Attach a file to jira from Java API using a stream

[Gil Brown]

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);
blob.free();
String folder ="/home/atlassian/application-data/SBMAttachments/";
File tempFile = new File(folder+filePrefix + fileName);
 
FileOutputStream fos = new FileOutputStream(tempFile);
fos.write(blobAsBytes);
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();
 builder.file(file);
 builder.filename(file.getName());
 builder.contentType(mm.getSuggestedMimeType(filename));
 builder.author(user);
 builder.issue(issue);
 builder.copySourceFile(true);
 CreateAttachmentParamsBean bean = builder.build();
 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();
 //attachmentManager.createAttachment(bean);
 //LOG.error("created!");
 }
 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 ?

Hi! 

Looks like this thread will help for you

Thanks, I already resolved it with the file system .

[Gonchik Tsymzhitov]

May I know the full use case? 

Looks like you have developed a custom attachment uploader. 

Is that correct?

[Shye Wilkanski]

Yes, We had old system (SBM) and we needed to migrate the issues from there to our JIRA.

SBM saved the attachments data as BLOB's in the DB and I wanted to take the stream of BLOB and save it directly to the issue.

eventually I saved the BLOB on the JIRA machine as Files and then attaching this file to the issue.
