April 2008 01:23:45 MESZ An: sj...@apple.com Betreff: the notorious WebObjects case Hi Steve, I am a software developer in the custom solutions business. Our company develops mostly web based software. Traditionally we use WebObjects for this, because Webobjects is a great piece of software, because we like WebObjects. Over the time I've used a lot of different Web frameworks: plain JavaServer Pages ( http://java.sun.com/products/jsp/ - only good for very basic stuff), Apache Struts ( http://struts.apache.org/ - one word: primitive), Apache Tapestry ( http://tapestry.apache.org/ - somewhat of a clone of WebObjects but subpar and crippled), a little JavaServer Faces in a single project ( http://java.sun.com/ javaee/javaserverfaces/ - very intricate) and in a current project Apache Wicket ( http://wicket.apache.org/ - this one actually somewhat compares to WebObjects but misses EOF). WebObjects is still the best but sadly customer confidence dwindle. While I like WebObjects most for its efficiency, beauty and maturity, most of our customers either never heard of it - or - if they know it - slowly loose faith in it. In the old days customers explicitly asked for Webobjects but now it gets harder and harder each day to convince customers to choose WebObjects as base technology for new projects we implement for them. Mostly the main concern is uncertainty about the future of WebObjects, sometimes vendor lock in and more and more because it is proprietary technology. We used most of the technologies mentioned above because our customers insisted on it - not because we wanted to do so. The competition for the mind share all those open source frameworks create also plays a role in this. Now I think WebObjects has still a lot of potential, despite its currently decreasing mind share and support (less and less WebObjects sessions at the WWDCs, slow update cycle with almost no new features in the last years (I like to see full fledged AJAX support, HTML 5, annotation based authorization and security, integrated Unit testing support - to name a few.)). Why not repeat the success of WebKit? WebKit turned out to be a huge success lately, it gets picket up by a lot of projects and companies, it was the first to pass the Acid3 web standards test. Why is that? I think a great part of this success comes from being open source. People grab the code, fix bugs, extend it, tweak and port it to their needs and integrate it easily in their products. Even Apple profits from this development. To me WebObjects is like the older brother of WebKit - it just lives on the other side of the web - the server. Both get together less and less often but when they meet they're still the number one team. Apple could open source WebObjects and people will come and improve it. That would make a great WWDC announcement. keeping the faith, Lars cheers, Lars ___ Do not post admin requests to the list. They will be ignored.

Re: Instance gets down after approx 500 hits; Database backup; Connection pooling with Single Database Context
Hi Daniel, On Apr 23, 2010, at 10:59 AM, Daniel Roy wrote: Hi, I work with Farrukh :) The application was indeed not responding as I recall. Which is odd, as it did not seem to be doing anything at all. Perhaps the app gets slow, the woadaptor gives up on it and marks it as dead and sends no more requests. The app then recovers and is idle, though effectively dead. Also, we do dispatch requests concurrently (WOAllowsConcurrentRequestHandling=true). I wonder if enabling ERXStatisticsStore would give us some useful information It might. It should indicate if requests start taking longer to process. You could also enable WO logging (see WO's apache.conf) to see what the woadaptor has to say.

Instances stop responding and we need to use JavaMonitor to stop/start the instance or sometimes when JavaMonitor can't perform the operation need to kill the java process.

Which database? Using Wonder? I'm sure there are indexes. Can you explain sub-optimal SQL in this context? We use PostgreSQL and completely dependent on Wonder extensions.

Re: Statistics
I still don't have enough info. :-( All I know is that the elapsed times between the session awake and sleep are very long, which we started noticing immediately after a release (I think). So I don't know yet if it's SQL, network, or something else in the app. There was an upgrade to Oracle 11g on the database side. if you can replicate this in production yourself, you can also setup a dev-only instance of your app with ERProfiling enabled. ms ___ Do not post admin requests to the list.

Linux Apache 2.2 webserver update causing problems
Hi, Wondering if someone has been having issues when updating their linux box with the latest security patches. We had an update on Thursday, April 22 and after that we started to experience problems with one of our WebObjects applications. Specifically...the sessions are being redirected from one instance on the other causing timeouts. When the refresh button is hit, the application returns on the original instance and the app continues normally after this. The instance number does not change on the URL. The code on the application has not changed. In addition, when running on a test webserver which is a OSX Apache 2.2 we are not having these Webobjects issues. Here's the full list of patches that were downloaded. Have you seen problems with webobjects apps after doing these updates? Thanks in advance.

Re: Linux Apache 2.2 webserver update causing problems
Hi! Have you tried to run the apachectl restart (or graceful) command while the apps are running? In rare occasions, I find that if I launch a new instance of a WO App (that has other instances already running), some Apache worker threads won't be able to talk to the new instance. If I set the old instances to refuse sessions, I start getting errors on some requests (not all) until I restart apache. I was never able to reproduce this on dev or staging machines, so I don't know where the problem is. I just got used to run an apachectl graceful command after starting new instances. This is on FreeBSD, but it should not matter, if your problem is the same.

I'm using an AjaxSubmitButton to submit a form and pop up an AjaxModalDialog
in the process. Does anyone know of a way that I could do that same
submission when a user presses Enter in any of my form fields?
I've tried using the js click() method to no avail.
Thanks,
Ben
Code:
wo:form id = quickorderform
Part Number
wo:textfield id = purchasePart size = 20 value =
$purchasePartNumber default = catalog part # onkeydown=if
(event.keyCode == 13)
document.getElementById('quickOrderSubmitButton').click()/
br /
Qty
wo:textfield id = purchaseQty size = 20 value = $purchaseQty
numberformat = 0 default = qty onkeydown=if (event.keyCode == 13)
document.getElementById('quickOrderSubmitButton').click()/
br /
wo:AjaxSubmitButton id = quickOrderSubmitButton action = $purchase
value = purchase/wo:AjaxSubmitButton
/wo:form

No worries, it takes a while to find all the bits. Reading over the
JavaDocs might be a good idea, you never know what you will find! And

Re: Statistics
This tells you what thread took the long time and it gives you a snapshot of what every thread was doing *HALF-WAY* thru the long time. In other words if your log.ERROR is set for 30 seconds then the log.WARN message shows what all threads were doing at 15 seconds into the request .. thus giving you a fair idea what was going on in the entire app instance. On Apr 23, 2010, at 2:35 PM, Ricardo J. Parada wrote: Quick question on this stuff... :-) When a request is taking long, this just logs the stack traces of the different threads in the application? Is that what this gives you?
