WO Context() null in Session Constructor

[Joe Moreno]

Hi all,

I'm probably not remembering my WO request/response loop correctly.

When a WO Session is created I'd like to find out the host name of the 
request so I tried to log that info in the Session's constructor (see code 
snippet below). Unfortunately, the context() is null at this point.

Where's the best place to figure out the remote host that created a 
session if not in the session's constructor?

Thanks,
Joe


public Session()
{
super();
NSLog.debug.appendln("== Session Created ==");
this.setStoresIDsInCookies(true);
this.setStoresIDsInURLs(false);
this.setDefaultEditingContext( ERXEC.newEditingContext() );
String remoteHostName = 
this.context().request().headerForKey("remote_host");
NSLog.debug.appendln("Remote host name = " + remoteHostName);
}

CSV File Reader

[Joe Moreno]

Can anyone recommend a simple CSV file reader for WO?

It needs to be smart enough to escape commas inside quotes, i.e.:
Name, Location
John Smith, "Cupertino, CA"

I'm sure that this wouldn't be hard to write, but code I don't have to  
write is code that I don't have to debug. :^D


Many thanks,
Joe

I think wonder would have provided something to avoid cyclic fetch.

Re: OT: JPEG EXIF Image Orientation

[Joe Moreno]

Matt,

	BINGO! exiftool has a wealth of info; specifically it has the  
Orientation tag which is what I was looking for (not to mention access  
to all of the photo's GPS data too).


I don't know how I could have overlooked that before.

	We have WebObjects running on Mac OS X Server 10.4.11, which doesn't  
have the exiftool command, natively, but we fixed that by simply  
loading the stand along exiftool from here:

Re: WO MacOS[Server]ClassPath.txt settings?

 I think the "streamToFilePath" binding is what you need to use.   
What bindings are you using?


I'm not using a WODynamicElement (i.e. WOFileUpload). This is a direct

Does anyone have a recommendation on how to manage a file

takes longer than the WO adaptor time out? Or, should I just  
set the WO adaptor timeout to something like five or ten  
minutes to handle slow/flaky EDGE connections?

You could try my "solution" - I see the exception in the logs and,

I can imagine stuff like that happening, when you do things in a

thread - with an attached editing context that is autolocking.


Not sure, whether this can still come from situations like that,

SQL doesn't seem to match complex qualifiers

[Joe Moreno]

Hi all,

	It seems my graphical fetch spec is looking different when turned  
into SQL.


I'm using the following graphical fetch spec:
(includeExcludeType = "0")
or
((includeExcludeType = "1" and ((not (excludeList like $lastName)) or  
(not (excludeList like $firstName) or
((includeExcludeType = "2" and (includeList like $lastName or  
includeList like $firstName)))



But, for some reason, the order of importance (i.e. parenthesis) in  
the SQL seems to be getting messed up. Here's what I'm seeing being  
sent to the database:


(
t0.INCLUDE_EXCLUDE_TYPE = ? OR
(
t0.INCLUDE_EXCLUDE_TYPE = ? AND
(
not
(
t0.EXCLUDE_LIST like ?
)
OR not
(
t0.EXCLUDE_LIST like ?
)
OR
(
t0.INCLUDE_EXCLUDE_TYPE = ? AND
(
t0.INCLUDE_LIST like ? OR 
t0.INCLUDE_LIST like ?
)
)
)
)
)



	I'm not sure what I'm doing wrong. The last OR should not be  
"indented".


Thanks,
Joe

Re: OpenBase & WebObjects for scaling

[Joe Moreno]

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.


Ciao,
Joe

Re: EO Not deleting

[Joe Moreno]

I've made this mistake before and I keep forgetting...

I forgot to remove the EO from it's relationship before deleting it.  
Once I did that, the EOs were deleted as expected.


I'm not sure why EOF would sometimes delete the EO and sometimes it  
didn't - but, unhooking it before the delete solved the problem is all  
cases.

