I found how to solve this problem without using JDBC's setString() method which limits the data to 4K.

What you need to do is to use preparedStatement.setClob(int parameterIndex, Reader reader). At least this is what that worked for me. Thought Oracle drivers converts data to character stream to insert, seems like not. Or something specific causing an error.

Using a characterStream seems to work for me. I am reading tables from one db and writing to another one using jdbc. And i was getting table not found error just like it is mentioned above. So this is how i solved the problem:

case Types.CLOB:   //Using a switch statement for all columns, this is for CLOB columns
        Clob clobData = resultSet.getClob(columnIndex); // The source db
        if (clobData != null) {
            preparedStatement.setClob(columnIndex, clobData.getCharacterStream());
        } else {
            preparedStatement.setClob(columnIndex, clobData);
        }
        clobData = null;
        return;

All good now.
