EOModel and derived column.
I am reading the Red Webobject 5.0 book and I think I finally understand the small section on creating an attribute the is derived. (I am using postgresql as the backend) so my User entity has a firstName and a lastName. I created an attribute called 'theFullName' as derived "firstName || ' ' || lastName", in the advanced tab, I choose "Read Only". i assumed that would be enough, however I needed to also select 'allows null' in the basic tab. if I didn't, User.createUser(yada, yada); required a 'theFullName' attribute. My assumption was that as the column is derived and read only, I thought the column was special and shouldn't need the 'allows null' selection. so, did I do it correctly? as the column is a derived column and read only, why do I need to add 'allows null'? I have been creating all these derivatives in java in my User.java file, but I thought I would expand my understanding and play with some features. now on to stored proceedures.

otherclasspath option in maven?
I'm using maven to build a Wonder app and I need to have a resource file (a keystore) end up in a directory on the classpath at runtime. In the ant build I could use the "otherclasspath" option of woapplication to add a Resources/Keystores folder to the classpath. Is there something equivalent for maven? Or, is there a way to tell maven to include those files in the application jar? The "standard" way as described in the maven getting-started guide doesn't seem to work - the files are just included in Resources, but not in the jar. Thanks for any help.

Re: Database Connection Question
Hello all Thanks for you replies. Looks like I have enough to explore yet. > It should not be creating more unless you are creating more EOF stacks in you > code. The point is that I do use multiple EOF stacks. I clearly admit that each EOObjectStoreCoordinator gets its own set of db connections. I use separate EOF stack to access previous year data stored in a separate database with identical structure. That is why I employ EODatabaseContext.forceConnectionWithModel(model,connectionDict,ec) And that is why my models get identical connection dictionary. I am quite interested if multiple models could share single db context and thus lower the number of open connections. During my experimentations I have found that it is EODatabaseContext.forceConnectionWithModel(...) the one who create a connection for a mentioned model which does not get reused afterwards. May be that is aforementioned JDBCinfo connection? In my case I decided to close that AdaptorChannel myself after connecting model to database. As a result I have no dangling connections after launch. And when an app needs data for some real work it opens new connection that gets reused afterwards.

Re: Database Connection Question
Hi Guys; One per db context and no. My problem is that I see my app opening more connections than a number of models it has. Mike talked through a work-around for this bug to me recently on here. I had the same problem eating lots of connections into an Oracle database from the app-servers. If you are using "ERXJDBCAdaptor.java" then it should resolve this problem I think; otherwise I created my own "JDBCAdaptor" and copied in the methods "jdbcInfo()" and "typeInfo()" verbatim. This seems to have resolved the problem. cheers. -- Andrew Lindesay www.silvereye.co.nz ___ Do not post admin requests to the list. They will be ignored.

They all need to have the same connection dictionary. This allows one database schema to be partitioned between several models. I could be wrong too :-) All the models might be part of the same EODatabase, and each model gets its own EODatabaseConnection.

Re: ERRest and ToMany relationships
Maybe it's because of the way some methods are override in our framework. I was trying to get over the problem by creating the order first (POST /ra/commandes), and after to create the order item (POST /ra/commandeArticles). But the sales taxes on the order item were not calculed when they should be calculed automatically. The taxes calculation is done when we set the quantity of the order item (setEcoaQuantite) and this setter is override so that we check if a product is linked to the order item and if it's linked, we calculate the taxes amount. Problem is that when setEcoaQuantite is called, the relationship (produit()) is not set, so the condition (if produit() != null) fails and the calculation is not done. But I did specify the product ID in the JSON data, so I guess setEcoaQuantite() is called before setProduitRelationship(). If I call the calculation after the CommandeArticle object is created, everything's working. We have a lot of funked things like that in that framework, so it might explain the other problem (creating the order and items in a single call) I'm having. > seems like a bug > > On Nov 20, 2010, at 3:20 AM, Farrukh Ijaz wrote: > >> >> On 19, نومبر 2010, at 11:30 PM, Pascal Robert wrote: >> >>> Hi (especially Mike S.), >>> >>> Mike, in the comments you made on my ERRest slides for WOWODC, you said >>> that sub-entities should be created for To Many relationships, but I just >>> tried back and it's doesn't work for me.

