As this question never received an answer I'll post one here.
Instantiating directly in your code means to do this:
Class.forName("com.mysql.jdbc.Driver");
This will try to load the class manually and run its static initializer. The message "java.lang.ClassNotFoundException: com.mysql.jdbc.Driver" means the class is not in your classpath, so if you get the same error, it means you have a missing JAR or it's not where it's supposed to be.
Since you mentioned using the Google Plugin for Eclipse I'll assume you're working with an App Engine project. For this type of project your JARs must be in WEB-INF/lib directory, so make sure the mysql-connector-java JAR is there.

I searched a lot but was unable to find any forum where I can see aforementioned error related to oracle 18.4.0.
I searched my whole server even unzipped all ojdbc*.jar but not found DMSConsole anywhere
I removed all previous jdbc jar drivers and downloaded latest ojdbc8-full.tar.gz driver form this LINK but nothing fixed the problem
Best Regards
What are you trying to do? If you are planning to use dms jar then you should use
ojdbc8dms.jar. Check out the question "What are the different JAR files on the 19.3 JDBC driver download page for?" in JDBC FAQ
You can get these jars from maven. Check out the blog for details. You can also download these from ojdbc8-debug.tar.gz from OTN. Make sure to have dms.jar in the classpath.
<groupId>com.oracle.database.jdbc</groupId>
<artifactId>ojdbc8dms</artifactId>
<version>19.6.0.0</version>
This can be solved by adding a correct dms.jar but when not detailled log is needed the following jars are the minimum to include
ojdbc8.jar
orai18n.jar

Thanks in advance.
Set 'client mode' if you write client, more
factory.setIntProperty(CommonConstants.WMQ_CONNECTION_MODE, CommonConstants.WMQ_CM_CLIENT);

Do you have JAAS configuration file? If you do, then you probably have old format of "initiate" section - com.sun.security.jgss.initiate, note that it's missing ".krb5". It should be com.sun.security.jgss.krb5.initiate.
Or maybe the path to configuration file is incorrect in your server startup command line.
We have a project made in netbeans 7.3 and are about to deploying this to a remote glassfish server, everything is configured and set up properly and the connection pools for our project are also generated in glassfish.
Currently we are getting this error when deploying to the remote server:

Error occurred during deployment: Exception while preparing the app :

Google wasn't very helpfull before, so hopefully you guys/girls can help me
Thanks in advance!
You may need a mysql / java connector.
You can find it there. Extract the mysql-connector-java .jar from the archive. Then place it into the glassfish external lib directory {INSTALL DIR}/glassfish/domains/domain1/lib/ext.
Restart your glassfish server.
There are more details on this answer. If that's not what you are looking for, or if it doesn't work, tell us. #+
Right, you just lack mysql lib, just find and download mysql-connector-java-5.x.x-bin.jar copy to E:\Projects\glassfish3.1.1\glassfish\lib then restart server and enjoy !!!
I am using jasper server CP 5.0.0. I have configured the data source properties like this
Set Data Source Type and Properties
Driver (required):com.mysql.jdbc.Driver
URL (required):jdbc:mysql://localhost:3306/jasperserver
The connection is failed when clicked on test connection
When I am running the report I am getting a error
Error Message

Error Message
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
Error Trace

I have been searching this for a long time with no success.
You should add mysql drivers jar file to the build path of your project.
