error while redirecting the page

[cathymala louis]

Hi

While I am redirecting the control from a jsf page to the servlet to display the image. I am getting the following error.

SRVE0068E: Could not invoke the service() method on servlet Faces Servlet Exception thrown: javax.servlet.servletException.
...
java.lang.IllegalStateExcetpion.

I am getting error while executing the following command in jsf page.

response.sendRedirect("PDFDisplay");

Any pointers towards this error really a great help.

Thanks.
