New convention of install path
Hi, Since Xcode 4.3 is released as a single app, it will suggest to delete the /Developer at first launch. It seems that Apple is trying to eliminate the necessity of /Developer in the future. If you're just like me, blindly trust the instruction without thinking, it's likely that you will delete the whole eclipse and webobjects stuff accidentally. (Hint: you'll also lose some handy tools like Pixie, QuartzDebug, Quartz Composer and Dashcode.) I was wondering if it's necessary to change the best practice of install and setup wo/wonder/eclipse inside /Developer directory. How do you think?

Re: Embed a external command-line tool in bundle
My Cocoa bundle is included in the FileSet specified by woproject/resources.include.patternset. The problem is how the woapplication task handle it. According to wiki, http://wiki.objectstyle.org/confluence/display/WOL/WOProject-Localization Not localized resource should be copied to the resources directory preserving subdirectories structure. But the following is my ant -v output: [woapplication] Resources/MyTool.app/Contents/Info.plist added as Info.plist doesn't exist. [woapplication] Resources/MyTool.app/Contents/MacOS/MyTool added as MyTool.app/Contents/MacOS/MyTool doesn't exist. [woapplication] Resources/MyTool.app/Contents/PkgInfo added as MyTool.app/Contents/PkgInfo doesn't exist. [woapplication] Resources/MyTool.app/Contents/Resources/MyTool.tif added as MyTool.app/Contents/Resources/MyTool.tif doesn't exist. [woapplication] Resources/MyTool.app/Contents/Resources/en.lproj/InfoPlist.strings added as en.lproj/InfoPlist.strings doesn't exist. As you see, the directory structure of Info.plist was flatten. The en.lproj inside the Cocoa app bundle was treated as a WO localized resource, which is wrong behavior. I really can't find documents specify the Info.plist behavior.

Re: Embed a external command-line tool in bundle
Thanks. Now I have another build problem. If I move my command-line tool (actually, it's a cocoa app bundle without UI) under Resources, then the ant build process will move this file MyWOApp.woa/Contents/Resources/MyTools.app/Contents/Resources/Info.plist to MyWOApp.woa/Contents/Resources/Info.plist which leaves both my wo/cocoa apps in corrupt Info.plist state. I look the build.xml without finding anything related to the Info.plist. Why is that happen?

Hi, I have some external command-line tools written by Objective-C that needs to be invoked in my wo app. Of course I could put them in somewhere like /usr/local/bin, etc. But I want to embed these command-line tools inside my wo app bundle so that people don't forget to copy the command-line tools when install the wo app. However, getting path of NSBundle is deprecated API.

Re: WOLips complains about scala WOElement
Thanks Marius. If I want to add support of scala class in WOLips, where should I look at first? I've already checkout the WOLips source code but I have no experience writing Eclipse plugin. Scala helps me writing more concise code not only shorter but also error prune. Actor helps for concurrent programming and Option leads to better API interface that eliminates most null pointer exceptions. Functional operator gives clear intention rather than fiddling with loops and counters. I think WebObjects will get a new life if it leverage the modern language features and design from scala. Look the Play! framework… :) Regards, yllan On Mon, Sep 19, 2011 at 6:47 PM, Marius Soutier wrote: > That's because WOLips doesn't recognize Scala classes.

WOLips complains about scala WOElement
Hi, I'm using WOLips stable with Eclipse 3.6 and scala 2.9.0.1 following the WO wiki setup. Scala is amazing. It reduces a lot of LOC which results more concise and clear code. So I gradually rewrite my project using scala, one class at a time. However, Eclipse gives me errors: The class for 'APILogin' is either missing or does not extend WOElement. line 204WebObjects Template Problems where I write in html. I can still build with ant but it cause error in eclipse. APILogin is a scala class extends other java ERXComponent's subclass. Is there any way to get rid of this kind of error?

Split large application into smaller ones
Hi, I want to split my one large web application into multiple smaller applications so that each part running separately because: 1. Update one application won't affect the other. For example, I want to deploy the admin backend but don't want to restart the customer page. 2. If one JVM crash, the other is still alive. (Although it cost more memory) I'm not sure if my reason is solid. Any comment? If this is the way to go, how to share the data model between these applications? Use something like terracota? Does JRebel help on the point 1? Regards, yllan ___ Do not post admin requests to the list. They will be ignored.

You're right. After setting the shared property to none, Migration works.
What does the share entity means? I couldn't find it on wo wiki.

