Hi to all!

For some time, the language groovy is used to teach the benefits of functional programming.
What is the advantage of using java 8 over languages ​​like groovy/scala?

Thank you,
Francisco.

Hi Bill Gorder!
I did move the contents of the .m2/repository to other folder, and then i did create a new Spring MVC template project.
And after copy the problems.

Sory for my poor english. What is a "bundlor"?
or what do you mean with "bundlor jars" ?

Hello vijayakrishna Mikkilineni and Bill Gorder!
Which template project are you creating? Spring MVC Project (in home.jsp try to show the server time)

Ok, i cut and paste the files ("just in case" for other maven project ) in another location.
This are my "problems" in my problem view.

PS:just mvc-basic/ its going to be my Template? (laugh)

Hi to all.

I download the mvc-basic project from the spring repository and work as well.

Now I trying create a Maven Spring project to zero in eclipse (SpringSource Tool Suite 2.9.2), using "Spring Template Project".
But it get errors: like:
Can not find the tag library descriptor for "http://java.sun.com/jsp/jstl/core" home.jsp
Class 'org.springframework.web.servlet.view.InternalResourceViewResolver' not found

I trying copy the dependencies and sources from pom file of mvc-basic to the template, and nothing.

How can i create a new Spring+Maven Project in a straightforward way?
Or How can i resolve this error?
I don't want Create a Maven and then convert it in a spring project .

thanks for readme!

Hi, to all. I'm using Jsf with Jboss, and i have the same problem.
I try (in head tag):
<link rel="Shortcut Icon" type="image/x-icon" href="/images/favicon-sun.ico" />
but doesn't work.

Thanks !

Hi Tim Holloway, thanks for reply!

I'm newbie in JSF programming but old Java programmer.

Thanks for the example.
Ok : it is a sin if i put logic in JSF instead of the business layer.

i will write again if i have a new doubt .

OK, thanks Ketan Jambhekar !

Hi , to all.

I dont know what is the component that put Commandlink or OutputText (for example ) if a integer property is 1 or 2 (true or false).

<componentUnknow value="#{bean.conditional}">
</h:Commandlink value="Is open!" action="go to the next page">
<h:OutputText >sorry...Is close</h:OutputText >
</componentUnknow>

thanks for readme.!

Hi, Jaikiran Pai, thanks for read me.

why do you mean that my backing bean return String (class) when the property are registered as java.util.ArrayList (the property have Getterand Setter java.util.ArrayList ), and then when i quit the property the data table work?
My eclipse are wrong configured?

Thanks in advance

SOLVED!!!
Jaime Castillo Montes, has the same problem, he solved the problem in:
http://www.lawebdelprogramador.com/foros/JSF/1059058-DataTable.html
Why Work quitting the property ???

I even time understand less and less the JSF.

Tomcat Lie, be cause i put a System.out.println("Hello world") in the constructor, and print it in the console view.
the real error is:
javax.faces.FacesException: Error performing conversion of value ' of type class java.lang.String to type class java.util.ArrayList for managed bean catalogPage.

Why a dataTable expects to receive a String and not a iterable Object?

Hi, to All.

I'm trying to create a dataTable (HTML component)


<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<html>
<head>
<title>Widget Catalog</title>
<link rel="stylesheet" type="text/css" href="css/default.css">
</head>
<body>
<f:view>
<h:form>
<h:dataTable value="#{catalogPage.items}"
var="item"
styleClass="resultTable"
headerClass="header"
rowClasses="oddRow, evenRow">
<h:column>
<f:facet name="header">
<h:outputText value="Code"/>
</f:facet>
<h:outputText value="#{item.code}"/>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Name"/>
</f:facet>
<h:outputText value="#{item.name}"/>
</h:column>
</h:dataTable>
</h:form>
</f:view>
</body>
</html>

but i recive
WARNING: init parameter for skin name changed to org.richfaces.SKIN
SEVERE: JSF1001: Managedbean catalogPage could not be created.
next many Exceptions
What is wrong?

My Enviroment is:
Eclipse 3.4 RS2
Jboos tools
Tomcat 6.0.26
I add custom capabilities (RichFaces 3.3) to the proyect
Thanks for read me.

Problem Resolved!!!

Peter Johnson Thenk you!!! (+1)
You gave me clues to resolve this, be cause i was... (i don't know how really say it in english ) i was in low spirits (no sad).
I download http://www.roseindia.net/jsf/jsf1.2/jsf12.zip

And next In Eclipse .
Windows-->Preferences--->Web-->Libreries:
Click in Mojarra, then, click in Remove.
Click in Add and select all the jars in jsf12.zip (in lib folder)

Create a new Proyect (, new jsf view) and Run it!
Best regards Peter Johnson, from Argentina!

Sorry for the Late!
