I am giving linux mint a shot and am trying to install the newest JDK 7 and have no idea what directory to install the files in. I am not doing the install manually, I'm using the installer that comes with the JDK w/ Netbeans download. Once I start the installer it asks where I want to install the files and I'm getting conflicting answers on where I should put it (either the /usr/lib , usr/bin , usr/local , opt etc..). Even if I just randomly pick one of these directories, it won't let me, stating "The specified installation folder is read-only." For any linux users out there, where exactly should I put the files? Thanks!
