My code: String inputFilename = cs.getInternalFilename(inputDocument); FileInputStream in= new FileInputStream(new File(inputFilename));en-USTelligent Community 12https://community.appian.com/thread/4161?ContentTypeID=1Mon, 16 Sep 2013 14:32:41 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:4e877691-a529-4393-a009-43fd90dcc0ffSathya SrinivasanOkay, couple of things to test. Since you&#39;re telling me that you have independently tested this and it works, I would assume that the issue is retrieving the content from CS. Let&#39;s do this. <br />First, check that you&#39;re injecting the content service and setting the value in the constructor. Next, put logging and find out what the cs holds and also check what cs.getinternalversion.... etc., returns. <br />When you retrieve a document, it will return an Array. Ensure you get document[0] and put a log around this to ensure that the values are coming through. <br />Let&#39;s see what the log says and take it from there.<div style="clear:both;"></div>https://community.appian.com/thread/4160?ContentTypeID=1Mon, 16 Sep 2013 14:25:04 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:c31972b7-2427-4cd4-8681-094074d5b6cchrishikeshdYa. I am exactly doing this . cs in my example is nothing but a content service.<div style="clear:both;"></div>https://community.appian.com/thread/4159?ContentTypeID=1Mon, 16 Sep 2013 14:02:40 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:dcf1d06a-127d-451d-99ad-2d5f201dc686Sathya SrinivasanYou will need ContentService to access the Appian Document from DMS. Make sure that the user has correct privileges for this otherwise you&#39;ll end up with Access violation.<br /><br />Here is an example code:<br />CS = ContentService. You have this injected automatically in your constructor. <br />String documentPath = cs.getInternalFilename(document_input);<br />FileInputStream fis = new FileInputStream(documentPath);<div style="clear:both;"></div>https://community.appian.com/thread/4155?ContentTypeID=1Mon, 16 Sep 2013 10:19:30 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:9539c9c6-6608-453f-a94d-73a29320d7d7hrishikeshd...Document. I am passing the name of the file which is to be converted<br />and according to error Object type is wrong . so how to access the file on the apian in this scenario ?? or what should be done in this scenario ? Any suggestions ?<div style="clear:both;"></div>
