我正在用Eclipse IDE用Java生成一个web服务，该服务有一个类，其中包含通过Hibernate映射的DAO查询数据库的方法。如果我在不使用所有Hibernate类型（作为传递给方法的参数或返回类型）的情况下创建web服务，它会成功；如果我试图使用所有Hibernatebean来映射它们，它会失败。以前有人遇到过这个问题吗？
问题是我没有将所有Hibernate对象映射到web服务中。当然没有，当我需要由使用该服务的客户使用它们时，它们的使用量不足。
有人面临这个问题吗？
谢谢，我很感激任何帮助。。。
在我的例子中，下面类的第一个方法"mapVM"返回一组"VmStatistics"，导致如下错误：
An internal error occurred during: "Generating JAX-WS Web Services".
Unable to create JAXBContext
而如果我将方法从Hibernate对象中删除，则在创建ws时不会映射"VmStatistics"。其他对象也是如此，所以我在ws-中缺少bean
hibernate逻辑在一个jar文件中，包含6个bean。
这是我为生成WS的类（包含5个方法）
public class DBHelper {
public DBHelper(){}
public static Set<VmStatistics> mapVM(Vm vm){
Set< VmStatistics> s = vm.getVmStatisticses();
return s;
}
/**
* Loads all companies
*
* @return A list of company objects
*/
public static ArrayList<Company> getCompanyList(){
ArrayList<Company> lCompanies = new ArrayList<Company>();
...
return lCompanies;
}
/**
* Loads all the available countries
*
* @return
* Returns a list of string objects
*/
public static ArrayList<String> getCountryList(){
ArrayList<String> lCountires = new ArrayList<String>();
...
return lCountires;
}
/**
* Loads the companies of the given country name
*
* @param pCountry a given country name
*
* @return A list of company objects
*/
public static ArrayList<Company> getCompanyListByCountry(String pCountry){
ArrayList<Company> lCompanies = new ArrayList<Company>();
...
return lCompanies;
}
/**
* Loads the latest reading performed in the datacenter
*
* @param pCountry
* A given country name
*
* @param pCompany
* A given company object
*
* @return The list of server objects which contains the associated VMs and the relative statistics
*/
public static Collection<Server> getCurrentReading(String pCountry, Company pCompany){
...
return lServer;
}
}
现在，我尝试在ws的模式文件和wsdl中手动添加bean，它接受了它，但在tomcat部署阶段，它给出了相同的错误，但由于这是一个日志错误，而不是eclipse，我认为更清楚地理解：
我试图通过修改sdl和模式文件并添加未映射的类型来手动生成。。。在tomcat face上的部署中，它给出了相同的错误。。。也许这会更清楚，因为这是一个日志错误：

谢谢你，
通过添加@XmlJavaTypeAdapter( TimestampAdapter.class) BUT，通过创建TimestampAdapter类使其返回java.util.Date而不是java.sql.Date 来解决问题
