Hi all,

I probably should have sent out this mail much earlier.
Unfortunately I just don't have enough free time to work on jsolait
anymore. I have not been able to do any work on it for quite some time
and don't see me being able to do any in the near future :(
Sorry!

So, if anyone fancies taking over the project, give me a shout.

Hi,
I'm jsolait's XMLRPC to implement a manager, but the
request issued to the HTTP server contains only the HTTP headers.
Is this normal ?

Code:
<script type="text/javascript">listTests();</script>
function listTests()
{
var xmlrpc=null;
try{
       xmlrpc = imprt("xmlrpc");
}catch(e){
       alert(e);
       throw "Importing of xmlrpc module failed.";
}
       var methods=["listTests"];
       try{
             //var service = new xmlrpc.ServiceProxy( server, methods);
             //var response = service.listTests();
             var service = new xmlrpc.XMLRPCMethod( server, "listTests");
             var response = service();

             document.write("Common Tests:<br>");
             document.write("<select name='sut_tests'
multiple='multiple' size='5'>");
             for ( test=0;test<  response.length; test++)
             {
                   document.write('<option>' + response[test] +
'</option>');
             }
             document.write('</select>');
       }catch(e){
             var em;
             if(e.toTraceString){
                   em=e.toTraceString();
             }else{
                   em = e.message;
             }
             document.write( "Error trace: <br>" + em+"<br>");
       }
}

Yes you can.


Jan

I think I need some more info on that, maybe some code so I can
reproduce the problem.

There is no reason why the callback should not see the function.
e.g:

function foobar(a){
   print(a);
}

var ServiceProxy = imprt("jsonrpc").ServiceProxy
var serviceURL = "http://jsolait.net/services/test.jsonrpc";
var methods = ['echo'];

var service = new ServiceProxy(serviceURL, methods);
service.echo("hello", function(r,e){
   foobar(r)
})



works just fine when you run it in
http://jsolait.net/wiki/jsolaitLive

Hello,
i'm new to jsolait.

i've using it like a charm.
but i have problems with callbacks.

i use json rpc instead of xml rpc, but i think the case would be the
same.

the codes inside the callbacks function seems to be blind to other
methods created in the same script.
it can only calls javascript builtin methods or dom method only.

supposely there are function like this
function justAdd(a,b){
   return a+b;
}

the code inside callback function did not recognise this method.

i do this because i also use other dhtml enricher script such as dojo
toolkit and my own libraries with my code. and the callback function
cannot call methods from these libraries.

best regards,
Henry

Sorry, the build.js in the trunk does not work yet.
either just use the source or use the 2.0 version of jsolait.

I just downloaded the latest SVN and when I attempted to build I
received the following error:

CreateModuleFailed in [module 'jsolait' version: Rev.85]:
     Failed to create module [module '__main__' version: 0.0.0]

     number:-2146823281
     description:Object expected

Does anyone have any ideas?

I am trying to use the jsolait XML-RPC support to communicate with an
XML-RPC I have written.  The problem I'm running into is that my
Javascript and jsolait code are at:

    http://my.domain.com/somepage.html

but my XML-RPC server is accessible via:

    http://my.domain.com:8100/

jsolait (or perhaps the underlying XmlHttpRequest object) seems to
consider my.domain.com:8100 distinct from my.domain.com, and thus
off-limits.

I see that the XML-RPC tester at
http://jsolait.net/wiki/examples/xmlrpc/tester sends its XML-RPC
queries to http://jsolait.net/services/test.xmlrpc rather than to a
separate port from the main web browser.

Can anybody tell me how to set things up like this, so that my
original page and my server use the same domain (with no port number)?
  If it's relevant, I'm using Apache on FreeBSD.

Thanks,

Jeff Ondich

I getting RequestOpenFailed Opening of HTTP request failed when doing
a xmlrpc ServiceProxy call to a different host in Mozilla.

I've read about the cross-domain security issue and am bypassing it with
netscape.security.PrivilegeManager.enablePrivilege, for now.

This works from my server(localhost:9080/test.html) when the
url=http://jsolait.net/test.py.
But it fails when url=http://localhost:9080/echo.

The code is pretty simple and below.

Thanks for any help

try{
   if (navigator.appName=="Netscape"){
netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead");
   }
   var service = new xmlrpc.ServiceProxy(url, ['echo']);
   var asXml = service.echo(msg);
   result.value = asXml;
}catch(e){

   result.value='Error occured '+printException(e);
}

thanks for the fix, I'll put that into the code.

I tried your code to guess the position of jsolait (experimental)
and got nothing. It was because I had positioned some script-text
inserted directly into the html-head before the script-tag for jsolait.
That results in src=Null and in an error, leaving the loop.

