Armin,

Well, it's interesting you mention that, because I tried to use custom 
attributes, but it didn't work. Now I'm becoming aware that you are suggesting 
adding the "jdbc." prefix to the attribute name. My original, and failed, 
attempt looked something like:

<attribute attribute-name="zeroDateTimeBehavior" 
attribute-value="convertToNull"/>

So I guess I will try later your suggestion:

<attribute attribute-name="jdbc.zeroDateTimeBehavior" 
attribute-value="convertToNull"/>

Perhaps I missed it, but I never saw the "jdbc." prefix in the documentation... 
did you?

Thanks!

Luis

since OJB 1.0.4: Another option is to use "custom attributes" to specify 
jdbc-driver parameter (if supported by the jdbc-driver):
http://db.apache.org/ojb/docu/guides/repository.html#Custom+attributes-N10329

the example above would look like (don't know if mysql support this too)

<attribute attribute-name="jdbc.zeroDateTimeBehavior" 
attribute-value="convertToNull"/>

regards,
Armin
