利用openoffice把office转成pdf，组件无法使用，请各位大侠帮忙。

function MakePropertyValue($name,$value,$osm){  	$oStruct = $osm->Bridge_GetStruct("com.sun.star.beans.PropertyValue");  	$oStruct->Name = $name;  	$oStruct->Value = $value;  	return $oStruct;  }function word2pdf($doc_url, $output_url){  	$osm = new COM("com.sun.star.ServiceManager") or die ("Please be sure that OpenOffice.org is installed.n");  	$args = array(MakePropertyValue("Hidden",true,$osm));  	$oDesktop = $osm->createInstance("com.sun.star.frame.Desktop");  	$oWriterDoc = $oDesktop->loadComponentFromURL	($doc_url,"_blank", 0, $args);  	$export_args = array(MakePropertyValue	("FilterName","writer_pdf_Export",$osm));  	$oWriterDoc->storeToURL($output_url,$export_args);  	$oWriterDoc->close(true);  }$output_dir = "D:/APMServ5.2.6/www/htdocs/pdf/";  $doc_file = "D:/APMServ5.2.6/www/htdocs/doc/abc.doc";  $pdf_file = "abc.pdf";  $output_file = $output_dir . $pdf_file;  $doc_file = "file:///" . $doc_file;  $output_file = "file:///" . $output_file;word2pdf($doc_file,$output_file);
