Rick Hillegas commented on DERBY-1059:
--------------------------------------

Thanks, Anurag, this looks like an improvement. However, lots of useful javadoc 
has disappeared. Could you add appropriate javadoc to all of the methods in all 
of these classes?

> org.apache.derby.impl.jdbc.EmbeddedCallableStatement40 and 
> org.apache.derby.client.am.CallableStatement40 are instantiating 
> Preparewdstament in 
> constructor. Becasue of this call to stored procedure with out param fails.
> Instantiatiation of prepared was done to share the common method in prepared 
> statement and callbale statement. But this aporach causes another issue of 
> creating two instance of statement (one by calling super () and another by 
> instantiating prepared statement). 
> I can think of two solution of this problem 
> 1. Create another class which handles the common methods in 
> PrepardStatement40 and CallableStatement40 classes.
> 2. Duplicate the common method in both classes. 
> I feel 1st one is better. It will will be easier to fix any issue in the 
> common methods and chance to miss to fix in one of the classes will be 
> eliminated.
