[英]Basic JSF with Session doesn't work in glassfish
我想在集群環境中測試JSF 2的會話和應用程序范圍的Bean的會話復制,目前正在嘗試使用glassfish。 為此,我創建了一個簡單的應用程序,然后將其首先部署到服務器以驗證其是否正常工作(不是)。
這是我到目前為止所做的:
取決於web.xml中的javax.faces.STATE_SAVING_METHOD,結果為:
要創建該應用程序,我執行了以下操作:
會話作用域bean(應用程序作用域類似):
@ManagedBean(name = "sessbean")
@SessionScoped
public class MySessionScopeBean implements Serializable{
private static final long serialVersionUID = -4733271400646173098L;
private String value = "default session data";
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
}
index.xhtml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html">
<h:head>
<title>JSF 2.0 Hello World</title>
</h:head>
<h:body>
<h3>JSF 2.0 Hello World Example - hello.xhtml</h3>
<h:outputText value="Session id: #{sessionScope['id']}" />
<h:form>
<h:panelGroup>
<h:outputText value="Session Variable:"/>
<br/>
<h:inputText value="#{sessbean.value}"/>
</h:panelGroup>
<h:commandButton value="submit"/>
</h:form>
<h:form>
<h:panelGroup>
<h:outputText value="Application Variable:"/>
<br/>
<h:inputText value="#{appbean.value}"/>
</h:panelGroup>
<h:commandButton value="submit"/>
</h:form>
</h:body>
</html>
因此,這個非常基本的示例不起作用。 有什么建議么?
另外,會話ID不會顯示在#{sessionScope ['id']}中,不知道這是否是這樣做的方法。
通過刪除(生成的)web.xml文件的一部分使它正常工作。 工作文件如下所示:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

我剝離的內容(不知道是哪個部分導致了故障):
<context-param>
<param-name>javax.servlet.jsp.jstl.fmt.localizationContext</param-name>
<param-value>resources.application</param-value>
</context-param>
<context-param>
<description>State saving method: 'client' or 'server' (=default). See JSF Specification 2.5.2</description>

<param-value>client</param-value>
</context-param>
<context-param>
<description>
This parameter tells MyFaces if javascript code should be allowed in
the rendered HTML output.
If javascript is allowed, command_link anchors will have javascript code
that submits the corresponding form.
If javascript is not allowed, the state saving info and nested parameters
will be added as url parameters.
Default is 'true'</description>
<param-name>org.apache.myfaces.ALLOW_JAVASCRIPT</param-name>
<param-value>true</param-value>
</context-param>
<context-param>
<description>
If true, rendered HTML code will be formatted, so that it is 'human-readable'
i.e. additional line separators and whitespace will be written, that do not
influence the HTML code.
Default is 'true'</description>
<param-name>org.apache.myfaces.PRETTY_HTML</param-name>
<param-value>true</param-value>
</context-param>

<param-name>org.apache.myfaces.DETECT_JAVASCRIPT</param-name>
<param-value>false</param-value>
</context-param>
<context-param>
<description>
If true, a javascript function will be rendered that is able to restore the
former vertical scroll on every request. Convenient feature if you have pages
with long lists and you do not want the browser page to always jump to the top
if you trigger a link or button action that stays on the same page.
Default is 'false'
