| ||IESO Java policy file ||This revised Java policy file, which replaces the previous existing policy files, contains additional security settings to enable use of the new Verizon CA. The previous java policy files are no longer available as they do not meet IESO MPI java security requirements. The Java policy file must be installed on a userís workstation for successful login and use of the Market Participant Interface (MPI) when using Internet Explorer browser. Without this file, login to the MPI will be unsuccessful. Further instructions for installing the policy file can be accessed here. ||3/26/2010 ||POL |
