Q : Calling an action via a java URL ?
hi fellow programmers
im trying to call a struts action via http in a java program.
Something like URL (Action to call)
http://localhost:8443/printHelloWorld.do
this returns a blank page with the text "Hello World"
I want to read this input from a java program using something like
URL u = new URL(notificationServiceURL);
URLConnection uc = u.openConnection();
uc.setDoOutput(true);
uc.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded");
PrintWriter pw = new PrintWriter(uc.getOutputStream());
pw.close();
BufferedReader in = new BufferedReader(new InputStreamReader(
uc.getInputStream()));
String res = in.readLine()
.trim();
in.close();
But i keep getting some errors.
Has someone tried this before? with parameters, properties, etc etc?
Thanks a lot

Re: Really Dynamic Forms
DynaForms aren't as dynamic as there name suggest, at least not until
you start using indexed properties.If the case of forms you'll still be
wanting to use struts html tags, as jstl doesn't cover this yet until
java servers faces is released.
For most cases nesting beans works
//in struts config
I'm using arraylist rather than User[] .. I still need to find out
whether there's an advantage.
..
//in the bean
public class User {
String name;
getName() {
return name;
}
setName(String str) {
this.name = str;
}
}
..
//in the action
User user = new User();
user.setName("Brian Blessed");
User anotherUser = new User();
anotherUser.setName("Brian Clough");
ArrayList list = new ArrayList();
list.add(user);
list.add(anotherUser);
theForm.set("user",list);
..
...
ArrayList userList = (ArrayList) theForm.get("user");
for(int i = 0;i < userList.size();i++) {
User user = (User) userList.get(i);
System.out.println(user.getName());
}
..

Subject: Really Dynamic Forms
Hello,
So I have a problem, and I just can't get out of the box to look at it
anymore so I am writing you all:
I have a user registration page and action i am writing. User can
have a
variable number of properties with different names that need to be
filled
in. User also has some properties that always need to be filled in.
I am not sure how to do this using struts forms of any kind. It
seems to
me
that I need to define at least the names of the properties in advance,
when
that will be changing (I know the client will be adding and removing
properties in the future so I can't hardcode them).
Right now I am using a regular form, I have my fixed properties
hardcoded,
and variable ones are preloaded in a map in the setup action and I
iterate
over them to display them. Then in the action I retrieve them.
This is fine until I want to validate something, and I really like
struts
forms validation, so i'd like to use them if possible.
To summarize:
I have a map of properties, as well as some regular properties.
I want to use a struts form to retrieve the data.
I don't know how to do it so the names are dynamic.
Regards,
Denis

Question about properties in the struts configuration file
Hi, I can see that for each action, is possible to define some properties via the property element. Now, I cannot see any method in the ActionConfig file which returns those properties.

RE: Validator, DynaForms, and Collections
One work around that doesn't require you to place your Collection in the session is to make the input attribute value of your action element equal to your "setup" action for the page. Another thing to think about is if your Collections are composed of static data, place them in the ServletContext when your web application starts up and then a single copy is available to all users. robert > -Original Message- > From: Joe @ Team345 [mailto:[EMAIL PROTECTED] > Sent: Saturday, September 13, 2003 9:26 AM > To: Struts Users Mailing List > Subject: Re: Validator, DynaForms, and Collections > > > Thanks David.

Re: EL Question
Hi Denis,
have you got EL working at all at any point, or is it just this page? I
can't say I've seen that error before but it looks like a configuration
problem.
By the way, why are you populating your formfields this way, and not
letting struts take care of it for you? Are you deliberately using a
second action form for this page?
