JIBX: Classes generated from maven codegen plugin

I use Jibx CodeGen maven Plugin to generate java sources and binding from xsd files. I want to maintain several versions of the xsd in the same applications so I plan to generate to a different target package depending the version of the XSD.

JBix seems to generate java package based on the namespaces of the xsd files.

ie. for namespace http://www.example.jibx.org/generated/v30/types it generates package org.jibx.example.generated.v30.types

During maven build code generation seems to work and binding files are generated but during the binding phase, it says that Verification was a failure :

I wrote A Junit test to make sure that jibx can instanciate the factory for my binded objects and unmarshall xml file against it.

Junit unit test : FooTest.java

@Test
public void testFoo1()
{  
    IBindingFactory foo30Factory = null;
    try
    {
        foo30Factory = BindingDirectory.getFactory("binding_v30", Foo.class);
    }
    catch (JiBXException e)
    {
        String l_msg = "Cannot create factory ";
        LOGGER.error(l_msg, e);
        Assert.fail(l_msg + e.getMessage());
    }

    IUnmarshallingContext unmarshmallingContext = null;
    try
    {
        unmarshmallingContext = foo30Factory.createUnmarshallingContext();
    }
    catch (JiBXException e)
    {
        String l_msg = "Cannot create unmarshmalling context ";
        LOGGER.error(l_msg, e);
        Assert.fail(l_msg + e.getMessage());
    }

    String l_xmlFileToTest = "/xml/foo1.xml";
    LOGGER.info("Loading file : " + l_xmlFileToTest);
    InputStream in = this.getClass().getResourceAsStream(l_xmlFileToTest);
    BufferedReader buffer = new BufferedReader(new InputStreamReader(in));
    Foo l_fooObtained = null;
    try
    {
        l_fooObtained = (Foo) unmarshmallingContext.unmarshalDocument(buffer);
    }
    catch (JiBXException e)
    {
        String l_msg = "Cannot instanciate object for class " + Foo.class;
        LOGGER.error(l_msg, e);
        Assert.fail(l_msg + e.getMessage());
    }

    Assert.assertNotNull("l_coeaObtenu ne doit pas etre null", l_fooObtained);
    }

foo1.xml

<?xml version="1.0" encoding="UTF-8" ?>
    <foo>

I got this stacktrace when I run it: No unmarshaller for element "generic"

回答1:

Marc,

Take a look at the example in the JiBX schema library for the

Opentravel schema Library

It is very similar to your problem Many schemas with the same namespace need to be bound to different java packages.

Also, I would suggest that you use a newer version of JiBX, such as 1.2.6

Cheers!

Don

I finally found the answer. I was missing namepace declaration in the xml I wanted to consume. It works with a correctly shaped one as the following one :

    <?xml version="1.0" encoding="UTF-8" ?>
        <foo:foo xmlns:foo="http://www.example.jibx.org/generated/v30/foo"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://www.example.jibx.org/generated/v30/foo foo-3.0.xsd">
            <generic>
                <type>12345</type>
                <isValid>1</isValid>
            </generic>
            <specific>
                <label>Label example</label>
                <dateFoo>01/01/2015</dateFoo>
            </specific>
        </foo:foo>
