You can connect to any database that offers a JDBC driver.

Good day erel. Here's my error when i turn my java port into 3306

Terms are important. This is not "java port". If you are talking about ServerPort then it shouldn't be 3306. This is the port that jRDC2 will listen for client connections. It has nothing to do with the database server.