First Time Database Migration fail
Hi,
I have a project setup with ERXMigration. The migration works except
the first time database initialization.
That is, I have a newly installed server with an empty database and I
want my project create those tables automatically.
But I get errors like this:
Mar 17 17:56:43 MyWebApp[52666] (ERXDatabaseContextDelegate.java:177)
INFO - Database Exception occured: ERROR: relation "preference" does
not exist
<>
Mar 17 17:56:43 MyWebApp[52666] (ERXApplication.java:1307) ERROR -
MyWebApp failed to start.
<>
Mar 17 17:56:43 MyWebApp[52666] (ERXNSLogLog4jBridge.java:43) WARN -
A fatal exception occurred: EvaluateExpression failed:
:
Next exception:SQL State:42P01 -- error code: 0 -- msg: ERROR:
relation "preference" does not exist
<>
where preference is one of my data model. Stack trace was listed as
the following. I can create those tables by running "Generate SQL" in
Eclipse, but that's not a friendly way to install a webapp. Any
insight about this is appreciated.
My Database0.java look like this:
public class Database0 extends Migration {
// downgrade omitted
public void upgrade(EOEditingContext ec, ERXMigrationDatabase
database) throws Throwable {
ERXMigrationTable bookTable = database.newTableNamed("Book");
bookTable.newStringColumn("annotation", 1024, true);
bookTable.newStringColumn("barcode", 64, false);
bookTable.newIntegerColumn("bookID", false);
bookTable.newIntBooleanColumn("duplex", false);
bookTable.create();
bookTable.setPrimaryKey("bookID");
ERXMigrationTable preferenceTable =
database.newTableNamed("Preference");
preferenceTable.newStringColumn("key", 128, false);
preferenceTable.newIntegerColumn("pID", false);
preferenceTable.newStringColumn("value", 1024, false);
preferenceTable.create();
preferenceTable.setPrimaryKey("pID");
// ...
}
}
And I set the properties:
# Migrations
er.migration.migrateAtStartup=true
er.migration.createTablesIfNecessary=true
er.migration.modelNames=Database
Database.MigrationClassPrefix=com.example.migration.Database
dbConnectURLGLOBAL=jdbc:postgresql://localhost/mydb

Re: multipart upload become garbage
I did some tests and verified that the string and multipart binary
POST is correct.
What I did to fix the bug is just removing 8 lines of erroneous code
which attempt to add a zero to the end of the content.
https://github.com/yllan/wonder/commit/175145c3897f7da92be66d7be07802fb5f0dd461
if (req->content) {
content_buffer = (char *)WOMALLOC(req->content_length+1);
strncpy(content_buffer,req->content,req->content_length);
content_buffer[req->content_length] = '\0';
WOLog(WO_INFO, "---content buffer: %s",content_buffer);
strncpy(req->content,content_buffer,req->content_length+1);
WOFREE(content_buffer);
}
The removed code is wrong because:
1. The size of req->content (a byte array) is
req->content_buffer_size, not necessary req->content_length.
if (req->content_buffer_size < req->content_length &&
memset(req->content, 0xFF, req->content_buffer_length))
the_code_will_crash();
2. Even if (req->content_buffer_size == req->content_length), if
req->content didn't contains byte zero, it will crash since the second
strncpy will violate the memory access by one byte.
3. If there is byte 0x00 in req->content, the rest bytes will be
filled with 0x00 by strncpy().
Hence I believed it's safe to removed without affecting other logic.
(CGI Adaptor has almost symmetric structure with fcgi adaptor except
without this part).
But I don't use the adaptor in my production environment because I
realized that very few people actually use this and it's not been well
tested.
Maybe we could do a survey to see which http server/adaptor you use? I
guess apache2 dominates.
Wow, 8 lines of code worth a lot of explanation.
Regards,
yllan

Re: multipart upload become garbage
It's been a while that I'm too busy to dig into this problem.
Anyway, I found the WebObjects FastCGI adaptor is buggy when you want
to upload binary files using form because the code use strncpy() to
copy the contents from HTTP request. It stop copy when a 0x00 byte
occur.
I was a bit surprise that few one complains about this (according to
quick search on google) since it's a severe defect that cause data
loss.
I wonder if people is still using WO fcgi adaptor. Nevertheless, I
have a patched version:
https://github.com/yllan/wonder
In case anyone still use the fcgi adaptor.
Regards,
yllan

Hi, I have a generic version of NSPropertySerialization.arrayForString in my project. I moved the project to another machine, which have WO5.4.3 and Wonder installed.

