I’m afraid I have to disagree. And the ability to alter the properties of the 
@Autowired object based on the environmental settings is indeed one of the 
strengths of the method. Among other things, it makes setting up testing in a 
continuous integration environment for example much easier.

Not really. If you know where to look and have sufficient understanding of the 
process, it’s not a big problem in my humble opinion. Of course there is a 
learning curve, especially with Spring and that can get a little frustrating.

As I mentioned above, it depends how you set things up and how well you 
understand the process. In the beginning of course I ran into these troubles, 
but once you understand how it works it’s not really that complicated. And 
again, it makes certain things a lot easier to set up. Plus it really makes for 
cleaner code (in terms of architectural concerns as well as readability). You 
won’t have to look all over the place to check if someone set the object up in 
some non standard way. If you needed specific properties on an object set, you 
can control that with DI just as well and it’s all in once place.

I wouldn’t try to bend the argument that far.

It also enabled us to control the class loading process which in some instances 
has been the only way to fix certain problems. It is used quite extensively in 
Wonder, if not mistaken. If not for this form of ‘DI’ (although I wouldn’t call 
it that), a lot of things would have been impossible to do.

Well, I can understand the resistance but frankly can’t second most of the

Absolutely. Proper DI facilities make things a lot easier to test. And the code 
much cleaner. Wouldn’t it be nice to have something like

@Autowired
EOEditingContext editingContext;

instead of 

EOEditingContext editingContext = ERXEC.newEditingContext()

perhaps even with some rule based setup, aka: D2W meets DI? 

Just thinking out loud.

Sorry, not being able to help. On the lookout myself, but not in Southern 
Germany. I feel your pain, though. WO jobs are hard to come by these days. 
However: once you get to know the Swing/Hibernate stuff, it isn’t half bad. If 
you employ clean architecture, good coding style and separation of concerns 
etc., you can have fun writing Swing/Hibernate code, too. I really like the IoC 
pattern as well, something that might be worth having in WO.

How to build ERRest response for NSDictionary?

[Jürgen Simon]

Hi,

I’m having some trouble implementing a simple function with ERRest. I have a 
method I wish to return a serialized NSDictionary from, not a serialized 
EOObject. Is that possible? The method could look something like this:

@GET
@Path(“/somepath/{id:Integer}/dailyReport)
public WOActionResults dailyReport(@PathParam(“id) Integer id)
{
NSDictionaryString,Object report = getDailyReport();

???
}

How would I go about building a response for this? Or do I need to implement 
another controller not inheriting from ERXRouteController for this?

WebObjects-Projects?

[Jürgen Simon]

Hello,

this is not a technical inquiry, more a temperature check on the 
business side of WebObjects. It is my impression that at least in 
Germany, after the 2008/2009 crisis the market for WebObjects-projects 
has really been down a lot. I have been looking hi and lo for 
opportunities to work with WO again, but apart from self-initiated 
projects there was nothing going on.


Is this perception limited to Germany or is it even just me? Are there 
any project marketplaces for WO that I am not aware of? How much of a 
future would you guys think WO really has?


Kind Regards,
Jürgen

Re: Immortal… ehm, frozen instances.

[Simon]

if we have this kind of issue the first thing we do is log out session
creation and check the stack traces. stick something like this in your
session constructor then check the output:

public Session() {
super();

StringWriter stringWriter = new StringWriter();

 PrintWriter printWriter = new PrintWriter(stringWriter);

 (new Throwable()).printStackTrace(printWriter);

 String trace = stringWriter.toString();  log this somewhere that you
can get easy access to

}

Re: Storing a user in a cookie

[Simon J Oliver (sjoliver)]

I think that first you have to think seriously if you really want to do this. 
There are two problems to guard against - making up tokens, and re-using other 
people's. Encryption might fix the first, but not the second. 

If you do REALLY want to do it,  you have to basically emulate a session ID, 
and store that in the database or in a file or something, and then look it up - 
with some sort of expiry period built in. You can generate the tokens with a 
hash function, it doesn't need to be reversible encryption.

If there is no expiry mechanism then anyone who has access to your token (e.g., 
from sniffing network traffic) from the cookie can masquerade as that user at 
any time (years later even), bypassing authentication, and you have no way to 
stop them short of invalidating the user id.

Session id's are always a bit of a trade off security wise, but you need some 
way to check that the return of the user is plausible and not just accept any 
connection that knows the magic words.

Yes I think OAuth could potentially work, although you'd probably want some 
sort of local session management /caching anyway to avoid the need to validate 
every request with the identity provider. OAuth has the advantage at least over 
Pascal's original scheme that it provides an form of expiry/invalidation

Depending on how long you want the tokens to live and/or how sensitive the data

It really all depends on you, your users and your data... I can't imagine many 
circumstances where just re-locking the door to fix a confidentiality/integrity

Yes I think OAuth could potentially work, although you'd probably want some 
sort of local session management /caching anyway to avoid the need to validate 
every request with the identity provider. OAuth has the advantage at least over 
Pascal's original scheme that it provides an form of expiry/invalidation 
mechanism that allows a token to be repudiated if needed.

Depending on how long you want the tokens to live and/or how sensitive the data 
is, you'd probably want to ensure that your app was served solely over SSH to 
minimize the risk of token theft.

Re: Immortal sessions in production

[Simon]

stick this in your session constructor, it will log out whenever a
session is created. then you can start figuring out where you are
creating a session outside the RR loop which is the normal culprit...

StringWriter stringWriter = new StringWriter();
PrintWriter printWriter = new PrintWriter(stringWriter);
(new Throwable()).printStackTrace(printWriter);
String trace = stringWriter.toString();
log.debug(Session count =  + 
application().activeSessionsCount());

ClickEventLogger2.getLogger().fatal(ClickEventCode.E00129, Session
Created:\n\n  + trace,
this.getClass().getSimpleName());

hmmm, you'll have to replace the ClickEventLogger2 line because
that's our logging mechanism. you could log.fatal it and set up an
email appender in log4j.

 Some instances go out of memory and they hang there.

