When I activated the application url, I got the following popup message and I couldn't accept/deny this message.
Warning - Security The application's digital signature cannot be verified. Do you want to run the application? Name: ... Publisher: ... From: ... [ ] Always trust content from this publisher. [Run] [Cancel]
Although, there is a checkbox in the message and 2 buttons, I couldn't do anything else than shutting down my browser through the Windows Task Manager.
There are 2 solutions for this problem:
(1) Using this sequence of jar-files for webutilArchive
webutilArchive=jacob.jar, frmwebutil.jarMore info on Oracle Support:
