Activating Flash, ActiveX, Java Applets

Could someone explain to me "specifically" what do "you" do
to remove the IE6 message "Press spacebar to activate or use
control" message from a coldFusion "Cfform" or "CFgrid"? I've been
successfull at removing the message from a Flash movie in my
Javascript. But how do you do that with a whole Coldfusion form.
With the stand-alone Flash movie in my Javascript we write
the "string" that produces the Flash object to a varible, then call
a external Javascript file to "document.write" the object out
again, but how would you do that with a Flash Coldfusion form or a
CFGrid? The Flash Coldfusion form's code is generated dynamically?
Could someone explain specifically what I need to do to
correct this problem?

This has been 'fixed' in cfmx 7.02. There is a
hot fix for cfmx 7.01.
The 7.01 hot fix points to an article on the Adobe site that
describes the issue. The same article points to a Microsoft article
which has other various scripting workarounds that can be
used.

NAC Agent/ActiveX/Java applet

Hi,
For L3 OOB deployment , does any one know how the NAC agent/ActiveX/Java applet refresh the IP address for the client??
i know that In the Login Page configuration, two options need to be checked to use the ActiveX/Applet webclient to
refresh the client’s IP address:
- Use web client to detect client MAC address and Operating System
- Use web client to release and renew IP address when necessary (OOB) .
But what i need to know how the agent/ActiveX/Java applet refresh the IP address for the client???
are these programs ( agent/ActiveX/Java applet ) triggers the client machine to do that???
regards
MAM

MAM,
You're right. The applets do indeed trigger a dhcp refresh on the machines. This is to avoid bouncing the port which can be problematic when you have IP phones.

Flash in java applet

is there any way to use .swf in java applet?I mean a banner with flash at the top of applet.

is there any way to use .swf in java applet?I mean a
banner with flash at the top of applet.I am not sure if there is a way of doing it... but as far as I know it can't be done.
However, SWF and applet can both be used as embedded objects.

32-bit flash and java plugins freeze firefox and gnome on 64-bit linux

I have installed FC13 64-bit and am running 32-bit firefox 3.6.8 so that I can run flash plugin.
When I start 32-bit firefox 3.6.8 and go to site with flash or java applet, firefox locks up my gnome desktop necessitating a reboot of my computer.
Firefox 3.6.8 32-bit
Flash 10.1r82
Java jdk 1.6.0_15 32-bit
I have used a similar configuration on 32-bit FC13 with 32-bit Firefox 3.6.8 and everything works fine. No lockups.

Hi!
I finally solved this problem. The 32-bit libflashplugin required a 32-bit libcurl library that is not installed by default on 64-bit linux systems (at least not on Fedora). Once I installed 32-bit libcurl libs, flash and java plugins starting magically working.
In my opinion, 64-bit Fedora has done a poor job with 32-bit compatibility viz a viz 32-bit libs. I will submit an improvement ticket to Fedora folks about installing more 32-bit libs on 64-bit distros.

Running a java applet from flash

Hi,
How do you run a java applet from within a Flash movie?
Is it necessary for the user to download a java interpreter, or is there an interpreter somehow built into their browser that can run applets?

I was wondering , I don't know too much about Flash
I remember seeing some classes in amongst the Flash
files when it installed , but couldn't tell you whart they
do (at the moment , but you've got me interested)
maybe you should rethink your strategy for building your page (and your movie) maybe build the movie around
your applet , or preload it then replace a an area of your movie area with your applet (the way you handle rollovers).
the advantage is you can make calls to applet methods
from Flash as it supports Javascript.
jus remember to set the scriptable <PARAM> to true
Users shouldn't have to download the plug-in or JRE
you should specify it in the OBJECT or EMBED tag so
if they don't have it , the browser will tell them.
of course this is going to change as Microsoft are stopping support for JAVA , users will then have to download the plug-in from Sun in order to view or use JAVA on the internet.

Running an ActiveX component wrapped as a Java Applet. How to do it?

