RE: [Likely Spam]Re: jdbc connection information
Not using J2EE - just POJO.

BTW, I would recommend to try a JNDI option first. That's where
WebObjects/EOF is different from J2EE - things like DataSources are normally
provided by container (vs. application), with container- specific config
replacing environment property files.

"J2EE" is a broad term (note that I didn't mean EJB)... Are you
deploying your application to Tomcat, Jetty, or something similar?
Those are examples of a "J2EE web container". All of them support
JNDI DataSources (see configuration examples in Cayenne docs per link
below).

Re: [Likely Spam]Re: jdbc connection information

Dan, do you use Ant to build your application? I had a Tapestry
application using Cayenne that had a default DataNode XML file I used
for local testing, but when I ran Ant to build the WAR file, it would
copy an environment-specific DataNode XML file out of
environments/development/....xml (I also had testing, acceptance, and
production directories) to the build directory and package that into
the WAR. So, depending on how I ran Ant, it would pull a different
DataNode XML file (with different connection settings) to build into
the WAR. Worked fairly well for me. (I also had different
.properties files, etc in those target-specific directories.) Would
that approach work for you, too?

Sure. Although your reference to POJO caused wrong associations
("POJO" is also a broad term that can refer to almost anything these
days... Heh, I thought my webapps were POJO? ;-)).
Then DriverDataSourceFactory is the extension point you can use.

No I am not. I'm running a straight POJO application, no container.
