Class WSSubjectValidationImpl

java.lang.Object
  com.ibm.websphere.objectgrid.security.plugins.builtins.WSSubjectValidationImpl

All Implemented Interfaces:

SubjectValidation

public class WSSubjectValidationImpl
extends Object
implements SubjectValidation

This class is an implementation of the SubjectValidation interface in a WebSphere Application Server environment.

A typical scenario of using this class is described as below:

• The client has already been authenticated to WAS before it accesses ObjectGrid.
• The client is running locally on the ObjectGrid server side.
• The client retrieves the runAs Subject from the thread and passes the subject to ObjectGrid server.
• The ObjectGrid runtime will call the validateSubject(Subject) method to validate the subject has not been tampered with.

Here is the code sample:

 //get the subject from the thread 
 Subject subject = com.ibm.websphere.security.auth.WSSubject.getRunAsSubject();
 
 // use the subject to get a Session object 
 Session session = objectgrid.getSession(subject);
 

Since:

WAS XD 6.0