OpenBase & WebObjects for scaling

[Joe Moreno]

Hi all,

Does anyone have any real world, recent, experience with OpenBase on a  
large scale?


I've been using OpenBase for more than 10 years. During that time,  
I've also used Oracle, Sybase, FrontBase, and MySQL, to name a few.


I've been extremely impressed with OpenBase's support of WebObjects -  
more so than any other database that I know of.
Additionally, OpenBase supports bidirectional clustering with up to  
100 computers and the latest release supports incremental backups.  
These certainly seem like high end features to me.


Most recently, I've been using OpenBase to run in parallel with  
Amazon's SimpleDB. So far, both have written millions of rows of data  
to both database systems without any issues. But, SimpleDB is not a  
RDBMS; also SimpleDB has some other limitations.


Your experiences are greatly appreciated.

Cheers,
Joe

Long response web service

[Joe Moreno]

	What's a good way to handle a WO request, from a third party API call  
(web service), that generates a long response?


	For example, a web service call comes into a WO app whose response  
takes 60 seconds (i.e. a large database fetch and data aggregation).  
Normally, a WO long response page could handle this in the web  
browser, but, this doesn't really work with a web service and if the  
response time is longer than the WO adaptor timeout the request will  
fail.


Thanks,
Joe

Amazon's SimpleDB & WO

[Joe Moreno]

Hi all,For anyone interested in experimenting with Amazon's SimpleDB and EOF...I've attached a very simple Java thread I've been using to copy EOs from RDBMS database tables into SimpleDB. Eventually, an ideal solution would be an EOF adaptor for SimpleDB. The attached code, which I manually edited for this e-mail to remove some dependencies (so it might not compile), relies on my own Timer class and Typica which can be found in Google Code:http://code.google.com/p/typica/I have been testing out Amazon's SimpleDB as an off site backup for local database rows that don't change (i.e. history events). This week, Amazon made SimpleDB tinkering even more appealing when they lowered the price to:1. Free for the first 25 machine hours2. Free for the first GB of transfer in and out3. Free for the first GB of storage.Prior to this month, my bills for SimpleDB have been less than $3/month for more than 1 million monthly database transactions.If you're not familiar with SimpleDB then the simplest analogy between SimpleDB, which is not a RDMS, and a RDBMS is:RDBMS		SimpleDBTable		DomainRow		ItemColumn		AttributeThey key difference between SimpleDB and a RDBMS is that SimpleDB does not have an ER model. Details about SimpleDB can be found here:http://aws.amazon.com/simpledbIn PracticeIn my environment, it takes about a 400 ms to write an Item to SimpleDB with a dozen Attributes. Your time will vary depending on your upstream bandwidth. Since this network latency is a significant amount of time for a single database transaction, the attached Java class was designed to run in its own thread.The following code snippet copies all of a table's columns to SimpleDB:EOEnterpriseObject transaction;CopyEOAttributesToSimpleDBThread copyEOToSimpleDBThread = new CopyEOAttributesToSimpleDBThread(transaction, false);copyHitToSimpleDBThread.start(); Your feedback is welcomed,Joe

Re: WO in the cloud (again)

[Joe Moreno]

Anjo,

No, I haven't looked at CouchDB until now (on Wikipedia).

The limits you mentioned on SimpleDB are interesting:
http://ad.vu/9vg

	If I'm reading the 250M attribute name-value pair limit correctly,  
that means a domain (table) with 10 attributes (columns) could only  
hold 25M rows of data provided the total for the domain was less than  
10 GB.


	While this sounds small, I'm speculating that if a SimpleDB customer  
was close to that limit Amazon could increase the limit on a case-by- 
case basis.


