Problem with pages saved in a variable
Dear List,
in an Applications Session, a NSMutableDictionary object is used for
caching pages. Everytime the pageWithName method is called, the
dictionary is queried in order to determine if the requested page does
already exist, if true the existing page is returned, else a new one is
generated and stored in the dictionary. This is made in Application.java
by overriding the pageWithName method:
public WOComponent pageWithName(String aName, WOContext aContext) {
Object result = null;
if ( aContext.hasSession() ) result =
((NSMutableDictionary)((Session)aContext.session()).cachedPages()).objectForKey(aName);
if ( result == null ) {
result = super.pageWithName(aName, aContext);
if ( aContext.hasSession() ) if ( aName != null )
((NSMutableDictionary)((Session)aContext.session()).cachedPages()).setObjectForKey(result,
aName);
}
return (WOComponent)result;
}
This works with one exception. Making changes on Enterprise Objects is
not possible in every case. Saving changes works, if always the same
object is changed but not if two different objects are changed (changing
the first, saving the changes, then changing the second and saving the
changes). But if making changes on a object, saving it, and then revert
the changes (to the same state as before changing it the first time),
making changes on other objects is possible.
As mentioned in the WO API Reference, for pages being stored in a
variable the ensureAwakeInContext method has to be called, but this
has no effect. Same if refreshing the objects in the default editing
context (refreshAllObjects, refaultAllObjects) which is used on all
pages.
Any suggestions or other hints would be appreciated.
Regards
Andri

Re: Google Data Client Library (gdata) install with WebObjects
Thanks Chuck, I placed the gdata folder in the Libraries folder for the app and then added it via Configure Build Path in Eclipse. This seemed to make all imports happy and the app worked in development. When it didn't work in deployment I tried moving the gdata folder to a folder within System/Libray/Java/ and changing build path. Again devel happy deployment can't seem to find it. I also added various dependencies to the System/Libray/Java/Extensions folder on both devel and deployment computers. I assume Libraries are added at compile time and need not be moved to the deployment server so if it did not work in deployment the build was a problem. What problem and how to fix it is a mystery. Or maybe I have a bad assumption. Just in case I moved the gdata folder to the server too. I also made sure all extensions were the same on both computers. Sorry for the addressing problem. Anyones wisdom in this area would be greatly appreciated. On Oct 13, 2009, at 12:00 PM, Chuck Hill wrote: Hi Greg, Please keep messages on the list.

Re: Problem with pages saved in a variable
Hi!
Chuck is right, your completely screwing WebObjects up.
pageWithName returns you a component initialized for a given context
(WOContext, not EOEditingContext). If you are using the same pages for
different situations and mixing up sessions and stuff, NOTHING will
work. Nothing. Even if it APPEARS to work on your computer, it won't
on production with many users using the app simultaneously. I can't
even think about how many problems will it create, WO is simply not
supposed to work like that.
Also, WebObjects already caches a lot of stuff internally (if you
compare the time it takes to load a page generated by a given
component the first and subsequent times, you'll see this clearly), so
you don't need to hack in any more caches, you're probably making the
performance worse instead of improving it (and killing correctness, of
course).
Delete all that, and simply use pageWithName normally.
Yours

[MEETING] WO-Nova October 27, 2009
Greetings All, Because of a K12 party and several other conflicts, we are moving this month's WO-NoVA meeting to October 27 at the usual time and place. 6:30 PM and K12's offices K12 2300 Corporate Park Drive Herndon, VA 20171 http://maps.google.com/maps?f=qsource=s_qhl=engeocode=q=2300+Corporate+Park+Dr,+Herndon,+VA+20171sll=38.951406,-77.395933sspn=0.006642,0.008175ie=UTF8z=17iwloc=A Unless I am mistaken, Travis Britt will be leading a discussion of WO vs. Ruby on Rails as part of what we hope might be an ongoing series of discussion regarding the plusses and minuses of WO vs. any of the various theoretically competing technologies. As usual, K12 will be providing eats, and if so inclined any are welcome to continue the discussion afterwards at Ned's for a beer or two. Hope to see you there!

Re: Google Data Client Library (gdata) install with WebObjects
You are my hero! That worked great. They are all jar files, I copied them to the Libraries folder and deleted the gdata folder that was in there. Then in Eclipse I created a new library, added all the jars from that folder and added that library to the build path. Now it works in deployment too! A follow up question about System/Libray/Java/Extensions. I have put many jar files in there to do this or that thing with general success. (Though in this case the gdata instructions seemed to indicate I would need to add mail.jar. Once I did that, email seemed to fail.) By the emphasis below, it seems that may not be the correct practice. What would it be? Same as above? Another location? For all jars, or just some? Many thanks.

I think it is safe to say that you should never, ever, ever put anything in /System/Libray/Java/Extensions. Some things _can_ go in / Libray/Java/Extensions, but I would think really carefully about version dependancy problems before I did that. I confess that I often still put JDBC drivers there. The best place to put jar file dependancies is in Libraries in your app or in a re-usable framework as appropriate.

