You have an unmatched double quote near the end of the  
above   statement.  This might cause the error in your sqlplus  
test, but   probably not in your WO app.


If you eliminate the unmatched double quote, replace the   
remaining  double quotes with single quotes, and rerun the   
statement in  sqlplus, does the error still occur?  Searching   
Google for  "ORA-00972" produced one response that claimed  
that  this bogus  error message can occur when double quotes  
are used.


Another Google search results states that an incorrect  
column  name  can cause this error.  Is it possible that an  
attribute in  your  eomodel has a column name that doesn't  
match a column name  in the  IDEA table?


Art,
First off, I appreciate your help!
I changed the SQL to
UPDATE IDEA SET STATUS = 'A' WHERE (IDEA_OID = 1 AND AVGRATING  
is   NULL AND CATEGORY_OID = 6 AND IDEADESC = 'afdsafadsfasfa'  
AND   IDEANAME = 'fdsfadf' AND IDEAURL is NULL AND NUMRATINGS is  
NULL  AND  PARENT_OID is NULL AND STATUS = 'P' AND SUBMIT_DATE =  
to_date  ('2006-10-08 00:00:00', '-mm-dd hh24:mi:ss')  AND  
USER_OID = 1)

  2  ;
That returned 0 rows updated.
It seems like the SQL generated is off. I think it is the   
SUBMIT_DATE  part. My SQL maybe off.
UPDATE IDEA SET STATUS = 'A' WHERE (IDEA_OID = 1 AND AVGRATING  
is   NULL AND CATEGORY_OID = 6 AND IDEADESC = 'afdsafadsfasfa'  
AND   IDEANAME = 'fdsfadf' AND IDEAURL is NULL AND NUMRATINGS is  
NULL  AND  PARENT_OID is NULL AND STATUS = 'P' AND USER_OID = 1);



What is the oracle data type for the SUBMIT_DATE attribute?


Hi Shaun,
SQL> desc IDEA
Name  Null?Type
-    


AVGRATING  FLOAT(126)
CATEGORY_OID  NOT NULL NUMBER
IDEADESC  NOT NULL VARCHAR2(4000)
IDEANAME  NOT NULL VARCHAR2(255)
IDEA_OID  NOT NULL NUMBER
IDEAURLVARCHAR2(255)
NUMRATINGS NUMBER
PARENT_OID NUMBER
STATUSNOT NULL VARCHAR2(1)
SUBMIT_DATE   NOT NULL DATE
USER_OID  NOT NULL NUMBER
In my EO Model
submitDate maps to SUBMIT_DATE with
External Type of DATE
Value Class (Java) of NSTimestamp
Value (not sure what this might affect) of D


I have this in my notes regarding value type:
--
For attributes with a Value Class of NSTimestamp the following  
value types are defined:


D
t
T
M

These value types affect how the data is transfer between the JDBC  
adaptor and the database. An empty Value Type uses get/setObject()  
on the ResultSet and PreparedStatement. It assumes the database can  
provide a value compatible with a java.sql.Timestamp. A 'D'  
indicates WebObject's JDBC adaptor should use get/setDate. A 't'  
indicates get/setTime(), and a 'T' uses get/setTimestamp(). The 'M'  
value type is a workaround for a bug in some MS SQLServer JDBC  
drivers. It only support java.sql.Date.

--

I thought that I used T usually, but looking at some of my models I  
have nothing set for a lot of the oracle DATE fields. The info  
above indicates that if you only want the date portion then use a  
D, if you want Date and time ie) a timestamp then use T.


Also, I'm using NSCalendarDate not NSTimestamp for valueClassName  
in my eomodels. Using NSTimestamp in the classes. I have a much  
older version of Oracle and WO5.3. FWIW most of my eomodels are  
also quite old now.





Well, I'm going to try some of these options. I really want a  
timestamp. I moved the EOModel to MySQL (on my list of things to  
evaluate anyway) and it worked perfectly. I'm sure it is one of the  
things above. May even try to check some of them if I move back to  
Oracle.


Much, much thanks!

