Re: Objects don't get initialized sometimes
It seems like these errors are finally gone! Yippee!! The last thing I have done was to retire nested editing context and stay in main one.

Re: recognising dead instances
We normally implement a direct action - let's call it checkSystemStatus - that performs a fetch to ensure the database operates the way we want it. If this fetch succeeds, we just return the string OK. Otherwise we return the exception message and the stack trace. On a second system, we run a bunch of crontab controlled shell scripts (every 10 min) that perform a wget on that direct action, e.g. http://YOURSERVER/cgi-bin/WebObjects/YOURAPP.woa/YOURINSTANCE/wa/checkSystemStatus;. If that wget returns something different from OK, we send an email with the result. Very simple, but it works for us.

Updating EO by inserting new EO and archiving the old EO - any suggestions?
Hi List, I am having a dilemma on how to best implement this kind of scenario. I need the update process of an EO by creating an new EO with the updated values and archiving the old one. This EO has quiet a few to-many relationships that needs to be archived as well. I am thinking of copying the existing values along with the relationship values to an NSDictionary and tie that to the form. Once the save action fires, inspect if there are any changed values and create a new EO with the updated values and archive the old one. Can anyone suggest a better way of handling this?

Re: recognising dead instances
Hi Lachlan, Checking direct actions is a great idea. We also do a periodic netstat -n | grep CLOSE_WAIT, kill the instances which have too many connections in CLOSE_WAIT state and send alert emails with additional info (mysql process list, app's intance log tail, instance's dump, open files via lsof). Arguably, this is a bit easier to implement and maintain on a server with lots of different apps. Especially, when you cannot modify the app itself.

Re: Funky IE experiences with iFrames from different website
On 18 jan 2010, at 23:09, Johan Henselmans wrote:
I have a site that has part of its content on one website with its own
unique DNS-addres, and the Webobjects app resides in an iFrame on another
website with another DNS-address.
The first call from the website fills the frame with a directAction, then the
webObjects app in the iFrame is on its own: no funky inter-frame-inter-domain
javascript messaging whatsoever.
That works fine with Firefox, Opera, Chrome, Safari, and Chimera on different
platforms. However somebody told me of an obscure webbrowser called something
like InTheNet Exploder or what, and guess what? That thing does not work with
this setup.
I first thought that it might have something to do with cross-site scripting,
so I turned that security setting off that prevented that from working. That
did not help. The odd thing was that the moment the application in the iFrame
is continued in a new tab (just right click on a link in the app and go to
new tab), the thing worked perfectly.
On a hunch, I looked for the cookies setting in this IE thingy as I had set
the sessionid stored in cookies with setStoresIDsInCookies(true) in the
Session constructor.
You can find these thing under the Advanced Privacy Setting.
There was a checkbox to always allow session cookies.
When I turned that thing on so it always allowed for Session Cookies, it was
fixed.
After removing the setStoresIDsInCookies(true) and restoring the default
setStoresIDsInCookies(true), everything even worked in the default settings
of this Explorer thing.
Oops; meant to mention setStoresIDsInURLs(true) and
setStoresIDsInCookies(false) as the default option.
Which lead me to the following experience:
Anybody aware of any side effects of setting
setStoresIDsInURLs(true);
setStoresIDsInCookies(true);
in the session constructor?
I tried it, and it did seem to work in Internet Explorer, Firefox and Safari.
The reason is that I do not want to burden the compliant browsers with not
being able to traverse the surrounding environment of the iframe the
reservation app is framed in, and coming back to continue the reservation only
to discover that their session has gone and they have to start all over again.
So ABIE (Anything But Internet Explorer) will use the cookies sessionids, and
Internet Explorer will use the URL sessionids.
And I do not want to bother about checking for Browsers, as I would have to do
it at every Direct Action entrance into the app that would lead to a session:
if(request().headerForKey(User-Agent).contains(MSIE)){
mySess().setStoresIDsInCookies(false);
mySess().setStoresIDsInURLs(true);
log.info(NOOO: Internet Explorer);
} else {
mySess().setStoresIDsInCookies(true);
mySess().setStoresIDsInURLs(false);
log.info(Anything goes but Exploder);
}
Unless somebody knows a more elegant solution with three lines of code in one
central place that would take care of the sessionid probs with Internet Explorer
Just to make sure that nobody else has to fire up WireShark, remove all his
website code to barebones, test on different websites to discover it seems to
have something to do with cross-site scripting and waste another day that
should have been spent in blissful ignorance.

