"Frame1.java": Error #: 475 : class ConnectionTest is public; must be declared in a file named ConnectionTest.java at line 7, column 8指向的是public class ConnectionTest
是什么意思？
菜鸟求教，我在自己的机子上装的是jbuilder5用的是jdk1.3，在ｊｄｋ1.3\jre\lib下没有ext，我把jdbc驱动classes12.zip考到jbuilder5/安装的根目录下行吗？
将驱动放到哪里无所谓，关键是要让classpath去指向
