还是关于路径的问题，请各位帮忙，小妹谢谢各位

[rain_ok]

首先，我将环境变量改了，CLASSPATH是
.;d:\JDK1.3\lib\tools.jar;d:\tomcat\lib\common\servlet.jar;d:\jdk1.3\bin\Opta2000\Opta2000.jar;
PATH是
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;D:\jdk1.3;D:\jdk1.3\bin;D:\MSSQL7\BINN;（前面是系统的）
其次，我把ClassicDriver.java文件直接放在D:\JDK1.3\bin\ClassicDriver.java
接着，我开始编译和执行，编译D:\JDK1.3\bin>javac ClassicDriver.java
执行D:\JDK1.3\bin>java ClassicDriver,出错，显示
Exception in thread "main" java.lang.NoClassDefFoundError: ClassicDriver (wrong name:sample/ClassicDriver)
at java.lang.ClassLoader.defineClass0(NativeMethod)
at java.lang.ClassLoader.defineClass (ClassLoader.java:486)
at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:111)
at java.net.URLClassLoader.defineClass(URLClassLoader.java:248)
at java.net.URLClassLoader.access$100(URLClassLoader.java:56)
at java.net.URLClassLoader$1.run(URLClassLoader.java:195)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:188)
at java.lang.ClassLoader.loadClass(ClassLoader.java:297)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:286)
at java.lang.ClassLoader.loadClass(ClassLoader.java:253)
at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:313)
若是将文件放在D:\JDK1.3\bin\sample\ClassicDriver.java
执行出错信息是
Exception in thread "main" java.lang.NoClassDefFoundError: d:\jdk1.3\bin\sample\ClassicDriver
用java -classpath . ClassicDriver来运行，出错信息和D:\JDK1.3\bin>java ClassicDriver是一样的。
请各位指点迷津，小妹在此谢谢各位

代码帖了。为何没有人帮忙啊。我赶设计的，麻烦大家了。小妹在此谢谢大家

[dylanwolf]

把 package sample 去掉试试。

[zhjx_10]

将编译好的class放在sample目录下面看看

[zhjx_10]

代码贴出来

[可乐加水]

对，没有代码很难说清楚的

这是一个JDBC DRIVER （OPTA2000）下面的SAMPLE中测试数据库连接的JAVA文件。谢谢各位

[Times2001]

把class放到sample里面
然后用java sample.ClassicDriver
就可以了

[Times2001]

或者在程序中去掉package sample;

[rain_ok]

去掉package sample;的方法我试了，不可以，请问是应该用啥语句执行？谢谢

[qlqllu]

如果没有ctrl-c ctrl-v 大家还会不会把大段的代码写在这/？

[CHARGING]

把文件放到d:\tomcat\webapps\examples\WEB-INF\classes\Sample\目录下试试看.

[Times2001]

去掉package sample;不会不可以吧？
你去掉后重新javac java
我试过，可以的
不然就不去掉那句，直接把.class放到sample里面
然后用java sample.ClassicDriver
就可以了

[jiach]

又没有搞错，
你的问题比我迟发两分钟，却有这么多人捧场，我的问题和你挨着却没人回复，难道IT这么缺妹妹呀！！！