	NSCalendarDate is the "Value Class (Obj-C)" equivalent of the "Value  
Class (Java)" NSTimestamp.  These days, you should probably delete  
the "Value Class (Obj-C)" column and add the "Value Class (Java)"  
column to your eomodels.  However, doing so will make absolutely no  
difference at run time assuming that you're using the correct  
Objective-C equivalents of Java value classes.

It's been a while since I've done something like this, but I think you'll first need to subclass MicrosoftPlugIn (e.g., "MSUnicodePlugin") and override its defaultExpressionClass() method to return the Class object of your MSUnicodePlugin inner class MicrosoftPlugIn.MicrosoftExpression subclass (e.g., "MSUnicodePlugin.MSUnicodeExpression").  In MSUnicodePlugin.MSUnicodeExpression, override formatValueForAttribute().  Get the value returned by super.formatValueForAttribute().  If the attribute's externalType is "nchar", "ntext", or "nvarchar", prepend "N" to the value before returning it.	Then you'll need to ensure that EOF uses MSUnicodePlugin.  The tech note at  should provide enough info to make this happen.Aloha, Art   ___

That's one way.  You could check that the key you were getting was  
actually an attribute of the EO too if you wanted.  Also keep in mind  
that EOF uses take*Stored*Value...() when it initializes your objects  
(and at some other times too -- see next), so you might want to do  
something with that too.


Another way to do it would be to change your eogenerator (I assume  
you're using it or something similar) template to generate code like  
this:


public void setMyAttribute(Object value)
{
takeStoredValueForKey(value, "myAttribute");
didChange("myAttribute", value);
}

Of course, you'll need a common superclass that implements didChange  
however you like.

MSSQLServer Unicode Support

[Dov Rosenberg]

Title: MSSQLServer Unicode Support



I finally have gotten some more time to figure out how to deal with MS SQL Servers unicode support using EOF.

As a refresher – here is the problem:
To support unicode in MSSQL Server, the columns need to be nchar, ntext, or nvarchar (not a problem). In order to store unicode data into one of these columns it is necessary to preface the value with an N such as 

INSERT into locale (recordid, localedesc) values (123, N’日本語');

Otherwise only ??? Will be stored in the database. In order to find the data again you must also preface the values in the WHERE clause with N like:

SELECT * from locale where localedesc like N'日本%';

What I have learned so far:
Chuck Hill suggested using the Read and Write Format attributes of the EOModel to add the N’s. The Read Format he suggested was N %P. When I added that in WO/EOF generated SQL like

SELECT  recordid, N localedesc from locale...;

Which is invalid

For the Write Format he suggested N %V. EOF generated the following SQL:

INSERT into locale (recordid, localedesc) values (N ?, N ?) as a prepared statement with bindings (recordid:123; localedesc:日本語)

Which also didn’t seem to work.

I think I need to either modify the SQL being generated by the MSSQL Server plugin or modify the plugin itself to generate the correct SQL. Any thoughts on the correct direction would be appreciated (as well as some guidance on what and where I need to start).

Thanks in advance

There is a discussion and implementation of what you want in  
Practical WebObjects starting on page 67.  You really need the  
help of the EC.


If I understand it correctly, your editing context subclass posts  
notifications once objects are saved to the persistent data store.


Not quite.  It can notify before a change, after a change but before  
a commit (save changes), and after a commit.



I need notifications being fired on every edit of any EO in my app,  
not in the persistent store, but in the editing context. I need  
that to fire Swing events,


I imagine that this makes quite some difference,  both as this is  
happening client side and for Swing's general architecture.



but didn't point that out in my original post. And, I need them to  
fire *after* object(s) have been edited.


How about overriding all takeValue...() methods? Would that be  
inadvisable?


Yes, that probably makes the most sense for what you are trying to do.


One more question: EOs are not automatically removed from to-many  
relationships after being deleted, even when their delete rule is  
set to nullify. Is this another client side EOClassDescription  
bug, or a standard behavior?


That is standard behavior.  Delete rules are processed as part of  
the preparation work done in saveChanges().  You can call  
ec.processRecentChanges() to force this to happen earllier.


Good to know. Does that make sense? Shouldn't the object store  
reflect the latest changes to EOs managed in that store? Maybe I am  
missing something though...


I don't think that I can argue that this makes sense.  :-)  I have  
always wondered why this needed to be like this.  My best guess is  
that it was done as a performance optimization.

