Java Client (topic of the day!)
I could not be more agree that JC is the best kept secret in WO.

clearing a toMany relationship fault in Java Client
So far so good I tested
ERXEOControlUtilities.clearSnapshotForRelationshipNamed it works ok...
But for the server side only.
I´ve problems in a Java Client since in the server I´ve the correct
toManyRelationship NSArray data (i.e., refreshed) , but in the client
side I´m still having the old cache NSArray data from the relationship.
Any idea what I need to do?

This is something that really should get done as part of a refreshing
fetch. I think bugs have been filed on this, but another voice
increases the priority.
Was there some other place you were thinking of having this called
automatically? It might be useful to add a refresh() method to
ERXGenericRecord that would refresh the snapshot and all to-many()
relationships. But then... what about the related objects? How far
do you go?

Okay, so there's
ERXEOControlUtilities.clearSnapshotForRelationshipNamed[InDatabase]
(which saves me a few lines of code :) but which doesn't appear to

a property that does something like this automatically?
What I've now got in my ERXGenericRecord subclass now is:
public void awakeFromFetch( EOEditingContext editingContext )
{
super.awakeFromFetch( editingContext );
if ( editingContext ==
EOSharedEditingContext.defaultSharedEditingContext()
&&
ISHApplication
.ishApplication
().hasFetchedInitialSharedRecordsForEntity( entityName() ) )
{
for ( Enumeration< ? > en =
classDescription().toOneRelationshipKeys().objectEnumerator();
en.hasMoreElements(); )
{
String key = en.nextElement().toString();
EORelationship inverseRelationship =
entity().relationshipNamed( key ).inverseRelationship();
if ( inverseRelationship != null &&
inverseRelationship.isToMany() )
{
EOEnterpriseObject eo = (
EOEnterpriseObject )valueForKey( key );
if ( eo != null )
// this next line covers Anjo's
code from the wiki page below
ERXEOControlUtilities.clearSnapshotForRelationshipNamed( eo,
inverseRelationship.name() );
}
}
}
}
This is working fine. Is there any suggestions on anything else that
might need doing for completeness?

that they are refreshed.
Any suggestions?

The "Mobile me" web apps
I use them a lot to do all binding and here are some comment: - They´re good and elegant solution. - We use them since NeXTStep, so we are custom to use to them. Also it is mature and proven technology. - Subclass EOAssociation and include other swing components (e.g., JXDatePicker from SwingLabs) is easy. - They are bi-directional. - To create and have different aspects you can do many things, not just 'action' and 'enable' aspects. I don´t know in detail Florijan framework, but so far, I believe Florijan gets the same functionality but with a complete different approach. Let´s wait what Florijan has to say. Ricardo.

Sybase character set problem
We are in the process to migrate a very old WO 4.5 system using Sybase. The Sybase server has as character set "cp850" and in the old EOModel WO 4.5 we added the databaseEncoding = "NEXTSTEP" instruction in the adaptor info. Everything worked fine. Now we use WO 5.4 and JDBC (Sybase JConnect version 6.0) and nothing appear to display the non english characters correctly (e.g, á,é,í,ó,ú, ñ, etc) . I tried the CHARSET parameter in the JDBC URL(.e.g, jdbc:sybase:Tds:/? CHARSET=cp850&JCONNECT_VERSION=6) and many other options, none worked correctly Does anybody had the same problem before?

Fwd: Why I hate Java Client (I hope this could help you)
Helo Dave: Yes and no. What I´m meant is that I could move them but without using the rule machine. This is how: - 1st: All my D2JC screens using the Assistant (in WO 5.3) I freezed them in a XML file. The ones that already have been freezed, no modification was done. - 2d: I develop a class called MyControllerFactory that work similar as the EOControllerFactory class but without calling the rule machine. This is how it works: + This class (in the client side) calls the server to get the XML file of the WOComponent that I want to show. + With the XML file, the MyControllerFactory class parse it and instantiated the D2J classes (EOFormController, EOListController, EOTextFieldController, etc.) programatically (see the JCEntityViewer example if you need more detail). - 3rd: Show the root controller as a Window or Modal screen. So far it worked ok, but I have not tested with all D2J classes. note: I have to develop some minor additions: (a) Need to subclass the EOFormController and EOListController to catch the defaultActions() method in order NOT to go to the ruler machine and return the NSArray of EOActions statically. (b) With these two subclasses I have to override some methods (i.e., OpenWithTask, InsertWithTask and insert) in order to do the actual operation without the rule machine. Result: All the D2J screens keep the same. What I throw away was the rule machine (too complicate and time consuming for me to simulate its operation). The migration for existing D2J system was not so hard since we did not use the rule machine very much. The rule machine some how gave you the screen flow between D2J screens; this flow you have to re-code and you could do it in many ways (i.e., in the client (e.g, I add extra tag in the EOFormController called 'nextTask') or in the server). I hope these ideas could help you. Ricardo.

