Re: Screencast about Localization from WOWODC09 missing

[David Aspinall]

I run into this all the time, converting video from different formats to 
something that works for my kids iPod/iPads.  I downloaded the the mov file and 
converted it with

/Applications/HandBrakeCLI -i WOWODC09W-Localization.mov -o 
WOWODC09W-Localization.mp4 --preset=Universal

It took about 15 minutes on my old CoreDuo mac mini and would be simple to 
script it to convert everything if thats what you want.  The output is 
available at

https://www.dropbox.com/s/q9cj4a66ndntje2/WOWODC09W-Localization.mp4

QT is highly important, so I’d imagine the SDK to be a big deal, maybe there’s 
some business reason or just changing APIs for future work?

keep us posted...

Hi List,

I'd liked to watch the Screencast about Localization from WOWODC09.

It is linked on http://wiki.wocommunity.org/display/WEB/Screencasts?src=search, 
but the linked file 
(http://www.wocommunity.org/podcasts/wowodc/west09/WOWODCW09-Localization.mov) 
does not exist.


Can anyone fix this? Pascal?
Or has anyone a local copy that I could use?

P.S.: The one on iTunes says "This video requires Quicktime which is not 
supported by this version of iTunes" ;-(

Re: Partials and prototype boolean

[David Aspinall]

Can you document the problem you are having with the migration?  From what you 
have said so far the only thing you have changed is to make the column a 
varchar(10) instead of varchar(5).  Also what do you perceive to be the 
migration difference between a root entity vs a partial?  Can you post your 
migration classes?

Re: WOWODC 2013: call for presenters

[David Aspinall]

Hi Pascal,

Most of june works for me, except the last weekend (june 28-July1) as I have a 
wedding to attend.

I would also be interested in doing one or possibly 2 speed round presentations 
(15 minute talk, 15 minute lab?) rather than one big presentation. (I have a 
big thing at the end of May for the eHealth conference .. so something has to 
give a little)

Re: WO & HL7

[David Aspinall]

I've been doing some HL7 work on iOS and although I have nothing specific for 
WebObjects, here are some comments and resources you might find helpful.

- welcome to ACRONYM HELL   If you thought programmers were bad for their own 
terminology, you have not seen anything.  Health Informatics (HI) is absolutely 
awash in crazy terminology.  You may want to start a personal reference doc to 
stick definitions and notes.

- the HL7 v3 standard is a large rambling mess (IMO) and many node definitions 
can conflict with others within the same document!  For example, it is possible 
to have a node like  defined several times within the same document, 
but with different structure. Or it can have the same concept like person but 
create nodes named   ...  each can have different 
structures.

- HL7 v2 is NOT XML.  This is important because the majority of existing 
systems are v2.  Even the newer variations like CDA or XDS often have HL7 v2 
content embedded as values.  Here is an example









- you will also need to understand the code systems and terminology.  For 
example




this is the patient identifier.  The root attribute identified the 
source and the extension identifies the value.  You need to be able to 
distinguish between a root that represents a Drivers License, vs a Hospital vs 
an Insurance Carrier vs a Provincial Health Service   or this






So what is this related document?  Thats easy :)

2.16.840.1.113883.6.1 = LOINC  (Logical Observation Identifier Names 
and Code)
34140-4 = Referral

No problem .. right.  Its the referral request.

My suggestion is to stay VERY tightly focused on only the messages you must 
support, and initially only on the PORTION of the message that you need.

Useful links

HL7.org

You might as well be confused by the vary source of the crazy :)

Re: [Wonder-disc] WebObjects + ERRest + iOS + CoreData (Yes another post on this)

[David Aspinall]

Hi Jesse,

Chuck's right, he is trying to kill me.

I have been planning updates and demonstration code since last year, but paying 
customers come first.  I am supposed to present a practical implementation at 
WOWODC which is only ... a month and a bit away.

I am both freaking out and totally screwed.

If you have specific questions you can send them to the list and I will attempt 
to address them.

Re: ERSync?

