I got this XML structure:

<Tax>
  <Money currency="USD">0.00</Money>
  <Description xml:lang="en">
     17.5% Non-Recoverable
    <ShortName>vatspecial</ShortName>
  </Description>
</Tax>

Notice that Description node has MixedContent (composed with text and XML) and this is the XSD part regarding Description node:

<xsd:complexType name="TaxDescriptionType">
  <xsd:sequence>
    <xsd:element name="ShortName" type="xsd:string" />
  </xsd:sequence>
  <xsd:attribute ref="xml:lang" />
</xsd:complexType>

Everything is ok at this point, XJC outputs the generated classes like this one regarding TaxDescriptionType:

package org.com.project;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlSchemaType;
import javax.xml.bind.annotation.XmlType;
import javax.xml.bind.annotation.adapters.CollapsedStringAdapter;
import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "TaxDescriptionType", propOrder = {
    "shortName"
})
public class TaxDescriptionType {

    @XmlElement(name = "ShortName", required = true)
    protected String shortName;
    @XmlAttribute(name = "lang", namespace = "http://www.w3.org/XML/1998/namespace")
    @XmlJavaTypeAdapter(CollapsedStringAdapter.class)
    @XmlSchemaType(name = "NCName")
    protected String lang;

    /**

     * 
     * @return
     *     possible object is

     *     
     */
    public String getShortName() {
        return shortName;
    }

    /**
     * Sets the value of the shortName property.
     * 
     * @param value
     *     allowed object is
     *     {@link String }
     *     
     */
    public void setShortName(String value) {
        this.shortName = value;
    }

    /**
     * Gets the value of the lang property.
     * 
     * @return
     *     possible object is
     *     {@link String }
     *     
     */
    public String getLang() {
        return lang;
    }

    /**
     * Sets the value of the lang property.
     * 
     * @param value
     *     allowed object is
     *     {@link String }
     *     
     */
    public void setLang(String value) {
        this.lang = value;
    }

}

Then, with the above class I am able to work around with the elements like this:

taxDescriptionType.setLang("en");
taxDescriptionType.setShortName("vatspecial");
/* missing value: 17.5% Non-Recoverable */

But the problem is that I can't found a way to get or set the 17.5% Non-Recoverable text of the MixedContent-ComplexType from the above XML example.

This is what I tried and it's not working:

Used mixed="true" attribute like this:

<xsd:complexType name="TaxDescriptionType" mixed="true">

(I think XJC is ignoring the last attribute)

Doing some research, I found this:

JAXB XJC-компилятор, игнорирующий mixed = true в документах схемы XML

Но я не уверен, что это способ решить эту проблему. В одном из ответов сказано, что это ошибка, а в другом показан код, который преобразуетMixedContent вList<Serializable> и, возможно, следующая ситуация будет о том, как справиться с этим:

taxDescriptionType.getContent().add(Serializable element);

(And I really don't know how to deal with a Serializable element)
