我不知道你说的错误是什么呀。

D:\Builder2006\jdk1.5\bin\javaw -classpath

"C:\Documents and Settings\A1\jbproject\cuo\classes;D:\Builder2006\jdk1.5\lib\dt.jar;D:\Builder2006\jdk1.5\lib\tools.jar;D:\Builder2006\jdk1.5\lib\htmlconverter.jar;D:\Builder2006\jdk1.5\jre\lib\ext\dnsns.jar " Welcome

==> 按照你说的，上面这一段是你指的错误信息吗？
