[JBoss Seam] - Enums - Useage
by tony.herstell＠gmail.com
Given:
| <ice:menuItem id="bookingIndoorArenaMenuOption"
| value="#{messages.menu_item_book_indoor_arena}"
| action="#{availabilityController.showAvailability(Resource.instance.ResourceKind.INDOOR_ARENA)}">
| <s:conversationPropagation type="none" />
| </ice:menuItem>
|
| <ice:menuItem id="bookingMenageIntArenaOption"
| value="#{messages.menu_item_book_int_arena}"
| action="#{availabilityController.showAvailability('INT_ARENA')}">
| <s:conversationPropagation type="none" />
| </ice:menuItem>
|
You can see above what I would LIKE to do (pass an Enum to the Controller as a parameter) and you can see what I have to do (and then do some coversion in teh code).
Is there a way to do this in Seam?
| @SuppressWarnings("serial")
| @Entity // Defines this as an Entity that is a class mapped to the Datastore.
| @Name("resource") // Name used within SEAM for an instance of this class.
| public class Resource implements Serializable {
|
| public enum ResourceKind {
| INDOOR_ARENA ("resource_indoor_arena"),
| INT_ARENA ("resource_int_arena"),
| SJ_ARENA ("resource_sj_arena"),
| CONF_ROOM ("resource_conf_room"),
| CAFE ("resource_cafe");
| private final String inlLabel;
| ResourceKind(String inlLabel) {
| this.inlLabel = inlLabel;
| }
| public String getInlLabel() { return inlLabel; }
| }

[JBoss Seam] - Authentication using database accounts
by sztank
Hello,
I'm trying to use Seam to build the application with the following requirement:
PostgreSQL database with a set of defined user accounts (username, password and some privileges granted). The application has to use this accounts to authenticate application users.
For example:
Database has a user "Tom" defined (name, password, privileges ).
When "Tom" login to the application the application should reconnect to the database with username and and password that "Tom" entered.
I wrote that application should reconect but I'm not sure when the Seam application actually connect to the database. I reckon that when it is deployed (is that right?).
Is it possible to implement this scenario with Seam?
This requirement is set by my customer. The reason why to do it that way is to utilize the database build-in users activity reporting. Do you think it is good reason?
ps.
I'm new to Seam and hibarnate.

searched a lot in internet coud not find a tutorial to deploy ejb 3 session beans with a client. there are some but not with jboss, if with jboss then no ejb3. if it is with jboss and ejb3 no help on deployment. also tried jboss.org trailbraizers its very hard to understand...
I have following queries....please help...
what shall be directory stucture to deploy a ejb3 session bean(businessbean and a remote or local business interface) with a simple cilent to communicate with the session bean.
i used presistance.xml and jndi.properties while deploying entity bean.. is there a need of application.xml or ejb-jar.xml or any other .xml to deploy an ejb3 session bean, if yes what shall be their contents.
which .xml files will be needed if the ejbs are deployed as .jar ?.. and .ear?
Im using MyEclipse 5.1, jboss-4.0.5.liferay bundle

[JBoss Seam] - is xhtml a good choice for Facelets templates?
by dan.j.allen
There is a chance that this question is going to be perceived as heretical, but I feel that I either need to speak now or hold my peace.
Is XHTML really a good choice for the file extension and doctype for Facelets templates?
Consider my argument. When we use xhtml as a file extension and include the xhtml doctype, we are saying, "This file validates as XHTML." Well, with all those Facelets tags in there, it sure doesn't. If you use the "jsfc" attribute of Facelets to augment a file that really is XHTML, then maybe that small violation is not so bad. But when the root tag of the file is ui:composition, you are beginning to stray pretty far from the path.
Let me make a suggestion. We can all agree that Facelets templates must be valid XML. JSPX is a valid XML syntax that we can use. But it is sort of verbose and again, we are mixing meanings. How about a new file extension, one that won't confuse the IDEs. How about (f)acelet (c)omposition (t)emplate (FCT)? But then again, should we tie ourselves to Facelets or have a "generic" page extension?
I swear, I am not trying to stir the pot for no good reason. It just seems that calling files XHTML when they aren't isn't such a good idea.
