How to use fromXML() without using the ReflectionConverter

[cmathrusse]

I'm attempting to use the fromXML(String, Object) method to update my target object, which happens to be a JPA entity. The issue that I'm having is that XStream uses the ReflectionConverter to assign the new values directly to the fields. This works just fine but EclipseLink, my JPA provider, does not detect the modifications as the setXXX() methods are not invoked. Is there some way that I can ask XStream to use a different converter for this operation so the setXXX() methods will be invoked when assigning the values?

Thanks....

Have you tried the JavaBeanConverter?

Do I need to use the converter directly or is there a way that I can configure XStream to use this Converter when the fromXML() method is invoked?

You have to register it for your types:

xstream.registerConverter(new JavaBeanConverter(xstream.getMapper()) {
    boolean canConvert(Class type) {
        return type == YourClassType.class || (<type is JPA manged bean>);
    }
})