Cheers,
Joe

- would it make sense to create an EC2Monitor app that would take  
care of starting/stopping on demand. This app would use the ec2 API  
for this (probably some sort of enhanced JavaMonitor)
- anyone tried to simply use these things for strictly app-serving?  
I.E. run the DB and web servers at your machines, run the apps on EC2?
- ever used anything that is not a RDMS? Like SimpleDB or CouchDB?  
One would think that the REST adaptor in Wonder might help here
- is this cost-efficient? I.E. isn't the overhead of managing the  
cloud vs the cost of a few machines that you manage too high? And  
you get 2Gig for a small instance for ~70$/month... which is about  
what I get with my hosting provider. Of course, I can't start and  
stop or reimage as easily there... so is the whole thing worth it?


Cheers, Anjo

For some reason, the URL (boldfaced, below) key/value is incomplete  
- it appears that WO is trying to parse out the contents of the URL  
value. (There's only one form value in the JavaScript call but WO

Here's are the form values, headers, and URL from the WO app's  
context object:

Re: JavaWOExtensions Red Dots

[Joe Moreno]

Lachlan,

Thanks. So, I have a follow up question...

	Since there are two JavaWOExtensions when configuring the Eclipse  
build path, one under Local and one under System, should I uncheck the  
one under System (WO framework) and only check the on under Local  
(WOnder framework)? Or, do I need both?


Thanks,
Joe

Seriously, all the standard frameworks that you would usually link  
to your project have this symbolism. If you're using WOnder then  
you'll want the WOnder version with the same name.

Re: Unable to release locks held by deallocated EOEditingContext

[Joe Moreno]

Mike & cug,

	What are the gotchas when setting it to automatically lock &  
unlock? Performance? It seems to be working like a charm.
I need to add this to the same Properties file ... Ditch all those  
individual locking settings and just set:


er.extensions.ERXEC.safeLocking=true


	Thanks for pointing that out – it's working fine when I launch my  
apps in Eclipse (3.3.2 w/ WOLips 3.3.5047). But, it fails to launch  
when it's deployed on Tiger Server. I'm only looking to use ERXEC.


I followed these instructions:
http://wiki.objectstyle.org/confluence/display/WONDER/Integrate+Wonder+Into+an+Existing+Application

I've pasted a couple logs, below.

	It seems to have a problem when I put the three Wonder jars (ERJars,  
ERExtensions and JavaWOExtensions) in the project or in /Library/Java/ 
Extensions. I also tried using the Wonder frameworks without any luck.


	It seems, with the jars present, that it can't find some basic WO  
classes.


Both dev and deploy are WO 5.3.x.

Any tips would be greatly appreciated.

- Joe

There are some tutorials on the Objectstyle wiki. Haven't really

- Inherit from ERXApplication (there are two occurrences in the  
Application file!)


- Inherit from ERXSession & ERXDirectAction

- Read the properties and set values for the ones that seem useful  
to me.


- Use ERXEC.newEditingContext() whenever I need a new editing context.

That's it.

Re: Unable to release locks held by deallocated EOEditingContext

[Joe Moreno]

cug,

	I dropped in the er.extensions.eof package for WO 5.3.x to test it  
out in place of a peer EC I'm using inside a session based WO component.


	I only installed what I thought would be the minimum to get ERXEC to  
work - specifically, I added the ERExtensions-5.0.0.8093.jar to my  
project.


Is this the correct way to create a peer EC?
EOEditingContext _editingContext = ERXEC.newEditingContext();

I'm getting a bunch of warning stack traces, pasted below.

Thanks,
Joe

for unbalanced lock()/unlock() pairs.


	If you're attempting to manage EOEditingContext locking

Unable to release locks held by deallocated EOEditingContext

[Joe Moreno]

WebObjects 5.3.3 on:

ProductName:Mac OS X Server
ProductVersion: 10.4.11
BuildVersion:   8S2169

Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13- 
b05-241)

Java HotSpot(TM) Server VM (build 1.5.0_13-121, mixed mode)



In the WO app instance logs I'm getting seemingly random "Unable to  
release locks held by deallocated EOEditingContext." exceptions.


