Tarun,
I've worked in many other environments...and to be honest, I
eventually either force them to work like WebObjects, I use
WebObjects, or I just ... don't. :)

Doh!
I thought that might be your reaction. :-)
Thanks to all for your help. I believe that this is the problem
(VARCHAR versus CHAR).
Thanks once again.... (I'm sure I'll need the SQL debugging help
soon, too).
But I'll tell you one thing... so far I like Webobjects. Once you
get over the hump of learning the alternative classes (NSString),
what not to do in EOModel (and to use it as opposed to the Xcode
built-in version), development is really a pleasure (to steal a
tag line from someone else's product)
It sure did put a smile on my face when I started working with it.
Welcome to the World of WebObjects!

This is what is in my VaultUser.plist file (inside of WOVault.eo)

There is your problem. CHAR is fixed width. So if login is
"Tarun", it will only match if followed by 35 spaces. Change the
external type to varchar (variable length char) and regenerate
the database.
Chuck
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
