Issue/Introduction

A OneClick User is unable to launch OneClick Client due to a Java notification error: “Application blocked by Java Security.”

Environment

Release:
Component:

Cause

Upgrade to Java 1.8.xx introduces a change to Java Security where “Medium” setting is no longer available. This may cause Java to block OneClick access due to higher security restrictions.

Resolution

1. If it has not been done already, add the OneClick URL to the "site exceptions" list:

Control Panel > Java > Java Security > Site Exceptions

2. While in the Java Control Panel, go to the Java tab > View. Make a note of the most recent version of Java installed.

3. In a browser, go to OneClick web page > Administration > OneClick Client Configuration. Add the most recent JRE version number into "Supported JRE Version" window.
