Folder structure with Eclipse
Hi all, My WO project has grown in the last years and it is not structured to well, with packages etc. I'm coming from a Xcode project with lots of nested folders for WebComponents as well as for java files. Now i want a clear folder structure in Eclipse too. What is a clever "refactoring" for improving the project structure. It is also not very clear, how to put EOGenerator files in their own folder in the creation cycle (to keep the project folder content small). I used to have a folders "EO's" and "Generated EO's" where i never needed to look into the "Generated..." folder for obvious reasons :-) Is there a how to on the web or will someone talk about his solution?

Hi list, Sorry for ignoring the tons of mails that have been spend on this and similar subjects since WWDC 2006 (i've read some of them, but the threads got longer and longer..., and less interesting [sorry]). I can see clearly that the community has to engage itself and i want to do my part and offer the following: 1. I will support the website with my Xserve for free (10.4.7, mySQL optional Frontbase, Mail..., still many gigs available) 2. I will give 2 or more dedicated admins of this project full admin access to this server 3. If someone knows how to, set up a mailing list for our special interest group (Off of apples lists) for internal communication 4. I will pay the transfer volume Someone else should please get a domain (please stop discussing on this minor problem, simply get all of the discussed domain names:-) ) and care for routing to my server. I expect that we are setting up a interest group that will structure the content of the website, others defining the layout and corporate design etc., a lot of them hacking I expect that we will have a highend "web 2.0" webobjects website who's sourcecode is free and downloadable from this site. We should make it even more easy for WO interested developers to get started. Because i'm very busy in the moment, let me hear clearly if we will follow this way, so i can arange to follow the regarding threads on this list and do my part for it. I have been developing for 1.5 years a realy nice web application (www.webclubs.de) and i have been supported perfectly by this list.

Yes, I had a big problem a while ago NOT having some reverse relations, so i
always have reverse relations. It is absolutely unclear in which case they

This seems to be a reasonable reason. I should have found this myself by
creating setters and overrides for addObject...
But i think it is both error prone, either forgetting to write the component
method, or using the set-Method instead of addObj... in the factory method.
One thing helps: always be aware of this pitfall.

Relation oddity
Hi list, i have a huge data modell and allways use factory methods to create and init EO's. I'm using the defaultEditingContext. In some of the factory methods i assign a Division "d" to a (n:1) relation by the setter (Division is a derived class in a vertical inheritance). "d" is taken from person.defaultDivision, a parameter to the factory method. theEvent.setDivision ( d ); When i edit theEvent in a page, I'm able to set theEvent to another divisione from a popup listbox. The Listbox is bound to a list from a session EO, i.e. client.divisions. The data is saved correctly to the database. When i change the factory method to use theEvent.addObjectToBothSidesOfRelationshipWithKey ( d, "division" ); and continue doing the same (change the division via popup listbox), on the first save the wrong division is saved. I can see that the wrong fk is written. Tracing the values of the division in the save cycle shows the correct value before **and** after the saveChanges. When i open theEvent again and change the list value and save again, the fk is saved to the correct value. Anybody seen this?

Now it works like a charme.

And after all this good tips, you might think about factory methods for each
class like this:
public static MyClass newMyClassForYourRelatedEOs ( EOEditingContext ec,
MultipleParameter myRelatedEOs )
{
MyClass newObject = new MyClass ( ec );
// set your initial relationships
newObject.addObjectToBothSidesOfRelationshipWithKey ( myRelatedEO1,
"myRelation1" );
newObject.addObjectToBothSidesOfRelationshipWithKey ( myRelatedEO2,
"myRelation2" );
//
return newObject;
}
The final setup can follow here:
public void awakeFromInsertion ( EOEditingContext ec )
{
super.awakeFromInsertion ( ec );
// set your initial values
}
Validating might be a nice idea too:
public void validateForSave () throws NSValidation.ValidationException
{
// do your validation first (i prefer this, because super.validateForSave
returns always english error messages, so i try to validate before super and
display my own colloquial)
super.validateForSave ();
// or do your validation last for all remaining errors
}

cant analyse illegalstateexception
Hi List,
i have a problem to analyse the following error:
java.lang.IllegalStateException: A valid global ID could not be obtained for
entity named Class_Hour, relationship named location_Rooms, primary key
dictionary {fk_location_room = 5; fk_class = 26; }

Code in deleteClass:

ec.saveChanges ();
The entities are:

Delete Rule: casc-> null <-casc
null
"fk_location_room" and "fk_class" from the error primary key dictionary are
both in "ClassHour".
The relation "location_Rooms" from the error message is from "Class" to
"Class_Hours.location_Room", "Class_Hours" is from "Class" to "ClassHours"
When i delete a "Class" with a "ClassHour" assigned, that points to a
"Location" and a "location_Room" i get the above mentioned error. (A
"location_Room" can only be assigned when a "Location" is assigned before.)
Any ideas for a solution?

