Hi , I have java 1.7 installed on CentOS machine. when i tried to run java program i got an error and found that i should run it using java 1.6. Is the best solution to install Java 1.6 and have both java 1.6 and java 1.7 at same time? or is there a better solution. If i should install both java 1.6 and 1.7 , how to do that ? Thank you very much. Best Regards, Asma _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
