JAX-WS method's Decimal field is NULL when String value is passed

Question

I have Jaxws Soap web service. My "myMethod" method have a decimal type field.

Here is my web service interface:

@WebService(name = "myWs", targetNamespace = "someNamespace")
@Local 
public interface myWsPortType {     
    @WebMethod  
    @RequestWrapper(localName = "myMethod", className = "com.example.MyMethodRequest")  
    public Result myMethod(@WebParam(name = "parameters", mode = Mode.IN) MyMethodParameters parameters); 
}

This is parameter class

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType()
public class MyMethodParameters implements java.io.Serializable {
    @FieldValidation(maxLength = 12)
    @XmlElement(name = "myField", required = false)
    private java.math.BigDecimal myField;
}

Everything works correctly when I pass Correct type of data in myField.

But, the problem is that when I call myMethod and pass String value (instead of Decimal) as parameter no exception is thrown and myField's value is null

Here's Soap Request example

<soapenv:Envelope>
   <soapenv:Header/>
   <soapenv:Body>
      <iss:myMethod>
         <parameters>
            <myField>test</myField>
         </parameters>
      </iss:myMethod>
   </soapenv:Body>
</soapenv:Envelope>

How can I make my ws throw exception when incorrect data type is passed?

It lookls like the XSD Schema is generated just fine, what you are missing is the SchemaValidation annotation to tell JAX-WS to validate the requests and responses with the schema.

Just add @SchemaValidation to your service:

@WebService(name = "myWs", targetNamespace = "someNamespace")
@SchemaValidation
@Local 
public interface myWsPortType { ... }