[David Aspinall]

Hi Daniel,

I think depending on your shoe box this could work. Let me rephrase where I see 
this going.


Option 1: if your shoebox document is a custom binary store, XML document or 
anything of that nature, then this will NOT work.  Sync'ing something like that 
is really hard.  You might find success using a modified 'rsync' protocol, but 
even then there are going to be risks.  Oh another good example of this would 
be git, svn or cvs.  They only really work well with simple text documents, 
therare not that I know of that will merge (for example) a word document.  They 
basically treat them as large binary blobs.

Option 2:  Each shoebox is a self contained core data database.  This could 
work.  The idea behind ERSync was to leverage the change notification system to 
create very small delta packages between the EOF legacy and the mobile core 
data system.

Hope that helps,
David

RE: Anyone have a phone number formatter?

[David Aspinall]

Message formatting is hard with Exchange WebMail (sucks) but here is a method 
we use to strip out the garbage and then submit the different parsed values for 
area code, number and extension.


/** assumes the phone number is "(111)  222-     extension 444" which we 
reduce to 111222444 and then split up */
public void setFullPhoneNumer( String value )
{
if ( value != null )
{
/** remove everything except numbers */
String reduced = value.replaceAll("^1|\\D+", 
Const.EMPTY_STRING);

int len = reduced.length();
if ( len >= 10 )
{
validateTakeValueForKeyPath( reduced.substring( 0, 3 ), 
"phoneAreaCode" );
validateTakeValueForKeyPath( 
reduced.replaceAll("^(\\d{3})(\\d{3})(\\d{4})(\\d*)", "$2$3"), "phoneNumber");

// this will insert a dash in the phone number, depends 
how you want to store the value
// 
reduced.replaceAll("^(\\d{3})(\\d{3})(\\d{4})(\\d*)", "$2-$3"), "phoneNumber");

if ( len > 10 )
validateTakeValueForKeyPath( reduced.substring( 
10 ), "phoneExtension" );
}
else
throw new NSValidation.ValidationException( "Invalid 
phone number" );
}
}

If you just want output formatting (and not input parsing), it can be  
as simple as this:

 public StringBuffer format(Object object, StringBuffer  
stringBuffer, FieldPosition fieldPosition)
 {
 if (object instanceof Number)
 {
 stringBuffer.append(((Number)object).intValue() == 2 ?  
"Y" : "");
 }

 return stringBuffer;
 }



 /**
  * @throw RuntimeException parseObject is not implemented
  */
 public Object parseObject(String arg0, ParsePosition arg1)
 {
 throw new RuntimeException("parseObject is not implemented");
 }


This is an output formatter that takes a number formats this to "Y"  
if the value is 2 and to an empty string for all other values.  Don't  
ask, legacy data.

Re: ERXPatcher and component templates

[David Aspinall]

Naturally, and we do this all over the place, however this is not a  
simple linear problem.  Its not as if client A gets a traditional  
left nav, plus a custom search field div over the header image, plus  
wants a Calendar on the right column and wants Account list table  
with a column for last contact date instead of last updated date.   
Oh, and client B wants the same but with an EGO image on the right  
and a task list and not the custom search box, and client c wants a  
JavaScript drop down menu, no left nav, so the center content can  
increase 20% and we need 3 additional columns on the Account list 


What I am thinking is we do one 'default' layout with standard  
design, but optionally we could dynamically replace key components  
without the ever growing Switch/Case, if condition ... logic.


We already define the menu in an XML document that the app reads at  
runtime.  So we can place different component items in for pages and  
tab's within pages.  But where one component is heavily customized,  
this 'might' be a better way.  My task to to investigate and compare  
to the more traditional switch/case/ifconditions.  I think this  
'could' be a useful concept (like 'patching') and may be a valuable  
addition to the options available for controlling customization.

ERXPatcher and component templates

[David Aspinall]

Many of you have probably encountered a situation where different  
clients like minor changes to a shipping application's user  
interface.  As we strive to hold onto a common codebase for 90% of  
our product we start to see pages with large numbers of  
WOConditionals checking for one client code vs another.


