I've changesd my IE 5.0 security settings to be able to run my intranet applet as a trusted applet.
Now I am trying to employ new JDK 1.3 Plugin to do applet
caching.
Java Plugin ignores browser settings and I am getting
security exception in my applet.
How can I avoid it and make Java Plugin "obey" browser
security settings?

Here is what I've changed:
IE 5.0 - Tools - Internet Options - Security - Trusted Sites - "Sites" button - added DNS name (IP address) of
the server where my applet resides.
Also from Security tab - "Custom Settings" button - Microsoft VM Java permission changed to Custom;
button "Java Custom Settings" became visible;
Enabled all options for the "unsigned Content".
Now when I ran my applet I have "Trusted Sites" mark on the lower right corner of the Browser screen. It allows
the third party classes (included in my applet)to access print facilities and write logs.

Actually I can add (and already added) http site for my applet to the list of the trusted sites. It works fine
with Microsoft VM, I am not having any problems.
My applet contains some classes from the third party vendor that are performing functions forbidden for the applets. That is the reason I had to make it a trusted applet. Thus I avoided all security exceptions from the
browser.
The problem started when I tried to use JDK 1.3 Java Plugin
VM instead of the browser VM. Java Plugin does not read and
does not obey my security settings and throws Security Exceptions when instantiating the third party vendor classes I mentioned about.

What does third party applet will do. Are there digitally signed or not.

If there are digitally signed then no probs. Else have to digitial sign or signed there jar atleast. If the applet seems to have some probs or restrictation on the System.
That is when JVM find it does something bad to the sytem it raises SecurityException
