im new at linux and i need some help i have no idea, i installed an older version of java but the game im trying to play needs a newer java. need help what kind of command do i have to put in to install java 7?
I can see there is a no good java version that was bundled with my centos 6.x and I cannot get rid of it rpm way
$ rpm -qa jre\*
/* java alternatives shows the older version and not the newer version.
I want to play this java simulation: http://www.compadre.org/OSP/items/detail.cfm?ID=9640 in java 3d mode on a linux (ubuntu) system. But it doesn't work.
If I switch to java 3d-mode it complains that java 3d is not installed. sudo aptitude install libjava3d-java didn't help.
Then I did a right click in this java app and selected Diagnostics-> About Java 3D.
