Re: RHEL 6 High memory usage
I think it is because Mac OS is smarter using physical memory and virtual memory. I always have much greater memory usage on linux than on mac for the same WO app... 2012/6/23 Pascal Robert prob...@macti.ca: Le 2012-06-22 à 13:00, Ron Lift a écrit : I want to thank everyone for the wiki on Deploying on linux at http://wiki.wocommunity.org/display/WO/Deploying+on+Linux It has been a great help. I am running into a memory issue that puzzles me and was wondering if anyone has some insight. I have my application deployed on RHEL6, 64 bit, Java 1.6 .33 running on VMware. When I look at the memory usage after the server is rebooted, no users have accessed the application, each instance is using @ 700meg. The strange thing is before I had the operations department build the server, I created a CentOS 6.2 64 bit on my MBP laptop to test. I can take the same application, deploy it and the memory usage is @ 110 meg. I then deployed the app on our OSX server, 110 meg. Any ideas what could be different or what I could look at? The difference might be in the version (client vs server, 32 bit vs 64 bit) I assume you have a 64 bit JVM everywhere? Same JVM version everywhere? You can check if you are running the JVM as a server by calling java version: $ java -version java version 1.6.0_33 Java(TM) SE Runtime Environment (build 1.6.0_33-b03-424-11M3720) Java HotSpot(TM) 64-Bit Server VM (build 20.8-b03-424, mixed mode) But still, a 590 MB difference is huge.

Re: Concurrent request handling
Hello again. I did turn on concurrent request handling. And now I have some issue with ec locking. I have subclassed EOEditingContext and this subclass posts alerts to the log when a thread attempts to lock ec that was already locked with another thread. And now I have a log full of such messages. I thought it was me to somehow make a mess to locking. But those log messages contain stack traces. And they show that ec was locked by MultiECLockManager on Session.awake() as it should have. And that the thread is trying to lock ec when doing ec.saveChanges() which action could not happen anywhere outside RRloop. How could that be that session is awaken by one thread and action is invoked by another within the same RRloop? Interesting thing is that users don't complain about deadlocks in App. Also I can see in log that they continue working (in the same session) after such issues. So I assume those issues don't cause deadlocks. However users do complain that the App is running slow sometimes. Maybe that is because of such local locks?

I am wondering whether to turn on concurrent request handling on my deployment or not. I always have this on. What are potential drawbacks of this? I assume there should be some.

I think these defaults were set to preserve existing behavior when new features were added. Unless you are sharing unlocked global writable data (from static ivars or Application), there is no reason to NOT have this on. If you are sharing unlocked global writable data, then you are Bad Person and should fix this! And another question: would concurrent request handling save me from global application deadlocks when one single request locks on exception? Maybe. It depends on why that session/request is deadlocking. I would focus on fixing that.

Time profiling

It is just default on my absolutely standard deployment system for WO (Xserve G4 , 2GB, MacOS X 10.5, Java 1.5.0_24) I found this 64M doing ps ax | grep java It lists all WO apps like this: /usr/bin/java -XX:NewSize=2m -Xmx64m -Xms32m -DWORootDirectory=/System ... If you look at the entire line, you will often see these set multiple times with different values. The last one is what is used. I could not find any other values set in that line... So Chuk, you also propose to raise this default? This causes me to ask another question. What is better scalability mechanism? Increasing memory for single instance or adding extra instances? Raising memory seems more resource effective. So why would I use multiple instances on single server? Or such means are some kind of rudiment? Gennady ___ Do not post admin requests to the list.

Re: Memory control
Hi, Finally at about 95 hours I get OutOfMemory error as the heap is limited by default to 64M. 64M seems small to me for a Java app. I did not do any memory regulations myself. It is just default on my absolutely standard deployment system for WO (Xserve G4 , 2GB, MacOS X 10.5, Java 1.5.0_24) I found this 64M doing ps ax | grep java It lists all WO apps like this: /usr/bin/java -XX:NewSize=2m -Xmx64m -Xms32m -DWORootDirectory=/System ... So as I understand -Xmx64m - that is maximum heap size. Actual memory usage for whole JVM is about 300M. So my question is - what should I do now? Is it expected behavior for large WO application? Using 64M+ of memory is, the increasing heap size is not. What are other means to increase memory used? Or such behavior should be considered as my error somewhere in code? So where should I look for memory leaks? You mentioned before exceptions, that is where I would start. Also check that your session sleep(), awake(), and terminate() can never throw an exception. If you are getting deadlocked sessions, then the session, page cache, and related EOs will never get garbage collected. Most exceptions I get now are cased by java.lang.OutOfMemoryError: Java heap space So that is what I am trying to get rid of. I get any other exceptions not more often than once a month whereas OutOfMemoryError comes nearly every 5th day =( Also check that your session sleep(), awake(), and terminate() can never throw an exception. Would I see such exceptions in log if they happen? I did not see any yet. Beyond that, I would try a heap analyzer to see what the objects are that do not get collected. What is heap analyzer ?

