Hibernate custom type to avoid 'Caused by: java.sql.SQLException: Stream has already been closed'

Question

How do I write a custom Long class to handle long values in Oracle, to avoid the following error?

Caused by: java.sql.SQLException: Stream has already bee

Answer 1

I think you get this message when you try to get an Oracle LONG value from the result set multiple times.

I had code like:

        rs.getString(i+1) ;
        if (rs.wasNull()) continue ;

        set(queryAttr[i], rs.getString(i+1)) ;

And I started getting the "Stream has already been closed." error. I stopped getting the error when I changed the code to:

        String str = rs.getString(i+1) ;
        if (rs.wasNull()) continue ;

        set(queryAttr[i], str) ;