I have a legacy ActiveX/ocx plugin that the client wants to be run as a Java Applet. They think that will make things J2EE compliant.
How would you wrap that? are there libraries to help?
Thanks in advance

thanks for trying to help since I wasn't able to find the appropriate category given the new change (discussions.apple.com/thread/6421739)

Java Applet in Flash CS4 (ActionScript 3.0)

Hi Guys,
I wonder if anyone can help me as I am a little confused.
Is it possible to insert a Java Applet into Flash CS4 (ActionScript 3.0)
Any advice is much appreciated
Thanks

I wouldn't swear to it, but I don't think you can "import" and run an applet internally in flash, but you can call it as an external file from flash and display/run it in an html container for example.
Just as flash (swf) is run through FlashPlayer as the runtime environment, Applets use the Java Console as its runtime environment.

Perhaps one can do it using AIR but not Flash IDE (CS4) or ActionScript.

Access Flash Player position from Java Applet

Hallo Everybody,
as a part of my diploma thesis, I have on a HTML Page two
objects, one is a Flash Movie, streamed from a Flash Server, the
other is a Java Applet. In the Java Applet I have a button "Get
time of Movie". When the user clicks on this button, the Applet
shoud ask the Flash Player about it's actual position (min, sec)
and the Applet should get this information back. I think, with the
ExternalInterface Class might it be possible, but I have no idea
how. Could anybody help me?
Thanks

Advanced: Java Applet in Flash

We're trying to embed a photo gallery uploader which allows
users to browser their folders and files from within the flash
site. I know that a java applet may be the best solution and am
looking into how to access similar functionality using flash
remoting.
Can I do this natively with flash and avoid using java
altogether? Do we need JRUN? Can we use our Com Server for this?
Can someone give me more information on how to accomplish this?
Appreciate it.

Flash has a FileReference class that allows you to do uploads
and downloads via a flash front end. I am only aware of doing this
with .NET as the back end server technology. I also think that the
FileReference class may be specifically for working with .NET but I
am not sure.

JAVA Applets from Adobe Flash/MS Silverlight?

SAP has recently announced that it will no longer support
invocation of JAVA applets directly from its "WebDynproABAP" or
"WebDynproJava" applications. (Until recently, SAP supported an
"iframe" UI element that could be used to run JAVA applets from
within WebDynpro applications - soon this will be only doable in
frames within SAP's portal via "client-side eventing".)
However, SAP will be supporting invocation of Adobe Flash and
MS Silverlight from within its WebDynpro Applications.
So here's my question.
From an SAP WebDynpro application, I want to pass parameters
to the JAVA applet "JMol" and have it run in a separate frame.
Since I will no longer be able to call this applet directly from
the SAP WebDynpro application, I'm wondering if I could pass
parameters to Adobe Flash or MS Silverlight and have Flash or
Silverlight invoke the applet for me with the correct parameters.
(I would still only want two frames - the one that the SAP app is
running in and the one that the JAVA applet winds up running in.)
Relevant links for this question are:

and its follow-up here:

this question, and for any answer(s) anyone can provide.

This link:

says that javascript can be called from Flash
So is it as simple as invoking the Java applet from the
javascript ?

How to use UI Element "AbstractApplet" to embedd java applet in WDA

Hello,
I want to embedd a java applet in a WebDynpro ABAP application and I've found the following statement on SAP online help:
The Active Control Framework (ACF) enables the development of applets or ActiveX-based controls that can be embedded in Web Dynpro ABAP.
Link:[AbstractApplet|http://help.sap.com/saphelp_nwpi71/helpdata/en/47/b915bc878a2d67e10000000a42189c/frameset.htm]
Is there any further help, how to use this (abstract) UI Element to integrate a given java applet?
Kind Regards,

Hi,
As per the link you gave,
In the View layout, You can use the UI elements like - AcfExecute and AcfUpDownload. For upload and download the things.
Try to use these UI elements and get the reference of the Abrstact APplet class and use the methods inside it.

How relevant is Java Applet technology in 2006 for wide web deployment?

