xml이 채워지지 않습니다. - JAXB를 사용합니다.

Question

안녕하세요. 학교 실험실에서 문제가 좀 있습니다. 본질적으로 XML 스키마를 작성하고 JAXB 컴파일러를 실행 한 다음 Java 클래스를 작성하여 직원 레코드를 직렬화해야했습니다. "employeeSchema.xsd"

<?xml version="1.0" encoding="UTF-8"?> 
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" 
     xmlns:jxb="http://java.sun.com/xml/ns/jaxb" 
     jxb:version="2.0"> 

<xs:element name="employee" type="employeeType"/> 

<xs:complexType name="jobListType"> 
    <xs:sequence> 
     <xs:element name="job_id" type="xs:positiveInteger"/> 
     <xs:element name="job_title" type="xs:string"/> 
     <xs:element name="min_salary" type="xs:positiveInteger"/> 
     <xs:element name="max_salary" type="xs:positiveInteger"/> 
    </xs:sequence> 
</xs:complexType> 

<xs:complexType name="departmentType"> 
    <xs:sequence> 
     <xs:element name="department_id" type="xs:positiveInteger"/> 
     <xs:element name="department_name" type="xs:string"/> 
     <xs:element name="manager_id" type="xs:positiveInteger"/> 
     <xs:element name="location_id" type="xs:positiveInteger"/> 
    </xs:sequence> 
</xs:complexType> 

<xs:complexType name="employeeType"> 
    <xs:sequence> 
     <xs:element name="employee_id" type="xs:positiveInteger"/> 
     <xs:element name="first_name" type="xs:string"/> 
     <xs:element name="last_name" type="xs:string"/> 
     <xs:element name="email" type="xs:string"/> 
     <xs:element name="phone_number" type="xs:string"/> 
     <xs:element name="hire_date" type="xs:date"/> 
     <xs:element name="job" type="jobListType"/> 
     <xs:element name="salary" type="xs:positiveInteger"/>  
     <xs:element name="commission_pct" type="xs:decimal"/> 
     <xs:element name="manager_id" type="xs:positiveInteger"/> 
     <xs:element name="department" type="departmentType"/>    
    </xs:sequence> 
</xs:complexType> 

</xs:schema> 

라는 파일 그리고 나는 그것이 JAXB를 사용하여 준수하면, 나는 "employee.java"

    } catch(JAXBException jbe){

     hireDate=df.parse("20/02/2014"); 
    } 

    catch (Exception e){ 
    } 


    String phoneNumber = "647-588-3774"; 

    JobListType jList = new JobListType(); 

    int theJobId = 12345; 
    BigInteger jID = BigInteger.valueOf(theJobId); 
    jList.setJobId(jID); 

    jList.setJobTitle("Java Developer"); 

    int theMinSal = 50000; 
    BigInteger jMinSal = BigInteger.valueOf(theMinSal); 
    jList.setMinSalary(jMinSal); 

    int theMaxSal = 150000; 
    BigInteger jMaxSal = BigInteger.valueOf(theMaxSal); 
    jList.setMinSalary(jMaxSal); 

    int theSalary = 90000; 
    BigInteger salary = BigInteger.valueOf(theSalary); 

    BigDecimal commPct = new BigDecimal(5.0); 

    int theManagerID = 12345; 
    BigInteger managerID = BigInteger.valueOf(theManagerID); 

//DepartmentType departmentID 
    //setDepartmentID 

    employee myEmp = new employee(); 

    myEmp.make(empID, firstName, lastName, email, phoneNumber, hireDate, jList, salary, commPct, managerID); 

    myEmp.marshal(); 
} 
} 

이라는 클래스를 생성 : 그래서 여기

는 내가 지금까지 무엇을 가지고 나는 employee.java을 실행할 때

는하지만, 내 출력은 다음과 같습니다 :

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><employee/> 

을하지만 목적은 표시하는 것입니다 내가 본부에서 정의한 직원. 모든 종류의 조언이나 도움이 크게 감사하겠습니다.

대단히 감사합니다.

건배