multipart upload become garbage
Hi,
The following code receives one chunk of multipart uploads and
appending it to a file.
(I have a client app which split the file first and then send the
chunks one by one.)
However, I got trouble when I deploy the code to a snow leopard
machine. I found the file uploaded is not the same as the original
file.
It seems that if there is byte '\0' occurred in the upload stream, the
succeeding bytes all becomes zero.
But this code used to work on both my old server (10.5, WO 5.4.2, Java
1.6 32bit) and dev machine (10.6, WO 5.4.2, Java 1.6 64bit)
What could possibly get wrong?
Regards,
yllan

Re: AjaxObserveField on the radio button?
Thanks, fullSubmit=true solved my case. However, I get another problem, don't know if it's a bug of Ajax.framework or webkit. I use html5 to design my form. There is a pretty stepper next to the field: http://emberapp.com/yllan/images/safari-2 I can get my AOF to notice the change of value when I manually key down the number, but when I click the stepper to change values, AUC didn't get updated. Any insight of this?

AjaxObserveField on the radio button?
Hi, I try to use AjaxObserveField to monitor the change of radio button. However, it's not working. Here is the code to demonstrate the problem: No matter how I click the radio button, it won't change the value of radioValue, option3 and option4 unless I click the submit button. I want to update the AUC when user change the radio selection immediately. Is there any way using AOF to accomplish that? Thanks. Regards, yllan ___ Do not post admin requests to the list.

fetchAllEntities() only returns saved eo?
Hi,
I'm implementing a back-end of a e-commerce system, which do CRUD on product
records.
To return a list of products, I wrote:
return Product.fetchAllProducts(ec);
To add a new product, I wrote:
Product p = new Product();
ec.insertObject(p); // the same ec as in
Product.fetchAllProducts(ec)
p.setTitle("New Item");
return null;
Since I don't want the newly created product object be exposed to
customer––especially when the price value is default value zero, I don't
save the ec immediately. Instead, I have a save and cancel button to commit
the product information.
However, when I add a new product, it's not shown in
Product.fetchAllProducts(ec). How can I get all the product objects in an ec
nevertheless it has been saved or not? Thanks.
Regards,
yllan

Re: [OT] WOLips - Eclipse compatibility?
It's likely something wrong in my system/configuration. Another computer update successfully at the same time, and VMWare running OSX server at the same machine have no problem either.

Report validation error to interface?
Hi, About data validation, there is a common pattern: 1. Present a form to let user input data. 2. Validate the data during input or when form submitted. 3. If there are invalid data, shows error message to each field. To complete this task, I follow the approach that set the error messages to a dictionary which was mentioned at: http://www.stepwise.com/Articles/Technical/WOValidation.html However, wolips complains that it cannot verify key beacsue the keypath 'validationData' is a collection. Also, use a bare string as a key isn't a good idea since tools cannot verify the solidness of your code. So, how do you deal with this situation?

I knew that the WO runtime has been improved over year, and Apple uses many WO in their web applications notheless internal or external. What I concerned about the future of WO is, will Apple promote WO to public? Go to http://developer.apple.com/referencelibrary/ check how many WO documents were produced after 2007. Only 4. The latest one even doesn't finished yet. The example code come with Xcode are a bit outdated and problematic. I still remember how stupid I were last year when I came to WWDC WebObjects Lab. However, even Pascal Robert can't get the Apple examples compiled on my system. I'm not sure if Apple has fixed that, but the environment is unfriendly to new learner. Besides the lack of documentation, another point is how much effort made by Apple goes directly into the community. Of course WOLips will be benefit if WO runtime has improvements, but did Apple ever sponsor WOLips just like what they did to clang? Or any WO-related thing Apple want to make it as industry standard just like block in C, OpenCL, llvm? I mean, if they improve WO just only becasue they have a lot of WO web apps (think about what Adobe will do if they are accessible to carbon frameworks--make a 64bit version without a totally rewrite) and are going to use WO only for Apple's own applications without promoting to public, it's not a good thing to developers outside Apple. >> --I even talked to an Apple >> employee at WWDC08 and he said, "You are using WebObjects?

