I am doing some D2JC stuff and I have not been able to get an app to run at all under Java 1.5. I know that WO is really only supported on Java 1.3.1.

I have had no problems with Java 1.4.2, but that is just anecdotal and doesn't mean your app will run.

Hi,

Sorry to re-post this, but I've gone over and over Apple's documentation, and searched and searched the mailing list archives...

I think I'm doing everything right according to the dox, but get an IlleganStateException when attempting to load the .nib archive.

Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: Could not load archive named djcdemo.client.JobFormInterfaceController
at com.webobjects.eoapplication.EOArchive.loadArchiveNamed (EOArchive.java:309)


I'm trying to mix a static .nib file with a direct to java client application. WO 5.3.1, Java 1.5, OS X 10.4.3.

Does anyone have some sample code for this kind of a direct to java client application that they wouldn't mind sharing?

Yours hopefully,

Jarvis

Subject: Direct to Java Client and frameworks

Hello,

I'm trying to get my head around Direct to Java Client...

I've created a Framework to contain my EOModel and classes and associated logic. I would like to create a direct to java client as a separate project, which references the framework.

I'm trying to factor my "business logic" out into a framework that doesn't need to know anything about direct to java or web pages or any of that stuff!

Initially things worked ok - the d2jc application would allow me to create data records, and perform searches, and so on.

The next step was to add an awakeFromInsertion() method on one of the classes in my framework to supply default values for properties. This doesn't appear to be being invoked on the client (no default values), but is invoked on the server when the client saves the data record (which means that it changes the value that user has entered!).

I've tried reading Apple's documentation, but I can't make head nor tail of it - at least where this issue is concerned.

So... How do you set up a d2jc project / application to say "use the model and classes from this framework", and "use the server side method in preference to a local method"?

Hoping someone can help,

jarvis
