Seam 2.0.1.CR2 seam-gen does not create a deployable project

[jsimone]

I just downloaded the latest Seam 2.0.1.CR2 and have been looking at seam-gen. I noticed 2 things:

1. If I execute

seam create-project projname

then I can't override the default build.properties project name with the name projname. I tried setting

project.name=

but that resulted in a seam-gen error. I should be able to specify a name on the gen, no?

2. If I create a new project, then the project created is not a complete deployable project. I would think the least it would do is put up a page at the URL saying "Welcome to Seam". In the spirit of Ruby On Rails, this is what happens when a new ROR project is generated. In the current release when the empty project is deployed we get:


17:54:27,510 ERROR [URLDeploymentScanner] Incomplete Deployment listing:

Did you sun seam setup first?
Did you do as written on the docs?

[jsimone]

yes, I ran seam setup. It all looks ok to me. Here it is ...

Yes, I followed the docs as far as creating the project and then importing into eclipse. I also have the prentice hall "JBoss Seam" book. So are you saying the result of seam-gen should be a working project?

Thanks for listening!

I think I found the problem, but I don't know how to remedy the situation.

If I carefully follow the Seam 2.0.1.CR2 docs in section 2.2 (2.2. Setting up a new Eclipse project) then start JBoss 4.2.2.GA I can't access

http://localhost:8080/helloworld

cause this maps to

http://localhost/helloworld/hello.seam

when I try and go to the first URL. However, WEB-INF index.html has this

content="0; URL=home.seam"

So, when I try and go to

http://localhost:8080/helloworld/home.seam

It works and I get the empty project welcome page.

Why does helloworld redirect to helloworld/hello.seam and where is this defined? I can't find hello.seam anywhere in the project.

Are the docs wrong or is seam-gen creating the wrong redirect URL?

Thanks for listening!

[jsimone]

Copying the facelet home.xhtml in the vew directory to hello.xhtml allow the URL

http://localhost:8080/helloworld

to redirect to

http://localhost:8080/helloworld/hello.seam

seam-gen or the docs are incorrect.

Thanks for listening!

I think you should learn JSF first and get the notion of it first before trying seam.

Well, web.xml has a list of welcome files which are looked for when a web context is hit without a specific page. It finds index.html which immediately redirects to home.seam (I understand that this mechanism is being improved on in the next Servlet spec).

the ".seam"-extension is mapped to the Seam servlet which means seam starts working on "home.xhtml" or "home.jsp" depending on the configured view technology.
