You can login to the REST api using standard http connection techniques. For
instance basic auth you can login doing the following:
http://<user>%40<domain>:<password>@<engine_host>/ovirt-engine/api
Will list the available REST api.
But I am still not clear on what you are trying to do. Are you trying to write
your own external servlet, that calls the REST api to do things for you? Or
are you trying to write a servlet that lives inside the context of the engine
and implements a new action?
Also please reply all, so we can keep the discussion on the mailing list so
other people can find it in the future.

New subject: How To Auto Set oVirt RESTApi Session？
I'm sorry I did not explain my needs clearly.
In my case,I want to redesign the WebAdmin login GUI and add some
javascript in my WebAdmin login page to do many own logic.At present I
don't know how to add javascript in gwt framework,so I have to make a
servlet to alternative the original WebAdmin login GUI.
After admin user log in the WebAdmin Portal through my servlet,UIPlugin
which use restapi to get data in the portal cannot automate get the
user's certificate,the uiplugin show me a prompt to input the username and
password.
I am looking forward to your guide!
Thanks!
Best regards!

Okay so if I understand correctly there are 2 parts to your issue.
1. You want an alternate login screen for which you wrote your own servlet
that displays your login screen.
2. You have a UI plugin that needs the rest api credentials to make calls to
the REST api.
- For 1, A consequence of what you are describing to me, is that you will need
to compile and package ovirt with your custom extension yourself. Which may
potentially break if we ever make changes to the code. I highly suggest you
keep an eye out for the SSO capability we are working on in 3.6. But for now I
guess you can do the following, which can and probably will break with each
version of ovirt.
The source code for the login window in webadmin is in:
rontend/webadmin/modules/webadmin/src/main/java/org/ovirt/engine/ui/webadmin/section/login/presenter
and view. You can alter it whatever way you want to do your custom stuff.
However this requires you to know GWT.
If you want to do the servlet approach:
look in
frontend/webadmin/modules/frontend/src/main/java/org/ovirt/engine/ui/frontend/server/gwt/GenericApiGWTServiceImpl.java
at the login and logOff methods. Do something similar to that in your servlet
when you submit the form from your servlet. After you login, you can redirect
the browser to the webadmin URL, at that point it should recognize you are
logged in and show the webadmin while bypassing the original login screen.
This will work if you servlet lives in the same context as the webadmin
servlet.
Again, both of these approached will probably work, but depend on internal
code which can and will change over time, so you will have to maintain your
code to match. When the SSO capability is fully rolled out you should be able
to write your own login screen that doesn't depend on internal structures
which will make maintaining that much easier for you. I believe this is
scheduled for the 3.6 timeframe.
- For 2, in your UI plugin, you need to hook into the RestApiSessionAcquired
event. Its use is described here [1]. You can pass the session id in that
event as a header to your request to the REST api and that makes the requests
succeed. Examples of code that do that are available in the sample UI plugins
on that page.
