Seam Newbie Problem

[mutpup]

So I have created a small application just get a basic understanding of SEAM. I have the app deploying without errors.

This must be something simple as by code couldn't be much more basic.

Can someone point me in the right direction? I feel like I'm getting close to having an understanding, but must be missing something pretty basic.

[js8523]

Is there anything that might help in the server.log.

From the information given it should work but the error given doesn't help to much in pointing out the problem area.

Please if you can post more error stacks, etc.

It looks like you are hitting the JSP directly, instead of hitting the faces servlet. (Yes, this is the extremely inelegant way that JSP craps out when that happens.)

I'm not sure if your faces servlet mapping is a good one. Try mapping it to *.jsf or *.seam or whatever, like in the example apps.

[mutpup]

Thanks guys I was able to make some forward progress based on your suggestions. Turns out I was looking at examples from the CVS and using the beta1 code (so I could use 4.0.3SP1). Seems (no pun intended) that it's a rather confusing time right now to start with beta2 about to go out, but only working with 4.0.4 currently.

Anyway I got my page to load up. New road block.

Thanks in advance to anyone who can point me in the right direction...I've gone though all the examples and I must be missing something...

[gavin.king]

If everything else is working, you can ignore that message, I think. Its MyFaces being too verbose.

[mutpup]

Wow. The last java that I wrote was 2 or 3 years ago before I was introduced to Jboss. Everything was TomCat with createing and closing connections and all by hand. Oh how things have improved.

Anyway I'm making really good progress on the learning curve here. But I have a question.

I have created a login page, mostly stealing from the booking example. Everything is working and I kick from my login page to my create user page. The problem is that I am basically carrying on the object that I logged in with. I'm assuming this as all my fields are prepopulated in my form.

I'm also getting the following error when I try and create a new user.

20:30:30,747 ERROR [MethodBindingImpl] Exception while invoking expression #{userutils.createUser}

I want to retain information from my users login, but I also need only users who have logged to have the ability to create users.....so does the create need to be a seperate conversation off the first?

How would I go about doing this, can someone point me in the right direction?

Probably the nicest approach for you is to try out the new @Roles feature that I just committed to CVS. Other approaches include using an indirection between the scoped seam component and the actual User object. So instead of getting the User directly bound to a context variable, you do stuff like #{currentLogin.user} and #{userEditor.user}.

[mutpup]

So I would need a seperate bean to provide access to the entity bean?

Also I think part of my problem is the whole Scope and Stateful/Stateless isn't really gel'd in my mind. Can someone point me in the direction of a page that explains it well?

[mutpup]

eh...I just looked into the roles yeah that is a much better fit.

Guess I'm going to learn how hard it is to build jboss outta the CVS. I will acutally be out of touch with all of this till Monday.

Should I wait, or what is the ETA for the RC of 4.0.4? Will it work with the CVS ver of seam?

[matthew.edwards]

Do a internet search for WinCVS.
Install it.
Start it up.
Press cntrl + L
Copy and paste the cvs location string into the text window and press OK.
You can find it here: http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3917624#3917624

It will download it automatically.
Then browse to the location the project was copied to on your computer.
Select the build folder (or whichever folder has the build.bat file in it) and double click build.bat
It will download what it needs off the internet and then compile itself.

Then copy/paste the generated folder to the location you want JBoss in.

4.0.4 goes out as soon as Scott finishes the QA cycle (ie. gets people to fix some broken tests).

I am basically just in a holding pattern until then :(
