How do I display the output of a string in JSF correctly?

Question

I have a string in a Managed Bean that I am returning to JSF as output. The returned string is set to output each String component that it consists of on a new line. However, when I pass it to JSF the string prints all on one line. Is there a way to get around this without having to create an individual method (and returned string) for each of the strings that I have combined in the String 'output'?

    public String welcomeDisplay() {
    factory = Persistence.createEntityManagerFactory(PERSISTENCE_UNIT_NAME);
    EntityManager em = factory.createEntityManager();   


    if(true){
        em.getTransaction().begin();

        String sessionEmail=Util.getEmail();
        Query myQuery = em.createQuery("SELECT u FROM BusinessAccount u WHERE u.email=:email");
        myQuery.setParameter("email", sessionEmail);
        List<BusinessAccount> userList=myQuery.getResultList();
        em.getTransaction().commit();
        em.close();

        String bName=userList.get(0).getBusinessName();
        String bAddress1=userList.get(0).getAddress1();
        String bAddress2=userList.get(0).getAddress2();
        String bTown=userList.get(0).getTown();
        String bPhone=userList.get(0).getTelephoneNum();
        String bEmail=userList.get(0).getEmail();

        String output=(bName+"\n"+bAddress1+"\n"+bAddress2+"\n"+bTown+"\n"+bPhone+"\n"+bEmail);

        return output;
    } 


    else {
        addMessage(new FacesMessage(FacesMessage.SEVERITY_ERROR,
                "User Registration Failed!", null));
        return "failure";
    }
}

First of all I think you should rethink your design (separate JSF Managed Beans from your business and DAO layers).
To display the String like you want it, just use <br/> instead of \n. And in your xhtml page:

<h:outputText value="#{yourManagedBean.aPrpoerty}" escape="false"/>

Where aPrpoerty is a String attribute of your managed bean that you set value in the welcomeDisplay method and have a getter for it.
