This may, of course, not be a bug of Apple's but with the final
build. Check the executable script for your app. i.e.,
$ less YourApp.woa/YourApp
The last line of mine has this:
eval exec ${JAVA_EXECUTABLE} ${JAVA_EXECUTABLE_ARGS} -classpath
WOBootstrap.jar com.webobjects._bootstrap.WOBootstrap $
{COMMAND_LINE_ARGS} -WOFrameworksBaseURL /WebObjects/MyApp.woa/
Contents/Frameworks
i.e., the WOFrameworksBaseURL is specifically getting set (whereas
in the past this used to not be the case). Now I'm building with
maven (using the woproject-maven plugin) but it's highly possible
that seeing as it shares some functionality with woproject ant stuff
that this is also happening for you for embedded builds.
If yours also has this - then this *is* the problem. That's why your
properties are getting ignored - because the first property wins.

Hi Lachlan
This is definitely an Apple bug. It doesn't occur in WebObjects 5.3.3
but does occur in WebObjects 5.4.3. Are you deploying using
WebObjects 5.4.3 in your apps which use WOFrameworksBaseURL? If so
you need to check the urls of any static webserver resources from
frameworks because I would say they are coming from the wrong place.
Below is what I already posted to the WebObjects deploy mailing list
which shows that when you first call WOApplication.frameworksBaseURL()
it actually changes the value from whatever you have set it, to /
WebObjects/Frameworks. This is particularly dangerous in a deploy
situation because you think it is using the latest ajax scripts from
your embedded frameworks in your split install, but in fact it is
using some old ajax javascript that happened to be sitting /Library/
WebServer/Documents/WebObjects/Frameworks.
To identify the bug I added some more logging and overrode some
WOApplication methods. As you can see the first call to
frameworksBaseURL() in WebObjects 5.4.3 actually calls
setFrameworksBaseURL(/WebObjects/Frameworks). This does not happen
in WebObjects 5.3.3
public class Application extends WOApplication {
public static void main(String[] argv) {
WOApplication.main(argv, Application.class);
}
public Application() {
NSLog.out.appendln(Welcome to + name() + !);
/* ** put your initialization code in here ** */
if ( System.getProperty(WOFrameworksBaseURL) != null )
setFrameworksBaseURL(System.getProperty(WOFrameworksBaseURL));
frameworksBaseURL();
if ( System.getProperty(WOFrameworksBaseURL) != null )
setFrameworksBaseURL(System.getProperty(WOFrameworksBaseURL));
frameworksBaseURL();
}

Re: Bug ID 6342679: NSTimestamp Happy New Year Bug
Bardi,
OK - it took me all of 10 minutes to solve this.
1. You choose Atlantic/Reykjavik, not GMT, like we suggested.
2. In 1969, Iceland stopped respecting Daylight Savings Time:
http://www.timeanddate.com/worldclock/timezone.html?n=211syear=1960
date in yearFromDate : 1968-01-01 00:00:00 Etc/GMT
yearFromDate : 1967
TimeZone:Atlantic/Reykjavik
date in yearFromDate : 1969-01-01 00:00:00 Etc/GMT
yearFromDate : 1969
If you had chosen GMT, where there's no shifts for daylight savings
time, it's always accurate.

Bardi,
I think the most important thing to understand about how dates are
moved around is that the value is always GMT based. Timezones are
there for convenience...
For instance, when you create a new timestamp with a timezone, the
timezone is used to adjust the date/time you sent in to GMT and the
GMT value is stored. When formatting a date or extracting day/month/
year from GregorianCalendar, the timezone is used WHEN FORMATTING THE
RESULT.
If you work with these tenets, things will hopefully be easier.

This will make sure that you're really working in GMT across the
board. Can you do the above and try your tests again?
Yep.
Behaves correctly - no way
Yes way :-)
NSTimestamp reports a timezone which is not used by
GregorianCalendar ??
GregorianCalendar does *not* change its timezone based on the date
passed to it. You are responsible for determining that. That's
nothing to do with NSTimestamp.
This is a difficult bug.
Just more a misunderstanding on your part.