 Hi All -
 Wondering if someone can throw me some ideas on solving what looks like an

 - Start up 1 instance in java monitor.
 - User lands on sessionless login page. No sessions.
 - User logs in. 1 session.
 - User logs out. 0 sessions.
 - User logs in. 1 session.
 - User does nothing. Session times out. 0 sessions.
 All looks good. However, we get to the end of the day and the instance has
 376 active sessions. But I know for this particular app there are only 6
 users, because they are all sitting next door :-) Also, If i now leave this
 instance overnight none of those active sessions will go away.
 So what could be going on ? Something appears to be creating immortal
 sessions, but forced session termination (by the user logging out) and
 session expiration seem to be behaving themselves.

 If the users don't notice any problems, my money would be on an exception
 thrown from your Session.terminate().  Also check the sleep() method to
 ensure it can never throw.
 I have seen a related problem where two requests come in for the same
 session (user double clicks, Ajax etc), and the first calls terminate() on
 the session.  The second thread is stuck and the app can't gracefully shut
 down.  IIRC, you would see zero sessions in this case.  The fix for this
 is to not call terminate() and instead set the session timeout to a small
 number of seconds

Re: Wonder apps under AWS ELB with sticky sessions, autoscaling EC2 instances.

[Simon]

we had problems with elb, wo and sticky sessions. we now run zeus load
balancers on ec2.

we never got to the bottom of it, just randomly the session would seem
to loose it's stickyness, head off to another ec2 instance, new
session and login page.

i suspected it was due to switching between http and https and we
intend to re-trial elb in a few months time because we are moving all
of our apps to full-time https and secure cookies.

sorry, not much help i know, but just a heads up that we did have
problems. i'd be interested in knowing how you get on...

 Hello list!

 I've been working on a number of wonder applications the last year at my
 9-5, all of which we have deployed to AWS in various development and
 staging/QA states. For the production environment of the main application,
 we are looking at a deployment setup quite similar to this reference
 diagram:

 http://d36cz9buwru1tt.cloudfront.net/architecturecenter/AWS_ac_ra_web_01.pdf

 (from http://aws.amazon.com/architecture/)

 It's important to the company to ensure we can run smoothly across
 multiple Availability Zones of a Region, so the diagram represents the 3
 (+1) tier application setup we are looking for.

 We're really happy with the approach we've taken so far, and the
 ELB-session-stickiness and autoscaling of the application tiers in each AZ
 is something we are currently evaluating.

 Ignoring CloudFront and Route 53 for a moment, we're interested in setting
 up the ELB with sticky sessions/session affinity, apache on each AZ, and a
 number of application VMs on each AZ, each one of course running a number
 of WO instances. The persistence tier is absolutely fine and accounted for
 in both AZs.



 So two quick questions:

 1. Has anyone had any experience with ELB and sticky sessions with regards
 to WO, WOMonitor, and wotaskd? If so, are there any gotchas or hurdles you
 foresee me coming across? Any tips for smooth sailing?

 Tied (or apposed really) to this is the concept of distributed session
 storage, which we are also considering, so I'm looking forward to your
 WOWODC session, Ramsey!

 2. Currently we're looking at manual horizontal scaling of the application
 tiers in each AZ, but it would be great to design/have a solution for
 triggered horizontal EC2 VM scaling with respect to WO. This would
 presumably require updating the WOMonitor and wotaskd. Again, any one with
 previous experience wanting to warn me off/enthusiastically give me hope?




 Any knowledge in this area would be greatly appreciated!

 Cheers,

 and see you all at WOWODC.

Problem with download link in 'appendToResponse'

[Juergen Lorenz Simon]

Hi,

I'm trying to generate some file content on the fly and return it when the user 
clicks a link. I'm doing this in a D2W context, the component is a propoerty 
level component. I had some success by overwriting appendToResponse like so:

public void appendToResponse(com.webobjects.appserver.WOResponse response, 
WOContext context) 
{
if ( shouldDownloadFile )
{
String fileName = generated.properties;
String contentType = text/ascii;
response.setHeader( contentType + ; name=\ + fileName + \, Content-Type 
); 
response.setHeader( 
attachment; filename=\ + fileName + \, Content-Disposition);
String content = this.configuration();
response.setContent( content );
}
else
{
super.appendToResponse( response, context );
}
}

The flag 'shouldDownloadFile' is set to true when the link contained in the 
component is clicked (normal action binding).

However, instead of only the generated content, I also get some other generated 
HTML in the file. Does somebody know what the problem is?

Kind Regards,
J.L.Simon

It looks we have a problem with JavaMonitor and wotask, that had to be fixed.

I have seen this Problem now on several Machines, and found the problem, but

Maybe the only way is to fix the Apps Javacode itself...

Test Machine was OS X Lion  OS X SnowLeopard



What is going on:

The correctway : If the Machine starts

* LaunchD starts the Database

* LaunchD start JavaMonitor  wotask

* wotask will start the Instances

* Everybody is Happy



The Problem only appears if the Boot disk is a SSD Drive.

* LaunchD starts the Database

* LaunchD start JavaMonitor  wotask

BUT, JavaMonitor and wotask Launches and try to get the Network Interface for 
making work,
the OS Networking isn't setup at that time. The Boot was to fast. Both Apps try 
for several time,
and give up. But running. a Zombi process

* wotask can't start the Instances

The only way after the Launch is to go to Activity Monitor to kill both 
processes, LaunchD will boot
both again and everybody is happy.



1. Fix 1 : LaunchD Script - I have no idea if that is possible to say launch 
at Boot but delayed or so

2. Fix 2 : In the javacode after retry the App and can't get a Connection kill 
itself, and let launchD boot it again..

Re: JavaMonitor wotask SSD Problem.

[Simon J Oliver (sjoliver)]

I was just diffing the application launch scripts for a default 
wotaskd/javamonitor that I had lying around (not exactly sure which version - 
probably from 5.3.x) and the Wonder versions - i.e., wotaskd.woa/wotaskd and 
JavaMonitor.woa/JavaMonitor (not the launchd code).

In both cases the stock versions include the following code right before the 
application is launched - and which is not present in the Wonder versions of 
the apps (or in my own built apps):

# Verify network services are intialized before starting
#
echo Checking network services
if [ ${PLATFORM_TYPE} = Darwin ]
then
 /usr/sbin/ipconfig waitall
fi
#

It seems that Apple recognized this problem, and took steps to customize each 
of these 'likely to be launched boot time' applications' boot scripts to deal 
with it.

Is there a way to build the Wonder versions to include modified launch scripts 
by default? Alternatively, I think you could go with my earlier idea of a 
dedicated launchd task to wait for the interfaces at that point, and then bring 
up wotaskd, Monitor and Apache once the network is ready.

