A customer got this Java security warning on one of our ancient java components on a web site we develop:

Java has discovered application components that could indicate a security concerns.

The java applet is a tiny applet that does very little (it is simply a dropdown with the ability to write freetext). Is it a simple way to avoid this security warning?

The applet is something we have developed a long time ago, which has been running in our web solutions for years.

  • Have you seen the jQuery UI combobox? It may achieve your intent without Java. http://jqueryui.com/autocomplete/#combobox – antik Mar 06 '13 at 17:42

Sun/Oracle changed something in Java SE 6 Update 19 and up in relation to mixing signed and unsigned code. The linked article has tips on solving this.

  • It is our experience that the "change setting in Control Panel" does not work 100%. – Thorbjørn Ravn Andersen Feb 07 '11 at 10:59
  • @Thorbjørn Ravn Andersen - Not that it is an approach I would try(1), but have you reported the failure of the Control Panel based solution to Oracle? 1) Only for the fact that changing the CP seems a solution targeted at large companies where the Sys Admin can change the installation/options of every Java set-up in the shop. – Andrew Thompson Feb 07 '11 at 11:53
  • @Andrew, we didn't have time to make a thorough investigation when this happened, and hence could not do a proper bug report. We just found that this happened again (for a Java WebStart application) even with all switches set properly. A proper fix is scheduled for our next release. – Thorbjørn Ravn Andersen Feb 07 '11 at 12:01
