Re: calling doGet() on the server from a hidden IFrame
Im not doing any parsing of the csv in JS. In my actual app im
writting the text out to PrinterWriter. And doing it this way allows
me to use the standard browser download popups and file navigation. It
works perfectly in hosted and web mode but when deployed to tomcat
doGet() on the server is not being called

Hi Steve,
I would venture it might pay you to read and translate your CSV file
into a List of DTO objects (each, say, representing a line of CSV
text) within a GWT RPC method that sends this List back over the wire
- GWT RPC will handle all that for you. Easier, and I think parsing
the CSV might be quicker on the server in Java than slogging through
it on the client in javascript. Also, depending on your use case, you
might be able to cache it server side.
If that doesn't work for you, then look at
com.google.gwt.user.client.HTTPRequest docs.

client code is:

my server has the doGet method:

And as i said i think this is almost certainly a config issue but i
cant seem to work it out. my web.xml currently contains:

Hi Steve,
I would venture it might pay you to read and translate your CSV file
into a List of DTO objects (each, say, representing a line of CSV
text) within a GWT RPC method that sends this List back over the wire
- GWT RPC will handle all that for you. Easier, and I think parsing
the CSV might be quicker on the server in Java than slogging through
it on the client in javascript. Also, depending on your use case, you
might be able to cache it server side.
