I am not able to run any applet with Java 8 Update 91.
I everytime get following message:
Your security settings have blocked an application signed with an
expired or not yet valid certificate from running.
This message appears despite inclusion the website into Exception Site List.
Can somebody give me any advice? Thanks in advance.

A general exception occurred while trying to access CAS. Please notify your system administrator.
I am new to this topic, so I started from basic.
I followed step by step process from the following site
https://wiki.jasig.org/display/CASUM/Demo
when I finished step-8, everything was fine and I got similar kind of logs as mentioned in step-8, when I hit this url
http://sathishkumar:8080/servlets-examples/servlet/HelloWorldExample
I am getting "CAS is Unavailable
A general exception occurred while trying to access CAS. Please notify your system administrator" error.
I created certificate with sathishkumar as Common Name(CN) because it my computer name.
I am running it in windows
The question is, How to solve "The certificate is not valid and cannot be used to verify the identity of this website" error?.
Here are the details:
I have a signed applet that has been working fine, until I updated Java to 8u25 (1.8.0_25-b18). Now, the application shows an alert message "Do you want to continue? The connection to this website is untrusted". There is a note in this message too, "The certificate is not valid and cannot be used to verify the identity of this website".
The applet is loaded without problems. But when the user tries to use a specific function of that application, the warning message is displayed.
I've checked the java console when this happens, and this warning message is displayed right after these lines:
security: Obtain certificate collection in SSL Root CA certificate store
security: Invalid certificate from HTTPS server
network: Cache entry not found [url: https://sub.domain.net:9876, version: null]
The application is downloaded from a different domain, say "https://app.domain.net/.....", so no jars are downloaded from "https://sub.domain.net:9876", but the applet connects to "https://sub.domain.net:9876" to send/receive data.
The applet is signed correctly, and so far, it meets all the security requirements according to Java. This issue seems to happen when the application tries to connect internally with an HTTPS url like https://sub.domain.net:9876. That sites' SSL certificate is valid, issued by GoDaddy and has not expired.
Again, this started to happen after updating my JRE to 8u25. I've tested adding the offending URL to Java security exception list, with no success.
Here are a few screenshot of this problem:
This is the warning message displayed:

Edit 10/21/2014:
I noticed this: When I click the link "More Information" displayed in the "Security Warning" dialog, the reason displayed says:
The application is being downloaded from a site other than the one
specified by the security certificate.
Downloading from "sub.domain.net"
Expecting "*.DOMAIN.NET"
This message says the application is BEING DOWNLOADED FROM "sub.domain.com", and that is false. The application (applet) is already downloaded, and it is only using that domain in an internal HTTPS request, to get/send business data, not to download additional Jars, JNLPs, etc.
I found how to solve this issue, and thanks to Steffen Ullrich for a valid proposal.
This is related to the certificate's Common Name (CN) value. In my case, that value was *.DOMAIN.NET, and to change it to *.domain.net, all we had to do was a procedure called "Domain Transfer". This means, to change the CN to *.REKEY.DOMAIN.NET, and then to change it again to *.domain.net. We could not change it to *.domain.net directly because the certificate provider says *.DOMAIN.NET and *.domain.net are the same.
Now, this issue happened only with Java 7.71 and Java 8.25. Previous version of Java 7 and 8 don't have this issue (SSL certificate restrictions for CN in a different casing).
Anyway, this solved the issue, and now we receive a gentle information message about the domain:
If you trust the certificate and the website you are accessing, hit Continue to get past this message.
However, unless you ABSOLUTELY trust that website, this is a red-flag warning that you may not be accessing the page you think you are, and there may be a serious security risk. That's why it warns you. A "wildcard certificate", if that is indeed possible, would be a Bad Idea unless it restricts itself to a very specific and limited set of domains.
I doubt this is case-sensitive.
I have tried to install Java EE 7 with updatetool to be able to run Java EE Tutorial examples.
But the installation of updatetool fails. I have tried to start updatetool installation from the command line on my elementary os, then I saw the error when installing updatetool.

Error text example 1:
Input/output error: Connection failed for URL http://pkg.oracle.com/javaeesdk/7/native/release/manifest/0/updatetool#2.3.5%2C0-56.2852%3A20111207T211721Z: 503: Service Temporarily Unavailable
Could not download application packages. This could be because:
- a proxy server is needed to access the internet. Please ensure that
the system proxy server settings are correct, or set the 'http_proxy'
environment variable to the full URL of the proxy server.
- the package server or network connection is slow.
If you are getting time out errors you can try setting the
PKG_CLIENT_CONNECT_TIMEOUT and PKG_CLIENT_READ_TIMEOUT
environment variables and try again. For example to increase
the timeouts to 300 seconds set them to 300
- the package server is down or otherwise inaccessible or it is
generating invalid data. Please contact the provider of the package
server.

I don't use any proxy server. Help please!
I had the same - it's because their site is so unbelievably slow.
The output you showed tells you what to do, increase the timeout.
But sometimes it just needs to be run again, which worked in my case.
You can download the tutorial from Oracle Java EE 7 SDK download page.
Just download the latest Java EE 7 SDK, and unzip. The tutorial is inside the glassfish4/docs folder.
I have managed to install updatetool finally, after 3 days.
My advice for everyone who has the same problem:
Try installation several times in the morning, afternoon, evening and at night. And maybe once you will have successful attempt :)
The problem was not on my side.
My client has run in to some trouble with their java application (I have not played in Java land in a long time). The application uses Kerberos for authentication and works great up to Java 1.6.30. But as soon as they upgrade to Java 1.7.11 they begin getting the following error:
javax.secrutiy.auth.login.LoginException: Unable to obtain the Principal Name for authentication.
The JVM is running on Windows 7 in a windows domains so we are authenticating against AD.
Was there a breaking change made between releases? Is there a code change they need to do to get this fixed? Or did somebody on the Java team goof up?
TIA
Hi you could be running into this potential problem.

Java 6 doesn't respect the registry value while java 7 does.
I have a Java applet which is using the Apache commons.net API for FTP. I initially ran the applet without signing it, and it threw a
SocketException : Software caused connection abort
I looked this up online and found that my firewall was blocking my applet. So, to confirm this, I disabled my firewall and ran the applet. It worked fine.
Then, I followed the instructions given in another site to self-sign the applet using nnetbeans:
Project Properties -> Enable Web start -> Self-sign using generated key
Still, the same error persists. I can't find anything that explains this particular error.
