问题:
I made some classes using xjc.
public class MyType { @XmlElementRefs({ @XmlElementRef(name = "MyInnerType", type = JAXBElement.class, required = false), }) @XmlMixed protected List<Serializable> content; public List<Serializable> getContent() { if (content == null) { content = new ArrayList<Serializable>(); } return this.content; } }
But i cant add inner elements using
getContent().add(newItem);
because MyInnerType is not Serializable. Why its not a List of Objects? How do i add inner elements?

Please take a look here and here (one should for sure address your scenario).
From 2nd link:
<!-- schema fragment having mixed content --> <xs:complexType name="letterBody" mixed="true"> <xs:sequence> <xs:element name="name" type="xs:string"/> <xs:element name="quantity" type="xs:positiveInteger"/> <xs:element name="productName" type="xs:string"/> <!-- etc. --> </xs:sequence> </xs:complexType> <xs:element name="letterBody" type="letterBody"/> // Schema-derived Java code: // (Only annotations relevant to mixed content are shown below, // others are ommitted.) import java.math.BigInteger; public class ObjectFactory { // element instance factories JAXBElement<LetterBody> createLetterBody(LetterBody value); JAXBElement<String> createLetterBodyName(String value); JAXBElement<BigInteger> createLetterBodyQuantity(BigInteger value); JAXBElement<String> createLetterBodyProductName(String value); // type instance factory LetterBody> createLetterBody(); } public class LetterBody { // Mixed content can contain instances of Element classes // Name, Quantity and ProductName. Text data is represented as // java.util.String for text. @XmlMixed @XmlElementRefs({ @XmlElementRef(name="productName", type=JAXBElement.class), @XmlElementRef(name="quantity", type=JAXBElement.class), @XmlElementRef(name="name", type=JAXBElement.class)}) List getContent(){...} }

What do you think you should be adding in there? I have used similar generation and had fields like this and the expectation was that it would be String content.
It'd probably help to show the xsd this was generated from.
