Need help with RaVis

[Devishree Nair]

Hi,

I am developing a projet where by i have to display data in a
graphical tree format. We are looking for product that will be able to
handle thousands of data in tree view. I came across Birdview and the
RaVis, pretty well suits our requirement.

I am planing to integrate the Flex application in our exisiting J2EE
Project and need your help in this regard. I went through the example
code of RaVis and am tying to see how i can integrate it with Server
side that is mainly written in Java/JSP/Spring/Struts.

In the example, you have generated the xml and the flex is reading the
xml to draw the graph. I was thinking of writing a Java converter
that will generate a GraphML file at the server side and then flex can
read from it to render the Graph, But i have a challenge here as our
organisation doesnt support saving files to the server. In that case
can i make a HttpService call to Java servlet that will send the
graphml data in a result object and then i save this in an object in
action script and render the graph from there. Can you provide more
help in this regard. Or can suggest any other way i can handle this.
Can you also please share if there are any documentation that is
available.

YOur help is highly appreciated.

Thanks,
Rgs,
Devishree.

Devishree,

Basically you have the right idea re: the HttpService call. I'm working on a project now that does exactly this.

The missing function you need is one that takes your XML and creates the new nodes and links (using the createNode() and linkNodes() methods on VisualGraph).

Give it a shot & let us know if you run into trouble.
