WCS Code to find storeId from user LogonId (Expecting that user has registereigd customer role from one store only)

MemberRoleAccessBean m = new MemberRoleAccessBean();

Enumeration mEnum = m.findByMemberIdRoleId(cmdContext.getUserId(),Integer.valueOf("-29"));

Enumeration sEnum = null;

if(mEnum.hasMoreElements()){

   m =(MemberRoleAccessBean)mEnum.nextElement();

   StoreEntityAccessBean stAb = new StoreEntityAccessBean();

   sEnum = stAb.findByMember(Long.valueOf(m.getOrgEntityId()));

   if (sEnum.hasMoreElements()){

   stAb =(StoreEntityAccessBean)sEnum.nextElement();

   storeId = stAb.getStoreEntityId();

}

}
