RE: data validation

[Greg Michalopoulos]

The server's WSDL should specify if a parameter can be null or not.  One way to do that is the minOccurs and maxOccurs properties of an element.    <element maxOccurs="1" minOccurs="1" name="TransactionID" type="xsd:int" />   This just ensures that the element is specified in the request but does not care if it is null.  To do that use the nillable property.   <element nillable="false" maxOccurs="1" minOccurs="1" name="TransactionID" type="xsd:int" />   If you just want to do this checking on the client side, then that has to be specified in the client side code as you would normally do in Java.

Basically the data the client sends should not be null. When it comes to my web service all the required parameters should not be null. E.g. if the client is supposed to send a struct that identifies a client e.g. first name, last name, address1, address2, city,state,zip1,zip2. All the members of the struct can’t be null except for address2 & zip2. Is there a way to do this?   Thanks in advance.   Vince.
