1.
ec = (EOEditingContext)(session().defaultEditingContext());
contactList =
(NSArray)EOUtilities.objectsForEntityNamed(ec,"Contact");
2.
EOFetchSpecification fs = new
EOFetchSpecification("Contact",qual,nameOrderingArray);
fs.setRefreshesRefetchedObjects(true);
contactList =
session().defaultEditingContext().objectsWithFetchSpecification(fs);
If qual and nameOrderingArray are null in option 2, I think they are

I am a relative neophyte using webobjects. I am also just starting with
wonder lots of fun.
I have a database driven app that I sometimes update through my cocoa
app. I would like to do my fetch and be sure I get fresh queries from
the database? I am doing my queries like this:
contactList = Contact.fetchNotDeleted(contactEO);
it returns an array. my problem is that if I were to update the table
from my cocoa app this array is not coming from the database but from
cache. I want to set up to do a query from the database all the time.
is there a simple solution?

Re: How does concurrency control work in WO?
Hello, This is a very timely thread for me, and very interesting blog entry. In my app, I get hit several times a day with the perfect storm of having to deal with extremely high peak traffic from users(mostly, but not all, read only) at the exact time that I have to run a background thread that needs to rip through the database, reading and updating a huge amount of data. The changes made by the background task need to be made available to the users ASAP (that's why they are there, they want their data and they want it now!). After suffering through two of these peaks where the app response and the background thread both got slower and slower until they finally ground to a halt and required a reboot of the server, I decided to put the app in maintenance mode (relegating users to the main page) for the 20 or so minutes it takes the background thread to complete, and then let everyone in. Doing it this way, the background thread really rips through its calculations, and then the server has no problem serving the high peak traffic with the background thread out of the way. However I really don't like having to lock people out several times a day at peak traffic. I was wondering if there were some type of architecture that could be used where this kind of case could be handled more smoothly, or perhaps this is a sign of something I'm doing wrong at a lower level. Note that it seems like the real problems occur when I have two threads with two different OSC stacks (the background thread has its own) hitting the same database at the same time. Could it be something as simple as putting a delay in my background task? Note that it is doing a lot of in memory calculations, so it's not like it's constantly hitting the DB, although it does hit it pretty hard I think. Would fetching raw rows in the background task really make that much of a difference? It's still hitting (and locking) the database, right? Anyway, just wondering if there are others dealing with this type of situation and how they handle it? Thanks, Jeff On Mar 29, 2009, at 3:26 PM, Guido Neitzer wrote: On 29.

There are several ways of dealing with concurrency: 1. Switch on concurrent request handling with the property: -DWOAllowsConcurrentRequestHandling=true Note that this was set through JavaMonitor with the -D property notation. Using concurrent request handling has several implications (see EOF part). 2. Use more instances. This might be the least painful way in regard of locking issues, but the most painful in regard of data freshness. 3. Define your bottlenecks better. 4. Use multiple EOF connections to the database (Wonder has ways of doing this automatically). As soon as you have concurrent request handling you need to deal with the following: - Data freshness - Caching - Locking - Valid data (Which write wins? Dealing with freshness again.) You get most of this for free if you use ProjectWonder, which I highly recommend. You need to use correct locking of your editing contexts (see ERXEC from Wonder or MultiECLockManager, search on Google for more information). If you just enable concurrent request handling, EOF will still stay single threaded for one instance as long as you don't use for example a new object store coordinator for long running transactions. Be aware that all this will bring you into dead locking and data freshness hell as long as you don't really know, what you're doing OR as long as you don't use the "make me and the gods of EOF happy features" from Wonder. cug ___ Do not post admin requests to the list.