Sorting Nulls with Oracle
Hi all, Aaron Rosenzweig and I discussed the issue of how to properly implement control over how Oracle and EOF sort nulls at this month's WONoVA (http://groups.google.com/group/webobjects-nova). The only time, as far as I know, where it becomes necessary to worry about this is when you are using ERXBatchingDisplayGroup and the result set is larger than the batch size. Oracle and EOF don't agree on how to do this so you will get results that are confusing to users if there are nulls in a column being sorted on. Basically, what we've come down to is that there are 3 different behaviors that have to be handled - you should only need to figure out which one you want to use and then implement it for your application: 1) Nulls Last - Oracles default - null values will always be LAST in the result set, regardless of sort direction (asc, desc). 2) Nulls First - null values will always be FIRST in the result set, regardless of sort direction (asc, desc). 3) EOF-like - null values will be sorted as though it were the smallest possible value. First when sorted ascending, Last when sorted descending. To accomplish #1 and #2 you have to create new ComparisonSupport classes in EOF, otherwise EOF will resort the result set according to the conflicting nulls are the smallest possible value rule. To accomplish #3 Oracle's default sorting behavior needs to be modified. Luckily Oracle allows you simply to add NULLS FIRST or NULLS LAST to the end of a ORDER BY statement. For example ORDER BY NAME ASC NULLS FIRST. I have modified the EROraclePlugin to add NULLS FIRST to ascending sorts and NULLS LAST to descending sorts. Simple. Well, not so fast. There are two issues that still need addressing: 1) Oracle query results are not deterministic if you are sorting on a column with non-unique data in it. Because of this, the same DB record could show up in the DisplayGroup in multiple batches and some may never show up. The only way around this is to always sort on some guaranteed unique column, or by possibly implementing more advanced Oracle functions in the plugin. See here for more detail: http://www.oracle.com/technology/oramag/oracle/07-jan/o17asktom.html The existing code in the ERXSQLHelper.OracleSQLHelper limitExpressionForSQ() method allows for several different methods of trying to deal with this, but none are a complete solution. At this point, our business logic allows us to add a unique column to the sort so the existing code works just fine, but eventually someone is going to get bit by this, but I'm not sure what to do about it other than document the shortcoming in a comment in the source code. 2) One solution does not fit everyone (ie. Aaron and I have different business requirements for null sorting), so we need a way of specifying which sorting method an application uses. Obviously the Property seems the most logical, but since the EROraclePlugin doesn't depend upon ERExtensions, and I'm assuming it probably shouldn't, we can't use Wonder's property handling. How should this be done? Suggestions? Dave ___ Do not post admin requests to the list. They will be ignored.

Port 443 appending
Hi list, Any idea why WO is appending :443 to some URLs? They seem to appear on URLs that WO generates (URLs generated by my code seem to be fine), such as on a WO form action method. The page comes in as https://domain/wo/request/url but the generated form action method looks like https://domain:443/wo/request/url ... I've checked the archives, which indicate we need to use IP-based virtual hosting, which we already are.

How to set jvmOptions for an eclipse project?
Hi all, I'm still somewhat new to eclipse, so I need some help... How do I set the JVMOptions property that is used at launch time in a deployed application? I expect it is in the classpath file, MacOSClassPath.txt in particular. Or is this old school and it is somewhere else now? So, how do I get it set in that file without editing that file prior to deployment?

Re: ertaggable not migrating
you can see from the two connection dicts what the diff is ... AffiliateEOModel
explicitly declares a plugin name while ERTaggable does not. Just set a global
override for plugin and it should fix your problem.

Re: Port 443 appending
If you're extending ERXApp, I seem to recall that we fix this ourselves the
hard way, though I ran into this in 5.3 as well -- that you'd randomly get a
port stuck on when you didn't want it (80 or 443).
In ERXRequest:
@Override
public void _completeURLPrefix(StringBuffer stringbuffer, boolean
secure, int port) {
if (_secureDisabled) {
secure = false;
}
String serverName = _serverName();
String portStr;
if (port == 0) {
String sslPort =
String.valueOf(ERXApplication.erxApplication().sslPort());
portStr = secure ? sslPort : _serverPort();
} else {
portStr = WOShared.unsignedIntString(port);
}
if (secure) {
stringbuffer.append(https://;);
} else {
stringbuffer.append(http://;);
}
stringbuffer.append(serverName);
if(portStr != null ((secure !443.equals(portStr)) ||
(!secure !80.equals(portStr {
stringbuffer.append(':');
stringbuffer = stringbuffer.append(portStr);
}

I think I called for help too fast...
I found that my woapplication name=${build.app.name} ... segment
in the build.xml file did not have a jvmOptions key-value pair from a

It looks like I have a lot of build.xml and build.properties files to
update...
Can someone please confirm if I am correct here?

the method:
@Override
public NSArrayERXModelVersion modelDependencies() {
return new NSArrayERXModelVersion(new ERXModelVersion(ERAttachment,
1));
}
does that fix it? we should probably put that in there.