I'm not quite sure what is causing these exceptions which I cannot  
consistently reproduce.


The following is a sample app instance logs with both  
EOAdaptorDebugEnabled & WODebuggingEnabled set to true right after the  
app instance was launched.

I'm not sure where to begin looking for the cause of this exception.

Re: Backtracking and Safari

[Joe Moreno]

Chuck,

	When I start wondering if Safari is caching a page or if it's my own  
bug I add something useless to the end of the URL (i.e. either server  
side or client side via JavaScript). Usually, I'll just tag on a key/ 
value pair such as ?t=1212726377311 which is simply the time. To  
Safari, and any proxy servers, this appears as a new request.

Hi,

Safari, at least as of version 3.1.1 (5525.20) does not seem to  
respect the headers that control local page caching.  The Safari FAQ  
claims to show how to do this:

http://developer.apple.com/internet/safari/faq.html#anchor5

Returning
last-modified = ("Wed, 04-Jun-2008 00:10:53 GMT");
cache-control = ("no-store, no-cache, must-revalidate, max-age=0,  
post-check=0, pre-check=0");

expires = ("Mon, 26 Jul 1997 05:00:00 GMT");
date = ("Wed, 04-Jun-2008 00:10:53 GMT");
pragma = ("no-cache");

still results in Safari using the local cache instead of making a  
trip back to the server.  The Web Inspector in Safari show that it  
is getting these headers, but it seems to ignore them. I have  
reported this to Apple.


Obviously, this has rather serious implications for those of use  
deploying dynamic web applications.  The back button is hard enough  
to deal with when the browser works correctly!


Any suggestions for work arounds gratefully attempted.

Chuck

WO 5.3.x & workaround?

[Joe Moreno]

Hi all,

	Does anyone have a generic workaround for WO 5.3.x to prevent  
ampersands from getting escaped on R/R loop  direct actionURLs?


	I have a page which is sometimes returned as a session-less based  
direct action and sometimes it's returned as a session based direct  
action with a wosid on the URL.


In the latter case, the URL looks like this:
MyWOApp.woa/wa/loginPage? 
wosid=V7HO3tAja0qE0HYoDyxZiw&errorMessage=Invalid+login+or+password


	Obviously, I'd like to change the & to just &. My current  
workaround is:
String errorMessage1 = (String)  
this.context().request().formValueForKey("errorMessage");
String errorMessage2 = (String)  
this.context().request().formValueForKey("amp;errorMessage");


Thanks,
Joe ___

Re: Local Instance of EO Problem

	Upon closer examination, I am seeing that if an EO field was null,  
then updated, but not saved, it seems that the unsaved, previously  
null value, gets pushed into the snapshot 'cause I see the new,  
unsaved value, appear when getting a local instance from a peer EC.


Peer or nested?  You will see the unsaved value if doing  
localInstance on a child EC.




Does that make sense, or, am I'm overlooking a bug in my code?


It does not make sense for a peer EC.

In the process of moving an EO from one EC to another it seems

Am I overlooking something obvious, here?

The following code:

Re: Local Instance of EO Problem

[Joe Moreno]

Chuck,

	Upon closer examination, I am seeing that if an EO field was null,  
then updated, but not saved, it seems that the unsaved, previously  
null value, gets pushed into the snapshot 'cause I see the new,  
unsaved value, appear when getting a local instance from a peer EC.


Does that make sense, or, am I'm overlooking a bug in my code?

Thanks,
Joe

.classpath ignored?

[Joe Moreno]

WO 10.5.2, most recent Eclipse with stable WOLips. Running WO 5.3.3

I renamed a WO project in Eclipse in three steps:
1. File –> Rename
2. Changed the project name in build.xml
3. Changed the project name in build.properties

All seems well except when I build and run inside Eclipse.

