Access control exception

**winicz** · June 4th, 2019, 02:25 PM

Hi Everyone,

I have a server and I need to remote control through Java based application.
In the Java console I see this info:

Java Plug-in 11.181.2.13 x86
Using JRE version 1.8.0_181-b13 Java HotSpot(TM) Client VM
User home directory = C:\Users\ETVKX

Unfortunately due to errors this is impossible:

1. At first there is Java Application blocked error (ApplicationBlocked.jpg)
- adding the presented URL to the Java exception list solves (probably) the problem as I see new errors as described in next point.

2. Next I receive two different errors:
a) AccessControlException for FilePermission (accessdenied.png)
b) AccessControlException for PropertyPermission (mcs.debug.error)

I added the three below lines in the java.policy file to avoid the errors:
permission java.net.SocketPermission "10.123.166.20:2000:, "connect";
permission java.util.PropertyPermission "mcs.debug", "read";
permission java.io.FilePermission "C:\Users\ETVKX\IBM\10.123.166.20", "read";

But I still receive the same two errors presented in point 2.

- What is "mcs.debug" ? Is this Java related?
- Is the syntax correct that I am using inside java policy file?
- What additional policies I can use to avoid the errors?

Any help would be useful for me as I am struggling for more than month now. Thx.

Regards,
Robert

I haven't worked with Security settings for a while. It would take me a while to setup a test, but I don't have a remote site.

I remember having to add lines to an Exception List:

Java icon in Control Panel
Web Settings tab
Exception Site List
add a line like the following to the list:
file:///D:/JavaDevelopment/Testing/WriteFile/

A sample .policy file entry:

grant codeBase "http://127.0.0.1:8080/WriteFile/" {
  permission java.io.FilePermission "<<ALL FILES>>", "write";
};
 
grant codeBase "file:/D:/JavaDevelopment/Testing/WriteFile/-" {
  permission java.io.FilePermission "C:\\Temp\\writetest.txtXXXX", "read, write";
  permission java.io.FilePermission "D:\\Testing\\writetest.txt", "read, write";
};
