Java application usage description
The JRE relies on periodic checks with an Oracle Server to determine if the JRE is still considered up-to-date with all the available security fixes (above the security baseline). In the past, if the JRE was unable to contact the Oracle Server, the JRE continued to behave as though it is the most recent version with regard to security for an indefinite period.
To avoid this problem, a secondary mechanism that does not rely on external communication has been added to the JDK 7u10 release. From the 7u10 release onwards, all JREs contain a hard-coded expiration date. The expiration date is calculated to end after the scheduled release of the next Critical Patch Update.
JREs that are unable to contact Oracle Servers for an extended period of time now offer additional protection after a reasonable period and do not continue to behave as if they were up-to-date with regard to security fixes.
More information can be found here: Java Expiration Date.
Java plugin can also be blocked by Web Browser if the manufacturer decides that given Java plugin version presents a possible security threat.
In both situations all security warnings are generated by the Java plugin or the Web Browser itself. Unfortunately, we cannot influence that and force HyperDoc to start properly in that case.
| Warning | ||

It is important to understand, that possible security threat only exists when using Java Applets that come from unknown source. It is perfectly safe to use HyperDoc software that will not impose any security threat to client computer, independently from Java version used. All Tessel Java applets have a valid digital signature that ensures their origin. It is important to check if the applet is signed by "Tessel Systems AB". |
| Info |
|---|
Tessel regularly checks and assures that HyperDoc Online application works correctly with latest Java release. Latest Java can be used with standard security settings. |
Possible ways of overcoming problems with using outdated Java version
| Tip |
|---|
Please remember that tips described below may lower your computer/network security. The best way to keep it most safe is to have latest Java version installed. |
- Changing Java Security level in Java Control Panel to the lowest position
- Adding your HyperDoc Online site to Exception Site List (from Java Control Panel - Security tab) - more details can be found on Oracle website.
- On Internet Explorer turn off Protected Mode for Internet zone (this mode blocks Java if it's not the latest version).
- Or in Trusted zone add your HyperDoc Online url to trusted sites list (this zone by default have lower security than other zones).
- Use Deployment Rule Sets (only for standalone HyperDoc Online installations).
Those are administrative action than can be done by System administrators to whitelist the RIA and javascript domains.
