We are facing this issue on our clients machine.
Our project uses a third party java applet to open the files in respective softwares.
On windows7 we don have any issue but we have issue on windows8 OS
our project is working fine in IE10 and FF browsers. of windows8
this error is thrown only in chrome.
but when we execute same third party demo site which uses this same java applet to open the files in respective softwares, that is working fine in all browsers without making any changes in settings.
I have read many replies from different ppl that we need to changes the client java secutiry settings.
But how can we ask all our clients to make this setting so this is not a proper solution for our problem.
Please see the image below
![Error message][1] is
"Your security system have blocked an application with expired or not yet valid certificate from running"
please help me solve this ..
Go to Control Panel -> Java -> Security -> Edit Site List
Solution published in my website:
http://www.myerrorsandmysolutions.com/application-blocked-by-security-settings/
Go to Control Panel
Java
in the Security tab click the “Edit Site List…” button
click Add button
insert the URL of the website that you want access in (URL should begin with http:// or https://)
click Add button
click OK button
click OK button
Note: you could find an icon Java (32-bit) rather than Java.
If you won’t find in Control Panel a Java icon or the “Edit Site List…” button is missing and you are sure that Java is installed, open a text editor and create a file with name exception.sites containing the URL of the website that you want access in (URL should begin with http:// or https://) and save it in the following path:
C:\Users\username\AppData\LocalLow\Sun\Java\Deployment\security
where
username
is the name of the user.
go to Control Panel -> Java -> Security , choose minimum security level , Medium(Least secure setting), then click ok , save and try again...

Site Exception List is a new security feature since sun Java 7. It can be configured on Windows through the control panel. How do I configure it on a Linux distribution?
Just run this:
echo 'https://asafesite.com
https://another.url
https://and.anotherone.com' > ~/.java/deployment/security/exception.sites
You can check Adding a site to the Exception Site List and follow the steps provided there to configure Exception List on Linux.
Linux/Solaris - Run the jcontrol command.
Choose the Security tab.
Click the "Manage Site List" button near the bottom.
A new window will open.
Click the Add button.
Click OK. The window will close. You may see an additional prompt if
you use an unencrypted protocol such as http or file. Choosing
encrypted protocols defends against potential man-in-the-middle
attacks.
Back on the control panel, click OK to close it.

gmail use some functionality by which they reload all tabs for the login. that means if we open login form of gmail in different different tabs. then login in single tab gmail automatically reload all the pages and redirect to mail page . how it is possible ?
is there any particular frame work to implement this?
You have multiple possibilities, like:
- Websockets
- Push notifications
- Long polling
I won't recommend you any tools for that, as this may change over time, you will find plenty of resources on Google.
If you are using Chrome browser, then I would suggest you to add an extension like "Reload All Tabs". Once you added this extension you can easily reload all the open tabs by clicking the icon of the extension.
I have a self signed application, when i load it in browser it give this warning (Do you want to run this application) each time. I don't want this pop up to appear. I have tried all the settings in java configure setting.

Java has further enhanced security to make the user system less
vulnerable to external exploits. Starting with Java 7 Update 51, Java
does not allow users to run applications that are not signed
(unsigned), self-signed (not signed by trusted authority) or that are
missing permission attributes.
WORKAROUND
It is highly recommended not to run these types of applications. However if you still want to run these apps, run only if you understand the risks and implications.
As a workaround, you can use the Exception Site list feature to run the applications blocked by security settings. Adding the URL of the blocked application to the Exception Site list allows it to run with some warnings.
Steps to Add URLs to the Exception Site list
Go to the Java Control Panel (On Windows Click Start and then Configure Java)
Click on the Security tab
Click on the Edit Site List button
Click Add in the Exception Site List window
Add url to Exception Site list
Click in the empty field under the Location field to enter the URL
I'm trying to use the desktop class in client/server application.
I want the default browser to open on the client side when the client clicks on a button. What happens is that the browser opens on the server. How can I fix it?
Thanks
If you call any Desktop method on the server, then of course the reaction will occur on the server.
If you want a window to pop up on the client, then call the method on the client.
What kind of client are you using?
If you're using a rich Java client, then that change should be relatively easy.

In the lab I work in, we use Mozilla 1.7 for Sun Java™ Desktop System and Firefox 2.0.0.4. My goal is to modify an existing Java application (run via executable jar) to communicate with our web-based login system.
I am open to the idea of using both Java Applets and JavaScript to accomplish this task, but I have not found a way to integrate these two technologies in any browser but Netscape Navigator and Internet explorer.
Is there a way to do this using either of the two aforementioned browsers?
A more concrete example:
1. Launch application
2. Click a "login" button
3. Be prompted for a password
4. In the background, have the application connect to the web-based login server, enter the username (known by the app) and the password, navigate to the time clock section and "click" the Punch In button
5. Pull the timestamp of the login (typically displayed on the browser) and display it in the app
Look at HTTPURLConnection and perform POST of the same values login form contains to the same URL.