I intended to create requests and execute them.
But i dont know how...
pseudo code:
r = new WORequest
r.setDAParam (a)
r. perform
or the like...

- Most important to test that programm changes simply have the same result
afterwards
- Second to test variants of calls
- Third to test correct parameter supply
- Fourth to simplify testing of a set of DirectActions
- Fifth to test the robustnes of DA's to wrong input (When someone creates
it's DA-calls manually)
Am i wrong?

WOUnitTest for relations
Hi again,
i try to create an object hierarchy in the test editing context.
the factory methods below set up the relations as required.
then i delete the root object from the ec. I want to see, that the delete
rule "cascade" realy does a cascaded delete!
i thought, i could test the remaining content like shown below in method
assertEditingContextRemovedInserted.
After creation there are 3 objects in ec.insertedObjects.
After deletion of "aPerson" there are 2 still objects in ec.insertedObjects.
This means, cascaded deletes are applied not earlier than on saveChanges?
How could i test the cascaded delete correct?
TIA
Wolfram
--
Code sample that creates the hierarchy:
...
EOEditingContext ec = this.editingContext (); // from WOUTTestCase
CMandant m = CMandant.getMandantForAlias ( this.editingContext (),
NSProperties.getProperty ( "DefaultMandant", "pappnase" ) );
CPerson c = ( CPerson ) m.creator();
CPerson aPerson = CPerson.newPersonForMandantAndPerson ( ec, m, c );
CAddress theAddress =
CAddress.newAddressForMandantAndBusinesPartnerAndPerson ( ec, m, aPerson, c
);
CTelecom theTelecom =
CTelecom.newTelecomForMandantAndBusinesPartnerAndPerson ( ec, m, aPerson, c
);
// ec.saveChanges ();
ec.deleteObject ( aPerson );
// ec.saveChanges ();
// all objects should be deleted via delete rule
this.assertEditingContextRemovedInserted ();
...
public void assertEditingContextRemovedInserted ()
{
// test if content is unchanged, i.e. added eos and removed eos
->unchanged
NSSet inserted = new NSSet ( editingContext().insertedObjects () );
NSSet deleted = new NSSet ( editingContext().deletedObjects () );
NSSet remaining = inserted.setBySubtractingSet ( deleted );
try
{
assertTrue ( remaining.count () == 0 );
}

{

But let me try to explain a little different. Always when you are aware of masses of data, you should never expect automatisms to be the perfect solution. This sounds a little of wrong planning. If you know you have masses of data, there should be some very extraordinary reason to fetch them all at once, automatically or not. I can't find a reason, while writing this :-) you wouldn't create a report via EO this way, would you? Based on your knowledge of quantities start planning another way. Try to segment your data on secondary attributes so that you never have tons of data. I would recommend to use custom fetch specifications for this always, based on primary criteria and restrictions from user input. The user should be the limiting "entity" here. The user is never able to review millions of datasets, nor to read a report of this size... As you can see, i have no fast solution for you... But THINK!

EOKeyValueQualifier not resolving vertical inheritance?
Hi List, i create a complex query from user input via EOKeyValueQualifier and other EOQualifiers. Absolutely fine is: EOKeyValueQualifier ( myAttributeName, mySelector, myComparedEO ); Also OK is it for a keypath to a non flattened attribute (lets say: "location.derivedClassAttribute", where location is a derived class): EOKeyValueQualifier ( "location.derivedClassAttribute", mySelector, myComparedValue ); (myComparedValue is a string in this case). The above statement creates joins with aliases like: ...FetchedClass t0, Location T1, LocationBaseClass T2... and fetches the correct EOs. When the left hand side points to an attribute of an inherited class it evaluates to the wrong derived entity: Compared to the above example: EOKeyValueQualifier ( "location.baseClassAttribute", mySelector, myComparedValue ); does not evaluate to table "Location". Instead it creates aliases like: ... FetchedClass t0, Person T1, LocationBaseClass T2... where "Person" is another derived class of the same base class. This seems to be a bug, because the class information for "location.baseClassAttribute" is available and correct for the relation "location", but it does not create the correct SQL.

