I guess your question might be the better one. Along with the "what" would be:

When would I want to use JSF or AJAX in an environment like Yahoo?

Excuse my ignorance... I guess I am looking for that selling point. As a developer, we have many tools and avenues to accomplish our task. I haven't had any real exposure to see a need to use AJAX or JSF or Java for webpages on a smaller scale. I think some of it comes from not writing a small "useable" model. Like say a Pet store or something like a "file cabinet" application of storing newsletters, etc.

JSF
Keeping it simple...

Say I use both ort one of them. And I have a website with someone like Y@hoo who is hosting it. And everything drives from that site which has MYSQL, PHP, Perl, HTML/XHTML and CSS support.

Would JSF and AJAX fit into an environment like that to be useful? :roll:

I have read the Amazon dot com Editoral Reviews.

I had thought about loading JBoss on my PC at home. Thinking it might be helpful for developing use with web pages.

My dumb questions are;
Would this be helpful if I were to develop webpages for potential clients?
Are there any special considerations I might need to help make this decision?
Do you have a check list to help make a choice for using JBoss verses what it is qould replace or enhance?

Thanks,

I also sent Barry this email and he replied that he had not worked with this in a long time;

On this web page you made a reference;

https://coderanch.com/t/46371/Struts/struts-installation

On this line of;

quote:
--------------------------------------------------------------------------------
The structure should be c:\tomcat\webapps\struts\jsp and c:\tomcat\webapps\struts\WEB-INF. Right?

--------------------------------------------------------------------------------



I have;
WebSphere Studio Application Developer (Windows) Version: 5.1.2
using Apache Tomcat Support 5.1.1
Struts Tools 5.1.2

I have the information laid out like the previous posts talk about. Except I do not have tomcat laid out in the folder order you mentioned. I just added CVS Repository to my PC. That seems to have been when this started.

Do you have a list suggestion of what needs to be laid out in what order with my config?

Thanks in advance,

Let me make a small correction. I am using LDAP security.

The welcome page is successful. The login is successful. etc...

More to the point. How would I check in the JSP (at the Welcome page) if the user had logged in?

Or would you check it that way?

I've been struggling with this.

The environment contains WSAD 5.1.2, jsp, struts.

Thanks,

If you were setting up jsp's and Action Classes... where would you set up the "Locale" that denotes what language that you are using for the session and possibly changing it during the session. With the ability of the jsp being able to read it back.

Quite simply... say you sign in using Spanish... you are working along and you want to show a co-worker/client what you have and switch it over to English. You are done with your coworker/client and switch it back to spanish and continue your work. Or you could do it the other way around.

How would you accomplish this? I am trying to keep it simple by managing the "words/phrases" in PropertyResource files. What I am using is WebSphere Studio Application Developer (Windows) 5.1.2 and Struts tag libs.

Thanks,
Alex

P.S. I was trying to look in the welcome page to see if I already assigned a language to it... if I did then I could redirect it to the main menu page. But... as I said... I am getting nulls back from the Locale.

Thanks again,

I am creating a test to allow you to sign in and get a welcome page (jsp) that will ask if you with to Navigate (via a link) in English or Spanish (kinda like an ATM). Then it will go to the login form page (jsp) for (drop down) name and password. And it should go to the main menu (jsp) page. That is where it is not going. It goes back to the welcome page.

Here are the jsps;

I think I got an answer to this. But I am trying to work out a different problem that I will post seperate from this. Then I can come back to this issues and see if it is right.

The answer was to create a Dispatch Action Class. Using the key information in the ApplicationResource folders rather than the value i.e.;

prompt.Name

= Nombre
not the value of

prompt.Name

but the key itself. As the key is the same in both ApplicationResource files.

Thanks for at least looking at this,
Alex :roll:

First post...

I sure hope this is an easy question.

How can you develope in a Java Action Class to grab information that you have coded (from the jsp), such as;

<INPUT TYPE=SUBMIT NAME="BUTTON"
VALUE=<bean:message key="mainMenu.date"/> class="buttonstyle">

to find out what the Value is?

Especially if you are using two different Application.Resource files (English and Spanish).

Thanks,
Alex
