一、Linux

# change posix version for compatability for .bin to unpack
root@bt:/home# export _POSIX2_VERSION=199209
root@bt:/home# ./j2sdk-1_4_2_07-linux-i586.bin
# and then change back
root@bt:/home# export _POSIX2_VERSION=200112
#1.2、配置环境
root@bt:/home# vim /etc/profile
JAVA_HOME=/home/j2sdk1.4.2_07
PATH=$PATH:./home/j2sdk1.4.2_07/bin
CLASSPATH=:/home/j2sdk1.4.2_07/jre/lib/rt.jar
export JAVA_HOME PATH CLASSPATH
#配置完,logout 重新登陆后，如果配置成功，执行javac返回正确选项。
#linux下编译含有package的.java，不能正常运行 .class程序，需要包含#package进行编译
二、Windows
2.1、环境变量配置：
选择Administrator的用户变量（注：系统变量配置也行）
JAVA_HOME: D:\Program Files\Java\jdk1.6.0_21
CLASSPATH: .;%JAVA_HOME%\lib\tools.jar;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\bin;
PATH: %JAVA_HOME%\bin;
配置完和linux 一样注销后，命令行执行JAVAC 成功，环境变量配置成功
2.2、在执行 Eclipse 在Run As Java Application报如下错误：
第一种：环境变量配置错误
[Main Instruction]
Java(TM) 2 Platform Standard Edition binary 已停止工作
[Content]
Windows 可以联机检查该问题的解决方案。
[V] 查看问题详细信息 [联机检查解决方案并关闭该程序] [关闭程序] [调试程序]
第二种： Java和Android程序混合编译
A fatal error has been detected by the Java Runtime Environment:
#
# Internal Error (classFileParser.cpp:3494), pid=4176, tid=7496
# Error: ShouldNotReachHere()
#
# JRE version: 6.0_31-b05
# Java VM: Java HotSpot(TM) Client VM (20.6-b01 mixed mode windows-x86 )
# An error report file with more information is saved as:

#
这个错误的意思，Eclipse 在Run As Java Application 举棋不定，
因为这个项目里面有两种java程序 ：一种是 android application；另一种是java application
所以解决的方法也很简单，把他们移出分开来就行了。
