I have two templates in my web project. I want to use a different PrimeFaces theme for each template.

How do I do this?

No web.xml , when I put the theme of PrimeFaces it changes to all templates, but I want each template to have a theme.

You can do all this processing in ManagedBean . For example:

UserMB:

@ManagedBean
@SessionScoped
public class UsuarioMB {

    private String templateSelecionado = "templateDefault.css";
    private String temaSelecionado = "temaDoTemplateDefault";
    private List<String> temasDisponiveis = new ArrayList<String>();

    @PostConstruct
    public void init() {
        if(condicao) { //condição para trocar de tema/template
            templateSelecionado = "templateDiferente.css";
            temaSelecionado = "temaDoTemplateDiferente";
        }
        //Populando os temas
        temasDisponiveis.add("casablanca");
        temasDisponiveis.add("cupertino");
        temasDisponiveis.add("bluesky");
    }

    //getters & setters
}

template.xhtml

<h:outputStylesheet library="css" name="#{usuarioMB.templateSelecionado}" />

pageToSelectTema.xhtml

<p:themeSwitcher value="#{usuarioMB.temaSelecionado}">
    <f:selectItems value="#{usuarioMB.temasDisponiveis}" />
</p:themeSwitcher>

web.xml

<context-param>
    <param-name>primefaces.THEME</param-name>
    <param-value>#{usuarioMB.temaSelecionado}</param-value>
</context-param>

Explanation :

Using the templateSelecionado and temaSelecionado attributes, both of type String , you can dynamically modify both the css and the theme of PrimeFaces.

Simply make the <h:outputStylesheet> tag use the templateSelecionado attribute and make the page that changes the theme (containing the <p:themeSwitcher> component) and web.xml use the temaSelecionado attribute. / p>