I am investigating use of a feature like ERXPatcher to switch two  
components at runtime in a simple way.  For example if component  
looks like:


== HTML ==

... ...content...

== WOD ==

wrap: PageWrapper
{
api = value;
}

Now assuming all my PageWrapper classes are API compatible, I would  
like to switch ticoon.client.name.AjaxPageWrapper for the generic  
version.  After examining the the Wonder code I have been able to  
replace the classes (trivial), but the template parser seems to  
insist on parsing the original PageWrapper.wo instead of the  
AjaxPageWrapper.wo   I assume the parser is not using the  
_NSUtilities.classForName() method and simply using the name as  
defined in the WOD.


I was able to intercept this process for Page level components by  
overriding WOApplication with


public void initializeTicoon(NSNotification event)
{
// startup
	NSArray classesToReplace = PropertyTool.ArrayValue 
( "ticoon.replacement.classes" );

if ( ArrayTool.IsEmptyArray( classesToReplace ) == false)
{
		/** install patch components that must be 100% API compatible with  
each other */

String baseclasspath = "ticoon.clients." +
sponsorShortName() + "." +
applicationName();

for ( int i = 0; i < classesToReplace.count(); i++ )
{
String item = (String)classesToReplace.objectAtIndex(i);
String fullpath = baseclasspath + item;
try
{
// example ticoon.clients.bank.AdministratorMain
Class replacement = Class.forName( fullpath );

com.webobjects.foundation._NSUtilities.setClassForName(
replacement, item);
}
catch ( ClassNotFoundException e )
{
/* not found, no replacement, use the default */
Log.Error( "Failed to replace " + item + " with 
" + fullpath );
}
}
}
}

public WOComponent pageWithName(String s, WOContext wocontext)
{
if ( s == null )
s = "Main";

// pass the alternate component name to super
	Class pageClass =  
com.webobjects.foundation._NSUtilities.classWithName( s );

if ( pageClass != null )
s = pageClass.getName();
return super.pageWithName( s, wocontext);
}

So I can replace even the Main page with a custom  
ticoon.client.name.CustomMain and the application will parse  
CustomMain.wo


My next step will be to implement my own template parser and try  
replacing the component name during the parsing process, I just was  
hoping someone had done it already.  Or is there a hook somewhere I  
can override and get the app to parse AjaxPageWrapper.wo instead of  
PageWrapper.wo?

Re: Problem with Subversion and Xcode line encodings

[David Aspinall]

I finally got around to upgrading to XCode 2.4.1, but I still get  
this error.  I have set the line endings in the preferences to "Mac  
(CR)" and the properties to "native".


I get the error when I do "svn diff" also.  Oh and the errors are all  
from the command line.  I wann't using XCode SCM functions.


Is there a way to discover what svn thinks the line ending is, as  
opposed to what it thinks it should be?

I can edit and commit to this repo, but if I add a new file it fails.


If I query the properties

ticoon $ svn proplist -v crypto/HexTool.java
Properties on 'crypto/HexTool.java':
  svn:executable : *
  svn:eol-style : native svn:keywords="Date Author Id  Revision"
ticoon $

I have tried setting the svn:eol-style to CR, LF, I have tried  
changing the line encoding in XCode, all to no success.


Please don't say _use eclipse_, I am looking at that also, but the  
developers have projects and comfort levels with XCode, so I think a  
migration for both CVS and XCode at once is too much.


Subversion is the same on both the Macs and the Linux server
$ svn --version
svn, version 1.4.2 (r22196)

XCode is version 2.4

I don't know what else could be the problem.

Help?

Re: [partially solved] problem with XSLT Trasformations - was problem generating PDF using FOP

[David Aspinall]

I have experienced this also, the problem may be that you must open  
the File stream with an encoding.