Re: OpenBase WebObjects for scaling
Andrew, Another thing that's impressed me with OpenBase is the clustering failover. I doubt many people have used this feature. Any SQL written to any database in the cluster is automatically propagated to other OpenBase databases in that cluster within five seconds without any primary key collisions. Additionally, if the master database fails your WebObjects app will automatically begin using another database in the cluster (no code needed to handle this case). Once the master database recovers, its SQL, from the other databases, is updated and it resumes handling the WO app's SQL.

I was seeing this for 5.3.3 - not because of WO but because of the

the app script.
Below is what I already posted to the WebObjects deploy mailing list
I saw that yes.
which shows that when you first call

Sure. I'm just suggesting to double check the end of the app script
i.e.,
$ tail YourApp.woa/YourApp
and check if it's adding the frameworkbase url arg. If not then
everything you've said still holds.

That seems a little odd. That class is pretty old, so this might be
from long ago.
After setting the encoding with setDefaultEncodingForAllLanguages to
UTF-8, I got it running. Dont know if this is some kind of a bug,
the encoding should be set to the request encoding and this is/was

I have also noticed, that this is a general problem... not only

Do I have a miss understanding here?
You _might_ be missing something from your Properties file. I don't
do much with this part of Wonder. I can't think of a good reason to
have a web app that is not UTF-8. You might want to ask this on the

I also did this for my WO framework that contains the jars I need to link in to, using a new dummy framework. Now I get sight of my problem a step earlier, when trying to install (WOLips Ant Tools, Install), where I see: /Users/john/EclipseWork/workspace/MPMall/Sources/mpMall/ SyndicationFeedBuilder.java:15: package com.sun.syndication.feed.synd does not exist [wocompile] import com.sun.syndication.feed.synd.*; ...[snip] Though there are still no errors showing in my actual code, this only shows up when I try to install. If this package can't be found, why doesn't it show in my source file? When I look at the Java Build Path of my application after upgrading to hotness, I see that things that were previously listed as dependent Projects in the Projects tab I confess that I have little idea what the contents of that tab do or are for. Mostly, I have nothing there. are now shown in the Libraries tab as things like MPServerEOs Framework. So what is now the suggested way of adding dependent frameworks? Go to the Libraries tab, click Add Library, select WebObjects Frameworks, select your framework. You probably need to install it before doing this, I forget. I can still do so in the Projects tab, but can't see how to confirm with what is now showing in the Libraries tab; I can't see how to add my framework that contains the jars and have it appear like the others now do as MyJarFramework Framework. Perhaps if I can solve this it will remove my compile problem as the framework in question contains the jar that contains the missing com.sun.syndication.feed.synd package in the error message. I believe that it will fix your problems. Chuck On 8 Jan 2009, at 14:01, John Pollard wrote: Lachlan, Many thanks for your reply.

No, the two ec's in your example will properly update (you're not holding an ec lock across requests, so the first EC is causing the second EC to update). The easiest way to force an optimistic lock is to go into your edit form on an EO, and then update the database manually with SQL commands in the background. This will cause your snapshot cache to be out of sync. The only way to get it to happen INSIDE your app would be to have two EC's attempt to change the value while both are locked. Or to have each EC created using a different EOF stack. EOF won't sync across stacks within the same instance (though doubtless Wonder has something to provide this if desired).

onChange is static JavaScript, it does not make a trip to the server.
onChangeServer sends the current slider position/value back to the
server and has the application dynamically generate the JavaScript to
return to and execute on the client.
In the SliderExample from the Wonder project, they use OnChange and
OnSlide for the client javascript, like this:
AjaxSlider1: AjaxSlider {
orientation = horizontal;
value = 10;
minimum = 0;
maximum = 10;
