jsp调用类文件

            File[] fl = f.listFiles();
            out.putNextEntry(new ZipEntry(base + "/"));
            base = base.length() == 0 ? "" : base + "/";
            for (int i = 0; i < fl.length; i++) {

        }

    }

    public static void main(String[] args) {
        try {
            TestZip t = new TestZip();
            t.zip("D:/zip.zip", "D:/zip");
            t.unzip("D:/zip.zip", "D:/newZip");
        } catch (Exception e) {
            e.printStackTrace(System.out);
        }
    }

}

我把编译后的TestZip.class
放在WEB-INF/classes/com/hdpu\utility下了，也用import="com.hdpu.utility.*"引入了这个文件了，在jsp页面中
<%
TestZip t = new TestZip();
t.zip("D:/zip.zip", "D:/zip");
t.unzip("D:/zip.zip", "D:/newZip");
%>
一运行就出现错误
错误的类文件：......../TestZip.class
类文件包含错误的类：TestZip
请删除该文件或确保该文件位于正确的类路径子目录中。
TestZip t=new TestZip()
帮忙给看看吧，这是怎么回事？谢谢啦！

<% page import="com.hdpu.utility.*" %>
是不是这样导入的。看下冒号是否存在。？

就是这么导入的，我这种调用方法对吗？

我怎么没在你的。java里看到 package 呢？？？？？ 怎么回事？

[knightzhuwei]

难道楼主没在java文件里写package。。晕

呵呵,默认包下面调用不了
