[Crystal Reports] IllegalStateException: OutputStream already retrieved

[Alexandre Touret]

Hi all,
I m trying to integrate Crystal Enterprise EE 10 into Oracle Application
Server 10g .

I tested my application in TOMCAT 4.1.31. I use the crystal wiewer
taglib in a JSP. and I use STRUTS 1.2.7

This page is called by an action.

My app works fine on Tomcat 1.1.31 (MS 2K)
But when I deployed my app into OC4J 10.1.2.0.0 I have the following
exception:

java.lang.IllegalStateException: OutputStream already retrieved

Does your action call getOutputStream on the response object at all?
