JAXB/XJC - XML Schema Parsin Fail

问题

I am currently working with JAXB (and its tool XJC) to "translate" an XML Schema (.xsd) to auto-generated java classes.

I execute the following command :

java -jar "../lib/com.sun.jaxb_1.0.0/jaxb-xjc.jar" schema.xsd

But, obviously, I don't get to compile my schema and get the following errors :

parsing a schema...

Failed to parse a schema.

sorry for the french, but the error can be translated as something like this :

[ERROR] s4s-elt-invalid-content.1 : The content of 'heureType' is not valid. The element 'element' is not valid, is misplaced or appears to many times.

I tried to change the order of my code in multiple ways, but got nothing good.

Here is my code :

</xs:complexType>

        <xs:element name="octet" type="xs:string" minOccurs="0" maxOccurs="unbounded"/> 
    </xs:sequence>
</xs:complexType> 


<!-- *** end *** -->    
</xs:schema> *

does someone know something about this ? :/

回答1:

The error message indicates that your xsd file is not syntactically correct. This is true. If you edit your xsd to fix the problems, the error messages should go away.

When you define a complex type:

<complexType name="foo">
    <sequence>
        <element ... />
        <element ... />
    </sequence>
</complexType>

Make sure that all elements within your complex types are within a sequence element. The <sequence> says that a valid document will contain the contained elements in the specified order.

Of course, there are other options available for defining your complex type. For example, you can use <choice> instead of <sequence>, which means that a valid document will contain one of the contained elements.

It is worthwhile to look at the schema (xsd) for schema files. Check out the link that you have in the top of your schema file (http://www.w3.org/2001/XMLSchema).
