You could create a log out link to Liferay's internal logout functionality like this one in your JSP:

<pre><code>&lt;%@page import="com.liferay.portal.util.PortalUtil"%&gt;
.
.
&lt;a href="&lt;%= PortalUtil.getPortalURL(request) %&gt;/c/portal/logout"&gt;Log Out&lt;/a&gt;
</code></pre>

blocks|key|2346766|text|经过2-3天的调查，我实现了使用ajax调用登录和注销。要注销它并不像调用session.invalidate()那么简单，但只需要配置一点即可。我将写下我是如何做到这一点的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2346767|首先编辑您的portal-ext.properties并添加以下行:+session.enable.phishing.protection=false|2346768|然后，在所有portlet中，您必须将private-session-attribute设置为false。排序很重要，所以我将向您展示我的矿：|2346769|<portlet>
++++<portlet-name>home</portlet-name>
++++<icon>/icon.png</icon>
++++<instanceable>false</instanceable>
++++<private-session-attributes>false</private-session-attributes>
++++<header-portlet-css>/css/main.css</header-portlet-css>
++++<footer-portlet-javascript>/js/home.js</footer-portlet-javascript>
++++<css-class-wrapper>home-portlet</css-class-wrapper>
</portlet>|code-block|syntax|javascript|2346770|一旦这样做了，剩下的事情就很简单了。对于登录：|2346771|public+static+void+login(ResourceRequest+request,ResourceResponse+response,+String+liferayUser,+String+liferayPassword)+throws+Exception{
++++MethodKey+key+=+new+MethodKey("com.liferay.portlet.login.util.LoginUtil",+"login",+HttpServletRequest.class,+HttpServletResponse.class,+String.class,+String.class,+boolean.class,+String.class);
++++PortalClassInvoker.invoke(false,+key,+new+Object[]+{+PortalUtil.getHttpServletRequest(request),+PortalUtil.getHttpServletResponse(response),+liferayUser,+liferayPassword,+false,+null});+++++++
}|2346772|对于注销：|2346773|public+static+void+logout(ResourceRequest+resourceRequest)+throws+Exception{
++++HttpServletRequest+request+=+PortalUtil.getHttpServletRequest(resourceRequest);+
++++request.getSession().invalidate();
}|2346774|我使用ResourceRequest是因为我在做Ajax调用。唯一的“问题”是，如果您已经登录，并且想要注销并使用另一个用户登录，那么您必须执行两个ajax调用(第二个调用从第一个调用返回)。|2346775|entityMap^0|0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|X|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|Y|8|@]|9|@]|A|$]]|$1|F|3|G|5|H|7|Z|8|@]|9|@]|A|$I|J]]|$1|K|3|L|5|6|7|10|8|@]|9|@]|A|$]]|$1|M|3|N|5|H|7|11|8|@]|9|@]|A|$I|J]]|$1|O|3|P|5|6|7|12|8|@]|9|@]|A|$]]|$1|Q|3|R|5|H|7|13|8|@]|9|@]|A|$I|J]]|$1|S|3|T|5|6|7|14|8|@]|9|@]|A|$]]|$1|U|3|-4|5|6|7|15|8|@]|9|@]|A|$]]]|V|$]]

After 2-3 days of investigating I achieved logging in and out with ajax calls. To logout it is not as simple as calling the session.invalidate() but there is only a little more to configure. I will write how I achieved this:

First edit your portal-ext.properties and add this line:
session.enable.phishing.protection=false

Then in ALL of your portlets you have to set the private-session-attributes to false. The ordering is important so I'll show you mines:

<pre><code>&lt;portlet&gt;
 &lt;portlet-name&gt;home&lt;/portlet-name&gt;
 &lt;icon&gt;/icon.png&lt;/icon&gt;
 &lt;instanceable&gt;false&lt;/instanceable&gt;
 &lt;private-session-attributes&gt;false&lt;/private-session-attributes&gt;
 &lt;header-portlet-css&gt;/css/main.css&lt;/header-portlet-css&gt;
 &lt;footer-portlet-javascript&gt;/js/home.js&lt;/footer-portlet-javascript&gt;
 &lt;css-class-wrapper&gt;home-portlet&lt;/css-class-wrapper&gt;
&lt;/portlet&gt;
</code></pre>

Once did this the rest is pretty simple. For log in:

<pre><code>public static void login(ResourceRequest request,ResourceResponse response, String liferayUser, String liferayPassword) throws Exception{
 MethodKey key = new MethodKey("com.liferay.portlet.login.util.LoginUtil", "login", HttpServletRequest.class, HttpServletResponse.class, String.class, String.class, boolean.class, String.class);
 PortalClassInvoker.invoke(false, key, new Object[] { PortalUtil.getHttpServletRequest(request), PortalUtil.getHttpServletResponse(response), liferayUser, liferayPassword, false, null}); 
}
</code></pre>

And for log out:

<pre><code>public static void logout(ResourceRequest resourceRequest) throws Exception{
 HttpServletRequest request = PortalUtil.getHttpServletRequest(resourceRequest); 
 request.getSession().invalidate();
}
</code></pre>

I used ResourceRequest because i was doing Ajax calls. The only "problem" is that if you are logged in and want to logout &amp; login with another user you have to do 2 ajax calls (the second one once returned from the first one).

Being quite new to liferay/portal/portlet development you run into problems daily . Now i'm trying to for a logout from a portlet but have not found a way to accomplish that. How are you supposed to do that? Should I try to send some kind of logout event or something? Greping around in the liferay sources i have found a LogoutAction.java that seems promising but how do one trigger that?
