I have to upload documents from web application into alfresco document library, for that i have written my code using openCMIS. My code is working perfectly, the documents are uploaded successfully in document library but when i lick on that document its preview is not working. It is <em>showing preview cannot be loaded from server </em>
can anyone help me with this issue?

Almost certainly your conversion is failing. You will find the error in alfresco.log. Very often this is a memory issue that will be temporarily cleared by a restart but you may need to allocate more memory / have more memory.

Don't know what CMIS wrapper you are using, but I have used the PHP one before now. Below is the code that checks to see if a document is in the document library of a given site and if is it it will call a function to update some of the metatdata (that function isn't in the snippet).
In this example, the file name I am looking for is the site short name with an extension of XML (e.g. if the site short name was an-employee, then I would be looking for an-employee.XML)
function setMetaData($siteName, $empData, $getVar, $siteDescription, $sessionID, $empLocation) { $retVar = true; $ch = curl_init(); $url = "localhost:8080/alfresco/service/farthest-gate/get-notice/site/"; $url .= $siteName . "/documentLibrary?output=nodeonly&docname=" . $siteName . ".XML"; curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC); curl_setopt($ch, CURLOPT_USERPWD, $getVar); curl_setopt($ch, CURLOPT_HTTPGET, TRUE); curl_setopt($ch, CURLOPT_HEADER, FALSE); curl_setopt($ch, CURLOPT_HTTPHEADER, array("Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8")); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); curl_setopt($ch, CURLOPT_TIMEOUT, '3'); $response = curl_exec($ch); curl_close($ch); // Response SHOULD be a JSON response try { $or = json_decode($response); if(!@$or->items[0]->nodeRef) { echo "Site XML file not found\r\n"; $retVar = false; } else { $jsonPost = $this->setJSON($empData, $empLocation); $ch = curl_init(); $nodeRef = str_replace("://", "/", $or->items[0]->nodeRef); $url = "localhost:8080/share/proxy/alfresco/api/node/" . $nodeRef . "/formprocessor"; curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HEADER, FALSE); $sessionCookie = sprintf("JSESSIONID=%s",$sessionID); curl_setopt($ch, CURLOPT_COOKIE, $sessionCookie); $headerOptions[0] = "Content-Type: application/json"; $headerOptions[1] = "Accept: application/json"; $headerOptions[2] = "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"; $headerOptions[3] = "X-Requested-With: application/x-www-form-urlencoded"; curl_setopt($ch, CURLOPT_HTTPHEADER, $headerOptions); curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonPost); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); $response = curl_exec($ch); curl_close($ch); // Response SHOULD be a JSON response try { $or = json_decode($response); if($or == NULL) { echo "Alfresco service returned invalid JSON $response\r\n"; $retVar = false; } else { if(@$or->message) { if(strpos($or->message,"Successfully persisted form") === FALSE) { echo "Alfresco service returned error $or->message\r\n"; $retVar = false; } else { echo "Employee metadata for $siteName ($siteDescription) updated\r\n"; } } else { echo "Alfresco service did not update metadata responded with $response\r\n"; $retVar = false; } } } catch (Exception $e) { echo "Request returned invalid JSON. response: ". $repsonse . " Exception: ". $e.getMessage() . "\r\n"; $retVar = false; } } } catch (Exception $e) { echo "Failed to update metadata ". $e.getMessage() . "\r\n"; $retVar = false; } return $retVar; }

Do you mean "How do I use CMIS to get the metatdata associated with a document?"

Not sure how good your PHP is, but below is an edited script that I wrote that will retrieve the metadata associated with all documents of a given type and write it into a csv file.
Its basically an SQL query so you can adjust that to search on document name, noderef or anything else really.
