Hi May,
If I understand you correctly you want to get the identity of the caller, which
can be obtained using the EJBContext as follows:
public class MyBean implements EntityBean {
public int something;
public double somethingelse;
public long timestamp;
public String callerID;
public EntityContext ejbContext;
public void setEntityContext(EntityContext cntxt){
ejbContext = cntxt;
}
public void ejbStore( ){
Principal principal = ejbContext.getCallerPrincipal();
callerID = principal.getName();
timestamp = System.currentTimeMillis();
...
}
...
}
Of course, the Principal is not necessarily the same as the person running the
application. It all depends on how you set up your security environment, but if
you know your target environment and how Principal maps to authenticated users,
then this should work fine.
