ORA-31050:Access denied when trying enabling the database-native Web servic

Question

Dear all,
I'm trying to follow the instruction of OBE about "Using Oracle XML DB Web Services for Service-Oriented Architecture " as this url http://st-curriculum.oracle.com/obe/db/11g/r1/prod/datamgmt/xmldb2_b/xmldb2_b.htm#http .
I would like to enable the database-native Web service end point in Oracle XML DB and I already execute the script to create Web Service Endpoint.
Anyway, I got the following error.
ORA-31050: Access denied
ORA-06512: at "XDB.DBMS_XDB", line 528
ORA-06512: at "SYSTEM.ADDSERVLETMAPPING", line 91
I found that this procedure was created on system schema but the problem occur when I tried to call ADDSERVLETMAPPING procedure.
This is a code that I used to enable.

set linesize 132
set long 20000

Test if you can access the generic WSDL using a browser
http://server:port/orawsv?wsdlYou should get prompted for a username and password. If you provide the username and password of a database user who was been granted the Web Services Roles you should see the query service WSDL
