Hello again,
Qiao thank you for your help. I tried copying the WEB-INF(which includes
web.xml) to mms_test but the problem is still there( blank page). I tried
copying the mms_test somewhere else like to ROOT, but the problem still
remains. Just to let you know I can successfull view the page
http://localhost:8080/ but get a blank page when try to access the
http://localhost:8080/mms_test/
And when you try that second link, and you get the blank page, is there
anything in your Tomcat logs ?
I mean, when you try to access http://localhost:8080/mms_test/, there
are only a limited number of possibilities :
- either your browser cannot reach the server. Then you would get a
browser message saying "cannot reach the server". You don't get that, so
we assume the browser can reach Tomcat.
- or the browser reaches the server, and the server cannot find the
requested page (or application), or it cannot access it (permission
problem), or there is an error in the application. Then you would get
an error page from Tomcat. But you do not get that.
- so we have to assume that Tomcat finds "something", and is sending it
back to the browser. That something seems to be an empty page.
But it certainly comes at least with some HTTP Headers from Tomcat.
If there is nothing in the Tomcat logs :
If you are using Firefox as a browser (recommended), get and install the
LiveHttpHeaders plugin. Here :
https://addons.mozilla.org/en-US/firefox/addons/versions/3829
That is a plugin that allows you to see the HTTP Headers that the
webserver is sending along with the response (the blank page).
(If IE, get a similar plugin (Fiddler2 ?).)
Anyway, activate the plugin (in Firefox, LiveHttpHeaders appears in the
Tools menu, just click on it. It opens its own window).
Then just go back to the main window, call up your mmtest link, and look
in the LiveHttpHeaders window, what exactly the server sent.
