Lachlan,

thanks, I thought of that. Leopard hosed my hostconfig file, so I put  
back HOSTNAME=localhost (the DNS server and my computer don't agree,  
so this overrides it); Eclipse uses a WO parameter for -WOHost  
localhost and so does wotaskd.


I did find one problem in the log it says:

Don't have permission to write to Configuration Directory /Library/ 
WebObjects/Configuration/ as this user; please change the permissions.


So I fixed that, and wotaksd then launched properly instead of trying  
over and over again.


However, I still can't connect to it on port 1085, and my Eclipse app  
still gives ...application was not found...


One thing that confuses me: in the wotaskd log it says:

main WebObjects version = 5.4

This is after I swapped out all the 5.4 frameworks and replaced them  
with 5.3. Should I worry about this?


Any other ideas?

Regards
Thomas

The community edition is free, and you get InnoDB and MyISAM with it.  
Basically the community edition lags a few dot releases behind the  
enterprise edition but is more or less the same product.

Thanks for pointing out.  I overlooked this as costing for commercial is always 
part of concerns.

To share a bit, these are some info I am able to dig out from MySQL support 
team email:

One commercial license is required for each server.
 For MySQL Classic, each commercial license cost US$395
 For MySQL Pro, each commercial license costs US$695

There are lots of other ways to address many of the steps I list  
here, and Apple now recommends that you use the jar versions of  
their frameworks instead of the .framework versions which I use, but  
I didn't want to rock the boat just yet -- this procedure I'm  
writing is all about getting things as close to normal again  
before we start doing other craziness over the next few days.  This  
is basically the how do I just get back to things working again  
tutorial.


Note, I did an upgrade install, so things may be a little different  
if you did a fresh install, but I suspect it would only be less  
things you have to do.


* Install Xcode Tools and select WebObjects so you get 5.4

* Make sure Web Sharing is enabled in the Sharing Prefs Panel

* Note: /etc/httpd is out, /etc/apache2 is in

* Edit /etc/apache2/httpd.conf (if you did a fresh install, you may  
already have these -- search httpd.conf first)

** search for rewrite_module, and above it, add a
LoadModule WebObjects_module /System/Library/WebObjects/Adaptors/ 
Apache2.2/mod_WebObjects.so

** go to the very end and add
Include /System/Library/WebObjects/Adaptors/Apache2.2/apache.conf
** Search for Directory / and comment out the Order and Deny lines:
Directory /
Options FollowSymLinks
AllowOverride None
#Order deny,allow
#Deny from all
/Directory
** Restart apache (apachectl restart as root)
** if you run ps auxw | grep httpd you should see apache now running

* Create /Library/LaunchDaemons/com.apple.webobjects.wotaskd.plist  
with:

?xml version=1.0 encoding=UTF-8?

* The following can be done a couple ways, but this is just how I  
happened to have things setup in betas, so I kept it (it worked for  
me):
** Make a /System/Library/Frameworks/WebObjects54 folder, and move

** Make a /System/Library/Frameworks/WebObjects53 folder, and move  
the following frameworks from your old 5.3 install into it (I tar'd  
these up from 5.3 before upgrading, but you can download 5.3 and  
extract these from the pkg, or POSSIBLY install them with the  
actually installer ... YMMV on that one)

Re: Are Batch Sequences Possible ?

Actually, I proposed an idea to FrontBase a while back, but totally  
forgot to revisit this once they open sourced the plugin.  The method  
you want to look at is in the plugin:


	public NSArray newPrimaryKeys(int i, EOEntity eoentity, JDBCChannel  
jdbcchannel) {


Notice it takes an int?  That int is the number of keys it needs.  If  
you extend the plugin, you can provide a more optimal implementation  
than just a for loop (which is what most of them do in here).

Mike recently added something to the FrontBase plugin(?) in Wonder

Oracle.  There are primary key generators in GVCEOFExtensions that  
also do this (get a batch from the DB and allocate them locally).


The method we used was  in EODatabaseContext's delegate interface,
databaseContextNewPrimaryKey(EODatabaseContext dbCtxt, Object

I'm not sure what Mike did for his.

Hi All,

Im currently developing an app against a Oracle databas, which uses  
sequence for generating its Primary Keys.


Is there a way to get WO to request a batch of sequences instead of  
doing it one at a time ( which is what it appears to be doing when  
you output the SQL ). For example I am doing 1 save to the database  
that is inserting 142 rows into 1 table, 142 into a second and 711  
into a third. Each of the 142 row table inserts takes 2 seconds to  
return all of the sequence while the 711 inserts take's 8 seconds  
to get the sequences. Thats 12 seconds used before it even starts  
the INSERT statements, which take another 2, 2 and 8 respectively.  
Meaning the total save time is 24 seconds ( with SQL debugging  
turned on, its a little quicker with it turned off ).


Please someone tell me Im doing something dumb, or that there is a  
better way.

Re: Database choices

When we spoke with MySQL a while back, I believe that you only have to  
pay the licensing fee if you BUNDLE mysql with your product.  That is,  
if you ship a product and mysql is inside of it, then you pay.  If you  
install MySQL separately, then you don't.  I even specifically asked  
them about this because it sounded very weird, phrasing it like I have  
in the previous sentence, and they agreed.  It's possible the  
licensing has changed since then (this was I believe in late 2005),  
but I doubt it.  So given that, most people aren't selling WO product  
bundles, and if they are they probably are not INCLUDING mysql in it,  
so it's unlikely that pricing actually affects WO people.

