Re: Amazon Linux 2023 and Graviton

[John Pollard via Webobjects-dev]

I do appear to have built mod_WebObjects.so

Some things I did on a new Amazon Linux 2023 Graviton instance
sudo yum groupinstall "Development Tools”
sudo yum install httpd-devel

Downloaded the wonder tarball as per the instructions linked below and 
extracted it
cd into Utilities/Adaptors
Edit make.config
Set:
ADAPTOR_OS = LINUX
RC_ARCHS=armv8-a
ADAPTORS = CGI Apache2.4  (this in the OTHER LINUX section)

make

A lot of output and warnings, but it created:
Adaptors/Apache2.4/mod_WebObjects.so
and
Adaptors/CGI/WebObjects

I will not be able to test it for a while, but promising.

Any feedback welcome.

Thanks
John

Paul mentions that the WO Adaptor is easy to build from source; has anyone done 
it on Amazon Graviton hardware?
Would the best instructions be here?:

Also Paul, what instance type are you using; Amazon offer their own Graviton 
instance types more cheaply and with higher performance, but I am on t3.xlarge 
currently. Should I be looking at graviton versions? Is there a WO adaptor 
built for them that can be grabbed? Any other considerations in deploying to 
Graviton?

Amazon Linux 2023

[John Pollard via Webobjects-dev]

Hello,

I am deployed to Amazon Linux 2 and need to move to Amazon Linux 2023 by March 
2025.

Was anyone else in this boat / has already done this migration?

If so, is there anything I should be aware of before I start, or smooth sailing?

I have a very manual deployment, but have extensive notes from moving between 
AL1 and AL2 so hoping that should help.

Many thanks,
John

Re: Monterey mod_WebObjects.so code signing

[John Pollard via Webobjects-dev]

I solved this, so if anyone else needs a pointer:

You can create a self-signed Code Signing Certificate Authority following the 
very good instructions here:
https://www.simplified.guide/macos/keychain-ca-code-signing-create 
<https://www.simplified.guide/macos/keychain-ca-code-signing-create>

You can then create a self-signing Code Signing Certificate as per:
https://www.simplified.guide/macos/keychain-cert-code-signing-create 
<https://www.simplified.guide/macos/keychain-cert-code-signing-create>

You can then sign the library like this:
sudo codesign -s "JPMPLCert" --keychain ~/Library/Keychains/login.keychain-db 
/Library/WebObjects/Adaptors/Apache2.4/mod_WebObjects.so
where “JPMPLCert” is whatever name you called your certificate

I got the error:
unable to build chain to self-signed root for signer …
which I couldn’t resolve, but found a workaround; just sign directly with the 
Certificate Authority cert created above:
sudo codesign -s "JPMPLCA" --keychain ~/Library/Keychains/login.keychain-db 
/Library/WebObjects/Adaptors/Apache2.4/mod_WebObjects.so
where “JPMPLCA” is whatever you called your Certificate Authority

Then add it to the LoadModule line in your apache config:
LoadModule WebObjects_module 
/Library/WebObjects/Adaptors/Apache2.4/mod_WebObjects.so “JPMPLCA"
where the bit in quotes at the end is whatever you ended up signing your 
library with earlier

Now when do my apache configtest I see:
Allowing module loading process to continue for module at 
/Library/WebObjects/Adaptors/Apache2.4/mod_WebObjects.so because module 
signature matches authority "JPMPLCA" specified in LoadModule directive

and the world is right again

Monterey mod_WebObjects.so code signing

[John Pollard via Webobjects-dev]

Hello,

After switching to Monterey

apache configtest

gives:

[Tue Feb 08 17:25:53.363409 2022] [so:error] [pid 2017] AH06665: No code 
signing authority for module at

If anyone has jumped through this hoop, could you point me in the right 
direction?

I only need this for running to test things out in development, it is not a 
deployment environment.

Many thanks,

apache 2.4 mpm prefork or event?

[John Pollard via Webobjects-dev]

Hello list,

I recently moved to Amazon Linux 2 and apache 2.4

In /etc/httpd/conf.modules.d/00-mpm.conf

If I opt for prefork, I see this in the error log:

The mpm module (prefork.c) is not supported by mod_http2. The mpm determines 
how things are processed in your server. HTTP/2 has more demands in this regard 
and the currently selected mpm will just not do. This is an advisory warning. 
Your server will continue to work, but the HTTP/2 protocol will be inactive.

If I instead opt for the event module

I intermittently get segmentation faults logged, such as:
[Tue Jan 11 07:35:36.570934 2022] [core:notice] [pid 2485:tid 139715274359360] 
AH00052: child pid 3132 exit signal Segmentation fault (11)

Should I be able to use mpm event and how important is having support for 
http/2? I believe I have the correct mod_WebObjects.so for apache 2.4, works 
fine with prefork

Many thanks,
John

Re: Default mysql TIMESTAMPS not allowed NULL

[John Pollard via Webobjects-dev]

Thank you Tim and Ray,

Just moved to Mac OS 10.15.7 in development which has given me the headaches
I have installed the latest mysql 8.0.22
Java 8 (I use Java Web Start which keeps me on 8 for now)
As my production system is on mysql 5, I found I had to use 
mysql-connector-java-5.1.44 which currently keeps both environments happy with 
regards establishing the connection. So this may be the issue.
I will plan to upgrade mysql in production and get everything in line, I just 
don’t want to do too much all in one hit.
So for now I will go down one of the coding routes, perhaps just set it in 
validateXXX() for each entity.
Thanks for the more generic coding options Tim which I will also look at.

