对不起我的英语不好。

我有 EJB：

public class CtrlEJB extends CtrlImplEJB
{

 .....

 public SaleModel doSale(SaleModel sale) throws ValidationException
 {
    log.info("test");
    return new SaleModel();
 }

 .....

}

当我远程调用 doSale 方法时，我在服务器上收到错误：

ERROR [:LogInterceptor:RMI TCP Connection(2)-127.0.0.1] RuntimeException in method: public abstract SaleModel CtrlEJB.doSale(SaleModel) throws ValidationException, java.rmi.RemoteException
java.lang.IllegalArgumentException: wrong number of arguments

    at org.jboss.ejb.plugins.SecurityInterceptor.invoke(SecurityInterceptor.java:111)
    at org.jboss.resource.connectionmanager.CachedConnectionInterceptor.invoke(CachedConnectionInterceptor.java:186)
    ...

此类中的其他方法可以成功运行。请帮忙。感谢您！
