Jaxb unmarshal null

Minimal, Complete, and Verifiable. Note Your question is partly based on a misunderstanding. Andreas Andreas k 9 9 gold badges silver badges bronze badges. Thank you very much. It seems that I didn't understand that when writing the class to be use for reading and writing that they can't have anything additional in them?

Thanks again. Your Swing code needs a way of setting the value, and the Marshaller needs a way of setting the value, so providing a method for each is appropriate. Now, you might consider putting the Swing code where your other Swing code is, and keep class Save a "clean" XML class.

In that case, your Swing code would also use the setPartsList String[] method. Just for completeness' sake: The unmarshaller does not return null it cannot , it returns a non-null instance of Save. However, the field inside is null. I submitted an edit to clarify. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password. Post as a guest Name.

Stack Overflow works best with JavaScript enabled. Throws: IllegalArgumentException - if the adapter parameter is null. This method allows applications to use a configured instance of XmlAdapter. When an instance of an adapter is not given, an unmarshaller will create one by invoking its default constructor.

Parameters: type - The type of the adapter. The specified instance will be used when XmlJavaTypeAdapter. If null, it will un-register the current adapter set for this type. Throws: IllegalArgumentException - if the type parameter is null. This is the reverse operation of the setAdapter javax. XmlAdapter method. Unmarshal time validation, enabled via setSchema Schema , must be supported even when unmarshaller is performing XOP processing.

Register unmarshal event callback Unmarshaller. There is only one Listener per Unmarshaller. Setting a Listener replaces the previous set Listener. One can unregister current Listener by setting listener to null. Returns: registered Unmarshaller. Listener or null if no Listener is registered with this Unmarshaller.

Return Unmarshaller. Get the particular property in the underlying implementation of Unmarshaller. Get the JAXP 1. Get an unmarshaller handler object that can be used as a component in an XML pipeline. Associates a configured instance of XmlAdapter with this unmarshaller. Associate a context that resolves cid's, content-id URIs, to binary data passed as attachments.

Set the particular property in the underlying implementation of Unmarshaller. Specify the JAXP 1. Unmarshal XML data from the specified file and return the resulting content tree. Unmarshal XML data from the specified Reader and return the resulting content tree.

Unmarshal XML data from the specified pull parser and return the resulting content tree. Implements Unmarshal by Declared Type. Specifies whether or not the default validation mechanism of the Unmarshaller should validate during unmarshal operations. Indicates whether or not the Unmarshaller is configured to validate during unmarshal operations.

Allow an application to register a ValidationEventHandler. Gets the adapter associated with the specified type. I am using JAXB to convert XML file to java object I have looked a lot in the examples on the web but still get null values in my object when I unmarshall it to a java object what I miss?

Refer this, howtodoinjava. Btw your xml structure is wrong you cannot have more than one root element. Evgeniy Dorofeev Evgeniy Dorofeev k 27 27 gold badges silver badges bronze badges.
