Class Not Found error in launching Java Applet

I have a web application which launches a Java Applet which references a large number of Jars. When I launch the applet, Java console is launched I can see these jars getting downloaded. In one of the Jars I get exception and Applet load is stopped.
Machine: Windows 7 - 64 Bit
Java Plug-in 10.80.2.15
Using JRE version 1.7.0_80-b15 Java HotSpot(TM) Client VM - Using this JRE as Applet is certified on this JRE version, I even tried with latest JRE.

I have looked in Java Cache and opened downloaded jar and I can see the class is there.
Earlier the exception was on some other class and then I removed all versions of Java and just reinstalled JDK 7 Update 80 32 bit and class which errors out changed.

applet not running even after adding it's URL to exception list

I am trying to run a Java applet. Chrome not support it so I am trying it with IE. I have added the URL to exception list, but it is still showing error that "Your security settings have blocked a local application from running."

javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake in applet

In my web application, I am using a applet which is signed jar and this applet was working fine before jre 1.6 and 1.7. But after security popup and blocking error of applet we had to purchased a java code signing certificate.
I have signed this applet jar successfully and this applet is running without any problem on HTTP protocol. If I open this applet on HTTPS, it start giving exceptions of SSLHandshakeException. I have tried every possible solution to run this but it failed.

In applet, I am using simple applet
import java.applet.*;
import java.awt.*;
public class Apps extends Applet{
public void paint(Graphics g){
g.drawString("Welcome in Java Applet.",40,20);
}
}

In our case we have been getting same exception. But for both java1.6 and 1.7
Our environment was as follows:
jbossAS5.1 with deployed web application and one applet in that web
application
apache web server2.2.1 requiring client certificate(self
signed)
on client side mozilla and explorer with imported client certificate, jre
with imported client certificate
In jre control panel we disabled SSL2 client hello format and also disabled SSL3 and TLS1.2 We left enabled only TLS1.0 and TLS1.1 and everything worked fine since that time.

We are having this same issue.
I believe this is a bug in the way Java implemented TLS 1.2 for SSL.
According to their documentation, https://blogs.oracle.com/java-platform-group/entry/java_8_will_use_tls, they claim that by enabling TLS 1.2, it is backwards compatible with older versions.
However, this is not the case. When TLS 1.2 is disabled, we no longer get the "Remote host closed connection during handshake" error.
TLS 1.2 support can be turned off from the Advanced Settings in the Java Control Panel.
Once this is done, the applets will work.

Java applet won't load in IE after Java 8 upgrade

I have a Java applet that I use to read SD card data from a user's PC. The applet lives on a web site that you log in to. To log-in to the web site you must use a browser certificate. Once you're logged in, you go to the SD card download page, the applet initializes, reads the card data, and sends it to some JavaScript on the page.
The issue that I have now is that the applet does not load since installing Java 8 on my browser. Specifically it does not work in any version of IE (tested 8, 9, 10, and 11). It runs fine in Firefox. I have not tried Chrome.
I haven't found anyone else who has a similar issue. It could be because it is relatively new. Does anyone know why this is happening and have any idea how to fix it?
There is a stacktrace in the Java console in IE8 that looks relevant. Here are some interesting pieces:
javax.net.ssl.SSLHandshakeException: Error signing certificate verify
...
Caused by: java.security.InvalidKeyException: No installed provider supports this key: com.sun.deploy.security.MSCryptoRSAPrivateKey
...
com.sun.deploy.net.FailedDownloadException: Unable to load resource: https://xdc-fqq02.example.com/cardtocloud/cardtocloud.jnlp
Edit: Here's an additional piece of info. The applet works correctly on a different server with with OpenSSL 1.0.1i. The applet does not work with the original server which has OpenSSL 1.0.0m.
Here is the full log. The stacktrace does not appear in the log for Firefox.

Have you tried turning off "TLS 1.2" in your Java Console?
Java8 seems to use TLS 1.2 as default, so in case your server doesn't support it, you might get the same error as you mentioned.
https://blogs.oracle.com/java-platform-group/entry/java_8_will_use_tls

Please add the below command in Java Control panel.
go to java--view--in run time parameter paste this command.
-Djava.net.preferIPv4Stack=true.
It's working for me without any issues.

WebStart dynamic loading jar possible using DownloadService?

I tried to load jar resource dynmically with following code.
DownloadService ds;
try {
ds = (DownloadService)ServiceManager.lookup("javax.jnlp.DownloadService");
// determine if a particular resource is cached
URL url =
new URL("http://localhost:11090/MultiToolkitDemo/download/ubikey-1.0.2.5.jar");
boolean cached = ds.isResourceCached(url, "1.0");
// remove the resource from the cache
if (cached) {
ds.removeResource(url, "1.0");
}
// reload the resource into the cache
DownloadServiceListener dsl = ds.getDefaultProgressWindow();
ds.loadResource(url, "1.0", dsl);
} catch (Exception e) {
e.printStackTrace();
}
But I get the errors as follows.

I think AppInfo is missing. Is there way to insert AppInfo dynamically.
By the way specifying the jar in jnlp like below works fine.
<resources>
<j2se version="1.6+" java-vm-args="-Dfile.encoding=UTF-8" />
<jar href="ubikey-1.0.2.5.jar" />
</resources>

Its possibly a bug in java7. Don't know that for sure.
The issue here is that the application won't launch unless we manually clear the cache every
time before clicking the JNLP link in webpage.
Possible solutions are
Try Java 6 or Java 7 u12.
Look where i found this issue.