Re: Memory control
Hello again everybody. I still hope somebody would answer. I'va made GC logging with -XX:+PrintGCDetails and I see some interesting things happening. It seems like some uncollectable garbage is being accumulated in memory. Within the first hour heap usage goes up 35M and then within next 6 hours falls back to that number after rare fullGC acts. After 8 hours that lower limit goes up to 40M, after 20 hours - to 45M and fullGC acts happen significantly more often. After 30 hours heap usage would not fall lower 50M and after 35 hours almost every GC is fullGC. Since 60 hour lowest heap usage is 55M. Finally at about 95 hours I get OutOfMemory error as the heap is limited by default to 64M. So my question is - what should I do now? Is it expected behavior for large WO application? Should I simply rise max heap limit to find memory amount that would be enough? Should I schedule WOMonitor to restart the App every night? Or such behavior should be considered as my error somewhere in code? So where should I look for memory leaks? 2011/3/3 Gennady Kushnir genk...@rujel.net: Hello All! I would raise this topic again.

Re: Concurrent request handling
Hello all ! I am wondering whether to turn on concurrent request handling on my deployment or not. I always have this on. What are potential drawbacks of this? I assume there should be some. Why would it be off by default otherwise? I could not find anything interesting on this in documentation. WebObjects has several defaults that are not what most people would want. I think these defaults were set to preserve existing behavior when new features were added. Unless you are sharing unlocked global writable data (from static ivars or Application), there is no reason to NOT have this on. If you are sharing unlocked global writable data, then you are Bad Person and should fix this! Thank you for explanation. I think, I'll turn it on then. I hope I'm not that bad :-) And another question: would concurrent request handling save me from global application deadlocks when one single request locks on exception? Maybe. It depends on why that session/request is deadlocking. I would focus on fixing that. There is a theorem that every code has at least one error. And consequently it has unlimited number of errors. My code is several tens thousand rows written on different stages of my understanding of WebObjects Tao. Deadlock happen after some errors as ECs don't get unlocked after those unexpected throwings. Especially after Out of memory error that can not be captured. Gennady ___ Do not post admin requests to the list. They will be ignored.

Thank you. Sorry for long delay after your responses. Simply setting SetOutputFilter DEFLATE also did work for me. previously I tried AddOutputFilterByType DEFLATE text/html ...etc...

Thank you for these tips The point is that I do use multiple EOF stacks. I clearly admit that each EOObjectStoreCoordinator gets its own set of db connections. It only needs a single connection to work. Let's say single connection for each used database ;) In fact that is a goal I'd like to achieve to have a single connection for a EOF stack per database. That is what should happen *if* the connection dictionaries are equals() and you close the jdbc2info connections. Hmm. I'll put some more research into it. Strangely I do have multiple connections yet. I should find what ruins equality... if it is so I use separate EOF stack to access previous year data stored in a separate database with identical structure. That is why I employ EODatabaseContext.forceConnectionWithModel(model,connectionDict,ec) And that is why my models get identical connection dictionary. I am not sure if that is the best / right way to do this. I did not find any other method to connect a model do different databases. You need to create a new model group for the new EOF stack (the one using data from previous years), add the models, and update the connection dictionaries before using the EOF stack. I'not sure I got it right. I'm using the same models to access different databases. Should I clone them and place copies to another model group? So the modelGroup is going to be the root of EOF stack, not the DatabaseContext this time? And by the way, what is this method intended for after all? ___ Do not post admin requests to the list.

May be that is aforementioned JDBCinfo connection? Maybe or it could be a side effect or misuse of that method. Are the models already connected in the new EOF stack before you call this? No, they are not connected. I call this in Application constructor. And also this method is the only place where models get correct connection dictionary.

