Hi Hynek,
basically, you should create a request like this:
http://localhost:8080/rest?submission=call
but then in post.
I don't know which library you're using, but this is what you'd do
with RIFE's HttpUtils (yes, by just using the RIFE jar in another
application, not necessarily a webapp):
HttpUtils.Page page = new HttpUtils.Request("http://localhost:8080/
rest")
.postParam("submission", "call")
.retrieve();
System.out.println(page.getContent());
However, note that this code is not intended to run on a production
system. I use it and I know that if network connections fails that
there's not much in there to do any fault handling and such.
This might get you started.
Take care,
Geert

Hi,
after I finally ditched SOAP (of course, Google had to imitate
me ;)) I
decided to use simple webservices using HTTP POST.
Frankly, the client should simply POST the command using HTTP and
receive an answer.
As I understand it, I'll have to simulate a submission using the
client. My first simple tries were in vain so I used a sniffer to look
at the traffic for the number guess game and I'm pretty confused now:
submission=performGuess&submissioncontext=VERY_LONG_STRING&guess=4
Is this submission context really necessary? How can I simulate
him? Is
there some easier way I'm missing?
Ideally, the Element should just look something like this:
--8<---------------cut here---------------start------------->8---
public class Rest extends Element {
public void processElement() {
if (hasSubmission()) {
Foo.process(getSubmission());
}
}
--8<---------------cut here---------------end--------------->8---
What I've tried:
--8<---------------cut here---------------start------------->8---
<element id="REST" url="/rest" implementation="my.impl">
<submission name="call">
<param name="script" />
</submission>
</element>
--8<---------------cut here---------------end--------------->8---
and:
--8<---------------cut here---------------start------------->8---
public class Rest extends Element {
public void processElement() {
System.out.println("inside");
if (hasSubmission("call")) {
System.out.println("submission");
}
}
public void doCall() {
System.out.println("foo");
}
}
--8<---------------cut here---------------end--------------->8---
Then I try to call it using:
--8<---------------cut here---------------start------------->8---
PostMethod post = new PostMethod("http://localhost:8080/rest";);
RequestEntity ent = new StringRequestEntity
("submission=call&script=bar", "application/x-www-url-encoded",
"utf8");
post.setRequestEntity(ent);
HttpClient httpclient = new HttpClient();
int result = httpclient.executeMethod(post);
System.out.println("Response status code: " + result);
--8<---------------cut here---------------end--------------->8---
I get a 200 back, `inside' is printed but `submission and `foo' not.
I'm pretty sure I'm missing something obvious...any hints?
TIA,
