Message Monitoring issue during XI replacing

Question

Hi XIer,
Due to hardware replacement, so what we are doing is replace QXI( XI testing system) with a new hardware. So we have installed another new XI to replace old QXI.It look ok when we installed new QXI. Because we are using centre SLD to maintain the system info on QXI, so we need to push DXI and PXI info to new SLD on QXI.
the problem comes out when we pushed DXI and QXI info to SLD, we log on to DXI, open RWB->message monitoring->integration engine, then we got following error:
javax.ejb.CreateException: Unable to log on to system SXI in language en with user PIRWBUSER
When I click Message Monitoring again, the error message changes to:
com.sap.aii.utilxi.misc.api.UnexpectedException: Internal Error: An unexpected error occurred (java.lang.NullPointerException: null)
Anyone can give me some suggestions? thank you very much for your effort~

Hi Zhang,
The EJBException exception is thrown by an enterprise Bean instance to its container to report that the invoked business method or callback method could not be completed because of an unexpected error (e.g. the instance failed to open a database connection).
public class RemoveException
extends Exception
The RemoveException exception is thrown at an attempt to remove an EJB object when the enterprise Bean or the container does not allow the EJB object to be removed.

If your interface implementation class is private then
try changing your method declaration from
private to public
