Hi,

I tried the xml-rpc.xul testfile on mozilla 0.9.1 loaded from a
chrome:// url. When i press either the "Async" or the "Sync" button, the
function breaks and mozilla dumps an exception on the console:

Document chrome://test/content/xml-rpc.xul loaded successfully
Call Async
************************************************************
* Call to xpconnect wrapped JSObject produced this error: *
[Exception... "Could not convert JavaScript argument (NULL value
cannot be used for a C++ reference type) arg 0
[nsISupports.QueryInterface]" nsresult: "0x8057000b
(NS_ERROR_XPC_BAD_CONVERT_JS_NULL_REF)" location: "JS frame ::
/var/tmp/mozilla/dist/bin/components/nsXmlRpcClient.js :: anonymous ::
line 235" data:no]
************************************************************

JavaScript error:
line 0: uncaught exception: [Exception... "Could not convert
JavaScript argument (NULL value cannot be used for a C++ reference
type) arg 0 [nsISupports.QueryInterface]" nsresult: "0x8057000b

/var/tmp/mozilla/dist/bin/components/nsXmlRpcClient.js :: anonymous ::
line 235" data: no]

Anyone have a suggetion? it's an error on my setup on in mozilla?

thanks in advance

ciao, Alberto

XML-RPC has bitrotted, someone would have to bring it up to date.

I'm trying to patch up the code. Anyone know what

var postStream = handler.NewPostDataStream(false, '\r\n' + request,
handler.ENCODE_NORMAL);

means? I had a look at nsIHttpProtocolHandler, and I'm not sure what
the replacement function is called.

The exception you're getting is because the interface was renamed from
nsIHTTPChannel to nsIHttpChannel. There are lots of other fun bugs
though...

Hi,
The following example works fine with Mozilla 0.9.2 and Zope 2.4.0
I spent lot of time to try the xul example of XML-RPC with no success.
So I decide to test XMLHTTPRequest example
(mozilla\extensions\xmlextras\tests\post.html) with some modification.
I am a XUL/Mozilla newbie and so forgive me for the style.

The trouble is that I do not know how to run
mozilla\extensions\xmlextras\tests\syncpost.html ???

<html>
<body>
<h1>Posting test</h1>
<script>
const WSTRING_CONTRACTID = "@mozilla.org/supports-wstring;1";

// bypass file security default :

netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead");
netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");

var p = new XMLHttpRequest();

function myfunc()
{
var str;
str = p.responseText;
alert(str);
document.write (str);
// alert(p.getAllResponseHeaders());
}

p.onload = myfunc;

p.open("POST", "http://localhost:8080");

var mystr =
Components.classes[WSTRING_CONTRACTID].createInstance(Components.interfaces.
nsISupportsWString);

mystr.data = "<?xml
version=\"1.0\"?><methodCall><methodName>testMethod</methodName>";
mystr.data = mystr.data + "<params>";
mystr.data = mystr.data + "<param><value><struct>";
mystr.data = mystr.data +
"<member><name>name</name><value>myName</value></member>";
mystr.data = mystr.data +
"<member><name>age</name><value><i4>42</i4></value></member>";
mystr.data = mystr.data + "</struct></value></param>";
mystr.data = mystr.data + "</params></methodCall>";
p.send(mystr);

</script>
</body>
</html>

I don't understand. If post.html works for you, syncpost.html should
work equally well. To test, you just open the file in your browser
(well, you need to have the echo.cgi script on some server you control
and change the URL in post and syncpost to point to it - which you must
have done since you say post was working).

I almost have this working, but I'm blocked by
http://bugzilla.mozilla.org/show_bug.cgi?id=100172

There were lots of changes in API that were not kept up with.