A db context can handle multiple models (the connection information needs to be the same). How can single db context handle multiple models ? I see that EODatabaseContext.forceConnectionWithModel(model,cd,ec) returns different objects for different models, whereas most of my models point to the same database with the same connection dictionary. And would it make sense to somehow force all these models to single db context? Is there a default number of EODatabaseChannels opened when the app starts up? Is there a configuration setting that I can set to add more? One per db context and no. My problem is that I see my app opening more connections than a number of models it has. And those connections do not close even after more than an hour not used. And it does not reuse all of them for later requests but may create even more connections. As a result when running multiple instances on a server with limited DB-connections I do get too many connections error sometimes. How could I fight it?

Re: Avoiding java.lang.OutOfMemoryError: Java heap space
Thanks to all.
Susanne, in fact my background pages should not be stored because I
initialize my dummyContext to deny page storing:
WOContext dummyContext = new WOContext(request) {
public boolean shouldNotStorePageInBacktrackCache() {
return true;
}
};
I have tested this and mentioned that whereas WOSession.savePage() is
invoked for my page
but savePageInPageCache() is actually not. So I assume the page is not
actually saved.
Farrukh, I've added EOEditingContext creation and dispose() into the
loop. It did help, thank you.
But I thought that editing context does not hold strong references to
its objects and so unnecessary ones should be garbage collected...
Well whereas I'm happy that my code is working right now I'm still not
sure that such problems won't revive once.
Could anyone suggest how to keep track of memory usage in my
application and how to tell what is consuming memory in the moment.

2010/6/23 Susanne Schneider susanne.schnei...@interactive-systems.de:
Hi Gennady,
we are doing similar background tasks here. To avoid memory problems we
declared the generated HTML pages not to be stored into the page cache. This
background pages implement the Interface IASUnsaveablePage:
public interface IASUnsaveablePage {
/**
* defines if this page should be saved in the WO page cache
*
* @return returning true is the same as not implementing
* the interface
*/
public boolean shouldBeSavedInPageCache();
}
and in our custom session class we override savePage():
/**
* implements the meachanism for the IASUnsaveablePage
*
* @see IASUnsaveablePage#shouldBeSavedInPageCache()
*/
�...@override
public void savePage(WOComponent page) {
if (!(page instanceof IASUnsaveablePage)
|| ((IASUnsaveablePage) page).shouldBeSavedInPageCache()) {
super.savePage(page);
}
}
Maybe you could use a similar approach?

Hello List!
I have a task to form an archive of a good bunch of WO-generated HTML
pages to HDD.
To achieve this I create a background thread to perform the task.
In this thread I create a dummy WOContext :
WOApplication app = WOApplication.application();
String dummyUrl = app.cgiAdaptorURL() + / + app.name() +
.woa/wa/dummy;
if(ses != null) {
dummyUrl = dummyUrl + ?wosid= + ses.sessionID();
}
WORequest request = app.createRequest( GET, dummyUrl,
HTTP/1.0,
null, null, null);
WOContext dummyContext = new WOContext(request) {
public boolean shouldNotStorePageInBacktrackCache()
{
return true;
}
}
After that in a loop I prepare my pages (in fact there are several
WOComponent's in work):
WOComponent page =
WOApplication.application().pageWithName(MyPageName, dummyContext);
and write them to HDD:
NSData content = page.generateResponse().content();
content.writeToStream(fileOutputStream);
The problem is that when the loop is long and the page contents is
complex my JVM runs out of memory.
What am I doing wrong? It seems like WO is storing something
unnecessary, how should I tell it to forget that?
At least how can I diagnose what exactly the memory is filled with?

Current licensing policy
Hello all! I have a legal question as I'm gong to distribute my WO-application wider than in my single organization. And most installations are going to be on Linux. And I'm not quite sure that Apple allows me to do that. We want one Linux distribution holders to include my project into their repository, but they are strict that everything in repository should be legally clean. The last bit of license regarding WO I have seen was in WO 5.4.3 Update installer. It stated that I can distribute WO libraries as a part of product. Well, I guess that's just fine. But it was 1.5 year ago... ... also it says that I can distribute it only for use by end-users - does it mean I can't give it out for inclusion into repository? Can anybody say what is Apple's current politics about WO? From my own research: WO is never mentioned on front pages of their website (since it was removed from X Server). The only place where it cal be found now is http://developer.apple.com/tools/webobjects/index.html Apple's current reference library does not contain ANY official documentation for WO. However it still can be accessed by old direct links that redirect to Obsolete section of library. And that documentation is really obsolete in fact - telling about developing in Xcode. So it seems like Apple does not have ANY public policy about WO. And that results into legal problems to us... It seems to me that today Apple just uses those libraries as a base for their stores and they have no reason to release any updates to it for us. Their shops are so cool full of AJAX and other stuff... I hardly believe they still use that primitive Component Actions Request Handler unmodified to make it.