	Building from the command line, using ant, works too, but the class  
path in the dist is incomplete.
	Even though my .classpath is correct, the resulting  
MacOSXServerClassPath.txt and MacOSXClassPath.txt do not have all of  
the dependent frameworks.


	If I manually add the frameworks to those two txt files, the app  
deploys fine.


What am I missing?

Ant class path deployment issue

[Joe Moreno]

Hi,

	I had a problem deploying a WO app, built with ant. EOs, in another  
framework, couldn't be found at runtime due to a NoClassDefFoundError.  
But, all was well when running in Eclipse.


	After digging around for a while I noticed that the a framework class  
path was missing on in the WOA under dist on the deployment machine. I  
added it manually and all was well.


	I don't understand the details of the relationship between ant and  
Eclipse/WOLips, but, once I changed the WO app's Java Build Path's  
Order and Export, by moving the EO framework to the top of the list,  
all was well with my ant builds.


	Can someone explain the significance of the Eclipse's Java Build  
Path's Order and Export and it's relationship with ant's build.xml (if  
any)?


Thanks,
Joe

Re: EOGenerator Almost Working

[Joe Moreno]

Guido,

	Thanks for your tips. I know that putting the EOs in the default  
package is dirty, but I'm trying to simplify the problem. I've tried  
putting the EOs in a package and in the default package with the same  
problems.



Which version of WOLips are you using?


3.3.4574

Here's the strange part – I've removed all references to the template  
files in my project and Eclipse but WOLips is still picking up the  
template files from somewhere.
I then edited the template files and I don't see the edits in my  
generated EOs. Very odd.


I would have thought that the following eogen file would have failed,  
but WOLips is picking up the template files from somewhere:
 -destination src -model MyEOModel.eomodeld -subclassDestination src - 
verbose -define-EOGenericRecord EOGenericRecord

Interesting enough - I didn't have to do that.


So, I'm very close. But, I still get this as my first line:

Perhaps I'm not setting the package or variable correctly?

Re: EOGenerator Almost Working

[Joe Moreno]

Hi Pierre,

Thanks for your help.

1- I would really suggest that you place you code in a package, this  
is very strongly recommended by the Java language.


No problem. I did that and it still shows up in my generated EOs:
package ${entity.packageName};

Here's the strange part, I've edited the _Entity.java and removed the  
following line but the package still shows up.

package ${entity.packageName};
I can't figure out where EOGenerator is picking up its template files.

2- I have fond that problem too in the default templates open you  
eogen file and at the bottom define a variable EOGenericRecord with  
value EOGenericRecord. This looks silly but it is done so that you  
can have you own sub class of EOGenericRecord.


Oh, that helps! Thanks. I'm getting closer.

3- Which version of WebObjects are you using? You need WebObjects  
5.4 or better for generics to work.


Ok, right – I forgot that. I've been using a script to switch between  
WO 5.3 & WO 5.4. Using 5.4, this problem goes away.


So, I'm very close. But, I still get this as my first line:
package ${entity.packageName};

I'm trying to migrate over to Leopard and the latest WOLips, but  
having some problems.  I followed Mike's suggestion of setting up  
the frameworks with WebObjects53 and WebObjects54 directories and a  
WebObjects symlink - not sure if that's the problem or not:





I've tried importing an existing project, as well as creating a new  
project in the same directory as the existing framework, and both  
have the same problem - I can't get the WO Frameworks item to  
appear.  I tried messing around with the Libraries tab when setting  
the projects build path, but the dialog looks incomplete:





The version I downloaded today is : 3.3.4763

Any thoughts?

Thanks,
Ken

Ant Build Problem

[Joe Moreno]

Hi all:

	I've been having a problem with ant builds from the command line in  
Eclipse 3.3.1.1 with WOLips 3.3.4574.


