Re: Any interest in WOWODC recordings on DVDs?

One of the BSD disto is doing that so that people who can't donate because of organization rules can buy something to give money back to the foundation. Squinting at the screencasts are tough enough with compression artifacts on the text at regular resolution. Plus all the time recompressing and burning... yick. Just put the files on a microSD card.

Re: WOCommunity membership and goals
Speaking for my company, sometimes we are forced to use jQuery for some things. We try to do as much as possible with Ajax.framework (prototype) but some things are simply not feasible without jQuery. We generally have use the two mixed, which is sometimes a source for headaches. A nice thing would be to have a port of the prototype Ajax.framework to jQuery but that's way beyond our area of expertise, I can't even say if it's feasible.

I see jQuery as an important option for Wonder though I am not sure if its the best way to have a separate AjaxPrototype, AjaxJQuery, AjaxMooTools, … framework which would make maintenance a nightmare if you want to keep those feature equal. If I remember correctly long time ago the idea to make some sort of Javascript API wrapper was already discussed / proposed on the list to have only one single Ajax framework and being able choose if you want to use prototype, jQuery or any other supported JS library. I already played with the thought to do some test code in that direction though had not enough time yet. What do you think, is that something the we should realize or does the community want a complete jQuery replacement of the prototype framework? I'm curious about this too, because looking at the surveys, looks like most people use both jQuery and the Ajax framework: Ajax framework from Wonder 81% jQuery 69% Last year: Ajax framework from Wonder 69% jQuery 47% The survey was bit biased because it listed jQuery specifically but not moo tools. This is why we have a Other option, and two organizations listed MooTools in other. I'm with Johann. We should have one server-side framework that supports the main JS libs, or we'll be seeing more frameworks eventually make their way into the Archive attic ;-) Maik ___ Do not post admin requests to the list.

Re: Immortal sessions in production
It's a mess... There are ECs created in some DirectActions, and ECs

in the Session EC. All ECs are ERXECs and no explicit locks happen.
Should I explicitly lock the session EC in the terminate method?

Hi All -
Wondering if someone can throw me some ideas on solving what looks like an
immortal session problem.
- Start up 1 instance in java monitor.
- User lands on sessionless login page. No sessions.
- User logs in. 1 session.
- User logs out. 0 sessions.
- User logs in. 1 session.
- User does nothing. Session times out. 0 sessions.
All looks good. However, we get to the end of the day and the instance has
376 active sessions. But I know for this particular app there are only 6
users, because they are all sitting next door :-) Also, If i now leave this
instance overnight none of those active sessions will go away.
So what could be going on ? Something appears to be creating immortal
sessions, but forced session termination (by the user logging out) and
session expiration seem to be behaving themselves.
If the users don't notice any problems, my money would be on an exception
thrown from your Session.terminate(). Also check the sleep() method to
ensure it can never throw.
I have seen a related problem where two requests come in for the same
session (user double clicks, Ajax etc), and the first calls terminate() on
the session. The second thread is stuck and the app can't gracefully shut
down. IIRC, you would see zero sessions in this case. The fix for this
is to not call terminate() and instead set the session timeout to a small
number of seconds.

JAX-WS Endpoint within a WOApplication
Hi list, I'm trying to implement a webservice using JAX-WS after I concluded that the app that needs to talk with mine can't speak through WOWebServices...

Re: [Wonder-disc] ERXEC and locking

Puzzle: Custom AjaxFlexibleUpload not working in Linux
Hello list,
I have a weird problem that's driving me nuts...
I know that I'm not going to provide enough info to completely debug the
issue so I apologize in advance.
I think I just need a hint to point in the right direction.
I needed a clone of ERAttachmentFlexibleUpload which uses
AjaxFlexibleFileUpload with the only difference in the progress bar (i used
http://twitter.github.com/bootstrap/components.html#progress the striped
bar).
The div structures are different so I chose the approach of cloning WOnder
stuff in my project.
Everything works like a charm on my Mac (even if I deploy the application)
the problem arises when I deploy on Linux...
The upload works but the bar doesn't move and the client browser gets kind
of stuck.
The exact same application (with Project, User and Local frameworks
embedded) has a totally different behavior on Mac or Linux, which makes
sense if I used DBs but there is no DB involved in this issue.
I turned on some logging on the app:
As soon as I start the upload I get a ton of those messages:
DEBUG it.altera.dsl.ajax.ALTFlexibleFileUpload -
AjaxFlexibleFileUpload2.uploadState: {state = 0; }
then after a while I get
DEBUG it.altera.dsl.ajax.ALTFlexibleFileUpload -
AjaxFlexibleFileUpload2.uploadState: {state = 2; progress = 0; filename =
test.mov; }
progress stays at 0 forever... then it completes the upload!
If I use the twin component from AjaxFramework everything works ok both in
Mac and Linux so it's clear that i screwed up something, I just don't know
what.
Any hints/similar issues?
Thanks,
Matteo