I recall modifying the app.woa/app startup script at the end.

Basically, wotaskd should start first (it will start your app), then after it 
is running javamonitor should start. The tail end of my wotaskd.woa/wotaskd is 
like:

#
# Launch the application.
#
# gsb 6/9/2010
# wait untill things boot all the way up
/usr/sbin/ipconfig waitall
#extra time for db
/bin/sleep 100

# Launch the application.

echo gb fixed? Launching ${SCRIPT_NAME}.woa ...
echo Launching ${SCRIPT_NAME}.woa ...

com.webobjects._bootstrap.WOBootstrap ${COMMAND_LINE_ARGS}
eval exec ${JAVA_EXECUTABLE} ${JAVA_EXECUTABLE_ARGS} -classpath WOBootstrap.jar 
com.webobjects._bootstrap.WOBootstrap ${COMMAND_LINE_ARGS}


And for my  JavaMonitor.woa/JavaMonitor:

# gsb 6/9/2010
# wait untill things boot all the way up
/usr/sbin/ipconfig waitall
#extra time for db
/bin/sleep 240

#
# Launch the application.
#

#
# Launch the application.
#
echo Launching ${SCRIPT_NAME}.woa ...

echo ${JAVA_EXECUTABLE} ${JAVA_EXECUTABLE_ARGS} -classpath WOBootstrap.jar 
com.webobjects._bootstrap.WOBootstrap ${COMMAND_LINE_ARGS}
eval exec ${JAVA_EXECUTABLE} ${JAVA_EXECUTABLE_ARGS} -classpath WOBootstrap.jar 
com.webobjects._bootstrap.WOBootstrap ${COMMAND_LINE_ARGS}


So I had javamonitor trying to restart wotaskd which was waiting for things to 
happen. This did not allow proper startup. With the wait and extra time for 
javamonitor reboots work properly.

I think the apple wo 5.4.3 startups had some waiting; this is the Wonder 
versions I had to modify.

A wait maybe should be added to the Wonder wotaskd and JavaMonitor startup 
scripts.

I could be wrong, of course.

Re: Instances don't show up in Monitor and URLs do not work.

[Simon J Oliver (sjoliver)]

Dennis -

In my experience FQDN is definitely the way to go - make sure your apps, 
monitor, and wotaskd all have the exact same thing. Run nslookup or similar at 
the command line to make sure the name resolves to the IP address of the NIC on 
the box, and the IP address resolves back to the name that you're using as the 
WOHost parameter. A handful of additional thoughts:

1)  have you made sure that your adaptor config correctly has the correct 
hostnames and ports for the wotaskd(s) it needs to know about? What does the 
adaptor config page tell you about what apache thinks the world looks like? 
(Apologies if you already covered that... I just caught the last couple of 
posts).

2) have you checked your launchd boot scripts for wotaskd and monitor (if 
that's how you are launching them) to make sure that you don't have alternative 
WOHost entries in there as command line arguments? (if they aren't there 
already, maybe try adding them there, to make sure that the values you want are 
getting picked up).

3) I had an issue today (and I noticed someone else post something similar 
recently in connection with SSD boot drives) that wotaskd and womonitor were 
binding to the loopback address (only) not the ones I was asking them to - 
apparently because the nics weren't properly initialized at the time the apps 
were starting up at boot time.

For me, killing the two java processes manually and allowing launchd to restart 
them fixed the problem. They came back up on the correct interfaces, and the 
IP's matched what they were expecting, and all was good.  Have you tried 
manually killing/restarting the processes after the machine has booted up?

4) FWIW, I generally specify the WOHost for my apps as an additional command 
line argument in the app config in WOMonitor, rather than in the properties 
file. You may want to try that.



I know from experience how frustrating the dance is to get things to work 
right, but it's generally always worked out for me, and I am deploying apps on 
Lion Server just fine, with the Wonder versions of monitor and wotaskd.

Regards,

Simon

Yes DNS works correctly with 'changeip -checkhostname'; put full host names in

worked for us in the past.

Re: JavaMonitor wotask SSD Problem.

[Simon J Oliver (sjoliver)]

I saw this problem (or something very much like it) today on a 2008 Mac Pro 
running Leopard, and not an SSD in sight... so while SSD's make it worse, it 
can happen in other circumstances.

In what seems to me like an odd decision, given Apple's dependency on it (and 
hyping of it) launchd doesn't enforce dependencies. The best solution is 
probably that rather than launching wotaskd and womonitor directly from the 
launchd plist, instead call a shell script that first checks that the NICs are 
up, and then launches wotaskd and monitor for you.

That shell script can use 'ipconfig waitall' to block until the NICs are up. I 
haven't done it for WO yet, but I use something similar to set up static routes 
on my boxes at launch time. Based on that chnk of code (which started life as 
http://www.macosxhints.com/article.php?story=20060329085850170 , in the routing 
context) , I *think* that something like this should work to start them up:


#!/bin/sh
# We need to trap on TERM signals, according to Apple's launchd docs:
trap 'exit 1' 15

# Issue a log message so we know when we started
syslog -s -l 1 WOMonitor_start: starting WOMonitor...

# Use the ipconfig waitall command to wait for all the
# interfaces to come up:
ipconfig waitall

# This is where we start WOMonitor
put your WOMonitor startup command here with any command line args

# Sleep for a while so Launchd won't think we never ran
sleep 10

# Issue a log message so we'll know when we finished
syslog -s -l 1 WOMonitor_start: Done.

# Exit with a clean status
exit 0


You should be able to launch that from launchd, instead of womonitor itself.

Regards,

Simon

Re: Instances don't show up in Monitor and URLs do not work.

[Simon J Oliver (sjoliver)]

Dennis -

In your apache config file you should be including a line similar to:


Include /System/Library/WebObjects/Adaptors/Apache/apache.conf


In that file that is referenced is where the apache adaptor gets configured: 
that's where you tell apache where to find the wotaskd's its talking to.

Take a look at the WebObjectsConfig line in there, to see what it's trying to 
talk to. It should be something like:

WebObjectsConfig http://hostname:1085  10

(I have localhost in there, and it seems to work - I'd try the FQDN in your 
case).