Is a Leopard version coming?
Thanks, Kieran


A very good question and one we've been thinking about a lot  
recently, so here is the Officical Rubicode Statement about  
EOGenerator and Leopard.


EOGenerator (and EOReporter and DBEdit for that matter) are based on  
the Objective-C version of EOF.  By using Objective-C, we were able  
to extend many EOF classes so that we could build our tools easily,  
and in EOGenerator's case, to add additional methods that were  
easily accessible in your templates..


As of WebObjects 5, Apple effectively EOL'ed the Obj-C EOF for  
public consumption, but because EOModeler and WebObjectsBuilder  
depended on those frameworks, they had to continue delivering them  
as private frameworks, which we gladly took advantage of.  However,  
we are well aware that as of 5.4, Apple has officially deprecated  
those applications as well as the private frameworks that we  
depended on.


It IS still possible to run these tools if you obtain the private  
frameworks and add them to your system from the previous developer  
release.  We have not tested this ourselves, but we have heard that  
it worked fine.


Currently we have no plans to make a version of DBEdit to work under  
5.4.  There is too much code, and too many Objective-C tricks  
required to think about a Java version at this time.


As for EOGenerator, that is a bit more difficult question.  We  
realize that EOGenerator is an extremely popular tool among the  
WebObjects community, and we would very much like to continue to  
support the tool, although neither Carl nor myself are working with  
WebObjects professionally at the moment.  We are left with two  
choices:  recreate the necessary Objective-C classes we need to  
support the model or rewrite the application in Java.  The first is  
not ideal as that places more work on our shoulders to stay in sync  
with the any changes to EOModel, and the latter would mean would  
sacrificing template compatibility to go with an existing Java  
product (most likely Velocity).  Either solution would certainly  
take a bit of time.


If we do redo EOGenerator, we will also redo EOReporter as the  
majority of the code base is the same.


Now Mike Schrag apparently has a EOGenerator replacement that he is  
looking to add to WOLips.  That is a completely separate project  
that we have no information about at this time, but we have every  
reason to believe that this will be a very useful tool that may  
remove any need for us to redevelop ours.  And if that happens we'll  
be content to hand over the EOGenerator title to someone else,  
although we will miss it.


We have greatly enjoyed serving the community with these tools for  
the past 7 years and are quite impressed with how many of you have  
made EOGenerator part of your projects.  We are looking forward to  
what Mike has to offer and will be exploring what we can add to the  
community also.

Hi!

  Well, yeah! :) I'm using a virtual host, and, on leopard, the only  
way I could do it was setting the machine hostname to the same as the  
virtual host. So, if your virtual host is something like myApp.mac,  
do a sudo hostname -s myApp.mac. It started working after that. Of  
course, if you want to work with more that one vhost at the same  
time, then you may have problems.

thanks, I thought of that. Leopard hosed my hostconfig file, so I  
put back HOSTNAME=localhost (the DNS server and my computer don't

WOHost localhost and so does wotaskd.


I did find one problem in the log it says:

Don't have permission to write to Configuration Directory /Library/ 
WebObjects/Configuration/ as this user; please change the  
permissions.


So I fixed that, and wotaksd then launched properly instead of  
trying over and over again.


However, I still can't connect to it on port 1085, and my Eclipse  
app still gives ...application was not found...


One thing that confuses me: in the wotaskd log it says:

main WebObjects version = 5.4

This is after I swapped out all the 5.4 frameworks and replaced  
them with 5.3. Should I worry about this?


Any other ideas?

Thomas

Re: Database choices

2007-10-30 Thread John Huss

We use FrontBase for an application that does mostly large, complex queries
(aggregating data, etc).  A few things about FrontBase have bothered me and
made me consider switching to Postgres:

- The database process crashes sometimes due to various queries that it
doesn't like
- Left join performance is bad
- Legacy left join syntax can return incorrect results
- OR performance is bad
- Multi-column indexes only allow a range of values for the last column of
the index - resulting in bad performance
- Adding columns to large tables can take hours and makes the DB
unresponsive

So I would say that FrontBase is great for applications that do simple, fast
queries, but maybe not if your needs are more demanding.

As far as I understood Geert, this will not reclaim space on disk.  
You'll have to do a backup/restore cycle to get that back.


We had that problem with a fairly large logging database, where the  
space on disk doubled after an optimize - to 40GB ... And backup /  
restore takes too long to tolerate the downtime.


Yes!  FB has a query plan output also, but it's worthless.  It's  
totally cryptic and doesn't nearly report enough information about  
what it did.  My kingdom for them to make this better and on par  
with most of the competition.


Yes, same feelings here. I'd love to see something like explain  
analyze ... on FrontBase. The output in FrontBase only told me, that  
it was using some indexes for this and that, but that's about it.



Can't you just pg_dump your tables?


Sure you can, but than you have just one monolithic backup. And point  
in time recovery, what FrontBase backup does if you keep transaction  
logs, is on PG just plain pain in the ... wherever. FrontBase is  
easier to setup with that and just works (at least it did for us).  
PITR in PostgreSQL requires for a non-dba some serious shell scripting  
testing and digging until it works as expected. And even than it is  
not nice.


