Dear All: I intalled JDK1.1.1 on Redhat 5.1 on an 586 PC. And I set the path and JAVA_HOME. When I run java, a "Segment Fault" error appears, and there is any results when I run javac. Even though I tried a few different sites to download JDK, the error still remain. Does anybody tell me the reseans and how to solve the problem? I guess it is because the Redhat 5.1 doesn't support JDK1.1.1. I really appreciate any help from you. -Fenghua
