Hello,

I need to send emails in java code using OAUTH2. I have got client Id and client secret from Google API Console[^] and trying to get authorization code at [^] from where I have found 3 tokens,

Authorization code

,

Refresh token

and

Access token

. When I replace Oauth token with authorization code or access token, I found error for invalid user id and password. I will be really thankful if someone can provide running example of javaMail using OAUTH2.
Some tutorials recommend using Python scripts, but I have no clue that weather it is possible to run python script in java and obtain output again in Java.
Thank you

What I have tried:

I have tried executing java code similar to
[^] but invalid user id and password error is displayed.

Solution 1

Have you tried Google's own Java Client Lib? I'll give you google java client api - Google Search[^] as it points to a number of key pages for you. Thier instructions and samples are very good.

Solution 2

I will try it also, but the java codes I was trying earlier to send emails were facing issues after deployment. I am using Amazon services for hosting of my web application and often mail requests are blocked by hosting server. Therefore I am searching for more secure method to send emails without any problem.
Thanks for your response

It may be an AWS configuration issue. I haven't used AWS, so I can't suggest what is required. I am sure they'll have information to help you.
