How to access session/cookies/request in pageEvent? (Confluence plugin)

[Mai Hữu]

Hi every Body!

I intergrated jira, confluence, crowd. (Using SSO).

In my confluence plugin, I handle page event. In page event, I want to create JIRA issue using SSO authentication(Crowd).

So, how to access session/cookies/request in pageEvent?

I tried with 

ServletActionContext.getRequest(); 

but it alway return null value.

Thanks for your help!

@Mai Hữu i suggest you to use ApplicationLink to do the Jira comment from Confluence plugin https://developer.atlassian.com/server/framework/atlassian-sdk/application-links/
