There is a difference in behaviour when @XmlJavaTypeAdapter and @XmlSchemaType are used together at the package and property levels.

PROPERTY LEVEL

package foo;

import java.util.Date;

import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlSchemaType;
import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter;

public class PropertyLevel {

    @XmlJavaTypeAdapter(DateAdapter.class)
    @XmlSchemaType(name="date")
    @XmlElement
    private Date date;

}

PACKAGE LEVEL

package foo;

import java.util.Date;

import javax.xml.bind.annotation.XmlElement;

public class PackageLevel {

    @XmlElement
    private Date date;

}

@XmlJavaTypeAdapters(
    @XmlJavaTypeAdapter(value=DateAdapter.class, type=Date.class)
)
@XmlSchemaTypes({
    @XmlSchemaType(name="date", type=Date.class)
})
package foo;

import javax.xml.bind.annotation.adapters.*;
import javax.xml.bind.annotation.*;
import java.util.Date;

GENERATED SCHEMA

Note how the type of the date elements is different.