Re: Why I hate Java Client
I´m 100% agree with Florrijan. I´m using JC a lot, and sometimes it is much better solution for intranet, than Flex/Hibernate or other intranet platforms that I worked with (I´m not trying to open a discussion of what solution is better, what I´m trying to point out is that JC is very good). If you use the Florrrijan binding framework with JFormDesigner tool, or develop your own binding framework (as I did). You can develop screens very fast. More to JC in my case for simple screen I´m still using the D2JC controllers classes programatically with WO 5.4.1 Another happy developer using JC. Ricardo.

Wetter III" <[EMAIL PROTECTED]> Cc: Development WebObjects Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; charset=US-ASCII; delsp=yes; format=flowed So this is some sort of config problem, brought on somehow by the fact that I've moved all the .jar cruft we had hanging out in / Library/Java/Extensions into a framework. It looks like the server is forwarding some sort of EOGeneralAdaptorException to the client which might have had useful information in it but client has no idea how to unarchive it because for some reason it can't access eocasses, so it then throws a completely different exception on the client side. Interesting situation. The eoaccess package is not provided because it contains stuff that is irrelevant to the client. Mostly the "connect to database" stuff. So it makes sense it is not there. Like Lachlan says, log the exception on the server. Plus none of this stuff works for me from Eclipse, because no one ever got around to porting it fully to Eclipse when they moved the rest of the projects over. Meanwhile, the Support folks are whining, because I lowered the boom and told them Java Client was going away, Very much not true. Let the light of the JC sun shine on you and realize: Apple is not dropping it! YAY! :) so they have to adjust to an app that isn't just a thin coat of paint over Direct2JavaClient and actually come up with a specification for what all they use this piece of shit for. I've spent 40 hours over the last 2 weeks fighting with this stupid thing. It takes me about an hour to build a screen in the new app that will replace this crap. The new app being based on which technology? Might I suggest switching to WO Java Client "the third way"? No D2JC, no Interface Builder to Swing translation... It will still be possible to get exception stack traces that are somewhat obscure (until you get used to it at least, and apparently especially so if the root of the problem is a thrown EOGeneralAdapterExeption), but they will be shorter :) Best regards, Flor of The Perpetually Happy WOJC Lobby :) or simply TPHWOJCL p.s. - before you ditch JC as a lost cause, well, I've invested a _lot_ of time looking for a good rich GUI client - server tech that we could use in my company.

Re: [ANN] building JavaClient without nib but using swing gui with eclipse+wolips
Hi David, I have a D2JC project that I 'more less' migrate to WO 5.4 with the following considerations that I hope it will help you: - Even if you have all classes in WO 5.4, some are very difficult to migrate (e.g., EOControllerFactory, Rules, etc). So my decision was not to use the rules and any other related class. - I re-programed the rules behavior in the Client side (application specific behavior). What I want to do in the future is instead to use the rule machine is to use a simple BPM Java framework to handle all screen workflow. - What it still exists is the EOController class and its subclasses. So you still can generate dynamic windows. So in the Client side I called the server for the JC WOComponent template. I parse this XML descriptor and generate the EOControllers programatically (see EntityView example) like the EOControllerFactory in WO 5.3 actually does. I have not testes fully yet, but so far it is working. This keeps your JC WOComponents intact. What I found impossible to migrate is al the Assistant work (e.g., user.d2wrules file) so I plan to use D2W instead for this simple screens. I hope this will help you. Ricardo. . Hi David, I do'nt know.

