Hi

The flex app has an auto update that after the image has loaded, a  
10 sec timer runs and reloads the image. I load the image into a new  
bitmap and then swap the images.
Currently it stopped working. it seems to only show the last image,  
like a caching issue. If I call on the php app the image updates  
with every reload.  I don't see what might be causing this.


Any suggestions.

I was just looking at Tour de FLEX, and there were Effects like

Re: [flexcoders] MaxWait time in the server.xml file in Tomcat 6.0

[Kevin F. Benz]

Simon, you need to address the performance aspects and determine why the
servlet is taking so long. You should be seeing servlet performance well
below a second (unless you are navigating millions of rows) as I expect the
database access is killing you (although I have no real data at this point
on which to make that assumption). Remember, there are client-side timeouts
as well so you could increase the server timeout and have the client go
away.

At this point, you need to take your queries and find out how long they are
taking in the database tools to see where to start looking. If the query
performance is acceptable given the database size, then you need to look at
recursion issues in your servlet.  If the database performance is not
acceptable, then you need to look for race conditions, filters and indexing,
table scans, etc etc.

Re: [flexcoders] Performance Question

[Kevin F. Benz]

Well, you have to avoid over the wire activity as it will cause a traffic
pattern called a ³galloping herd². Basically servlet latency causing
latency, causing And so forth. Your keyboard buffer will end up getting
ahead of the over the wire call and end up with enough spooled key events to
make it seem like your app has died.

The startup load is ³OK² but you have to deal with the impact of having the
client-side data getting stale compared to the server. Perhaps limit the
download to some number of characters allowing for the round-trip to occur
after the user has typed in enough characters.

Remember, although the numbers you present seem low, you have to plan for a
much larger sample, one where the numbers of users substantially escalate or
you wish to repurpose the algorithm in a more data-centric operation.

Re: [flexcoders] SWF Encryption using the Local Encrypted Store

We also found that the encrypted local store wasn¹t effective for

container as we needed to be able to allow a user to backup and recover it
as data in the ELS directory isn¹t necessarily available to the Vista user

Re: [flexcoders] AIR auto-updates

[Kevin F. Benz]

I have found a couple of things but the numbers are pretty low. I¹m a big
Air fan.

Every once in a while, we would get a user that got an incorrect language
version. For example, a US computer ended up with a Portugese version of the
Air runtime. The numbers were small but in 45,000 users, it probably
happened 5 times. It had also happened prior to 1.5 with a Japanese version
being installed. Localized Air runtimes isn¹t something you can determine as
the installed takes care of it.

Likewise, and infrequently, an Air upgrade ended up displaying Black Boxes
or return an Error Code: 0 in the upgrade UI. Again low in population but
you need to be ready for this one as the only way to completely clean Air
out was to uninstall AIR, blow off the ELS/TLS directory (encrypted local
store), and reinstall. I could never reliably repro this.

My biggest critisizm about the Air installer/updater is the lack of
effective installation logging. Although you can configure Air to do some
rudimentary logging, you have to put a configuration file in a directory
that a Vista user doesn¹t have access to (see below). It should be an
installer option rather than what feels like a hack. Corporate IT
environments aren¹t crazy about the distribution of a RIA anyway (unless it
has a business purpose) and asking IT to troubleshoot an Air install
typically made for less than happy people.

Tight access privileges really weren¹t much of an issue other than testing
and user access of the filesystem. The Vista user, for example, can¹t even
get interactive access to their own ³Application Storage Directory² Air
alias. We made a mistake by using that directory (who knew) to download
into. Air could put files there, but we had a bunch of users that we
downloaded music to who couldn¹t end up finding it. We ended up moving our
storage outside of the Air aliases. Likewise the encrypted local store. We
bailed on using it (only an administrator can see it) and built our own
encrypted file structure.

Re: [flexcoders] itunes clipboard format not understood in AIR

The clipboard in AIR is text only. It¹s not going to work for a binary file.
I have asked Adobe about binary clipboard support and I don¹t expect it

iTunes will move files around to balance it¹s directory tree (unless you

Re: [flexcoders] itunes clipboard format not understood in AIR

[Kevin F. Benz]

4 sure. We had some luck with a javascript window where we would drag the
file but the problem was the only real way to know where the file was going
to be (if the plan was to keep a reference to it) was to camp on the library
xml files and those get rewritten when iTunes closes or music is imported
(or cover-art is downloaded, etc,etc). Remember, you can ask iTunes to
organize your library into a common tree and that killed our attempts to try
to persist our own reference in Air. The Flex XML parser isn¹t completely
happy with the iTunes library XML format so we ended up breaking the XML up
and creating a track-only document but it was pretty fragile as there were
so many ways to blow up the xml. KFB

Re: [flexcoders] Profanity fliter

[Kevin F. Benz]

On the Flex side I have implemented objects that catch a change event on an
input control but it¹s impossible to stay ahead of users means of subverting
profanity filters in a client implemented solution. These days we do it one
of three ways.. If possible, we implement an editorial review process if the
amount of content is manageable. Second, when we have to do inline
filtering, we keep a dictionary and then pattern match on the server side,
if that proves ineffective (based on how stringent it needs to be) we do the
³Do you find this content objectionable² and pass those to an editorial
process.

Re: [flexcoders] Blazeds - Fault Event has no headers or message body

[Kevin F. Benz]

Sounds like the request isn¹t even hitting the server. That would be my
guess otherwise you would at least see the return header. I have always
found it useful to use restclient 2.2 on google code as you get a cool
little gui to manually set HTTP header values, authenticate as part of the
request. You can also persist requests to disk as well. It¹s a jar so you
will have to call it directly from the command line but I think Dustin did
provide some documentation. If not, let me know and I¹ll give a hand.