John

Default mysql TIMESTAMPS not allowed NULL

[John Pollard via Webobjects-dev]

Hi again list,

My move to Catalina forced me to mysql 8. The previous version allowed NULL to 
be passed to TIMESTAMP fields causing mysql to set them automatically, but the 
NULL passed in the INSERT statements causes an error.

From reading around I believe they should be passed as a blank “” rather than 
NULL in order for mysql to default them. I should update my Wonder snapshot as 
perhaps it is fixed in Wonder now, but I am wary of making too many changes all 
at once. The lesson I suppose is to keep all aspects reasonably up to date in 
good time!

Is there a quick way to set all fields that are of type dateTimeStampPrototype 
in the EOModel to be blank rather than NULL? Or I could just set them to now in 
code, but is there one place I can do it rather than in every entity class?

Thanks
John

Re: move to mysql 8 on Catalina jdbc Incorrect DATE value: '??’

[John Pollard via Webobjects-dev]

Very kind of you. All I did was swap mysql-connector-java-8.0.19.jar in place 
of the more recent mysql-connector-java-8.0.22.jar and it resolved my problem. 
Using the latest 8.0.22 version, I get the "Incorrect DATE value: '??’at” error.

Should I update my Wonder code anyway? My last grab of it was in 2015! I have 
been scared to touch it.

Obviously it is a concern that the latest mysql jdbc connector has this problem 
and I would be interested to know whether anyone else had tried 8.0.22 with 
success. For now I can work with the 8.0.19 version.

Thanks
John

move to mysql 8 on Catalina jdbc Incorrect DATE value: '??’

[John Pollard via Webobjects-dev]

Hello WO list,

I upgraded my Mac to Catalina and found mysql 5 no longer ran, so installed 
mysql 8

I switched to the latest mysql-connector-java-8.0.22.jar

I note the following error when I run an application:

Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class 
is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the 
SPI and manual loading of the driver class is generally unnecessary.

My connection dictionary:
URL: 
jdbc:mysql://localhost/BetRankDB?user=root&capitalizeTypeNames=true&useUnicode=true&characterEncoding=UTF-8&sendFractionalSeconds=false
Driver: com.mysql.jdbc.Driver
Plugin: MySQL

I tried removing the Driver, but got the same error message. So I changed 
Driver to com.mysql.cj.jdbc.Driver and that error went away.

However, I get the following exception:

er.transaction.adaptor.Exceptions  - Database Exception occured: Incorrect DATE 
value: '??’at

I confess I haven’t updated Wonder code for a very long time, could that be the 
issue?

Many thanks for any pointers.

Re: MacOS WebObjects Apache 2.4 Adaptor

[John Pollard via Webobjects-dev]

Is there a simple way to determine what version of mod_webobjects.so is 
installed?
I notice my live server has a 2011 dated file! This is on Amazon Linux
My dev box is a Mac and has a 2014 dated mod_webobjects.so
I am not inclined to tinker too much, but thought I would ask!

Hmm, interestingly on my live server I see:
httpd -version
Server version: Apache/2.2.34 (Unix)
Server built:   Nov  1 2017 18:47:16

On my dev box I see:
Server version: Apache/2.4.34 (Unix)
Server built:   Feb 22 2019 20:20:11

Would I be advised to try to get the live server to 2.4?
Again I am reluctant to tinker too much while things are humming along nicely.

Thanks
John

I have now realised the command line is the JDK and the plugin the JRE, have

Re: Advice on whether to upgrade Eclipse / WOLips from Eclipse Mars 4.5

[John Pollard]

Aha, it seems I have some Java version issues.
Sys Prefs, Java says I have v201 located at /Library/Internet 
Plug-ins/JavaAppletPlugin/plugin/Contents/Home/bin/Java

In the shell
which java
/usr/bin/java
is a link to 
/System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java
which is the older version and also the one Eclipse is picking up

I will look at resolving the two versions.

Thanks

Re: Advice on whether to upgrade Eclipse / WOLips from Eclipse Mars 4.5

[John Pollard]

I installed 2018-12 but on attempting to add WOLips47 I received the following 
error:

Unable to read repository at 
https://jenkins.wocommunity.org/job/WOLips47/lastSuccessfulBuild/artifact/temp/dist/content.xml.
sun.security.validator.ValidatorException: PKIX path building failed: 
sun.security.provider.certpath.SunCertPathBuilderException: unable to find 
valid certification path to requested target

Menu Eclipse -> About Eclipse -> Installation Details -> Configuration
java.runtime.version=1.8.0_60-b27
which I believe is up to date on my Mac

Any pointers to working round this?

