1.System.getProperty的问题？

public class test {

public static void main(String[] args) {
System.out.println(System.getProperty( "test.initscript"));
System.out.println(System.getProperty( "java.version"));
}
}
the result is:
null
1.3.1_10

如何自己设置一个系统非默认的property,如test.initscript="123456",
使上面的程序输出结果为：
123456
1.3.1_10

谢谢！

谢谢您的rapid response！在命令行上通过。

我用的是Eclipse,
RUN->run->arguments
然后在program arguments里，写上了：
test.initscript=123456

but,the result still is:
null
1.3.1_10
请问，在program arguments里，应如何填写。

另外，有无可能不通过命令行的方式，而采用调用property文件的方式，来采集这个参数？

Posted by: erongd Posted on: 2004-04-13 16:14 In Eclipse you have to put the property in "VM Arguments". -Dtest.initscript=123456. In order to load it from property file, you have to create a <name>.properties file then load it through ResourceBoundle class.