I still wonder if GenericUser should have a relationship to both InetOrgPerson and DatabaseEmployee. With that approach, it sounds like GenericUser would have to have it's own data table separate from the other two? Doesn't it need to anyway for the relationship to DatabaseEmployee? Not really. Time for ascii sheep. This is what I have. LDAPModel ---to build path--> UserModel <--to build path DBModel = InetOrgPerson GenericUser <-> Employee (InetOrgPerson/parent) The only relationship (on the right) uses "employee_id." This approach makes the ldap side of things the starting point since that is the store that knows what type of user the person is. If ldap authentication is successful, I query for the matching GenericUser which is essentially an ldap person since GenericUser inherits from InetOrgPerson. Then, I can test for the related employee record. If there, foo, if not, bar - depends on the app. It sounds like your preferred approach would be to create another table for GenericUser making it a database entity instead of inheriting from InetOrgPerson. That could work too. The problem there is then I have two entities, InetOrgPerson and GenericUser that have to have similar attributes, including "usertype," "email," etc. And, when a new Employee is created, I'd have to force the creation of a GenericUser. I can see advantages each way and it's too bad I'm somewhat at the mercy of the greater campus. T I'm trying to abstract everything so that I can pick and choose what gets used on a per app basis. - if I change the table for "GenericUser to "GenericUser" it works as expected. However, there is no such "table" or object in my LDAP directory. And I'm concerned that with that setup attempts to write to the directory would fail. It should be OK like that.

Database Outage Detection
Hello; I have a project where the database goes down every so often. Obviously the right thing to do would be to stop that happening at all, but this is not under my control so I would like my WOA to be able to react to this in some constructive manner. The JDBContext throws an EOGeneralAdaptorException (runtime) when a database connectivity problem occurs, but there is no information about what model was involved or what sort of error occurred. I can get access to the SQLException involved, but I don't think this is going to help me. Anybody doing anything interesting in their systems to detect this? cheers. ___ Andrew Lindesay www.lindesay.co.nz ___ Do not post admin requests to the list. They will be ignored.

Re: WOWODC West

With only one session all Flor was able to do was discus some of the basics of JC and show off the JBND framework. D2JC wasn't even touched upon. There simply wasn't enough time to cover what would be needed to really have people understand JC and D2JC as well as things like AJAX and WOnder. I mean really, I think D2JC and JC with JBND are both probably far easier to learn than learning how to make HTML sort-of act like a rich client. Hmmm, maybe you should do a session on this? It would be truly interesting to see a Client-side bake off where JC and Web clients are put head-to-head by giving a set of basic requirements and see not only which technology can implement it more fully, with better usability, in an hour. We get Anjo on the D2W side. Anyway, Getting started with JC and intro to D2JC are really pretty basic and I now that WOWODC is being divided, I really think they would belong in WOWODC East. With that said, I would be willing to sit down with anyone interested at WOWODC West to go over the basics, as far as I understand them. Given how very few people have seen it or know how it works, it seems appropriate to West more than East.

WebServerResources served through Tomcat
Hi all, I thought I had seen a similar discussion of this lately but I can't find it now. I'm deploying to Tomcat and since I have only a couple users and very few images/css/etc to serve, I'm just serving them right through Tomcat instead of having a separate Web Server setup to serve them. Pre-NewHotness I had made an addition to my build.xml file to drop the WebServerResources in my application's root which allowed me to have Tomcat serve the static HTML resources directly instead of having WO serve them. I guess this is pretty much the same as doing a split install where the WSRs are in a directory in the Apache root. I would call them using a URL like: Is this the only way to accomplish what I want? Is there a better way that won't require modifications to the build.xml file? I'd like to keep it as a stock build.xml file. Thanks! Dave ___ Do not post admin requests to the list.

Re: Undo manager and AJAX
Greetings Fredik, It is not entirely impossible. There are few papers on this subject under the heading Delta-Grid by Susan Urban. The general idea is that the "undo" manager has take in consideration all applications (processes) that write to it. On writing, a change record derived from the database's log stream is used to establish a set transaction list that constitutes the undo stack. The trouble for most WO apps is that such an undo inherently means changing state for other connected clients that have data check out from clean to dirty, which they will only discover on submission. I hope that helps a little bit. Later, Dan Beatty Ph.D. Student Texas Tech University On Mar 30, 2009, at 10:03 AM, Fredrik Lindgren wrote: OK! Seems like I should keep away then!