Re: roblem with XSLT Trasformations - was problem generating PDF using FOP

[Travis Cripps]

Amadeo,

Hi.  I created a sample project from your files, and was initially  
getting the same result, with the characters in the file resulting  
from your transform being messed up.


I changed all instances of String -> byte[] and byte[] -> String  
conversions to specify the character encoding and the resulting xml  
was perfect.


The basic changes were to read the xml and xsl into Strings like this:

String sourceXML = null;
byte[] bytes = WOApplication.application().resourceManager 
().bytesForResourceNamed("sourceXML.xml", null, null);

try {
sourceXML = new String(bytes, "UTF-8");
} catch (UnsupportedEncodingException uee) {
uee.printStackTrace();
}

and to get the result of the transformation like this:

try {
	result = ((ByteArrayOutputStream)((StreamResult)  
output).getOutputStream()).toString("UTF-8");

} catch (UnsupportedEncodingException uee) {
uee.printStackTrace();
}

I've posted the simple project to http://apparentmotion.com/ 
downloadables/XSLTest.zip. (47 KB)


Have a great day.

Travis

Re: Detecting eo changes when they happen

[Florijan Stamenkovic]

Hi Robert,



Flor,

I'm not sure if this is a good idea or not, I've never tried this  
myself, but have you looked into registering with EOObserverCenter  
for EOObserving.objectWillChange(Object)?


Maybe it would be possible, in the Swing client scenario where I need  
it. The following code should do it:


public void someEOWillChange(){
new Thread(){
public void run(){
SwingUtilities.invokeLater(new Runnable(){
public void run(){
	...work being done AFTER the event dispatch thread is done, and  
all EO changes are made...

}
});
}
}.start();
}

However, to guarantee that the updating work is being done after EOs  
were changed, the only thread to ever modify EOs would have to be the  
event dispatch thread. I prefer to avoid that restriction, but I will  
give it some thought, thanks for pointing the idea. It should be  
simple, if it works.


Sounds a bit scary to me as far as possibly introducing  
performance, and other various, issues, but just might do the trick  
for you.


Well, it is a client process, and a single user can make changes only  
so fast. I hope it shouldn't be too bad. Optimizations could be made  
not to fire more Swing events then necessary. Still, it's a trip into  
the bowls of EOF, and I am not sure I am up to it :)


Cheers,
Flor

[ANN] Cocoa client for Cayenne ROP

[Tore Halset]

Hello.

Cayenne[1] ROP[2] (Remote Object Persistence) is sort of equivalent  
to WO/EOF Java Client.


We have also started developing a Cocoa framework[3] that let users  
create Cocoa applications in Objective-C that connects to a server  
with Cayenne using Cayenne ROP. Along with the framework is also a  
sample client application. See screenshot[4].


Most of the basic stuff are working. Cocoa bindings are working.  
Relationship handling with automatic setting of reverse relationships  
the Cayenne way are working. Deleting, Named Queries, Committing and  
Faulting are working. CocoaCayenne also has a custom  
NSArrayController that makes life a lot easier.


The network communication in Cayenne ROP are pluggable, but the  
default implementation uses hessian[5]. CocoaCayenne uses HessianObjC 
[6].


Things to do:
 * Better field validation. Like max string length and better error  
messages.
 * Authentication. Currently username and password are stored in the  
hessian service url.
 * Support for ROP distributed events. Cayenne ROP uses XMPP to  
distribute events between clients.
 * Core Data. CocoaCayenne are working with bindings and  
controllers, but full Core Data support would be cool. I do not know  
if this is possible or even needed..


Regards,
 - Tore.

Those are some severe restrictions.

I have read that you can change cgi-bin in /System/Library/

WebObjects/. Is that true ? Are there any other ways to do it ?


You can do it, but you need to edit the adaptor source to do so.   
That might be more effort than it is worth to get rid of 9 characters.

/w/o/a.woa
 You would also need to create a WOContext subclass or use some  
other method to generate the URLs.


