Hi,
what do you get instead ? I used to work with a Firefox Plugin "PDF Download", but could not download PDFs with this plugin, which were coming from Alfresco. The authentification information got lost on the way and I always got a document with the correct name & extension, but with the "HTML Login.jsp" sourcecode as real content.

My only solution was to not use "PDF Download" so far.

The problem arises when i try to download my content using the convertToByteArray() metohd of ContentUtils:


Content content = contentResultArr[0];
InputStream inputSteam= ContentUtils.getContentAsInputStream(content);
byte [] contentByteArr = ContentUtils.convertToByteArray(inputSteam);
outFileContent.close();
‍‍‍‍‍‍

The InputStream that i receive is perfect (with say length=18k bytes) , but when i try to convert the input stream to byte array, the total byte size reduces to 16K. This happens with all the file formats(word/excel/pdf) with size greater than 16k bytes since the inputSteam.isAvailable() function used internally in convertToByteArray() return only 16k bytes at a time.

I got this rectified by using the getContentAsString() line :


Content content = contentResultArr[0];
String contentString= ContentUtils.getContentAsString(content);
byte [] contentByteArr = contentString.getBytes();
outFileContent.close();
‍‍‍‍‍‍

This solves the byte size prob.
However, now when trying to view the file, it gives memory error. :cry:

Temporarily, as a solution, I write the content onto the local system using
ContentUtils.copyContentToFile(content, file);
and read the content from the file using I/O stream.

If any one can help me read out the content directly from alfresco repository, through any other way besides ContentUtils let me know.

Sharon.