Thanks
John

Re: Advice on whether to upgrade Eclipse / WOLips from Eclipse Mars 4.5

[John Pollard]

Thanks to all for this torrent of great replies and it sounds like I will try 
the very latest then, the 2018-12
I do use EOModeler so assume that will work fine too.
Gordon, I do have my own notes from my Sep 2015, but if your notes are handy 
I’d appreciate those too being a lot more recent.

Advice on whether to upgrade Eclipse / WOLips from Eclipse Mars 4.5

[John Pollard]

Hi list,

My last update of Eclipse/WOLips was in 2015 and I am on Eclipse Mars 4.5.2 + 
wolips / subclipse and all works fine.

Should I move up (to Eclipse/WOLips 4.7?) or not much reason to do so?

Many thanks for your advice,

John

Re: JavaMonitor to start a blocking application?

[John Pollard]

Thanks all for replies.
Giles Palmer also recommended ScheduledExecutorService directly so I have good 
options to look at.
I realise I don’t need to use JavaMonitor, but it keeps things managed in one 
place.
Thanks

JavaMonitor to start a blocking application?

[John Pollard]

Hello WOers,
I use JavaMonitor for a number of web apps just fine.
I have another app that is a WO app but it isn’t an event driven web app; when 
it runs is just gets on with a never ending task.
Is there an easy way to use JavaMonitor to just start this when the machine 
first boots up, but not try to check it is still alive (no heartbeats)?
This would be a bit easier than using cron for me.
I suppose ideally I would like the app to be responsive to JavaMonitor so it 
can be shown to be alive / be killed & restarted, whilst also doing its never 
ending task. Is it possible to do this with a background thread in my 
ERXApplication class or will that now work nicely with EOF etc.
Thanks
John

Eclipse WOLips System Frameworks setting not picked up

[John Pollard]

Hi List,

If I set build.properties in my project, the WO frameworks are found ok when I 
do a WOLips Install

but if I instead set it in Eclipse, Preferences, WOLips, System Frameworks

the frameworks are not found when I do WOLips Install

A command line ANT build works ok where I pass -Dwo.system.frameworks=…...

I recently moved to Eclipse Mars and wolips44

Why might the WOLips System Frameworks preference not be picked up?

Thanks
John

ERDistribution

[John Pollard]

Can anyone say what ERDistribution adds and whether it should be used as a drop 
in replacement for EODistribution for Java Client apps? Is there any 
documentation around it, the wodev list seems to draw a blank on this topic. I 
currently use EODistribution.

I spotted it only because after updating my copy of Wonder, the only error I 
see relates to ERDistribution, JavaClient WO saying: Either one of 
'applicationClassName' or 'interfaceControllerClassName' should be bound. If 
anyone can explain why that error is present, that would also be of interest.

Many thanks,
John

Re: Wonder git update

Just to add… I have no local changes to preserve, I just want to take a 
snapshot.
I think this might do it?

git fetch —all
git reset —hard origin/master

Wonder git update

[John Pollard]

Hi List,

I would like to grab the latest WonderSource, last grabbed Feb 2013.
I can see how to clone the WonderSource tree and pull the bits I need into 
Eclipse.

Should I repeat and clone the whole tree or can I update my fairly old 
WonderSource tree it in situ?

I have a note that this used to do it:

cd WonderSource
git fetch upstream
git merge upstream/integration

though I suspect that is no longer correct.

Thanks
John

Re: Eclipse recommended version for latest wolips and wonder

[John Pollard]

Answering my own question, this page sheds more light: 
https://wiki.wocommunity.org/display/WOL/Install+WOLips+with+Eclipse+Update+Manager
 and I see Eclipse 4.4 is the latest supported by wolips (though I actually 
have gone with Eclipse 4.5).

Eclipse recommended version for latest wolips and wonder

I am updating from Eclipse 3.7 Indigo in order to move from Java 6 to Java 8. 
The Wonder install guidelines are a bit out of date, assuming I am looking in

Should I get “Eclipse IDE for Java Developers” version 4.5 for Mac OS X?

Re: Values in URL for WOCheckBox?

[John Pollard]

Thanks Chuck,

What I have is:

nextOptionalExtraCheckBox: WOCheckBox {
checked = isNextOptionalExtraSelected;
name = getNextOptionalExtraCheckBoxName;
}

If I add value = true; I get an error:

- exactly one of “checked” or “value” must be bound.

I am struggling to juggle a combination of settings that starts with unchecked 
boxes and puts any checked ones to a value of 1/true.
As I say though it doesn’t actually matter as unchecked ones don’t get passed 
in the DA call, so I just detect presence.

John

Values in URL for WOCheckBox?

[John Pollard]

Hi List,

I have a direct action method called from a form submission, where the form 
includes WOCheckBox. I note that if the check boxes start unselected, then any 
that are selected prior to the form submission appear in the direct action url 
like this:

si_218515=0.0.23.5.1.20.0.6.5.1.5.7.1.1.1

Where si_218515 is the name I assigned to the WOCheckBox

I would have expected a value of true/false or 1/0. What am I actually getting 
with 0.0.23.5.1.20.0.6.5.1.5.7.1.1.1 and can I change it to be something 
shorter, as all I care about is whether a check box is selected.

