Re: Flattened relationship and iterator oddness
I stumbbled on this one too. Did someone file a bug report ?

Fabian,
I discovered this a month or two ago. It appears as if iterator()
does not fire the fault on relationships. That is why with your log
statement everything is ok: the accessing of the productionRuns()
field IS firing the fault. The iterator then works. This is a bug
in the iterator implementation. The only thing you can do is either
manually fire each fault or use objectEnumerator(). I use
objectEnumerator().

Hi,
I've got the following entities:
Order <->> OrderItem <<->> ProductionRun <-> DeliveryDefect
In Order, I've defined a flattened relationship deliveryDefects. It
works fine for deliveryDefects that exist when the order is fetched
from the DB. However, it fails to include a deliveryDefect that is
created and then saved to the DB. Is this a known limitation of
flattened relationships?
Not all too important since I can of course get to it myself. Part
of my first implementation looked like this:
for (Iterator iter = orderItems().iterator(); iter.hasNext
();) {
OrderItem anOrderItem = (OrderItem) iter.next();
// log.debug("production run count: " +
anOrderItem.productionRuns().count());
for (Iterator iterator = anOrderItem.productionRuns
().iterator(); iterator
.hasNext();) {
ProductionRun aProductionRun = (ProductionRun)
iterator.next();
if (aProductionRun.deliveryDefect() != null)
deliveryDefects.addObject
(aProductionRun.deliveryDefect());
}
}
Now, I'm using WO 5.3 with java 1.5.0, so I assumed this should
work. But it fails due to iterator.hasNext() always returning
false. While debugging, I introduced the log statement that is
commented out above. With that in place, the iterator starts to
behave correctly!?
I'd really like to understand what's going on here! Is the
productionRuns() fault not getting fired by the iterator? Is this
intended/documented?
Now I'm back to using good old Enumeration which works w/o further
ado.
Any comments most welcome...
Fabian

There is not one header that consistently gives you the correct information on an incoming request; besides which virtual hosting makes it impossible to ascertain the correct info from an ip address.

Re: Mysterious field not reachable from entity error
it looks like there's some code you didn't show us. Are you using this qualifier in a fetch specification somewhere? Arg, yes. I found my problem. I was attempting to fetch rather than filter based on the result of a method. Now I create an array of all the objects and then filter them. Works fine. Anyway, I'm now familiar with the difference between the two tools. Many thanks to all that helped. --matt ___ Do not post admin requests to the list. They will be ignored.

We use DB2 for one of our WebObjects projects. We were just using the normal JDBC stuff until we encountered a problem with LEFT OUTER JOIN syntax and needed some additional non-JDBC DB2-only functionality, so we ended up writing a small plugin to work around those. I don't think I can publish the class, but I can give snippets. It was my first attempt and probably not very good, but it worked for our needs. We've not had luck with the pure-Java drivers, but that could easily be a function of the strict nature of the DB2 database we access. The native type-2 drivers work just fine, though they were a pain to install and get working. Logan ___ Do not post admin requests to the list. They will be ignored.

Re: Obtain the name of a server in WO
Gilles,
there is a non documented ( not yet public but perhaps in the future if
Apple Open-souce WO :-) ) API on the WORequest : public String
_serverName()
WebObjects use it internally for the isSecure bindings on the
WOHyperlink
HTH,

Hello list,
After a few search in the WO documentations and experimentation, and
owe to the people who send me clue and their way of doing, i think i
found a way to have the server name, yet i hope so.
I used the WOContext request() method. As u surely know (in fact i
write this for the other newbie like me :-)) (WOContext context) is an
argument of the constructor of ur WOComponent. So i wrote a few more
line in it, to get what i want.
=== Example ===
At first u have this :
public MoviePage(WOContext context) {
super(context);
}
==
I added this :
public MoviePage(WOContext context) {
super(context);
WORequest request = context.request();
String serverName = request.headerForKey("host");
System.out.println("Server Name is :"+serverName); // For
verification
}
==
after going to the MoviePage when i check the console i obtain this :
Server Name is : g-five.local.
That's what i should obtain. Then when i use the ivar serverName in a
method who built a static URL like :
String dynamicVideoUrl = "http://"+serverName+"/folder/movie.mov";
the movie is displayed. Now i only hope that the server name is really
the "apache domain name" (the static one). As the http server and the
application server are on the same machine, it seems impossible to
figure it out.
Maybe the more experienced WODeveloper could tell us ?
Regards.
GM.
