MyEclipse创建SOAP Web Services提示Unable to Create JAXBContext错误

雷雷518 2013-06-14 10:03:22

MyEclipse完成一个订单管理的SOAP Web Service，在生成wsdl时提示Unable to Create JAXBContext错误。具体：我建了类PurchaseOrder来表示从数据库读出的订单信息，并建立PurchaseOrderDatabase类，内含读取MySQL中数据库订单的方法和属性PurchaseOrder po，用读取的数据库信息来初始化po。然后建立服务类PurchaseOrderSOAP，希望返回PurchaseOrderDatabase中po的toString给客户端，但自动生成wsdl时提示错误，未成功生成wsdl文档。
//PurchaseOrderSOAP类的代码如下：
public class PurchaseOrderSOAP {
//soap web service
public String queryByCustomerName(String CustomerName) throws ClassNotFoundException {
//PurchaseOrderDtatbase为访问数据库的类，包含PurchaseOrder(订单信息类)属性，
//从数据库读出数据后，初始化属性po
PurchaseOrderDatabase podb = new PurchaseOrderDatabase();
//访问数据库，并初始化podb属性PurchaseOrder po
podb.getDataByCustomerName(CustomerName);

//返回订单信息po的字符串
return CustomerName+"的订单信息："+podb.getPO().toString();
}
}

//PurchaseOrderDatabase类的代码如下：
public class PurchaseOrderDatabase {
//responsible for connecting with the database and getting the specific data for PurchaseOrder
private PurchaseOrder po;

//default constructor
public PurchaseOrderDatabase() {
po = new PurchaseOrder();
}

//getters
public PurchaseOrder getPO() {
return po;
}
//get data by customer name from the database
public void getDataByCustomerName(String CustomerName) throws ClassNotFoundException{
java.sql.Connection conn;
java.lang.String strConn;
java.sql.PreparedStatement preparedStmt;//database statement object
java.sql.ResultSet sqlRst;//result set

try{
try{
Class.forName("com.mysql.jdbc.Driver").newInstance();
}catch(InstantiationException ex){
Logger.getLogger(PurchaseOrderDatabase.class.getName()).log(Level.SEVERE, null, ex);
}catch(IllegalAccessException ex){
Logger.getLogger(PurchaseOrderDatabase.class.getName()).log(Level.SEVERE, null, ex);
}
conn = java.sql.DriverManager.getConnection("jdbc:mysql://localhost/order", "root", "0000");
preparedStmt = conn.prepareStatement("select * from purchaseorder");//get all data of the form
sqlRst = preparedStmt.executeQuery();
//System.out.println(sqlRst.toString());

//select item which customername equals to CustomerName from sqlRst
while(sqlRst.next()){
if(sqlRst.getString("customername").equals(CustomerName)){
po.setIDPurchaseOrder(sqlRst.getString("idpurchaseorder"));
po.setCustomerName(sqlRst.getString("customername"));
po.setCustomerAddress(sqlRst.getString("customeraddress"));
po.setOrderInfo(sqlRst.getString("orderinfo"));
po.setProductPrice(Float.parseFloat(sqlRst.getString("productprice")));
po.setDelivery(Float.parseFloat(sqlRst.getString("delivery")));
po.setTotal(Float.parseFloat(sqlRst.getString("total")));
po.setTime(sqlRst.getString("time"));
}
}

//close
sqlRst.close();
preparedStmt.close();
conn.close();
}catch(java.sql.SQLException e){
System.out.println(e.toString());
}
}
}
