Answer 1

From your XML file, you can define the XML schema (see following example) and let generate the Java binding from it.
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:element name="activity">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="code" type="xsd:string" />
<xsd:element name="description" type="xsd:string" />
<xsd:element name="deals">
<xsd:complexType>
<xsd:sequence maxOccurs="unbounded">
<xsd:element name="deal">
<xsd:complexType>
<xsd:simpleContent>
<xsd:extension base="xsd:string">
<xsd:attribute name="key" type="xsd:string" />
</xsd:extension>
</xsd:simpleContent>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>

Answer 2

#XmlRootElement(name = "activity")
#XmlAccessorType(XmlAccessType.FIELD)
public class Activity {
#XmlElement
private String code;
#XmlElement
private String description ;
#XmlElementWrapper
#XmlElement(name="detail")
public List<Detail> details = new ArrayList<Detail>();
public Activity() {}
and have a Detail class as follows
#XmlRootElement(name = "detail")
#XmlAccessorType(XmlAccessType.FIELD)
public class Detail {
#XmlAttribute
private String key;
#XmlValue
private String value;
