While doing a fresh install of 11i vision on Oracle Enterprise Linux 5, RapidInstall gave the following error:
Rapid Install Wizard will now launch the Java Interface.....
Exception in thread "main" java.lang.UnsatisfiedLinkError: /11istage/startCD/Disk1/rapidwiz/jre/Linux/1.4.2/lib/x86_64/libawt.so: libXp.so.6: cannot open shared object file: No such file or directory

This error comes because libXp.so.6 library is not present in /usr/lib. The rpm which contains this file is libXp-1.0.0-8.x86_64.rpm. It is present in the Oracle Enterprise Linux 5 DVD in /server directory. So copy this rpm from the DVD or CD and install it:
原因：出现找不到jre这样类似的错，是因为缺少支持打印的图形化动态链接库libXp.so.6，缺少系统安装包
libXp-1.0.0-8.x86_64.rpm
解决方法：
rpm -ivh libXp-1.0.0-8.x86_64.rpm
yum install libXp.so.6
