Trying to launch Exor after updating Java to a newer version following Java Plug-in error appears. Clicking Download just takes you to the main Oracle site which is not of much use.
formsweb.cfg on application server makes references to the version of JRE, e.g. 1.6, which then the basejpi goes on to use.
The best option is to change the entry in formsweb.cfg to be a “classless” 1.6, so it does not care if, e.g. the user has 29 or 45. See the example of formsweb.cfg entry below (edited through the EM console and not the file). The 0016 stands for 1.6. And then the 0000-FFFF is the bit which makes it classless.
If latter does not work there is also an option to set the jpi_classid to the neutral one which instructs the browser to use the highest installed version of Java Plug-in.
