Hi,
I was curious if I could make my webservice work with firefox client
webservice functionality. (i got it to work with webservice.htc)

I am able to get firefox to see my serverside web service methods
(instantiate a proxy and alert proxy.MyMethod to tell its a valid
function), but when I submit to them, I either get, "Cannot convert
javascript arg 0" or "not enough arguments" javascript errors. I am
thinking that perhaps firefox does not understand auto generated WSDL.
I do not have much experience with WSDL and so perhaps someone has
attempted such feat....

FireFoxTest.aspx
<script>
var proxy = null;
var wsdl_uri = "http://localhost/webtesting/service.xml";
function run (aValue1, aValue2)
{
if (!proxy) {

var listener = {
onLoad: function (aProxy)
{
proxy = aProxy;
proxy.setListener(listener);
requestTranslation(aValue1, aValue2);
},
onError: function (aError)
{
alert(aError);
},

MyMathCallback : function (val)
{
alert('inside callback');
alert(val);
}
};

createProxy(listener);

}
else {
requestTranslation(aValue1, aValue2);
}
}
function createProxy(aCreationListener)
{
try {
var factory = new WebServiceProxyFactory();

factory.createProxyAsync(wsdl_uri, "MyMathSoap", "", true,
aCreationListener);

}
catch (ex) {
alert(ex);
}
}
function requestTranslation (value1, value2)
{
if (proxy) {
alert(proxy.Add);
proxy.Add();
}
else {
alert("Error: Proxy set up not complete!");
}
}
</script>

Hi,

I'm interested in working on this. Can you post your whole HTML file? I
don't see below where you put the reference to webservice.htc. I put it in
a div tag that has an onresult attribute when working with IE. Thanks.
Ken.
 
Hi, thanks for replying.

That was a complete call actually. firefox does not need a registration
with a div like msie does and it has native support for webservices
which means no .htc file is needed. its support is actually superior to
that of msie, because all you do is instantiate a proxy and call it as
if the webservice was a local object.

here is an example of a working firefox webservice:
http://www.mozilla.org/projects/webservices/examples/babelfish-wsdl/inde
x.html

just look at the javascript include.

the sample i posted gets to the point of seeing the service methods. it
just seems to give weird errors when those methods are actually called
(see error messages included in original post).

thank you!

Hi,

Okay I took a look and I'm getting the same result as you. It appears that
the problem revolves around Firefox's inability to conform to the standards
set forth by the W3C. Not surprising since they still have a handful of
security and SSL standards open in Bugzilla. Anyways, to get this to work
get rid of all your <s: tags, the ones that define elements and complex
types. Then in your <message tags remove the <part tags that rely on the <s
tags and define your arguments there instead. Basically you need to model
this:

http://www.xmethods.net/sd/2001/BabelFishService.wsdl

Then you should be all set. Good luck! Ken.