Re: ertaggable not migrating
no .. i just assumed you had an ERAttachmentMigration subclass in your app that
was adding the foreign key. if you just generated a migration from Entity
Modeler directly, then you won't need that subclass (because the foreign key
will be a part of your existing migration class). the way things are SUPPOSED
to work is that it builds a graph of relationships to figure out what the model
dependencies are. you should see on your console that it attempts to run a
migration on ERAttachment prior to your entity that depends on ERAttachment. In
your migration class, try putting that explicit model dependencies declaration
and see if that fixes it.

Re: Sorting Nulls with Oracle
Hi All, The main question Dave was asking was how to give back to the community his useful fix for a very important piece of this problem. I believe the answer is to just use NSProperties. That way the option can be given in the Properties file, from the command line, or even from your home directory. Here's the API: http://developer.apple.com/legacy/mac/library/documentation/MacOSXServer/Reference/WO54_Reference/com/webobjects/foundation/NSProperties.html All the other notes from Dave and Chuck are valuable and something you'll need to address in your own applications. Especially the Ask Tom URL that Dave gave. I'll cut and paste it again for completeness: http://www.oracle.com/technology/oramag/oracle/07-jan/o17asktom.html Also this other Ask Tom article: http://www.oracle.com/technology/oramag/oracle/06-sep/o56asktom.html One option you have is to jump start from what Mike has given you in the OracleSQLHelper then roll your own and replace it at runtime. This is also true for whatever database you use. Not only can you attempt to tweak it to get deterministic results in the general case using the oracle reserved keyword rowid you can go one step further. (BTW - rowid is like guid for the row). You can impliment an interface for specific Entities where you want to control what column to use for deterministic behavior. You can define something in the userinfo dictionary and make your generation templates latch onto that. In this way, when it comes time to do the clever batching, you can use either rowid or the special column of your entity if one is defined in Entity Modeler.

Re: ertaggable not migrating
I wanted a to-many relationship for attachments on multiple entities
(journals, payments,invoices, whatnot). In the end, I added that one
line model dependency and it work. My model defines an entity called
FileAttachment, which itself is modeled as a to-many for multiple
other entities. FileAttachment has only the to-one relationship to
ERAttachment as it seemingly requires based on what's documented. This
may add a little work in creating an extra entity before uploads can
happen, but it cleanly allows the two-many that I need.

Re: ertaggable not migrating
Another hitch. Docs say to create a convenience method:
ERTaggableEntity provides entity-level tag management and fetching
methods. Typically you would provide a cover method from your entity
class to an instance of an ERTaggableEntity: public class Person
extends _Person { ... public static ERTaggableEntity taggableEntity()
{ return new ERTaggableEntity(Person.ENTITY_NAME); } }
So.. when I define
public static ERTaggableEntity taggableEntity() {
return new ERTaggableEntity(Company.ENTITY_NAME);
}
I get an error since Company.ENTITY_NAME returns a string where as the
ERTaggableEntity expects an EOEntity in the constructor. However,
nothing else seems to work there either. Another point where I must be
doing something wrong.

Naturally when there's lots of instances running in deployment it can be hard to know if a particular instance has locked up for some reason (and this can sometimes have a flow on affect with the adaptor). We use Nagios with the check_http module (bundled with the default Nagios plugins). We check a DirectAction that simply returns OK and nothing else, but we will add two more checks : one that will fetch a very small dataset with EOF and another one by raw JDBC. By doing one check by EOF and one by JDBC, we can see if it's a EOF deadlock or not. The most important thing: don't check a page that use sessions! If you try to stop an app cleanly but Nagios or other tools keeps creating new sessions, you might have a fun time. As for checking specific instances, you can specific the instance number in the URL, but the problem is that the HTTP adaptor will send you to another instance if the checked instance is dead. BUT you can use Wonder's variant of JavaMonitor to check if a specific instance is up or not. Or, more easily, have the instance number returned in the response (e.g. 4 OK) so that the script can verify that the result is from the correct instance. Chuck Nagios is my friend! We are currently checking 211 services with it (disk space, Oracle listener port, all apps, load, ntp, etc.).
