Post attachments using REST API with java

[knut]

Hello,

I have a problem and need some help. I have two different instances of a JIRA application -> Jira1 and Jira2 (but they are directly connected with each other). For synchronization I want to synchronize/upload the attachments of an issue of jira1 to an issue of Jira2 (the attachments are only available on an issue of jira1).
Is it possible to upload the attachment from the issue of jira1 to the issue of jira2 using java REST API without using cURL? I dont want to download the files -> i want to use the directly connection for synchronization.

 Can someone post sample code?

Any help would be great.

Thanks

You'll need to find or write some code to do this.  (Curl is just one tool that performs web actions, you can use that or something else)
