  2. Uncompress and extract the downloaded file. The download includes a Readme.txt and two .jar files with the same names as the existing policy files.
  3. Locate the two existing policy files inside the folder <java-jre-home>/lib/security/.
     • local_policy.jar
     • US_export_policy.jar
  4. Replace the existing policy files with the unlimited strength policy files you extracted.
