Field Detail

sessionId

public static final java.lang.ThreadLocal sessionId

Use this for setting session id per current thread. HttpServletController uses this, for example, to set the session id in this variable for each request. As a result the Handler may call this variable to get the sessionId to pass to the ConnectionManager.

 Usage (for setting):
 CLEUtil.sessionId.set(value);

 Usage (for getting):
  Object value = CLEUtil.sessionId.get();
