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CLASSPATHC:\Program Files\Java\jdk1.6.0_03\lib;E:\workbench\lib\javax.servlet.jar;JAVA_HOMEC:\Program Files\Java\jdk1.6.0_03Path%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Microsoft SQL Server\90\Tools\binn\;%JAVA_HOME%\bin;

测试：

helloworld.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. * *************************************************************************/public class helloworld {    public static void main(String[] args) {        System.out.println("Hello, World");    }}