For a dba, this might sound ridiculous, but for me it isn't.

And just for completeness, I always have strange problems with FB  
Backup/Restore -- For one, they're not endian-safe, so you can't  
backup and restore across architectures, which just sucks.


You can't do either with PostgreSQL PITR (basically wal archiving). We  
found, that it mainly works from a Linux 64 bit Suse box to a Mac OS X  
Server (Leopard), 64 Bit compiled PG, if you recreate all indexes on  
the Leopard machine or use a plain C locale.


For another, it seems to segfault under odd circumstances for me  
when I try to move across machines, even of the same architecture.   
I write backup and also write all output just to be safe (write all  
output is actually not transactionally safe on FB, but I like to  
have it as a just in case in the event of an emergency).


I do the same.

Another wish I have is if I add a fulltext index, that I could tell  
it to make '%whatever%' queries use LookSee so I don't have to  
resort to proprietary SQL to do it.
I know WHY they don't do this, but it would just be a little nicer.   
I always mean to write a FullTextQualifier in Wonder that will turn  
into the proper SQL for a full-text search in the various databases,  
but I never seem get around to it.


Maybe this will appear one day if you ignore it long enough? Who  
knows? :-P


Yeah I would agree with this, too ... And we mix and match.  The  
other one is that PG has a much better query optimizer.  If you ever  
do a left outer join in FB, you may find that under certain  
circumstances performance really sucks.  We had to switch one of our  
apps over to PG which handed FB its ass in query performance with a  
complex query over a fairly large dataset.  For straight WO, this  
turns out to not matter much, because WO tends to generate fairly  
simple queries, but if you ever have particular complex custom SQL  
fetches, you might run into it.


We had the same problem about two years ago when I was still working  
in Germany, and it was really a pain. The planner did an obviously  
wrong choice (doing a nested loop or something similar over a set of  
more than 100k rows ...) where it could just use a subset (or  
subselect). The query was generated by D2W, so not much I could do  
about that without hacking way to deep and loosing all the nice, fast  
and easy development. I switched this app to PostgreSQL which handled  
that case way better.


As far as I know, FrontBase has solved this by bringing the query  
optimizer that was planned for version 5 into version 4. It solved the  
problem for the queries I had, but was still about a factor of two or  
three slower on that kind of stuff than FrontBase was. And we were on  
fairly old hardware and needed the speed. So we stayed with PG for that.


But to be fair: if you run into that kind of problem, the guys at  
FrontBase really want to help you and normally they find a way quickly.

coexisting installs of WO 5.3/5.4 on Tiger/Leopard?

2007-10-30 Thread Ray Kiddy



I am wondering what people think about these (very random) ideas.

I have to admit I have not jumped onto using a Leopard system yet.  
For one thing, I have midterms, and for another, I am tempted to wait  
until I can get hardware with Leopard on it (which I probably cannot  
yet) and get a new laptop with Leopard on it. Then I will be able to  
transition things over from my current laptop as I desire, and not  
try to upgrade my somewhat beat-up laptop.


I am pretty sure of some things, some of which are represent  
competing viewpoints:


1) WO 5.3 is not and will not be supported on Leopard.

2) WO 5.3 works with Java 1.4, which is on Leopard, and so the WO 5.3  
runtime should work on Leopard.


3) It has been possible, for quite a while, to have more than one  
version of WO on a machine, but Apple will never support this.  
Essentially, the theoretical cost of supporting configuration goes up  
exponentially, not linearly, with the number of versions on a system.  
There will never be a reason for Apple to take on the job of  
supporting a machine that has two different versions of WO. But


Having no tool support, it should be a lot easier to configure  
runtimes for multiple versions. Things like soft-linked directory  
branches work a lot better when they do not have to deal with the  
ObjC bridge and all its associated noise. Project Wonder, for  
instance, could include scripts for configuring this. A script could  
even check the integrity of deployment installs. While at Apple, I  
wrote a verify your versions direct action. Too support-ish and not  
enough aqua, so not shippable.


4) EOModeler and WebObjects Builder may work on Leopard, but one  
would have to get the apps and many of their private frameworks over  
by hand and Apple may have done something to make these apps not  
launch, or they will launch but be crashy in the extreme. I still use  
them on Tiger, but I will have to give up on them for Leopard. :-(


Has Apple announced a public API for plugins in Xcode? Probably not.  
The amusing thing is, Xcode being an ObjC app, there are lots of APIs  
used by the plugins that Apple has written. That's actually the crux  
of the biscuit. Each group of people doing a plugin or two has  
created a new internal API


I know I should take the time to get comfortable with Eclipse. I just  
have had other things to do. Like creating WO apps. Sorry.


6) I am willing to bet I can take Xcode templates for WebObjects  
projects and make them work in Leopard. It should not even be  
difficult. Project templates are, after all, just a resource. I  
cannot decide if this is worth any time.


I am sure I will come up with other ideas, some even more useless  
than some of these, when I actually have a Leopard system. We'll see.  
I am open to suggestions, question, jibes, innuendoes, catcalls, or  
anything short of insults. No, insults are ok, too. :-)


happy halloween - ray

Is a Leopard version coming?
Thanks, Kieran


A very good question and one we've been thinking about a lot  
recently, so here is the Officical Rubicode Statement about  
EOGenerator and Leopard.