In fact I can work on the presence or absence of any value as unchecked boxes 
are omitted, but it would be nice to shorten the url and ideally have a true or 
false.

Thanks
John

Re: Canonical links and instance number in urls

[John Pollard]

Just as a follow up, we have ended up putting the canonical url on every page, 
which apparently isn’t a terrible thing to do: 
http://moz.com/blog/rel-confused-answers-to-your-rel-canonical-questions 
<http://moz.com/blog/rel-confused-answers-to-your-rel-canonical-questions>

If there is a way to know what exact original url was in the users browser 
within the app, before the (presumably) wo adaptor adds in or changes and 
instance number before /wa/ then I would love to know. I expect we must be 
doing something wrong somewhere for google to be getting hold of a url with an 
instance number in the url in the first place.

Canonical links and instance number in urls

[John Pollard]

Hi List,

We have a possible issue on our web sites with google thinking we have 
duplicate content because the following reach the same page:

/5/wa/
/wa/...

I am not quite sure where google gets the links containing instance numbers, 
but we would be ok with it if we could include a canonical link instruction in 
the page head, to give the correct url.

I don't want to include the canonical link in the head if the url is correct 
already, in the second case above. Perhaps this is allowed but it doesn't seem 
very nice, I would prefer only to give such a link when I know the url seen in 
the browser isn't the canonical one.

But I am struggling to know within the application what actually was the 
original url seen in the user's browser.

When I log out request.uri() I *always* see the instance number in the url, 
e.g. .../1/wa/... (for either of the above examples) which is ok, but it means 
I can't tell whether the real original url seen in the browser is the canonical 
form or not (the one without the instance number).

Help!

John

Re: Java Certificates applying to WebObjects

[John Pollard]

Bart,

Very sorry for the slow reply, here are some notes I made when I did this with 
an Inrax Client java application. I found that it worked ok using IE on windows 
(for me I had a copy of Win XP on VMware fusion on my Mac which I used). I 
think I have mangled all the private bits!

Renewing with Tucows. 3yr,  $195 Use IE on Win XP (as described below)
By email they told me:

The process for renewing your code signing certificate with Comodo is the same 
as when you first purchased with us. Simply sign into your Author Resource 
Center account at https://author.tucows.com/ then look to the the left where 
you'll find a link that says Code Signing Certificates. There, you can choose 
the length of your certificate and proceed to purchase. The expiration date 
will coincide with the date of your new purchase; the remaining days do not 
roll over. Take into consideration that it can take a few business days for 
Comodo to complete the validation process once you have provided your 
information.

Process: 
http://revolution.screenstepslive.com/s/revolution/m/10695/l/92953-purchasing-a-code-signing-certificate-for-windows-from-tucows

Questions on the cert. page:
(Optional) Enter the Contact Email Address to appear in your Certificate: 
supp...@inrax.com
I kept the default values for the rest:
CSP: Microsoft Enhanced Cryptography Provider 1.0
Key Size: 2048
Key Storage: In the CSP?
Exportable: yes
User protected: no

On Next, the IE browser pops up a message that say it is requesting a 
certificate for me, Agree
I then entered my first and last name and agreed to the licence agreement
Then: "Your details have been received and are awaiting validation...

Now wait until Comodo approve the certificate request before the certificate 
can be retrieved and signed

I had to email a bank statement to d...@comodo.com and you can also email that 
address to check on progress. They then email me a link like 
https://secure.comodo.net/products/CollectCodeSigningCert?collectionCode=T3OcK3XXX
 [DO ON IE AGAIN] which pops up a window about installing a certificate, agree 
to that.

Again, do the next step from IE on Win XP to save a lot of trouble and then 
once installed in IE browser, export from there and use the resulting file 
which is a .pfx (type of keystore), see
https://support.comodo.com/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=225
Based on this web page:
In IE, Tools, Internet Options, Content, Certificates
Select the certificate in the list and Export...
Next, Yes Export the Private Key
PFX type and tick only "Include all certificates in the certificate path if 
possible"
Add a password to protect the key

View the keystone file content:

keytool -list -storetype pkcs12 -keystore file.pfx

Keystore type: PKCS12
Keystore provider: SunJSSE

Your keystore contains 1 entry

824ae68d8b5-20e8-4320-9751-fabea7c3665f, Dec 3, 2013, 
PrivateKeyEntry, 
Certificate fingerprint (MD5): C6:BC:4A:71:6C:AA:FE:C5:3E:9D:0E:D8:X

The comodoKS.pfx file is then put on dev box under mpl/security and on 
deployment boxes under /Users/admin/wo and the signJar script in that directory 
must be updated to have the mangled string that is seen within the keystore 
listing, viewed as described above.