Snow Leopard compatibility and the future of webobjects
Hi, *** WARNING: I wasn't able to be at WWDC or WOWODC this year so I'm not sure the following is correct. *** According to the website: http://mac.topnewsdigest.com/uncategorized/conflicting-information-about-webobjects/ "Mac OS X 10.6 server no longer support WebObjects." I'm not to talk about NDA-things here. Instead, I'm here to discuss what the above statement mean to us. Since Apple itself is still using WebObjects for MobileMe, iTunes store, AppleStore website, RADAR, devforums and many other system, it's difficult to totally replace all the webobjects app to other technology at once. However, I speculate that Apple will put less and less effort on WebObjects year by year. Although WO 5.5/5.6 is coming, I personally do not expect any other good news from Apple. First deprecates wo-tools, then discontinue the support of WO in the next release of their OS. Apple's attitute is obvious––I even talked to an Apple employee at WWDC08 and he said, "You are using WebObjects? I thought only europeans use that." Of course it's just kidding in a very private conversation, but it more or less shows that not all Apple employees are satisfying with WebObjects, and I guess their percentage isn't low. It seems that this year we have nothing metioned on the WWDC IT session page. No lab either. Even Apple's current wo apps were not good testimonials for WO. Some developers think that Apple's web apps are infamous as 20-century-style and feel frustrated when using them. (It's a long story about how Apple Online Store screw its customer's names with iPhone dev program) Well, it may not be the problem of the essence of WO at all, but the lack of documentation/support is. Maybe why WebObjects is still in Apple is because (1) Apple has no other web technology, (2) Pierre try hard to defending and promoting WO, and (3) both. I predict the future of WebObjects will be totally running from community. Could you share some thoughts with me? Thanks. Regards, yllan ___ Do not post admin requests to the list.

You're right. I don't know if it's proper to handle ECs in my way. Normally I set a variable to hold EC in each components, sometimes I create EOs, insert them into a new EC and track the EC with object.editingContext().

I totally agree your point. Let me break this into two parts--space and time. Memory: it appears that EC isn't suited for insert a lot EO into database because the memory footstep of EC work like this: hold objects in memory, discard or save them to db at once. Other ORM tool like activerecord or python.db seems don't have the concept of EC; they just invoke save() on each objects. In this case, activerecord or python.db are not likely devour all the memory because each object could be collected after they're saved. I'm not saying that which one is better than which. EC is not for doing bulk insert, just like you said. I just want to know if there is way to save each object seperately. Finally I put a line into loop and it works: if (i % 1000 == 0) ec.saveChangs(); Performance: I did some benchmark on my database. 150,000 insertion on the same table: Raw SQL, transaction: 23s Raw SQL, no transaction: 154s EC, saveChanges every 1000 EO inserted: 273s Comparing raw SQL without transaction, EC method is not bad at all. (only 1.7x slower) I don't care about to reduce the wait time from five minutes to half. Totally acceptable. :-) > You should do some basic calculation and estimation before you complain > about something ... Just because you are using the tool wrong, it's not bad > or old.

Re: Lots of EOs slow down the performance
Ah, thanks to all. First thing I tried is AjaxLongResponse. I thought it's acceptable to display a progress bar and let users wait. Surprisingly, I still got a "no instance error" after 150,000 eo created. I then tried the suggestion to replace CSV component with a library that dump the data into files. Nothing changed. I got the csv component wrong. It's not slow to use component. Investigation more, actually, it's slow to do ec.saveChanges() with 150,000 eo inserted. I got broken pipe. I got heap memory error. I have no idea why it break AjaxLongResponse. It's in another thread, isn't it? Anyway, I do ec.saveChanges() each 1000-iteration of eo insertion, and it works. Just curious how do you deal with editingContext.saveChanges() with lots of EO inserted? Um, I don't think 150,000 should be a big deal in 21 century.

Lots of EOs slow down the performance
Hi, There is a task has be done in my wo app: creating thousands of (about 200,000) EOs and generating a csv file containing the information for download. When I create only 1000 EOs, it's fine. But if I create over 20,000 EOs, my page was kill due to no response after 30 secs. So there are EOs created but no csv to download. I checked the code, EO generating is fast. The problem is CSV component. It's just a WORepetition with some WOString that reads the EO's property directly. I have no idea why it take so long to handle 200,000 EOs. (The result file may exceed 5MB, however that's small in 21 century.) How could I improve the performance? Or at least let my page won't be killed after 30 secs. (so I could wait for the csv to be generate.) Regards, yllan ___ Do not post admin requests to the list. They will be ignored.

Unique ID without create entity?
Hi,
I'm now connect my wo app to 3rd party banking service. According to
their API, I need to provide a "transaction id" that is unique for
each transaction or I'll get error.
Sure, it can be done by creating an entity class and use PK as a
unique id. But I don't want to create the entity class since I don't
need that.
What I want is just like this:
SELECT nextval('serial');
Can I do this in webobjects?