Re: Puzzle: Custom AjaxFlexibleUpload not working in Linux
Ok, I think I got a little hint: if the file is big enough (like 10 MB
over a slow ADSL connection) after a while it starts updating the bar...
But it's wy more than 1 second or even the 2 seconds default.
Another weird thing: during the long wait the browser (uhm, Safari) looks
like it's stuck.
BTW has anybody managed to use something like this in WO?

Re: Most requested stuff on Google Moderator
+1 I still think that for a new project it's wise to use WO. Even if it's old stuff ;) because of Wonder and because of what you can do really quickly! I even looked at other frameworks out there just to be fair and nothing comes even close! Maybe tapestry+cayenne? Anyway, for me it's WO for the foreseeable future... So I'd better move my ass and start contributing to Wonder! Matteo On Wed, Mar 28, 2012 at 6:58 PM, ISHIMOTO Ken k...@ksroom.com wrote: +1 I am now and in the future will use WO fro all my Projects.

When I find something better, I am gone. I've been looking since 1999 or so... I look on WebObjects more as a completed library, not an EOL product with no future.

The fact that WebObjects has endured for so long as a relevant and useful piece of technology is amazing. But like all technologies, it can't last forever. The sun is setting (or has set) on WO. It's time to move on; that's what programmers do - our toolset evolves over time - usually it changes dramatically every 5-10 years. This is just another evolution whose time has come. It is sort of sweet and heart-warming to see the outpouring of affection for WO, but the reality is that it's time to move on. The best thing you can do for WO now is to gain experience with other technologies and then help people migrate to them. Cayenne should be at the top of this list. On the HTML side, I'd love have someone find out how hard it is to migrate WO components to Tapestry. The reality is that WO is LEGACY technology. It should be treated as such. That means you continue to maintain your apps that use WO, you find a new technology, and you write your new apps in something else.

The issues will be voted by the community and the most voted issues will become the highest priorities. That is not how Wonder was created and now how I expect that it will continue. If you have a problem, learn how to fix it. Then put it in Wonder. In the past, we had Apple sponsorship and most of the big additions to Wonder between 2007 and 2010 came from Apple… We don't have that sponsorship anymore, and personally I don't think we will survive if we don't pay people for major stuff. I don't think we will survive anyway, but that's another story… Apple funded a VERY small percentage of the contributions to Wonder. Almost all of the contributions I made came from mDimension donating their time, bandwidth, and hardware for the good of the community. Frankly, if Apple hadn't funded the things they did, I would have done them anyway, because I just enjoyed making things. This approach of paying for fixes seems like you're just going to end up with a collection of bounty hunters instead of a community. On top of that, there's no way you're going to be able to afford to pay the market cost for this work. mDimension easily donated a couple hundred thousand dollars of time if you applied their real hourly rate to the work. So on top of encouraging people to only give if they get paid, they're going to be paid crap, so why would anyone even bother? I really don't think things are stagnant because of the lack of money. They're stagnant because the remaining people in the community don't care enough to contribute. I don't buy any of the I don't know how to do X or I don't have time to do X. You have to want it. I didn't know how to write nearly any of what was in WOLips before I started working on WOLips, and likewise with Wonder. I learned WebObjects working on Wonder. I'm would wager that everyone who worked on Wonder was in the same category. Contribution is also positive reinforcement. The coolest times in Wonder for me were always when one person contributing got someone else energized to contribute

