Question

I need to convert my object generated from WSDL file with CXF cxf-codegen-plugin to JSON string. I am not lucky to find any solution to that.

As far as I’ve got is: I’ve created a Spring config of CXF JSONProvider:

<bean id="jsonProvider" class="org.apache.cxf.jaxrs.provider.json.JSONProvider">
    <property name="dropRootElement" value="true"/>
    <property name="dropCollectionWrapperElement" value="false"/>
    <property name="serializeAsArray" value="true"/>
    <property name="ignoreNamespaces" value="true"/>
</bean>

injected it into my bean and now I am trying to use:

try {
    StringWriter writer = new StringWriter();

    jsonProvider.writeTo(
            evaluationType,
            EvaluationType.class,
            new Annotation[]{},
            MediaType.APPLICATION_JSON_TYPE,
            null,
            new StringOutputStream(writer));

    return writer.toString();
} catch (IOException e) {
    LOGGER.error("e", e);
    return "";
}

The question is, what kind of annotations I have to provide to this method? There is no documentation about it. I am getting:

Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
com.company.test.evaluation.evaluation.EvaluationImpl$1 is a non-static inner class, and JAXB can't handle those.
    this problem is related to the following location:
        at com.company.test.evaluation.EvaluationImpl$1

This EvaluationImpl is the class in which I am calling this method. Please advice what kind of annotations I’ve to provide to this method. Or maybe there is other ways of doing this using CXF JSONProvider?

I would suggest you to use Jackson ObjectMapper to convert your java objects to JSON there a lot of options for configuring Jackson ObjectMapper and it is more easier to use.
