That NPE is a result of your Main Bundle being null ... If you're not running inside of a bundle, it falls back to using JavaFoundation as your bundle (this officially explains why when things get funky people end up launching JavaFoundation.woa!). Double check that JavaFoundation is, in fact, in your classpath.
At the top of your main method, add:
System.out.println("Main.main: main bundle = " + NSBundle.mainBundle()); System.out.println("Main.main: JavaFoundation bundle = " + NSBundle.bundleForName("JavaFoundation"));
In my main method, this prints out: Main.main: main bundle = <com.webobjects.foundation.NSBundle name:'JavaFoundation' bundlePath:'/System/Library/Frameworks/JavaFoundation.framework' packages:'("com.webobjects.foundation", "com.webobjects.foundation.xml")' 212 classes > Main.main: JavaFoundation bundle = <com.webobjects.foundation.NSBundle name:'JavaFoundation' bundlePath:'/System/Library/Frameworks/JavaFoundation.framework' packages:'("com.webobjects.foundation", "com.webobjects.foundation.xml")' 212 classes >

PS, for eclipse people -- that "Main.main" is a result of a template I have that's really handy. I call it "sop", and it's defined as System.out.println("${enclosing_type}.${enclosing_method}: ${cursor}"); So I can type sop<cmd-space> and it will fill in the class and method name of where the cursor is located. Just spreading the love :)

It's a lot easier than that .. Here's a little bit of sample code from a test main method I have:
public static void main(String[] args) throws MalformedURLException { EOModelGroup.defaultGroup().addModelWithPathURL(new File("MyEOModel.eomodeld").toURL()); EOEditingContext ec = new EOEditingContext(); TestEntity te = ...; ec.saveChanges(); }
classpath contains: my source frontbaseplugin.jar javaeoaccess.jar javaeocontrol.jar javafoundation.jar javajdbcadaptor.jar javawebobjects.jar javaxml.jar

The most promising has been the approach described here: http://www.wodeveloper.com/omniLists/eof/2002/March/msg00018.html My code looks like this (Import.java): public static void main (String args[]) {
try {
JDBCAdaptor adaptor = new JDBCAdaptor("JavaJDBCAdaptor");
EODatabase database = new EODatabase(adaptor);
EODatabaseContext dbContext = new EODatabaseContext(database);
EOObjectStoreCoordinator.defaultCoordinator().addCooperatingObjectStore(dbContext); //Using EOModelGroup.defaultGroup() caused an exception (same one reported below), so I created a new one instead.
EOModelGroup modelGroup = new EOModelGroup();
EOModel model = modelGroup.addModelWithPathURL( new File("MyModel.eomodeld").toURL() );
adaptor.setConnectionDictionary(model.connectionDictionary());
database.addModel(model);
// this causes an exception
modelGroup.loadAllModelObjects();
} catch (java.net.MalformedURLException e) {
e.printStackTrace();
} ..... } When I run it I get this exception: Exception in thread "main" java.lang.ExceptionInInitializerError

... 13 more I've included all the necessary jars I think: EOAccess, EOControl, JavaFoundation, JavaXML, JDBCAdaptor, FrontBasePlugIn Any ideas are welcome. Thanks! John ----- Original Message -----Sent: Monday, January 30, 2006 3:24 AM Subject: RE: EnterpriseObjects in a regular Java application
