Re: Passing a wrapper component to a page-level component
Hello Paul; Did you end up taking a look through the LEWOStuff page/navigation architecture in the end? No need to use it directly, but you may potentially get some design ideas. It sounds like some of what you are trying I have already worked through. I keep a stack structure of page states off the session (instead of using the context's info dictionary) and these are called navigation destinations or ND-s for short. NDs are KVC-compliant and act a bit like a dictionary to store state in. Having said this, for sanity, I *always* access this data through a structured component controller and *never* directly from the ND. The ND's are also able to express the component name to swap over in the WOSwitchComponent like you mention you are doing. The NDs are conveniently able to be formed into a tree to provide a data structure for menus and exist in a stack off the session which forms the breadcrumbs for historical navigation. The architecture does have a couple of things that one ought to watch, but it works very well in practise. cheers. So I rolled my own solution. EditFooPage has a WOSwitchComponent as its outermost element. The app-specific LAF class is passed to EditFooPage after construction so that it knows what to substitute for the WOSwitchComponent. Key-value pairs are stored in context().userInfo() to simulate the bindings intended for LAF. The keys are in a namespace specific to the app-specific LAF, which knows to look for them and change its behaviour accordingly. Of course, context() disappears at the end of the transaction, so if LAF finds key-values in userInfo(), it also caches them locally for reuse if required. It works, but I feel dirty.

I do like the design. However, it's the practical details that are killing me at the moment. It sounds like some of what you are trying I have already worked through.

Re: Making the EOModel to work with LDAP
Hello. I have read the chapter again, and saw the example once more. but the model it's not set up to use LDAP. As I see, it has an Entity called LDAPAuthenticatedUser which inherit from abstractUser, but the whole EOModel it's set up to work with FrontBase. Now, I see in the implementation of the LDAPAuthenticatedUser, and as I said, it has coded the DN and url of the LDAP inside the custom .java class, not the _LDAPAuthenticatedUser .java. I have been searching on internet, and saw many post of people saying that I can't set up a many-to-many relationship for a LDAP model. So I don't get it on how to do the model, which attributes should I put for each entity. I understand how the Object graph it's build when using a SQL db, and how to fetch is done, I re-read the EnterpirseObject programming guide again :P. but no LDAP example. Authenticated as the book shows is done, but now to fetch the data, what should I do?. I fetch some data using the search(...) method of the DirContext class, and seting up a filter, but then Im not using any EOModel at all.

Re: Making the EOModel to work with LDAP
Hello all again.

Right after this, it says By default, reverse engenieer sets the relativeDistinguishedName attribute to be neither a class property nor and attribute that participates in locking first, if I have the LDAP server running with its own schema, how can I do reverse engineering of it?. Now something else. where is the Custom Formating inspecotr in EOModeler, due that this is a method they suggest to create the rdn, but its kind complicated, I don't get it. there is another method, that is to set the rdn as a class property so I can read it, and then I can genereate the new rdn.

I think if you do something like this in a D2WComponent named 'MyD2WComponentWrapper' wo:WOSwitchComponent componentName=$pageWrapperNamewo:EditFooPage // wo:WOSwitchComponent and set up a rule like 100: task = 'edit' and entity.name = 'Foo' = pageName = MyD2WComponentWrapper and generate the page in your app by using D2W.editPageForEntityNamed ... then I think it should work and you should be able to pass bindings to your wrapper via the d2wContext using the rule system. As I've mentioned earlier, I've never tried this without using a real D2WPage. Perhaps you tried this already and ran into something else? Thanks---the information above was the extra kick along I needed. This seems to work, and is obviously slightly neater and more conventional than my home-brew approach. Because I have control over the external frameworks, I've changed EditFooPage directly to extend D2WPage, implement EditPageInterface, and switch in the supplied page wrapper itself. So where you've got MyD2WComponentWrapper above, I use EditFooPage itself. I can then pass key-value pairs to the LAF via d2wContext, and LAF will look for them if d2wContext is available, in much the same way as the code you recommended looking at in ERD2WHead.

Re: can't create WOComponent
Hi Ted, When you create a Component, it also creates a .java file to go with it in your Sources directory. You must manually delete that file if you delete the Component. The New WebObjects Component window sees that file and assumes you haven't deleted the component. It should just say that there is a .java file with that name instead of a Component. Good news is that it is a simple fix. Dave On May 7, 2009, at 12:43 PM, Theodore Petrosky wrote: I created a new WOComponent then deleted it. (right click = select Delete).

