Question

我想打印存储在数据库中的数据，我使用了ireport和jasperreport，我认为我的库有问题，这里是我下载的库列表：

 jasperreports-6.0.4.jar
 jasperreports-font-6.0.4.jar
 jasperreports-javaflow-6.0.4.jar
 barecode4j-2.1.jar
 commons-beanutils-1.9.0.jar
 commons-codec-1.5.jar
 commons-collections-3.2.1.jar
 commons-digester-2.1.jar
 commons-logging-1.1.1.jar
 iText-2.1.7.js2.jar
 com-jaspersoft-ireport.jar

data.html

<form action="Print">
<input type="submit" value="print">
</form>

的Servlet：Print.java

  private static Connection con;  
  PrintWriter out = response.getWriter();
   try{
  Class.forName("com.mysql.jdbc.Driver");
 con=DriverManager.getConnection("jdbc:mysql://localhost/test","root","");
 }catch(SQLException e){
 e.printStackTrace();
 }
  catch(ClassNotFoundException f){
  f.printStackTrace();
  }  
   try{
        JasperDesign jd= JRXmlLoader.load("list_user.jrxml");
      String sql ="select * from user";
       JRDesignQuery newQuery=new JRDesignQuery();
       newQuery.setText(sql);
       jd.setQuery(newQuery);
       JasperReport jasperReport =JasperCompileManager.compileReport(jd);
       JasperPrint jasperprint=JasperFillManager.fillReport(jasperReport,null,con);
       JasperViewer.viewReport(jasperprint);
   }catch(Exception e){
      System.out.println(e);
   }

我遇到了这个错误：