High resolution PDF generation
Hi list, in the past I always generated PDF documents on the fly from a WO application by using FOP. Writing a component for FOP is not exactly an amusing task so for a new project I was considering using ERPDFGeneration instead, looks a lot simpler. The problem I'm trying to solve is that I do need the generated PDF to be really high resolution, it's a ticket so it will need to have a barcode and a map to get to the place where the event takes place. I have the map in a vector format so I rasterized it at a big resolution and I'll use the raster file in my HTML template. From some preliminary tests I was kind-of able to accomplish what I need, the PDF gets generated and if i zoom it in it renders with enough detail so I'm happy. But I got there from trial and error so I'm not really sure I'm doing the things in the most efficient way, maybe my images are too big, maybe I could tweak my HTML-CSS so it renders better... Does anybody have to face a similar problem? Is there some docs I could read about this? Any suggestions are of course very welcome, thanks! Matteo ___ Do not post admin requests to the list.

We provide formal education as Application Developer for folks that have already had formal training for a profession but due to various reasons (often medical) must be re-trained to a new profession. The whole thing is 1 year full time school then 1 year full time work. They finish with an official Swiss Federal Diploma. During the first year the students have to take ~33 modules, most of them 40 lessons, some 80 lessons. Each such module covers one topic (DB design, structured programming, OO programming, HTML/CSS, and many many others) and each ends with an exam. I have been doing this for the last 10 years on and off and I also have written several course books. These have been officially published and are available in book stores. Recently I have co-authored a book about OO Development covering the whole lifecycle from Analysis to Deployment. In there I have covered the development part with WebObjects. One of the modules im currently teaching is Implementing an OO multi-user DB app. The general topics of each such module is given by federal regulations but it is up to the school/teacher how these are presented. I am teaching this module using WebObjects. The first part (40 lessons) will follow loosely the old Programming WebObjects 1 (Apple Stuff from 2001, adapted to the new tools etc), whereas the second part (again 40 lessons) will then focus on individual small projects and the methodology and concepts of OOA/OOD. Why do I do this (using that dead thing called WebObjects) in teaching? Pretty simple: it is there, it works perfectly, it is a great thing to work with, it is also a counter weight to J2EE, and I want to promote WO. Bring WO to schools and when the students later on get their jobs they might eventually mention what they have learned - spread the word! Many many moons ago (December 2001) I attended an official Apple Train the Trainer for PWO1 and have been teaching that course several times in the past. Long since no WO teaching but have been working with WO on many projects during the last 10 years. I am currently quite involved with a large customer where I maintain several (rather old) WO-Apps and am currently massively extending an existing D2W app. Big fun and a lot to discover every day. ---markus--- On Dec 19, 2011, at 3:02 AM, Markus Ruggiero wrote: Need this for teaching WO (yeah!).

Re: Ajax UpdateContainer stop
Unfortunately no, I'm stuck with this layout... The problem is that I'm editing a bunch of records, and the records could be edited by another app which communicates via Direct Actions, so I need to continue refreshing a big part of the page to see if the other app changes something in my records. For example if the app changes a particular state of the record I have to disable the TextField, that's why it must be inside.

Ajax UpdateContainer stop
Hi all, I have a nasty problem with an AjaxUpdateContainer set to autoupdate (i set frequency=1 in the bindings): the container contains a lot of stuff including some textfields, the problem is that the textfields must be edited and if the user does not type fast enough, all gets lost or worse it gets partially submitted. Looking in the Prototype documentation i saw that there are Ajax.PeriodicalUpdater#stop and Ajax.PeriodicalUpdater#start The idea was calling stop in the onFocus of the textfield and start on the onBlur but I don't know how to call those methods, I'm really terrible in JavaScript.

Single Table Inheritance
Hi all, kind of a stupid question but in my whole career with WO I never used Single Table Inheritance so I'm kind of a newbie here... I'll try to explain with a small example: I have an entity called PointOfInterest (POI), defined by the main attributes which are name, latitude, longitude, type and with a relationship to a City. I then created two subclasses of POI Restaurant (with qualifier type='R') and some more attributes Club (with qualifier type='C') and some different attributes All is mapped in two tables, one for City and one for POI. Everything looked fine in my head... I find puzzling though that if I ask a City for its POIs I get an array full of duplicates in this example I'm printing out all the POIs for a City: POI name: Open POI Class: your.app.logic.Club POI name: Jazz Club POI Class: your.app.logic.Club POI name: Dal Baffo POI Class: your.app.logic.Restaurant POI name: Zushi POI Class: your.app.logic.Restaurant POI name: Ristorante POI Class: your.app.logic.Restaurant POI name: Dal Baffo POI Class: your.app.logic.Restaurant POI name: Zushi POI Class: your.app.logic.Restaurant POI name: Open POI Class: your.app.logic.Club POI name: Jazz Club POI Class: your.app.logic.Club POI name: Generic poi POI Class: your.app.logic.PointOfInterest POI name: Ristorante POI Class: your.app.logic.Restaurant In reality I only have 6 items in my POI table: 3 Restaurants, 2 Clubs and one row with blank type.

