We are trying to run Engine JAVA application on Linux Red Hat. It runs without any problems on 3 different Linux VM machine that we created. On 2 Physical machines we can run non visual application ??? for example application that create shape file and does not use map bean in it. When we run applications that shows maps on the screen we get error of graphic card on one machine (nVidia graphic card) and core dump on the other one (intel graphic card). Is there any drivers needed for physical machines and where can we find them? Both machines are not connected directly to the internet but we can transfer any files to them.
