Getting the RunAs subject from the thread


The RunAs subject or invocation subject contains the user authentication information for the RunAs mode set in the application deployment descriptor for this method. we need the Java2 security permissions to run this API: permission javax.security.auth.AuthPermission "wssecurity.getRunAsSubject;".

The RunAs subject (or invocation subject) contains the user authentication information for the RunAs mode set in the application deployment descriptor for this method. This subject is marked read-only when returned from the WSSubject.getRunAsSubject API to prevent replacing existing objects.

Most data within the Subject is not propagated downstream to another server. Only the credential token within the WSCredential credential is propagated downstream and a new Caller subject is generated.

 

  1. Access the WSCredential credential. The WSCredential credential is documented in the API documentation.

  2. Put or set data in the hashmap within the credential.

 

Example

try {
   javax.security.auth.Subject runas_subject;
   com.ibm.websphere.security.cred.WSCredential runas_cred;
 runas_subject = com.ibm.websphere.security.auth.WSSubject.getRunAsSubject();
 if (runas_subject != null)   {
     runas_cred = runas_subject.getPublicCredentials com.ibm.websphere.security.cred.WSCredential.class).iterator().next();
 String RUNASDATA = (String) runas_cred.get ("MYKEY") System.out.println("My data from the RunAs credential is:  " + RUNASDATA );   
} 
}  catch (WSSecurityException e) {
   
// log error 
} catch (Exception e) {
   
// log error 
}
