Use Jetty on WildFly 39.0.1

[Roger Lee]

I have an issue the PrimeFaces Jakarta Java Faces components on Mojarra 4.0.13 & Undertow 2.3.23.Final. Specifically  "p:ajax" & "p:tabView".

The test & examples work fine on Jetty:

mvn clean package -Pnon-ee,mojarra-4.0

How easy is it to switch to Jetty & any guides? TIA 

[James Perkins]

You can't use Jetty and WildFly together. They are both Jakarta Servlet servers, but WIldFly is a full Jakarta EE server as well. WildFly uses Undertow for it's Jakarta Servlet implementation.

Are you seeing errors if you try to use WildFly?

[Roger Lee]

II've  been using WildFly from the JBoss days (3.x from 1999) & also JSF/Java Faces from RichFaces 3.1 & had to move PrimeFaces in 2012, started with 5.x. Currently using WildFly Distribution - 39.0.1, Mojarra 4.0.13, Undertow 2.3.23.Final & PrimeFaces (Jakarta) 15.0 13.

I've always had issues with 'p:tabView/p:view' since migrating from RichFaces. Now I have issues with 'p:ajax'.

No errors or exceptions, just won't select & display 'p:selectOneListbox/p:selectOneMenu' & want 'p:ajax'.to use event/listener to call my Controller

Just looking for some alternatives. TIA.

[James Perkins]

Ah, I see. This is definitely not my area of expertise so I'm not too sure what would cause that :) If you have some form a reproducer that can be shared, I'm happy to have a look though.

[Jason Lee]

I just opened a PR to merge Mojarra 4.0.15 for WildFly 40, which includes this change that might help you: https://github.com/eclipse-ee4j/mojarra/commit/867a942e6aa5c22fef56134a9f011249f3e3a179

If you want to try it now and not wait for 40 you can replace

$WILDFLY_HOME/modules/system/layers/base/jakarta/faces/impl/main/jakarta.faces-4.0.13.jar

With https://repo1.maven.org/maven2/org/glassfish/jakarta.faces/4.0.15/jakarta.faces-4.0.15.jar

You can either overwrite the file (thus keeping the name) or, better, and this jar to that directory and change the version in modules/system/layers/base/jakarta/faces/impl/main/module.xml The latter makes reverting a bit easier.

Updating the module like that isn’t really a supported approach (as in, do this at your own risk), but users do that pretty frequently for small fixes like this one safely. 

If it works, it gets you a fix now and then you can update when WF 40 ships and that fits into your schedule, and, if it doesn’t, we know to keep looking for a fix. :)

Let me know how that goes.

I upgraded from Mojarra 4.0.13 to 4.0.15.

INFO  [jakarta.enterprise.resource.webcontainer.faces.config] (ServerService Thread Pool -- 108) Initializing Mojarra 4.0.15 for context '/ViViFYd'

No issues, but 'p:ajax' doesn't execute my 'Controller'. Will continue looking. TIA.

I've tried both using: p:ajax & f:ajax with: p:selectOneListbox

on my 'Controller':

public void handleCharactersChange(ActionEvent actionEvent) {

&

public void handleCharactersChange(Object object) {

Hi,

I think u can use omnifaces.SelectItemsConverter, or create a converter., to be clear this is not a problem from wildfly 39 or other version.

@Jose. After upgrading to 'Mojarra 4.0.15' it has show an Error. Looking at your example it highlighted my error is probably with the/no 'converters'. 

public Converter<GasStationTO> getSelectedGasStationSupport() {

I thought that I could use the OmniFaces 'ListConverter' as:

<p:selectOneListbox
id="archersCharacters"
converter="omnifaces.ListConverter"
value="#{daily.theArchersCharactersString}">

However when I 'click' on my 'selectOneListbox':

<p:ajax
    listener="#{theArchersDailyRSSController.handleCharactersChange}"
    process="@this"
    update="panelCharacterSelect"/>

I get:

An Error Occurred:

Cannot invoke "java.util.List.iterator()" because "this.list" is null

Looks like I need to create my own 'Converter'. 

Thanks.

BTW - I've used other Omnifaces converters  before . NOT "omnifaces.SelectItemsConverter".

[Jose Socola]

Here is the main problem, u can't use the same variable for both 

    value="#{daily.theArchersCharactersString}"> change to String or Object

            <f:selectItems
                value="#{daily.theArchersCharactersString}"

Hello Jose,

Can you explain with "u can't use the same variable for both ". If I don't use 'theArchersCharactersString' on both 'values' one is not displayed.

Hi Roger,

country is a String and countries is a List<String> on showcase

@Named @RequestScoped public class SelectOneView { private String option; private Country country; private List<Country> countries;

...

<h5>Advanced</h5> <div class="col-12 md:col-6 lg:col-4 xl:col-3"> <p:selectOneListbox id="advanced" value="#{selectOneView.country}" converter="#{countryConverter}" var="c" filter="true" filterMatchMode="contains" filterNormalize="true"> <f:selectItems value="#{selectOneView.countries}" var="country" itemLabel="#{country.name}" itemValue="#{country}"/> <p:column> <span class="flag flag-#{c.code}" style="width: 30px; height: 20px"/> </p:column> <p:column> <h:outputText value="#{c.name}"/> </p:column> </p:selectOneListbox> </div>

In your code u use the same variable for both, 

<p:column width="10%" headerText="selectOneListbox - Select Characters">
    <p:panelGrid id="charactersListPanel" style="height:100%">
        <p:selectOneListbox
