Mule MySQL Connector -

i'm trying connect mule mysql database, using tutorial (very new in mule): http://www.mulesoft.org/connectors/mysql-connector

i've come way down, step 6 (test listitems). if go url specified, i'm getting error:

failed route event via endpoint: defaultoutboundendpoint{endpointuri=jdbc://selectall, connector=eejdbcconnector {   name=database   lifecycle=start   this=5b3808ad   numberofconcurrenttransactedreceivers=4   createmultipletransactedreceivers=false   connected=true   supportedprotocols=[jdbc]   serviceoverrides=<none> } ,  name='endpoint.jdbc.selectall', mep=request_response, properties={querytimeout=-1}, transactionconfig=transaction{factory=null, action=indifferent, timeout=0}, deleteunacceptedmessages=false, initialstate=started, responsetimeout=10000, endpointencoding=utf-8, disabletransporttransformer=false}. message payload of type: string 

i've been searching quite long time now, can't find solution. maybe guys can me out?

there xml:

tried newest mysql connector (mysql-connector-java-5.1.29-bin), , 1 stated in tutorial. both didn't work.

anybody know how fix :)?

thanks! bart

the error message says jdbc://selectall, looks data source url incorrect. if @ mysql connector tutorial example, url should in style of jdbc:mysql://localhost:3306/mulesoft_db.
