Reflection for the Web 2014 (All Editions)


When attempting to copy then paste text in a terminal session, the ability to paste may intermittently be disabled and unavailable. This can occur after upgrading to Java 7 Update 55 (1.7.0_55) and above.


This behavior is due to a specific defect in this version of Java. For more information: http://bugs.java.com/bugdatabase/view_bug.do?bug_id=8043393. This defect is scheduled to be resolved when Java 9 is released, in September, 2016.


Reflection for the Web versions 12.0 HF10 (12.0.521) and newer, 12.1, and 12.2 have a means of avoiding this paste problem, achieved by adding a special applet parameter to session configuration, as follows:

  1. Log into the Reflection for the Web Administrative WebStation and open “Session Manager”.
  2. Click the session name you want to add the parameter to.
  3. Click the blue “Applet Parameters” button.
  4. Notice the “Custom Parameters” section at the bottom of the page.
  5. Add a new custom parameter “alwaysEnableEditPaste” (without quotes). Note: the parameter is case sensitive. Be sure to capitalize the E for Enable and Edit and P for Paste.

  2. Click the “Add” button to add the parameter.
  3. Check to see that the parameter now displays in the “Current parameter”.window.

  1. Click on the “Continue” button on the bottom left.
  2. Click the “Save Settings” button to save the change.

Sessions that are running will need to be closed and reopened for the change to take effect.

Applying the Workaround to all Sessions

In environments where this issue occurs in several session configurations, you can apply the workaround without needing to edit each session. This can be done using a launcher template “customloginpage.jsp” as described in KB 7022339, and adding the needed applet parameter in the “rweb:applet” tag:

<rweb:param name="alwaysEnableEditPaste" value="true"/>

Adding the applet parameter to the launcher template causes the parameter to be applied to any session launched from the server.