Alter signJar to refer to the correct new cert. keystore file and then 
signAllJarsComodo

My signJar script is passed the name of each jar file that needs signing (all 
of them including 3rd party ones) contains:

echo YOUR_PASSWORD | jarsigner -storetype pkcs12 -keystore 
./comodoKS_20161202.pfx $1 
824a7beccad581_5c84d8b5-20e8-4320-9751-fabea7c3665f

where you change YOUR_PASSWORD and $1 is the jar file passed to the script as a 
single argument and the last bit is your private key

I hope that helps
John

Daniel,

If this is a Java Code Signing certificate, we use Tucows 
https://author.tucows.com/ to buy a Comodo certificate which cost $195 for a 3 
year renewal last time round. If you need more info, let me know and feel free 
to email off list on this one.

Re: Precompiled WOAdaptor for apache 2.4

[John Pollard]

Patrick's instructions on how to build worked for me, compressed for dummies 
(like me) as this:

Install XCode (6.1)

cd /Applications/Xcode.app/Contents/Developer/Toolchains
sudo ln -s XcodeDefault.xctoolchain OSX10.10.xctoolchain

vi /tmp/Adaptors/Apache2.4/Makefile
and remove the arg -macosx_version_min 10.5

cd /tmp
svn co https://github.com/wocommunity/wonder.git/Utilities/Adaptors
cd /tmp/Adaptors
gnumake (some bits fail, but carry on)
gnumake Apache2.4

This creates:
mod_WebObjects.so
in /tmp/Adaptors/Apache2.4

I haven't tried using it yet, out of time today. If anyone has advice on 
changes needed to httpd.conf for using Apache2.4 with WO, that would be of 
interest. I will report back once I have tried it.

John

Re: Precompiled WOAdaptor for apache 2.4

[John Pollard]

But also ruby, is that also painless and lightweight enough to justify 
installing in order to pick up homebrew?

Are you saying that apache2.2 ends up existing in parallel with apache 2.4 
after doing this?

I have read through more list postings and I see that mod_proxy can be used to 
sidestep mod_webobjects and wotaskd; is this the likely future path / already 
being done for deployments as well as development environments?

Is there likely to be a wiki page to help explain the transition? Is 
mod_webobjects likely to be made compatible with apache 2.4?

Many thanks,

Re: Precompiled WOAdaptor for apache 2.4

[John Pollard]

Looking at that sequence for reverting to apache 2.2, which I am also thinking 
of doing, I see that I first need to install homebrew. The instructions to 
install homebrew use a ruby command, so presumably I also need to install ruby 
to get homebrew? I got nervous at this point.

How about TimeMachine to bring back the 2.2 install dirs from pre-yosemite, 
based on paths here? 
http://wiki.apache.org/httpd/DistrosDefaultLayout#Apache_httpd_2.2_default_layout_.28apache.org_source_package.29
Would that work?

Alternatively I might be able to limp along using Direct Connect for a while if 
the WO apache module is likely to be updated by someone clever soon enough?

Thanks
John

Re: EOCustomObject valueForKey avoiding infinite recursion

[John Pollard]

If after clearing the undo stack I open a dummy undo group i.e.
undoManager().removeAllActions();
undoManager().beginUndoGrouping();
Then things do seem to run ok, so there is a dummy undoGrouping for the java 
client server side request handling code to close off, but seems a bit 
outlandish to do this, asking for more future problems?

Re: EOCustomObject valueForKey avoiding infinite recursion

I instead used the property er.extensions.ERXEC.editingContextClassName to 
specify the ForgetfulEC which I had  change to be subclassed from ERXEC

However, with the call to undoManager().removeAllActions() seems to tread on 
some toes; a later endUndoGrouping() called by some other code is now falling 
over with this exception...

Re: EOCustomObject valueForKey avoiding infinite recursion

[John Pollard]

Thanks, I will give this a try.
I am using Java Client, not sure about the "applets" bit.
Currently the client session ec is created using 
ERXEC.newEditingContext(objStore)
So should I...
Create a sublcass of ERXEC.DefaultFactory and override _createEditingContext() 
in it, to return a ForgetfulEC
Install my factory using ERXEC.setFactory()
Anything else?
Thanks
John

Re: EOCustomObject valueForKey avoiding infinite recursion

[John Pollard]

Hmm, hairy palms, not sure I want that, but thanks for this anyway. The related 
attribute is a to-one relationship, does that mean it is a FK attribute? It is 
the to-one relationship that becomes null against my will and I need to find 
out where/why.

I have now cobbled some code up in takeStoredValueForKey() which avoids the 
recursion when checking the existing value using storedValueForKey() and 
ignores the (temp) null value caused by clearProperties() when the EO is 
invalidated. Hence I believe I now have the code to scream if my property is 
set to null from a pre-existing value and I should get an email + stack trace 
to report the exciting news. These intermittents are about once every two 
months so will have to wait.

