I see. Do you have any errors in our log files (Tomcat/Webapp), e.g.
about response already committed? It seems something either is sending
the headers to the web server before the code sets those headers above,
or they get reset after setting them. E.g. if the code under any
condition calls flushBuffer() before setting those headers, the response
will already be committed and you can't set the headers later on. Any
call to getWriter() also makes it impossible to set headers later.
If there are no error messages, you could try to check via isCommitted()
before setting the headers to see, whether this assumption is true or not.
You can also use register a ServletResponseWrapper in a filter to
intercept the calls to the ServletResponse and to debug, why and when
the response got committed prematurely (and also to see, whether your
setContentType() got actually called.

Not sure, what that shows exactly, but you can set the log level of the
connector components higher by adding
org.apache.coyote.level = FINEST
org.apache.jk.level = FINEST
org.apache.tomcat.level = FINEST
to conf/logging.properties.
The log will then also contain messages like
Dec 8, 2008 4:00:05 PM org.apache.jk.core.MsgContext action
FINE: COMMIT
Dec 8, 2008 4:00:05 PM org.apache.jk.common.JkInputStream appendHead
FINE: COMMIT sending headers [EMAIL PROTECTED] ===
MimeHeaders ===
ETag = W/"16763-1201552728000"
Last-Modified = Mon, 28 Jan 2008 20:38:48 GMT
So you can see the headers sent out by Tomcat.

Rainer