Maybe if you are using them incorrectly.
Unfortunately I have no idea how to isolate a problem. I can not even
reproduce it.
Myself I have only seen it once in action. Mostly I can only see it
in logs. And I can't afford to limit functionality of a working
system.
Furthermore I assume it is in the most actively employed part of a
system. As most errors take place there. But maybe it is only because
the majority of saves are performed there...
Maybe I could diagnose the problem injecting some testing somewhere?
Maybe in editingContext subclass?
I'd start by taking a careful look at the full exception stack traces to see
if you can isolate where this is happening and then go back and very
carefully review that code.
After that, you would need to start disassembling the Java to see where
things go wrong and try and get some information logged out. That may
require replacing parts of EOF. This is far easier with Wonder but it is
still not easy. I have had the most success by carefully looking at the
code after looking at the stack traces.

These errors raise without any visible dependencies.
Users report that even when system says that it could not save

Something else is happening in your code then. Perhaps this is not
from
a save? Nothing should get written to the database if this happens
during a
saveChanges. Maybe this is happening in your app just after
saveChanges()?
Hmmm ... half-saving transactions is a common problem when you

I don't think that will cause this problem.
That's too sad... I did hope I found a fault...
It looks like direct violation of commandment to avoid modification of
returned values in getter methods.
Well anyway, I think I'll get rid of it and see what happens. Sadly I
can not give up searching my code for such faults...
And another guess: fetching from the same ec for setting default
values in awakeFromInsertion?
That is OK.
In fact I'm glad to hear that. I wouldn't like to look for alternative
solutions.

Maybe if you are using them incorrectly.
Unfortunately I have no idea how to isolate a problem. I can not even
reproduce it.
Myself I have only seen it once in action. Mostly I can only see it
in logs. And I can't afford to limit functionality of a working
system.
Furthermore I assume it is in the most actively employed part of a
system. As most errors take place there. But maybe it is only because
the majority of saves are performed there...
Maybe I could diagnose the problem injecting some testing somewhere?
Maybe in editingContext subclass?
I'd start by taking a careful look at the full exception stack traces to
see
if you can isolate where this is happening and then go back and very
carefully review that code.
After that, you would need to start disassembling the Java to see where
things go wrong and try and get some information logged out. That may
require replacing parts of EOF. This is far easier with Wonder but it is
still not easy. I have had the most success by carefully looking at the
code after looking at the stack traces.

Something else is happening in your code then. Perhaps this is not

Hmmm ... half-saving transactions is a common problem when you

available
when

I tried to find the source of error adding logging to awakeFromFetch

Re: EOModels occasionally loading too slowly?
Hi, Normally EOmodels are loaded on demand (when they are requested) you may force EModel to load calling EODatabaseContext.forceConnectionWithModel see API for details Regards, Gena 2009/11/3 Paul Hoadley pa...@logicsquad.net: Hello, I am using Wonder and extending ERXApplication, but I don't think this is Wonder-specific. WO 5.4.3. I have an app that loads 8 EOModels, 3 in the app's Resources folder, 5 in linked frameworks. The default page makes use of an entity in one of the models in an external framework. Every few runs, an exception is thrown before the first page can load: Error: java.lang.IllegalArgumentException: An object store for the entity Status could not be found. Verify that the entity is defined in an EOModel, and that the model is installed properly. To see what models are loaded, you can try printing the return value of EOModelGroup.defaultGroup() in your application. The problem appears to be that not all the models have loaded by the time that page is being displayed. Indeed, checking EOModelGroup.defaultGroup() shows between 1 and 4 or 5 of the 8 models have been loaded by the time that entity is needed on the default page. Sometimes the correct model has loaded, and the page is displayed. Other times it hasn't, and the app bails out with that error. By the time Application.didFinishLaunching() is called, they're all loaded. Are the models really being loaded asynchronously as the app launches? Is there some way I can force all of them to be loaded by the time the first page needs that specific entity? -- Paul. w http://logicsquad.net/ h http://paul.hoadley.name/ ___ Do not post admin requests to the list.

