I'm using JBoss 4.0.2
Here's my JSP source:
<% java.io.OutputStream os = response.getOutputStream(); %>
That's the entire thing. Here's what I get:
java.lang.IllegalStateException: getOutputStream() has already been called for this response
org.apache.catalina.connector.Response.getWriter(Response.java:596)
org.apache.catalina.connector.ResponseFacade.getWriter(ResponseFacade.java:186)

org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:81)
It looks like org.apache.catalina.connector.Response.getWriter() is trying to make a call to response.getOutputStream when it shouldn't.
Anyway, is there anyway to send binary data to a client using JBoss? (I'm using POI HSSF and iText for creating Excel and PDF docs.)
