My question is : is there an elegant way to give an answer to the following questions : - determine the JRE version used in the Internet Browser - give the end-user or the applications the possibility to switch to a version different from the default version - can this been done without restarting the browser - how should we do it: java-applet, active-X, javascript, ... This problem comes from the fact that we thought java should have less dependencies on the installed run-time components and we stupidly assumed by installing the latest run-time the older applications using java in the browser could run without any problems. The option to permit to user himself to install other software (e.g. yet another JRE version) is unacceptable and impossible at my company.
