问一个JAVA编译的问题

[wzg7711]

开发环境是：jdk1.4、resin3.0.8,

C:\jdk1.4\bin>javac D:\resin\web\src\com\pixel\DBConn.java

编译的时候没有发现错误，怎么编译的时候DBConn.class这个怎么和DBConn.java在同一个文件夹呢，而不是在D:\resin\web\WEB-INF\classes\com\pixel文件夹呢，是不是环境变量没有设置好？

控制台编译显然class文件会和java文件在一个目录下

工程的部署就需要你自己把class和其他相关的包等移到web-inf下面，或者你用ide，自动帮你搞定了
像eclipse编译也顶多帮你把class放到class/package1/package2/XXclass.class
用myeclipse部署就会自动把相关内容移到webapp下（tomcat服务器）

看一下 javac -d 参数