Re: EOCustomObject valueForKey avoiding infinite recursion

[John Pollard]

So committedSnapshot records the last committed state so that as yet unsaved 
changes can be compared? My value shouldn't change at all in an update ever so 
this might be a good place to check for null -> B happening.
What I have noticed in takeStoredValueForKey is that clearProperties() is 
invoked if the EO is invalidated, which does lead to a B -> null -> B 
transition where in fact the value doesn't change, so I have to ignore the case 
where the property goes to null temporarily if an EO is invalidated. Though I 
haven't checked that willUpdate() is impacted by clearProperties() in the same 
way.

Re: EOCustomObject valueForKey avoiding infinite recursion

[John Pollard]

Apologies, I meant takeStoredValueForKey(). Within there, how can I safely see 
what the value currently is when when this method is called, before I invoke 
super. takeStoredValueForKey() to take on the new value?

Re: EOCustomObject valueForKey avoiding infinite recursion

[John Pollard]

Ray,

Thanks for the thought. I do want to log the stack trace but as I can't predict 
when this issue might happen and it is rare. I want to narrow down to the close 
circumstances first, or else I will be logging thousands of these stack traces 
in normal operation when there isn't a problem. What I need to do is detect 
when a given attribute is changed from non-null to null (which should never 
happen), so I need to check what it was before it is being set i.e. just check 
it was non-null before being set to null.

EOCustomObject valueForKey avoiding infinite recursion

[John Pollard]

Hi List,

In some debugging within takeValueForKey() I want to find out if the key 
already has a value set. If I call valueForKey() or storedValueForKey() and the 
value isn't already set I get infinite recursion as it triggers a fault and 
tries to load with takeValueForKey() and so on.

I am trying to debug where a value is being set to null, but apparently not 
going via validateXXX() or setXXX() methods, so I want to trap the case where 
the takeValueForKey() is passed null when the key value was previously non-null 
and log a stack trace.

Thanks
John

My workaround code does actually only rely on the order in the URL itself, as

Re: Retaining order of values in a url

[John Pollard]

My workaround to put them back in order, using a TreeMap to sort on the index 
position within the URI.

NSArray formKeys = request().formValueKeys();
String uriStr = request().uri();
TreeMap orderedKeysMap = new TreeMap();
for(String nextKey : formKeys)
{
orderedKeysMap.put(uriStr.indexOf(nextKey), nextKey);
}

Retaining order of values in a url

[John Pollard]

Hi List,

I note that WORequest.formValues() jumbles up the order of the values from a 
url. Is there a simple way to get them in order, or do I need to parse them out 
myself? I understand that normally the order shouldn't be important, but I have 
what I feel is a reasonable purpose for needing to know the order.

Thanks

ERXEC RR loop locking

[John Pollard]

We have an application that uses ERXECs yet exhibits deadlock which appears 
resolved with introduction of manual lock / unlock in at the start and end of 
performAction.. within a subclass of ERXDefaultRouteController.

Is RR loop locking of ERXECs automatic for every EC, or just for default ECs?

My impression was that when using ERXECs, it is wise and unnecessary to do any 
lock/unlock manually at all.

Thanks

Re: How to create a non-web EOF application

[John Pollard]

Thanks JR and David. I will use the lazy approach of overriding run() in 
Application.
I will also pass -WOLifebeatEnabled false as I don't want this application to 
talk to wotaskd
If anyone can tell me if this flag would achieve that, I would be interested 
and without it would the app in fact be pinging wotaskd and would wotaskd take 
any notice if it wasn't "in charge" of this application?
Thanks

How to create a non-web EOF application

[John Pollard]

Hi List,

What is the sensible way to create a new application in Eclipse that uses EOF 
and a model, plus draws on Wonder bits and bobs, but isn't a web app i.e. has 
no web front end? I think Eclipse once had an EOF Application type, or I may 
have mis-remembered that.

I can create a new Wonder app in eclipse and just not have any request / 
responses and launch my code from Application(), but that feels a bit wrong. I 
don't want it to talk to wotaskd or be started from JavaMonitor.

Thanks in advance.

John

Re: ERXObjectStoreCoordinator dispose not releasing database connection?

[John Pollard]

Thanks Aaron,

In mysql I use:
show status like "Threads_connected";

to see the two connections added when I create an OSC in the session, key 
elements being:

objectStoreCoordinator = new ERXObjectStoreCoordinator(true); // true = close 
db connections on closing
this.ec = ERXEC.newEditingContext(objectStoreCoordinator);
setDefaultEditingContext(this.ec);

Then to tidy up in terminate I use:

objectStoreCoordinator.dispose();

which invokes ERXEOAccessUtilities.closeDatabaseConnections() on itself

Whether or not I dispose of the ec as well, or call 
ERXEOAccessUtilities.closeDatabaseConnections() on the osc myself, I still get 
only one of the database connections dropped.

Re: ERXObjectStoreCoordinator dispose not releasing database connection?

[John Pollard]

I see that constructing ERXObjectStoreCoordinator(true) is another way to work 
around the issue of closing the db connection.
However, I still get two connections created and only one closed when disposed.

ERXObjectStoreCoordinator dispose not releasing database connection?

