Witam
Moze ktos z Was zajmowal sie wykresami JChart i rozwiazal problem z 
wieloma wykresami zwracanymi przez servlet? Servlet zawsze zwraca mi 
tylko pierwszy wykres - pozostale sa ignorowane. Jak zwrocic kolejne 
wykresy aby byly widoczne w przegladarce?

Oto metoda service() servleta, z ktorej uzyskuje tylko jeden wykres:

public void service( HttpServletRequest req, HttpServletResponse 
response ) throws ServletException, IOException	{
		try
		{
			PieChart2D pieChart2D = new PieChart2D(this.getData(), 
this.legendProperties, this.chartProperties, this.width, this.height );
			ServletEncoderHelper.encodeJPEG131(pieChart2D, 1.0f, response);			
			// tak nie mozna uzyskac drugiego wykresu
			PieChart2D pieChart2D_2 = new PieChart2D( this.getData(), 
this.legendProperties, this.chartProperties, this.width, this.height );
			ServletEncoderHelper.encodeJPEG131(pieChart2D_2, 1.0f, response);			

		}
		catch( Throwable throwable )
		{
			//HACK do your error handling here...
			throwable.printStackTrace();
		}
	}


Bede wdzieczny za informacje

pozdrawiam
Piotr
