我正在 IBM Worklight 平台上试验基于表单的身份验证，我目前正在学习位于此处的教程。
我有一些奇怪的行为，第一次尝试登录时它只会重新加载登录页面，但如果我第二次尝试使用完全相同的详细信息，它就可以工作。这种行为是一致的，我每次都能重现它。
仔细观察 JS 控制台，我可以看到正在打印：
openjpa-1.2.2-r422266:898935 nonfatal user error> org.apache.openjpa.persistence.InvalidStateException: The factory has been closed. The stack trace at which the factory was closed is available if Runtime=TRACE logging is enabled.

搜索该堆栈跟踪揭示了一个先前的问题SO，据此建议某些东西正在调用close(). EntityManagerFactory我不确定这是在哪里/为什么会发生，因为所有这些都将在 Worklight 下进行管理。
这是我用于身份验证过程的 JS，在js/auth.js
var Authenticator = function() {
var LOGIN_PAGE_SECURITY_INDICATOR = 'j_security_check';
var USERNAME_INPUT_ID = '#usernameInputField';
var PASSWORD_INPUT_ID = '#passwordInputField';
var LOGIN_BUTTON_ID = '#loginButton';
function onFormSubmit() {
WL.Logger.debug("Entering auth.js.onFormSubmit()");
var reqURL = './' + LOGIN_PAGE_SECURITY_INDICATOR;
var params = {
j_username : $(USERNAME_INPUT_ID).val(),
j_password : $(PASSWORD_INPUT_ID).val()
};
onSubmitCallback(reqURL, {
parameters : params
});
}
return {
init : function() {
WL.Logger.debug("Inside auth.js.init");
$(LOGIN_BUTTON_ID).bind('click', onFormSubmit);
},
isLoginFormResponse : function(response) {
WL.Logger.debug("Inside auth.js.isLoginFormResponse " + response.responseText);
if (!response || response.responseText == null) {
WL.Logger.debug("Entering auth.js.isLoginFormResponse (), return false");
return false;
}
var indicatorIdx = response.responseText.search(LOGIN_PAGE_SECURITY_INDICATOR);
WL.Logger.debug("Entering auth.js.isLoginFormResponse (), return " + (indicatorIdx >= 0));
return (indicatorIdx >= 0);
},
onBeforeLogin : function(response, username, onSubmit, onCancel) {
WL.Logger.debug("Inside auth.js.onBeforeLogin");
onSubmitCallback = onSubmit;
onCancelCallback = onCancel;
if (typeof (username) != 'undefined' && username != null) {
$(USERNAME_INPUT_ID).val(username);
} else {
$(USERNAME_INPUT_ID).val('');
}
$(PASSWORD_INPUT_ID).val('');
},
onShowLogin : function() {
WL.Logger.debug("Inside auth.js.onShowLogin");
$.mobile.changePage("#loginPage");
},
onHideLogin : function() {
WL.Logger.debug("Inside auth.js.onHideLogin");
$.mobile.changePage("#page3");
}
};
}();
就像我提到的，第一次登录失败，它只是重新加载登录表单，我可以在 JS 控制台中看到上面的堆栈跟踪，但第二次它工作正常。我想知道第一次尝试时是否没有正确初始化某些东西，但第二次就可以了。谁能提出什么问题？
这些是我正在使用的页面元素：
<div data-role="page" id="page3">
<div data-theme="a" data-role="header">
<h3>Autenticated Page - Page3</h3>
</div>
<div data-role="content">
<h3>You are logged in -Page3</h3>
<a href="#page1">Go to page1</a>
</div>
<div data-theme="a" data-role="footer">
<input type="button" value="Logout"
onclick="WL.Client.logout('SampleAppRealm', {onSuccess: WL.Client.reloadApp});" />
</div>
</div>
<div data-role="page" id="loginPage">