[John Pollard]

Hi List,

I have noticed that the database connections (seen using "show processlist" 
within mysql) are not being released.
I create my own ERXObjectStoreCoordinator and this results in two new mysql 
connections appearing.
When later I call dispose() on that ERXObjectStoreCoordinator, the database 
connections are not being freed up.
The dispose() call is in a Session.terminate() method, called after 
super.terminate().

Thanks for any thoughts on this.

Using type="image" on WOSubmitButton

[John Pollard]

Hi List,

I am displaying a button with my own image from a webserver image resource file 
by setting type="image" and src="path/to/file.jpg" on WOSubmitButton.

If I set the src attribute, it then gets mangled at some stage to turn it into 
a WO type of path, which fails with ...wodata=ERROR_NOT_FOUND...

I can fix this by using:

otherTagString = "src=\"path.\""

but is there a nicer way to specify the src path of my own choosing, without 
WOSubmitButton trying to turn it into a WO style of resource path?

Thanks

A couple. One has a Deny delete rule. The other is a many-many and has a 
Nullify delete rule, but the target object type, Transaction, is never deleted 
so these shouldn't come into play.

I grepped out all my cascade rules in the model plist files and couldn't see 
any that I could suspect of this crime.
If I work out what was triggering it, I will report back on this thread, but 
for now, I am ok with my workaround, many thanks.

Re: validateXXX not called on a relationship set to null

[John Pollard]

Chuck,

Ok, will put a trap in the setXXX method and see if that catches it if it 
happens again.

I am not quite clear on what you mean about checking relationships (plural) to 
this entity in the model.
My base object is Transaction
My to-one related object is Organisation
This relationship does have a Delete Rule of Nullify. I understood this to mean 
that if the related Organisation is deleted, we will be left pointing to null. 
That could explain it, though I am certain that the related object was never 
deleted.
I have in any case set it to Deny instead, which I take to mean disallow the 
deletion of the related object while I am pointing at it.

With Nullify delete rules, would the setXXX get called, but the validateXXX not 
called?

Thanks
John

Ok thanks. For a new object where the relationship is null (not set), the 
validateXXX does get called to check the null (good) and no call is made to 
setXXX or takeStoredValueForKey (makes sense).

The first sentence applies to when the relationship is set to something, when 
it does get called.
The second sentence applies to the problem scenario I have, where the 
relationship is being nullified having previously been set to something, but 
with no call to validateXXX prior to the sql hitting the database setting the 
relationship to null.
Perhaps Chuck has sniffed it out with the Nullify relationship rule, will reply 
to his post separately.

I do have validateForSave() which is calling super. But in my problem scenario, 
the relationship is changing to null without any validateXXX.

I don't yet know whether setXXX is called in my problem scenario (as I don't 
know how to replicate the problem scenario). I will add logging so

validateXXX not called on a relationship set to null

[John Pollard]

Hi List,

I am trying to pin down where a to-one relationship is getting set to null 
inappropriately.

I added validateMyRelationship() to trap and throw and this is triggered ok 
when the base object is created / updated.

However, it wasn't called when the relationship was set to null and hence the 
update proceeded, bypassing my trap.

Does the above scenario ring any bells; why isn't validateMyRelationship() 
called when I can see the update request to the database follows.

I can't set the relationship to mandatory as in some circumstances null is 
valid, though it should never change to null after it has been set.

Thanks
John

I guess ERXOptGroupPopupButton ought to be ETXBetterPopUpButton and allow group 
to be optional instead of required, then the other goodies can apply to a 
select without optgroups. I took a copy and did that.

Chuck (or anyone),
I see you added an itemDisabled binding to ERXOptGroupPopupButton.
Is there a way currently to disable items on non optgroup select popups? I 
couldn't see an ERXPopupButton for example, though I do see a PopupButton class 
in ERXPatcher.

ERXOptGroupPopupButton

[John Pollard]

Hi List,

I need to implement a  with  to give more structured popup 
selections like 
http://www.w3schools.com/TAGS/tryit.asp?filename=tryhtml_optgroup

I see Wonder has ERXOptGroupPopupButton but that it is in package 
com.webobjects.appserver._private;
which doesn't sound very welcoming. I note the comments say it is put together 
as a "quick hack".

Thanks for any insight in using it, seems a pity to reinvent the wheel.

in server exception strings

[John Pollard]

Hi List,

For deny delete rules, exception messages contain embedded html formatting, for 
example:

Cannot delete this Organisation. You should first delete items in its 
Blah Blahs Related Objects

As I present these in a Java Client window, rather than a browser, they look 
odd. Is there a quick work-around to not have the html formatting in error 
messages.

Many thanks,

Re: Wonder and Java Client

[John Pollard]

John/David, many thanks for your responses. On reflection with what you have 
said, I will probably leave well alone on the client side for now and keep to 
vanilla WO. There have always been JC bugs, though workarounds always possible 
and I find it very flexible and effective, using a Swing interface 
(JFormDesigner is great). I am sure new technologies are finally overtaking 
WO/JC but I still feel there is life in the old dog yet!

Wonder and Java Client

[John Pollard]

Has anyone used any Wonder frameworks in a Java Client application?
I have a long-standing JC app which uses Wonder on the server side, but not on 
the client side; what if anything from Wonder might be useful on the client?

