(already sent also to users@xxxxxxxxxxxxxxxxxxxxxx) Greetings, as per subject. I have a Fedora 20 x86_64 box here, running LO 4.2.5.2, with all updates installed. NONE of the official howtos, forums, whatever around contains a usable, step by step description of what should be done to connect Base to a local mariadb / mysql database which is running and already accessible from the same computer, both from the command line and from php through the local web server. The closest I've got, AFTER already doing plenty of searches for any variant of mysql, libre office and the several error messages below, is: (configuring the connect to existing database mysql connect using jdbc database name: mydb server: localhost port number 3306 MySql JDBC Driver class: com.mysql.jdbc.Driver (and when I click on "Test Class" I get "the jdbc driver was loaded successfully") user name marco, password required yes Then I click on "Test Connection" I get SQL Status: 08S01 Communications link failure the last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server. I get this on the command line where I had launched lo: Exception in thread "Thread-26" java.lang.NoClassDefFoundError: com/jdbc/mysql/Driver Caused by: java.lang.ClassNotFoundException: com.jdbc.mysql.Driver at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) from http://stackoverflow.com/questions/15827547/java-lang-classnotfoundexceptioncom-mysql-jdbc-driver I read that that message means "problem is not in the code, but you don't have added the driver to your project!!! You have to add the *.jar driver to your project... " but I HAVE added in Options->ADvanced the class path /usr/share/java/mysql-connector-java.jar. Maybe the problem is that this LO (as packaged by Fedora, that is) is using JRE 1.7.0_60 by ORACLE? Also, adding ?autoReconnect=true to the database name, as some of the many howtos and forums I already read, doesn't change anything. What now? First I thought the problem could be on the fedora side (maybe something in selinux/firewall) but why would it work both on the command line and on http/php from the same machine? that's why I am also asking here.