Thanks Chuck, actually POI was not abstract nor there was a qualifier... Dumb me! As this WOApp will have to feed an iOS app I was planning of using ERRest.

Re: multiple instance question, and more
Are MySQL tables InnoDB or MyISAM? You shouldn't have the PK problem with InnoDB... Also for the CPU issue, how many instances are you running What are the deployment variables? In any case, the Apple Push Notification server is unbelievably fast, if you send 50k notifications at the same time you could end up with a lot of your clients calling home at the same time and you could easily clog your application if it can't handle that amount of concurrent connections... you could try to spread the notifications in time and see if it helps. Matteo On 15/lug/2011, at 22:57, Pascal Robert prob...@macti.ca wrote: Le 2011-07-15 à 16:52, Andrew Kinnie a écrit : Greetings, I have 2 issues, the first of which I had before WOWODC, and the second burst into the open yesterday. I have an app, an ERRest app, acting as a push notification server, although thus far now push notifications have gone out to the public, it works for testing. The app is connected to by nearly 50,000 iOS devices which have our iOS app installed. The iOS app connects to Apple to get a token, then calls home (my server) and tries to register itself with my server so that when we do send out notifications, we know which device tokens want which types of notifications. The iOS apps on individual iOS devices connect when running, and send information to my server about the device, the id of the device, other data including the token and whether they want the 4 notification types to be on or off. All this works. (there are approximately 50,000 registered application_device rows currently, though we've not sent any publicly visible notifications). When the app runs, the devices also try and get the last notification of any type that the device has been set to ask for, and display that in a drop down (data pulled from my server) The server uses ERRest to receive this information and to create a device (actually an ApplicationDevice object) based on passed in json, checks the database (MySQL) to see if there is an existing row in my application_device entity/table for the app, and the device id (udid) and if so, updates it with the newly created device's data before discarding the new device and saving the changes in the fetched one. Otherwise, it saves the newly created device. However, 1. Occasionally, two devices try to be created at the same time with the same primary key (which is provided by the EO_PK_Table in the MySQL database). The second device fails with an exception. I gather this is because two separate devices are connecting to the server at approximately the same time, both asking the EO_PK_Table for the next primary key for the entity, then do some things, then try and save. First one succeeds, and the second fails because an object with the PK already exists. I was under the impression that EOF should handle this, but it doesn't seem to. 2. We tried to send out some test notifications yesterday, which exposed some inefficiencies in my model, which seem to have been resolved, but there are still significant issues. Apache and MySQL are fine, neither is pressed, but the CPU approaches 100% usage in spikes on the server (a CentOS VM with 16 GB RAM running Java 1.6 64 bit). Nothing else is running on it. The individual queries in the registration process do not return more than 5 rows, though there are 18 separate SQL calls caused by the registration method, all but one returns 1 row, and the other returns 5. In any event, MySQL has no slow queries. So it's the WO Java processes that seem to be taking up 100% of the CPU. Constantly getting worker-thread broken pipe errors when it is pressed like that. For the record, yesterday we weren't even able to use jstack to see what was going on. But we did see working threads going up to 128.

