Re: JESS: New to JESS
In the first screenshot, I see an editor window named awtdraw.clp, but I don't see a file by this name in the navigator view; my guess, then, is that you've used the Eclipse File | Open... menu to try to open a file not in your workspace. This doesn't work. You can only edit .clp files that are actually part of an Eclipse project. We've covered this before on this mailing list, but I'm surprised to see it's not mentioned in the manual anywhere. We hope to have this working by the final release of Jess 7.

If you install it properly, files named *.clp will be opened in the JessDE Editor; otherwise, nothing much should be different. And please, show me an example of JESS code in Eclipse.

I think James Owen wrote: One other thing, something that most old timers even forget. :-) If you re-write equals for a class that already exists or one that you inherit then you have to re-write the hash map table.

RE: JESS: new to jess
Oops! Yes, James and Ernest are correct... an error of omission on my part. You do indeed need to override the hashCode() method, too. I was fortunate enough to win a copy of Thinking in Java 3rd ed by Bruce Eckles at my local Java users group. It is available *free* as an electronic book at http://mindview.net/Books/DownloadSites . If you look at Chapter 11: Hashing and Hash Codes you will find the complete example that James mentioned. Just remember that, by default, equals() only compares object references -- for anything else you have to write a custom implementation.

Re: JESS: new to jess
Thanks. I probably shouldn't be allowed to play with computers right now. Not even email. I pulled my back out again and I'm taking muscle relaxers and mild pain killers (ala Rush L.) and I hope I'm not "hooked" by the time that I get well. :-) Anyway, thanks for the correction and that really IS what I meant in the earlier email. Thanks for keeping me "straight."

Re: JESS: new to jess
Can we get the full reference for this book. Thanks, Dusan Sormaz At 01:40 PM 8/3/2004, you wrote: One other thing, something that most old timers even forget. :-) If you re-write equals for a class that already exists or one that you inherit then you have to re-write the hash map table. There are some examples in Bruce Eckles book. I've forgotten the title and someone borrowed my copy, but ^^ it's available at most book stores and, to my knowledge, is one of the FEW books in Java where you can actually find an example and explanation of rewriting equals and hash map. (Actually, I think, it's the Hashtable, not the Hashmap - although things may have changed with the newer versions of Java Collections. :-) SDG jco Jason Morris wrote: I think that Camillo wrote: How I use eq to compare generic objects?