Re: Zero dates 0000-00-00
Thank you, ChukThis sounds intriguing. Something deep in EOF... I will experiment with this, but I can't find the best way to get the EOAdaptorChannel to set a delegate for it. Possibly intercepting it at the moment of creation. In fact I thought that was a common problem interacting with third party databases. And that there should exist some common solution... 2009/3/17 Chuck Hill ch...@global-village.net These are Java exceptions, not EOF exceptions. So this won't be easy... Look in EOAccess at the interface EOAdaptorChannel.Delegate. Specifically the adaptorChannelDidFetchRow method. You should be able to implement that, look for such values, and replace them with the null marker (or remove them, I don't recall the dictionary contents at this level). http://developer.apple.com/documentation/MacOSXServer/Reference/WO54_Reference/com/webobjects/eoaccess/EOAdaptorChannel.Delegate.html#adaptorChannelDidFetchRow(com.webobjects.eoaccess.EOAdaptorChannel,%20com.webobjects.foundation.NSMutableDictionary) I don't recall offhand how to set the delegate. I thought there was a notification, but I could not find it.

Re: directActionURLForActionNamed produce corrupted hostname
Hello I have the same problem and this annoys me much. I seems an unexpected behavior to me to generate complete URLs including hostname when I don't ask for that. Also even when adding host name it would better take value from host header instead of server_name header. As host represents actual url in browser while server_name displays what a server intends to be, which would be wrong when working on local network with private IPs.

I was just hoping for it to be solved in 5.4.2 until now). I have a layout page, using a couple of URL to direct actions. I generate those using the method : WOContext.directActionURLForActionNamed(String anActionName, NSDictionaryString,Object queryDictionary) (or ERXWOContext.directActionURLForActionNamed(String anActionName, NSDictionaryString,Object queryDictionary, boolean includeSessionID), which directly calls super... implementation) When pages are sent through 'http' (non-secured), the generated URL is an absolute path, but no scheme or host. When pages are sent through 'https', the generated URL are full URLs, including scheme and hostname. This is working fine as long as I'm in development setup (Eclipse as IDE), but as soon as I deploy, when a page is sent through 'https' the host name gets 'corrupted', more precisely '_copy' is appended to the host name (whilst, when sent by 'http', the URL are absolute, withOUT scheme or hostname). I've even tried to use Eclipse on the same machine that is running the deployed application : this does not show the behaviour of the deployed application. I've also noted the exact same type of problem when using a WOHyperlink 'connected' to a directAction, with the 'secure' binding set to false, and the page is sent using 'https'. Clearly, I don't understand well enough the difference between the dev. environment and the deployment one (in my case 'classical' wotaskd/JavaMonitor). I've reported this bug with ID : 6055888 In the mean time I'd like to be at least able to reproduce this behaviour when running from Eclipse (to debug and get a better understanding of what's going wrong) and hopefully a workaround (which should be possible, given the Dev. environment manages to get these generated URLs as they should).

Making a fake EO
Hello list! I have rather complicated question: is it possible to make an Enterprise Object that does not relate to any specific existing row in database? I want it to indicate vacant employee places where on the other hand I don't want to store NULL. So I want relationships pointing to zero which is not real primary key for any row in database to return that fake EO in my WOapp. And vice-versa - when I assign a relationship to fake EO - then a related cell in database should get zero value (not null). And also I want to be able to search database for that value using EOF. Is it possible somehow? Or my only way is to create a real record in my employee database called Mr. Vacancy and maybe even pay him salary :) Thanks in advance Gennady ___ Do not post admin requests to the list.

Re: Making a fake EO
I thank everybody for you replies. Why don't you want to store null? Is this a situation where you don't have control over the DB? Is there a DBA that is trying to impose extreme normalization? I don't want null because on the other object in my database that may be related to some employee or unrelated to employee (with null foreign key) and also it may be related to vacant employee place. So I need some third option to indicate that aside from pointing to real employee or null. The other problem is that I am taking the list of employees from external database that is in use by another application which is not under my control. So it is undesirable to have that Mr. Vacancy in official reports. So I want relationships pointing to zero which is not real primary key for any row in database to return that fake EO in my WOapp. That is going to be very hard because EOF is automatically going to go to the Database to look up the instance that has a Primary Key of 0, and throw an error if it can't find it. It is possible with Wonder to have it just log the error and not terminate the application, but it is a scary hack if you are in control of the database. Well in fact I came across that several times. When there was no matching row row for foreign key EOF simply returned me an empty Enterprise Object with all attributes set to null. And the only place where I encountered an error was a NullPointerException when treating unexpectedly NULL attribute values. And maybe when saving. Well... by now I've only got that this is The Hard Way™ ... but no pointer to that way... Maybe I should consider some other ideas... ___ Do not post admin requests to the list. They will be ignored.