Re: Concurrent request handling
Hi Chuck,
could you elaborate more on the shared formatters thing?
Don't Do Stupid Things :-) Which boils down to don't share objects that are
not thread-safe, or writable data, at the global level unless you have
appropriate protection. Global being either static members or instance
variables on your application. Shared, non-thread safe formatters are a
common mistake.
we inherited a project that has random (but infrequent) lockups and I found
that in the Application.java
first there is an instance variable
private NSNumberFormatter millionsFormatter;
then a lazy initialization in the accessor method:
public NSNumberFormatter millionsFormatter() {
if (millionsFormatter ==null) {
millionsFormatter = new NSNumberFormatter();
millionsFormatter.setPattern(###,##0.00);
millionsFormatter.setDecimalSeparator(,);
millionsFormatter.setThousandSeparator(.);
}
return millionsFormatter;
}
Could this approach be one of the causes of the lockups? The app runs in
multithreaded mode and there are tons of components with WOStrings bound to
this formatter...
Thanks,
Matteo

Re: Concurrent request handling
Hi Chuck,
there are 30 different formatters (all NS...) in the application and more than
500 WOComponents. if this is not a potential deadlock case, I'll leave them
there... Too lazy!
I'll try to investigate the deadlocks properly, the problem is that they're
very rare and almost impossible to reproduce in our test environment.
Thanks,
Matteo

Hi Matteo,
I don't think that will cause a deadlock. It will cause some incorrectly
formatted input / output. The easiest fix is to move this from Application
to Session and adjust the bindings.
As for the lockups, you really need to get thread dumps to assess those.
jstack is an easy way to do this.

Re: mySQL 5
I totally agree... And I personally don't trust anything that is not CLI ;) Also, when you understand the mechanism, it's pretty easy to setup clusters and replication! Command line is your friend! Matteo On 14-feb-08, at 15:23, Simon McLean wrote: I've often heard that MySQL is complicated to administer, but I've never understood where that opinion came from. Maybe it stems from older versions of MySQL, or maybe people are just referring to replication and clusters which don't have a GUI. Anyway, for the record, MySQL itself (clusters and replication aside) is really easy to administer - just as easy as openbase - double click to install and hey presto, it's running. I've never used clusters in production, so don't know much about them other than that the hardware requirements are pretty extensive (lots of RAM required because they hold the entire DB in memory) and the set-up is command line based. I would also urge you to look at replication as an easier alternative. It's command line based, but dead easy. Kieran has an post on his blog about how to set it up. Why the switch from openbase ? Many reasons. When we made the switch Openbase were charging for all their licenses and the base license for our requirements far out-weighed MySQL's licenses. Performance differential was negligible (again, for our requirements). Another key reason was the size of the community - we rarely use MySQL's commercial support because the community support is so good. Now there is stuff like the Monitoring and Advisory service which is just brilliant. There was also one technical bug-bear we had with openbase. From time to time it didn't shut down properly, or maybe a server fell over, either way when openbase started up it used to go through some table checking process that would take a couple of hours because of the size of our database. It didn't happen often but it killed us when it did. This was a few years back so it's probably fixed or improved by now, but I can still remember the pain! If I were in your shoes I would definitely look at Openbase and MySQL, but also Frontbase and Postgres which both seem to have quite fan base. I don't think you can go far wrong with any of them.

Re: WebObjects training
Try with PL Systems... I believe.Good luckMatteoOn 10-lug-06, at 13:21, Gavin Armstrong wrote: Matteo, Thanks for that. I'm struggling to find anyone who provides the courses in the UK is it possible to do them online? I've emailed Apple a few times but can't get a reply out of them. They seem to be very expensive so patience and books might be the only way forward. Ang suggestions for the books? Patience could be trickier with two young kids :) Cheers, GavinFrom: Matteo Centro [mailto:[EMAIL PROTECTED]] Sent: 10 July 2006 12:14To: Gavin ArmstrongCc: webobjects-dev@lists.apple.comSubject: Re: WebObjects training The courses ARE good... as a first introduction to WO without the feeling of drowning :) IMHO, with lots of patience and a few good books you should be able to learn by yourself! My advice is: If you can, take the courses (at least the first one)... Consider that i'm a trainer, so my opinion might be skewed :) MatteoOn 10-lug-06, at 13:02, Gavin Armstrong wrote: Hi everyone, I'm struggling with WebObjects not least because I'm new to Java and programming in general. What I could really do with is training off someone who know's WebObjects. Due to work and family commitments I'm trying to find some kind of online course that I can study at my pace. I've got pretty much all the books on WebObjects but still feel as though I'm drowning. Anybody got any suggestions? Also has anybody taken the Apple courses (Web 400 Internet Application Development Using WebObjects and Web 410 Advanced WebObjects Development) are they any good or should I just hang on for Chuck's new book.Hope someone can help.
