Question

我想使用命令按钮从xhtml页面创建pdf，但是在浏览器中，resault是一个黑色的空白页面，我已经搜索了网页，但没有找到像我的情况。我正在使用：xhtmlrenderer-1.0.0.jar - Maven projet

PrintBean.java

PUT

test.xhtml

axios.post('https://projectname.firebaseio.com/padres/user_one.json', padre)

要打印的页面，print.xhtml

    package com.ismo.gestionabsence.presentation;

import java.io.File;
import java.io.OutputStream;
import java.io.Serializable;
import java.net.URL;
import java.util.Date;

import javax.annotation.PostConstruct;
//import javax.enterprise.context.SessionScoped;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.context.ExternalContext;
import javax.faces.context.FacesContext;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession; 

import org.docx4j.org.xhtmlrenderer.pdf.ITextRenderer;

@ManagedBean(name = "printBean")
@SessionScoped
public class PrintBean implements Serializable  {



    /**

     */
    private static final long serialVersionUID = 1L;

    private int     code;
    private String client;


    public PrintBean()
    {}

        @PostConstruct
        public void init()
        {

            code=1;
            client="teste de client;";
        }








    public int getCode() {
        return code;
    }

    public void setCode(int code) {
        this.code = code;
    }


    public String getClient() {
        return client;
    }

    public void setClient(String client) {
        this.client = client;
    }

    public void createPDF()  {

        System.out.println("in");
        FacesContext facesContext = FacesContext.getCurrentInstance();
        ExternalContext externalContext = facesContext.getExternalContext();
        HttpSession session = (HttpSession) externalContext.getSession(true);
        String url = "http://localhost:8080/simple-webapp/faces/print.xhtml;jsessionid="+session.getId()+"?pdf=true";
        System.out.println("url");
        try {

            ITextRenderer renderer = new ITextRenderer();
            renderer.setDocument(new URL(url).toString());

        //  renderer.setDocument(new File(url));
            renderer.layout();
            HttpServletResponse response = (HttpServletResponse) externalContext.getResponse();
            response.reset();
            response.setContentType("application/pdf");
            response.setHeader("content-Disposition", "inline: filename=\"facture.pdf\"");
            OutputStream outputStream = response.getOutputStream();
            renderer.createPDF(outputStream);

        } catch (Exception e) {
            e.printStackTrace();
        }
        facesContext.responseComplete();
    }
    public void test()
    {System.out.println("test");}

}

堆栈错误：

如果有人可以谴责如何解决这个问题，我将不胜感激！问候，原谅我的英语!! 一张图片来解释更多情况：the pdf is empty

无法从xhtml（xhtmlrenderer-1.0.0.jar）生成pdf
