Hi Leslie,
The problem is a namespace conflict.
In the root process element you have defined xmlns:ns="
http://ws.wso2.org/dataservice";. But in the variable it's xmlns:ns="
http://ws.apache.org/axis2";.
So when your xpath query for *ns:nombre* , it returns selection failure as
prefix in the following assigned variable has a different namespace.
<ns:insertarSolicitud xmlns:ns="http://ws.apache.org/axis2"; xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance";>
<ns:nombre></ns:nombre>
<ns:servicio></ns:servicio>
