1. On each user machine, modify the java.policy file in the <JRE_Install>\lib\security directory and add the lines to grant permissions to run Business Process Server applets.
For example:
grant codeBase "http://<host_name>:<port_number>/sbm/bpmportal/applet/*" {
permission java.security.AllPermission; };
2. Please note that if you change the Business Process Server location, then you must update all users’ java.policy files with the new server location.
