Question

这是我的JSP代码：

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
 <%@ page import="com.lowagie.text.DocumentException" %>
 <%@ page import="org.xhtmlrenderer.pdf.ITextRenderer" %>
 <%@ page import="java.io.FileNotFoundException" %>
 <%@ page import="java.io.FileOutputStream" %>
 <%@ page import="java.io.IOException" %>
 <%@ page import="java.io.File" %>

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<%

final ITextRenderer iTextRenderer = new ITextRenderer();
iTextRenderer.setDocument("http://localhost:8080/MyApp/test.jsp");
iTextRenderer.layout();
final FileOutputStream fileOutputStream =new FileOutputStream(new File("invoice.pdf"));
iTextRenderer.createPDF(fileOutputStream);
fileOutputStream.close();
%>

</body>
</html>

当我运行时，我得到错误.. 。

这是完整的堆栈跟踪......

如何解决错误？

Answer 1

这是错误：

XRRuntimeException：无法实例化任何SAX 2解析器，包括 JDK默认。应该读取要使用的类的名称 org.xml.sax.driver系统属性，设置为：

解决方案是定义org.xml.sax.driver。例如，下载Xerces并在Tomcat中设置此JVM选项（或者您正在使用的任何内容）：

-Dorg.xml.sax.driver=org.apache.xerces.parsers.SAXParser
