Coldfusion Administration:Adding Data Sources Error

-

* connection verification failed data source: online_store
[]java.sql.sqlexception: communication failure during handshake. there server running on localhost:3306?
the root cause that: java.sql.sqlexception: communication failure during handshake. there server running on localhost:3306?

thats message when try add mysql database using coldfusion admin page. never error when add access database.

where going wrong?

could or suggest something?

1) mysql server running? localhost:3306 standadr port mysql. if have changed port number during mysql installation should change in dsn string in cf well. mysql server either not running or not configured properly.
2) mysql driver using? if trying set dsn standard mysql 3.x driver shipped cf, may have problem. go mysql.org , download latest mysql connector/j + instructions on how install , how configure dsn. bet not have error updated driver if mysql running , configured properly.

ATmega2560-Arduino Pin Mapping

hi community, in last days working on project using arduino mega 2560. on planning pin using found bugs in atmega2560-arduino pin mapping . if right there labels (such pwm) in 'mapped pin name' @ wrong row ( mixed pin numbers right one...) in attachment openoffice calc , pdf file corrected table. ( hope ;-) ) i post here tab separated table : code: [select] arduino mega 2560 pin mapping table atmega 2560 pin out arduino mega function nr name function function function mapped pin name function function datasheet 1 pg5 oc0b digital pin 04 pwm 2 pe0 rxd0 pcint8 digital pin 00 rx0 (usart0 receive pin, programming data input or pin change interrupt 8) 3 pe1 txd0 digital pin 01 tx0 (usart0 transmit pin or programming data output) 4 pe2 xck0 ain0 (usart0 external clock  input/output) 5 pe3 oc3a ain1 digital pin 05 pwm 6 pe4 ...

hello i'm super newb please don't bash me much. i'm using led's , i've connected them correctly (finally) , wondering why program here ( http://www.arduino.cc/en/tutorial/colorcrossfader ) doesn't work? say's haven't declared crossfade. read directions on top , said crossfade needs used list order of colors. isn't declared in main part (void loop() )? or need declared before? nevermind void on bottom , needed before voidloop. lol anyways playing rgb led's wondering if has specific way of making them fade in , out different colors? (brightness , color mixing) code: [select] /* * code cross-fading 3 leds, red, green , blue (rgb) * create fades, need 2 things: *  1. describe colors want displayed *  2. list order want them fade in * * describing color: * color array of 3 percentages, 0-100, *  controlling red, green , blue leds * * red red led @ full, blue , green off *   int red = { 100, 0, 0 } * dim white 3 l...