You can run a swf in Air but I expect that is the least of your headaches.

Hi, all.

I'd appreciate any suggestions on how to implement the following use case:

(1) a swf running in a browser on the client-side sends simple numeric data
to a server-side script. 
(2) the server-side script calls a second swf located on the same server as
the script, passing it the numeric data. 
(3) this swf uses the data to generate a layout in flash that is rendered to
an image and either (a) returned directly as binary data to the server-side
script or (b) saved locally on the server so that the server-side script can
access it.

It's steps 2 and 3 that have me stumped. How can I call a swf without a
browser, and by extension, without the Flash Player? Is there some way to
call a swf directly as an executable that can return output to the calling
process?

Thanks much!

Here are few things I have found.  They may help, they may not.

 

Ultimately I find that projects under version control have been my issues.
Let me explain. I have found (at least through SDK 3.0 and 3.1) that an
upgrade to the SDK causes the local project file to go through some update
but when a later SCM update occurs, you get an old versions project files
and crasho. The new SDK is expecting a known project file and gets
hair-balled by what came in from source control. I have tried cutting and
pasting another copy, reverting, trying to fix by hand, etc but in the end,
I find that I have had to create a new blank project and copy all the files
(except for the project files) and reconfigure the library path, and the
rest of the goo. You will need the new library properties, and other . (dot)
files as well from the new project. Bring in the old ones and you die. I'll
bet you can close each of your projects and the crashes will stop when the
offending project(s) is closed. 

 

The list of source files to be compiled can be corrupted.  I believe this is
the real issue with reverting project files but don't have a good handle on
why - but you should try disabling incremental compilation.  Add
"-incremental=false" to the compiler settings in the Flex Compiler tab of
the Properties.  This will effectively ignore the .cache files.  Compile
times will be longer - but hopefully that is offset by having a stable
environment. Flex uses cache files to persist previously compiled objects.
And a clean build doesn't necessarily refresh the cache files.  It is benign
to backup and remove those .cache files. They live in a few places so you
will need to find the
.metadata/.plugins/org.eclipse.core.resources/.projects directory and within
that directory, you will find one for every Flex project. For example

Eclipse 3.4.2 (M20090211-1700)
FB 3.0.2.214193
Flex SDK 3.3
JDK 1.6.0_13

My eclipse.ini is:
-showsplash
org.eclipse.platform
-framework
plugins\org.eclipse.osgi_3.4.3.R34x_v20081215-1030.jar
-vm
C:\Program Files (x86)\Java\jdk1.6.0_13\bin\javaw.exe
-vmargs
-Xms1024M
-Xmx1024M
-XX:PermSize=256M
-XX:MaxPermSize=512M
-XX:+UseParallelGC
-Dosgi.requiredJavaVersion=1.5
-Djava.net.preferIPv4Stack=true
-Dcom.sun.management.jmxremote

Our Flex application is a collection of 30 projects (one main one and 29
flex library projects). All have to be open at the same time or else you get
build(dependency) errors.

There's a few projects that are linked to many of the other projects. For
example, we have a project that holds all of the VOs. Making changes to that
project always took a long time to build (several minutes), but now it
crashes with OutOfMemory errors.

I've run jconsole to watch the JVM performance statistics. I don't fully
understand all the numbers, but I can see that my PS Old Gen pool gets 100%
full, and that's when I usually expect a crash to happen soon.

My machine has 8GB of RAM, although I can only allocate 1GB to Eclipse it
seems. If I raise -Xmx higher than 1024M, Eclipse won't even start.

Anyone have any suggestions?

Thanks,
~Geoff

Trying not to be the heretic in the group, Mac, Linux and PC have an
installed ftp client that can be easily used if you take a few moments to
understand the commands underneath all of these clients. Get a command line
and type in ftp. I use it extensively for scripted backups and automated
deployment scripts and the commands cross all platforms.  If you need drag
and drop, it's not for you, if you want to do something simple..

RE: [flexcoders] Flex with IBM Websphere / DB2

[Kevin F. Benz]

Whoa. 

 

You probably have few options as the Enterprise Application on Websphere,
what services it exposes and how they are presented ultimately will
determine what you can do. For example, the application could expose beans
as endpoint services (emulating SOAP methods), could expose JMS (MQ
Services) or EJB's as traditional RMI services. Either way, you need to
start there to determine what your options are.

Subject: [flexcoders] Flex with IBM Websphere / DB2

 






I've been working with Flex using .NET HTTP/SOAP web services and MS SQL
Server for a while. Recently I started a new project using IBM Websphere
Application Server (6.1) and DB2. The environment is setup with a simple
Apache/Linux web server (no Websphere or other app server components), then
a Webspere App Server 6.1 behind a firewall, and finally a DB2 server (also
behind the firewall). The only server that is accessible externally is the
Apache/Linux web server.

My Flex app requires data from the DB2 database, and I'm used to getting it
via HTTP/SOAP web service calls. However, with nothing but a bare
Apache/Linux web server that is accessible externally, I'm trying to figure
out how to best create a simple server-side HTTP listener that will take
data requests, communicate with the WAS/DB2 servers, then send the data back
to the Flex client.

What choices/options are there for this scenario? I do have the capability
of installing some server-side components to the Apache/Linux web server.

RE: [flexcoders] Preventing duplicate database entries in ColdFusion and flex

Select the count of those that have those credentials and if the number is
greater than zero, return an error, otherwise do your insert.

how can i prevent duplicate database entries in coldfusion and flex. for
example for registration forms, i would like that if someone registers the
same combination of username and password that already exist in the db, the
entry is rejected and the user is alerted. thanks
