Both the apps use same username and password, i need to authenticate app1 from app2 and have the a开发者_如何学编程uthentication results in a securitycontext. I have searched, but couln't find much info. Have some across similar scenario?? Any information will be highly appreciable.

Sounds like you need a single sign on solution. Apache Shiro has some basic SSO capabilities, but for a more robust tool you should check out JOSSO.

Spring also support integration with Central Authentication Service (CAS).

There is an extension for SAML.

And another extension for OAuth.

Any of them could give you autentication across multiple apps.
