Reflection ZFE version 2.1.1 released April 2017. These release notes list the features and known issues in this release and information on how to obtain the product. Reflection ZFE provides terminal emulation for 3270, 5250, VT, and UTS host types, while requiring only an HTML 5-capable browser.
Support for scrollback buffer on VT hosts is now available. This option is configured in the Set VT scrollback buffer options of the Display Settings panel.
Reflection ZFE 2.1.1 has updated to Java 8 u131. This update contains patches for multiple security vulnerabilities. For more information, see Oracle Critical Patch Update Advisory.
To complete a successful installation, make sure that you have taken care of these common connection issues:
|
✓ |
Is MSS configured for HTTPS? Connect to the system where the Administrative Server is installed and log in to the Administrative Server. In the Administrative WebStation, open the Security Setup section and note the protocol selection. |
|
✓ |
Verify that both MSS and Reflection ZFE are using trusted certificates. If you are not using trusted certificates, have you configured Reflection ZFE to run using HTTP? |
|
✓ |
Are your connection properties configured properly? In the unlikely event that you have to verify connection information, the container.properties file for both the management component and the Reflection ZFE session server contains the connection properties needed to make the Reflection ZFE to MSS connection as well as the browser to Reflection ZFE connection. |

Other connection issues See Technical Note 2838, Troubleshooting Reflection ZFE Connections for more information on other rare connection issues. |
Technical Support is always available to help you with any issues you may encounter in Reflection ZFE.
NOTE:Reflection ZFE terminal emulation uses WebSocket technology for communication between a web browser and the Reflection ZFE session server. WebSocket is a feature of the HTML5 specification, and is supported by current releases of all widely available web browser software. If your organization has modified router or network configurations to disable WebSocket communications on your network, you cannot use Reflection ZFE terminal sessions. For more information, see WebSocket.
Recommended browsers
It is highly recommended that Reflection ZFE users use Google Chrome or Mozilla Firefox. While Reflection ZFE supports Microsoft Internet Explorer (IE) 10+, there are known performance issues with IE's JavaScript engine that may negatively affect the end user experience with Reflection ZFE.
If you are using an older version of Internet Explorer, you may see these issues:
There are remedies to both these issues, however the easiest solution is to use a different browser.
Key mapping
Certain keys on a numeric keypad and some browser-specific keys cannot be mapped. For example, in Chrome, Ctrl+n and Ctrl+w cannot be mapped.
Some anti-virus software blocks WebSockets
Reflection ZFE requires a WebSocket connection between the web browser and the server. Antivirus software might prevent WebSocket connections, especially when ports 80 or 8080 are used. If you think your antivirus software may be preventing WebSockets, first try a different port. For troubleshooting, see http://websocketstest.com
Field outline in a 3270 session
The 3270 attributes for field outlines are not fully supported. Reflection ZFE currently supports underline and overline; however, left vertical line, right vertical line, and combinations of the four line types are not yet supported.
SSL 3.0 is disabled by default
For security reasons, enabling SSL 3.0 is not recommended. However, for hosts that absolutely require SSL 3.0, follow these steps to enable the protocol:
Stop the applications or services that will be using SSL 3.0.
Open <install-dir>/jre/lib/security/java.security in a text editor.
Remove or comment out the line jdk.tls.disabledAlgorithms=SSLv3.
