Cannot create a session after the response has been committed
Hello,
I use tomcat4.1.24, cocoon 2.0.4 and JDK1.3.1_07 on Win2000 test system and Solaris. On Win2000 everything works fine, but on Solaris I get the following exception:

Re: Cannot create a session after the response has been committed
Posted by Geoff Howard <co...@leverageweb.com>.
Looks like the problem is in GetSessionAttributes.xsp and probably means
you forgot to add the create-session=true attribute onto the xsp
element. (both the attribute name and the exact element name I just
used are probably wrong - look them up in the docs/wiki).
However, since you are using cinclude you may also find that you do have
that attribute set correctly but previous pipeline bits are being
committed before you get to your xsp. If that is the case, I don't
quite remember how to fix this (besides rearranging your pipeline, or
making sure a session exists before it's executed), though you should
find some pointers in the archives of this list.
Send the first few lines of that file if you need more help than that.
By the way, this is probably not really system dependant. I'd expect
that on your test system you already had a session (is tomcat persisting
sessions across startups?) and therefore didn't have the error condition.