EOGenerator (and EOReporter and DBEdit for that matter) are based  
on the Objective-C version of EOF.  By using Objective-C, we were  
able to extend many EOF classes so that we could build our tools  
easily, and in EOGenerator's case, to add additional methods that  
were easily accessible in your templates..


As of WebObjects 5, Apple effectively EOL'ed the Obj-C EOF for  
public consumption, but because EOModeler and WebObjectsBuilder  
depended on those frameworks, they had to continue delivering them  
as private frameworks, which we gladly took advantage of.   
However, we are well aware that as of 5.4, Apple has officially  
deprecated those applications as well as the private frameworks  
that we depended on.


It IS still possible to run these tools if you obtain the private  
frameworks and add them to your system from the previous developer  
release.  We have not tested this ourselves, but we have heard  
that it worked fine.


Currently we have no plans to make a version of DBEdit to work  
under 5.4.  There is too much code, and too many Objective-C  
tricks required to think about a Java version at this time.


As for EOGenerator, that is a bit more difficult question.  We  
realize that EOGenerator is an extremely popular tool among the  
WebObjects community, and we would very much like to continue to  
support the tool, although neither Carl nor myself are working  
with WebObjects professionally at the moment.  We are left with  
two choices:  recreate the necessary Objective-C classes we need  
to support the model or rewrite the application in Java.  The  
first is not ideal as that places more work on our shoulders to  
stay in sync with the any changes to EOModel, and the latter would  
mean would sacrificing template compatibility to go with an  
existing Java product (most likely Velocity).  Either solution  
would certainly take a bit of time.


If we do redo EOGenerator, we will also redo EOReporter as the  
majority of the code base is the same.


Now Mike Schrag apparently has a EOGenerator replacement that he  
is looking to add to WOLips.  That is a completely separate  
project that we have no information about at this time, but we  
have every reason to believe that this will be a very useful tool  
that may remove any need for us to redevelop ours.  And if that  
happens we'll be content to hand over the EOGenerator title to  
someone else, although we will miss it.


We have greatly enjoyed serving the community with these tools for  
the past 7 years and are quite impressed with how many of you have  
made EOGenerator part of your projects.  We are looking forward to  
what Mike has to offer and will be exploring what we can add to  
the community also.

One very good reason is that they depend on and require system  
libraries (aka frameworks) that are no longer part of OS X (as of  
Leopard).  Apple can not (for very valid reasons) release these  
system libraries as Open Source.  Without them, the apps are of  
little value.

Yes, something odd is going on there.


If you stay inside one column with your or its using an index, if  
you use two different columns in an or, it won't. E.g.:


select * from foo where a = 'bar' or a = 'bas';

will use an index, but:

select * from foo where a = 'bar' or b = 'bar';

will not.

For now, until a new solution arrives, you can just copy the needed  
Frameworks to you /System/Library/PrivateFrameworks and /System/ 
Library/Frameworks folders.


I moved the following from my Tiger install to /System/Library/ 
Frameworks:


InterfaceBuilder.framework
EOModeler.framework

And to /System/Library/PrivateFrameworks:

DevToolsCore.framework
DevToolsRemoteClient.framework
DevToolsSupport.framework
JavaKit.framework
EOAccess.framework
EOControl.framework
EOInterface.framework

With that, EOGenerator seems to work fine for me. I haven't noticed  
any problems yet, but I did this only this morning, so no guarantees  
that everything works.

For example, the FrontBase mail list archive has this message:

Subject: [RESOLVED] Re: Optimization/Caching/Indexing how-to

The order of the columns in the composite index definition is very important
for your case.

If you want the optimal performance, you need to put the timestamp column
last in the index definition because it is used with a range. The server
cannot use the column of an index after one with a range qualifier.

For example, in your case, if your composite index is define like these
example with a = check on fkY and fkZ and a range on dateX:
- (dateX, fkY, fkZ), only the date columsn is used like an index (dateX)
- (fkY, dateX, fkZ), only the fkY and date columsn is used like an index
(fkY, dateX)

Re: Database choices

2007-10-30 Thread Shehryar Khan



If you're going to use MySQL with WebObjects in a production  
environment, make sure to do the following:


- create all your tables with InnoDB engine support - the default  
MyISAM support is non-transactional


- make sure to create all your tables with the right charset and  
collation (UTF-8 all the way).  MySQL's internationalization support  
is excellent but ONLY if configured properly.


- make sure to add the correct voodoo to the JDBC connection string  
for your application so that it uses the right charset / collation  
over the JDBC connection.


While MySQL has worked out quite well for us when used with  
WebObjects (and PHP), the lack of sequences makes it a less viable  
choice for projects going forward.


These days we go out of our way to design schemas that are  
WebObjects, Ruby on Rails, Hibernate, and PHP friendly.  The MySQL /  
EO_PK_TABLE paradigm just doesn't fit well in this methodology -  
PostgreSQL is a much better choice.


thanks!

