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

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.

Here is my code
MQQueueconnectionFactory factory=new MQQueueconnectionFactory();
factory.setHostName(HostName);
factory.setTransportType(1);
factory.setPort(1414);
factory.setChannel(ChannelName);
factory.setQueueManager(Queuemanagername);
connection=factory.createQueueConnection();
connection.start();
Error
"Caused by: com.ibm.mq.jmqi.JmqiException: CC=2;RC=2495;AMQ8568: The native JNI library 'mqjbnd' was not found. [3=mqjbnd]

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

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'm running a couple of SQL connections from a Job. They are all working with the sqljdbc4.jar, but when I run them with MS SQL Server Native (which was by default) instead of MS SQL Server - they fail with this error:
Error connecting to database [xxx_zxxxx] : org.pentaho.di.core.exception.KettleDatabaseException:
Error occured while trying to connect to the database
Error connecting to database: (using class com.microsoft.sqlserver.jdbc.SQLServerDriver)
Java Runtime Environment (JRE) version 1.7 is not supported by this driver. Use the sqljdbc4.jar class library, which provides support for JDBC 4.0.

.................
Caused by: org.pentaho.di.core.exception.KettleDatabaseException:
Can this be caused by the new JDK_1.8 I've installed? How to resolve this issue?
Thank you.
I found a work-around solution that worked just fine in my case. Just remove the sqljdbc.jar and leave only sqljdbc4.jar in my file system. Also added only sqljdbc4.jar to the System variables > path

org.hibernate.SessionException: Error! Please, check your JDBC/JDNI Configurations and Database Server avaliability. Could not open or put a Hibernate Session in ValueStack: JDBC Driver class not found: com.mysql.jdbc.driver
You have wrong driver class configured. The correct class name com.mysql.jdbc.Driver. See the example of usage here.
I am making a simple mapping program in hibernate.
I am facing an error:
JDBC Driver class not found: com.mysql.jdbc.Driver
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
It gives an error on this line:
Session session = HibernateUtil.getSessionFactory().openSession();
hibernate.cfg.xml is correct. In the same configration other program are run. but this program give me error.
What is the reason that it throws this error?
You need to get a MySQL driver and put it on your classpath.
A commonly-used driver is MySQL Connector/J. It can be found here. Extract the package and make the jar available to your application.