As explained in more detail in my previous response, this stuff gets set in the 
Apache WO config file which typically lives somewhere like:

/System/Library/WebObjects/Adaptors/Apache/apache.conf

That file also allows you to set an adaptor info password, so that you can see 
what apache thinks are the available apps via a url along the lines of:

http://webserver/cgi-bin/WebObjects/WOAdaptorInfo?user+password

(The apache.conf explains this).

If you look at that,you can see whether mod_webobjects is talking to your 
wotaskd. It sounds like it isn't.





2) have you checked your launchd boot scripts for wotaskd and monitor (if 
that's how you are launching them) to make sure that you don't have alternative 
WOHost entries in there as command line arguments? (if they aren't there 
already, maybe try adding them there, to make sure that the values you want are

Please see above, we set them in the Properties.

That's fine - my point was mostly just to double check that there isn't 
something set on the command line in the plist that's overriding what you think 
you have in the Properties.

However, it sounds like you're running into the SSD/NIC issue in the first 
instance. Manually restarting the processes *might* be fixing that bit - but 
then if I had to guess I'd say that the apache.conf file has a problem that 
stops mod_webobjects talkign to wotaskd , so you still get the 'The requested 
application was not found on this server' error.



3) I had an issue today (and I noticed someone else post something similar 
recently in connection with SSD boot drives) that wotaskd and womonitor were

Yes, that was us too; we only use SSDs for deployment. Restarting wotaskd and 
JavaMonitor still comes up with the famous The requested application was not 
found on this server.

Once you've restarted them, compare what the wotaskd/woconfig thinks the 
situation is, compared to what the WOAdaptorInfo page thinks is going on.  If 
the instances are running, and wotaskd sees them... then the focus should be on 
Apache, I think, as the source of your problems.



For me, killing the two java processes manually and allowing launchd to restart 
them fixed the problem.
Exactly but still; The requested application was not found on this server.

They came back up on the correct interfaces, and the IP's matched what they

4) FWIW, I generally specify the WOHost for my apps as an additional command

Tried that, it just showed up twice per instance that way, in the ps -ax | grep 
java; and did not help. Apparently, monitor added it already



I know from experience how frustrating the dance is to get things to work 
right, but it's generally always worked out for me, and I am deploying apps on 
Lion Server just fine, with the Wonder versions of monitor and wotaskd.
We also got the newest:

_appserver  _appserveradm  337112 20 Feb 17:44 mod_WebObjects.so


That seems to be the version I'm using on Lion - same size at least.



So why does this still not work; maybe I am missing something else?

Thanks for any further help

Glad to help; I don't know that it's Lion per se causing the start-up thing. My

today with Leopard :-)

If you try the 'ipconfig waitall' thing, let me know if it solves the problem.

Dennis -

In your apache config file you should be including a line similar to:


Include /System/Library/WebObjects/Adaptors/Apache/apache.conf


In that file that is referenced is where the apache adaptor gets configured: 
that's where you tell apache where to find the wotaskd's its talking to.

Take a look at the WebObjectsConfig line in there, to see what it's trying to 
talk to. It should be something like:

WebObjectsConfig http://http:/hostname:1085  10

(I have localhost in there, and it seems to work - I'd try the FQDN in your 
case).

Re: Finding WO people for startups (cult of the dead)

[Simon]

 renderContentOn: html

  html table: [
   html
    tableRow: [
     html tableData: [html text: 'Table entry']];
    tableRow: [
     html tableData: [html text: 'Table entry']]].

 Look foreign? Perhaps but it's worth getting your feet wet and kicking these 
 ideas around. I've seen many things and this is the first set of tools and 
 processes that make me feel good. Like it is equivalent and perhaps better 
 than WO. It's brain dead easy to install and there are a number of tutorials 
 out there.

 OK, I see what you are talking about now.  I am not sure if that is a win for 
 me.  I have this designer that I often work with and he is able to take an 
 Eclipse project and edit the .HTML files to make design changes.  He does not 
 touch the WOD or the Java.  This has been working pretty well for us.  
 Switching to Seaside would mean that we would have to take the initial 
 designs, convert them into code, and have the developers maintain them 
 through the inevitable changes.  I'd have to see how much time the rest of it 
 would save me.

totally agree. this is not a plus for us either. our UI people play
with html (we don't do wod's, 100% inline bindings), and our java
people play with Java.

the thought that our java team would have the UI team on their backs
all day saying er, can you change that table, tr and td mess
you're pumping out for a list please (like i told you last time)
fills me with fear!

even if you keep your UI people to tidy up with css, surely they are
going to be nagging java engineers to get the correct id's and classes
pegged to the html the java code is pumping out ? it seems this is
only a benefit if your java people actually look after the whole UI
piece as well - and i've yet to find a java engineer that has style.
no offence intended :-)

 So, does anyone have seen a tool that exposes entities and attributes out of

Re: Occasional hang loading a particular large page

[Simon]

 Have you tried using ERXBatchFetching stuff?

 I use ERXBatchingDisplayGroup for large pages and it has worked well.

 No I haven't. When it works, the page loads pretty quickly, faster than I 
 would have expected. If I can just track down what causes the occasional hang 
 and fix that, then everyone will be happy.

we **always** use ERXBatchingDisplayGroup - doesn't matter if we're
intend to fetch 5 objects or 50,000.

we just assume that one day that someone will fetch 500,000 and hence
we might as well get it right from the start...

 the general idea behind the OWASP approach is to provide encoders that
 will make your user input strings safe so that they wont activate some
 malicious scripting. The other thing it provides is the ability to define
 parameter specific whitelists that can be validated using REGEX
 expressions to ensure that the values that are provided are within an
 acceptable domain range. Of course it is very to come up with an unsafe
 REGEX expression that allows all sorts of bad behavior to come thru.

 We use both capabilities in our application. The REGEX portion is nice
 because it allows you perform good data validation which is essential to
 avoid cross site scripting errors.

 The encoders provide the ability to properly encode strings for various
 uses like SQL, HTML, URLs, CSS, javascripts, LDAP

 In your example below, the onfocus parameter would use the ESAPI
 encodeForJavascript() to convert the write(1) autofocus into HTML encoded
 text that would not be executable.

