jdk点击安装没反应，jdk安装状态不动

1、根据您的业务需求，需要安装Java环境（jdk_1.6.22版本）。下载地址：https://www.oracle.com/java/technologies/javase-java-archive-javase6-downloads.html。需要注册帐户。否则将无法下载。

2、安装步骤unzip jdk-6u22-linux-x64.bincd jdk1.6.0_22 ln -s /opt/lib/jdk jdk1.6.0_22[root@local-idc-l2f-oss-cst_call ~]# /opt/lib /jdk/bin/java - 初始化VM java/lang/NoClassDefFoundError: java/lang/Object 时发生版本错误
