java.security.AccessControlException: access denied ("java.security.SecurityPermission" "authProvider.SunMSCAPI")

Question

Till morning everything working fine in my applet. I took Java update and everything stopped. I'm dealing with digital certificate using applet. Here is my stack trace. I followed some oracle article but didn't work.

.java.policy file I'm creating in public void init() method of applet. Its before accessing anything in applet.

grant
{
permission java.security.AllPermission;
permission java.io.FilePermission "<<ALL FILES>>", "read";
permission java.io.FilePermission "<<ALL FILES>>", "write";
permission java.util.PropertyPermission "*", "read, write";
permission java.util.PropertyPermission "user.home", "read";
permission java.util.PropertyPermission "user.dir", "read";
permission java.lang.RuntimePermission "modifyThread";
permission java.lang.RuntimePermission "*";
};

Update: 18th Nov, 2013

Its not working even if using code signing certificate

Answer 1

I cannot comment yet so am putting this as an answer instead.

1. I believe creating the .java.policy file in your applet will be too late - the plugin will have already started up and read the policy files before running any of your code.

2. You could sign your applet and use a jnlp file to assign permissions in the security element

Answer 2

I know it's pretty late to answer here, but adding my solution as I had a tough time with this:

My Issue: While deploying an application (a WAR file) that has dependencies on Bouncy Castle libraries, I faced this issue: `

cannot create instance of
org.bouncycastle.jcajce.provider.digest.GOST3411$Mappings
 java.security.AccessControlException: access denied
("java.security.SecurityPermission"
"putProviderProperty.BC")

`

Here is what I did and it worked for me: Go to: {Installed JDK path}\jre\lib\security\ Open the file java.policy

Add permission: permission java.security.SecurityPermission "putProviderProperty.BC";

Restart the programs to load the changes.

I am yet to understand how exactly this works or if it is safe to just change java.policy file like this (still looking for other ways to achieve such a configuration).

Do take precautions with such a change. More at Oracle's doc