 In order to remove unwanted and malicious code from the submitted HTML

Re: WebObjects vulnerabilities?

here you go, i just found a WO powered site on the web that will kindly
demonstrate the issue. it is sensitive to encoding, but this link should
work in chrome and firefox (not got any IE's nearby to test):

https://secure.kagi.com/cgi-bin/WebObjects/PQ?wosid=3D%22%3E%3Cscript%3Ealert%281%29%3C/scri=pt%3E

the issue is of course that rather than an alert, someone injects a
location.href= that points to a fake site that has an identical login page
to yours, and hence you customers unwittingly hand over your login
details

Re: WebObjects vulnerabilities?

[Simon]

nice one! yeah, that works. whacks in a new text field into your page
and gives it focus :-)

https://secure.kagi.com/cgi-bin/WebObjects/PQ?wosid=3D%22%3E%3Cinput%20onfocus=write(1)%20autofocus%3E

the wosid parameter in a webobjects url is a gaping backdoor for cross
site scripting (whether you are storing session id's in urls or not).
the patch we are running in ERXRequest checks for a wosid parameter
coming in on every request and makes sure it contains no dodgy looking
characters. if it finds them, it throws the whole session key away.
it's kinda like what mike suggested, but allows you to support
non-cookie sessions.

 WO-Applications are indeed vulnerable to cross-site-scripting if end-users

 An example would be an Online-HTML-editor which allows users to edit

 In order to remove unwanted and malicious code from the submitted HTML and 
 avoid cross-site-Scripting issues one has to filter the submitted content on 
 server side.
 For this task I have found AntiSamy to be a useful solution

Re: Help with ERAttachments

[Simon]

hi daniel -

we had exactly the same issue when we first set up ERAttachment. we worked
around it by having all of our relationships to the specific subclasses.

i never got time to figure out what it was doing but i'd guess the
inheritance is getting mixed up somewhere - it's as if ERAttachment isn't
abstract and hence it's trying to fetch an EO with pk = 5 and storageType =
. maybe if you pump out the raw sql in your logs you could post the sql
it's actually using to try and fetch the attachment...?

Re: NSNotificationCenter

[Simon]

we do a lot of this type of thing using NSNotifications. the key is to
use pass in the user as GID, not an EO, then use a thread execution
pool to do your stuff. i've pasted below some sample code - this is a
class that listens for a new ReportJob, then actually creates the
report. I've ripped out all the code that is specific to the task but
you should be able to figure the the general concept from what is
left.


public class ClickReportJob {

public static class Queue extends Object {

private static NSMutableDictionaryEOGlobalID,
FutureTaskReportJobThread _queue;


public static void addToQueue(FutureTaskReportJobThread ft,
EOGlobalID gid) {
getQueue().setObjectForKey(ft, gid);
}


public static NSMutableDictionaryEOGlobalID,
FutureTaskReportJobThread getQueue() {
if (_queue == null) {
_queue = new NSMutableDictionaryEOGlobalID, 
FutureTaskReportJobThread();
}
return _queue;
}

}

 Hello,
 Some customers asked us for adding some automatic per user notifications

 I'm looking at NSNotification/NSNotificationCenter for this purpouse but I'm
 wondering if the notification dispatching and processing is performed on the

Re: Amazon EC2 Image

[Simon]

 I haven't used those particular scripts, but eyeballing them they _seem_ to 
 be dependent on the pre-rolled appserver AMIs, also supplied by Simon.

nope. they are designed to be used with a scratch linux ami. we use
amazon linux. the ami id's are likely to be different because amazon
used to change them as they updated them. i don't think they do that
anymore.

but basically the scripts should work with any RHEL compatible linux distro.

simon

ps. the pre-rolled ami i put up some time ago should also be
considered defunct. i'll remove it from the wiki now...

Re: ps: database failures not rolling up to eof stack ??

[Simon]

  the repeatable situation that we see this happening is when we try and
 set a string value that is defined as width X in the model and DB to
 something greater than X.

 That should cause a validation error in EOF, not a string truncation error
 in the database.  Did you write that backwards?


hmmm, come to think of it, that does look the wrong way round...


  my guess is that we must somehow be disposing of the exception somewhere
 but i can't seem to figure it.
 
  any ideas ?

 If you are not catching and swallowing it in your code, my suspicions would
 like in the JDBC driver or in the EOF plugin for MySQL.  I have never seen
 EOF swallow exceptions originating from a failure to commit.


hokey cokey, i'll start poking around from the driver up. i suspect we've
introduced something daft somewhere that is slurping them up, but there is
nothing startlingly obvious. might have to dig out some books and remind
myself how exceptions float up through the stack :-p

thanks for the hint

[OT] Amazon AWS is now a level 1 PCI compliance service provider

[Simon]

following on from a thread a few months back regarding pci compliance and
amazon ec2...

AWS has achieved Level 1 PCI compliance and is now a validated PCI Service
Provider. This is a key designation that provides a means for merchants and
other service providers to become Payment Card Industry (PCI) certified
while storing, processing, and transmitting credit card information in AWS.
This validation also provides further clarity and assurance for customers
evaluating the breadth and strength of our security practices.

Re: x-webobjects-request-id lacking uniqueness?

[Simon]

i was thinking the same - alternatively:

- do whatever is you are doing in a background thread
- switch on concurrent request handling, as i presume that it is actually
the request that is blocking, not the DB as unless your are using something
like m$ access (eeek!) then i would imagine your DB can actually do more
than one thing at once
- if you are using m$ access, change it if you can, or resign if you can't
- re-work locking strategy to force an optimistic locking failure if more
than one update goes through - even if that involves sticking a dummy
attribute in that just increments with each transaction

what you are suggesting feels a bit like sticking some pedals on a car
because the engine keeps stalling - probably best to fix the engine :-)

  I have an app doing something superficially like web services which is
 sessionless and accessed via DirectActions.  Because of other activity in
 the database sometimes, database i/o can block for several minutes.  When
 this happens the Apache WebObjects adaptor's loadbalancing features come
 into play, and redirect the request it sent to an apparently unresponsive
 instance to a different instance, which may in turn block on database i/o.
  The caller's browser waits several minutes and then receives an no
 instance available page.  When the other activity in the database clears
 an, if the request caused a database update, that update can be applied
 multiple times because of each instance attempting to process the request.
  If the first update changes the database in a way that prevents the other
 updates from succeeding, they might report update failed, and if the
 database i/o hold up was only a few minutes, that page can be returned to
 the caller -- a page saying that the update failed, when in fact the update
 succeeded but the caller won't get to see that page.
 
