Hello! After I installed the JAVA JRE as followed from Installation Notes of FC4. But following messages displayed for JRE which displayed only the 1.4.2 is best but I am tested ok in sun.com which displayed 1.5-06. Did I missed some setting ? Or any affect on using java programs ? Thank you. Wong Kwok Hon = quote started = [root@ringofc3 ~]# alternatives --config java There are 2 programs which provide 'java'.