Re: WOCookie & Safari
Uh, to be more pricisely, my problem is not because WO won't parse empty cookie properly. My problem is, cookie containing wosid and woinst will be deleted after quitting browser. Hence, there's no way to implement function like "login automatically." Digging into this problem, I found that my session cookie generated by WO 5.4.2 contains empty expire field, which make the browser automatically remove it on quit. Is there any way to keep session cookie after quit browsers?

Re: WOCookie & Safari
Hi,
Is this issue fixed in 5.4.2? I still encountered this problem (Not
only Safari 3, but also FireFox 3 delete my cookie on quit) in 5.4.2.
However, with Andrew's code inside my WOApplication.createRequest(), I
still got the same problem.
What could be wrong in my code?
I rewrote some lines since I don't have LEStringHelper ===
public WORequest createRequest(String aMethod, String aURL, String
anHTTPVersion, Map> someHeaders, NSData
aContent, Map someInfo) {
if (null != someHeaders) {
List cookieValues = (List) someHeaders.get("cookie");
if (null != cookieValues) {
for (int i = 0; i < cookieValues.size();) {
String cookieValue = (String) cookieValues.get(i);
if ((-1 != cookieValue.indexOf("=;")) ||
cookieValue.endsWith("=")) {
StringBuffer sb = new StringBuffer();
String [] pairs = cookieValue.split(";");
for (String pair : pairs) {
int equalsIdx = pair.indexOf('=');
if ((-1 != equalsIdx) && (equalsIdx !=
pair.length()-1)) {
String key = pair.substring(0,
equalsIdx).trim();
String value =
pair.substring(equalsIdx+1).trim();
if ((0 != key.length()) && (0 !=

sb.append(key);

}
}
}

} else
cookieValues.remove(i);
} else

Re: Will Insensitive Like become potential sql injection?
Thanks for your clarification.
If I only want a case-insensible "exact" equality, is there any easy
way to do the following?
select * from table where lower(email) = lower('[EMAIL PROTECTED]');

Re: Localization Help! (was Localizer Default vs. Browser)
Hi Rams,
I'm quite confused about this code. I copied this to my DirectAction
class but it didn't work.
In my project, I have English.lproj, zh_TW.lproj, zh_CN.lproj.
I have my Properies file setup with:
er.extensions.ERXLocalizer.defaultLanguage=English
er.extensions.ERXLocalizer.fileNamesToWatch=("Localizable.strings","ValidationTemplate.strings")
er.extensions.ERXLocalizer.availableLanguages=(English, zh_TW, zh_CN)
er.extensions.ERXLocalizer.frameworkSearchPath=(app,ERDirectToWeb,ERExtensions)
My system/browser is English. Default language is English. I print out
context().request().browserLanguages(), which is exactly English. But
at the top of my action, I print out session().languages() and got
zh_TW (Traditional Chinese) localizer.
Why the localizer change its language after the performActionNamed()
but before myAction actually being called?
My guess is, setup the current localizer not necessary change the
localizer of sessions. Any idea on how to make the code actually work?
Regards,
yllan

log rotation?
Hi, How to setup the log rotation of webobjects app? My app used to produce log file with name like MyApp.log.20080603 automatically. Fine. But after I update my framework, OS and WebObjects, the log file won't append the date to filename automatically except the app terminates! That means, I have only one file MyApp.log, it's overwritten everyday. (Ooops, I lost my log everyday!) When I restart my app, the current MyApp.log becomes MyApp.log.20080716155248451(I just need the /mm/dd) and the new log starts from MyApp.log. How to set the log to old way?

My existing model didn't use ERPrototypes. Now I want to assign each column a prototype, but that will result a lot of changes to my model. For example, some of my attribute (varchar) have external length 32, and there's no varchar32 in the Prototypes popup menu in Entity Modeler, so I'll choose the nearest varchar50. That will change a lot of columns in my existing database!

In my case, I use this feature to generate Migration0, which "generate" tables and columns of my existing db schema. (Well, it didn't generate anything. I create this migration is just because I want to let the ERMigration system know my existing project/model/db and I'll use your trick to avoid them be really executed.) Now I want to change the model a lot, how can I "incrementally" generate those modifications? Like CoreData migration, you have the old model and new one, and it will compare them automatically and give you the default migration file. Regards, yllan ___ Do not post admin requests to the list.

