致命错误:无法启动目标虚拟机

Question

我是java和jdbc的新手，试图调试一个示例程序:

Foo.java

class Foo {
public static void main(String[] args){
System.out.println("Chexking dalvik virtual machine on system");
}
}
compiled it with -g flag . javac -g Foo.java
compiled properly . 
Tried to run program using command >java Foo
Got the output .

Then tried to run : jdb Foo

C:UserstestworkspacesampleJava>jdb Foo
Initializing jdb ...
> stop in Foo.main
Deferring breakpoint Foo.main.
It will be set after the class is loaded.
> run main
run  main

据我所知:jdbc无法加载类。是否有任何路径设置，我需要设置jdbc。(我试图遵循这个教程)

我想我错过了一个非常基本的东西。试过谷歌，但同样的想法，但我无法解决问题。

遇到了同样的问题-似乎是由于jdk安装在路径中带有空格的文件夹中，即"Program Files" -将jdk安装到c:jdk中，问题就消失了
