Jeff Genender reassigned GERONIMO-1084:
---------------------------------------
Assign To: Matt Hogstrom
Lin, are you using the most up-to-date version of the day trader because your
line numbers do not match what is in the source repo. In anycase, the Tomcat
container is very strict and follows the servlet spec exactly. The servlet spec
says:
"SRV.14.2.22.1
getOutputStream()
<SNIP>
Either this method or getWriter() may be called to write the body, not both.
</SNIP>
throws:
IllegalStateException - if the getWriter method has been called on this
response"
I have not looked at the Trader code in detail, but I assume the getWriter()
was already calling either a forward or one of the includes, thus I think this
is an issue with the Trader app. That line you pointed should probably be
changed to use getWriter(). I will assign this to Matt to look at.
