Question

这是我的xml文件：

<?xml version= "1.0" encoding = "windows-1251"?>
 <!DOCTYPE jasperReport 
 PUBLIC "-//JasperReports//DTD Report Design//EN"
 "http://jasperreports.sourceforge.net/dtds/jasperreport.dtd" >
<jasperReport name = "first">
<style 
 name = "Base"
 isDefault = "true"
 hAlign = "Center"
 vAlign = "Middle"
 fontName = "Arial"
 pdfFontName = "C:\Windows\Fonts\arial.ttf"
 pdfEncoding = "Cp1251"
 isPdfEmbedded = "true"
 fontSize = "10"
 />
<field name = "Faculty_Name" class = "java.lang.String" />
<field name = "StudSurname" class = "java.lang.String" />
<detail>
<band height = "20" >
<textField>
 <reportElement  x = "100" y = "0" width = "100" height = "20" />
  <textFieldExpression class = "java.lang.String" >
   <![CDATA[$F{Faculty_Name}]]>
  </textFieldExpression> 
</textField>
<textField>
 <reportElement  x = "200" y = "0" width = "100" height = "20" />
  <textFieldExpression class = "java.lang.String" >
   <![CDATA[$F{StudSurname}]]>
  </textFieldExpression> 
</textField>
</band>
</detail>
</jasperReport>

这是我的代码：

try {

            String configFileText = JasperConfigMaker.getConfig(columnList, "first");
            File configFile = new File("jasper.jrxml");
            configFile.createNewFile();

            FileWriter writer = new FileWriter(configFile);
            BufferedWriter buffered = new BufferedWriter(writer);
            buffered.write(configFileText);
            buffered.flush();
            buffered.close();
            writer.close();
            System.setProperty("org.xml.sax.driver", "org.apache.xerces.parsers.SAXParser");
            JasperReport jasperReport = JasperCompileManager.compileReport("jasper.jrxml");
         //   configFile.delete();

           // JasperPrint jasperPrint = JasperFillManager.fillReport( jasperReport,  new HashMap(), new JRResultSetDataSource(reportData));
          ///  JasperExportManager.exportReportToPdfFile(jasperPrint, "reports/" + pdfFileName);


        } catch (Exception e) {
                e.printStackTrace();
        }

我得到例外：

请帮我理解原因。我在一小时内对抗这个错误。它也很有趣，它不是在Eclipse中编译，而是在IDEA中编译。有任何想法吗？谢谢。

Parser不喜欢您的SmbFile作为架构源。看一下SmbFile的文档：