There have been many mails on WO passing. First of all it didn't until  
now, and it won't for some time (at least that is what I think). But  
anyway. With the introduction of Webobject 5.4 and Leopard we've seen  
two things:


1. Java isn't top priority anymore (look at Java 6 not being there...).
2. Therefore also Webobjects can't be.

They didn't even manage to launch a new webobjects homepage  
synchronized with the release of Leopard and in Server Features it  
isn't leasted under the key technologie section. And to be honest, the  
progress they made since 5.3 in my view is a little dissapointing  
altough going in the right direction. They now mainly rely on help  
from the superbe wonder community for tools and anything. But in the  
end their pushing other technologies in place...

scp is particularly slow if you transfer the built embedded bundle  
as is with each file transfered separately . however if you  
tar.gz the bundle, it makes a dramatic difference to upload .


Sure, and this is what I do. But it's still bigger than it needs to be.

For the extra 60 seconds upload, I find it refreshing to never have  
deployment launch problems and peace of mind that I never stomp  
over frameworks with new versions that are incompatible with  
existing deployed apps.


For sure, a dedicated server with one or two apps might make sense  
to manage the server frameworks as separate deployments, but IMHO  
for servers with 6 or 12 or more different apps where some might  
not get updates for a long long time, embedding is the best way to  
deployment sanity.


I really don't see the conceptual difficulty with the following:

instead of:
WOROOT/Library/Frameworks/JavaEOAccess.framework/Resources/Java/ 
javaeoaccess.jar


use in Contents/Unix/CLASSPATH.txt for example:
WOROOT_53/Library/Frameworks/JavaEOAccess.framework/Resources/Java/ 
javaeoaccess.jar

...

Simply requires either org.objectstyle.woproject.ant.WOApplication to  
take some argument or some other ant call to regex-replace after the  
fact.


So for me, if there's some work put into a better solution, then  
+1 from me. (This may just mean adding an option to WOLips to set

I don't believe this is the case.  First of all, their release plan  
with Java 6 basically matches their behavior with all previous  
releases of Java and demonstrates to me that it's as important as it's  
always been (whether that is high importance or not, who knows, but it  
seems at  least consistent). There's a huge amount of speculation  
about what's going on, but I suspect the answer is it's coming out  
really soon, chill people.  All these folks on the blogs who are so  
worked up about Java 6, I'm curious what exactly the features are of 6  
that they're really that upset about not having right now?  It seems  
to me Sun's pretty well lamed up the Java 6 release -- give me some  
REAL features, Sun -- don't just bundle a damn database in your VM.   
This is not by any means an excuse for Apple to delay releasing, I'd  
love the latest and greatest also, but looking at the differences, I'm  
not really all that upset.


Secondly while 5.3 in many ways is just catching up with what Wonder  
and others have had for a while, I think it's forward momentum, and  
that's a good thing for the platform.  Wonder has had 7 (or so) years  
of active development while WO has mostly stood still, so yeah, it's  
going to take a while to figure out what makes sense to go into the  
platform and for them to bring those features in.  And while I've  
disagreed with some of the specific 5.4 decisions, I think Pierre,  
Daryl, and crew have good intentions for the platform and I know  
they're actively working on making it better.  Apple could have  
decided to not put a single more man hour into WO development, but  
instead they've made a fairly substantial turn in the past year or so  
and are actually trying to offer new developments.


I do agree that the WO 5.3 webpage on Apple's site is pretty lame, but  
it's also a technology in a weird place at the moment.  Do they show  
WOLips pictures there? Maybe, but I'm not sure there's much of a  
precedent for that. Give it time to work itself out.  And honestly, if  
it doesn't, so be it.  You're still using one of the best technologies  
around, and Apple not doing a damn thing for almost a decade hasn't  
really held you up thus far.

- (dateX, fkY, fkZ), only the date columsn is used like an index  
(dateX)
- (fkY, dateX, fkZ), only the fkY and date columsn is used like an  
index (fkY, dateX)

Re: Regarding Final Note

And by the way, the move from Xcode + WOB + EOM to Eclipse + WOLips +  
EM is really no different than Apple's move from the old iMovie to  
iMovie 08.  The big point of contention is that it's neither a clear  
upward or downward move.  In some ways it's substantially better, in  
some ways it's worse, but, like Apple with iMovie, we (being WOLips  
and Apple) collectively believe that even though we took a step down  
in some areas, the overall trajectory of this direction is much  
stronger.  I fully believe this for WOLips.  Yes, graphical editing of  
tables isn't there yet, and you can't drag and drop bindings yet, but  
there's a HUGE amount of new stuff that IS there that makes a much  
stronger development platform to work off of.  Think different ;)

1. Java isn't top priority anymore (look at Java 6 not being

2. Therefore also Webobjects can't be.

They didn't even manage to launch a new webobjects homepage  
synchronized with the release of Leopard and in Server Features it  
isn't leasted under the key technologie section. And to be honest,  
the progress they made since 5.3 in my view is a little  
dissapointing altough going in the right direction. They now mainly  
rely on help from the superbe wonder community for tools and  
anything. But in the end their pushing other technologies in place...

suggestion: embed=true for all frameworks solved much of this

The thing I /do not/ like about embedding of WO supplied frameworks  
is how this makes each app needlessly bulky for uploading.


scp is particularly slow if you transfer the built embedded bundle as  
is with each file transfered separately . however if you tar.gz  
the bundle, it makes a dramatic difference to upload . I find  
that a typical woa with fully embedded Apple frameworks, Wonder and a  
few custom ones tar.gz's to 15MB to 30MB more or less.  it is  
faster than when I scp'd non-tar.gz'd, non-embedded woa's before from  
what I can see.