Some other ideas:

1. Make aliases for direct actions:

public WOActionResults mrlnAction() {
return myRatherLongNameAction();
}

So you can use a.woa/wa/mrln instead of a.woa/wa/myRatherLongName but  
both will still work


2. Use cookies to store the session ID and instance number if you are  
not doing this already.

I run WO on linux and haven't experienced this problem.

--matt


Hi all,

I was wondering if anyone else is using WO on Linux?  It works great
most of the time, but sometimes it crashes the server which finally
reboots.  The biggest problem is that when the server reboots, WO
starts to load each of the applications and something happens which
stops it after it loads the 2nd or 3rd one.  All the other apps just
keep trying to start and fail.  I have to force restart the
WOServices to fix it.  Anyone seen anything like this?

David.

Detecting eo changes when they happen

[Florijan Stamenkovic]

Hi all,


I am trying to find a way to detect changes eos just *after* they  
happen. If possible the implementation should consider the Author  
object changed, if one of his Books has been unassociated / deleted.


I tried with EOEditingContext notifications, but they are posted only  
at save time. I also could not find anything to fit the purpose in  
Project Wonder, yet.


If nothing like that exists, I am thinking of implementing it through  
a notification posting EOGenericRecord subclass. Any comments or tips  
about this?


One more question: EOs are not automatically removed from to-many  
relationships after being deleted, even when their delete rule is set  
to nullify. Is this another client side EOClassDescription bug, or a  
standard behavior?


Thanks
Flor

Hi All,

Just a reminder, the Chicago CocoaHeads / Chicago Cocoa and  
WebObjects User Group (CAWUG) is holding our next meeting this  
coming Tuesday, October 10th, at 6:00 PM at the Apple Store on  
Michigan Ave.



Agenda:
- Introductions & Announcements
- Sal Sorrentino on ObjectCog
- Q & A
- adjournment to O'Toole's

When:   
Tuesday, October 10th, 6:00 PM

Where:
Apple Store Michigan Avenue
679 North Michigan Ave. (at the corner of Huron & Michigan Ave.)
Chicago, IL 60611
		http://maps.yahoo.com/maps_result? 
ed=gYbE5Op_0Tokf_p7h61dwjbWtjC2r1YehzWw&csz=60611



- Sal Sorrentino on ObjectCog for Mac OS X
	Sal will be discussing ObjectCog, a new open-source web  
application server he is developing Mac OS X. It's written in  
Objective-C.  So it can leverage much of the coolness of the Cocoa  
framework.  Some neat features include zero-configuration load  
balancing, integrated persistence layer, standard and user-defined  
tag libraries, MVC server page design (similar to STRUTS), etc...   
To see a coming soon page, visit objectcog.com (really, something  
will be there someday soon).



- C4
We will also discuss C4.  http://c4.rentzsch.com/

- Q&A

- O'Tooles
	We will continue the discussion at our local watering hold Timothy  
O'Toole's at 622 Fairbanks (2 blocks east of the store).



We also wish to thank the folks who run the theater space at the  
Apple store for letting us have our meetings there, Steve Lorenz  
for hosting our listserve, and Jonathan 'Wolf' Rentzsch for hosting  
the new and revived CAWUG web site.  Thanks all.


Also, if you are working on a project and would like to talk about  
it  briefly / promote it, I think it would be fun for people to  
hear about  other people's projects.  Please email me off line and  
you can talk at  a future meeting or would like a book to review.


Future meetings dates: 11/14/2006 & 12/12/2006

Re: roblem with XSLT Trasformations - was problem generating PDF using FOP

[Jean-François Veillette]

Make sure that everytime you convert from binary to string you  
specify the encoding.
Same thing when you convert from string to binary, explicitely set  
the encoding.


If you do not specify the encoding, java will use the platform  
default (MacRoman on OSX) to do the conversion.


I haven't looked yet at the source you provided, but it has to be a  
problem like that.  It does sounds like you have a string, get the  
binary, get back to string all that without specifying the encoding.

   StreamSource xsl = new StreamSource(aStream);

And instead of passing your XML in as a String ("String xml"), use  
the XML Node class.  Then you can set up the transform on the DOM  
directly:


   transformer.transform(new DOMSource(xml), output);

This should remove your character problems.

