Re: Database choices
If you're going to use MySQL with WebObjects in a production environment, make sure to do the following: - create all your tables with InnoDB engine support - the default MyISAM support is non-transactional - make sure to create all your tables with the right charset and collation (UTF-8 all the way). MySQL's internationalization support is excellent but ONLY if configured properly. - make sure to add the correct voodoo to the JDBC connection string for your application so that it uses the right charset / collation over the JDBC connection. While MySQL has worked out quite well for us when used with WebObjects (and PHP), the lack of sequences makes it a less viable choice for projects going forward. These days we go out of our way to design schemas that are WebObjects, Ruby on Rails, Hibernate, and PHP friendly. The MySQL / EO_PK_TABLE paradigm just doesn't fit well in this methodology - PostgreSQL is a much better choice. thanks! -shehryar On Oct 30, 2007, at 11:42 AM, John Huss wrote: For example, the FrontBase mail list archive has this message: Subject: [RESOLVED] Re: Optimization/Caching/Indexing how-to The order of the columns in the composite index definition is very important for your case.

Re: Chat integration
Just recently integrated http://www.instantservice.com/ live chat solution into a WebObjects application. Clicking on a live chat button in the header opens a chat frame at the bottom of the window where contact information (first name, last name) is auto-populated based on the the user logged in to the session. User can type in a question and then click on a "start chat" button to initiate the chat in that same frame. At the end of the chat, the bottom chat frame collapses. This type of integration allows the user to chat and use the application at the same time, making it easy for a live chat agent to walk the customer through a particular flow. Email me offline if you'd like more information on their solution or how we integrated with it. -shehryar On Aug 31, 2006, at 7:30 AM, James Cicenia wrote: How about... cough, cough.. a php solution? http://www.phplivesupport.com/ On Aug 31, 2006, at 9:12 AM, Guido Neitzer wrote: Hi Steve.

Re: XCode 2.4: EOModeler & EOModeler Plugin deprecated?
As someone that has Xcode 2.3 currently installed on my machine, does anyone know if upgrading to Xcode 2.4 will actually delete the applications that have been "deprecated" in Xcode 2.4? On the same note, does "deprecated" imply that a machine with a clean install of Tiger and Xcode 2.4 will no longer have EOModeler / WebObjects Builder etc. on it or does it mean the applications will exist, just aren't guaranteed to work anymore since a critical component that they are dependent upon (the java bridge) has been deprecated. thanks. -shehryar ps. if they are indeed gone, building a (Cocoa) modeler that has the ability to generate not just EOModel files but also Hibernate and RoR model files may be a wonderful third party opportunity (especially with some creative uses of CoreAnimation). That might just be an Übermind product in the making ;-). On Aug 8, 2006, at 10:07 PM, Gaastra Dennis - WO Lists wrote: So how will you be able to edit your EOModels in the future?

Re: generating response in different thread
Christian,
How about having the long response thread generate an http request
(curl?) to a direct action in your app to generate a response which
it then passes up to the main thread for display.
It ain't pretty but it will work.

I have a bunch of pages that can take a long time to generate. I'd
like to show a WOLongResponsePage in the interim. The typical way
of using WOLongResponsePage is to run the business logic or
whatever is taking a long time in a different thread (kicked off by
WOLongResponsePage.performAction()), and once done, generate the
final page with the result of that expensive computation (with
WOLongResponsePage.pageForResult(Object)).
Unfortunately, the pages I have to deal with can't be used with
this pattern. They're slow because they contain thousands of
bindings which each are partly responsible for the slowness.
Getting all the values upfront at once would require me to rewrite
the pages - something I don't have time for.
So what I'd like to do instead is (simplified):
WOLongResponsePage.performAction() {
slowPage.generateResponse();
I think I've figured out how to do WOLongResponsePage.pageForResult
(the slow pages are basically display-only). My problem is calling
generateResponse() from a new thread. Some bindings on the slow
pages are hooked up to the session, and to objects in the session's
defaultEditingContext causing all sort of issues that I'm having
troubles tracking down. So, has anyone ever done this sort of thing
and could give me any advice?
Thanks,
Christian