Event firing from changing EOs
Dear Flor. The getter and setter methods are ok, but it think there is a better way. This is how the EOAssociation (and its subclasses) works. They are bidirectional: From the widget to the EODisplayGroup the EOAssociation class, I believe they are listener (analyzing the code generated by the old nib files in the EOArchive class), but from the EO to the the widget I believe the EOAssociation uses the EODisplayGroup class. The EOAssociations does not need to sublcass the EO. Why not use EOAssociations and EODisplayGroup? Ricardo. *** Thanks for the reply. I do not need this for logging. Where I need it in are Java Client applications. I am just finishing up a library that will make it quite easy to build WO + Swing applications. The library is totally event driven, all the GUI controllers and all that stuff has been made to respond to events fired by EOs that have changed. So, the end purpose is keeping the GUI in synch with the current state of EOs. So, if the changes in the end get saved to the database or not is not relevant in my scenario. That being said, what do you think? Till now my solution was to use EOGenerator to define setters that take care of event firing, when needed. This works, but I always wanted to do this more elegantly, and overriding the mentioned methods seems just about right. I am just wondering if EOF can at any time for any reason bypass them. Reading the API makes me think it can not, but I wanted to check...

It is imperative that the event firing is absolute, nothing can be allowed to slip by, if a property changes in any way, an event has to be fired. Hmm. Do you want to log the change in the EO or the change in the database? Because if you log changes to the EO, you might end up with logged stuff that was never saved and therfor does not exist outside the scope of where the change happened (and was reverted). What I did for logging changes to EOs was checkin in "willUpdate" (using Wonder) by getting the changes from the snapshot. I also have some code to check whether relationships change but that is not really thought out completely. cug -- http://www.event-s.net ___ Do not post admin requests to the list.

Making example WO apps
I do not speak for everybody, but in my case and I think almost all WO developers using JC and looking for the WO + String databinding, we came from WO 5.3. So we have Openbase installed with the example DBs. If you use the WORealState DB (or any other in the example) is fine.

So, I am wondering which database to use... At first I thought of making a simple database schema, but as I remember WO ships with some example databases, which are already populated and ready to be used. I've never worked on anything like this, so I have a few questions: 1. Which of the example databases to use? I am looking for something simple, a few tables, a few relationships, various types of attributes, but nothing much. 2. How is 5.4 regarding that? Does it ship with the example databases? I've read something in the documentation saying that OpenBase is not included anymore with WO, and IIRC all the example databases in 5.3 and earlier were in OpenBase... 3. Has anyone done this? Trying to make an example run-on-everything WO app seems impossible (especially if 5.4 does not come with pre- installed dbs, regardless of the vendor), and I really would like to make it easy for people new to WO/WOLips/Eclipse/SQL... 4. If 5.4 make this somehow possible, but in a way that is different then in 5.3, would somebody be willing to port the server app (the client code should be functional on both versions)? Any advice is welcome. Thanks, F -- ___ Do not post admin requests to the list. They will be ignored.

EOModeler: Migration from XCode to WOLips and WO 5.4
I had a JC app in WO 5.3 (and XCode) with a class like: businesslogic.common.user with two sublcasses: businesslogic.client.user businesslogic.server.user The class businesslogic.common.user has all attributes common to the client and the server (i.e., name, e-mail address, etc.). The class businesslogic.client.user has all attributes just for the client (i.e., none for my app). The class businesslogic.server.user has all attributes just for the server (i.e., password). When I tried to migrate to WOLips there is nothing in the EOModeler where I can define the client class and the server class. In the deprecated Apple develop tool EOModeler I could differentiate both classes and the instantiation will be done as expected for the EOEditingContext in the client side and EOEditingContext in the server side (I suppose that work was done by EODistribution class) Any idea how can I solved this problem using WOLips?

Java Client nib based Apps and WO 5.4
We developed a system using DTJ and Java Client nib based apps. Now that these technologies does not exists anymore in WO 5.4, after the frustration period, I need to keep going: switch to eclipse and wolips is a must, and also forget about DTJ (many easy catalog based apps were done this way). My problem is what to use instead Java Client nib based apps. I heard someone are using JFormDesginer or other tool. ¿Any ideas? If somebody has been working with swing GUI editor with WO using EODistributor I have these questions: - How do you solve the EOAssociation paradigm, do you developed you own EOAssociation (and all its subclasses). - How do you solve the EOInterace (EODisplayGroup, EOInterfaceController, etc) paradigm. - Do I have to solve these issues programmatically (low level programming for me), or there is any other better solution out there. Any idea will be very help full. Thanks, Ricardo. ___ Do not post admin requests to the list. They will be ignored.