Obtaining newly generated primary keys during save
Hello, list I'm trying to get primary key value from one enterprise object to get stored in another table. But if the object is recently inserted it does not have any primary key and consequently I have nothing to save. I tried to trigger second tabe initialisation on EOGlobalID.GlobalIDChangedNotification but it seemes too late as changes made at that moment were not saved. I think there should be some solution as if you save several recently created related objects their relationship fields are properly initialised during save with newly generated primary keys. P.S. I do not want to use actual relationships from that table storing pKeys as it is not in fact a part of business logic but something like log and it stores primary keys from different tables in the same field p.p.s. I've seen a piece of code generating primary key before actual save on Wikibooks. I'm not shure, it is a good idea. If some (say validation) error occures on actual save, or if save is simply discarded afrewards, than that pregenerated key would not be emloyed ___ Do not post admin requests to the list.

Hi' all I've started experimenting with git recently. It required compiling as I'm not on Leopard yet. First I was confused, how to use it with Eclipse - what files from project to include and how to apply patch or rollback if needed (so that eclipse take this action into account). Then I installed eclipse plugin - it did help to add project files to repository and made it handy to review history and update repository. It is good not to add every changed file manually... but is it possible to store entire workspace in single repository? i work on main app and several frameworks simultanously maintaining separate repository for each does not look good idea... 2008/5/15 Robert Walker [EMAIL PROTECTED]: I just scanned though this thread and, unless I missed it, I didn't see any mention of Mercurial (hg for short). I recently stared using hg and have also begun experimenting with git. Both are really great and have some minor pros and cons between each other. But, IMHO either is far superior to SVN for my workflow and development style. SVN for me was a huge step up from CVS, which often made me want to shoot myself trying to resolve conflicts that other team members threw at me on a nearly daily basis. I have always hated the virtual tether that centralized SCM impose. If you not connected to your repository directly, you can't commit your changes. That drove me nuts every time I was working away from the office. Distributed SMS like hg or git make all those headaches go away. I can freely branch, commit, checkout or whatever all completely isolated from any central repository. It's really wonderful. Now for my thoughts on SCM plugins for IDEs: Frankly, I really don't care if they are there or not. I do all my repository work in one of the greatest tools ever invented; the UNIX command line. Nearly all IDE plugins for SCM are limited in a least some way. They don't tend to support everything you really need. The command line is different. Every feature the SMC system has to offer is available and there's no question of the maturity of some plugin. But, that's just me. :-) +2 hg +1 git -1 svn -999 cvs On May 14, 2008, at 2:54 PM, Chuck Hill wrote: On May 14, 2008, at 10:56 AM, Gennady Kushnir wrote: Are they hiring? :-P Russian citizens only. ;-) Ah well... someone wants to spend a workday without Internet? :-o I have an almost endless list of reading, writing, and experimenting that I would like to do.

Flattening relationshops (consequently - many-to-many relations) does not work across database (consequently - EOModel) boundaries Unfortunately. It is mentioned in Using EOModeler manual.

Application became sluggish when deployed on 5.4
Hello list I have an application which should display information from lots of enterprise objects (maybe several hundreds) on single page. When in development mode and when deployed on Tiger Server (WO 5.3.x) (on XServe dual G4) it worked fine with only reasonable lag of about 1 second. But when we upgraded to Leopard (and WO 5.4) my application became inadequately slow and now it takes about 7 seconds to load the same page on the same XServe. What is interesting - when run in development mode on Leopard (WO 5.4) everything works fine. So it is not a problem of generally 5.4 but specifically 5.4 Server. When deployed on experimental Mac OS X Server on my MacBook it also produced unreasonable lag about 3 seconds (of course Core 2 Duo is faster than G4). I tried to diagnose a problem and found that it does not produce bulk of unnecessary SQL requests (monitored by MySQL log) and no load to HDD (as shown by Activity Monitor). But it produces heavy CPU load - so it is all related to some not optimal processes in memory. Any suggestions? Where should I concentrate with debugging? EOF of wo.appserver?