However, when you stop using session.default, and start using lots of peers that are very transient, I believe that ends up not really working out practically. Doesn't each EC have its own undo manager on it, so you would only be able to undo the transactions from a single EC and it wouldn't be aware of its peers' transactions? From what I understood, this was mainly for undoing changes from an ECs POV, so deletes would get re-inserted etc. As far as this makes sense... e.g. your didInsert() code would get called again wreaking whatever havoc you'd expect after such a move.

things about that one:

But JPedal dies have a GPL-ed version, which works wery well:

On Mar 30, 2009, at 13:18, David Avendasora wrote: This is the approach I was thinking of. Have the client keep track of how long since the last server communication (I have no idea how to do that...) and set a timer based on the session timeout value. It's only job would be to give the user a few minutes warning to finish what they were working on, extend the session (if possible, a ping as you describe below would be perfect) or quit. Hm, might be easier then I thought, using: http://developer.apple.com/documentation/MacOSXServer/Reference/WO54_Reference/com/webobjects/eodistribution/EODistributionContext.Delegate.html Most definitively something worth looking into at some point. Also, this strategy is not exclusive of the constant-ping strategy, so I might provide both in WOJCKit at some point. Will put it on my to-do list. Another approach I considered at some point is to have the client "ping" the session at small intervals. Now, this should be fairly easy to do, and should ensure that the session never expires. There are some potential problems with this: - multithreading: the "ping" of course will get scheduled on another thread, which EOF might not like. One could schedule it to happen on the EDT, but that might result in an occasional glitch in the GUI. Or, maybe if using a stateless RMI method for the purpose of the ping, this would not be a problem - session accumulation on the server: not sure what the implications of this could be. The biggest draw-back I see here is the longer the session hangs around, the more stale the data is getting. In short, you are making things easier for the user, at the expense of a lot of time and care making sure that your client-side application has fresh data. It could be worth it, but maybe not. Yeah, data freshness is a major pain in the ass. Honestly, unless it is really, and I mean *really* important to the client to constantly have super-fresh data, I am happy to live with it getting a few hours stale.

In D2JC I get a nice, "Your Session has Timedout on the server. The application will quit now." dialog box the next time the client tries connecting to the server. Yeah, you also get that in non-direct development. Though I believe there are ways one can do something JC does not expect, and end up with an exception instead of this message. Have not experimented much with it though. Hmm. I haven't ever gotten anything with D2JC except that dialog. I also get it if the server has become unreachable. Note, that depending on how much data is cached on the client, you could be working for quite a while on the client without ever talking to the server because if it doesn't have an explicit reason to talk to the server, it doesn't. The default is plenty of time if someone is actively using the client application, but being a desktop application most users will expect to be able to leave it running for hours at a time without actually using it. You need to balance this expectation with data-freshness and such and come up with an appropriate timeout for you particular situation. Also, users simply need to know that the data they are accessing is not stored locally. Session timeouts are one of the aspects of this. But, I agree, ideally we want to make it as convenient for the user as possible. With that said, I think it would be much better to have a more pro- active approach to session timeouts. Some type of notification to the user that their session is going to timeout if they have unsaved changes, and an option to automatically reconnect without a relaunch would be very helpful too. I have not implemented these things, but I don't really see a reason why they couldn't be. Flor probably has some ideas on how to do this as he more directly manages the client-server connection since he doesn't use WebStart. The problem is that the server can't just "inform" the client of anything, as client-server communication is request-response based. It *might* be possible for the client to time the period elapsed since the last request, and notify the user based on that. However, this might be tricky. Or it might not... I am not sure, never tried that. This is the approach I was thinking of. Have the client keep track of how long since the last server communication (I have no idea how to do that...) and set a timer based on the session timeout value. It's only job would be to give the user a few minutes warning to finish what they were working on, extend the session (if possible, a ping as you describe below would be perfect) or quit. Right now this isn't a huge issue as most users are used to the concept of a Web session timing out without warning so they seem to be able to grasp that a desktop application can do the same. Some websites warn you they are about to timeout, but not all. Another approach I considered at some point is to have the client "ping" the session at small intervals. Now, this should be fairly easy to do, and should ensure that the session never expires. There are some potential problems with this: - multithreading: the "ping" of course will get scheduled on another thread, which EOF might not like. One could schedule it to happen on the EDT, but that might result in an occasional glitch in the GUI. Or, maybe if using a stateless RMI method for the purpose of the ping, this would not be a problem - session accumulation on the server: not sure what the implications of this could be. The biggest draw-back I see here is the longer the session hangs around, the more stale the data is getting. In short, you are making things easier for the user, at the expense of a lot of time and care making sure that your client-side application has fresh data. It could be worth it, but maybe not. In short, I think it all depends on your needs. I agree 100%. There should be some properties-based setting that will still set the maximum session life. I'd be happy to implement the "ping" system, and put it into WOJCKit, if somebody else has the time to test it. I am wy too busy at the moment to deal with that. Anyone interested? I'd be happy to test it if there's some way to use it with D2JC, otherwise, I'll test when I start my JBND project. Should be soon! Dave ___ Do not post admin requests to the list.

