Not able to send mail with attachment by mailgun api

[Edunext Jain]

I am building Appengine application using JAVA

I am using mailgun api for mail.
I have some HTML content which I want to send as attachment, Please help me out to do so, as FileDataBodyPart takes object of java.io.File which I am unable to create as per Appengine's restriction.

Also I have some files stored on Google Storage and not able to send as attachment due to same above mentioned reason.

Hey Edunext,

I'll reproduce the comment I left on the Public Issue Tracker thread which it appears was created parallel to this thread:

File objects are excluded from use in App Engine Standard Environment apps, although you have two options here:

* Put a URL to the bucket object into the email

* Use the Flexible Environment to deploy an app which can read use File objects

This issue will close as WorkingAsIntended, since it's not a platform issue but a specific issue technical support question which has an existing answer available through a search of the documentation or Stack Overflow. Feel free to use this forum in future to report platform issues. If you'd like to ask a specific technical support question, post it to Stack Overflow, or if you have a more general question, feel free to post to the Google Groups forum for App Engine [1].

As a more general response, please make sure to only post in the most relevant forum. In this case, this forum was the correct place to post.

Cheers!
