Example: Overriding the RunAs Subject on the Thread

To extend the function provided by the Java Authentication and Authorization Service (JAAS) APIs, you can set the RunAs subject (or invocation subject) with a different valid entry that is used for outbound requests on this execution thread.

Gives flexibility for associating the Subject with all remote calls on this thread whether using a WSSubject.doAs() to associate the subject with the remote action or not. For example:

try
{
javax.security.auth.Subject runas_subject, caller_subject;

runas_subject = com.ibm.websphere.security.auth.WSSubject.getRunAsSubject();
caller_subject = com.ibm.websphere.security.auth.WSSubject.getCallerSubject();

// set a new RunAs subject for the thread, overriding the one declaratively set
com.ibm.websphere.security.auth.WSSubject.setRunAsSubject(caller_subject);

// do some remote calls

// restore back to the previous runAsSubject
com.ibm.websphere.security.auth.WSSubject.setRunAsSubject(runas_subject);
}
catch (WSSecurityException e)
{
// log error
}
catch (Exception e)
{
// log error
}

You need the following Java 2 Security permissions to run these APIs:

permission javax.security.auth.AuthPermission "wssecurity.getRunAsSubject";
permission javax.security.auth.AuthPermission "wssecurity.getCallerSubject";
permission javax.security.auth.AuthPermission "wssecurity.setRunAsSubject";
