Hi , I get this exception from tc 3.3.2dev:
java.lang.IllegalStateException: getOutputStream() has already been called

at java.lang.Thread.run(Thread.java:536)
for this code : ( decompiled from work/.../...class )
....
httpservletresponse.setHeader("Cache-Control", "no-cache");
httpservletresponse.setHeader("Expires", "0");
httpservletresponse.setContentType(s1); // s1 depends on the
type of data outputed ( image/gif or text/plain )
httpservletresponse.setHeader("Content-length",
String.valueOf(abyte0.length));
httpservletresponse.getOutputStream().write(abyte0);
}
After this is no output from the jsp, but jasper added an "\n" output to
jspWriter.
The tricky part:
The exception is shown if output TEXT , the TEXT is not outputed.
The exception is NOT SHOWN if i output IMAGE/GIF , but the GIF is!
In both cases the Exception is thrown and logged in stdout.log!
I worked around that problem by outputing texts with out.write() so it does
no longer care, but i think its
a bug in TC..
