Re: Where is the best dir to put my jdbc.jar?
Nothing should go into the Extension folder. Maybe today all of your apps are for DBxy 4.0. If you put the driver under Extensions you have to move all your apps to 5.0 at once. Even if your intension is to upgrade only one of your apps to DBxy 5.0. Never ever put anything under /Extension or /ext. One exception is the eomodeler which requires your driver under / Extension.

Re: Where is the best dir to put my jdbc.jar?
Actually, driver makers should try to maintain backward compatibility, so that is probably not THAT much of a problem (with postgres it wasn't at least). But still you're right.

[Announce] Invite to try out our new Web2.0/WebObjects powered site
I'd like to share the relaunch of our WebObjects/Wonder/WOLips website 'Treasuremytext' plus an invitation to try out the closed beta with the WO Community. I figured this was the best place but apologies first if anyone finds it a bit off topic. A quick background to this. Treasuremytext is a simple SMS text message storage service. This new version is an attempt to bring it bang up to date using all the recent developments in WebObjects. During its redevelopment WOLips, Wonder, the lists and Wiki resources have all played a big role and proven invaluable. A huge amount of thanks to everyone here and in the community for keeping WebObjects alive and kicking and providing so many great resources and tools. Our main objective with this relaunch was to enhance the site using using modern web development techniques. Ajax, drag n drop, betas, invites, colourful gradients reflections are all features of the site bringing it into a modern Web 2.0 era. We're really happy with the results and we hope this is a great showcase and example of the use of WebObjects. Currently the site is only open to invites (of course, being a web2 thing) but we've added an open invite for WebObjects people. To use it you need to do this: 1. Visit http://beta.treasuremytext.com 2. Click on 'Create Account'. 3. You'll be told to ask for an invite by email, here just use the email address '[EMAIL PROTECTED]' to get straight in through the back door. Two caveats for its use. We are currently operating on a Dutch mobile GSM number so if your in the US it will only work with ATT and T- Mobile. The second if your on an iPhone you'll have to look around for a thing called SMSD for forwarding messages, this is a stopgap until the iPhone SDK becomes available after which we plan to do something much more integrated. Regards the SMS integration if anyone else needs such a thing, I've implemented this in a framework using the Logica OpenSMPP Java library. I'd be happy to share after cleaning it up if anyone has any use for such a thing. It's only useful if you have an SMPP Gateway provider to integrate with but these are simple to get. You can do lots of fun stuff with SMS! Paul Stringer ___ Do not post admin requests to the list. They will be ignored.

Much thanks for trying, it was a ray of hope, and I have been working with it and reply as follows... If I make the 10.5 box the DNS server, by switching the Ethernet cables, the wotaskd error goes away, I guess I understand that. I don't. I've done some more testing and indeed there is always an erring apple.com.womonitor process, i.e. wotaskd? Now if I make the 10.5 box a real DNS server by switching Ethernet cables webobjects.log shows a running non-erring wotaskd, but system.log shows a continually crashing apple.com.womonitor. Now I see in Activity's Process pane 2 Java processes, started by launchd and a third Java process which comes and crashes (with below) every 6 seconds. How many Java processes ought there to be after a successful boot? cascadewebdesign com.webobjects.wotaskd main Unable to establish a connection to port 1085 on this host. Perhaps this port is already in use by another WebObjects application instance. BUT, those messages did not appear in webobjects.log, whereas they had before switching cables? So this womonitor problem seems to me to be preeminent to the password error. That must be the canonical name of that machine. It is a new machine, where is the canonical name set? I don't see the field host in com.apple.womonitor.plist so I don't know where the host name cascadewebdesign.com (which is me) is coming from in the above? Reverse DNS lookup of the IP address? Ah. I'm trying to set up a 10.5 server running DNS services via Apache and FrontBase (I finally got the DNS services up, last problem was that Server Admin had written site files with port 16080 specified rather than port 80 as I require, some virtual host specification caused the error, no doubt). No, that was webperfcache. Well, this is a virgin 10.5 so according to http://developer.apple.com/documentation/Darwin/Reference/ManPages/ man8/webperfcache.8.html webperfcache should not have been a player. But it was because I used the old site files, from 10.4 box, ah again. Goal: The old 10.4 server will continue to run WebObjects 5.3 and all the five deployed WOApplications, it is currently running wotaskd and JavaMonitor, FrontBase, and Apache all together. I have no idea if you can mix WO 5.3 and 5.4 deployment. Well, I'm not mixing them on the same computer. For now I am planning on just using the 5.3 deployment for WO apps. I need to bring up the new server with 10.5 as my 10.4 server software won't install on the Intel box. I really would like to do this as a multi-computer deploy, one of my non-profit organizations that I have a WO app running for gave me the computer and the required new server software. Then I will convert the 5.3 apps as needed, so at that point I would need to have a mixed environment, but still on separate computers. On 10.5: /System/Library/WebObjects/Adaptors/Apache2.2/apache.conf and the line WebObjectsConfig http://localhost:1085 10 So I changed the line in apache.conf on 10.5 box to: WebObjectsConfig http://216.vvv.xxx.yy7:1085,http:// 216.vvv.xxx.yy8:1085 10 In both cases if I try to add the 10.4 box as a Host from the JavaMonitor page on the 10.5 box, I get: (ISP Name): Invalid Password - Access Denied Check /System/Library/WebObjects/Adaptors/Apache2.2/apache.conf for the password config. I don't see how that is done in apache.conf, there's some lines about the WOAdaptorInfo, but that does not reference out to the computer which is trying to be added as a host? I wonder if in the Host line I should do something like ( but then you couldn't add the Host via JavaMonitor's GUI ): WebObjectsConfig http://216.vvv.xxx.yy7:1085,http:// 216.vvv.xxx.yy8:1085?user+password 10 Is this message Invalid Password - Access Denied referring to JavaMonitor's password on the remote host, or the SSH login? Maybe I should try Multicast Configuration, but I don't understand it anyway, they use the line: # WebObjectsConfig webobjects://239.128.14.2:1085 10 for multi-casting, is that a magic IP that everyone uses, or just a placeholder?

