如何安装J2RE

mingjun_du

我在LINUX环境下安装ROSE HA,在字符环境下可以正常使用,但进不了图形环境,按照手册上的说法是没有安装J2RE,但我安装J2RE后,还是不行,手册上是这样说的
2.5    Install Java 1.2 (For GUI Administration Tool)
        In order to run Rose HA Administration tool you need to install one of the following software.
      1.JRE 1.2 or later
      2.JDK (Java Developers Kit) 1.2 or later


If you want to use GUI administration tool:
   Use command:
   Rose# cd /opt/roseha/binRose
   Rose# ./gui.sh
我按以上方法就是运行不了图形界面,我想应该是没有设置环境变量,应该如何设置环境变量让Rose# ./gui.sh启动是自动启动起JAVA运行环境呢,谢谢
