Writing to an XML file
Hello everyone, I'm new in GWT, and I can not solve a problem. I can not write to an XML file. I tried to look at the documentation but I did not understand much. Someone can give me a hand?

Reading/Writing a public XML file at the server side
I'm working on a GWT application and previously I was simply reading and writing to the file data.xml, which worked fine at that point. However now I want to have the file available publicly (i.e. by replacing mymodule.html with data.xml in the URL), and I'm now having difficulty with reading/writing the file whilst using the hosted mode browser. I achieved making the file public by adding the file to my Eclipse project under the public directory and then adding public path=public/ / to my module.gwt.xml file, so now I can change the URL in the hosted mode browser and view the contents of the file. Now, however, I would also like to read and write the same file that is public. I tried using getServletContext().getRealPath(data.xml) but the returned path doesn't exist. Any ideas?

Re: Reading/Writing a public XML file at the server side
Hey, In GWT 1.6, you don't need to put files into your app's source
folder; instead, put it directly into the war folder. In this way,
the HostedMode server will know to update when the file changes, as
opposed to having to manually recompile the file every time you write
to it. Consider using a static String to point to your local
harddrive location of the war folder, and just change this string to
your external server's filestructure when you compile a production
build.
If you like, you could even use a deferred binding property,
isLocalHost to automatically change this string...
define-property name=isLocalHost values=yes,no/
property-provider name=isLocalHost![CDATA[
if (window.location.indexOf('localhost')==-1)return 'no';
return 'yes';
]]/property-provider
Then, just do deferred binding on this property to replace your file
pointer......Oh wait, you need this server side.
Just use String fileHome = request.getDecodedRequestURI().contains
(localhost)? /home/localuname/workspace/proj/war/ : /home/
serveruname/public_html/; Or likewise. Who knows, maybe using war
instead of src folders will make getRealPath work too...
