User rejected the cab - signed applet doesnt load

Hi,
I have signed my cab file and IE requests for permissons when I access it. If I deny the permissions, my signed applet doesnt load. Is there any way to make the applet load even if I dont grant the permissions. I expect only the 'out-of-the-sandbox' operations to fail - not the entire applet!
Thanks

I found a solution to this. Details on my blog at:

USER rejected the CAB

Hi everyone,
We have a applet that ask's people to accept the digital certificate. if the user clicks NO the VM shuts down with the message "user rejected the CAB" and the user gets a blank page. this is obviously unnaceptable from a user point of view. is there any way to put some code in to maybe display another page in the event of that happening ? is there some way of doing ANYTHING ??
we are at our wits end!!! please any suggestions!
Thanks

Try the forum microsoft.public.java.vm in Usenet ( http://msdn.microsoft.com/newsgroups/default.aspx?dg=microsoft.public.java.vm&lang=en&cr=US if you do not have a newsgroup reader. )
You maybe will have to fiddle with a litte Javascript in your HTML page (maybe querying if the applet is present in the page. ) If the applet object is not found in the page, or some of its properties are not correct, you could handle it in Javascript, maybe replacing the page with another one.

Security problem when signed applet dynamically load plugins

Hi!
I have one problem : "security problem when signed applet dynamically load plugins"
This is the scenario:
the main program [app.jar]
. contain applet and shared library (interface & implement of common class)
. it is signed and run normally on browser
. it can draw image loaded from other URL [ex] http://bp1.blogger.com/image.jpg
. the image loader is in the shared library
. dynamically load amazon.jar through URLClassLoader and reflection
the plugin [amazon.jar]
. search amazon product [ex] Harry Potter book
. draw image on applet
. use image loader from shared library, BUT CANNOT LOAD IMAGE
The question: "Why it cannot load image, because the image loader is in the shared library which has been signed and working?" I tried to sign the amazon.jar too, but it did not work.
Your reply would be very helpful. Thank you.
Sovann

hello. i have create a signed applet for A.jar. A.jar include two package B and C. the main applet class is within B.
B need some classes in C to run the applet. but i got the error that class in package c are not found.

Signed Applet not loading on Mac OS X if using HTTPS protocol

Hi All,
I need to open a trusted applet on Mac OS 10.2. The applet works fine if using HTTP protocol. But if the protocol used is HTTPS the the applet does not loads and "javax.net.ssl.SSLException - untrusted server cert chain" exception comes on the console.
The error comes for both - Verisign and javakey - signed applet.
On seaching for possible solution on the net, i came across following link: http://www.macosxhints.com/article.php?story=20020525101202503&query=Workaround+for+secure+Java+applet+problems
It says that this is Mac's known bug and gives the workaround as:
1. Access the problematic site with Internet Explorer on Windows. Click on the padlock item and export the certificate to a file.
2. Copy the certificate to your Mac.
3. Use the command
sudo keytool -import -trustcacerts -keystore /Library/Java/Home/lib/security/cacerts -file mycert.cer
to import the certificate file to your keystore (substitute mycert.cer with the name of the file containing the certificate). The keystore is password protected - the default password is "changeit".
4. Restart your browser
But the client cannot be asked to do all this to run the applet.
Is this problem being solved by Mac in their java implementation or is there any other possible solution?
Thanx in advance.
Regards,
Charu

Re: Bug ID# 3268633: cannot load applet class under https connection
Hello Andrew,
Thank you for bringing this problem to our attention. We have received feedback
from engineering on your
reported issue.
Please know that to get Java to recognize the certificate you will need to do
one of two things, depending
on which VM you are using. Since you want it to work with Internet Explorer, we
will assume Java 1.3.1.
In Java 1.3.1 you'll need to add the certificate to
/Library/Java/Home/lib/security/cacerts using
/usr/bin/keytool to import the certificate into the certificate database.
In Java 1.4.1 you should be able to just add the certificate to the keychain
using certtool. For more
details on how to do this, please refer to the information found at
<http://java.sun.com/j2se/1.4.1/docs/tooldocs/solaris/keytool.html>. After
doing so, if you should require
further help from Apple in resolving this issue, we recommend that you request
assistance from Developer
Technical Support. This must be done by filing a Technical Support Incident.

[SOLVED]nm-applet doesnt load

hi i have just installed arch linux and this seems really cool. i like it a lot (i still have a LOT of work to do to make it all the way i want) and im still gonna have to do a LOT of reading before im an expert at pacman and AUR amoung other things.
i just installed nm-applet bcause i want to connect to wireless networks but it fails to run.
in my gnome startup list i have nm-applet --sm-disable
i can connect manually in the terminal by using iwconfig. this wont help me when i am at the university though since we have an 802.1x system (doesnt ever work great with linux by my expirience with different distros. nm-applet version .66 worked pretty well if i remember correctly though).
anyway how can i get nm-applet to work?
i tried to ask for help in the IRC but i got this statement
Please register with services and use the IDENTIFY command (/msg nickserv help) to speak in this channel
ill have to google that in the morning and figure out what needs to be done for that; im just too sleepy for it now
thanks.

