[JBoss Seam] - Re: Praise for Seam
by SmokingAPipe
(Woops, I hit submit before I was ready.)
Anyway, so that's the bean.
And then I have this in foo.jsp:
<f:view>
| <p>
| <h:outputText value="#{requestBean.message}" />
| </p>
| <f:view>
|
Should always work, right? The requestBean has EVENT scope, so it's available in every page. "message" is obviously a property of the RequestBean, because it has a getter and setter.
But it does not work. I get this exception:
javax.faces.el.PropertyNotFoundException: Expression: '#{requestBean.message}'
| at org.apache.myfaces.el.ValueBindingImpl.getValue(ValueBindingImpl.java:392)
|
Seam is fragile. From the docs, EVENT scope means "every request". The property is there. How can Seam not find it?

[JBoss Messaging] - RC3 stable? which jdk? ad on: mssql-persistence-service.xml
by Josef＠logistikpur.com
hello,
we are using
jboss-4.0.4.GA
win xp sp2
Microsoft SQL Server 2000 - 8.00.760
jboss-messaging-1.0.1.CR3 and it works fine for us.
now the questions:
1.
we run jboss-4.0.4.GA (install: jboss-4.0.4.GA-Patch1-installer.jar default)
under jdk1.5.0_07 (jdk-1_5_0_07-windows-i586-p.exe; build 1.5.0._07-b03)
is this the right jdk?
2.
is it a good idea to use jboss-messaging-1.0.1.CR3 in a production environment?
3.
what content will have the destinations-service.xml in a production environment?
4.
when will the first jboss-messaging-x.y production release be available?
5.
some benefit: following, is my "mssql-persistence-service.xml"; all tests passed :-)
please check the file and reply when there are things wrong!

[JBoss Seam] - When are components created?
by SmokingAPipe
I created a very simple component like this:
| @Name("requestBean")
| @Scope(ScopeType.EVENT)
| public class RequestBean {
| private static final Logger logger = Logger.getLogger("RequestBean");
|
| public RequestBean() {
| logger.info("Created a request bean!");
| }
|
| private String affiliateId;
|
| @RequestParameter
| public String getAffiliateId() {
| return affiliateId;
| }
|
| public void setAffiliateId(String affiliateId) {
| logger.info("Setting the affiliate id param: " + affiliateId);
| this.affiliateId = affiliateId;
| }
|
| }
|
It would seem that, because the scope is EVENT, this bean would need to be instantiated for every single seam request, and yet I never see it get instantiated. Various other beans do get instantiated, and I'm not sure how Seam decides.
Also, what is the use of the @RequestParameter annotation? I've put in in various beans (stateful, stateless, entity, JavaBeans, etc) and it never gets called. Is there a way to get access to request parameters?
All I want to do is have it so that if a user shows up at the site, the affiliateId (which is in a GET parameter) gets saved in a cookie. Shouldn't be this hard but I can't figure out how to even access the parameter within Seam, or even get Seam to instantiate my component.
Any suggestions welcome.
