Hi

i am invoking a bean(POJO)object in stateless session bean through servlets.but getting ClassCastException in Servlet code. whole activity is as fallows

1)there is a method
WeatherBean getRequestData() in stateless session bean which
returns WeatherBean(serialized bean) object.

2)Then there is a servlet which invokes session bean. and calls
getRequestData() method which returns WeatherBean.
i.e WeatherBean weather=statelessbean.getRequestData();

when i build and execute the code i am getting fallowing exception.

java.lang.ClassCastException: com.common.weather.WeatherBean cannot be cast to com.common.weather.WeatherBean

hi ankith both are correct.

select distinct object(c) from Customer c, Order o where c.custnum=o.custnum.

actually intension of using relationship is to retrieve data from more than one table.a well formed queury always should work whether it is one-one one-many. and EJB-QL is replica of Standard SQL except some oo benifits like traversing..etc.. so above ejb-query will give the expected result.