  What I thought about doing, and have largely done, is announce and listen
 for activity via multicast datagrams.  If an instance receives a request via
 a direct action and I don't want it to be redirected via the load balancer,
 enough information is broadcast such that other instances waiting for
 requests will be able to tell that another instance should already be
 processing it, and then generate a response (without blocking on database
 i/o) to the effect that database congestion may be in progress, that their
 request is being processed, any database updates may or may not be committed
 but will be committed at most once.
 
  But what constitutes enough information?  The WebObjects adaptor adds a
 header x-webobjects-request-id (aka REQUEST_ID_HEADER, in config.h) to a
 received request before writing it to an instance (this header is not
 leaked back to the client) and this appears to be unique: 24 chars long
 corresponding to three hexstrings of 32-bit numbers, being the time at which
 some initialization code was called in the process (httpd), the process
 identifier (of httpd), and a unique sequence counter defended by a lock.
  The point at which this header is added means that a redirected request
 will have the same x-webobjects-request-id header.
 
  And so to the subject line of this message: x-webobjects-request-id
 lacking uniqueness?  Of those 24 chars, the first 16 are effectively fixed
 whenever httpd starts, and I appear to be seeing values being reused for the
 last 8.  I'd guess that either the shared memory or the locking isn't
 working as expected.
 
  Anybody else seeing this?

Re: datepicker on AMD problem

are you rendering the content inline ? we use ADP in AMD's quite a bit and

 Is there something more I am supposed to be doing to make the DatePicker

Re: [Wonder-disc] new wolips and wonder --

[Simon]

hi there -

i just booted an instance of ami-de91bbaa with a shiny new keypair and
logged right in with ec2-user.

ssh -i ec2.pem ec2-user@publicdns

are you booting via the amazon console  or command line ? i always use
the console.

there is a new version of the boot script too:

http://webobjects.s3.amazonaws.com/wo-install.sh

only a few minor tweaks, and the script now doesn't boot wo services -
it leaves you (or whatever calls this script) to do that in case you
have other tweaks to make before you want the services booting.

i've got a work-in-progress page on the wiki too, together with some
example scripts on how we are doing things. it's work in progress
because the example scripts don't quite work yet - an instance will
boot etc. but the AjaxExample apps don't run properly. i just need to
spend a couple of hours figuring out why not when i've got the time.
might be worth downloading the sample scripts and reading through them
if you are heading in this direction...

 As does the mime type of the resulting response.

 I'm kinda at a loss as to what the issue may be.

 I see some odd behavior with the AjaxExpansions when JavaMonitor is running 
 on a server. The images ToggleDown.png and ToggleRight.png are not 
 appearing. Looking at the resource protocol of Safari the images are listed 
 as 0 byte and a question mark though they are where WO should look for them 
 (the URL is correct). All other images are displayed correctly and the 
 files are not corrupted as Preview opens them and even dropping them into 
 the apache htdocs shows the right graphics in a browser.
 I enabled logging in JavaMonitor but neither in that log nor in the apache 
 log I can see any errors or hints. Running JavaMonitor in Eclipse the 
 images show up. Though it is unimportant for the operation of JavaMonitor I 
 am curious if anybody else sees the same behavior and why it fails.

      nextPage = pageWithName(Main.class);
      ERXRedirect redirect = pageWithName(ERXRedirect.class);
      redirect.setSecure(false);
      redirect.setComponent(nextPage);
      return redirect;

 but.. for a registration page I  don't want to create a session.. what can 
 i do?

 2) Ajax components need session? Because I've a ajax list product page 
 and a session is automatically created

 Thank you

 What I want to do is changing this code inside a direct action (which does

 return nextPage;
 to something equivalent where I can change the secure flag...
 If I understand correctly if I use ERXRedirect I have to use direct actions,
 so... I have to create a dummy direct action which simply redirect to the
 page I want, and than user ERXRedirect
 This is my code:
 ERXRedirect redirect = pageWithName(ERXRedirect.class);
 redirect.setUrl(context().directActionURLForActionNamed(UserAction/helpRedirect,
 new NSDictionaryString, Object(new Object[] {Boolean.TRUE}, new String[]
 {registration}),
 false,
 true));

 return redirect;
 public WOActionResults helpRedirectAction() {

 WOComponent nextPage = pageWithName(UtilitiesPage.class);
 NSArrayString dict = request().formValueKeys();
 for (String key: dict)
 nextPage.takeValueForKey(request().formValueForKey(key), key);
 return nextPage;

 }

 and in my utilities page:
 public void setRegistration(Object value) {
 if (value != null) {
 if (value.getClass().equals(String.class))
 this._registration = new BooleanHolder(Boolean.parseBoolean((String)value));
 else if (value.getClass().equals(Boolean.class))
 this._registration = new BooleanHolder((Boolean)value);
 }

 else
 _registration = null;
 }

 It seems to work, but is this really necessary?

 look at the source code to ERXRedirect, line 175:

 WOSession aSession = session();

 bingo. A session gets created.

 a quick scan through the code suggests that this only happens when
 handing a component to the redirect. Redirect to a DA or an explicit
 URL and you shouldn't get a session

 A session is always created if you use statefull components or form actions.

 The page needs to be all made with stateless components and the form must
 use direct actions.

 As for Ajax, well, you might have to rethink it:

 The submit buttons link to two Direct Actions.

Re: Ajax framework's future

[Simon]

 jQuery is the most likely future. It's on the task list, but nothing is 
 particularly driving it. At one point I thought about making a pluggable impl 
 but decided it wasn't worth the complexity for something that might only 
 change every 4 years. jQuery seems to have most of the mineshare at this 
 point and seems like a good choice. If I do it I'll probably make a new 
 framework and copy everything over so it doesn't break people that have big 
 investments in prototype.

+100

our UI people are always pointing out that jQuery has so much momentum
behind it, whereas prototypes seems to just be stagnating...

 I think it's just a matter of picking a horse. From my perspective, jQuery

but i guess picking any horse that is actually still trotting around

Re: WebObjects scalability question - WOSession?

[Simon J. Oliver]

I think it's also very much worth pointing out that client-side state has huge 
implications for security; as developers we basically should not trust anything 
that is supplied to us by the client.  For any non-trivial app that actually 
requires session state be stored, the chances are high that you don't want 
malicious users to be able to mess with the internals of their session.

