can a non struts application be called from inside stuts application.
i have a shopping cart struts application, when update button of a jsp is
clicked, some action is performed and after the successful excution of that
action, a servlet which takes certain parameters should be called from the
action class.
The servlets which i am talking about are non-struts based and are already
implemented, and it would take much time to redo those using struts, so i am
wondering if there is any way to reuse those and call those servlets from
actions class.

Try it yourself.... no JSP's. No struts, and basic CRUD operations on an
address book.
Now today, you would probably be smart. You would have a CRUD servlet for
the "actions", that would redirect to a servlet for generating HTML. That's
4 serlvets handling CRUD, one servlet to generate the add/edit form page,
one servlet to generate the list address page.
And no, you don't get to use jakarta's ECS either!!! Nope. Not at all..
you can however drool over it :)
out.println( "<html>");
out.println( "<head>");
out.println( "<title>THis is the title of my page.</title>");
<out.println( "</head>");
Or:
out.println( "<html>"
+"<head>"
+" <title>This is the title of my page.</title>");
+"</head>");

Well, you can't call a servlet from an Action with a Java method call
but you can easily forward the request to the servlet from the action. I
suggest creating a local or global forward element for the servlet.
<action path="/MyAction"
type="com.foo.MyAction">
<forward name="LegacyServlet" path="/path/to/old/servlet"/>
</action>
Then in the MyAction.execute() ...
// business logic
//...
// now forward to old servlet
return mapping.findForward("LegacyServlet");
}

Well, you can't call a servlet from an Action with a Java method call
but you can easily forward the request to the servlet from the action. I
suggest creating a local or global forward element for the servlet.
<action path="/MyAction"
type="com.foo.MyAction">
<forward name="LegacyServlet" path="/path/to/old/servlet"/>
</action>
Then in the MyAction.execute() ...
// business logic
//...
// now forward to old servlet
return mapping.findForward("LegacyServlet");
