I am using a web service that helps me to fetch files from a message hub. File type can either be XML or ZIP.
For ZIP files, the content type is binary.
I have this piece of code :
private String extractPayload(String filePath, AttachmentPart attach){
FileOutputStream fileStream = null;
try {
DataHandler handler;
handler = attach.getDataHandler();
File f = new File(filePath);
fileStream = new FileOutputStream(filePath);
handler.writeTo(fileStream);
fileStream.flush();
} catch (Exception ex) {
logger.info("####Exception:" + ex.getMessage());
} finally {
if (fileStream != null)
fileStream.close();
}
return filePath;
}
Now, the code works fine for fetching XML files, although, in case of ZIP files, the file turns out to be corrupt. I downloaded the same file using file utility from the Messaging Hub and found out that the Size of File that i fetch through SOAP Attachment is around 4 bytes more then its actual size.
Update : The attachment encoding is 7-Bit (if that might be obstructing) while another attachment containing another zip is encoded Quote-printable. Both the zips are being fetched from same web service (although they differ in encoding), and both turn out corrupt.
Edit: I strongly feel that the problem is with the encoding in which i am receiving file and here is a comparison between the actual file and the received attachment file.
Actual File size : 9031 bytes Received Attachment File size : 9066 bytes
I tried comparing both files in a document editor to find the differences between both. Original file to fetched attachment file differences (Binary editor):
ed changed to 3f , db changed to 3f , d6 changed to 3f , 85 changed to 3f , d0 changed to 3f ,
and so on.
Zip file contains a PDF and an XML file.
The start line of both files are similar, starting with PK
