How to get atlassian token using java

[Harinath T]

Hi

Can anyone please guide me how we can get atlassian token. 

I want to update transition from the external application with the workflow transition screen which we created in Jira. 

we want to show Jira screens in an external application. So I have tried with iframe but unable to perform form handling like hiding footer / header, and when the user clicks on form submit it has to return external application.

Can we do form handling using atlassian token? if yes how can I get this token using java program, Or is there any alternate way to get Jira screens into external application.

I also used InputStreamReader to get the screen content by using Basic Authentication but here also I am facing issues with the XSRF Security Token Missing error.

Finally, can I achieve presenting screen into external application using atlassian token.

Thanks You