Thats what i do (it's not simply java but...):
class Thumber extends Thread
{
private String source;
private String target;
public Thumber ( String aSource, String aTarget )
{
source = aSource;
target = aTarget;
}
public void run()
{
try
{
String command = "sips -Z 400 -s format jpeg -s
formatOptions low " + source + " --out " + target;
if ( NSLog.debugLoggingAllowedForLevel (
NSLog.DebugLevelDetailed ) )
{
NSLog.out.appendln ( "Thumbing command : " + command );
}
Process p = Runtime.getRuntime ().exec ( command );
if ( NSLog.debugLoggingAllowedForLevel (
NSLog.DebugLevelDetailed ) )
{
NSLog.out.appendln ( "Thumbing process waiting " );
}
new StreamGobbler ( p.getInputStream(), "Thumb-process
INPUT" ).start();
new StreamGobbler ( p.getErrorStream(), "Thumb-process
ERROR" ).start();
int terminated = p.waitFor ();
if ( NSLog.debugLoggingAllowedForLevel (
NSLog.DebugLevelDetailed ) )
{
NSLog.out.appendln ( "Thumbing result: terminated (0=OK)
: " + terminated );
BufferedReader in = new BufferedReader( new
InputStreamReader ( p.getErrorStream () ) );
NSLog.out.appendln ( "Thumbing error : " + in.readLine
() );
}
}
catch ( Exception e )
{
if ( NSLog.debugLoggingAllowedForLevel (
NSLog.DebugLevelDetailed ) )
{
// quiet error
NSLog.err.appendln ( "Error creating thumb file : " + e
);
e.printStackTrace();
}
}
}
}
"sips" is included in mac os x. As a result i have the uploaded file and for
display purpose i use the thumbed file.
As an automatism i try to show thumbed files first, taking the original if
no thumb exists. This will help also for cases where no thumb could be
created... as for Word-Documents :-)
You may set the target resolution and size as you need.
I tried ThumbsUp in the same manner as above with varying results...

How many E-mails maximum?
Hi List, my WO-Application is able to send mails to an unrestricted amount of persons. It is not spamming i intent, but sometimes there are huge amounts of mails requested... :-) What is your experience how many mail recipients will pass through the layers (java.mail, mail server)? I have Odaiko mail framework from the net. It creates a vector of recipients from a huge NSArray created from my data and does it's magic passing this to java.mail. I wonder if it would be more clever to send huge amounts of mails in bundles of, lets say 100, recipients to prevent failures and rejection by "who knows". I modified Odaiko mail so that it uses flexible intervals sending mails to prevent rejection of bulk mails, but this would not help with one mail to 1-3000 recipients, i think.

ChangeNotification from dneumann
Hi List, once (when i was young :-) ) i picked up the ChangeNotification framework from dneumann (ChangeCathcer.java created by dneumann on Wed 21-Apr-1999 etc.) It is not pure WebObjects, it uses also some other classes like com.apple.cocoa.foundation.NSObject. Thats the easy case in porting it. Has anybody replaced the code for NSArchiver and NSUnarchiver successfully? The NSArchiver part i fixed by including import com.apple.cocoa.foundation.NSArchiver; import com.apple.cocoa.foundation.NSObject; import com.apple.cocoa.foundation.NSData; It compiles well then. Is this working later on, not on a sun or windows machine, but on a mac? But there is a dirty and not compiling part: com.apple.cocoa.foundation.NSDictionary dict = (com.apple.cocoa.foundation.NSDictionary)NSUnarchiver.unarchiveObjectWithDat a(( com.apple.cocoa.foundation.NSData ) ( request().content() )); which leads to a "inconvertible types" for the result of content () wich in fact is a NSData, but from com.webobjects.foundation.

File upload as longresponse page
Hi list, is there any known implementation for a file upload with a long reponse page, giving feedback for the upload process? The reason i ask (and correct me when i'm wrong!): - browsers do not check the file size - browsers will time out in normal WOFileUpload on files to big - Sessions might time out, when the normal WOFileUpload takes tooo long :-) - Users get bored, uploading large files, getting told "file to big". Before WO included WOFileUpload component, there must have been lots of implementations for streaming. Would it help, doing it myself? Any code snippets? And (sorry for asking, might be very dumb :-) ) would i be able to check the file size before streaming up, i.e. to provide progress information? Thanks all!

