到目前为止,我只有一个工作代码,用于从ppt幻灯片笔记中检索文本

try {
    FileInputStream is = new FileInputStream("C:\\sample\\test.ppt");
    SlideShow ppt = new SlideShow(is);

    Slide[] slide = ppt.getSlides();
    for (int i = 0; i < slide.length; i++) {

        System.out.println(i);
        TextRun[] runs = slide[i].getNotesSheet().getTextRuns();
        if (runs.length < 1) {
            System.out.println("null");
        } else {
            for (TextRun run : runs) {
                System.out.println(" > " + run.getText());
            }
        }
    }

} catch (IOException ioe) {

}

但是如何从pptx幻灯片笔记中检索文本？

我正在尝试基于播放框架示例'zentask'创建一个登录页面.

当我尝试在登录页面中提交表单时,user_name和user_pass为null.

命令提示输出:

[info] play - database [default] connected at jdbc:mysql://localhost/smgts2
[info] play - Application started (Dev)
null null

Application.java:

package controllers;

import play.*;
import play.mvc.*;
import play.data.*;
import static play.data.Form.*;

import models.*;
import views.html.*;

public class Application extends Controller {

    // -- Authentication

    public static class Login {

        public String user_name;
        public String user_pass;

        public String validate() {
            if(Accounts.authenticate(user_name, user_pass) == null) {
                return "Invalid user or password";
            }
            return null;
        }

    }

    /**
     * Login page.
     */
