Why does jaxb log "No XmlSchema annotation found for <my package name>" when getting an instance of JAXBContext?

I have an xsd file that, when compiled using the jaxb-2 maven plugin, generates java source. The header for my xsd is:

<schema targetNamespace="example.company.com"
elementFormDefault="qualified" xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:prefix="example.company.com">

Whenever I attempt to get the JAXBContext for use in marshaling/unmarshaling using this code:

JAXBContext jc = JAXBContext.newInstance("com.company.example", com.company.example.ObjectFactory.class.getClassLoader());

I get hundreds of error messages in my console that look like this:

No XmlSchema annotation found for com.company.example

After all of those error messages, the marshaling works. I would like to get rid of the errors though.

The jaxb2 maven plugin is defined in my pom like so:

<plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>jaxb2-maven-plugin</artifactId>
        <version>1.3.1</version>
        <dependencies>
            <dependency>
                <groupId>com.sun.xml.bind</groupId>
                <artifactId>jaxb-xjc</artifactId>
                <version>2.1.13</version>
            </dependency>
            <dependency>
                <groupId>net.sourceforge.ccxjc</groupId>
                <artifactId>cc-xjc-plugin</artifactId>
                <version>2.0</version>
            </dependency>
        </dependencies>
        <executions>
            <execution>
                <phase>generate-sources</phase>
                <goals>
                    <goal>xjc</goal>
                </goals>
            </execution>
        </executions>
        <configuration>

            <arguments>-enableIntrospection -verbose</arguments>
            <schemaDirectory>${basedir}/src/main/xsd</schemaDirectory>
            <outputDirectory>${basedir}/src/main/java</outputDirectory>
            <packageName>com.company.example</packageName>
            <verbose>true</verbose>
            <failOnNoSchemas>true</failOnNoSchemas>
            <clearOutputDir>false</clearOutputDir>
            <arguments>-copy-constructor</arguments>
            <extension>true</extension>
        </configuration>
    </plugin>

It looks as though the package-info.java (that contains the @XmlSchema annotation) file that was generated along with the other model files from the XML Schema is not being compiled.

Update

I am running OSGi and using Java SE

You should make sure you import the javax.xml.bind package in your manifest. Their can be ClassLoader issues with javax classes in OSGi environments.

You didn't map your package to the namespace "http://www.w3.org/2001/XMLSchema". To do this, make your header like this:

<schema
  xmlns=...
  xmlns:po=....
  targetNamespace="http://www.w3.org/2001/XMLSchema"
>

Also, add this annotation to your class:

@javax.xml.bind.annotation.XmlSchema (namespace = "http://www.w3.org/2001/XMLSchema")

For more information about XmlSchema, see these docs: http://docs.oracle.com/javase/7/docs/api/javax/xml/bind/annotation/XmlSchema.html
