【问题描述】：
我正在使用 symfony 2 php 构建一个 Web 应用程序。我想使用 jasperreports 生成一些报告。我使用了 Java Bridge，并且在我的 tomcat 7 中部署了 Java bridge war，但是当我尝试生成报告时遇到错误。
这是我的控制器中的代码
require_once("http://localhost:8080/JavaBridge/java/Java.inc");
$reportsPath ="D:/jaspertest/";
$reportFileName = "report";
$jasperReportsLib = "D:/Programmes/jasperReport/lib";
$java_library_path = '';
$handle = @opendir($jasperReportsLib);
while(($new_item = readdir($handle))!==false) {
$java_library_path .= 'file:'.$jasperReportsLib.'/'.$new_item .';';
}
java_require($java_library_path);
$sJcm = new JavaClass("net.sf.jasperreports.engine.JasperCompileManager");
$report = $sJcm->compileReport($reportsPath .$reportFileName.".jrxml");
$map = new Java("java.util.HashMap");
$emptyDataSource = new Java("net.sf.jasperreports.engine.JREmptyDataSource");
$sJfm = new JavaClass("net.sf.jasperreports.engine.JasperFillManager");
$print = $sJfm->fillReport($report,$map,$emptyDataSource);
$sJem = new JavaClass("net.sf.jasperreports.engine.JasperExportManager");
$sJem->exportReportToPdfFile($print, $reportsPath .$reportFileName.".pdf");
set_time_limit(0);
@readfile($reportsPath .$reportFileName.".pdf");// or die("problem occurs.");
$response = new Response($reportsPath .$reportFileName.".pdf");
$response->headers->set('Content-type', 'application/pdf');
$response->headers->set('Content-Disposition', 'attachement; filename=Report.pdf');
$response->headers->set('Cache-Control', 'must-revalidate');
return $response;
这是我得到的例外：

我到处寻找，但找不到解决方案，是我遗漏了什么吗？