 (Not that I'm doing any WO these days, but I still like to follow.)
 
 One thing that has always worried me about scalability is keeping the per 
 user application state on the server in WOSession. Knowing more about 
 REST now, this is very unrestful and not stateless, which means will not 
 scale.
 
 I don't see why something being unrestful and not stateless automatically 
 equates to not being able to scale. Perhaps you could explain.
 
 The problem is that once you get 1000s and millions of users you have the 
 problem of memory size storing all that session information in memory on the 
 server.
 
 As with any system, the number of concurrent users that can be handled on a 
 given server depends on both the application and the technology that it is 
 built on.  I will grant you that WO probably uses more memory per user than 
 many technologies.  But memory usage is only one part of the equation.
 
 
 Server must also manage all these sessions - clean them out every so often. 
 And (in middleware systems I worked on in the 80s) keep track of state 
 transitions with FSMs, etc.
 
 Yes you need session state, ie context, but it should be kept on the client, 
 which sends it along with each request. Thus user state is kept only on the 
 client which makes recoverability easier too, because if the server is 
 rebooted, client can continue oblivious to any problem.
 
 Yes, recoverability is a nice to have feature, but really how often is it 
 actually needed?  Restarts should be planned with the instances being set to 
 Refuse New Sessions so that there are no active sessions on a machine when it 
 is rebooted.  So recoverability is only strictly needed for accidental 
 restarts, kernel panics and such.
 
 The problem with keeping the WO state on the client is that WO keeps a LOT of 
 state (EO, changed attributes, page cache, etc).  You would need to have a 
 finely tuned way of getting that back and forth from the client, otherwise 
 performance would suffer mightily.

 A new example app was added to Wonder today : Movies. It's an app that Travis

 ERAttachment, ERTaggable, ERRest, ERChronic and inline bindings.

 Many thanks to Travis for his code!

 No, it just requires you to develop on an Apple-branded computer. It doesn't

 There doesn't seem to be a built version of wotaskd here:

 http://webobjects.mdimension.com/hudson/job/Wonder54/lastSuccessfulBuild/artifact/dist/wotaskd.woa.tar.gz

 There's one under the Wonder53 project.  Does anyone know why this is?

 This is killing me.  You don't have a recent copy of wotaskd.woa.tar.gz lying 
 around, do you?  Otherwise I'm going to have to try and build it locally I 
 suppose.

sorry paul, i don't.

this issue is killing me too because our auto-build's of new servers
download javamonitor and wotaskd from the mdimension build server...

i think we're going to break that dependency and build them ourselves
from now on. i guess we can drop the builds into our public webobjects
s3 bucket for anyone else to pluck off as they wish.

Re: Java apps not in new Mac App Store???

This is great news for java developers on the mac platform. Apples

 Hi Matthias,
 Where did the X11 come from? I don't see that in the emails you are copying 
 below.
 Also, as Rob Ross pointed out below, this ends up making MacOS X the same as 
 every other OS out there, you will have to download and install a JVM 
 yourself in future versions of OS X. Where to get a third-party JVM for Mac? 
 That's another question. Now that Apple isn't providing their own JVM and 
 they've opened OS X up for others, there should be a third-party, or even a 
 Sun/Oracle VM soon.
 There's a _lot_ of Java coders out there using Macs. It's a vacuum that isn't 
 going to last long.
 It does suck that Apple's own JVM is being deprecated, but it's not like 
 Microsoft has their own JVM either and Java seems to work just fine there.

 announcement.

 That these two announcements happen on the same day is very suspicious, and 
 it is hard not to think they are quite related.

 If your product needs Java you are now free to bundle/install a JVM
 with your product (or point customers at it) and the OS will support
 using it. Many folks have been asking for this capability. This is
 like most other operating systems. It is also similar to products that
 use things like Qt, they bundle it with their application.

 If you purchased a Mac to do Java development you can continue to use
 it for that by using a 3rd party JVM, etc.

 Apple isn't planning to continue their JVM port essentially but they
 aren't preventing others from doing so. It sucks but...

Re: WebObjects Community ideas on Google Moderator

[Simon]

 and our Wonder version is really heavy Documented. That makes it also hard 
 to give back Frameworks to the Community.

 That is unfortunate.

this is why the following idea on google moderator is so important:

We need a way to link the JavaDoc and the wiki together. It could be
special tags in the JavaDoc so that those tags are found, we
automatically create a page in the wiki with a link to the JavaDoc.

google translate could then sort it all out !

 @Axel Rauschmayer since SWT uses native widgets it does not run on X11,

 That's not true, Eclipse uses native cocoa widgets, so it is largely
 unaffected by this.  But it does rely on a few extensions to standard java
  provided by the mac version of the JVM, and these will have to be dealt
 with.  X11 will never be necessary to run an SWT app on mac.

Re: Replacing JavaMonitor and wotaskd with Wonder's ones

[Simon]

good point, although i think apple installers forgot all about wo a
few years back :-)

we've been using the wonder versions in production for the past 4
months and agree, it's super stable.

 Personnaly, I wouldn't change the versions in /System since Apple installers 
 might replace with their own versions. Apple don't like having non-Apple 
 stuff in /System and sometimes they disabled it in a OS X update.

 What I do in those situations :

 - Drag the builds from Wonder and put them in 
 /Library/WebObjects/JavaApplications
 - chown -R appserver:appserveradm /Library/WebObjects/JavaApplications
 - stop Apple versions of the deployment stuff
        - sudo launchctl stop com.apple.webobjects.JavaMonitor
        - sudo launchctl stop com.apple.webobjects.wotaskd
 - modify the launchctl script so that the path to the executable goes to 
 /Library/WebObjects/JavaApplications
 - start the launchctl scripts
        - sudo launchctl start com.apple.webobjects.JavaMonitor
        - sudo launchctl start com.apple.webobjects.wotaskd

 The other advantages is that you can switch back to the Apple versions just 
 by changing the launchctl scripts.

 I'm running the Wonder versions of 4 servers (all CentOS Linux boxes) and 
 it's super stable.

 Hi Simon,

 Thank you very much! Seems to be quite a detailed manual. I shall do it on a 
 test server and see how it goes. Will let you know the findings soon.