Hi all,
I have my data storage on a OpenBase SQL server and data is

UTF-8 format.
The web applications works fine ( I overrided the

for setting the encoding to UTF-8).
You can see my work at:

These are seven websites, but is an unique WebObject applicatiion
that select correct products, graphics, text and css based on
selected site and language.
Now I need to export PDF tacnical sheet of products.
I followed the great Sasha an Chuck's book "Practical  
WebObjects" for

serializing my data in XML format, then trasforming to PDF using
Apache FOP.
Exporting data from EO to XML works fine. First XML become UTF-8
encoded.
When I do  the "SimpleTrasformation" with XSLT provided by Apple
(where the Output Format is set UTF-8), I got bad data  
encoding, and

all accented letters are bad.
Then trasforming again using apache FOP produce really bad  
results.

I tried to do the "SimpleTraformation" using a software (TestXSLT,
http://www.entropy.ch/software/macosx/#testxslt ), a simple  
MacOS X
app that get in input the original XML and the XLST, and  
outputs the

trasformed XML. It works fine, no encoding trouble.
So I think the trouble is inside the Java trasformation engine,  
but I

don't know how to fix.
Can you help me?

WO On Linux

[David Griffith]

Hi all,

I was wondering if anyone else is using WO on Linux?  It works great  
most of the time, but sometimes it crashes the server which finally  
reboots.  The biggest problem is that when the server reboots, WO  
starts to load each of the applications and something happens which  
stops it after it loads the 2nd or 3rd one.  All the other apps just  
keep trying to start and fail.  I have to force restart the  
WOServices to fix it.  Anyone seen anything like this?


Regards,
David.

Re: Sending a request to a url but not returning the page to the user

[Dev WO]

Hello Mike,thanks for the clarification:)Is there something I should read regarding concurrent request? in case I need it next time:)XavierJust to be clear, your access pattern of calling into App A from App B does not actually require concurrent request handling to be enabled.  It's only when an app connects to itself.  That was a "general warning" rather than one specifically targeted at what you're trying to do.msOn Oct 10, 2006, at 5:55 AM, Dev WO wrote:whoa, Thanks for all the replies and input:)I went for the java.net.URLConnectionand also turned on the concurrentrequesthandling (not sure if this can lead to problem...)Thanks Kieran for the sample code, I'm pretty sure I'll be using it:)XavierTHIS IS A RESEND SINCE MODERATOR STOPPED LAST REPLY FOR 9KB OVER!-Or if you don't want to use concurrent request handling, you can dispatch this request in a thread of its own. That way the request generating this DA request gets completed and thus frees up the ap to answer the spun-off second request. Here is a snippet example from a ScheduledTaskDetail WOComponent where I fire a direct action at my current development instance for testing scheduled task direct actions. devFireEvent is a simple component action invoked by a WOHyperlink and DevFireEvent is an inner class in the WOComponent class. the request associated with invoking devFireEvent completes and returns before the direct action request it spawned gets handled in the run() method of the inner class.

Re: modifying the save method for WO Display Group

[Jerry W. Walker]

Hi, Mat,

There are many places you can save the original value of  
transactionptDisplayGroup.selectedObject.passThroughAmt. I often  
override appendToResponse for this.


If you override takeValuesFromRequest, the return from  
super.takeValuesFromRequest, will be the first place that all the  
values entered by the user should be available to you. Before you  
return from the overriding method, you can do all the arithmetic you  
want to those values. However, don't do anything that will change the  
structure of the template, since invokeAction hasn't yet been called.


Regards,
Jerry

I would like to know how to add a little math to the save method of  
a Display Group.


I am using a display group to access records for modifying.  The  
returned records are displayed in Strings and one to be edited is  
displayed in a Field.  The user will enter a number into the field  
and invoke the save component:


public WOComponent saveChanges()
   {
   try {
   this.session().defaultEditingContext().saveChanges();
   } catch (Exception e) {  // could be more specific...
   NSLog.err.appendln( "ViewEditInformation: saveChanges:   
save error: " + e.getMessage() );
   msg = "There was an error saving your changes: " +  
e.getMessage();

   return null;
   }
   msg = "Changes saved.";
   return null;
   }

The value they are modifying is called  
"transactionptDisplayGroup.selectedObject.passThroughAmt".  I would  
like to know how to take the user's entered value and add 15 to it  
prior to the save.  Then I would like to take the value of  
"transactionptDisplayGroup.selectedObject.passThroughAmt" before  
their edit and subtract from it the value the user entered with the  
added 15 and set the value of another field of the displayed group,  
"transactionptDisplayGroup.selectedObject.salonPtRec".   Finally, I  
would like to save the results to the DB.


