Patch level detected:Univiewer Console 6.1.00
Product Version: Dollar.Universe 6.1.0

Description :Following an installation or upgrade of the UVC Webstart, it is impossible to launch it after executing the uvc.jnlp

Environment

OS: All

Cause

Cause type:
Configuration
Root Cause: The installation / upgrade properties were not properly followed.
The uvc.jnlp has to be edited so that the server / port values reflect the ones of the Tomcat where the UVC Webstart is hosted.

Resolution

In order to fix the issue, edit the file uvc.jnlp on the Tomcat server as stated on the Administration Documentation of Univiewer :

5.4.3 Configuring the JNLP File
Edit the uvc.jnlp file located in the root directory of the application. This file, called from index.html, triggers the download of the Java web start client to the end user’s workstation.
The second line of this file contains:
? Replace with the fully qualified server name of the Web (for example, myserver.domain.com) or "localhost" if the server is local.
? Replace with the port number used by the web or application server, generally 8080 for http/web server For example:

Then relaunch the Webstart Console so that the correct uvc.jnlp file is pushed to the end-user.

Fix Status: Released

Fix Version(s):
Component: Univiewer.Console

Version: Dollar.Universe 6.7.41
