Summary: ResponseOverrideFilter kills CSS in Struts templates
Initial Comment:
Hello -
I'm using WebLogic 8.1 SP2 with Struts 1.1 templates.
When I try to get the ResponseOverrideFilter to work
with exports, I get an exception.
Servlet failed with Exception
java.lang.IllegalStateException: strict servlet API:
cannot call getWriter() after getOutputStream().......
This exception is being thrown from the line in
ResponseOverrideFilter that is:
PrintWriter out = servletResponse.getWriter();
Which is funny because getOutputStream() is never called...
But the real funny thing is that whenever this filter
is implemented in my web.xml, the generated HTML from
my Struts servlet ignores the CSS stylesheet and
therefore all the style is lost for the entire page.
Now, this only happens in Netscape 7.1
In IE 6 and Mozilla Firebird, the page is not even
displayed...I get a different exception:
java.net.ProtocolException: Exceeded stated
content-length of: '0' bytes

Hi, folks.
The b3 snapshot contains a new version of
BufferedResponseWrapper that partially fixed the
IllegalStateException problem but introduce a new one. I
modified the flushBuffer() method to look like this:
public void flushBuffer()
{
output.flush();
getWriter().print(this.servletOutputStream.toString());
this.servletOutputStream.outputStream.reset();
}
Once in a while, Weblogic 8.1 calls flushBuffer() and
getOutputStream(). Without the 2nd line, some of the original
output will be accidentally thrown away. I merged the b3
version's BufferedResponseWrapper into b2 source code,
applied my patch and now everything works fine under
Weblogic 8.1, Struts 1.1 (with Tiles). I can send you my
patch if you need it.

Yes, I was using display tag b2 release. But I downloaded the
latest b3 snapshot and did two tests: First I tried the bundled
displaytag-examples.war, turn on the response filter in
web.xml and there's no IllegalStateException. Second, I try
my own Struts example with b3 release and nothing comes
out from the first page (index.jsp). I'm encountering the same
problem that Eric ([EMAIL PROTECTED]) is having (date: 2/27).

addisonlin - can you conifirm that this is happening with
the nightly build release? Or are you using the b2 release?
The fix went in after the b2 release.

Hi, I'm encountering the exact same problem. But I'm using
IE6. I'm also using Weblogic 8.1 SP2 and Struts 1.1. Is there
a quick fix for the problem? I've tested it with Weblogic 6.1
SP3, Tomcat 4/5, there are no such problem with these
platforms.

I've got the same problem using WebLogic 7.0 SP3.
B3 fixed the "java.lang.IllegalStateException: strict servlet
API: cannot call getWriter() after getOutputStream()......."
message
but now nothing is shown in the browser (IE6 SP1)
HTML result :
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0
Transitional//EN">
<HTML><HEAD>
<META http-equiv=Content-Type content="text/html;
charset=iso-8859-1"></HEAD>
<BODY></BODY></HTML>
for each page that is filtered by ResponseOverrideFilter even
if this page doesn't contain displaytag
