Description

Buffer component doesn't support any special characters such as national characters. HtmlBufferResponseWriterWrapper causes this problem. Buffer temporary writer opened doesn't define character encoding at all.

Solution: rewrite HtmlBufferResponseWriterWrapper like this:

public class HtmlBufferResponseWriterWrapper extends HtmlResponseWriterImpl
{
/** string writer to use to write content */
private StringWriter stringWriter;
/** print writer to wrap string writer */
private PrintWriter writer;
/** original response writer*/
private ResponseWriter initialWriter;

/**

• Returns original faces response writer instance.
• @return
  */
  public ResponseWriter getInitialWriter() { return initialWriter; }

/**

• Creates instance of HtmlBufferResponseWriterWrapper.
  *
• @param initialWriter initial faces response writer instance
• @return
  */
  public static HtmlBufferResponseWriterWrapper getInstance(ResponseWriter initialWriter) { StringWriter stringWriter = new StringWriter(); PrintWriter instanceWriter = new PrintWriter(stringWriter, true); return new HtmlBufferResponseWriterWrapper(initialWriter, stringWriter, instanceWriter); }

/**

• Constructor.
  *
• @param initialWriter original faces response writer
• @param stringWriter string writer that holds content
• @param writer writer that wrapes string writer
  */
  private HtmlBufferResponseWriterWrapper(ResponseWriter initialWriter, StringWriter stringWriter, PrintWriter writer) { super(writer, (initialWriter == null) ? null : initialWriter.getContentType(), (initialWriter == null) ? null : initialWriter.getCharacterEncoding()); this.stringWriter = stringWriter; this.writer = writer; this.initialWriter = initialWriter; }

/**

• Returns wrapper content as string.
• @return
  */
  public String toString() { writer.flush(); writer.close(); return stringWriter.toString(); }

  }
