Hi,
I think the best solution is to implement SessionAware interface and
setSession() method, then you will either add or remove values from
map. Like below:
public class IndexAction implements Action, SessionAware {
private Map<String,Object> session;
public void setSession(Map<String,Object> session) {
this.session = session;
}
public String execute() {
session.put("key", "Some Value");
return SUCCESS;
}
public String doCheck() {
return SUCCESS;
}
}
snippet from struts.xml
<package name="myPackage" extends="struts-default">
<action name="index" class="pl.org.lenart.s2demo.IndexAction">
<result>/jsp/index.jsp</result>
</action>
<action name="check" class="pl.org.lenart.s2demo.IndexAction"
method="doCheck">
<result>/jsp/index.jsp</result>
</action>
</package>
index.jsp to test session value
<html xmlns="http://www.w3.org/1999/xhtml"; xml:lang="en" lang="en">
<head>
<title>Index</title>
<s:head />
</head>
<body>
<s:property value="#session.key"/>
</body>
</html>
Go to http://localhost:8080/<context>/index.action and you will see
the value from session, then go to
http://localhost:8080/<context>/check.action and once again you will
see the same value. Go to some other page in Internet and then come
back to http://localhost:8080/<context>/check.action, once again you
will see the same ;-)
Your action is free from hard coded dependency to ActionContext. I
check this and it's working, I'm using Struts 2.1.3-SNAPSHOT