These are the WO jars the client uses at present:

Intermittent hostname null in URL

[John Pollard]

Every now and then when running a Wonder-based WO app in development with 
auto-open browser, the app URL comes up as http://null... instead of my local 
machine name http://mymac.local/...
If I manually change the null to mymac.local all is well
I thought I had seen an article on this topic but can't find it now. Anyone 
else had this? It can work, stop working and start working again without any 
intervention from me.

Re: html5 input in a form "required"

[John Pollard]

I am certainly in debt to the community, but I suspect I would hinder more than 
help.
I can see er.extensions.components._private.ERXWOTextField which I understand 
automatically replaces the webobjects WOTextField class... is this what would 
need updating? I can't say I would be confident to do so. All components I have 
worked with have an html file and wod etc. 

I have also noticed that Wonder also has ERXWOInput derived from WOInput. Then 
ERXWOTelField and friends hang off WOInput. I might have expected these to 
derive from ERXWOTextField...but that may just illustrate my lack of 
understanding.

I should have said, when I do this:


  

the generated HTML comes out as required="e", apparently picking up the last 
parameter that did have a value.

html5 input in a form "required"

[John Pollard]

Can WOTextField or something similar handle the "required" in:



i.e. telling the browser that a field is required, it has not value assigned to 
it

I couldn't see a Wonder way for this.

componentActionURL ok to use for link href?

[John Pollard]

Is it ok to use the WOContext.componentActionURL() to get an href for 
navigating back to?
More explicitly, I am using a Dialog page in jQuery Mobile as an error 
reporting mechanism and I want the "Continue" button in the error dialog to 
know where to return to. So I pass in an href which is then used on the return 
link button in the dialog. It appears to work ok, but am I abusing the system?
Thanks

Conditional around opening part of another component only?

[John Pollard]

Is there any way to conditionally determine the opening html for a component 
only, not the whole thing?:


   


  

  ... bunch of html that applies to both the above conditions


Trying it, I can't, I am told that the   at the top is 
missing its closing tag, so presumably it has to be complete within the if 
clause.

My only solution seems to be to take the "  ... bunch of html that applies to 
both the above conditions" and put it into a different component, but that is a 
pain because that html invokes many methods from this component.

It feels like it would be nice to turn chunks of html into local 
html-only-components, that are part of the same WOComponent, but can be 
referenced more than once.

Re: Private coding comments in WO .html files

[John Pollard]

Now I see that there is a WOIncludeCommentsInResponse which I have as false
Some comments are stripped out, others not.
For example a code block:

  

has been fully expanded in the return page, still enclosed in the comments

Is this kind of block-commenting out of code not supported?

Private coding comments in WO .html files

[John Pollard]

Hi List,

What is the best way to add comments to a WO html file that are kept private; 
i.e. please strip out server side when dynamically building the page.
If I use  then my notes get faithfully replicated to the world of 
course which I don't want.
I have this ridiculous situation of not wanting to comment my html because it 
will pollute the final page content.

Problem solved, nothing to do with WebObjects.

Mobile to full site page, not refreshed until browser refresh

[John Pollard]

Hi list,

I have a site that will display in mobile / full site mode: www.team-picker.com
Click the "Mobile site" link next to the 4th tick down to see the mobile 
version.
Then click the Full Site button at the bottom left of the mobile page view.
This is where I have a problem, on returning to the full site view, the layout 
is corrupt. Viewing the page source, somehow the mobile elements of the mobile 
page have been retained. However, if you now Refresh your browser, the page is 
corrected.
How can I force the Full Site link to display the original page completely? It 
is currently a component action, but could equally be a direct action (doesn't 
help).

Note that if you view on a mobile phone first, the mobile page is presented by 
default. The same problem is seen there after clicking the Full Site button the 
full view is messed up and is fixed by a refresh within the mobile browser.

The state of Application.setPageRefreshOnBacktrackEnabled() does not make a 
difference.

What can the browser refresh be doing that my link to the page doesn't cause to 
happen in the first place?

Is it something odd with jQueryMobile perhaps which is used on the mobile page 
via ERQMHtmlTemplate, somehow causing the mobilification to persist for a 
further page request.

Thanks
John

Re: foreach: list must not be a constant

[John Pollard]

Many thanks, that fixed it, I had:

component.inlineBindingPrefix=[
component.inlineBindingSuffix=]
component.wellFormedTemplateRequired=true

Though using $ as the binding did actually work, even given the error showing.

Also my previous note about using an NSMutableArray was a red herring, the 
error message popped up again later.

Any pointers to best resources for learning the wognl way would be gladly 
received. I have found the list of wo: shortcuts in Eclipse, Preferences, 
WOLips, Inline Binding Shortcuts

Re: foreach: list must not be a constant

[John Pollard]

So changing getPlayerGroups to return an NSMutableArray fixed it, though why 
does foreach require a mutable array?
Is there any documentation that covers all the inline bindings and their 
arguments?
Many thanks
John
