Where is the subject stored?

Weblogic Subject propagation: where is the subject stored?

  • I need to understand how the subject is stored and propagated in Weblogic. Once authenticated, where is the subject stored at the HTTP layer? Internally, is it stored in HTTPSession? Same way, where is it stored at the EJB layer? I have an application where a lot of principals are updated in the subject at the HTTP and EJB layers. In some corner cases, I'm getting a concurrent modification exception. Although the fix is simple, just to synchronize, I need to understand the internals of where the subject is stored at the HTTP and EJB layers.

  • Answer:

    This refers to WebLogic implementation internals, which may even change from version to version so I would keep away from it. You will find official information just for the public http://docs.oracle.com/cd/E12840_01/wls/docs103/security/overview.html#wp1042212.