For the extra 60 seconds upload, I find it refreshing to never have  
deployment launch problems and peace of mind that I never stomp over  
frameworks with new versions that are incompatible with existing  
deployed apps.


For sure, a dedicated server with one or two apps might make sense to  
manage the server frameworks as separate deployments, but IMHO for  
servers with 6 or 12 or more different apps where some might not get  
updates for a long long time, embedding is the best way to deployment  
sanity.




So for me, if there's some work put into a better solution, then +1  
from me. (This may just mean adding an option to WOLips to set a  
custom location to find the system frameworks).

Re: The Official What-I-Did-To-Run-5.3-On-Leopard Post


OK, just to be simple I've removed virtual hosts, without change.

I've tried all sorts of HostName combinations, but I believe that is a

I believe that the real problem is that wotaskd is not listening on  
port 1085. I can't connect to it with a browser, and although ps tells  
me wotaskd was launched with ... -WOPort 1085 ... netstat does not

I guess I'll just give up on Leopard development for now, and use an  
older 10.4 machine to do development. Direct connect is not an option,  
because my apps use mod-rewrite and readable URLs for most links.

 Wait, are you answering for WO 5.4 or the WOLips validator. This sounds like
 the WOLips validator, which also sounds like a bug that you can't use name =

 haven't tested this out.
 
 Well, I used name=whatever inside quote, and it worked in WO 5.3  (I've not
 5.4), but I remember I used it also in another component and in the runtime (I
 don't remember the class, while generating the HTML) it gives an exception
 (Tag Not Valid if I remember, sorry but It was last year). After I remove the

JavaEOGenerator


OK Leopard EOGenerator waiters ...

After much legal gnashing of teeth, and some poking and prodding,  
Apple has agreed to release JavaEOGenerator.  This is 100% work done  
by Apple.  I'm just releasing it on mDimension build server while they  
get their ducks in a row on their own proper release.  This will  
eventually be a developer example in some forthcoming Leopard  
developer update, which means it will also include source code.  I'm  
only providing the binary release at the moment, though a source  
release may also be coming prior to a Leopard release also.


You can download JavaEOGenerator from:

http://webobjects.mdimension.com/wolips/EOGenerator/JavaEOGenerator-beta.tar.gz

and you can get the sample templates from:

http://webobjects.mdimension.com/wolips/EOGenerator/JavaEOGenerator%20Templates/

The template format is WO 5.4 inline bindings, so it should feel  
familiar.  There is a README.rtfd inside the tar that explains more  
about how to use it.  Other than the template format changing, this  
should be a 100% drop-in replacement of the original EOGenerator.


Going forward this will likely be the recommended method for  
EOGeneration.


Thanks a lot to Apple for contributing this to WOLips!

Re: Setting a custom EOFetchSpecification for a WODisplayGroup

2007-10-30 Thread Paul Hoadley


On 29/10/2007, at 9:30 PM, Paul Lynch wrote:


I am very much a WO novice, just working my way through Ruzek's WO
web application construction kit.


WOWACK is a little old now, being WO 4.5; but I still like it the

Yes, it still seems to be usable.  Well, it was usable given I had  
worked through about half of it before upgrading to Leopard and losing  
the Apple GUI tools.  I don't know how someone would go starting from  
scratch with WOWACK now...



What I
_thought_ I could do was replace the literal declaration of
fetchSpecification for the WODisplayGroup (which I just copied over
from something auto-generated from WO Builder) with a reference to a
method in the component's Java class that returned an
EOFetchSpecification.  That is, instead of this:

   dataSource = {
   class = EODatabaseDataSource;
   editingContext = session.defaultEditingContext;
   fetchSpecification = {
   class = EOFetchSpecification;
   entityName = Task;
   fetchLimit = 0;
   isDeep = YES;
   };
   };

I tried this:

   dataSource = {
   class = EODatabaseDataSource;
   editingContext = session.defaultEditingContext;
   fetchSpecification = activeFetchSpec;
   };



Try:

fetchSpecification = activeFetchSpec;

for your binding, assuming that this is a method in the component  
that returns a fetch spec.


That didn't _seem_ to work (it was the method returning an  
EOFetchSpecification), but I've now changed several things since I  
asked the question, most notably upgrading to WO 5.4.  I've also  
ditched the idea of using WODisplayGroups in the application anyway.   
If I take another look at it later and work it out, I'll reply to the  
list.

anything else, but I don't know why it would use any OS X-specific code.

Re: Regarding Final Note

What I would love to see is a simple download and install package  
for WO developers.
The biggest issue with this is that someone has to host the extra 100+  
meg installer for a bunch of leeches to download :)  But anyone could  
technically make a preinstalled bundle.


For example, the recommended Eclipse 3.3.1 and stable WOLips for  
WO5.4 development.


Not sure if it's possible but that would be nice.

And maybe bundle a README file with links pointing users to places  
pages where they can find more info.  Since most real projects  
consist of reusable frameworks and applications that use them, I  
think a tutorial should cover how to build a framework and add that  
dependency to one of your apps.

Have you seen the wolips wiki?  It has all of this.

Re: The Official What-I-Did-To-Run-5.3-On-Leopard Post


Chuck, you're a genius.

sudo lsof -i tcp:1085

-  tells me that wotaskd is listening on the reverse DNS entry for  
this machine. So when I use that host name in the browser, wotaskd  
delivers its page. No, it's not password protected. But I didn't  
realise that wotaskd refuses to respond to the wrong host name--  
connection refused.


