Hi,
I am using the below code to regenerate or to get an dynamically generated image:
URL url = new URL(s);
PJAToolkit pjatoolkit = new PJAToolkit();
Image image = pjatoolkit.createImage(url);
where s is the url of the servlet which generates the dynamic .png chart image
i.e s = "http://203.120.153.16/SDS/Chart?Pane1=50;(Study,CBI.N|TRDPRC_1,SMA,200,GREEN,OHLC)&ChartType=HISTORICAL&FillColor=PINK&GridColor=YELLOW&TextColor=YELLOW&DataRepresentation=Charts"
In my case there is not need for the proxy server and port number. I can execute the remote servlet directly without using any proxies.
while exection i am getting the following error, please help me.
java.lang.ClassCastException: sun.net.www.protocol.http.HttpURLConnection$HttpInputStream
com.eteks.awt.PJAGraphicsManager.getImage(PJAGraphicsManager.java:809)
com.eteks.awt.PJAGraphicsManager.createImage(PJAGraphicsManager.java:831)
com.eteks.awt.PJAToolkit.createImage(PJAToolkit.java:607)
MyImg.service(MyImg.java:46)
javax.servlet.http.HttpServlet.service(HttpServlet.java:856)
I am using tomcat server for my servlet execution.

Thanks & Regards
