Question

jsp中调用java代码里面的方法没有效果

<%
Test.output();
%>
<%
Test.input();
%>这是jsp中的调用

public static void output() throws FileNotFoundException, IOException {
ObjectOutputStream oop = new ObjectOutputStream(new FileOutputStream(new File("student.txt")));
oop.writeObject(map);
oop.close();
}

@SuppressWarnings("unchecked")
public static void input() throws ClassNotFoundException, IOException {
ObjectInputStream oip = new ObjectInputStream(new FileInputStream(new File("student.txt")));
Object obj;
obj = oip.readObject();
if (obj instanceof HashMap) {
map = ((HashMap<Integer, Student>) obj);
}
oip.close();
}这是java中的源代码，我用main进行了测试，是可以创建Student.txt.
jsp中调用不了这个两个方法

估计你是找不到文件创建到哪去了
去TOMCAT的bin目录找找看
