Not able to download PDF file using java api for azure

How can I download pdf file from azure file storage. I know that there is a method downloadText() but it corrupts the pdf file. I have written code to download a uploaded file on azure and I have used downloadText() method but it's not working here.

However it downloads the pdf file but it says file corrupted or damaged.

Code sample which I am trying to do:

CloudFileDirectory sampleDir = rootDir.getDirectoryReference(path);
                        //Get a reference to the file you want to download
                        CloudFile file = sampleDir.getFileReference(fileStorageBean.getUniqueFileIdentifier());
                        //get file contents from azure file.
                        String fileContent = file.downloadText();
                        ESAPI.httpUtilities().setHeader(response, "Content-Disposition","attachment;");

                        response.setContentType(fileStorageBean.getMimeType());
                        response.setContentLength(file.getStreamWriteSizeInBytes());
                InputStream in = new ByteArrayInputStream(fileContent.getBytes());

You could use file.downloadToFile method to download your pdf file from Azure File Storage to local.

Sample Code:

CloudStorageAccount storageAccount = CloudStorageAccount.parse(storageConnectionString);

CloudFileClient fileClient = storageAccount.createCloudFileClient();

CloudFileShare share = fileClient.getShareReference("test");

CloudFileDirectory rootDir = share.getRootDirectoryReference();

CloudFile file = rootDir.getFileReference("testFile.pdf");

File sourceFile = new File("E:\\AzureFile\\f.pdf");

file.downloadToFile(sourceFile.getAbsolutePath());

Or you could use file.download method to download file to a stream.

OutputStream outs=response.getOutputStream();

file.download(outs);

Hope it helps you.
