Hello,

thank you for your response.
I tried your test class. I had no error.
But if you add the following lines in you java code :
        javax.xml.bind.Validator v = jc.createValidator();
        v.validate(order);
Then there is the following exception :
DefaultValidationEventHandler: [ERROR]: tag name "TimeLimit" is not
allowed. Possible tag names are:
<com.testfb.datamodel.restriction.TimeLimit>
javax.xml.bind.ValidationException
        at
com.sun.xml.bind.validator.ValidatorImpl.validate(ValidatorImpl.java:118)
        at
com.sun.xml.bind.validator.ValidatorImpl.validate(ValidatorImpl.java:94)
        at com.testfb.Test.main(Test.java:38)

Regards,

Francois Banel

Hi François,

I was unable to unmarshal your xml file without error using Test.java:

     java Test
     LimitType = String

All I can think of is that perhaps you're loading objects generated from
any earlier version of your schema?

Regards,