Versioning ... CVS or Subversion?
Hello list. I'm thinking about using some versioning system. Trying to decide whether I do need one and if yes - which one. I've heard something about CVS and Subversion. Maybe there is some other... What are advantages and disadvantages of versioning in general and of concrete solutions. I work on Eclipse, I've seen it does support some versioning. Today I just zip my workspace and put it on my flashdrive. As I work both at home and at work I have to synchronise my work. In most cases when i come home I just trash my obsolette workspace and unzip the one I brought from work. But this approach has disadvantages... first - the whole workspace (even zipped) consumes rather much disk space (a lot more than just source codes) so my version repository bosomes very large - when I used xCode it was much more compact as I excluded build folder. and second - if I forget to zip workspace and put it to my flashdrive - than if do something after that - I have to thoroughly merge my work after that. Will versioning sistem help with these problems? Another point is that today I work alone. But maybe in future I will find some collaborator. As i understand - vesioning should help in group work.

Re: Versioning ... CVS or Subversion?
Thank you all for your opinions. I see all hands are for SVN except built in Eclipse integration. Maybe I should have used google, but could you explain me in general how does versioning work. And how do I work with it. Specifically in regard to WO development. Does it archive only java sources? And how about components, EOmodels and other related resources (which can also have versions)? Another condition is that I don't have Internet connection at work so I can't use online repository and have to merge my homework using flash drive anyway. Does versioning system support this?(and which ones do?) And questions to Miguel: - where I can find that very good open source book that documents everything ? - I can't imagine versioning system without IDE integration. how does it work? - If you say it is that good with Mac OS X integration and coming really soon - maybe I could wait a bit and start my versioning experience with something really cool?

Yes, do DO need a version control system. Zipping and flash drives are an excellent way to burn yourself with mistakes and lossing work. There are some more version control systems, namely GIT. I still didn't look at it. It's the system used to manage the Linux kernel source code, and people say it basically can do anything (which might be good or bad). Specially, merging several code forks seems to be easier than CVS and SVN. Anyway, between SVN and CVS, you want SVN, period! Let's say that, the first time I used a version control system (and that was CVS) I only committed stuff with other people looking over my shoulder to make sure I was not going to screw things up. CVS just doesn't make any sense, at least for me, there are too many things that are not done the way they should. On the contrary, SVN is what CVS should have been. It's clean, it works. The main difference is that SVN considers a version to be the state of all the files tree. IE, you know that version 234 of your code repository means ALL the tree is in the version 234, it's like a snapshot in time. CVS uses a different and independent version number per file, which makes things chaotic. You may have a file in version 25 (because you changed it 25 times) and another file in version 3 (you changed it 3 times) that were actually added to the rep at the same time. It just doesn't make any sense, again, at least for me. Also, SVN has a very good open source book that documents everything. About IDE integration and software, I don't use the eclipse plugins, because I'm lucky enough to be a alfa-beta-whatever-user of a new GUI for SVN that is coming on for Mac OS X really soon now, and that I simply love.

But when I tried to build and my project I bumped into ClassLoadedException: Application class not found When I had a look at build results i astonishingly found that inside woa bundle there are no Resources nor WebServerResoures folders. But they are replaced with one of the files that should have been inside them... Instead of Resources folder there is WOAfile.icns (named Resources) and named WebServerResources - one of my png images in project. Certainly it seemes absolutely impossible to run that project...

Sending mail is to be scheduled - so when performing the task I don't have WOContext - it is not initialised with WORequest - because there is no request when in scheduled action.

Which way is more efficient to get particular EOEnterpriseObject
Hello, List It is not an unresolvable problem. However I just want to perform tasks in the most efficient way. I have a to-many relationship, which points to rather large (about 100) heap of objects. I need to get one of these objects - which one depends on some other attributes of one (or get null if there isn't one that match). And I have to take them that way one by one and possibly do that with all of them. This is done while placing info from these objects to the appropriate place on page. In fact I have something like multidimensional (3) array of objects. The question is - which method for performing that task is the most efficient in WebObject framework? Ideas I have so far: - cycle through array (which I get from relationship attribute), checking if attributes match - construct EOQualifier and filter the array with it - just fetch required object regarding mentioned relationship as just one of attributes involved - index that array converting it into actual multi-dimensional as mentioned above (using pure Java multidimensional arrays or nesting NSArrays/NSDictionaries) Sorting wil not do as the order in which objects will be needed is uneasy to predict Also this is not immutable and other objects into the array may appear - so I want to have them on their place immediately.

