Dave,
I had a legacy swing based Java application that was using a home-
spun data
access layer. The powers that be decided they wanted to quickly
move to a
web application. I did not/still do not have the time to re-write the
entire app because it is huge so my team wrote a flash front end
quickly and
interfaced that with a bunch of the legacy objects and methods that
had been
wrapped up and deployed within Tomcat (I realize it is not the best
method
but money and time were short). We are still using the home spun
ORM. I
want to move to a better ORM and I had worked with WO on a couple of
projects in the past and remember the power of EOF so I suggested to
my lead
developer to look into it. He created a model and reworked some of
our code
to use the EOF Java Objects but it is not working. I am pretty sure
that it
has something to do with loading the model, which brings up your
second
question. Yes, I think it can't find the model.
Yes, you can do what you want. There was an example somewhere called,
I think, JavaTool. /System/Library/WebObjects/JavaApplications/
javaeoutil.woa on your hard drive is another example that this is
possible.
There are two approaches to this: the easy way and the hard "fight the
tool" way.
The easy way is to package your app as a .woa bundle with the models
in App.woa/Contents/Resources and the working directory at launch of
App.woa. This structure is what allows all the automatic loading
behavior you are expecting.
The hard way (and I suspect it is not all that hard) is to create the
default model group and then manually load the model(s). See the
JavaDocs on EOModelGroup and EOModel for how to do this.

Hi Darich,
A couple questions because it is unclear what you are trying to do.
1) By Pure Java do you mean a Java Client application where the
client
machines are using a Swing UI?
2) Do you have an EOModel file that it can't find, or are you trying
to create an EOF app without a model?

Hello,
I would like to use EOF in a pure Java application and not from
within WO.
I have searched and not found any good information on this topic.
It seems
that I should be possible but all of the code that I have written
keeps
tanking and if it cannot find the model. Is there any information
on this
subject available?
Thanks
