public class TeksSurveyPie

extends PJAServlet

This servlet manages in a simple way a dynamic survey and returns the pie of the survey. It can be called in either ways :

• .../servlet/com.eteks.servlet.TeksSurveyPie?survey=mySurvey&answer=myAnswer adds the answer myAnswer to the survey mySurvey, and then returns the pie of the current state of mySurvey.
• .../servlet/com.eteks.servlet.TeksSurveyPie?survey=mySurvey simply returns the pie of the current state of mySurvey.

To be platform independant, the servlet uses com.eteks.awt.servlet.PJAServlet as super class, to have at disposal an image into which graphics operation can be performed.
com.eteks.awt.PJAServlet class and depending classes of com.eteks.awt packages must be in the servlet engine classpath, and at least one .pjaf font file (Pure Java AWT Font) must exist in the user directory or in the directory set in the java.awt.fonts system property, if JVM version <= 1.1.
