It is a modern, lightweight, cross-language, cross-platform, object-oriented, high performance, remote dynamic communication middleware. It is not only easy to use, but powerful. You just need a little time to learn, then you can use it to easily construct cross language cross platform distributed application system.

You don't need use the javascript source files. You only need include hprose.js in your html.
The file FlashHttpRequest.swf you can put it on anywhere, and then specify its load path by setting the flashpath attribute in the script tag. If you omit this attribute, the default path is current path.
If an error occurred on the server, or your service function/method throw an exception, it will be sent to the client. You need to pass an error callback function after succuss callback function to receive it. If you omit this callback function, the client will ignore the exception, like never happened.
For example:
<html>
<head>
<script type="text/javascript" src="hprose.js" flashpath="/"></script>
</head>
<body>
<script type="text/javascript">
var client = hprose.Client.create("http://www.hprose.com/example/", ["hello"]);
client.hello("World!")
.then(function(result) {
alert(result);
}, function(err) {
alert(err);
});
</script>
</body>