DB Migration Paradigm?
Hi,
Since Chuck said "Use prototype, or you're stupid" in his awesome
session in WOWODC 08, I looked into my project and realized that I
need to modernize it: legacy format (eogenerator / Xcode project / not
fluffy bunny layout), not using prototype in EOModel, using
session().defaultEditingContext(), pageWithName("ClassName"), etc.
Thanks to the help from David LeBer and Pascal, I converted my project
into fluffy bunny during WWDC webobjects lab.
However, when I come back and try to continuely improving my code, I
got a little bit confused about migration.
Today I read an article about migration:
http://www.stepwise.com/Articles/2005/DBChanges/index.html
finally I realized where all the java file in my project like
Database.java, Updater.java, Update0.java come from. Of course I
didn't write the corresponding UpdateX.java file since I have no idea
what it do before. When I changed EOModel, I just manually write SQL
statement and paste into psql.
Now we have er.extensions.migration. How do I convert those old-school
java file into WONDER world? I mean, my app has already run as
production server for a long time. How do I leverage the ERXMigration
into a project that didn't start with ERXMigration at first? After
that, when I make changes to EOModel, I must create an migration class
like MyMigrationX+1 right? Anything else?
And I'm adding prototype to my EOModel, which changes my EOModel a
lot. (each attribute will be assigned a prototype, which my change
their type or width.) Should I write my migration class for every
column manually? Is there any way to generate those migration
automatically?

yllan

EOGeneralAdaptorException when saving EOContext
Hi,
I encountered com.webobjects.eoaccess.EOGeneralAdaptorException when
saveChanges() after inserting an enterprise object into editing
context.
It only happens when I set a relationship of the inserted object.
Without setting the relationship, my app run smoothly.
The inserted entity called Sale. And the problematic relationship
called referenceSale, which joins to sale.
(If a sale has a referenceSale, it will retrieve the value of property
from referenceSale instead of itself.)
Sale:
Column |Type |
Modifiers
--+-+
saleid | bigint | not null default
nextval('sale_seq'::regclass)
clientid | bigint | not null
storeid | bigint |
referencesaleid | bigint |
... other property
Foreign-key constraints:
"sale_client_fk" FOREIGN KEY (clientid) REFERENCES
client(clientid) DEFERRABLE INITIALLY DEFERRED
"sale_store_fk" FOREIGN KEY (storeid) REFERENCES store(storeid)
DEFERRABLE INITIALLY DEFERRED
"sale_referencesale_fk" FOREIGN KEY (referencesaleid) REFERENCES
sale(saleid) DEFERRABLE INITIALLY DEFERRED
I have no idea why this relationship will cause the problem. Searching
on list, I turned on the SQL logging and see there is a
NullPointerException.
No SQL generated. What can I do to investigate this problem further?

Re: WOGenericContainer convert elementName to lowercase automatically
Hi,
Without Wonder, it still produce lowercase only tag.
I wrote my (simplified) version of WOGenericContainer to get the
output respect to the type case of elementName.
I guess it's basic stuff but I'll post here. However, that's a good
practice anyway. (I followed Chuck's book to finish this element.
Thanks, Chuck.)
package your.app;
import com.webobjects.appserver.*;
import com.webobjects.appserver._private.WODynamicElementCreationException;
import com.webobjects.foundation.*;
public class MyGenericContainer extends WODynamicElement {
protected NSDictionary extraBindings = null;
protected WOAssociation elementName;
protected WOElement children;
public MyGenericContainer(String n, NSDictionary m, WOElement t) {
super(n, m, t);
elementName = m.objectForKey("elementName");
if (elementName == null) {
throw new WODynamicElementCreationException("Need
elementName.");
}
if (m.count() > 1) {
NSMutableDictionary tempBindings =
m.mutableClone();
tempBindings.removeObjectForKey("elementName");
extraBindings = tempBindings.immutableClone();
}
children = t;
}
public void appendToResponse(WOResponse r, WOContext c) {
r.appendContentString("<" +
elementName.valueInComponent(c.component()));
if (extraBindings != null) {
NSArray allKeys = extraBindings.allKeys();
for (String k : allKeys) {
WOAssociation binding =
extraBindings.objectForKey(k);
r.appendContentString(" " + k + "=\"" +
binding.valueInComponent(c.component()).toString() + "\"");
}
}
r.appendContentString(">");
children.appendToResponse(r, c);
r.appendContentString("");
}
}