Re: Which way is more efficient to get particular EOEnterpriseObject
With a hundred objects, that is quite okay. If you have to do it multiple times, it might be an idea to convert it into a dictionary and base the keys on the attributes you're looking for - if that is doable. You haven't given enough information here. In fact, building a dictionary - it is what I ment by indexing. Maybe that's not correct to call it so. - just fetch required object regarding mentioned relationship as just one of attributes involved If your array grows to a size that a linear scan or a building a hashtable (dictionary) is to expensive, a database roundtrip might be the fastest way if you can use indexes for everything. Only for that HUUGE arrays? I thowght, that caching of objects, that EOF do shoud significally speed up fetches... Will it do real database roundtrip for fetching an object that's already cached in memory? (I know it is, as it is in that array in relationship attribute) And the other thing is: implement it in the easiest possible way, so you don't waste resources on it and see whether it is actually too slow. Never optimize anything that doesn't need optimization. Use the simplest code you can write to get the job done and optimize only, if that is too slow. Developer time is normally much more expensive than CPU time. Thank you for that advice, I'll take it into accont )) In fact when I'm trying to opimise I optimise both CPU and developer time. In this particut=lar case - it would be much easier to utilise a structured hashtable than to write a cycle or qualifier each time I mant to get something from that unstructured array. Thank you all who replied. I think I'll buld a hashtable on demand (when this kind of query is first required). Gennady ___ Do not post admin requests to the list. They will be ignored.

Re: EOUtilities.primaryKeyForObject
Hi, I've bumped into this several times. The problem is that enterprise objects do NOT have any primary key right after creation until they are saved into database. So when you create new instance of enterprise object (new record into database) you should run EditingContext.saveChanges() before you can access the primary key of you object.

On further investigation I have realised that the Customer object is not being saved at all, it appears as though it is unable to get a Primary Key for the record as it saves it. The EO_PK_TABLE appears fine and all other tables save with no problem. I wonder does anyone have any idea where I should look to find the problem, I have checked everything and it all looks as it did before.

I assume, making your first (login) page DirectAction should help.

Re: auto-zip on upload

Re: unkown exception
The ultimate resolution to most sensless problems like this is Clean all targets (in menu under build button, when hold for a second or two). especially - for WO 5.3.x or even more radical method is to delete build folder in your project folder.

I'll edit the file, build and go, and the application doesn't seem to see the keys and actions that I added to the files.

Re: how to set value?
hello if you have created custom class OpportunityCompany.java then look into this .java file to see which datatype is taken as attribute for setPrimaryCustomer(). Most possibe is Boolean or Number. These are wrapper classes while true and 1 are primitive data types. You should use Bootean.TRUE or new Integer(1) if you haven't created that custom class, you can't use method setPrimaryCustomer() as there isn't one. then you should use universal method, applicable in any case: takeValueForKey(Boolean.TRUE , primaryCustomer ); Regards, Gennady in my OpportunityCompany entity, i have an attribute primaryCustomer. this attribute is of external type boolean, and value class(java) Number. Therefore it's setPrimaryCustomer() in the java file is a Number data type. but i can't seem to pass a 1 or true to it when i try aOpportunityCompany.setPrimaryCustomer(1) or aOpportunityCompany.setPrimaryCustomer(true). So how can I do it? Warmest Regards, Jim Wong [EMAIL PROTECTED] ___ Do not post admin requests to the list. They will be ignored.

Using information from LDAP, JNDI adaptor
Hello, list. In the applicatin i'm planning to create i want to use LDAP (eDirectory) to manage user login and access privileges to modules and objects of my WO App. As i understand JNDI adaptor is intended to deal with LDAP. However i can't find any usable manual how to use LDAP and JNDI in WebObjects. The only useful thing i saw was authentication using LDAP (in Practical Web Objects). But it had nothig to do with JNDI. I think if JNDI option was included in WebObjects dialogs (when creating EOModel) there should be some instruments to work with it. Did any of yoiu have any experience with this point or maybe you could point some useful URL. Thanks in advance. Gennady Kushnir ___ Do not post admin requests to the list. They will be ignored.
