Re: Struts and WebSphere
An alternate approach that worked for me: Add the web folder to the struts-example application classpath: C:\WebSphere\AppServer\hosts\default_host\struts-example\web When I did this, the struts-example app worked flawlessly. That might be a little simpler config than maintaining two separate WEB-INF folders, especially when updating a deployment. I like your idea of putting the DTDs in the systemwide classpath.

I was using an older version of struts.jar on that machine. I have the revised instructions at work, but the short of it is that the original article was right about adding the XML files to servlets\WEB-INF and the TLD files to web\WEB-INF. I would still make the argument that putting the DTDs in c:\websphere\appserver\classes is a good thing, since it can be done once system-wide *and* it solved my problems where the SYSTEM DTDs were not being registered properly.

Possiblility Answer to: html form widgets not appearing
It sounds like you have a classpath problem. I bet you either have a
system classpath (ie a classpath set in your
settings/controlpanel/system/advanced/environmentvariables assuming it
is a pc) which conflicts with the classpath you start up when you run your
server. Either way it seems that it cant find your file in the classpath to
load. Try to loop through and print to the console all of your system
variables at the point after you start up your server. (cut and paste class
below)
What you are looking for is the following system properties:
java.class.path
user.dir
Put your properties in the directory that indicates your user.dir. If it
works than your problem is your classpath.
import java.util.*;
public class DisplayEnvironment{
public static void main(String[] args){
new DisplayEnvironment();
}
public DisplayEnvironment(){
System.out.println();
displaySystemProperties();
System.out.println();
displayWeblogicProperties();
System.out.println();
}
private void displaySystemProperties(){
Properties p = System.getProperties();
Set set = p.keySet();
Object[] o = set.toArray();
List l = Arrays.asList(o);
Collections.sort(l);
Iterator i = l.iterator();
while(i.hasNext()){
String s = (String)i.next();
System.out.println(s + + p.getProperty(s));
System.out.println();
}//while
}//method
private void displayWeblogicProperties(){
}
}

The app server is the container for the servlet, so all of servlet code is
being
done by the app server, therefore if something is implemented wrong like
getServletContext() or something, than you will have a problem. Weblogic
has
all kinds of bugs like this.

RE: Reducing the burden on ActionServlet.
Title: Reducing the burden on ActionServlet. No - you have ONLY ONE instance for the ActionServlet. The user requests are just different threads that simultaneously call methods of the instance of that servlet. I think this is not related to Struts but to Java Servlet Specification - the Application Server creates only one instance of each servlet and calls it's service() method on request.

Re: switch from http to https
When I put Eric's code at the bottom of a secure logon action String url = mapping.findForward(success).getPath(); ActionForward actionForward = new ActionForward(url,true); return (actionForward); and the success forward is hardcoded with an absolute URL (http://mysite.com/myapp/), it goes to standard mode, but I get a warning from the browser. Obviously, the warning would generate some questions. Do I need some type of bridge page to do the redirect in the browser? -- Ted Husted, Husted dot Com, Fairport NY USA. -- Custom Software ~ Technical Services. -- Tel 716 737-3463. -- http://www.husted.com/about/struts/
Re: Possiblility Answer to: html form widgets not appearing
It shouldn't be a class path problem because it is trying to load the resource
within the web app, which should never be in the class path to begin with. It
is more likely a bug with the app server.
