JDBC connection with mysql on mac

Hi all

I am trying to connect through JDBC a DB.mwb under mysql (MAMP).

I am a mac user (newbie indeed..) I downloaded MAMP and started the local mysql.

The server properly run under / (checked) and the local folder is /MAMP/htdocs/

With Sequel Pro I created a standard TCP/IP connection named connectionDB and it seems properly running on 127.0.01:8889 (root as username and password).

Now, with both server and connection running, I entered the string jdbc:mysql:// but it doestn't connect on refresh (only using jdbc:mysql:// works).

some questions to understand the logic of a connection:

where the phisical database DB.mwb should be stored? under /htdocs/? or under the WebRatio folder and I should specify the path in the connection somewhere? or else the connectionDB creates it automatically somewhere?

i entered also various combination of string jdbc:mysql:// or jdbc:mysql://localhost:8889/ or jdbc:mysql://, nothing seems working

my first time with local server db connection and first time on mac..

thanks in advance

Hi Fulvio,

if you want to connect to the MySQL database with WebRatio you have to define the correct connection string for your dbms. WebRatio suggests you the sample url, for example referring to MySQL it is jdbc:mysql://<host>:<port>/<database> (e.g. jdbc:mysql://localhost:3306/AcmeDB).

For more details please refer to this guide: https://my.webratio.com/learn/learningobject/connecting-the-database

The phisical database file should remain where is stored now, in fact you have only to establish the connection the dbms hosted by the machine.

Hi Alberto thanks for the answer.

I have seen that link which set up a postgresql connection while i am tring a mysql one (as per webinar)

I tried to run this connection and it asked me to download the driver and put it in the webration folder.

I read on the forum the need of renaming it and i did but in any case it did not work (for postgresql)


I returned on the mysql path and now it works.. I dont know why indeed. maybe it needed the driver also before and now it founds it.


About the phisical DB, it seems there is no need to create it separatelly as one you create the connection and syncronize it generate it (somewhere i have to discover yet :)


i would like to report this, may it help someone else not expert as me.


thanks and regards
