Accessing MySQL Remotely

By default, you can access MySQL only from the localhost. In order to access it from the network, you have to modify your my.cfg or my.ini:

Remove or comment out skip-networking option (by default in latest versions of MySQL this version is not present in configuration file)
add (or modify) bind-address with ip of your machine on which MySQL is running

java.lang.NoClassDefFoundError: Files

If you encounter the following kind of Exception, you probably configured %JAVA_HOME% variable incorrectly:

java.lang.NoClassDefFoundError: Files
Caused by: java.lang.ClassNotFoundException: Files
        at java.net.URLClassLoader$1.run(URLClassLoader.java:200)
        at java.security.AccessController.doPrivileged(Native Method)

        at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:316)
Could not find the main class: Files.  Program will exit.
Exception in thread "main"

For example, this could happen during GlassFish startup. The solution is to fix %JAVA_HOME% environment variable, so it would point to correct Java installation location.
