Hi Geert (and all)
Is there a walkthru for the RIFE "helloworld"
application that is "end-to-end" complete, for
beginners?
I think this would be invaluable as a "quickstart" to
understanding the framework for RIFE newbies...like
myself.
When I tried following the partial "helloworld"
walkthru in the "Installing RIFE"(LiveGuide)
instructions, I was bummed to find that it did not
"walk" all the way thru to executing the application
in the browser.
My experience with trying new tools/frameworks/etc is
that most time is spent figuring out how to get a demo
application just to work the first time.
--And, it seems the success/failure rate is typically
a function of the completeness of a given "demo"
tutorial.
In any case, not surprisingly, my attempt at
re-creating the helloworld app failed. waaaah!....
I am running in Tomcat 5.5.1.6 on port 8084. (I
downloaded a fresh copy of same)
--Would this pose an issue?
I named the project folder/context: "rifeapp"
and
I used the following URL to run the app in my
browser(IE) is: http://localhost:8084/rifeapp/
--Is this be incorrect?
My "rifeapp" application's (deployed) file structure
is as follows:
[rifeapp]
|
+---[META-INF]
|
+---[WEB-INF]
|
+---[classes]
| |
| +---[helloworld]
| | |
| | +---HelloWorld.class
| |
| +---[rep]
| | |
| | +---participants.xml
| |
| +---[sites]
| | |
| | +---helloworld.xml
| |
| +---[templates]
| |
| +---[helloworld]
| |
| +---helloworld.html
|
+---[lib]
| |
| +---rife-1.4.-jdk15.jar
|
+---web.xml
---Is there something missing from what you can see in
the above structure?
My "rifeapp" key files are as follows:
***HelloWorld.java***
package helloworld;
import com.uwyn.rife.engine.Element;
import com.uwyn.rife.template.Template;
public class HelloWorld extends Element
{
public void processElement()
{
Template template =
getHtmlTemplate("helloworld");
template.setValue("hello", "Hello world.");
print(template);
}
}
***participants.xml***
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE rep SYSTEM "/dtd/rep.dtd">
<rep>
<participant
param="sites/helloworld.xml">ParticipantSite</participant>
</rep>
***helloworld.xml***
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE site SYSTEM "/dtd/site.dtd">
<site>
<element id="HelloWorld"
implementation="helloworld.HelloWorld" url="/home"/>
</site>
--NOTE: what does 'url="/home"' do???...
***helloworld.html***
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml";
xml:lang="en" lang="en">
<head>
<title>${v hello/}</title>

<body>${v hello/}</body>
</html>
***web.xml***
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee

---Can you see any errors/etc in the code/xml/schema
above?