I use the methods below and just call

OutputStreamWriter osw = CreateOutputWriter( new FileOutputStream 
("path"), "UTF-8" );


xmlserializer.writeXML( xmlRoot, osw );

osw.close();


/** takes a stream and wraps it for an encoded writer.  Defaults to  
UTF-8 */

public OutputStreamWriter CreateOutputWriter(
OutputStream stream,
String encoding ) throws UnsupportedEncodingException
{
String enc = (encoding == null ? "UTF-8" : encoding);
return new OutputStreamWriter(stream, enc);
}

/** takes a stream and wraps it for an encoded reader.  Defaults to  
UTF-8 */

public InputStreamReader CreateInputReader(
InputStream stream,
String encoding ) throws UnsupportedEncodingException
{
String enc = (encoding == null ? "UTF-8" : encoding);
return new InputStreamReader(stream, enc);
}

Hello,

Data source in Openbase UTF-8 encoded.

In web / html all accented works ok.
serializing in XML than saving to a file seem to be ok, but is bad.

there fore XML -> PDF is also bad.

now I have another, but may be small, problem... the carriage  
return is written out in XML as \u000d... so I have pdf with  
written \u000d instead of correct carriage return.

Re: simple java question with WOComponent sub-classes

[David Aspinall]

Make an interface called SecureConponentInterface (or whatever) and then

 public class SecureComponent extends WOComponent implements  
SecureConponentInterface

 {

 public class ReviewTrans extends WOLongResponsePage implements  
SecureConponentInterface

 {

The sucks part is having to duplicate the implementation (assuming  
there is implementation in SecureComponent).  You could handle this  
by using a utility class with static methods to perform those  
methods, just remember to pass the context and the request.


Just a thought.

Re: Jboss 4.0.x deployment

[David Aspinall]

Ok, I had to comment out the ticoon logging references so it would  
compile without dependancy


http://WOCode.com/cgi-bin/WebObjects/WOCode.woa/wa/ShareCodeItem? 
itemId=459


Here are the notes I added:

- WebSphere (at least for version 5 which our client uses) will not  
tolerate subthread data access. According to my understanding of the  
Servlet container spec, subthreads are not covered and so their  
behavior is not predictable. We experienced all kinds of weird  
behavior due to differences in properties, class loaders and JNDI  
contexts from the 'main' threads and the subthreads.


- I have included some of our TApplication.java subclass code. This  
code shows how we configure EOModels when they are loaded and how we  
install the JavaWSPoolJDBCAdaptor as needed.


- the TApplication code also shows (although it will not compile) the  
logic we use for WebSphere Single Sign on. This same code also works  
with Tomcat for another client who uses NTLM SSO.


- If you build multiple apps into an EAR file, this adaptor must be  
in the /lib/ directory of each application WAR file. Just like the  
WebObjects jar's, it must be there or the class loaders will mess it  
up. If anyone can explain this and or how to fix it (I hate  
duplicating all those jars) I would appreciate the help.

Re: Unable to find entity for object

[David Aspinall]

This line also looks wrong to me.  Why are you trying to change the  
Entity Name?



newLog.setEntityName("TestEntity");


Is this an attribute on your table?  It overrides the default  
EOEnterpriseObject method 'entityName' which I think EOF will be  
needing.


I would recommend removing this column/attribute and trying again. I  
would also change the attributeName while your at it.  Maybe  
'ObjectName' and 'ColumnName' would be better?

What this message usually means is that the entity / model did not

1. App referencing code in the framework from someplace other than  
the .framework
2. EOModel not getting built into the framework (e.g. a project

3. Corrupt .eomodeld directory, index.emodel, or entity.plist  
file.  Check that EOModeler can open the model in the .framework  
that your app is referencing.

Re: WO 5.3 and Tomcat property files?

[David Aspinall]

I encountered problems with WebSphere using properties files.  The  
first problem is that either the Framework properties files were NOT  
read, or they were not read in time (for me to initialize from  
them).  The second is that when the properties are loaded, there is  
only ONE System.properties object.  See:


http://www.google.com/search?q=webobjects+servlet+properties

http://developer.apple.com/documentation/WebObjects/JSP_and_Servlets/ 
SpecialIssues/chapter_4_section_2.html


Additionally you can set properties in the container and WO will load  
them from JNDI.  Which is cool in a way and familiar for clients with  
their own administration processes and policies.


