Hello Tarun,
Try looking at the SQL being generated. To do this, you can right-or-
control-click on your executable under the "Executables" group in
Xcode, select "Get Info", and in the arguments tab add:
-DEOAdaptorDebugEnabled=true
Then when you run it, you'll see the SQL in the log.
Hope this helps!
Regards,
Mark

This is what is in my VaultUser.plist file (inside of WOVault.eo)
attributes = (
{
columnName = LOGIN;
externalType = CHAR;
name = login;
valueClassName = NSString;
width = 40;
},
{
columnName = PASSWORD;
externalType = CHAR;
name = password;
valueClassName = NSString;
width = 40;
},
{
columnName = "USER_OID";
externalType = NUMBER;
name = userOid;
valueClassName = NSNumber;
valueType = d;
}
);
I believe that the login attribute is 'login'. I tried changing it
to something else and I get an error when running the application,
so I think I have it correct.

Is the login attribute 'login', or something else? You need the
attribute name from the model here, not the database column name.
That's all I can think of at this point!

So I've been hanging out in the J2EE world for a while, all the
time looking at WebObjects. Finally came up with a little self
project that I thought would be nice to implement in WebObjects,
so I'm jumping in.
However I'm currently having an issue with retrieving objects
from the database. Here is a sample sniplet that shows what I'm
trying to do:
// allow user to log in
Session session = (Session)session();
EOEditingContext ec = session.defaultEditingContext();
System.out.println(login);
NSArray users = EOUtilities.objectsMatchingKeyAndValue
(ec, "VaultUser", "login", login);
// NSArray users = EOUtilities.objectsForEntityNamed(ec,
"VaultUser");
Now, the second commented line works, but the first doesn't even
though I have a row in the database where the login column is
equal to the value that "login" is.
Any ideas? I'm stumped. (BTW, I actually took this code from one
of Apple's demo applications, iShack, I think)
Thanks,
Tarun
