Re: [JDBC] newbie question: . . .

[Russ McBride]

Nick,

Thanks.  That appears to have done the trick.  At the next step, I'm 
getting a weir error from within the Webobjects EOModeler that says:

NSCFDictionary.setObject:ForKey:attempt to insert nil key

This might be a question better suited for the Webobjects folks though  . . .

I'm not sure if this will solve it, but I'd guess that when your application
asks for the name of the drivers, it is looking for the class, not the jar
file, so your response would be: org.postgresql.Driver

Hi Russ,

Are you using a JDBC driver which you've compiled yourself (using an SDK
and Ant) or one you've gotten from elsewhere?

I've found compiling your own to generally be the best solution.  That
might do the trick.

Regards and best wishes,
