How to call/access 2 different actions at the same time from JSP page in Struts 2?

I'm developing a Struts 2 application. In order to remove duplicated code, I want to have access to an Action (let's call it A) in 2 different JSP pages (let's say page_1.jsp and page_2.jsp). So far, so good. The problem is that in each of these 2 JSP pages, I also need to have simultaneous access to an additional action: B and C, respectively.

To summarize: page_1.jsp needs access to Actions A and B, while page_2.jsp needs access to Actions A and C. How would I get that? As far as I know, using type = "redirectAction" in struts.xml won't work, because it only redirects to the action, so the JSP page will only have access to the last action called.

Example:

<action name="A" class="package.action.A" method="execute">
    <result name="success" type="redirectAction">B</result>
</action>

<action name="B" class="package.action.B" method="execute">
    <result name="success">page_1.jsp</result>
</action>

As far as I know, in the example above page_1.jsp will only have access to action B, right?

EDIT:

In fact, class A is named CreateArchitecturesAction - I need to access it on actions B and C, in order to populate a similar <s:radio> tag on both. The code is as simple as this:

public class CreateArchitecturesAction extends ActionSupport
{
    private List<String> architectures;

    private static final String intel32 = "Intel 32 Bit", intel64 = "Intel 64 Bit";

    public String execute()
    {
        architectures = new ArrayList<String>();
        architectures.add(intel32);
        architectures.add(intel64);

        return SUCCESS;
    }

    public List<String> getArchitectures()
    {
        return architectures;
    }

    public String getDefaultArchitectureValue()
    {
        return intel32;
    }
}

Only one action you have access from JSP, however you can have access to any scope available in JSP after the page is dispatched. So this flow 

<action name="A" class="package.action.A" method="execute">
    <result name="success" type="dispatcher">B</result>
</action>

<action name="B" class="package.action.B" method="execute">
    <result name="success">page_1.jsp</result>
</action>

You can have access to action B if you change the scope of the action to request scoped.