Any help would be nice.  Thanks,
--Mat

Job opportunity on the Gold Coast (Australia).

[Q]

The Gold Coast based ISP I work for, OntheNet, is currently on the lookout for a competent developer for a full time internal developer position. A good working knowledge of OO, SQL DBs + ORM and Unix are vital, familiarity with WebObjects is highly desirable. This isn't technically a WebObjects developer role as it would involve a variety of technologies, but WebObjects is the direction we are in the process of moving to, so I thought this list might be a good place to look.If you think you might be interested contact me offline and/or send me your resume to [EMAIL PROTECTED].-- Seeya...QQuinton Dolan - [EMAIL PROTECTED]Gold Coast, QLD, AustraliaPh: +61 419 729 806  ___

Re: Sending a request to a url but not returning the page to the user

[Mike Schrag]

Just to be clear, your access pattern of calling into App A from App B does not actually require concurrent request handling to be enabled.  It's only when an app connects to itself.  That was a "general warning" rather than one specifically targeted at what you're trying to do.msOn Oct 10, 2006, at 5:55 AM, Dev WO wrote:whoa, Thanks for all the replies and input:)I went for the java.net.URLConnectionand also turned on the concurrentrequesthandling (not sure if this can lead to problem...)Thanks Kieran for the sample code, I'm pretty sure I'll be using it:)XavierTHIS IS A RESEND SINCE MODERATOR STOPPED LAST REPLY FOR 9KB OVER!-Or if you don't want to use concurrent request handling, you can dispatch this request in a thread of its own.

Re: To lock() or not to lock()

[Kieran Kelleher]

Ricardo,

Also, always make sure you use try-finally to make sure the ec is  
unlocked, otherwise an error condition might branch out and deadlock  
your EOF stack. (Of course, you can stick a catch in there aswell to  
report the error)


ec.lock();
try {
...
...
} finally {
ec.unlock();
}

Hi All,

I have an EOF question regarding locking.  The documentation on  
the EOEditingContext lock() method says the following:


---
Locks access to this EOEditingContext to prevent other threads  
from accessing it. If it has a shared editing context, this  
EOEditingContext takes a reader lock on it as well. You should  
lock an editing context when you are accessing or modifying  
objects managed by the editing context. The thread safety provided  
by Enterprise Objects Framework allows you to have one thread to  
be active in each EOEditingContext and one thread to be active in  
each EODatabaseContext (EOAccess). In other words, multiple  
threads can access and modify objects concurrently in different  
editing contexts, but only one thread can access the database at a  
time (to save, fetch, or fault).

---

My interpretation of this is that I can have thread1 working in  
one editing context and thread2 working in a second editing  
context.  These two editing contexts by default share the eoaccess  
level objects to access the database.  So when either thread calls  
the EOEditingContext saveChanges() or objectsWithFetchSpecification 
() to fetch objects then EOF obtains a lock to prevent the other  
thread from accessing the eoaccess layer and doing a save/fetch at  
the same time.


So it would seem to me that thread1 and thread2 do not need to  
worry about locking their editing context when they are using  
them.   I would have to worry about locking an editing context  
only if I were to have separate threads working on the same  
editing context.  Are these assumptions valid?


No, not at all.  Fetches, saves, etc send notifications to the  
editing contexts in other threads.



Or should I lock the editing contexts?


As Art indicated - yes!

Chuck

Re: roblem with XSLT Trasformations - was problem generating PDF using FOP

[Amedeo Mantica]

Thank you for reply and collaboration

here the link for dile downloads

http://downloads.insigno.net/fileswo.zip

the sourceXML is the XML data grabbed from database (using  
WebObjects's NSXMLOutputStream)

the file is perfect.  (some /u000d for CR/LF, but I think is ok)

the SimpleTrasformation.xls is an Apple provided XLST file for  
removing unuseful data and simplyfing the XML file.


the destinationXML file is the result of sourceXML trasformed using  
SimpleTrasformation.xml

myTrasformer.java is the routine that do the XSLT trasformation.

see the accented letters in destinationXML file...

