我有一个示例测试 PHP 页面和 Jasper 报告。我在导出到 PDF 步骤时遇到错误：

服务器设置：

java version "1.7.0_06"
Java(TM) SE Runtime Environment (build 1.7.0_06-b24)
Java HotSpot(TM) 64-Bit Server VM (build 23.2-b09, mixed mode)
php PDF library  PDFlib-Lite-7.0.5p3
php-java-bridge_6.2.1
jdk-7u6-linux-x64.rpm
apache-tomcat-7.0.29

我试过了：

CATALINA_OPTS="-Djava.awt.Headless=true

我有一个类似的生产服务器，具有相同的上述设置，我可以从我的 PHP 网站运行碧玉报告。

PHP 文件：