I followed your recommendations regarding the implementation of the MyType class (immutable etc.). Further i implemented a formatter "MyTypeFormatter" which i use for data exchange in my component. Works like a charme!!! One question remains: I allocate the formatter as a public final member in my application at the moment. Is it a reasonable place or should i allocate it in session or component context? I would say, session is best for speed, resources and safety, do you agree? Thanks Wolfram P.S. In a short while i will publish my "BaseWOApp" with several interesting solutions (MyType EO data type, timertask for property update [from PropDemo.zip, www.bugs-and-errors.de], page member pushing and popping for correct forward and backward navigation, standard error handling pages...)

Custom type EOModeler issue
Hi list,
Nice christmas? Hopefully.
As a training session i created a custom data type " MyType":
I created my own class MyType with the recommended methods (see below).
In EOModeler i map MyType to:
External type: varchar
Type: Custom
Width: 3
class: MyType
factory method: valueOf: (see below!)
conversion method: toString ( see below!)
Init Arguments: NSString
Getting values from the DB works like a charme.
Save.Changes leads to:
java.lang.IllegalArgumentException: While trying to invoke the set method
"public void CSampleTable.setAvalue(MyType)" on an object of type
CSampleTable we received an argument of type java.lang.String. This often
happens if you forget to use a formatter.

I tried to follow "Practical WebObjects" but without success!
What am i missing?
It seems to me, that one or more additional methods are required, to convert
objects correctly for this purpose.
In comparison: i have the sample Boolean class of Practical WO, it works!
TIA
Wolfram
public class MyType {
private String value;
public MyType ( String v )
{
this.setValue ( v );
}
public void setValue ( String v )
{
value = v;
}
public String getValue ()
{
return value;
}
public static MyType valueOf ( String v )
{
return new MyType ( v );
}
public String toString ()
{
return value;
}
public Object clone () throws CloneNotSupportedException

}
public boolean equals ( Object obj )

Yeah, Art's idea with > class=LocalizationCodePage.MyDisplayGroup is not bad, but i dont think that WO can resolve anonymous classes (it can not deal with static methods, so that makes me cautious). try it with a MyDisplayGroup in it's own class file. then try again with: class=MyDisplayGroup Let me hear if it helps! regards Wolfram ___ Do not post admin requests to the list.

Hi Owen,
this is a part of code from a component, where i buffer some values of the
component in the session:
// return parameters for BAETable
// + personBatch.numberOfObjectsPerBatch
public int selectedPage;
public boolean initialSortAscending = true;
public String initialSortKey = "name";
public NSMutableDictionary getReturnParameters ()
{
NSMutableDictionary result = new NSMutableDictionary ();
result.takeValueForKey ( this.getNumberOfObjectsPerBatch (),
"numberOfObjectsPerBatch" );
result.takeValueForKey ( Boolean.valueOf ( initialSortAscending ),
"initialSortAscending" );
result.takeValueForKey ( initialSortKey, "initialSortKey" );
result.takeValueForKey ( new Integer ( selectedPage ),
"selectedPage" );
return result;
}
As you can see, the primitives are stored via the wrapper classes in a dict
too.
This is the method in session, that pops the values from a "stack" and sets
the values in any of my components.
public void popReturnParameters ( String theCalledPage, WOComponent
nextPage ) throws NSValidation.ValidationException
{
NSMutableDictionary result = ( NSMutableDictionary )
returnParameters.valueForKey ( theCalledPage );
if ( result == null )
{
// return parameters have not been pushed
// could log
return;
}
returnParameters.removeObjectForKey ( theCalledPage );
NSArray allKeys = result.allKeys ();
for ( int i = 0; i < allKeys.count (); i++ )
{
String key = ( String ) allKeys.objectAtIndex ( i );
nextPage.takeValueForKey ( result.objectForKey ( key ), key );
}
}
The values from the wrapper classes are restored perfectly into the
primitives.
I think, thats exactly what you described as not working, but it works
great!

Indeed, but keep in mind: every running instance will keep it's own lists. On the other hand, if the tables do not depend on a users preferences (i.e. language) keep them in the application, that's sufficient! Oh: one thing more, fetch those tables via the same EOEditingContext as the one you use for other entities you want to relate to this values! Otherwise you will get error messages on saving.

