使用Jboss AS 7從servlet查找遠程EJB3

Question

是有人可以告訴我程序中的問題嗎：遠程EJB 3是在BonjourEJB3項目中開發的。 BonjourEJB3ClientWeb是一個Web客戶端，它調用遠程EJB3項目。 我不使用Maven。 這是我進行遠程呼叫的方法：

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String nom = request.getParameter("nom");
        String bonjour = "";

    Properties jndiProperties = new Properties();
    jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
    jndiProperties.put(Context.PROVIDER_URL, "remote://localhost:4447");

    try {
        proxy = new InitialContext(jndiProperties);
        bonjourBean = (BonjourService) proxy.lookup("java:global/BonjourEJB3/BonjourBean!com.quesnay.service.distant.BonjourService");
        if (nom != null) {
            bonjour = bonjourBean.ditBonjour(nom);          
        } 
        else {}
    }catch (NamingException e) {
        e.printStackTrace();
    }

這就是讓我進入Eclipse控制台的原因：

Answer 1

顯然，您在EJB客戶端中缺少某些類。

確保您具有ejb客戶端jar的最新版本，並且客戶端包含以下類com.quesnay.service.distant.BonjourService
