Trying to connect to MySQL database using Oracle's SQL-Developer receiving the 
following error message:

   Status: Failure -com.mysql.jdbc.Driver
or
   Status: Failure -Unable to find driver: com.mysql.jdbc.Driver

Download mysql JDBC connector from:
   http://dev.mysql.com/downloads/connector/j/5.1.html

extract it on your PC and take the following file:
   mysql-connector-java-5.1.5-bin.jar

... place it into sqldeveloper\sqldeveloper\extensions

then go to sqldeveloper -> Tools -> Preferences
   Database -> Third Party JDBC Drivers
click "Add Entry" and select mysql-connector-java-5.1.5-bin.jar

restart sqldeveloper and you should be able to connect to mysql at this point.