Re: Change Notification vs New EditingContext vs ?
I am not sure what the ERJGroupsSync code buys me over JMS (I will take a
look though). I don¹t think our biggest problem is getting the notification.
I think our biggest issue is dealing with freshening up our data once we get
the notification. It seems that since our app is pretty busy the act of
invalidating the objects seems to cause other sessions to lock up. Is that
because we are not locking the ObjectStoreCoordinator?

I'm totally biased here, but I agree with Simon -- You should definitely check
out ERJGroupsSync ... This is an incredibly hard problem to get right, and I
was only ever able to do it properly when I ultimately hooked into
EODatabaseContext directly to be able to get cache change notifications. In
almost any other way (I went through about 3 or 4 implementations before
settling on the current one), you are bound to end up with dead locks, lost
updates (like not receiving updates of the inverse relationship being
updated), or really expensive change tracking. That you have that lock
commented out gives me a HUGE case of the willies. I spent several weeks of
development on this problem .. I would say it's the most complicated work that
I've done on WO, in fact, mainly because things are so fragile at this level.
One slip of a lock or a misunderstanding of calling order, and horrible things
happen. I won't claim that ERJG is without bugs, but I can assure you this
code sample you're showing is really scary :)

The big problem we are facing on the change notification is the object
invalidation within EOF. JMS seems capable of getting the messages where they
need to be, its just we are getting NSRecursiveLocks when trying to
invalidate the individual objects. We do something like the following (we
only send the globalids in the JMS message):
public void run() {
NSMutableSet ids = IMGlobalIDsQueue.getIdsAndResetQueue();
int count = 0;
if (ids != null ids.count() 0) {
EOObjectStoreCoordinator coordinator =
EOObjectStoreCoordinator.defaultCoordinator();
//coordinator.lock();
count = ids.count();
try {
coordinator.invalidateObjectsWithGlobalIDs(ids.allObjects());
} finally {
//coordinator.unlock();
}
}
}
We build up a queue of the incoming messages and process them with a timer
thread with the above code. If we uncomment the coordinator.lock()/unlock()
methods bad things happen very quickly. The timer is a singleton class so
there should only be a single timer per application/object store coordinator.
It seems the lock is happening when a new EditingContext is being created by
either a session or via new EOEditingContext().

We have been throwing around various strategies but I wanted to vet them

Application Profile:
Our application is deployed as a servlet using a WAR file that gets
expanded by the container (Tomcat 5.5). The app is currently built using WO
5.3 but we are in the process of converting it to WO 5.4. Our application
is typically deployed in multiple tomcat instances across 1 or more
machines in a network. We have an administration console, a web client
(using EOF based custom JSP tag libs that we created), and a set of EOF
based Apache Axis web services. The web client is primarily read only and
makes extensive use of the SharedEditingContext. The web services client is
basically stateless. The mgmt console is a typical WO/EOF application that
uses the defaultEditingContext extensively. We have borrowed some Project
Wonder components and adapted them to our needs but have not implemented
the whole Project Wonder set of frameworks. Administration console users
generate content that the web client and web services clients interact
with.

Tiger? Leopard? WO 5.3? 5.4? Have you checked the Console log?

Could not find EOClassDescription for entity name... (newbie)
Hello all, I'm trying to follow Janine's WebObjects Tutorial (http://wotutorial.furfly.com/downloads.html ) I've created my model just fine, generated the code, and created an AddEdit component. In the AddEdit code, I have the following line: displayBoard = (DisplayBoard )EOUtilities .createAndInsertInstance(session().defaultEditingContext(), DisplayBoard); Where DisplayBoard is the model I've generated. When I try to run the project though, I get this: Application: nhlpm Error: java.lang.IllegalArgumentException exception Reason: java.lang.IllegalArgumentException: Could not find EOClassDescription for entity name 'DisplayBoard' ! I'm sure I just missed something but I can't seem to find it. The DisplayBoard class references the same string, and I'm not sure if it needs to be registered somewhere, or whats going on. Any ideas? (Note: using WOLips + WebObjects 5.4) Thanks!! ___ Do not post admin requests to the list. They will be ignored.
