[Charts not working/HTML Jasper report from Servlet]

I am meeting this proplem too:

when I use the following link

 

http://localhost:9080/RdzxJbpm/servlet/image?image=img_0_1_0

 

Exception shows the following:

javax.servlet.ServletException: No JasperPrint documents found on the HTTP session.

net.sf.jasperreports.j2ee.servlets.ImageServlet.service(ImageServlet.java:97)

javax.servlet.http.HttpServlet.service(HttpServlet.java:803)

 

 

but if I use http://localhost:9080/RdzxJbpm/servlet/image?image=px

It's no problem

 

can anybody give more message, thx
