Re: Get server host from request or url
Chuck Hill wrote:
Hello Benoit,
How are you handling sessions? When the Flash client requests a web
service, what URL does it use?
Hello Chuck,
Sessions id are transferred to flash client as a flash variable, as well
as server FQDN. Sessions are then restored on the server.
Eventually, problem is solved.
Swf file was loaded from an url, let's say url_1. My webobjects server
sent back a server name from method serverNameFromRequest(WORequest
request). This server name returned was then concatenated to a port
number on the flash client. This returned a new url (url_2) which is
used to get web services wsdls. The problem was that url_1 and url_2
host parts differed, so that the Flash Player tried to get a
crossdomain.xml on the second host (something like
my.local.computer:2002/crossdomain.xml, 2002 is my web services port).
Of course, this returned a 404 status code which made my aplication hang up.
I just simplified my method :
>> public String serverNameFromRequest(WORequest request) {
>> return request.headerForKey("host");
>>
>> }
I am now sure that url_1 and url_2 are the same. Everything seems to
work now :)
Thanks Chuck !

Here is the method involved on the server in returning the host name.
public String serverNameFromRequest(WORequest request) {
String s = request.headerForKey("x-webobjects-server-name");
if (s == null) {
s = request.headerForKey("server_name");

s = WOApplication.application().host();
}
return s;
Does anybody ever have this problem ? Any help is appreciated.
Thank you.

Re: Performance problem before and after growing WOWorkerThreads number
Chuck Hill wrote: Hi Benoit, Hi Chuck, Thank you for your reply. On Jun 8, 2007, at 11:24 AM, Benoit Cantin wrote: On one of our apps, we have what I describe in the subject. The growing worker threads is not the problem It is just a symptom of the problem. Application runs on xserve dual G5 and wo 5.3.3. Only one instance, multithread disabled. Adaptor settings are given in the attachement (sorry for this). The workflow is the following : only 3 users connect to the webobjects backend through one direct action. In this direct action, there is a call to the the session().defaulteditingcontext() method initiating the creation of a session. That is what I understand from the doc. Just calling session() is sufficient. OK. As our DAs don't need to maintain an active session to do their job, we decided to switch to a new EOEditingContext() and to manage lock and unlock as described in the wikibooks http://en.wikibooks.org/wiki/Programming:WebObjects/EOF/Using_EOF/Context_and_Database_Locking Now we come to about 250 sessions created, then log says : [2007-06-08 19:54:00 CEST] : Growing number of WOWorkerThreads to 32 That is a symptom of a bug in your application. Having more than 16 worker threads is either a sign of a bug, or an indication that you need to run more instances as load is too high. But just before and after, application becomes slw. It processes one request a minute and then application becomes unreachable. It is the slowness that is causing the extra worker threads to be created. You need to find why it is getting slow. I suspect that your sessions are not terminating properly and that memory is running out and the app is spending too much time doing garbage collection. If could be a deadlock, but then the app should just stop responding, not get slow. So that's not a deadlock since app doesn't stop responding. And you are right about memory running out. Now that we have made a couple of amendments (especially on DAs), this trouble seems to have been solved. Until now, we couldn't add more instances due to optimistic locking problems. We are confident for this to be quickly solved too. Once this will be done, we will add more instances, and we hope that slowness problems will be definitely solved. My question is : from where does this problem come from ? Can this be from WODefaultAdaptor settings which I didn't modify ? sessions in direct action ? Anything else. Please let me know if you have ideas or wish any other info. Check the app log for exceptions. Have you overridden awake, sleep, or terminate in the Session class? Don't let those methods throw any exceptions! We have not overridden theses methods. Thanks Chuck. -- Benoit Cantin ___ Do not post admin requests to the list. They will be ignored.

