So I do not know how to change the Java preferences not to complain about this type of variables. but in Preference System/Java/ I only find onglets for General,Upgrade,Java,Security,Īnd Advance and not Web like on PC. I've read on the web that I should change the Java preferences. I am compiling with Eclipse a web application which uses JDK7 on a Mac OS 10.9 MacBookPro.Įverything works fine, but Eclipse validation fails with this strange message: She has a Mac, and unfortunately I am not at all familiar with Mac computers. I sent here a war file of a JSF 2.2 application that I created with Eclipse on my computer, which uses Windows. I'm writing this on behalf of a colleague who is using Eclipse for the first time and is having some problems.
