verification of schema document

[David Bloom <ya...@gmail.com>]

I have used JaxMe to unmarshall (schema doc to java classes).

The code is generated and compiles fine but it is not doing what I expected.
I want some kind of error kicked out if the 
user does not supply (see below) correct number of chars for machine
type in the xml file. .

JaxME gives it a type of String :

                                 public java.lang.String getMachineType();
  
                                 public void
setMachineType(java.lang.String pMachineType);

I have considered binding in a verify function like:
                                 unmarshaller.setValidating(true);

		Validator v = context.createValidator();
		MyHandler veh = new MyHandler();
		v.setEventHandler(veh);


But, I thought that Jaxme would do this verification as built in since
the schema specifies a format of exactly 4 digit characters.

When I apply the xml to schema document, my IDE recognizes an error
when I place more than the specified number of digits. I was expecting
the same behavior
out of this jaxb implementation. Am I missing something? 


Thanks in advance,
David



Below is a snippet of a schema doc:

<complexType name="sat_incidents">
        <sequence>
            <element name="sat_incident" minOccurs="0" maxOccurs="unbounded">
                <complexType>
                    <sequence>
                        <element name="productName" type="string"/>
                        <element name="score" type="decimal"/>
                             
                    </sequence>
                    <attribute name="machineType" type="sat:mtype"
use="required"/>
                    <attribute name="timestamp"   type="sat:ts_format"
use="required"/>
                </complexType>
            </element>
        </sequence>
    </complexType>

..

<simpleType name="ts_format">
        <restriction base="string">
            <pattern value="\d{4}-\d{2}-\d{2}\s\d{2}:\d{2}"/>
        </restriction>
    </simpleType>
    
        
    
    <simpleType name="mtype">
        <restriction base="string">
                <pattern value="\d{4}" />
        </restriction>
    </simpleType>

You are right, that such validation is not yet implemented. In fact, you 
are the first one who asked for it. (About time! :-)

To add such a validation, have a look into the class AtomicTypeSGImpl, 
method getCastFromString(String): This is the method generating the code 
that unmarshals a string into the actual data type. This method could be 
prefixed with code looking like this:

     Facet patternFacet = pController.getFacet(Facet.PATTERN);
     if (patternFacet != null) {
         // Add code, that compares pValue against a regular expression
         // compiled from patternFacet.getValues().
	// Note: There may be multiple patterns to apply, do not use
	// patternFacet.getValue()!
	...
     }

Patches are very welcome.

Jochen
