[Tianyi W. <wan...@ca...>]

hi:

  i just install the demo with tomcat, it's can display the http://127.0.0.1:8080/jChartsServletExamples/index.html 

  but when i change the code, i reload the pages in brower, it's don't display the changes.

  i want to compile the PieChart2DServlet.java

  but when i use the command:
javac org\jCharts\demo\simpleServlet\PieChart2DServlet.java

  it's tell me 18 errors

  this is the errors info:
