Hi All,
I'm trying to use ehcache-web 2.0.3 with apache-cxf 2.3.3 and Tomcat 6. There
doesn't seem to be much in the way of information online about it and I
wondered if anyone else had tried it. I have an issue where for the first,
uncached request I get the following error:
net.sf.ehcache.constructs.web.AlreadyCommittedException: Response already
committed after doing buildPagebut before writing response from PageInfo.
Subsequent requests are returned correctly by the cache until the cache content
goes stale and then we get the same error above.
Googling turns up similar issues that seem to have subsequently been fixed for
WebLogic but no issues have been reported for Tomcat.
I'm not massively knowledgeable about the internals of Tomcat's
request/response pipeline but it seems to me that when ehcache records a cache
miss, it passes the request down the line to the CXF servlet but CXF commits
the response before ehcache has a chance to modify the response headers.
I've got a pretty simple web.xml at the moment (see it at the end of this
email). Can anyone cast any light on this? How can I ensure that CXF doesn't
commit the response before the end of the filter chain?
I've already tried adding:
<dispatcher>REQUEST</dispatcher>
<dispatcher>INCLUDE</dispatcher>
<dispatcher>FORWARD</dispatcher>
to my filter mapping but it didn't appear to make any difference.
Thanks very much,
Matt