The author started porting it to ruby recently: http://github.com/ plessl/wkpdf/tree/master I started to make a wrapper for wkpdf to make PDFs from WO-generated pages a while ago, but got side-tracked...

At the time it all seemed so perfectly reasonable, it was just another option to check in Xcode. And you know, what? It has worked great for almost 5 years!

I did give up Vertical Inheritance along the way and I've never even considered Maven, so I'm not completely crazy!

With only one session all Flor was able to do was discus some of the basics of JC and show off the JBND framework. D2JC wasn't even touched upon. There simply wasn't enough time to cover what would be needed to really have people understand JC and D2JC as well as things like AJAX and WOnder. I mean really, I think D2JC and JC with JBND are both probably far easier to learn than learning how to make HTML sort-of act like a rich client. It would be truly interesting to see a Client-side bake off where JC and Web clients are put head-to-head by giving a set of basic requirements and see not only which technology can implement it more fully, with better usability, in an hour. Anyway, Getting started with JC and intro to D2JC are really pretty basic and I now that WOWODC is being divided, I really think they would belong in WOWODC East.

Re: JavaClient session timeout?

The next request from a client coming to the session gets refused, the client app is informed of why, and the client application displays a Swing modal window to the user telling the user that the session timed out, and when the user hits OK, the app quits. Is there built-in notification or do you have to handle it manually? Well, there is the above mentioned handling. I am not sure if there is a way to override it with some manual handling. I'd be interested in this though, so I might take a look. However, I have other priorities at the moment. Please let me know if you get into it and find something! I will do the same...

Hey! I resemble that! That was just a poke at David A, a wild eyed lunatic that works in a cookie factory and uses JC. ;-) Not only JC, but D2JC and he deploy on Windows in Tomcat! It's a good thing that he works for a cookie factory :-P When I was young, my mother always said that sugar would rot my brain (the beer came later). David is living proof of the truth of this! Tomcat on Windows, eh? Wow, I had no idea it had gotten so bad. It is a wonder he does not add Maven in there. So this is what happens when I take a Friday afternoon off?! For your information, I learned WebObjects and Java together while deploying my D2JC app on Windows in Tomcat. At the time it all seemed so perfectly reasonable, it was just another option to check in Xcode. And you know, what? It has worked great for almost 5 years! Transitioning to WOLips though was more difficult with this setup. It forced me to understand the structure of a WO application when I was happily oblivious before. I did give up Vertical Inheritance along the way and I've never even considered Maven, so I'm not completely crazy! (cough, Lachlan, cough) :-) I know that Java Client didn't get a great response at WOWODC last year, which is disappointing, but we hardly scratched the surface. With only one session all Flor was able to do was discus some of the basics of JC and show off the JBND framework. D2JC wasn't even touched upon. There simply wasn't enough time to cover what would be needed to really have people understand JC and D2JC as well as things like AJAX and WOnder. I mean really, I think D2JC and JC with JBND are both probably far easier to learn than learning how to make HTML sort-of act like a rich client. It would be truly interesting to see a Client-side bake off where JC and Web clients are put head-to-head by giving a set of basic requirements and see not only which technology can implement it more fully, with better usability, in an hour. Anyway, Getting started with JC and intro to D2JC are really pretty basic and I now that WOWODC is being divided, I really think they would belong in WOWODC East. With that said, I would be willing to sit down with anyone interested at WOWODC West to go over the basics, as far as I understand them. Dave ___ Do not post admin requests to the list.
