Configure Java applet security policies

Replace Java policy files​

The C:/RPA/registry folder contains the java.policy file which provides additional permissions for jvm-agent. This agent is needed for properly connection between RPA Grid and Java applications or applets.

Copy and replace the existing java.policy file to Java run-time environment on your machine.

It is important to copy it to system run-time JRE which is used to run applets: JRE_HOME/lib/security.

If you have installed a JDK bundle, copy java.policy to JDK bundle: JDK_HOME/jre/lib/security.

note

Most likely, JRE/JDK home is located in the C:/Program Files/Java or C:/Program Files (x86)/Java folders. Check and update both x86 and x64 versions (if installed).

Fix Java security restrictions for applets​

When you are running Java applets in Internet Explorer, you can get an Application Blocked by Java Security popup.

Application blocked by Java security

It happens because Java blocks applications with self-signed certificates by default. To get around this, you need to add the target site into Exception Site List.

  1. First of all, open Java Control Panel by pressing (Win + R) and entering javaws -viewer. Java control panel should be opened.

  4. Click the Edit Site List button.

To use your custom applets, add them to Exception Site List too.
