Ready message received from Oc4jNotifier.
Embedded OC4J startup time: 29125 ms.

I did what Manu suggested with no success. Alternatively, I registered the driver jar with embedded OC4J preferences > global > libraries. Still does not work. Please, note, that when I run JUnit tests against my BC4J application modules with JDBC URL as connection type, everything works just fine. The problem comes while running the JSF application when the application module is using JDBC DataSource as connection type.

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.

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

mysql -u root -h localhost -p
mysql> use javatest
Database changed
mysql> select * from testdata;
| id | foo | bar |
| 1 | hello | 12345 |
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.
Good luck - MOD

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)}";Thanks

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?

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.

[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...

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.
bye

No, 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.

Com.mysql.jdbc.ResultSetImpl@55a338 (error)

I am getting this error the when i want to display the table contents of a database in Mysql..In the code i am using 2 recordset is that creating a problem..and it shows this error the number of times equal to the records present in recordset of a particular query..!!

1. It's just localy - no internet
2. Connection is continous.
3. hmm what is the suitable fashion [ sorry for my ignorance ] I got this:
com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.from the console after I put in the code this:
   public void connector(){
           try
               String userName = "root";
               String password = "";
               String url = "jdbc:mysql://localhost/log";
               Class.forName ("com.mysql.jdbc.Driver").newInstance ();
               conn = DriverManager.getConnection (url, userName, password);
               System.out.println ("Database connection established");
               System.out.println(conn);
           *catch (Exception w)*
               *System.err.println ("Cannot connect to database server " +w);*
              *// return false;*
    }thought is suitable = )

IDM 8.0 would not pick up MySQL jdbc driver.

I am trying to create database table using "create new resources" in IDM.
With orcale, I have no issue. I copy a jdbc driver to C:\idm8\WEB-INF\lib and rename it
oraclejdbc.jar.
However, after I copyed mysql-connector-java-5.1.5-bin.jar ( which works with netbean and MySQL server on
my PC) into the same C:\idm8\WEB-INF\lib directory ( and i tried rename it mysqljdbc.jar too),
Database Type: MySQL
JDBC Driver: com.mysql.jdbc.Driver
JDBC URL TEmplate: jdbc:mysql://localhost:3306/test
Host: localhost
TCP Port: 3306
Database: test
I got an error:
XPRESS <invoke> exception:
Can't call method getTableData on class com.waveset.ui.web.resources.wizard.DBTableUtil
==> com.waveset.util.WavesetException: ==> java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/test
Then I tried the case where I replace localhost with IP Address and th ecase I use Fully qulified
PC name, I got the same error.
I know that the driver works because it is being used in NetBeans6.1
I also tried mysql-connector-java-5.1.6-bin.jar with the same results.
Does anyone have any ideas?
Thanks!

Could your issue be with this line here:
JDBC URL Template: jdbc:mysql://localhost:3306/testI believe it should be something like this: (As chapo pointed out)
JDBC URL template: jdbc:mysql://%h:%p/%dThe template is exactly that, a template.. The values are filled in by the next three entries

JDBC Driver error when working in command prompt.

I have a swing program that connects to MySql Database. When run within the Netbeans IDE, there are no errors. But when I run through the command prompt, I get the User Interface screen but does not connect to the database. I have also added the "mysql-connector-java-5.1.6-bin.jar" file in the jdk folder.
The error I get is "com.mysql.jdbc.Driver" which is the driver I have been using in Netbeans. How do I get over this problem?

The error I get is "com.mysql.jdbc.Driver" which is the driver I have been using in Netbeans. How do I get over this problem?1. Fix your GUI so it reports the problem, rather than relying on command line output.
2. Fix your class path which doesn't have the driver jar.
3. There is a JDBC forum.