Amedeo

Hi all,

I have my data storage on a OpenBase SQL server and data is stored un
UTF-8 format.

The web applications works fine ( I overrided the appendToResponse,
takeValuesFromRequest and dispatchRequest methods in Application.java
for setting the encoding to UTF-8).

You can see my work at:

http://www.ivc.it
http://www.muratti.it
http://www.azimutcoatings.com
http://www.pennellificiopuma.it
http://www.lineabird.it
http://www.lineahex.it
http://www.anticasignoria.it

These are seven websites, but is an unique WebObject applicatiion
that select correct products, graphics, text and css based on
selected site and language.

Now I need to export PDF tacnical sheet of products.

I followed the great Sasha an Chuck's book "Practical WebObjects" for
serializing my data in XML format, then trasforming to PDF using
Apache FOP.

Exporting data from EO to XML works fine. First XML become UTF-8
encoded.

When I do  the "SimpleTrasformation" with XSLT provided by Apple
(where the Output Format is set UTF-8), I got bad data encoding, and
all accented letters are bad.

Then trasforming again using apache FOP produce really bad results.

I tried to do the "SimpleTraformation" using a software (TestXSLT,
http://www.entropy.ch/software/macosx/#testxslt ), a simple MacOS X
app that get in input the original XML and the XLST, and outputs the
trasformed XML. It works fine, no encoding trouble.

So I think the trouble is inside the Java trasformation engine, but I
don't know how to fix.

Can you help me?
Thanks

Amedeo

Never mind the superfluous details ... but this gives you a way to do it without turning on Concurrent Request Handling if that is something you want not to do. ... note the httpConn.sendRequest and readResponse are in running in the separate thread..HTH, Kieran    /** Usable in development mode only for developer testing.         Must fire the request in a separate thread since this request will        block because AllowsConcurrentRequestHandling is off. */    public WOComponent devFireEvent()    {        Thread devFireEventThread = new DevFireEvent( selectedTaskEvent() );        devFireEventThread.start();                return null;    }        protected class DevFireEvent extends Thread {        protected CTScheduledTaskEvent event;        protected EOEditingContext ec;                public DevFireEvent() {            super();        }                        /** Create a local instance in a manual lock EC */        public DevFireEvent( CTScheduledTaskEvent newEvent ) {            super();            ec = WKEditingContext.createInstance();            ec.lock();            try {                event = (CTScheduledTaskEvent)EOUtilities.localInstanceOfObject( ec, newEvent );            } catch ( Exception e ) {                log.error( "Error creating DevFireEvent with " + WKStringUtilities.toString( newEvent ), e );            } finally {                ec.unlock();            }        }                /** Fire the event */        public void run() {            ec.lock();            try {                int portNumber = ERXProperties.intForKeyWithDefault( "singletonOperations.fireEvent.portNumber", 80 );                String targetHostName = System.getProperty( "singletonOperations.fireEvent.targetHostName" );                                WOHTTPConnection httpConn = new WOHTTPConnection( targetHostName,                                                                  portNumber );                                String url = "" "singletonOperations.fireEvent.baseUrl" );                url = "" + "?keycode=" + event.keycode();                                if ( log.isDebugEnabled() ) log.debug("fireEvent url = ""Apple-style-span" face="Monaco" size="2"> + url );                                WORequest request = new WORequest( "GET", url, "HTTP/1.1",                                                   null,                                                   null,                                                   null );                                httpConn.sendRequest( request );                                WOResponse response = httpConn.readResponse();            }            catch ( Exception e ) {                log.error( "Error firing event " + WKStringUtilities.toString( event ), e );            }            finally {                ec.unlock();            }        }    } On Oct 9, 2006, at 6:01 PM, Mike Schrag wrote:Random tidbit ... Be careful of using this to call back into yourself (i.e. App A connecting back to App A).  You want to make sure you have concurrent request handling turned on or you will deadlock yourself.ms ___Do not post admin requests to the list.