Our solution is to have one property defined in the container to  
identify an additional properties file.  That file we manually read  
(from filesystem/war/ear) using a standard java Properties object and  
then for each property we set the key and value into NSProperties.   
If we do this early enough (Application initialization) then we can  
control/override all the standard WebObjects properties (including  
custom jdbc/jndi connection info).


Hope this helps,
David

Hi,

What the best approach to use property files from development in

System.getProperty("foo")  always returns null under tomcat, but  
works perfectly in development in Xcode.
I tried printing out System.getProperties()  and none of my  
application properties have been loaded only the built in Java ones  
are there.


How does every one else handle this?

1) Manually add properties asin the web.xml file?

2) Avoid properties altogether ?

3) Something else?

I had a quick look at LEConfigServletEnvEntryMergeTool from  
lejstuff from Andrew Lindesay and it looks promising. As it appears  
to convert property files to  in the web.xml file, but  
running it out of the box I got IO.exceptions.

Re: WebSphere connection pool and deadlock - HELP!

[David Aspinall]

Ok, that doesn't seem to be the issue.  I have been searching the web  
(again) and I have identified 2 possible problem areas.


One: seems there may be a problem with WebSphere connection pools  
prematurely closing when the connection/statement/resultset are all  
in different declared scopes.  Seems odd to me but there were several  
reports where the problem (like mine) went away when the connection/ 
statement/resultset were all declared locally, used and released  
within the same scope.  Unfortunately I do not see a way to make  
WebObjects act this way :<


Two: seems there may be a problem with WebSphere connection pools  
where the user (WebObjects) tries to set the autocommit flag (either  
true or false).  Since I know WO does set the connection to  
autocommit false, I am again stuck.


Does this sound familiar to anyone?  Suggestions ... please.

the regular EOF access.  When I give each new EOEdtingContext it's
own ObjectStoreCoordinator, then I get a full stack, and a new
connection for each stack.  EOF seems to find the connections without
any problem, but it is locking objects in one stack (connection) that
I am trying to save in a different stack.  I just cannot see why.
The problem also occurs when I use the session default EC for
everything, so there should only be one stack...

When I kill the connection using EnterpriseManager for SQLServer I
get the following backtrace

WebSphere connection pool and deadlock - HELP!

[David Aspinall]

We have a client who insists on using WebSphere 5.0.  At first  
everything was fine, but all our database connections were created  
using JDBC connection logic.  The client insists we use the JNDI  
naming context for finding and using the websphere connection pool  
and we began to encounter problems.


The first problem was that sub-threads are not permitted under the  
servlet spec and so the behaviour if "undefined".  This shows up  
initially as the subthreads are not able to find the JNDI named  
context so nothing connects.  My fix for this is to perform all  
actions in the current request response loop (no backgrounding).


Now that I have everything connecting correctly I am creating a  
database deadlock constantly.  Basically is seems that fetches are  
locking database rows, but the insert/updates are going to the  
database in a different connection and so are deadlocking on the same  
objects.  No deadlock occurs until an INSERT is sent for an object  
related to a previous fetch.  For example I can insert ActivityLogs  
all day since they have no relationships, but if I insert a new  
ContactLog for a Household .. dead.


I have tried:
- turning on concurrent request handling (thought it might change the  
fetch lock logic)
- put in a custom SQLServerPlugin and overrode lockClause() to return  
an empty string.

- did all editing in the session editing context
- did initial fetches in the session EC, then all edits in a new EC
- did initial fetches in the session EC, then all edits in a new EC  
with a new ObjectStoreCoordinator

- reverting to straight JDBC, no pool works fine.

I'm not sure where to go next.

Other notes:

- WebSphere 5.0.x deployed on SUSE
- MS SQLServer 2000
- WebObjects 5.2.4

- Fastest way to reproduce is to submit a delta XML document via  
DirectAction POST.



Thanks,
David
