Mysql-connector-java Or Mysql-connector-j
Chrystal Dueno
So I replaced the mysql-connector-java file with an older version (8.0.15), but when I go to CF admin settings page and look at CF Server Java Class Path, it still lists the newer version (8.0.25). And I did confirm the location of the file. I have restarted CommandBox and even my laptop, just in case.
I am having problems with Glassfish 4.1 connecting to a mysql database. Ive checked that the database can be logged into with root and password. When the web app gets called Glassfish consistently says :
I have written a small app that needs to test if java can successfully connect to mysql before I can fault find any further. My question is how do I put the mysql-connector-j-8.0.33.jar (/home/glassfish/glassfish4/glassfish/lib/mysql-connector-j-8.0.33.jar) in the users path before I execute the app which will refer to the driver to connect to the mysql database. Must I do something like this which does not work :
Comes from MySQL, so the driver is properly loaded and connection established, but Access is denied (or rather, not Granted with user root from localhost). You can check the connection properties and / or the JDBC's URL that you are using.User root, sounds like that you are running MySQL as the root Linux user, can you confirm or are you trying to connect to MySQL with the root user? (Both are bad practice, you should not use root user for running your apps/process - if not explicitly required and we'll know - and/or not using MySQL root user to access to your DB).
mysql:mysql-connector-java is a provides connectivity for client applications developed in the Java programming language with MySQL Connector/J, a driver that implements the Java Database Connectivity (JDBC) API.
Affected versions of this package are vulnerable to Improper Authorization via the MysqlSQLXML::getSource() function. A malicious actor with high privileges can access all of the MySQL connector's accessible data and crash the connectors.
I am using the CaptureChangesMysql processor to read the events data from mysql but it failing with the connection error as "org.apache.nifi.reporting.initializationexception can't load database driver"

The Driver path is "/Users/kiran/Downloads/mysql/mysql-connector-java-8.0.17.jar" i have tried this as well but getting the error as this path is not a valid File or Url . attached the screenshot for your reference .
2. The JAR may be a corrupted jar so NiFi process might not be able to read the driver class from this jar. So please list the classes present inside this JAR using the following command.. or try to grep the class.
Example: Try to check the existence of this class in the JAR, By the same user who is running the NiFi process.
i am getting the error "Failed to register JDBC driver. Ensure MySQL Driver Location(s) and MySQL Driver Class Name are configured correctly. org.apache.nifi.reporting.InitializationException: Can't load Database Driver"
Not sure how to fix your issue, but I have succeeded in using MySQL. My documents for this is really long so Im going to giving you the MySQL configurations I have. You may have to adjust these steps for your needs.
In any case, if you are using mysql-connector-java 8.0.xx,
currently you can not use versions above 8.0.22.
There is an open keycloak ticket which can not be fixes by library Update.
The connector itself is a single file named mysql-connector-java-X.X.XX-bin.jar.Extract this file from the downloaded archive to a location on your hard drive that is accessible from RapidMiner Studio.
If the driver classes for both the bundled and the newly created connectors is com.mysql.jdbc.Driver the MySQL Connector/J is being used.If it is org.mariadb.jdbc.Driver, the bundled MariaDB Connector/J is used.
The search service can find package by either name (apache),provides(webserver), absolute file names (/usr/bin/apache),binaries (gprof) or shared libraries (libXm.so.2) instandard path. It does not support multiple arguments yet... The System and Arch are optional added filters, for exampleSystem could be "redhat", "redhat-7.2", "mandrake" or "gnome", Arch could be "i386" or "src", etc. depending on your system. System Arch RPM resource mysql-connector-javaMySQL Connector/J is a native Java driver that converts JDBC (JavaDatabase Connectivity) calls into the network protocol used by theMySQL database. It lets developers working with the Java programminglanguage easily build programs and applets that interact with MySQL andconnect all corporate data, even in a heterogeneous environment. MySQLConnector/J is a Type IV JDBC driver and has a complete JDBC featureset that supports the capabilities of MySQL.