Re: Deployment setup on a OS X box

[Simon]

 Are you deliberately compiling the adaptor from scratch?  If nothing else I 
 guess that means you don't have to determine what architecture you're on.  
 I'm just thinking you could compile it once for each, store those somewhere 
 and download them with that script, then you could avoid installing gcc.

yeah, i know what you mean. at first i was just downloading the binary
versions from mdimension but i thought building it each time will
avoid any issues (or maybe even highlight issues) each time you boot a
new instance, because each time you boot an amazon linux box you get
the very latest version.

i envisaged a situation where a minor upgrade to apache for example
might rock the boat if we were using binaries, whereas building
natively stands more chance of navigating around such issues.

i don't have a lot of experience in this area - maybe someone with
more knowledge of the woadaptor could recommend which is the best
approach ?

ultimately my vision for ec2 automation is that we have some
uber-script that runs first to determine what sub-scripts you need to
run based on the ami you are booting. we're going to publish some more
scripts (hopefully this week) that are examples of how to auto-deploy
your apps right the way from hudson to your freshly created ec2
instances...

Re: Textarea with character countdown

[Simon]

no component, but here is how we do it:

label for = messageMessage/label
  wo:text value = $comments id = message onKeyUp =
return count(this,255,'myCounter') /
  p class = descYou have
span id = myCounterwo:str value =
~255-comments.length //span
characters left./p


function count(a,b,c){
var dif = b-a.value.length;
while (dif  0) {
a.value=a.value.replace(/.$/,'')
dif = b-a.value.length;
}
document.getElementById(c).firstChild.data=dif;
}

 Hello,

 I have a use case for a textarea with a Twitter-style character countdown 
 from some specifiable limit.  Specifically:

 1.  Text area with a character limit count somewhere nearby.
 2.  Count decreases by one for each character typed.
 3.  Count decreases by the total length of anything pasted in.
 4.  Excess content is not prevented, but the count goes negative.

 Basically, I'm describing exactly (New)Twitter's widget.  (I want to use it 
 for SMS message content.)

 So, here's me as an optimist: does anyone have or know of a WOComponent that 
 does exactly this that I can just drop right in?  :-)  Failing that, I'm not 
 up to speed on Twitter's API or, in particular, exactly what parts of their 
 UI are re-usable—does anyone know if this widget is freely usable in any 
 form?  Failing that, can anyone recommend a good Javascript implementation of 
 something like this, preferably _not_ using JQuery (as I want to just drop it 
 into pages already using Ajax.framework)?

 Failing all of those, I'll write one myself.

Re: Deployment setup on a OS X box

[Simon]

my 2 cents...

i got sick of trying to remember where all the bits and pieces go, so
now on linux we use this structure:

/opt/WOApplications
/opt/WOWebServerResources
/opt/WODeployment

our apps go in WOApplications
our web server resources go in - yes you guessed it - WOWebServerResources
and javamonitor  wotaskd go in WODeployment

deployment for idiots. like me.

oh, and we've published a script that builds a linux box inline with
this from scratch:

http://webobjects.s3.amazonaws.com/wo-install.sh

it's only tested on amazon linux, but i guess it might work on simliar
flavours (centos/redhat). the script is part of a wider effort to
fully automate deployment on ec2...

 I'm setting up a Mac Mini Server, and it's the first time since 2008 that 
 I'm setting up a OS X box just for deployment. I installed WO with 
 woinstaller.jar, but I did forget that it won't install it in /, saying that 
 /System already exists. So I installed it in /Developer, and had to create a 
 symlink for /Library/WebObjects to /Developer/Library/WebObjects.

 Now, since it's a deployment box, I don't actually need WO on it, I only 
 need the Apache adaptor, wotaskd and JavaMonitor with embedded frameworks. 
 So I'm thinking of creating a installer (.pkg) that would :

 - create /Library/WebObjects and /Library/WebServer/Documents if they don't 
 already exists

 And /Library/WebObjects/Configuration
 - install wotaskd.woa from Wonder, in /Library/WebObjects/JavaApplications
 - instal JavaMonitor.woa from Wonder, in /Library/WebObjects/JavaApplications

 I'd simplify this and put these both in the same directory.


 - install the two launchctl scripts
 - install and load the Apache HTTP adaptor from Wonder

 Where will this go?  You will also need the apache.conf file.


 Any opinions on this?

Re: REST routes in JavaMonitor

[Simon]

i've just started using these for auto-configuring production servers.
it's cracking stuff - thanks!

is there any javadoc, or a list somewhere of all the functions
available ? if not, where do they live in the code (i.e what class
handles them ?). stupid question, i know, but i'm new to rest and i
can't find them anywhere!

i'm still having to mangle the SiteConfig.xml with sed to set things
like the adaptor URL, javamonitor password etc. are their functions
for this kind of stuff ?

thanks, simon

 Good morning!

 Yesterday, I committed REST routes inside JavaMonitor, this is the stuff that 
 was demonstrated at WOWODC 2010. With those routes + the direct actions Anjo 
 added last year, you can control almost everything remotely (make sure 
 JavaMonitor is not open to the world!). The code was added to the trunk of 
 Wonder (the Wonder53 build) so if you want to play with it, make sure you get 
 it from this build.

 Below is a couple of call examples. Please note that if JavaMonitor requires 
 a password, you need to append ?passwd=X at the end of the URLs.

 

 Fetching the details of all applications :

 curl -X GET 
 http://127.0.0.1:56789/cgi-bin/WebObjects/JavaMonitor.woa/ra/mApplications.json

 Adding a new application :

 curl -X POST -d {id: 'AjaxExample',type: 'MApplication', name: 
 'AjaxExample',unixOutputPath: '/opt/Local/Library/WebObjects/Logs', unixPath: 
 '/opt/Local/Library/WebObjects/Applications/AjaxExample.woa/AjaxExample'} 
 http://127.0.0.1:56789/cgi-bin/WebObjects/JavaMonitor.woa/ra/mApplications.json

 Adding a new instance :

 curl -X GET 
 http://127.0.0.1:56789/cgi-bin/WebObjects/JavaMonitor.woa/ra/mApplications/AjaxExample/addInstancehost=localhost

 Delete an application :

 curl -X DELETE 
 http://127.0.0.1:56789/cgi-bin/WebObjects/JavaMonitor.woa/ra/mApplications/AjaxExample.json

 Delete an instance :

 curl -X GET
