启动eclipse是报 no java virtual machine was found after searching the following location
这是一个JDK没有配置好的问题。解决办法如下:
运行CMD。
在里面输入java -version看有没有版本的提示?有的话说明你的JDK是对的,那么就是Eclipse的问题了。没有参考其他方法。
1)如果没有的话:
依次点击:“我的电脑”-(右键)“属性”-“高级”-“环境变量”,弹出Windows的“环境变量”配置卡。
在“系统变量”栏下执行三项操作:
①新建“Java_Home”,值:JDK所在的绝对路径(例如 D:\Program Files\Java\jdk1.5.0_04\)。
②新建“Classpath”(如果已有,则直接编辑),值: .;%Java_Home%\lib (若值中原来有内容,用分号与之隔开)。
③新建“Path”(如果已有,则直接编辑),值: %Java_Home%\bin; (若值中原来有内容,用分号与之隔开)。
或者
CLASSPATH
C:\Program Files\Java\jdk1.6.0_03\lib;E:\workbench\lib\javax.servlet.jar;
JAVA_HOME
C:\Program Files\Java\jdk1.6.0_03
Path
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Microsoft SQL Server\90\Tools\binn\;%JAVA_HOME%\bin;

测试:
[java]
/*************************************************************************
* Compilation: javac HelloWorld.java
* Execution: java HelloWorld
*
* Prints "Hello, World". By tradition, this is everyone's first program.
*
* % java HelloWorld
* Hello, World
*
* These 17 lines of text are comments. They are not part of the program;
* they serve to remind us about its properties. The first two lines tell
* us what to type to compile and test the program. The next line describes
* the purpose of the program. The next few lines give a sample execution
* of the program and the resulting output. We will always include such
* lines in our programs and encourage you to do the same.
