IMPORTANT NOTICE!

With the upgrade of the security system of the Java language implemented by Oracle in January 2014, to run many of the applications below, you must include this site (http://www.uff.br/cdme/) in the exception site list of Java. To do this: follow the instructions on the official page of Java “How can I configure the Exception Site List?” adding the addresses http://www.uff.br/cdme/ and http://www.cdme.im-uff.mat.br (the latter is a mirror of the main site). You have also to decrease the security level from “High” to “Medium”. Even after this setting, Java will still ask you to confirm access to the applications. After you confirm, the application will open finally. For questions, contact us by email: conteudosdigitais@im.uff.br.
