SAP UME from webservice

Hi All,

I want to write  sample java code which will do the following for UME users

a) Create

b)Update

c)Search

d)Delete

I would like to know if there exists any SAP UME webservice which would support the above operations.

I could find the  http://localhost:50200/irj/servlet/prt/soap/UMWebService

But this webservice does not have support for Create and Delete user.

How should i proceed here.

Do i need to create  my own webservice.

Any guideleine would be verfy helpful

I am using SAP Netweaver 7.3

Best Regards

Manoj
