Signed applets are giving java.net.SocketPermission exception with JRE 8 was fine in JRE 7 or lower
posted 2 years ago
It was working fine with JDK 1.7 or earlier versions, but once we test with JDK 8 we are getting the following exception
Exception in thread "cth" java.security.AccessControlException: access denied ("java.net.SocketPermission" "IP:PORT" "connect,resolve")
at java.security.AccessControlContext.checkPermission(Unknown Source)
at java.security.AccessController.checkPermission(Unknown Source)

We have an applet, which will open a socket connection to communicate with the server socket application here is the applet code which used to open the socket communication
We are using signed applets, I tested with a java client program from eclipse, this works fine, only with Applet we have issue. may be Applet security need to use full permissions we try with MANIFEST.MF with Permissions: all-permissions and object parameters for applet which doesn't solve the problem.
When we grant in the client machine java.policy to full permissions it was worked fine, but this is not correct way to go ahead forcing to change client machine java.policy.
any help will be appreciated..
