What is happening in practice is that: the xml file is indeed updated but
the graph being displayed is an older version (corresponding to the older
.xml file which has now been over-written). I gather that this means tomcat
is caching the xml files.
I have tried including "cachingAllowed" to false in context.xml. I have also
deleted the application_folder under $TOMCAT_HOME\work\Catalina\localhost\.
Neither of these options has helped in disabling caching.
I would really appreciate any help on how I could get around this!
You could add parameter to the URL of the XML file, that changes every
time the file is modified. Something like
src="data.xml?lastModificationTime=20090818000000"
or
src="data.xml?hash=SOMEHASH(data.xml)"
or simply to read file every time, not only when it is changed:
src="data.xml?currentSystemTime=20090818100601"
The change in parameter will force the client to reload the file.
The same thing is possible for CSS, images and other resources.