ok someone sent me a pm and said i needed to add networkmanger to my deamons list. that seems to have worked for now.
i am interested in trying wicd to see if it works better with the 802.1x network at the university.
this is kinda a weird story:
i installed wicd. there is a menu for it in applications. i clicked on it and it complains about not being root (shouldnt it run the graphical su prompt? actually better yet i shouldnt need to be root to use it). well anyway i tried to remove it and reboot and my keyboard and mouse would no longer work in gdm so i couldnt log in. weird. i started it up again in single user mode and reinstalled wicd and then the system worked fine again. i have no idea how that happened. still interested in giving wicd a chance. i am a noob at arch but that sure didnt work in a way i would expect
EDIT: wicd loads up if i log in as root. btw regular user gets errors pertaining to not being root.
EDIT: oh never mind i needed to add myself to the network group. boy im silly. i guess ill have to do some real world testing next time i go to the university to see which one works better. btw if anyone is searching this check out this wiki post http://wiki.archlinux.org/index.php/Wicd
EDIT: marked this as solved. thanks for the help.

Lotus Notes applet doesnt load after intalling JRE

Hello,
Any ideas how to go about this thing? Without the JRE, the applet is ok, but after installing the JRE, there is a class not found exception. I tried taking off my classpath settings but i still cannot access, but when i uninstalled the JRE, the applet goes ok again.
Thanks for any help extended.
Regards.

When installing the JRE you can specify if you want to use this JRE for your webbrowser as well.
Uncheck this option and you'll do fine.

OS X 10.5.6, Safari 3.2.1 hangs when second applet loaded is signed applet

Dear Forum,
I've been investigating a customer's problem. She is trying to use our
VoIP applet, but it continuously freezes Safari when the Trust dialog shows.
A "Force Quit" is necessary.
I managed to reproduce the problem consistently on
- PowerMac7 OS X 10.5.6 (Build 9G55)
- Architecture: ppc
- Safari 3.2.1 (5525.27.1)
- JVM 1.5.0_16 from Apple
The problem is persistent when:
- the signed applet is loaded as second applet in the browser
- the signed applet is cached by the JVM
Our customer uses:
- Mac Book ProOS X 10.5.6
- Safari 3.2.1
- JVM 1.5.0_16 from Apple
This problem does not occur on:
- Mac OS X 10.4.11 (Mac Powerbook G4)
- Safari 3.2.1 (4525.27.1)
- JVM 1.5.0_16 from Apple
and not on:
- MacBook Air, OS X 10.5.6, 1.6 Ghz Intel core 2 duo
- Safari Version 3.2.1 (5525.27.1)
- JVM 1.5.0_16 from Apple
Steps to reproduce the problem:
Launch Safari.
In (first) page/tab go to
http://www.javatester.org/version.html
(this uses a non signed applet)
Open a second tab. Here go to:
http://ukapi.phonefromhere.com/talk/vtop2.xsql?key=01612884242
This is a signed applet that will ring our office over VoIP.
Click the "Trust" button (signed by PhoneFromHere).
As long as this applet isn't cached by the JVM this will work, so
the first time you will succeed.
Now Quit Safari (not "just" close all Safari windows, but a "real" quit) and repeat the exercise.
The second (and next) time this will fail (only if the signed applet is loaded as second, so the order is important)! This keeps failing until I go (back) to the Java Preference window (via Finder) and explicitly delete the cached files.
The URL will work when loaded first (cached or not).
Some diagnostics, that might help:
I configured the Java Preference window to "enable Logging, Tracing and Show applet livecycle exceptions".
When the applet fails to load (and Safari freezes/hangs), the last few records of the plugin150.log are:
<message>basic: Loading http://ukapi.phonefromhere.com/talk/lib/pfh.jar from cache
<message>basic: Reading cached JAR file from JRE 1.5 release
<message>basic: Certificates for http://ukapi.phonefromhere.com/talk/lib/pfh.jar is read from JAR cache
<message>security: Loading certificates from Deployment session certificate store
<message>security: Loaded certificates from Deployment session certificate store
<message>security: Checking if certificate is in Deployment session certificate store
(and then nothing)
whereas when it succeeds to load, as soon as I click the "Trust" button, it's say:
<message>security: User has granted the priviledges to the code for this session only
The Report is a bit too long to port, I'll include the same text above when sending it.
Model: PowerMac7,2, BootROM 5.1.3f0, 2 processors, PowerPC 970 (2.2), 1.8 GHz, 2 GB
To cut a long story short? Is this a know bug (I couldn't find anything, but you never know)? Does anyone have any ideas how to fix this?
Thanks, Birgit

I have the same issue now after downgrading my Flash plugin. I downgraded from 10 to 9 latest because I like using Camino and for some reason Flash 10 doesn't play nice with Camino. But all of a sudden as I use Camino 2b2 for everyday and Safari 3.2 for banking and such, the browser hangs requiring a forced quit when I close it. I've re-installed the browser twice now with all the previous folders, and preferences erased and caches emptied. I even when to re-installing 10.5.6 and it still crashes, it's odd. Maybe 10.5.7 will address this.