Re: Entity naming
For myself I keep the entity name and the class name the same and have them match the table name as much as possible including singular/ plural state. I find it keeps things easy to remember and reduces mistakes. I also prefix my entity names (and class names) with Db just because I like my names for classes to somewhat match their purpose. So, if I had a table named sites then I would have an entitiy name of DbSites and a class name (including package) of something like com.rhodes.eo.DbSites. That's just my style though. Everyone has their own. ;) On Oct 13, 2009, at 7:43 PM, Lon Varscsak wrote: If you have a table named sites what do you name your entity and the corresponding class?

Hudson and setupWorkspace.sh
I am trying to get a Hudson build server setup and I am having a few issues. Hopefully someone can/will help. As background I am running hudson on Mac OS X server and I am using subversion. 1) The setupWorkspace.sh script seems to be looking for the .classpath file in the wrong place. I setup the subversion URL as https://svnserver/path/MyProject. So when Hudson check out from subversion the .classpath is placed in $WORKSPACE/MyProject/.classpath, but setupWorkspace.sh is looking for $WORKSPACE/.classpath. What am I doing wrong? 2) The setupWorkspace.sh prints the following error even though I can go in by hand after the build and that directory does exit: rm: / Developer/Hudson/Home/jobs/MyProject/workspace/Root/System: No such file or directory 3) How will my apps and frameworks find the frameworks they depend on? Is this automatically done by the setupWorkspace.sh script as long as those frameworks have already been made? Do I have to do a build and install so that they are placed in /Library/Frameworks? 4) I can not get Hudson to Archive the Artifacts for framework builds when set to $WORKSPACE/MyProject/dist/*.framework. The configuration screen tells me that $WORKSPACE/MyProject/dist does exist but the build throws an error saying it can not find /Developer/ Hudson/Home/jobs/MyProject/workspace/MyProject/dist/*.framework. 5) Similar to #3. I have some frameworks that depend on jar projects. Do I need to somehow copy these to a location to be picked up or will the setupWorkspace fix it so that the jars will be found?

Antw: Re: Problem with pages saved in a variable
The code has been removed.
I read about caching pages using the same approach (more or less) on
this list
(http://lists.apple.com/archives/webobjects-dev/2003/Nov/msg00608.html).
I understand that WO is not supposed to work like that. But methods
like the WOComponents ensureAwakeInContext or
restorePageForContextID in WOSession made me feel like this could or
should work somehow.
Now the WO caching mechanism will be used (again).
Thanks for your guidance Chuck and Miguel.

Hi!
Chuck is right, your completely screwing WebObjects up.
pageWithName returns you a component initialized for a given context
(WOContext, not EOEditingContext). If you are using the same pages
for
different situations and mixing up sessions and stuff, NOTHING will
work. Nothing. Even if it APPEARS to work on your computer, it won't
on production with many users using the app simultaneously. I can't
even think about how many problems will it create, WO is simply not
supposed to work like that.
Also, WebObjects already caches a lot of stuff internally (if you
compare the time it takes to load a page generated by a given
component the first and subsequent times, you'll see this clearly),
so
you don't need to hack in any more caches, you're probably making the
performance worse instead of improving it (and killing correctness,
of
course).
Delete all that, and simply use pageWithName normally.
Yours

Dear List,
in an Applications Session, a NSMutableDictionary object is used
for
caching pages. Everytime the pageWithName method is called,
the
dictionary is queried in order to determine if the requested page
does
already exist, if true the existing page is returned, else a new
one is
generated and stored in the dictionary. This is made in
Application.java
by overriding the pageWithName method:
public WOComponent pageWithName(String aName, WOContext aContext)
{
Object result = null;
if ( aContext.hasSession() ) result =
((NSMutableDictionary)
((Session)aContext.session()).cachedPages()).objectForKey(aName);
if ( result == null ) {
result = super.pageWithName(aName, aContext);
if ( aContext.hasSession() ) if ( aName != null )
((NSMutableDictionary)
((Session)aContext.session()).cachedPages()).setObjectForKey(result,
aName);
}
return (WOComponent)result;
}
This works with one exception. Making changes on Enterprise Objects
is
not possible in every case. Saving changes works, if always the
same
object is changed but not if two different objects are changed
(changing
the first, saving the changes, then changing the second and saving
the
changes). But if making changes on a object, saving it, and then
revert
the changes (to the same state as before changing it the first
time),
making changes on other objects is possible.
As mentioned in the WO API Reference, for pages being stored in a
variable the ensureAwakeInContext method has to be called, but
this
has no effect. Same if refreshing the objects in the default
editing
context (refreshAllObjects, refaultAllObjects) which is used on
all
pages.
Any suggestions or other hints would be appreciated.

Andri
