Hi,
I'm using FusionCharts v3 with GWT and am trying to get real-time updates from the DB.
(an XML won't work because I need user specific data display)
I can't seem to make a plan old servlet call in my Data.xml (ex. dataStreamURL='http://localhost:8888/com.ints.central.ui.Dashboard/Ticket) to a ticket servlet because GWT complains.
I can't make a GWT RPC call because there doesn't seem to be a way to feed the result into the data feed.
I can't seem to make a JS to Java call in GWT because GWT is managing my entire app and I don't have a "page centric" model. GWT does everthing in one page.
I'm considering Java -> JS call but managing the timing of the updates from Java seem like an awful option.
Has anyone done anything similar or have any ideas? I would really like to buy a site license for GWT but can't unless we solve this problem.
Mark

| It can be done. Your RPC call should retrieve a result from a query. From there, pass that result (in an arraylist or something) into your GWT code that generates your fusion chart. I suggest you use Java code to wrap the fusion chart xml elements and generate them through xml parser. I have this working, although I'm working on an other issue relating to IE.

Hi,
In my J2EE application some servlets produce the xml expected by the fusion chart.
I published on google code a framework for using FusionChart in GWT application.
http://code.google.com/p/gwt-fusionchart/
The project is under the LGPL licence.
Regards,
Seb
