Attach a file to jira from Java API using a stream

I'm trying to add attachment from input stream or byte array .



I have the following code:


Blob blob = rset.getBlob(12);

int blobLength = (int) blob.length();
byte[] blobAsBytes = blob.getBytes(1, blobLength);;
String folder ="/home/atlassian/application-data/SBMAttachments/";
File tempFile = new File(folder+filePrefix + fileName);

FileOutputStream fos = new FileOutputStream(tempFile);
addAttachmentToJira(tempFile,issue, fileName,user);
public static boolean addAttachmentToJira(File file,Issue issue,String filename,ApplicationUser user) throws Exception{
MimeManager mm = new MimeManager(new FileInputStream(file));

AttachmentManager attachmentManager = ComponentAccessor.getAttachmentManager();
CreateAttachmentParamsBean.Builder builder = new CreateAttachmentParamsBean.Builder();
CreateAttachmentParamsBean bean =;
com.atlassian.fugue.Either<AttachmentError,ChangeItemBean> result = attachmentManager.tryCreateAttachment(bean);
if (result.isLeft()) {
AttachmentError attachmentError = (AttachmentError) result.left().get();
//LOG.error("AttachmentError '" + attachmentError.getLogMessage());
} else {
ChangeItemBean changeItemBean = (ChangeItemBean) result.right().get();
return true;


My idea is to add the attachment without saving the file (to save time).

Is there a way to add the attachment from input stream ?
