Connector/J 3.1 , Mysql 4.1.8 .
When i try to connect to mysql i got the subject mentioned error
i had alredy copied mysql-connector-java-3.1.8-bin-g.jar full path in my class path , butstill the same error is coming.
can any one suggest me the solution for this.
thanks in Advance.
byeNo, the "-g" version just means it has the debug flag turned on when they compile it.
Your problem is CLASSPATH and how to set it properly.
Use the -classpath option on java.exe when you run. Read the javadocs on the tools to find out how.

Using mysql jdbc driver leads to exception
I try to use com.mysql.jdbc.Driver with JDeveloper 9i business components. The following is the code I use to test if mysql driver works with business components:
package test;
import oracle.jbo.*;
import java.util.Hashtable;
import javax.naming.*;
public class Test {
public static void main(String[] args) {
final String amName = "test.TestModule";
final String voName = "test.TesttableView";
final String userName = "some_user";
final String password = "some_password";
final String connStr = "jdbc:mysql://localhost:3306/test";
System.setProperty("jdbc.drivers", "com.mysql.jdbc.Driver");
Hashtable env = new Hashtable(2);
env.put(Context.INITIAL_CONTEXT_FACTORY, JboContext.JBO_CONTEXT_FACTORY);
env.put(JboContext.DEPLOY_PLATFORM, JboContext.PLATFORM_LOCAL);
ApplicationModule appMod = null;
try {
javax.naming.Context ic = new InitialContext(env);
ApplicationModuleHome home = (ApplicationModuleHome)ic.lookup(amName);
appMod = home.create();
java.util.Properties props = new java.util.Properties();
props.put("user",userName);
props.put("password",password);
props.put("defaultRowPrefetch","15");
appMod.getTransaction().connect(connStr, props);
} catch(Exception e) {
e.printStackTrace();
ViewObject vo = appMod.createViewObject("vo", voName);
Row r = vo.first();
r.setAttribute("Testcolumn", "Some text");
System.out.println("vo before AppMod post " + r.getAttribute("Testcolumn"));
try {
appMod.getTransaction().commit();
System.out.println("Commit succeeded.");
} catch (oracle.jbo.JboException e) {
System.out.println("Commit failed. " + e);
r = vo.first();
System.out.println("vo after AppMod commit " + r.getAttribute("Testcolumn"));
Everything works fine until ViewObject.first() is called, then the following exception is thrown:

Difficulty Installing the MySQL JDBC Driver
I am trying to install mySQL JDBC driver "mysql-connector-java-2.0.14.tar.gz" to link up with the mySQL server on a Windows XP OS.
The error is:
Cannot find database driver classes
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
I have read the USAGE AND INSTALLATION in the README file, but it can not seem to find these drivers still. I added the location to my PATH variable in the environment variables, and set CLASSPATH= ... as well and still can not find them
Paths i added to PATH and CLASSPATH variables
C:\j2sdk1.4.0_01\mysqlconnector.tar
C:\j2sdk1.4.0_01\JDBC
I did both methods it suggested, within the JDBC folder are the com and org folders. Anyone offer some suggestions.
I know some smart person is going to say just use linux, but it is needed for my father and he can barely use MS Windows.
Cheers for any helpDear Java Newsgroup User
I would like to understand more around the Java and MySQLJDBC Configuration. Because I have some problem trying to install and Testing the MySQL JDBC Connector Driver.
I use Windows XP Professional.
I Downloaded and Intalled Sun One Studio to start learning JAVA and Features. This SDK Package make 3 Packages (directories):
Directory No1 C:\JSDK4\j2sdk1.4.1_02 (JAVA_HOME)
Directory No2 C:\JSDK4\s1studio (Source Examples ...)
Directory No3 C:\Archivos de programa\Java\j2re1.4.1_02 (Java R. Env.)
In the WINDOWS XP PANNEL CONTROL apper Java Plugins Control Pannel also
when I press or click this icon apper a Java Screen where i can see the following Configuration in the Advanced Option:
Java RuntTime Enviroment:
Use Java Plugin Default
JRE 1.4.1_02 in C:\Archivos de programa\Java\j2re1.4.1_02
SDK 1.4.1_02 in C:\JSDK4\j2sdk1.4.1_02
MySQL Driver Confiration and Version:
This is my Un-ziped MySQL JDBC connector Path:
C:\JSDK4\j2sdk1.4.1_02\mysql-connector-java-3.0.8-stable
Into mysql-connector-java-3.0.8-stable directory exist an directory called [testsuite] that have some jar, java and class files.
Testing MySQL JDBC Connecto Driver and Error Message:
When i try to run the BaseTestCase.class file the system give me the following ERROR Message:
