Here's my problem:

In the xhtml below (list.xhtml) when I put it this way, it does not recognize the method I did in my Bean (the bean method returns a list). The JSF together with the primefaces is shown on the screen perfectly, only not returning the data (No records found).

<?xml version="1.0" encoding="UTF-8"?>
<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:p="http://primefaces.org/ui">
<h:head>
</h:head>
<h:body>
    <h:form>
    <p:commandButton value="Listar" actionListener="#{MBean.retornaOSsPorCliente}" styleClass="ui-priority-primary" />
        <p:dataTable var="sza" value="#{MBean.list}">
            <p:column headerText="Cliente">
                <h:outputText value="#{sza.ZA_CLIENTE}" />
            </p:column>

            <p:column headerText="Funcionário">
                <h:outputText value="#{sza.ZA_CODFUN}" />
            </p:column>
        </p:dataTable>
    </h:form>
</h:body>
</html>

Below the screen that does not show the data:

}

Attempts to remove <managed-bean>...</managed-bean> from faces-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<faces-config xmlns="http://xmlns.jcp.org/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd"
    version="2.2">

</faces-config>

The @ManagedBean annotation plays the role of pointing to the class as a manageable bean. Also try removing the property (name="MBean") from @ManagedBean. By default, on the screen JSF will present its BEAN with the name of the small class # {mBean.metodo ()}.

Firstfaces did not recognize the methods because you did not add the methods to faces-config along with your Bean. This is why you only use the @managedBean annotation and do not map your Ben in faces-config. Because with the annotation already solves these problems of mapping.

Also, on your <p:commandButton value="Listar" actionListener="#{MBean.retornaOSsPorCliente}" styleClass="ui-priority-primary" update="myDataTable" /> button, I recommend that you put an ID for your DataTable and have an update on that id update="myDataTable" button.