	To isolate the problem, I created a Dummy project and when I run an  
ant build from the command line and then launch the app I still get  
the same error:


BUILD SUCCESSFUL
Total time: 0 seconds

[Macintosh:~/Projects/EclipseWorkspace/Dummy] % ./dist/Dummy.woa/Dummy

Any help is greatly appreciated.

Re: Unable to locate WOOpenURL on your computer

[Joe Moreno]

Are there any issues with simply coping WOOpenURL from Tiger into / 
System/Library/WebObjects/Executables?


I'm thinking it was left out for a good reason - but I'm not sure why.

Any ideas where I went wrong?  :-)



WOOpenURL is not included in Leopard anymore.

Hint from David LeBer:

sudo mkdir /System/Library/WebObjects/Executables // I think you  
need to do this
sudo ln -s /usr/bin/open /System/Library/WebObjects/Executables/ 
WOOpenURL

Mike and Pierre,

Thanks for pointing out the Relationship Wizard – that's a huge help.

	Now, I only need to use EOModeler 4.5.1 to view (read only) the  
models graphically (in diagram mode) and occasional data browsing.


Thanks for all the support,
Joe

I would very strongly advise you against doing that. There are new  
construct in the model for WO 5.4 that are supported by Entity  
Modeler that EOModeler does not know about and will very happily  
destroy. This is likely to lead to major disappointment, EOModeler  
check for a minimum version of the model but not a maximum so it  
will remove all the construct it does not know about. EOModeler save  
the model by doing a copy therefore anything it does not know about  
is forgotten and if my memory serves right WO 4.5.1 version does not  
know among other things about subversion.


You are only one key stroke away from disaster.

Re: WOCookie Issue & WOLips Timezone

[Joe Moreno]

Pierre,

Thanks for clearing up the cookie and time zone issue.
	I didn't know the problem with the time zone was a WO bug, I thought  
it was an Eclipse bug.


	Also, I've tried several different ways to delete the wosid cookie  
when I'm terminating a session without any luck.
	Can you recommend a good way to clear out or remove the wosid cookie?  
It seems like the WO R/R is overriding my settings.


Thanks,
Joe


On Jan 11, 2008, at 06:32:52, Mr. Pierre Frisch wrote:


Hi Joe,

Both are known bugs.

The GMT/PST bug will be fixed in the next update of WO.

The cookie issue unfortunately missed that update and will have to  
wait for the next one. The issue is that the cookie parsing is too  
strict and consider the empty value as a mistake so it trips on  
wosid=;. I have not developed a workaround yet except fixing your  
cookies.


Cheers

Re: PDF engine, that handles tables well

[Joe Moreno]

For simple PDF creation in WO, I'm real cheap...

I create a TXT files, and make a couple calls to the command line:  
ENSCRIPT to convert the TXT file to PS and then PS2PDF for the final  
PDF which I end up queueing in the LPR queue to fax out. It works  
surprisingly well for simple stuff.

Hi.

I have to build a PDF file with one big table that spans over a  
couple of pages. The information is tabular data, so something  
that can handle this automatically would be nice.

Java Release 6 issues?

[Joe Moreno]

This tricked me, I thought Apple had released Java 1.6.

	Anyway, is there any good reason not to upgrade on either Tiger or  
Leopard to the latest Java update?

Re: What happened to my WebObects option when creating a new project in Xcode 3.0?

[Joe Moreno]

I haven't upgraded to Leopard, yet, and I know all the WO tools have  
been deprecated on Leopard.
But, does Xcode still have the EOModel plug in? I know Xcode's  
rendering of EO Models wasn't that hot, but I just wanted to check.

Re: EOF Adaptor for Amazon's SimpleDB?

[Joe Moreno]

Well, since it's the Holiday Season, let me add this to my Wish List:

I'd also love a simple Amazon EC2 instance running WebObjects (WO  
frameworks and WO adaptor) that can be configured with JavaMonitor.


Or, even better, how about Amazon's EC2 running OS X Server (or at  
least Darwin)?


