Ecrire un XML-RPC demande

Réponse a moi-même: HttpServletRequestWrapper devrait être utilisé au lieu de HttpServletRequest. HttpServletRequestWrapper lit le contenu de HTTP demande et le place dans un membre. Aussi, getInputStream() et getReader() doivent être remplacer par autre versions. Le code irait comme ça:

Code:

class BasicRequestWrapper extends HttpServletRequestWrapper
{
	private String content;
 
        // to wrap the original request
	public BasicRequestWrapper(HttpServletRequest request) throws IOException
	{
		super(request);
		// ... read the whole request.getInputStream() and store it into this.content
	}
 
        // overloads to enable repetitive readings
	public ServletInputStream getInputStream() throws IOException
	{
		final ByteArrayInputStream bais = new ByteArrayInputStream(this.content.getBytes());
		ServletInputStream sis = new ServletInputStream()
		{
			public int read() throws IOException
			{
				return bais.read();
			}
		};
		return sis;
	}
 
        // overloads to enable repetitive readings
	public BufferedReader getReader() throws IOException
	{
		return new BufferedReader(new InputStreamReader(this.getInputStream()));
	}
 
	public String getContent()
	{
		return this.content;
	}
}

Servlet peut utiliser le "wrapper" avec:

public void doPost(HttpServletRequest request, HttpServletResponse response)
{
		BasicRequestWrapper brw = new BasicRequestWrapper(request);
		System.out.println("brw.getRequestURL()=" + brw.getRequestURL());
		System.out.println("brw.getQueryString()=" + brw.getQueryString());
		System.out.println("brw.getContentType()=" + brw.getContentType());
		System.out.println("brw.getContentLength()=" + brw.getContentLength());
		System.out.println("brw.getContent()=" + brw.getContent());
		super.doPost(brw, response);		
}