And because wotaskd is listening on the reverse DNS entry, localhost  
doesn't work either.


So I changed all the config files to use the reverse DNS name, and at  
last I can connect to Eclipse via Apache.


Now I have to see what I can do about the virtual hosts.

Just BTW, at the start of /etc/hostconfig it says this file is going  
away and adding HOSTNAME=... to it didn't seem to do anything useful.  
How am I supposed to tell my development machine that its name should  
be different to the reverse DNS entry (which is very hard to get  
changed)?

I was wondering about that when you mentioned something about the DNS  
not matching.  I was hoping this was fixed in WO 5.4.  WO is very  
sensitive to problems in this area.  I suspect, but don't know, that  
different developers used different methods of resolving things at  
different places in the code.  If the reverse DNS does not match the  
host name you are trying to use, things just don't work.


That is also a little odd if you have
WOHost=localhost

in the Properties files of wotaskd.woa.  It _should_ use that, unless  
something else is getting specified on the command line somewhere.

I don't know the answer to that, OS X sys admin is not my strong

anything you can do.

Yes, I was launching wotaskd as per the initial email in this thread.

And for the next exciting episode in the journey-- virtual sites and

Re: Are Batch Sequences Possible ?


I'm not sure what Mike did for his.
OK, I committed a fix to the FrontBasePlugin that adds batch key  
generation ... Right now it just does batches of 10, but it can be  
tweaked pretty easily.  I'm using the syntax of:


values (select unique from YourTable, select unique from YourTable,  
select unique from YourTable, ...)


which is how Geert recommended that this be addressed.  I suspect I  
could do WAY more than 10 as FB seems to just not care how big of a  
query you throw at it, but oh well .. 10x faster isn't bad either.

Re: Are Batch Sequences Possible ?

2007-10-30 Thread Owen McKerrow


Hi Chuck,

I'm looking over your FBIntegerPrimaryKeyGenerator and  
IntegerPrimaryKeyGenerator classes from GVCFrameworks and was just  
wondering if my understanding of it is correct. Basiaclly you will  
have to make a new instance of the FBIntegerPrimaryKeyGenerator at  
some point and then ask it to create a bunch of new PK's for you for  
a specific entity, lets say Person. These are then cached. So then  
when I make a new instance Person, it will be given one of these  
caches PK's stright away ( i.e. no extra code required ) or is there  
another step to request one of these PK's from the cache ? If it  
happens automatically will it be before the editingContext saves it  
changes ?


I could see this potentially being dangerous ( not deadly or  
anything ) if you don't end up using all your primary keys ( at least  
with Orcale sequences ) in that you would ask for 100 new PK's, the  
sequence is incremented 100 times, you only use 50 of them and you  
would have a missing 50 values from your PK coloum. Anyways just a  
random though.

Hi All,

Im currently developing an app against a Oracle databas, which  
uses sequence for generating its Primary Keys.


Is there a way to get WO to request a batch of sequences instead  
of doing it one at a time ( which is what it appears to be doing  
when you output the SQL ). For example I am doing 1 save to the  
database that is inserting 142 rows into 1 table, 142 into a  
second and 711 into a third. Each of the 142 row table inserts  
takes 2 seconds to return all of the sequence while the 711  
inserts take's 8 seconds to get the sequences. Thats 12 seconds  
used before it even starts the INSERT statements, which take  
another 2, 2 and 8 respectively. Meaning the total save time is 24  
seconds ( with SQL debugging turned on, its a little quicker with  
it turned off ).


Please someone tell me Im doing something dumb, or that there is a  
better way.

Re: Are Batch Sequences Possible ?

Hi Chuck,

I'm looking over your FBIntegerPrimaryKeyGenerator and  
IntegerPrimaryKeyGenerator classes from GVCFrameworks and was just  
wondering if my understanding of it is correct. Basiaclly you will  
have to make a new instance of the FBIntegerPrimaryKeyGenerator at  
some point and then ask it to create a bunch of new PK's for you  
for a specific entity, lets say Person. These are then cached. So  
then when I make a new instance Person, it will be given one of  
these caches PK's stright away ( i.e. no extra code required ) or  
is there another step to request one of these PK's from the cache ?  
If it happens automatically will it be before the editingContext  
saves it changes ?


Yes, that sounds correct.  We have only used this when processing  
large imports that insert thousands of rows.  The PK assignment from  
the cache happens during saveChanges().  IIRC, it if runs out it will  
cache another batch.



I could see this potentially being dangerous ( not deadly or  
anything ) if you don't end up using all your primary keys ( at  
least with Orcale sequences ) in that you would ask for 100 new  
PK's, the sequence is incremented 100 times, you only use 50 of  
them and you would have a missing 50 values from your PK coloum.  
Anyways just a random though.


Yes, it will create gaps in the PK sequence.  That is the price to be  
paid for caching.  I was discussing this with Mike earlier and it  
appears that our code may have a nasty race condition in it.  SELECT  
UNIQUE might not be working as we had assumed.  I have not gotten  
around to testing it yet.  The solution in the plugin that Mike just  
posted about is (a) safe from this race condition, (b) less wasteful  
of key values, and (c) overall easier to use.  We were too short  
sighted to consider doing it at the plugin level when we wrote that  
PK key caching code.