Not sure, what you mean here, but the idea is to create a thumbnail

What's the full stack trace?

ERFileAttachment instead of ERAttachment.

So I have to create the thumb...
How can I manage the upload?
Now I override willUpdate and willInsert in ProductERAttachment entity.
@Override
public void willInsert() {
this.updateThumbnail();
super.willInsert();
}
@Override
public void willUpdate() {
this.updateThumbnail();
super.willUpdate();
}
private void updateThumbnail() {
ERImageProcessor.imageProcessor().thumbnail(40, 40, inputFile,
outputFile);
}
But... what about inputFile? How can I retrieve it from the ERAttachment object?

It doesn't fix the problem...This is strange... in a previous test (some days
ago) I did not have this error... just the form encryption exception...

Re: Wonder's Monitor
AFAIK, that tab was added when they tried to move away from wotaskd/Monitor to plain old Apache and NIO support, which was supposed to be in 5.4 (presentation at WWDC 2006 I think). True, the info on that page show how you can move to mod_proxy, but IMHO I think that should be explain in the wiki. Or we keep the tab in Monitor, we should explain what it is, right now, it's just a bunch of Apache directives. > How so? > > Cheers, Anjo > > Am 23.11.2010 um 00:48 schrieb Pascal Robert: > >> Ah, finally a Monitor for the 2010s :-) BTW, I think we should remove the >> Migrations tab, AFAIK that tab content is useless. >> >>> Looks like poo ;-) >>> >>> >>> >>> ;david >>> >>> -- >>> David LeBer >>> Codeferous Software >>> 'co-def-er-ous' adj.

WO 5.4 with IIS (In search of the lost ".dll")
Hello I have test the Deployment-Windows WO 5.3 - WO 5.4 :http://wiki.objectstyle.org/confluence/display/WO/Deployment-Windows+WO+5.3+-+WO+5.4 It's perfect. Thank you to Stefan Klein and Frédéric JECKER. But I want to use IIS then I have take the WebObjects.dll and the webObject.exe from WO 5.2. I have configure the HTTP Adaptor URL with http://server/scripts/WebObjects.dll When I launch my Application : http://server/scripts/WebObjects.dll/MyApp.woa ,it's Ok . I get the main page. But when I navigate to the next page have an error page, i get this URL http://server/scripts/WebObjects/MyApp.woa/1/wo/rKa7QJEtjTPy67V4o1IEVg/0.0.19.10.1.0.2.5.0.1.1.0 without the ".dll" after WebObjects.

Re: Database Connection Question
Hi,
you can use the following to check who is creating your channels:
public Application()
{
super();
...
// register for database channel needed notification
NSNotificationCenter.defaultCenter().addObserver(this,
new NSSelector("createAdditionalDatabaseChannel", new Class[] {
NSNotification.class }),
EODatabaseContext.DatabaseChannelNeededNotification, null);
...
}
public void createAdditionalDatabaseChannel(NSNotification notification)
{
EODatabaseContext dbContext = (EODatabaseContext)
notification.object();
if (dbContext != null)
{
EODatabaseChannel dbChannel = new EODatabaseChannel(dbContext);
// consensus is that if you need more than 30 open channels,
// you might want to re-think something in your code or model
NSLog.err.appendln("createAdditionalDatabaseChannel");
if (dbContext.registeredChannels().count() < 30)
{
EOAdaptorContext adaptorContext = dbContext.adaptorContext();
dbContext.registerChannel(dbChannel);
}
}
}

I think that EODatabaseContext is more correct than EODatabaseChannel. The
context will then use the channel. A db context can handle multiple models
(the connection information needs to be the same).
How can single db context handle multiple models ? I see that
EODatabaseContext.forceConnectionWithModel(model,cd,ec)
returns different objects for different models, whereas most of my
models point to the same database with the same connection dictionary.
And would it make sense to somehow force all these models to single db context?
Is there a default number of EODatabaseChannels opened when the app starts up?
Is there a configuration setting that I can set to add more?
One per db context and no.
My problem is that I see my app opening more connections than a number
of models it has.
And those connections do not close even after more than an hour not
used. And it does not reuse all of them for later requests but may
create even more connections.
As a result when running multiple instances on a server with limited
DB-connections I do get "too many connections" error sometimes.
How could I fight it? Is it possible to control the number of open
connections and close unused ones after certain idle time?