WOGenericContainer convert elementName to lowercase automatically
Hi,
I use WO to generate XML file in my project. After updating my
outdated deploy environment to WO 5.4 / Project Wonder 4.x, I found
the xml generated is different: all the tags rendered by
WOGenericContainer become lowercase.
I use CamelCase before, and match these XML tree with their CamelCase
node name in other client app. Since they all become lowercase now,
the client program no longer match them correctly.
My wod looks like this:
Client: WOGenericContainer {
elementName = "Client";
name=client.name;
}
but the XML code generated looks like:
Is there any way that I can set these tag to CamelCase or just tell
the WO don't convert them for me?

yllan

Ajax in ProjectWonder
Hi,
I leveraged the Ajax support in ProjectWonder into my project recently and
have several questions:
1. It will automatically include prototype + scriptaculous in the header of
output html. However, my html have jquery included, and they will conflict!
The $()
have different semantics in jquery and prototype. Using the AjaxUpdatingArea
will render my existing javascript useless. (Say, $('#id') no longer find
the correct element.) Is re-writing all my javascript with prototype +
scriptaculous the only way I can fix that?
2. This question is not about ProjectWonder. I want to have my WO app look
consistent without copy-n-paste html code on each page, so I make a
component like this:
Template.html
// other css and js stuff
// page structure
Template.wod
Content: WOComponentContent {}
Title: WOString { value = title; }
In each page, I could simply write
// This page's content here
My problem is, using this method, I can't break my css into little part and
assign to corresponding page. How will you solve this problem?
3. I found the examples come with Xcode / ProjectWonder is hard to run for a
newbie. I can't get any example running until I saw this screencast:
http://www.wocommunity.org/podcasts/WO54_Examples.mov
Unfortunately, most of the example except the HelloWorld still can't run.
Eclipse whining:
Caused by: java.lang.IllegalStateException:
warning: There is already a unique
instance for Bundle named 'JavaWOExtensions'. Use
NSBundle.bundleForName(JavaWOExtensions) to access it:
or
Caused by: java.lang.IllegalStateException: Main bundle 'Properties' file
can't be read.
That's very frustrated for a beginner. I mean, why don't Apple make it right
at the first time? Examples are very useful for a beginner comparing to
javadocs. We can't run the example by simply click the build and run button
with standard installation, what's wrong with that?

yllan

NullPointerException in ERXLogger.getERXLogger
Hi all,
I'm a newbie of both WebObjects and server programming who is responsible to
maintain a WO project left by other guy several years ago. I've added some
features and tested in Eclipse. However, during these year, I always
encountered a problem when I want to update the ERExtensions.framework in
/Library/Frameworks.
When I replace the original ERExtensions.framework (whose version is
believed ≤ Project WONDER 3) with new one, I got the exception:
Exception in thread "main" java.lang.ExceptionInInitializerError
Caused by: java.lang.NullPointerException
at org.apache.log4j.Hierarchy.getLogger(Hierarchy.java:271)

And that's the very first line of my project.
public class Application extends ERXApplication {
public static final ERXLogger log = ERXLogger.getERXLogger(
Application.class);
I've my Properties file configured like this:

Hence, I must copy the old ERExtensions to a new environment every time. Did
I miss something?
An extra question: when you add some features to your wo project, how do you
stop the current running wo server and start the new one? I don't know how
to do this so I run my server inside eclipse. I know it's stupid, but I
couldn't find the answer. Maybe it's too basic to document?

Because the project depends on the following frameworks: * ERChangeNotificationJMS.framework * ERExtensions.framework * ERJars.framework * ERJavaMail.framework * JavaWOExtensions.framework * PostgresqlPlugIn.framework I've tried to replace these old frameworks (I guess it's ProjectWonder 2.x) with recent version, says 3.x and 4.0, then my project can't run due to Log4J factory method exception which I totally have no idea what it is. Maybe I mis-configure my environment. I don't know. Before this discussion, I had no idea what can I benefit from ProjectWonder and why the former developer use PW. Now I know that PW fix the bugs of WO. Thanks, Mike. But I still don't know how to incorporate new version of ProjectWonder with my existing project. Currently I'll use Lachlan's method to get it work. Thanks you all!

