Hi Alejandro Thanks for your reply.
Thanks for your valuable time that you have spent here. I hope you will spent some more time to solve my problem. Before going to write the code I am going to describe you what it is toady and what I want to achieve. I have an java web application which run on a different server (e.g Tomcat). All the media files (.mp3) which are uploaded to Google cloud Storage,are present in that server and easily assessable from server side code from my web application. When user click on a button in my application, my web app first search for that media file in specific path and if found then web app try to connect Google Cloud Storage with java client and upload this media file to the specific bucket. I want to send this media file to the users from Google Cloud Storage using SendGrid. This is what I needed. I go through the link you have suggested. If I am not wrong, this attachments are just read the file from specific path (in my case server side) as Input stream and send it through the mail. no need to download this file from Google Cloud Storage. It is not dependent on SendGrid or jurssy. Just upload to GCS and send it from the local path. Can you please clarify. -Snahasish -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
