Hi.

First of all, I read the topic http://faq.javaranch.com/view?IllegalStateException. But still in doubt since my scenario goes like this:

#1. Web application, using RAD and Struts (servlets, filters, actions, and so on....)
#2. A request to generate a PDF, after the Action.execute processing, works like this:


#3. After the execution above, my filter is throwing the exception whit the warning:


WARNING: Cannot set status. Response already committed.
WARNING: Cannot set header. Response already committed.
javax.servlet.ServletException: getOutputStream() has already been called for this response
at com.ibm.ws.webcontainer.filter.WebAppFilterChain.doFilter(WebAppFilterChain.java:166)
at com.ibm.ws.webcontainer.filter.WebAppFilterChain._doFilter(WebAppFilterChain.java:87)


What should I do to avoid this cenario?

RegardĀ“s,
Rafael.


Thanks,
Rafa

We solved a similar exception related with sendredirect using lady4j. In our case the problem was that we already retrieved the outputstream and we tried to redirect... be careful with that.