How relevant is Java Applet technology in 2006 for wide web deployment?
I'm developing a website which requires deployment Internationally to as many users as possible. Many people advise to stay away from Java applets, others say only use Java 1.1 (AWT limitation), some say use Flash, others say stay away from applets and plugins altogether.
Of course it depends on the content. I have interactive 3D content currently powered by Java 1.1 applet BUT I have been using Swing to introduce custom GUI functionality but which I know may limit compatibility. I'm torn by this whole debate and what impact it will have on the relevancy of my website.
How many users out there have browsers that will cope with my content?
Then there's the issue of all the various different browsers nowadays. I'm testing for IE and Netscape on Windows platform, but what about other browsers and OSes on other platforms? I notice that some websites have a page with tables to show users what browser is and is not compatible with their web content. How far must a web developer go to test all these things exhaustively?
Then there's the issue of a 16MB download for the latest Java plugin if a user's system is not up to date. Can all modern browsers handle Java even with the latest Java download?
Or should I just tell the user to get a compatible browser? Another 10-20MB download, depending.
Or how about Flash? That reportedly has a vast International deployment base, but do I need to pay for a Flash editor / IDE / compiler? So far I've been using freeware (HTML, Java, NetBeans, PHP, MySQL, PNG images) to achieve excellent results within my ludicrously limited budget. The Flash Player is only a 930KB download, and that is quite user friendly even if I must tell a user to get the latest version � only 2 minutes download on a 56K modem or about 15 seconds on DSL followed by a 2 second really easy install.
Look here to see where Java ranks against Flash and others :
http://www.macromedia.com/software/player_census/flashplayer/
I know Java. I use it for apps and now applets. I get it to communicate with my server's PHP and MySQL. It works well on my machine, but will my applets work for millions of users world wide with few technical problems? Looking through Java forums I see developers struggling with Java Applets in Safari on OSX but not on Windows. Then another has problems with Applets in IE on Windows but not on Netscape. Then one browser struggles with key events . . . it's like a mine field out there and I'm struggling for clear direction.
Microsoft's support for Java has been poor. If I depend on Java Applets now and for the next year, then will they still be supported 3 or 5 years from now? Or will I have to write off this investment in Java development effort and then switch to something else? Or switch to something else now?
Does Sun Microsystems somewhere reveal how ubiquitous their JVM deployment is?
Perhaps I'm totally misinformed, but Java Applets seem to be dying out. I'd really love to hear from other active web developers out there doing stuff for wide deployment to mass markets.

Since my zwebsite is already using Java 1.1 for 3D visualization I've decided to standardize on Java 1.1 to gain maximum browser compatibility. To add another technology like Flash at this point may just complicate matters, especially for me.
I'm now converting my Swing GUI to AWT. It wastes a lot of time, but the effort should be worth it in terms of the deployment success rate - in theory at least :-)
Just imagine if Java 1 had Swing . . . dream on!
In the deployment stats noted in my first post on this thread they state that Java has 86% world wide desktop deployment. Problem is that I bet that figure only relates to Java1. I wonder what pathetic percentage is true for Java2?
Regarding the use of Java for content rich dynamic content for world world wide web browser deployment . . . I'm rather disillusioned at this point. It seems for this application Java is stuck indefinitely at Java1 and the cool things they developed after that cannot be used effectively. Please note that I am ONLY referring to wide browser deployment. For stand-alone apps and targeted web deployment (where you can reasonably expect your user to upgrade his/her system for a good reason) Java is still very cool.
As for Java WebStart: I can see the uses for it, but it just does not fit into the browser application where the general public enter your web pages and see cool content inside the essential context of your webpage. This last point is vital for any serious web site. If the object of the site is to deploy a useful app to the user (like a forex trading front-end with GUI) then use Java WebStart by all means.
After this website, I'll invest in Flash. I'm sure Flash is not without its share of issues, but it has 97% deployment of nearly the latest versions and user download/upgrade is under 1MB. On top of that it does not seem to suffer from corporate relationship woes like those between Sun and Microsoft.
After all, Flash is labelled as a 'player' and not a Virtual Machine. Mass users out there want to play rather than know about complex and bulky IT stuff.