Re: api variables
First of all, thank you for your answer. I am working on the same project (a CMS). Hi, Laetitia, On Sep 4, 2006, at 5:45 PM, Laetitia Orsini wrote: Hello, I'm a newbie and after having developed my first "complex" webobjects application I wonder if it was the right way to do it... The aim of the application is to offer an interface to manage contents stocked in a database. I have at the end many reusable web components with many api variables. Within these api variables I send the edited objects and a lot of booleans to deal with the layout with conditionals. Is it a common way to do things in a web objects application ? Doesn't it look like dirty javascript ? It's not clear what you're asking here. However, it sounds like you may be trying to do some things that WebObjects (WO) would do for you more easily if you would let it. Here is an example of what we are doing. An entity called "Artist" references instances of an entity called "Album". We have 2 Web components, one which let users customize Artist properties, let's call it component1, and the other which let users customize Album properties (component2). Both components are reusable ones. Main component defines an instance of component1, and component1 defines an instance of component2. A variable called "theEditedArtist" is passed from Main to component1, and to component2 as an API variable. The reason is that we must get modification on "theEditedArtist" made in component2 back to Main. Identically, Boolean API variables are passed to component1 from Main to enable/disable blocks visibility in component1. Other Boolean API variables are passed from Main to component2 (which is attainable from Main and component1). You guess that those Boolean variables are passed from component1 to component2. These API variables must be in a coherent state, since they control component1 and component2 display, themselves displaying on the same screen area. So the problem is to maintain Boolean coherency, otherwise : -if all Booleans are set to false : no display. -if all Booleans are set to true : multiple overlaying displayed components. It might help to review an example. Take a look, for instance, at the ThinkMovies example at: /Developer/Examples/JavaWebObjects/ThinkMovies/ This application also uses the JavaBusinessLogic framework whose source code you can find at: /Developer/Examples/JavaWebObjects/Frameworks/JavaBusinessLogic/ In order to build and run the example, you will also need to start the WOMovies OpenBase database, but you can review the code and WO Components without doing that, if you don't wish to take the trouble to build the application. If you do want to build the app, Apple recommends that you copy the project to your own work area first, and not modify the code in the Examples directory. What are the differences between api variables and non synchronized variables ? Thank you for the tip. I think it doesn't simplify our design. If my understanding is good, they define MovieComponent in order to share movie variable declaration and other static variables definitions. But it doesn't answer our synchronization need. Good ? The api variables for a component may be synchronized or non-synchronized. Synchronized, means that WO will push any variable values through the api variable bindings from the parent to the child component, then pull the values from the child component back to the parent component both before and after each of the Request/Response loop method calls (appendToResponse, takeValuesFromRequest and invokeAction). That means that the values will be pushed downward and pulled upward across the component/subcomponent interface six times for each page rendering and user response to the page. Though this approach is not particularly efficient, it tends to keep people new to WO out of trouble. To make the value transfers more efficient, you can override the synchronizesVariablesWithBindings method in your subcomponent to return false, which will stop WO from doing the six push/pulls for you. In that case, you will probably use the WOComponent valueForBinding and setValueForBinding methods to push and pull the values yourself. Although this is more efficient, it is also more work on your part. For a small, local, low traffic, administrative application (e.g. an app that will be used by fewer than 10 or 20 people each day on the LAN), I probably would let WO synchronize the values. So API variables sounds good in our case. I also wonder if this kind of applications would be more quickly implemented with Direct To Web. I've made some tests with Direct To Web on my database model but it seams I'll still have a lot of work to customize things if I want the same features as in my own application. For example, if I have an entity Album that contains Singles, I would like to be able to edit Singles just by clicking on a Single listed in my edited Album. This
Many questions about SCM and svn in XCode
Hello, I use SCM in XCode with svn, but it is not always as simple as I would like it to be. First of all, what is the difference between options "update entire project" and "refresh entire project" ? Many times, I got this kind of error "svn: Out of date: 'test.eomodeld/test.plist' in transaction '19-1'" when comitting from svn client in console (I sometimes commit from console since SCM fails in XCode just saying "Commit failed" with no detail). Any suggestion (it's not really WO, but you may have an idea). I can solve conflicts on java file as well as on eomodels files. But how can you solve conflicts on project file ? Currently, most of the time, conflict on project file is leading me to a deadlock. As a result, I have to create a new project and copy all my Web Components, etc... I wonder if I not going to use Eclipse instead of XCode for forthcoming projects due to SCM problems. Thank you, -- Benoit ___ Do not post admin requests to the list. They will be ignored.
