            // write characters to writer.

            System.out.println("str = " + str);
            /*
             * Returns: StringBuffer holding the current
             * buffer value.
             */
            StringBuffer sb = stringWriter.getBuffer();
            System.out.println("sb = " + sb);

        }
        finally
        {
            if (stringWriter != null)
            {
                stringWriter.close();
            }
        }
