Hi Parag,
This is very simple. Data is not returned by the entity bean. But you need to extract
data from it.
this is as follows:
1. In your servlet get the reference to session bean
2. In the session bean get the refernce to the entity bean. (If your entity bean
retrives a record then ... Just check your design once again. Entity bean should
represet the record in the database.)
Suppose say, you are accessing a customer record.
3. In the session bean find the customer entity bean using findby methods.
CustomerHome custHome = (Customer) lookup("....");
Customer cust = custHome.findById(1000);
4. Get the data from the entity bean using getMethods invoked on the entity bean
Like,
String str = cust.getName();
int i = cust.getId();
Keep them in a vector and it back to the Servlet.
Hope I am clear.
Regards,
Sripada
