I have installed Web Viewer Build 191 into a new WebSphere v184.108.40.206 cell but the application is not starting and throws errors related to ClassNotFoundException. Can you confirm 191 works for WAS v8.5 ?
I just performed a new install from a maintenance Build of 12.1 Web Viewer and the application will not start. Why?
Web Viewer 12.1 Build 191
If by "installed Web Viewer Build 191 into a new WAS v220.127.116.11 cell" you mean that you downloaded and installed Solution 84 CUMULATIVE BUILD 191 FOR WEB VIEWER 12.1: PTF SO05739 to your new WAS cell, that will be a problem. Build 191, like all maintenance builds, are not to installed. Rather, they should be applied against an existing install, or more accurately, you update an existing install with a maintenance Build.
The prescribed procedure for getting 12.1 Web Viewer at Build 191 to a new WAS cell is to first install the 12.1 Web Viewer base product - download CA Output Management Web Viewer Plus MULTI-PLATFORM 12.1 S1409 from support.ca.com and install it. Then download and apply SO05739 CUMULATIVE BUILD 191 FOR WEB VIEWER 12.1 or the latest maintenance.
