Ok, sorry if this question is stupid. I followed this tutorial: http://www.youtube.com/watch?v=E30_-pQGQXs. Now that I have it compiling in Eclipse, when I upload it to a remote server, how do I get it to work with the jdbc library?
If I try to execute Main.class on a remote server, I get
Exception in thread "main" java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
How do I include the jar or get rid of this error?
You have to make sure to include the mysql JDBC driver in the classpath on the remote server.
Some app servers have a specific folder to place 3rd party files that get included in the classpath.
Are you using an app server or is this a custom application?

I am having a problem where the Eclipse IDE does not recognize the jdbc driver in the .jar file. I have already tried putting it in the build path from WEB-INF/Lib and also the build folder. I have already added the Class.forname in my project to register the driver.
This is my url to my database in mysql: "jbdc:mysql://localhost:3306/loginDB".
I am using Tomcat v9.0 server.
I'm using 5.1.49 driver version for the .jar file.
The following link will bring you to my github, where my code is for my project.
https://github.com/shari002/files/tree/master/MyResgistrationProjects
This shows how I'm registering for driver to work.
You have a typo in your connection string.
jbdc:mysql://localhost:3306/loginDB
It should be jdbc.
I have created a jsp servlet application through netbeans which connect to mysql database and local server and it is working properly. Mysql connector jar file is in the lib folder. But after deploying in to mochar server (private jvm) it is showing
class not found expception Class.forName("mysql.jdbc.Driver")
How to resolve it?
Please make sure mysql connector jar is present in the tomcat lib folder.
(tomcat-home)/common/lib in case of tomcat5 and in (tomcat-home)/lib in case of tomcat7
I'm running a JBoss server (inside Eclipse), with some Hibernate mixed in. I installed Oracle's ojdbc drivers from here:
Oracle Database 11g Release 2 JDBC Drivers
I specifically downloaded the file: ojdbc6dms_g.jar, which according to the site contains instrumentation to support DMS. However when I startup my AS server, I get the following:
Caused by: java.lang.ClassNotFoundException: oracle.dms.console.DMSConsole from [Module
"com.oracle:main" from local module loader #485fcf29 (roots: /usr/local/jboss-7.1.1-
final/modules)]
when the server is trying to get a new hibernate ejb exception.
I checked Oracle's jar file and sure enough it doesn't contain the class oracle.dms.console.DMSConsole, although from the notes on Oracle's site about the jar file, it seems like the jar file should contain the DMS classes.
Can anyone point me to the correct jar file? And when I do get the right file, where should this file be installed to, particularly with regards to Eclipse and JBoss?
Update: Just found another question asking the same thing here on SO.
The missing classes are indeed in dms.jar. But as I've seen asked elsewhere finding the dms.jar file is not easy. You won't find dms.jar at Oracle Database 11g Release 2 JDBC Drivers because as noted by Oracle: dms.jar is not shipped as part of the RDBMS product. It is only available as part of the Oracle Application Server product.
I hopped onto our server and grabbed the jar file from our Oracle installation directory. We have 11g installed. With 11g you should be able to find the file here:
$ORACLE_HOME/oc4j/lib/dms.jar
I got the same error for different reason and yes it was due to missing dms.jar file. I just had to find where dms.jar file was on our Oracle Application server (Release 12.2.3) and assigned it to the CLASSPATH. And it worked. Thanks for the pointing to the missing .jar file.
Out .jar file was in $ORACLE_HOME/lib/ folder. Changed the path value as :
CLASSPATH=$CLASSPATH:$ORACLE_HOME/lib/dms.jar and it started working.
Fyi..if it helps anyone i was trying to load BI/XML publisher DATA TEMPLATE using XDOLoader utility when i got this error.

i too face this problem but when i removed all database related jars and added ojdbc6 (or ojdbc7) jar then application working fine. more details please see below link.

I've been trying to create an installer for a while now, and everything seems to work except adding external .jar files. My application imports the com.mysql.jdbc.Driver, in order to connect to the inbuilt MySql DB, But whenever I try to start the program via launcher (after installing), exceptions are thrown stating the mysql connector driver cannot be found. Would be glad if anyone could tell me the most straight-forward way to include external .jars with installer4j
Just solved the problem. It seems that external .jars need to be added individually on Step 3 in the classpath
I am using BIRT that needs to connect to a database using integrated security via a jdbc driver. When my .jar file (imported into BIRT) tries to connect to the MSSQL database, I get the following error: The driver is not configured for an integrated authentication...
My conclusion is that BIRT dimply does not see the sqljdbc_auth.dll file.
How do I make BIRT see sqljdbc_auth.dll library, other than just putting it into the BIRT's root folder? Can I issue -djava.library.path = .... somewhere within BIRT RCP?
Thanks!!
Can you post the eclipse.ini? Any vm arguments should be put after the -vmargs option on a new line. See http://wiki.eclipse.org/Eclipse.ini.
