I believe the USR AGENT is passed in the request header. You should,
therefor be able to easily get a handle on it using your Action object.
To enumerate through all header names available:
java.util.Enumeration e = request.getHeaderNames();
while(e.hasMoreElements()) {
String name = (String) e.nextElement();
String.value = request.getHeader(name);
System.out,println("ELEMENT = " + name + ", VALUE = " + value);
}
I think the user agent header name is just "User-Agent". Try that.

Subject: Screen Flow based on UserAgent in Struts
Hi,
Is there a way to config Struts to forward a different
jsp based on the User Agent of the HTTP Request? I
would like to use the User Agent to identify the
client type (e.g. where desktop or a mobile phone) and
send out either HTML content or WML content.
I come up this idea, I am wondering if there are
better solutions:
Have a different forward name, different path for each
device type:
For example, in struts-config.xml
<action path="/logoff"
type="org.apache.struts.webapp.example.LogoffAction">
<forward name="successHTML"
path="/indexHTML.jsp"/>
<forward name="successWML"
path="/indexWML.jsp"/>
</action>
And in the perform method of my action code, I have
something like:
if user agent is desktop
return (mapping.findForward("successHTML"));
else
return ((mapping.findForward("successWML"));
Thanks for any ideas.
Sam