Ok, I'm back from fantasy land,

Re: Fat relationships: i.e. user <--->> transactions

[Joe Moreno]

My 2¢:

The following code snippet works for me in most cases, but, it  
doesn't work if the app tries to access the to-many relationship  
prior to saving the changes to the database.  Such access would fire  
the fault which would not contain the added object because it hadn't  
been saved to the DB, yet it should be in the to-many relationship in  
the app's object graph because it had been added.


public void holdFaultWhenAdding(EOEnterpriseObject eo, NSArray  
toManyArray) {

if(!EOFaultHandler.isFault(toManyArray)) {
 NSMutableArray array = (NSMutableArray) toManyArray;
 this.willChange();
array.addObject(eo);
}
}

When using the above method to hold faults, you’ll need to replace  
addToRelationship in your EO’s

custom class.

public void addToProducts(Product product) {
 this.holdFaultWhenAdding(product, this.products());
}


Does anyone have any experience with modeling the relationship both  
ways and simply turning off the to-many side as a class property for  
the _user_ side of a Web site but leaving the relationship as a class  
property for the_admin_ side?
I'm just thinking out loud, but it seems that both the _user_ and  
_admin_ apps could use the same EO Model but the _user_ app could  
load the model and then dynamically turn off the to-many relationship  
as a class property during run time.

It turns out to be almost never the case that you want to fetch  
all "Open Tasks".  It tends to be the case for us that you  
almost always want to have additional qualifiers on those  
searches, which ends up that you fault a HUGE (many thousands)  
of EO's in just to turn back around and filter them down in  
memory.  Instead, I can remove that relationship completely and  
provide just the variant of the to-many that takes a qualifier.


Of course not and I agree 100%. But the example was user <- 
>>transactions which *I* would not fetch manually unless I had  
problems with multiple instances.


And the case above would normally be in an SEC which would have  
no outgoing relations anyway.


  Well, it was my example, so I'll chime in (and change the subject)

...


  The _admin_ side often does. So I'm glad to hear there's a fix  
for the NSArray O(N^2) issue, that was in old Obj-C EOF as well.


  So removing the inverse relationship from a fat to-many isn't  
always an option if you need one in one place, and another in a  
different place.


  A pure EOF solution would be to dynamically define the to many  
side of
 user ->>transactions relationship at runtime, based on the  
particular application's needs.


  That was one of the nice things about Obj-C categories...I could  
load certain code in only certain places.

...

Suddenly I am reminded of some ObjC code I posted to this list on  
Apr 19 ("Re: AddObjectToBothSidesOfRelationshipWithkey") -- how to  
manipulate relationships in a clean(ish) fully EOF 4.5.1 way that  
avoids unnecessary firing of array faults.

OT: Exactly How Popular is WO?

[Joe Moreno]

It looks like WWDC 2005 put a little zip into WebObjects:

Obviously, the iPhone spiked in Jan and early summer of this year -  
and, as we head into the Holiday shopping season:

http://www.google.com/trends?q=iphone

And, finally, Xcode has been holding steady:

Component Actions: & encoding bug

[Joe Moreno]

Hi,	I was just recently bitten by WOContext's directActionURLForActionNamed bug:  The key/value pairs generated by this method are joined by & instead of just &. Obviously, that was a simple bug to work around (just replace & with & as Jeff Schmitz suggested).But, now for a tougher problem.	I have a component based hyperlink action - but, if the session has timed out I want to keep some state on the URL so I added the state into the WOHyperlink bindings in the same fashion as a direct action:ProfileHyperlink: WOHyperlink {	action = "">	?pageNumber = currentPage;	?wasLoggedIn = "y";	?wosid = wosid;}Guess what it does? It encodes the & as &When you mouse over the hyperlink it looks like this:If this image is stripped out by the discussion list then you can find the screen shot here:http://homepage.mac.com/jmoreno/.Public/WOAmpersandBug.png And the underlying HREF URL, generated by WebObjects, looks like this:/cgi-bin/WebObjects/MyWOApp.woa/wo/1dRbs2gZTtHj8lXzV8m3pg/0.5.3.0.0.1?pageNumber=5&wosid=1dRbs2gZTtHj8lXzV8m3pg&wasLoggedIn=yDoes anyone know a workaround for putting state on the URL when dealing with component based actions so that the ampersands aren't encoded?- Joe

