Making a Hello World Flow... what am I missing

[Marten Deinum]

imho it isn't hard... If you just follow the reference guide. The problem is you started with a webflow 1.0 project dumped in the webflow 2.0 jars and didn't work.

The steps on how to configure webflow (flow-executor and flow-registry) are described in chapter 10. How to do the integration with Spring MVC is described in chapter 11. The FlowHandlerMapping should also be the first mapping to be executed (order=0 as mentioned in the documentation).

You are only stating it doesn't work but what doesn't work? Please post errors/stacktraces.

Your sample includes a controller as well as a flow both do the same select the helloworld view to render.

A final suggestion is enable debug logging for org.springframeworkto see what is happening especially the mapping.

Another thing I noticed your servlet is mapped to *.html whereas it should be mapped to / or /*...

I'm not planning on doing your work, I'll give you some pointers but it stops there. I do this in my spare time...

I suggest you take a look at the startup logging especially the FlowRegistry that gives you the id and with that the url under which your flows are mapped.

For more information I suggest you take a look at the webflow sample application (the hotel booking sample) which is basic flow with multiple screens. Nothing to fancy that way you get an idea. You also might want to take a look at [urlhttp://numberformat.wordpress.com/2009/11/09/spring-web-flow-2-hello-world/]this[/url] tutorial (it is for webflow 2.0 but should be almost a 1-on-1 for 2.3).

thanks.. I did not want you to do my work.. but thanks

Well I want to help you but I'm not going to change/fix your code, I will look at your configuration and setup and give the things I notice (and point you to some other resources). I think the last resource I mentioned (the tutorial) should help you to get started, also (but I'm biased on that one) I think our book also does a nice step-by-step introduction which explains all the steps. So basically if you have chapter 10 running you already have something which is more or less your hello world.

thanks.. your book did help and I think everyone should get a copy
