i can't connect from pentaho to mysql
Error connecting to database [mysql - simpeg] :org.pentaho.di.core.exception.KettleDatabaseException:

i already add at \pdi-ce-8.2.0.0-342 PENTAHO\data-integration\lib
com.mysql.jdbc_5.1.5.jar
and i restart my PDI, when i try again, the problem is same.
please help me. Thanks
Pentaho Data Integration uses mysql-connector-java-5.x.xx-bin.jar to connect MySQL for example mysql-connector-java-5.1.49-bin.jar and you can download MySQL driver from here also you can find PDI's JDBC Drivers Reference from here
I download last version of MySQL jdbc connector (mysql-connector-java-8.0.13) and I put it in the following folders:
C:\Users\maria\Desktop\report-designer\report-designer\lib
and
C:\Users\maria\Desktop\report-designer\report-designer\lib\jdbc
And it shows me the following error:
Driver class 'org.gjt.mm.mysql.Driver' could not be found, make sure the 'MySQL' driver (jar file) is installed.
org.gjt.mm.mysql.Driver
org.pentaho.di.core.exception.KettleDatabaseException:
Error occurred while trying to connect to the database
While, when I introduced the old version file (mysql-connector-java-5.1.34-bin) at the same folders as said before (above). Pentaho shows me the following error:
Error connecting to database: (using class org.gjt.mm.mysql.Driver)
Could not create connection to database server.
org.pentaho.di.core.exception.KettleDatabaseException:
Error occurred while trying to connect to the database
can someone help me?
Thank you!
Finally I manage to solve the error.
I put my jdbc connector (mysql-connector-java-8.0.13) into the following folder:
C:\Users\maria\Desktop\report-designer\report-designer\lib an
And I change the name of my MySQL DB.
Thank you
Stop Report Designer
Remove it from the 'C:\Users\maria\Desktop\report-designer\report-designer\lib\jdbc' directory
Restart Report designer
You can only have one jdbc driver in the lib directory for the db. So when you add the 5.1.34 driver, you are adding a second MySQL driver, causing that second error.
I have set up a database with MySql.
I want to connect to it from Eclipse.
I followed the same steps as mentioned in this link:
https://www.zkoss.org/wiki/Setup_MySQL_DB_in_Eclipse
So I am using this library for the driver:
mysql-connector-java-5.1.45
whhich I think is correct
The name of my database is "test" and the port used by MySql is 3306.
This is my configuration:
But when I test the connection it's giving me an error message :
"An internal error occurred during: "Ping server job". java/sql/SQLException"
I have looked more in details in the error log and I see error like this:
java.lang.NoClassDefFoundError: java/sql/Connection
I have turned off my firewall just to check, but it does not solve the issue.
Can someone tell me what I should check?
Thanks
I use Java version 1.7.0_80 and Eclipse Mars.2 Release (4.5.2).
I gave up and used MysQL Workbench which meets my needs.
I have a Windows service (using .NET framework 4.5) installed on a Windows 2012 R2 machine. I have MySQL connector 6.9.7 and MySQL 5.6.25
When my service is started I am getting following error.
Authentication to host 'xxx.xx.x.xx' for user 'yyyyy' using method 'mysql_native_password' failed with message: Reading from the stream has failed. ---> MySql.Data.MySqlClient.MySqlException (0x80004005): Reading from the stream has failed. ---> System.IO.EndOfStreamException: Attempted to read past the end of the stream.
or sometimes:
Unable to connect to any of the specified MySQL hosts.
If I restart the service in a while all seems to work properly. Any idea what the problem is?
Migrating OP's solution from the question to an answer:
After further investigation we have found that our database version was 5.6.25. We have tried same connectivity with our old db 5.5.16 and we didn't face the same issue, so it looks like issue is the database itself. Our new database is installed on a Linux machine.