Problem Launching Java Applet with Plug-in: Version 1.4.2_01

Hello out there:
I recently installed j2re-1.4.2_01 on my home computer but have been unable to access Web sites emmploying JAva applets. The following is an email exchange with Jeff Hall of Lowell Observatory, manager of an educational site hosted by Lowell, trying to resolve my problem. The messages are better understood if read in reverse order.
I'm hoping that someone will recognize the source of my problem and can recommmend a solution. I would appreciate any help offered.
Thanks,
Mike Coucke
Hi Jeff:
Well, I guess the problem lies with me somewhere. Here's my answer/status to your questions/suggestions:
1) I'm using MS Windows Me version 4.90.3000
2) I do have the directory C:\Windows\.jpi_cache\jar\, but the only thing in it is an empty folder labeled "1.0". The file LP.jar does not exist anywhere on my hard drive.
3) I tried several game sites that utilized Java applets and got the same results: the Java cup in the upper left corner followed a few seconds later by the red "X". So, evidently the problem is somewhere on my end.
I'm going to post our email exchanges in a Java Users Forum managed by Sun to see if anyone out there can solve my problem. However, if you have any more suggestions, I'll be glad to try them.
Thanks for the help.

Mike,
Rats! What version of Windows are you using? It's a little strange to
see the user directory set to C:\Windows; if you're using XP, I'd expect
it to be something like C:\Documents and Settings\Mike Coucke. In any
event, the output that is of concern is these two lines:
java.lang.ClassNotFoundException: LPRemote.class
Caused by: java.net.UnknownHostException: proxy
It looks like your browser is not finding our server's IP when it comes
time to download the necessary Java code.
LPRemote.class is the fundamental code that runs LOPARC, and your
browser should be downloading it automatically when you click connect.
LPRemote.class is stored along with a bunch of other classes in a file
called "LP.jar" that you download from our server. So, if you go to C:
in Windows Explorer and do a file search for LP.jar, you should find it.
On my machine, it's stored in a directory called ".jpi_cache\jar\" in my
user home directory. Let me know if you have this file, or the
jpi-cache directory.
One other thing you might try is going to a different site that you know
uses Java applets -- I think some of the online game rooms at Yahoo use
Java. See if other sites that use Java load correctly. Then we'll know
if it's our server specifically, or a more general problem on your end.

Hello Jeff:
I still have the Java "blues". I followed your instructions, but am still unable to launch a LOPARC session. After an initial failure, I uninstalled all three Java versions I had (1.4.0, 1.4.1, 1.4.2), then reinstalled 1.4.2_01 from the Sun website.
Now, when I try to launch LOPARC, I initially get a blank window with the Java cup in the upper left corner. After about 20 seconds, the cup changes to a red "X". During those 20 seconds, the following appear in the IE message bar at the bottom of the window: "Applet LPRemote notinited" (their spelling) which changes to "Loading Java Applet Failed..." when the red "X" appears.
Following is a copy of the log from my Java Console during all of this:

Once again, I hope that you can help. My experience has been that I usually have some obscure option set incorrectly and that causes me great grief.
Thanks fo your help,

Hi Mike,
Try it now. I think this problem has arisen because Sun just
released a new version of the Plug-in (1.4.2), and when we released the
public beta of LOPARC, only one relevant version (1.4.0) was available
and the LOPARC code was written to look for that by default. I have
just recoded the relevant routines so they should now cause your browser
to simply pick up the latest 1.4 version of the Plug-in you have
installed, whatever it is. I "broke" Java on my machine to replicate
your problem, and the code I inserted today did fix it. Hopefully it
will have the same effect for you. I am running IE 6 and plugin
1.4.2_01 (as accessed via Tools->Sun Java Console).
One broader problem: some (non-LOPARC-specific) users on the Sun
forums have reported the "JRE collision" you are seeing when multiple
versions of the Plug-in are installed on the same machine. So if the
fix I made to our code doesn't work, one option would be to uninstall
all Java components from your computer and do a fresh install of the
latest runtime environment.
Let me know how/if this works. Thanks for the feedback and for your
patience.
Best regards,
Jeff Hall

