Http invoker求高人指点

Http Invoker是否能返回对象？
代码如下PrintApplay.java（服务端与客户端的都一样）public class PrintApply implements Serializable {
private static final long serialVersionUID = 1L;
private String yybs;
private String sjbbs;
private String fqbs;        public String getYybs() {
return yybs;
}
public void setYybs(String yybs) {
this.yybs = yybs;
}
public String getSjbbs() {
return sjbbs;
}
public void setSjbbs(String sjbbs) {
this.sjbbs = sjbbs;
}
public String getFqbs() {
return fqbs;
}
public void setFqbs(String fqbs) {
this.fqbs = fqbs;
}服务端interfaceimport com.hxsmart.sicard.si.model.PrintApply;public interface RemoteService {

public PrintApply receivePrintApply(String name,String idcd,String bankId,String nodeName,String nodeId);}服务端实现类public class RemoteServiceImpl implements RemoteService {
         private ClientService clientService;
         @Override
         public PrintApply receivePrintApply(String name, String idcd, String bankId,
String nodeName, String nodeId) {
                StringBuffer sb = new StringBuffer();
                sb.append(name).append(idcd).append(bankid).append(nodeName).append(nodeId);
                List<PrintApply> list = clientService.sentMsg(sb.toString());
PrintApply printApply = list.get(0);
return printApply;
         }
}客户端调用服务端接口public class RemoteExchgsvrServerImpl implements RemoteExchgsvrServer { @Override
public List PrintInfoApply(String idcd, String name, String bankId,
String nodeId, String nodeName) {
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("remote.xml");

try {
RequestService service = (RequestService) applicationContext.getBean("remoteService");
PrintApply printApply = service.receivePrintApply(name, idcd, bankId, nodeName, nodeId);
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
}报错代码：PrintApply printApply = service.receivePrintApply(name, idcd, bankId, nodeName, nodeId);客户端报错信息：

客户端是没有任何地方声明或使用com.hxsmart.sicard.si.model.PrintApply这个的，确定没有，可是为什么提示找不到这个呢？求解！