Re: Keep WebObjects, Remove cgi-bin

[Joe Moreno]

Check,

Did you change the WOCGIAdaptorURL command line argument?   
WOApplicationBaseURL?


See http://developer.apple.com/documentation/WebObjects/ 
WOAppProperties/AppProperties/chapter_1_section_1.html


Chuck

Good point.


Did you change the WOCGIAdaptorURL command line argument?
Yes. But it didn't make a difference. I tried it several different  
ways, then, after checking the docs, I saw that WOCGIAdaptorURL  
doesn't make a difference: "This URL is used by the direct connect  
feature only."



Did you change the ...  WOApplicationBaseURL?
No. It is set to /WebObjects, which is the default. But, I did change  
it, after reading your comment, to workaround the problem...


Workaround
Here's what I did as a partial solution. I added a folder under  
Apache's doc root named WebResources. The WebResources folder is at  
the same level and has the same contents as the WebObjects folder  
with its app's Web server resources (same permissions too). I then  
changed WOApplicationBaseURL from /WebObjects to /WebResources and  
everything works fine. Of course, the engineer inside of me wants to  
know why it won't work with /WebObjects???


So, my workaround seems to work after an "extensive" 10 minutes worth  
of testing. I'm wondering if it'll have any future side effects when  
I need complete URLs for SSL/TLS, etc???


If you can recommend anything else I should look at then please let  
me know.


Thanks,
Joe

In a nutshell, you have to generate the URLs yourself.  There are  
many ways of doing this:


1. Create a class that generates the URL and use this with the href  
bindings on the components

2. Create a custom WOContext subclass to generate the URLS you need
3. Use regex to find and change the URLs in dispatchRequest in

Re: setting up SSL and certs

[Joe Moreno]

Gino,Does anyone know if it is possible to host more than 1 domain under https for name based hosting?If you're asking if you can host multiple SSL sites on the same server (machine) with different domain names then the answer is Yes. But, you'll need a separate public IP address for each SSL host. The reason is when a client and server communicate over SSL all their information is encrypted (except the source and destination IPs) including the headers (one of which contains the host name your connecting to - this is virtual hosting: multiple domain names on the same server with the same public IP address).So, the key is to assign multiple public IPs to the SSL server, one for each SSL certificate.Here's a sample (fictional) http  connection in the clear.

Re: Sorting objects using my own criteria

[Joe Moreno]

Miguel,	What type of criteria are you trying to sort by?	Here's a code snippet if you wanted to sort a relationship.	In this example there's a relationship between Cafe <--->> Menu	public NSArray orderedMenus() {		EOSortOrdering sortOrdering =			new EOSortOrdering("ordering", EOSortOrdering.CompareCaseInsensitiveAscending);		NSMutableArray sortOrderings = new NSMutableArray(sortOrdering);		NSArray orderedMenus =			EOSortOrdering.sortedArrayUsingKeyOrderArray(this.menus(), sortOrderings);		return orderedMenus;	}	But, since you're saying that alphabetic sorting isn't enough, then you might have to do what was done in the above example, which is add a field to your EO that is used specifically for sorting.	If you're trying to sort numerically, then you'll want to make sure that the database field is a number and not a string.- JoeOn Feb 17, 2006, at 11:08:29, Miguel Arroz wrote:Hi!  This is probably a simple question, but I'm not finding an answer... how can I sort objects in memory using my own criteria?
