Sounds like EOF is confused as to which entity/class it has.
Duplicated primary keys perhaps? Try adding some logging as below.

It's been ages (6years+) since I tried to create a simple D2W app
from that
code, but AFAIR, I had no trouble writing to a file. The only
downside then
was that you don't have working rollback.

I presume the answer is not via the EO (all methods are read-only) as
Chuck suggests, but rather referencing the URL and then using java
file I/O methods to push data directly. Again, at least in its
present
state the model is all read-only and other than that, I'm unsure of
what automagically is supported as an EO.
Well, further mucking hasn't helped. By way of example:
FSFile myFile;
EOEditingContext ec = session().defaultEditingContext();
myFile = (FSFile) EOUtilities.createAndInsertInstance (ec, "FSFile");
NSLog.out.appendln("myFile class " + myFile.getClass().getName());
myFile.takeValueForKey ("/tmp/mytest", "absolutePath");
myFile.setContent("test text");
ec.saveChanges();
on saveChanges, nothing is actually written to disk but the entity
does reflect content="test text". I then have this in the code:
myFile = null;
EOQualifier myQual = new EOKeyValueQualifier ("absolutePath",
EOQualifier.QualifierOperatorEqual, "/tmp/mytest");
EOFetchSpecification myFS = new EOFetchSpecification ("FSFile",
myQual, null);
NSArray myObjects = ec.objectsWithFetchSpecification(myFS);
if (myObjects.count() == 0)
return "No file present called /tmp/mytest";
else
{
myFile = (FSFile) myObjects.objectAtIndex(0);
NSLog.out.appendln("myFile class " + myFile.getClass().getName());
myFile.setContent("test text2");
ec.saveChanges();
return myFile.name() + ": " + myFile.content();
}
At this point, saveChanges() complains that setContent doesn't exist.
