到新公司導入的新項目；
環境eclipse是3.4，jdk是1.5，tomcat是5.5的，現在看來是有點老了。
導出jar包時報錯如下：

網上有一些方法，我的是發現放classes文件夾中並沒有編譯的內容。classes文件夾位置如下：
正常的話部署好tomcat和jdk后，classes中都會有編譯的文件，而且是自動編譯的。
我發現我這里面沒有東西，我又設置了一下eclipse的自動編譯：如下勾選build ----，然后clean，然后重啟eclipse。但是還沒有classes文件。
最后，我由刪除了項目，重新導入了一次，classes里面有內容了。
不報錯了，但是解決方法沒有弄明白，各位提示一下。
