web service navigator not working

hello,

I am trying to test standard SAP web service.

employeemasterdatareplicationr_OUT

1. I tried it from SOAPUI tool with the WSDL file,

SRT: Plain SOAP: Reliable messaging (RM) configured, but no Message ID and no WSRM assertion provided.

2. I tried test  from SOAMANAGER then I am getting following error -- (button "open web service navigator for selected binding")

http://host:8001/sap/bc/srt/wsdl/flv_10002A1111D1/bndg_url/sap/bc/srt/scs/sap/employeemasterdatareplicationr?sapclient=100/ws/simple/getEmployeeMasterDataReplicationConfirmation_Out

then it routing to wsnavigator and getting 404 error.

3. WS Navigator is not working from SAP.

http://hostname:50000/wsnavigator  - this is also not working 404 error.

Can you please let me know how tot resolve these errors?

Regards,

Khaja.
