用OPENOFFICE转换文件格式的问题

我在网上下了一段代码，但是运行的时候出错。请教下怎么回事？谢了。

错误是：
Fatal error: Uncaught exception 'com_exception' with message 'Failed to create COM object `com.sun.star.ServiceManager': 服务器运行失败 ' in E:\Web\doc.xidian.cc\pdf.php:10 Stack trace: #0 E:\Web\doc.xidian.cc\pdf.php(10): com->com('com.sun.star.Se...') #1 E:\Web\doc.xidian.cc\pdf.php(25): word2pdf('file:///upload/...', 'file:///upload/...') #2 {main} thrown in E:\Web\doc.xidian.cc\pdf.php on line 10
