        //Invoke the OpenOffice.org service manager
        $osm = new COM("com.sun.star.ServiceManager") or die ("Please be sure that OpenOffice.org is installed.\n");

        //Launch the desktop
        $top = $osm->createInstance("com.sun.star.frame.Desktop");
        //Load the .doc file, and pass in the "Hidden" property from above
        $oWriterDoc = $top->loadComponentFromURL($doc_url,"_blank", 0, $args);
        //Set up the arguments for the PDF output
        $export_args = array($this->MakePropertyValue("FilterName","writer_pdf_Export",$osm));

登录后复制

错误：Fatal error: Uncaught exception 'com_exception' with message 'Failed to create COM object `com.sun.star.ServiceManager' in "the project of path"



------解决方案--------------------
需要安装OpenOffice.org
------解决方案--------------------
1、检查一下是否安装过OpenOffice。
2、用命令行启动OpenOffice服务：
cd C:\Program Files\OpenOffice.org 3\program
C:\Program Files\OpenOffice.org 3\program>soffice -headless -accept="socket,host
=127.0.0.1,port=8100;urp;" -nofirststartwizard
然后再试验一下呢.
