Impact on Client Delivery:
Pulse Connect Secure provides the adaptive client delivery mechanism in which the fallback option to Active-X based client delivery is Java based. The Java based delivery relies on the Java plug-in being enabled on the browser and when disabled the end-users will not be able to install or upgrade client components on non-IE (Internet Explorer) browsers.
The screenshot below is a sample error that end users may see error when trying to login from a Safari browser on MAC OS X 10.8 machine where the Java Plug-in is disabled or when Java is not installed.
Some other common error messages from browsers when Java is not installed or disabled.
"An add-on for this website failed to run"
Impact on client initialization and launching:
When end users login using a browser either the Active-X (AX) control or a Java Applet is used to automatically initialize and launch the client components. When both AX controls and Java plug-in are disabled or not available then a user signing-in from a web browser will not be able to launch client components.
Impact on Java based applications:
Applications that are inherently Java based (like JSAM, Java Applets accessed via the Rewrite Web Access and Premier Java RDP applet) cannot be used when the Java Plug-in is disabled.