Re: No snapshot for gid _EOIntegralKeyGlobalID
Just glancing at the stack trace there a few things that I would look for. You are using EC in threads? This is usually hard to get right as you need to have the EC lock before you fire any faults and you don't want to create deadlocks between threads. How many thread to you have that access the DB? Could you have one DB connexion per thread? In this case I would create one EOF stack per thread and lock the stack when processing starts and unlock it at the end, this is by far the easiest model. Do you transfer EO from one thread to the other? Pierre -- Pierre Frisch pie...@apple.com On May 7, 2009, at 9:47, David Avendasora wrote: Hi Pierre! Glad to see you active on the lists again!

Virtual host deployment question
Hello, So I have everything working on my deployment server. Two independent pairs of wotaskd and womonitor along with separate siteconfig.xml files. Everything seems to be working properly . My last bit of configuration needs to restrict access of a WO app to just one virtual domain. For example www.a.com/cgi-bin/WebObjects/A.woa www.b.com/cgi-bin/WebObjects/B.woa . Right now I can access both WO apps from either domain. Is there a straightforward way of implementing this restriction? I have already attempted it by moving the WebObjectsConfig http://localhost:1085 10 directive within the virtual host configuration file and limiting which wotaskd it can see. This did not work. If anyone has any time tested solution for this I would be grateful. Thanks Mitch ___ Do not post admin requests to the list. They will be ignored.

This is usually hard to get right as you need to have the EC lock before you fire any faults and you don't want to create deadlocks between threads. How many thread to you have that access the DB? Quartz right now is configured with 5 threads in the thread pool (it's the default) but in practical terms there shouldn't be more than 2 active and working at any one time, and that should only happen occasionally. I only get the error occasionally, so it seems likely that this could be causing the problem. Could you have one DB connexion per thread? Are you suggesting that I should, or wondering if that is the current situation? RIght now, I believe both threads would be using the same DB connection. I'm certainly not setting up anything differently than the standard (default) WO app setup.

I would assume that Wonder's ERXObjectStoreCoordinatorPool is the best way to do this? this is by far the easiest model. Even easier: I'm going to just configure Quartz to use one thread.

Just glancing at the stack trace there a few things that I would
look for. You are using EC in threads?
Yeah. I'm using Quartz (http://www.opensymphony.com/quartz/) to do
some automated processing. Normally the jobs run at different times,
but it is possible for them to run simultaneously each using its own
thread.
This is usually hard to get right as you need to have the EC lock
before you fire any faults and you don't want to create deadlocks
between threads. How many thread to you have that access the DB?
Quartz right now is configured with 5 threads in the thread pool
(it's the default) but in practical terms there shouldn't be more
than 2 active and working at any one time, and that should only
happen occasionally. I only get the error occasionally, so it seems
likely that this could be causing the problem.
Also remember that ERXEC only auto-locks for request/response loops.
You are responsible for manually locking in background threads.
i.e., you _must_
public void run() {
ec.lock();
try {
// process
} finally {
ec.unlock();
}
}
Could you have one DB connexion per thread?
Are you suggesting that I should, or wondering if that is the
current situation? RIght now, I believe both threads would be using
the same DB connection. I'm certainly not setting up anything
differently than the standard (default) WO app setup.
In this case I would create one EOF stack per thread and lock the
stack when processing starts and unlock it at the end,
Okay. That makes sense. I would assume that Wonder's
ERXObjectStoreCoordinatorPool is the best way to do this?
this is by far the easiest model.
Even easier: I'm going to just configure Quartz to use one thread. I
think this way each job will just need to wait until the previous
job is finished before starting. I'll see how that works first, then
move onto multiple EOF stacks only if I really need them.
Do you transfer EO from one thread to the other?
Nope!
Thanks again!

Dave,
Which version of WO?
WO 5.3.3
DO you use shared editing context?
No.
Is there any chance that the Editing Context is not locked when
the faults fires?
Yes. After 5 years of doing WO (mostly D2JC), this is one of the
first places I've started using ECs other than the default EC, so
I'm sure I'm abusing it. I'm just not sure where to look to fix it.

You must manually delete that file if you delete the Component. The New WebObjects Component window sees that file and assumes you haven't deleted the component. It should just say that there is a .java file with that name instead of a Component. Good news is that it is a simple fix.

Many to Many with an ordered join table
Hi I'm sure I have a commonly seen issue: I have a many to many relationship between tables SOURCE and DEST. This is implemented by a third table GLUE which contains the PKs of SOURCE and DEST as well as an integer property (order) that describes the order of DESTs with respect to SOURCE. I'd like to flatten the relationship such that I can call a method like: source.dests() - NSArray Dest where the array is ordered by source.glue.order(). I've written a simple method that grabs source.glue(), sorts it on glue.order() and then iterates to extract dest, but I'm sure this issue has been solved many, many times before in a cleaner and more elegant manner. On a separate subject thanks to all for a very interesting and informative group. I've been lurking for some time and have been enjoying the various conversations. Cheers, Charles ___ Do not post admin requests to the list. They will be ignored.