Short answer: yes.

Mike recently added something to the FrontBase plugin(?) in Wonder  
to do this.  I imagine that the same thing could be done for  
Oracle.  There are primary key generators in GVCEOFExtensions that  
also do this (get a batch from the DB and allocate them locally).


The method we used was  in EODatabaseContext's delegate interface,
databaseContextNewPrimaryKey(EODatabaseContext dbCtxt, Object  
object, EOEntity entity)


I'm not sure what Mike did for his.

Hi All,

Im currently developing an app against a Oracle databas, which  
uses sequence for generating its Primary Keys.


Is there a way to get WO to request a batch of sequences instead  
of doing it one at a time ( which is what it appears to be doing  
when you output the SQL ). For example I am doing 1 save to the  
database that is inserting 142 rows into 1 table, 142 into a  
second and 711 into a third. Each of the 142 row table inserts  
takes 2 seconds to return all of the sequence while the 711  
inserts take's 8 seconds to get the sequences. Thats 12 seconds  
used before it even starts the INSERT statements, which take  
another 2, 2 and 8 respectively. Meaning the total save time is  
24 seconds ( with SQL debugging turned on, its a little quicker  
with it turned off ).


Please someone tell me Im doing something dumb, or that there is  
a better way.

It's not directly required, but it would be nice to have Jad and Jadclipse
included if it's all legal and everything.  And mdimension has an update
site for Jadclipse that could be set up in the Update Manager.

Maybe this is going to far though.

You can download JavaEOGenerator from:

and you can get the sample templates from:

http://webobjects.mdimension.com/wolips/EOGenerator/JavaEOGenerator%

The template format is WO 5.4 inline bindings, so it should feel  
familiar.  There is a README.rtfd inside the tar that explains more  
about how to use it.  Other than the template format changing, this  
should be a 100% drop-in replacement of the original EOGenerator.


Going forward this will likely be the recommended method for  
EOGeneration.

Mike doesn't work for Apple, he works for mDimension. Both mDimension  
and ObjectsStyle host and pay for a pretty substantial chunk of the  
WO community infrastructure that we rely on daily. They pay the  
hardware, hosting and bandwidth bills, you and I and everyone else  
suck down the content time after time, giving nothing in return, and  
paying exactly nothing to them for the pleasure. That's not even  
taking into account the enormous number of man hours of code  
development these companies donate to the community. So suck it up  
sunshine, we are leeches.

Re: AJRDatabase + MiscMerge ?= NeoEOGenerator

2007-10-30 Thread Doug McClure

Hi Jason,

We are actually looking at AJR.  I've managed to compile it into EOGenerator
but it's naturally missing information about Java, and we're having some
Key-Value coding issues it seems so we are a fair decent ways away from
actually making a template work.  And probably the biggest issue will be
figuring out how to deal with the new prototype support in 5.4.

Seriously, Ken, are you kidding me?  I can't even believe I'm about to  
respond to this.


Everything below is my own opinion and not that of my employer blah  
blah blah.


First and most importantly, there's a _fairly crucial_ :) at the end  
of that sentence -- clearly I meant that as a joke.  Secondly, that  
you're accusing me of being part of the problem really is the most  
insulting thing I've ever heard, and I really REALLY don't get  
offended easily.  The rest of this is going to come off sounding self- 
congratulatory, and I'm really not like that, and it's not why I do  
the things I do, so bear with me everyone else for a moment and then  
we can pretend this email never happened.


My company has donated a running tally of more than $75,000 worth of  
COMPLETELY free development time to this community.  We have donated  
MANY hundreds  of gigabytes of free bandwidth and hosting to provide  
nightly build servers for WOLips, Project Wonder, and maven  
repositories.  And more importantly I have given up I don't even KNOW  
how many hundreds of hours of my personal life that I could be doing  
any number of other things with to try to make it a little better for  
the WO community.  Do you know what I was doing this weekend?  I  
wasn't playing with my son, I was instead stressing out about getting  
all the open source frameworks and applications 5.4 ready, and working  
through a list of procedures to try and help people migrate to Leopard  
with as few bumps as possible.  I actually DO have both a life and  
real work outside of all of this.  All those times I'm responding to  
emails and building new features in WOLips is time that comes from  
somewhere -- it means I'm pushing off my life or real work that I have  
to do later.  The first release of Entity Modeler was written in 5  
weeks of 100% personal time when I found out that EOModeler was likely  
going to be killed.  In fact, it's currently 2am and I just happened  
to have switched over to Mail from my Eclipse where I was working on  
building an early SWT release to work around a crashing bug that you  
new people might run into in Eclipse 3.3.1, but I really wanted to get  
it built so new users (that i apparently despise so much) don't have  
to get pissed off by crashes and have to wait until 3.3.2 comes out.   
Honestly -- am I really defending myself here?


So I apologize that the humor of my offhand snarky comment was CLEARLY  
lost on you, but I recommend that you maybe peruse this mailing list  
for more than a couple minutes before you make comments like this,  
because it makes you look pretty foolish.  And the irony of this  
situation is that when Jeremy finishes packaging up a WOLips  
installer, we WILL host the damn thing on our build server.


Wow ... Just ... wow.

Is there an example that uses the new WO component format?