Re: How to avoid wrong mapping after new object inserted
Hi,
Thanks for Lachlan's response. But I'm a little bit confused.
Does that mean I have to add a button, says, "Refresh the sales," to invoke
the refresh action? Or can I just use the refresh button on my browser to do
that?
Thanks for the help.
Regards,
yllan

How to avoid wrong mapping after new object inserted
Hi,
I have a WO app which allow user to upload photos and associate a sale
record for each uploaded photo.
The record contains the unique ID in postgresql, path of the uploaded files
and other metadata like who and when the file was uploaded.
And I have a page for administrator which lists all the records. For each
record, the app display it's ID, preview, and other metadata.
So it look like this:
Preview: WOActiveImage {
action = download;
data = sale.thumbnail;
mimeType = "image/png";
style = "border: 1px solid black;";
}
Sales: WORepetition {
item = sale;
list = sales;
}
protected Sale sale;
public NSArray sales() {
NSArray sales =
EOUtilities.objectsForEntityNamed(theSession().defaultEditingContext(),
"Sale");
/* Filter the array with some
EOQualifier.filteredArrayWithQualifier(sales,
EOQualifier), snip */
EOSortOrdering sort = EOSortOrdering.sortOrderingWithKey("created",
EOSortOrdering.CompareDescending);
return EOSortOrdering.sortedArrayUsingKeyOrderArray(sales, new
NSArray(sort));
}
public WOComponent download()
{
MyDownloader n = (MyDownloader)pageWithName("MyDownloader");
n.setFile(sale.file());
n.setFilename(sale.canonicalFileName());
return n;
}
It worked with low traffic. However, when we have more and more uploading,
things went wrong. Sometimes I click the download link of, says, SaleID = x,
it didn't give me the file of SaleID = x. Instead, it returns the file of
SaleID = x - 1.
After investigating for a while, I realized that what may cause this
problem. The following is what I suspect:
First, I generate the admin page of current sale records.
After that, some user upload a new file and create a new sale record.
Because I didn't refresh my admin page so it didn't reflect the current
state of sale records. It didn't know the new sale record was inserted.
Hence it will give me the wrong
If this is the case, how can I avoid the problem? I use WO 5.3 on Tiger.
Regards,
yllan

Re: Generic code works on my machine but generate error on another machine
Thanks, Guido. I move the WOFrameworks down but it didn't work. Here is the configuration of my working machine: (without error) http://farm3.static.flickr.com/2299/1812761484_52ff1aba62_o.png And this is another one: (oops! error) http://farm3.static.flickr.com/2003/1811918265_0cef8587bb_o.png You'll notice that the order of WOFrameworks in the latter picture is even lower than the working one. And I tried all possible order permutation. I just wondering if I should revert those generic code to avoid those error...

Generic code works on my machine but generate error on another machine
Hi all, Recently I update my project with Generic code like NSArray. On my machine, it did not generate error in Eclipse 3.2.2 with latest stable WOLips and Wonder 4.0. (Mac OS X 10.4.10, Java 1.5.0_07, WebObjects come with Xcode 2.4) But on another machine, almost the same configuration, Eclipse 3.2.2 with latest stable WOLips, Wonder 4.0, Mac OS X 10.4.10, Java 1.5.0_07, WebObjects 5.3.3, eclipse whining "The type NSArray is not generic; It cannot be parameterized with arguments " and failed to compile. I couldn't figure out what could make this difference. Did I miss something to check? regards, yllan ___ Do not post admin requests to the list. They will be ignored.

Hi, all:
I'm moving from Apache 1.3 to Apache 2. Searching the internet, I
download the latest Wonder and try to build a new woadaptor for
Apache2. Unfortunately, there are some errors occured when making the
mod_WebObjects.so.

I find someone on the mailing-list had the same error because he
configure it with apache 1.3 parameters. Then I check my make.config
file over and over, but nothing obvious.
Here is my make.config:
# This file defines the basic configuration for building the adaptors.

# misc. configuration info. that is needed by other project makefiles.

endif

else
ADAPTORS = CGI Apache
APXS = $(shell bash -c 'if [ -d /usr/local/apache ]; then echo
/usr/local/apache/bin/apxs;else echo
/usr/sbin/apxs;fi')APACHEINCLUDEFLAGS = $(shell bash -c 'if [ -d
/usr/local/apache ]; then echo -I/usr/local/apache/include;else echo
-I/usr/include/apache;fi')endif
#end Linux
# If you are building NSAPI uncomment this and specify where Netscape

# This is typically /opt/netscape/suitespot

ifeq "${CC}" ""
CC = cc
endif
and I have apache2 installed on /opt/local/apache2.
How can I fix the building error and make my webobjects working with apache2?
Thanks!
