怎么确认AIX下jdk的版本呢，我用java -version显示的是1.4.2
但是我在websphere下systemout日志文件中看到的是1.6 webshere版本为7.0
************ Start Display Current Environment ************
WebSphere Platform 7.0.0.13 [ND 7.0.0.13 cf131039.07] running with process name hnzzyx1srv2Node01Cellhnzzyx1srv2Node01server1 and process id 680504
Host Operating System is AIX, version 5.3
Java version = 1.6.0, Java Compiler = j9jit24, Java VM name = IBM J9 VM
was.install.root = /websphere/AppServer
user.install.root = /websphere/AppServer/profiles/AppSrv02
Java Home = /websphere/AppServer/java/jre
那这个机器下的JDK版本到底是哪一个版本呢
