<action name="action1"
                        class="jp.co.fujixerox.eappli.printapp.struts.PostLauncherAction">
                        <result name="error" type="chain">
                                <param name="actionName">action2</param>
                                <param name="name">close</param>
                        </result>
</action>
<action name="action2"
                        class="jp.co.fujixerox.eappli.printapp.struts.PostLauncherAction">
                        <result name="success">/jsp/showResult/success.jsp</result>
</action>
So at controller of action2, I use request.getParameters("name")=null;

hm... but the "name" parameter from the "action1" isn't a request
parameter, it will be applied only to the "action1".

I would use rather the "actionRedirect" result instead of the "chain" result

Using action chaining isn't recommended, instead it's better to
re-think why do you want to do it and use some other result type:
https://struts.apache.org/docs/action-chaining.html

but if you want to do it you must define exactly the same
getters/setters in both actions to pass static params, and you must
define this on action level not on result level, see the example:
https://github.com/apache/struts-examples/tree/master/action-chaining

Dao Cong Hung (FSU17.BU68)
Thanks you, So if I convert struts1 to Struts2 in file config.xml.
<forward name="error"      path="/ action2.do?name=close " />  it keep request at the action2
So with struts2 type result  the same forward except "chain"

Nope, there is no "forward to action" result in Struts2, the closest
approach is to use "chain" but it isn't recommended. Since you're
migrating the project maybe it would be a good idea to rethink some
patterns, which worked well in Struts1 but not in Struts2 - Struts2 is
a totally different framework and uses different patterns.