Try doing super.appendToResponse last!

aResponse.setHeader ("application/csv", "content-type");
aResponse.setHeader ("filename=excel_file.csv", "content-disposition");
super.appendToResponse(aResponse, aContext);

Hello all,
for all of you not reading german too good:
Ute recommended to use JSConfirmPanel from Javascript Palette.
Best tip for a long time :-)
Enclosed you can find a component that i use on all places where i want to
have a confirmation on a submit.
The component has three bindings:
1. the action to invoke on confirm
2. the message to display for confirmation
3. a flag, if confirmation is necessary (i bind it usually to a flag of the
users settings (yes, please confirm all deletes))
For useage i embed a button inside the Component and bind the action of the
button to the components action.
Realy easy, you all will understand :-)
One pitfall: not all browser display the component absolutely perfect, some
might show an underline above or beside the button (as i use it) because it
is in fact a hyperlink.
So far i used it only for confirmation of deletes and probably the hyperlink
will not result in a full RR-loop, so it will not work for data updates, i
expect...

P.S. I don't need to do all this javascript stuff to transfer values myself,

depending on the return value on the client side i need either the

Sounds easy.. but i'm missing the details.

WO and Javascript
Hi list,
after searching and testing a lot, i finaly have to ask:
I have normal WOComponents using submit buttons for saving data etc.
I want to validate via javascript that the user is sure to DELETE data.
For this i created a javascript funtion that is bound to a delete buttons
"onclick".
So far OK. But now i need the value of the confirm ( "are you sure?" )
inside my WOComponent.
I tried several thousand permutations of bindings, code etc.
At the moment i have a variable "confirmed" in my component.
I bound it to a hidden WOTextField with ID "confirmed" and try to get the
value with
aVar = this.document.Form1.getElementID("confirmed").value;
where Form1 is a binding "name" i attached to my WOForm.
It does not seem to execute this code correct, i do not reach another alert
("did it") after this code.
At last i wont to return the value with:
if ( check )
this.document.Form1.getElementById("confirmed").value = "true";
else
this.document.Form1.getElementById("confirmed").value = "false";
which doesnt work either.
I expected the binding "confirmed" to be synchronized on the way back to the
server.
Any straight receipes how to return values from javascripts into a
component?
One thing i found searching the web is, that Chuck has a chapter on

So check first if the component is nested in another component, where another form wraps the sub-component.

Do something like this:
public void appendToResponse ( WOResponse aResponse, WOContext aContext
)
{
personBatch.queryBindings().takeValueForKey ( myBinding,
"myAttribute" );
personBatch.qualifyDataSource ();
super.appendToResponse ( aResponse, aContext );
}
The WODisplayGroup should have a FetchSpec correctly set.

As you will see, there are "MyTopic" entries below, where i dont know if
they are correct.

Right, thats what i thought it would do.
But what about:
See below, search for and you will meet the problem-points!
As one more problem, there are failures in the demo files. See below under
"startjms.sh".
Thanks for your help

Hi David,
Thanks for your hints.
1. The reason why i do this is, that i hopefully will have a site with high
traffic in the future, where i will need load balancing.
But thats a minor reason!
2. I have 3 Applications working on the same database, i.e. they might
change the same data entries concurrently.
One of the applications is an administrators app, two others are customers
applications. The admin might change some values, that are very important
for the customers, i.e. client aliases, which are also used for directory
locations. When those change, the customer needs direct feedback of the
change.
3. I asked on this list how to handle this issue, and i was told to do what
i'm now implementing.
So, what other tips do you have?
TIA

Data inconsistency between WOApps
Hi List, i have two WOApps running on the same server. They access the same data base. One is the user application, the other is a admin application. When i change essential data in the admin application and do a saveChanges() on this data, it is not updated in the user application and the userapp tries to access data under the old value (a directory name). I restarted the user application, and everything is fine, but i can't restart the user application after each change of a dataset :-) What is the reason: - a time gap? - do i need a refresh of the data in the user app? - any other (which) reason?

url issue on deployed WOApp
Hi list, i have one WOApp running under, lets say "http://www.a.de/";, which i drive on my xserve with a setup of the site: domain name = "www.a.de" ip="my.very.own.ip" port=80 w/o any special settings like aliases etc.. When i use the App it changes to something like "http://my.very.own.ip/cgi-bin/WebObjects/myFantasticApp..."; Thats, i think, because of the "index.html", where i have a redirect to: http://my.very.own.ip/cgi-bin/WebObjects/myFantasticApp";> I created a redirection at a providers place, lets say the url is "http://www.b.de/";, that redirects to "http://www.a.de/";. When i use the App starting it via the redirect url, it keeps always the "www.b.de" in the url of the browser, and i cant understand why. I would like to have my "www.a.de" behave the same, so someone of you might enlight me, what the difference is between the handling of those two urls by the webserver. Probably it has to do something with rewrite rules or something similar...
