You set plugin if 1) your plugin doesn't register itself for the
subprotocol or 2) you have more than one plugin that registers for the
subprotocol and you want to pick a specific one. You set driver if 1)
your plugin doesn't set a driver class name explicitly or 2) you want
to use a different driver than the plugin prefers (ie ms's sqlserver
jdbc driver vs the opensource version). For most, you don't have to
care.

Thanks for clearing the doubt. Also just checked FrontBase doc that
only url is required though they are using FrontBasePlugIn. That
hopefully will help to simplify configurations... which I still
don't know how and when to use these two fields.

A proper plugin should not require you to set either plugin or
driver ... The plugin can be guessed from the subprotocol of your
connection url and the plugin can return the default driver name. I
believe this behaves properly in all the common plugins at this point.

Hi Andreas & Mark
My typo error in previous email. I should say that I have neither
set the Driver nor Plugin field, other than url. I don't know if
this is significant to define, but it should work even without,
AFAIK. It is also applicable to FrontBase, too.
I am just curious why it is working. May be you could also confirm
this.
Cheers

For the sake of completeness, here is my EOModel (new) config:
Name: Default
Prototype: EOJDBCMysqlPrototypes
Adaptor: JDBC
url: jdbc:mysql://localhost/test?
capitalizeTypesnames=true&zeroDateTimeBehaviour=convertToNull
username: xxxx
password: yyyyy
driver: com.mysql.jdbc.Driver
plugin: <empty>
That seems rather logical and corresponds to David's tutorial.
My mistake was to follow strictly the video and fill out EOModel's
fields in the same order without checking the field names. But my
EOModel version has this data presented in a slightly different
order than in the video, so the informations (url, driver, plugin)
were misplaced!
So, that was a rather instructive mistake.
And now, let's move on to the next step and keep learning WO.
Mark, by the way: how did you identify the error? via the log?
Cheers,
Andreas

I supposed that you may only need this in url for your eomodel
config:
url:
jdbc:mysql://ip-address/dbName?
capitalizeTypenames=true&useUnicode=true&characterEncoding=UTF-8
username: xxxxx
password: xxxxx
I am using the Driver setting, and not sure its implications. I
thought
this field could just left it empty.
Cheers

That was it! Fantastic!
My EOModel configuration wasn't properly filled out. My fault: I
didn't look
correctly at the tutorial...
Thanks a lot guys.

Does anyone have a suggestion?
Hey Andreas!
I could recreate the exception which you got by using an EOModel with
Driver:
Plugin: com.mysql.jdbc.Driver
These settings work for me:
Driver: com.mysql.jdbc.Driver
Plugin:
Give that a try! ;-)