Hello Jeff:
So far, I have been unable to launch a LOPARC session. I repeatedly
get the following error message:
"Exception: java.lang.ClassNotFoundException: LPRemote.class"
My browser is MS Internet Explorer version 6.0.2800.1106 Initially I was
using Java Plug-In version 1.4.1 and received the error message. I went
to the Sun website and downloaded/installed Java Plug-In version 1.4.2
and still get the message.
Before I try to launch LOPARC, I can select Tools->Sun Java Console from
IE's pull down menu to check my Java Plug-In version. When I try to
launch LOPARC, I get the following message:
"Applet(s) in this HTML page requires a version of Java different from
the one the browser is currently using. In order to run the applet(s)
in this HTML page, a new browser session is required, press 'Yes' to
start a new browser session." If I select 'No', I get the following
message: "Java Plug-in detected JRE collission"
If I select 'Yes', a new browser window opens and then I get the first
message above.
Can you help?

Dear Michael Coucke:
Thank you for registering with Lowell Observatory's online education
site. We hope you enjoy using it and visit regularly as we continue to
expand its features and capabilities. This is a one-time welcoming
email.
For your records, your user ID is xxxxx, and your password is #########.
You'll need to supply these each time you log in.
This site gives you access to research-grade equipment including a 16"
telescope, CCD detector, and image processing software. Our online
archive of data is now available 24/7. The telescope will be opening to
our onsite users in May, and on select nights to the Internet at large
in June.
We have designed this site so you don't need a huge monitor or a
supercomputer to use it. All pages are viewable on screens running at
800x600 resolution or higher. To use LOPARC, you'll need a Java-enabled
browser with the Java 1.4 plug-in installed. If you don't have the
plug-in, you'll be prompted to download it the first time you attempt to
connect. This is an admittedly large (9 MB) but one-time-only download.
This site works correctly under Internet Explorer version 5 or higher.
If you use Netscape, you must be running version 6 or higher, and
display or applet behavior anomalies may occur.
If at any time you can't connect to our server, simply try again later.
We do experience several power outages each year, particularly during
Flagstaff's summer thunderstorm season. Our server is fully protected
and backed up, and can be quickly brought back on line, but any active
user sessions will be lost. Thanks for your patience during these
inevitable downtimes.
Your questions, comments, suggestions, and bug reports about this site
are always welcome. On behalf of the LOPARC development team, thanks
for signing up!

Hi Mike,
I see this in your logs:
Java(TM) Plug-in: Version 1.4.2_01
Using JRE version 1.4.2_01 Java HotSpot(TM) Client VM
User home directory = C:\WINDOWS
Proxy Configuration: Manual Configuration
Proxy: http=proxy,https=proxy,ftp=proxy,gopher=proxy
Proxy Overrides:
I just helped my Dad set up his computer with a new
cable modem, and had the situation where we couldn't
access any secure Web sites. The cable folks had us
disable the proxy. It looks like the error message is
saying it can't find your proxy server, and the logs
you posted say that you've decided to configure your
proxy manually, rather than using the settings from
IE (which is how mine is set up in the plugin
control panel.)
Could that be the problem?

Forms Client Java Applet waiting several minutes

Hello,
We use Forms 10.1.2.0 and html/javascript/plsql applications.
All forms applications are working but
we have the problem that from time to time the client java applet must wait minutes until there is an answer from the forms-servlet (especially when there is high activity in the system).
More than one user is working in the form with high activity - the applet sends a request
over the network - after 4 minutes the result is shown and you can go on working
without problems.
So a lot of users think the application has crashed and terminate before.
The applet shows no error messages.
There is no sign that there is a lost connection between applet and servlet.
It is not reproducible. That means you can work 2 hours and everything is ok
or you work 5 minutes and you have to wait.
network problems?
firewall problems?
do requests of the forms servlet to the database have minor priority on the application server
than html/plsql requests?
any ideas?

when the problem occurs (user has to wait 3-4 minutes) we found in the log
3 heartbeats from the forms client within 2 seconds ?
after 3-4 minutes the forms client is ok (user can go on working)
and the pings are every 2 minutes (like it is expected).
The application.log file may contain duplicate posts requests with
identical pragma header numbers, indicating that the client
is resending
requests due to network packet losses. Under normal circumstances,
only the last Post request, terminating a Forms session,
should contain
a duplicate pragma header number.
...a network problem ?
anyone else who had the same problem ?
