嗨，我试图开发一个登录页面使用oracle jdeveloper 12c和。我正在使用JEE技术和JSF页面。
我想在按下身份验证按钮后重定向到主页，但它不起作用，我得到这个异常:
javax.servlet。ServletException: ADF_FACES-60101:Code de statut d " error HTTP: 404。"
这是我在ejb部分中的身份验证函数
public String authentification(String login, String pwd) {
try{
Query query;
query = em.createQuery("select o from UserEntity o where "
+ " o.login = :LOGIN AND o.pwd = :PWD");
query.setParameter("LOGIN",login);
query.setParameter("PWD",pwd);
query.getSingleResult();
return ("success") ;
}
catch(Exception e){
e.printStackTrace();
return null;
}
}
这是我在被管理bean中的loginaction
public String loginaction() {
FacesContext ctx = FacesContext.getCurrentInstance();
HttpServletRequest request =
(HttpServletRequest)ctx.getExternalContext().getRequest();
String Url =
"/adfAuthentication?success_url=/faces/Main.jsf";
HttpServletResponse response;
response = (HttpServletResponse) ctx.getExternalContext().getResponse();
RequestDispatcher dispatcher =
request.getRequestDispatcher(Url);
try {
dispatcher.forward(request, response);
} catch (IOException e) {
FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_ERROR, "Invalid Username or Password", "Invalid Username or Password");
ctx.addMessage(null, msg);
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
这是我的jsf
<af:panelFormLayout id="pfl1">
<af:inputText value="#{bindings.login.inputValue}" label="#{bindings.login.hints.label}"
required="#{bindings.login.hints.mandatory}"
columns="#{bindings.login.hints.displayWidth}"
maximumLength="#{bindings.login.hints.precision}"
shortDesc="#{bindings.login.hints.tooltip}" id="it1">
<f:validator binding="#{bindings.login.validator}"/>
</af:inputText>
<af:inputText value="#{bindings.pwd.inputValue}" label="#{bindings.pwd.hints.label}"
required="#{bindings.pwd.hints.mandatory}"
columns="#{bindings.pwd.hints.displayWidth}"
maximumLength="#{bindings.pwd.hints.precision}"
shortDesc="#{bindings.pwd.hints.tooltip}" id="it2">
<f:validator binding="#{bindings.pwd.validator}"/>
</af:inputText>
<af:button actionListener="#{bindings.authentification.execute}" text="authentification"
disabled="#{!bindings.authentification.enabled}" id="b1"
action="#{Login2.loginaction}"/>
</af:panelFormLayout>
这是我在服务器仪表板中得到的

从日志中我看到它不仅仅是一个简单的JSF，而是一个基于ADF的应用程序。我可以想到两种方法来实现重定向到一个页面:
1。您可以在adfc-config.xml(甚至faces-config.xml)文件中定义一个导航规则，然后，只需将此定义规则的名称作为按钮的action属性值。
2. 如果您希望使用编程方法，那么您可以调用返回这种字符串的代码"mainPage.jsf?faces-redirect=true"，因为adf添加了自己的上下文。例如:
public String loginaction() {
........
return "mainPage.jsf" + "?faces-redirect=true";
}
注意:您可能需要添加"/faces/mainPage"。/faces/…/mainPage. jsf"或"/faces/…jsf"。这实际上取决于参与导航的两个页面的位置。根据调度程序部分，它与JSP一起使用。不需要也不建议再使用它了。
