请尽量用准确的文字描述作为标题

我是初学者；刚装了JCreator2.5pro
jdk为 j2sdk-1_4_2
编了个HelloDate.java 结果运行出错，不得其解，望各位前辈指点，为谢。

代码：
// HelloDate.java
import java.util.*;

public class HelloDate {
public static void main(String[] args) {
System.out.println("Hello, it's:");
System.out.println(new Date());
}
}

运行后的错误提示是：
--------------------Configuration: j2sdk1.4.2 <Default>--------------------
Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object

Process completed.

如能解救，感激不尽！（补充：运行环境已配置好）

Posted by: why Posted on: 2004-09-02 00:45 Which OS are you using? How do you tell 运行环境已配置好? What's the output of java -version ? How did you run the little program? Something like C:\> java HelloDate ? Do you have an older version of Java installed? Have you tried resinstalled J2SDK?

Posted by: mingfanli Posted on: 2004-09-02 02:00 我装的2000系统，环境变量的设置是 CLASSPATH=.;jdk1.4.2\lib\dt.jar;C:\j2sdk1.4.2\bin; JAVA_HOME=j2sdk1.4.2 Path=j2sdk1.4.2\bin 然后在dos下运行 java HelloWord.java 出现一样的提示 Error occurred during initialization of VM java/lang/NoClassDefFoundError: java/lang/Object 请中文跟我教我，我不懂英语。

Posted by: why Posted on: 2004-09-02 02:45 ?????? where are the drive? CLASSPATH=. JAVA_HOME=C:\j2sdk1.4.2 PATH=%JAVA_HOME%\bin;...... if you use Command Prompt, you may run the following to setup the environment on that Command session: SET JAVA_HOME=C:\j2sdk1.4.2 SET CLASSPATH=.;%CLASSPATH% SET PATH=%JAVA_HOME%\bin;%PATH%

Posted by: why Posted on: 2004-09-02 09:19 无论如何，阁下试过在COMMAND PROMPT上，依敝人的建议设定环境和执行程序没有？有没有试过重装J2SDK？ >> 请中文跟我教我，我不懂英语。这样的中文敝人也是看不懂的说。

Posted by: mingfanli Posted on: 2004-09-02 16:14 我的JDK才47M，和SUN官方网上的不一样，所以我在试着重新下JDK，看结果如何，谢谢版主！

Posted by: mingfanli Posted on: 2004-09-02 22:02 呵呵，终于调通了。我重新下了JDK1.4.2_05. 在安装的时候把所有的进程,如杀毒,防火墙之类的东西都关掉了.然后把环境变量设好,结果就编译通过了... 很感谢斑竹..........
