As the Update 21 for Java 7 introduces some changes to the Java browser plug-in behavior that enable you to make more informed decisions before running the Java applet in the browser, please see the following link for additional information:

Please be aware that Update 21 for Java 7 also checks the proper notation of the used links regarding upper and lower cases. Therefore the notation of the link you use in the browser to access your arcplan application has to exactly match the notation of the links contained in your html startpage. For example if "http://myserver.mydomain.com/..." is used in the browser to access the application, the links to the CGI and the client component used in the source of the html startpage must not be "http://Myserver.mydomain.com/...". Java will then detect different origins and show a warning message.