I extended the code like below and all worked well:

     ///The location where jsolait is installed.
     mod.baseURI="./jsolait";

     try{// to guess the location where jsolait is installed
         var elems=document.getElementsByTagName('script');
         for(var i=0;i<elems.length;i++){
             var src=elems[i].getAttribute('src');

             if (src==undefined) continue;

             var idx=src.indexOf('jsolait.js');
             if(idx>0){
                 mod.baseURI=src.slice(0,idx-1);
                 break;
             }
         }
     }catch(e){

it looks like FF2 fixed the with-statement handling in JavaScript,
the issue described earlier does not occur anymore.

So, I am thinking of adding support for the following in jsolait:

e.g of a module source file

mod.foobar=function(...){

   ...
}

mod.test=function(...){

    foobar();
}


the magic is that 'mod.' is only used to define objects that can be
imported by other modules. Inside the module itself these objects will
look like local objects declared with 'var'. This should make things a
bit more comfortable to write.

I will do some further investigation if there are any issues using
this approach.

Comments are appreciated.

Hi, I am not sure this is the right place to ask.

I am using JSON-RPC-JAVA and wondering how I can Invoke method with
HTTPSession or request as parameters. In other words, how can I pass
HTTPSession as one of the parameter for a java method I like to invoke?

Thanks

Hey,

> var proxy = new xmlrpc.ServerProxy(...)
> rstl = proxy.getMethotName()

rslt is already converted, i.e.
the server response(xml data) was converted to a javascript object
by the proxy.
In your example rslt would be an Array containing a single item
the item is an Object containing with two properties, FData1 and
Fdata2. The properties have the values FVar1 and FVar2,
you could access them by

rslt[0].FData1
and
rslt[0].FData2
or
rslt[0]['FData1']

If you are working with jsolait2 or the experimental branch you can
use alert(repr(rslt)) to have a look at the rslt's code reprThis might
make things a bit easier if you are not sure what the object is that
is returend from the call.

Hello dear Jan.
Thank you for your answer. It has helped me.
But I have one more question. My server send me an XML-RPC answer, and
I use the DOM model for reception of parameters of the answer. For
example:
==
var proxy = new xmlrpc.ServerProxy(...)
rstl = proxy.getMethotName()

//and next:
xmlrpc.marshall(rstl);
//XML as string and next use DOM
==
May be JavaScript o Lait has functions for getting parameters from an
XML-RPS.
For example, I have this XML answer:
==
<methodResponse>
<params>
<param>
<value>
<array>
<data>
<value>
<struct>
<member>
<name>FData1</name>
<value>FVar1</value>
</member>
<member>
<name>FData2</name>
<value><int>FVar2</int></value>
</member>
</struct>
</value>
</data>
</array>
</value>
</param>
</params>
</methodResponse>
==
How can I get "FData1" and "FVar1" using jsolait?
Thank you!

one thing can be memory leaks.
you should be able to see that easyly by looking at the mem the
browser consumes and see if that increases over time.

I don't have links on hand but a google search for html memory leaks
and closures should pop up enough info. there is a neat tool for IE
called drip one can use to check for leaks.


the next thing could be that you have too many requests hanging.
e.g. if you initiate a request every 750ms no matter if prev.
req. have finished. This could leasd to a build up of unanswered
requests. Not sure though if that would have any effect.
When you do a request make sure to set the timeout for the next one
iisode the callback for the current one. this will make sure you only
have one open req.

Instead of polling every 750ms, you can use a hangign get.
i.e. unless something changes or a timeout has been reached the server
will just wait with answering the req. This will lower the number of
req. made to the server but may have other implications as the
connection stays open for quite some time depending on the timeout.


That's my initial thoughts

Jan

>   var rslt = xmlrpc.ServerProxy("http://server:1111", data);

that should be:

var proxy = new xmlrpc.ServerProxy(...)
rstl = proxy.getMethotName()


if that does not work, please put the error message in your post so
one can see whats going on.

Jan

Hello dear members of jsolait group.
I have a small experience  with jsolait.

Main question:
How I can make request to the server.
Request example:
==================
POST / HTTP/1.0
Host: http://server:1111
Content-Type: text/xml; charset=windows-1251
Content-Length: length

<?xml version="1.0" encoding="Windows-1251"?>
<methodCall>
		 <methodName>getMethotName</methodName>
		 <params></params>
</methodCall>

==================

My JavaScript code:
==================
try
{
   var xmlrpc = imprt("xmlrpc");
   var data = ["getMethotName"];
   var rslt = xmlrpc.ServerProxy("http://server:1111", data);
   alert(rslt);
}
catch(e)
{
     alert(e);
};
==================
But it's don't work.
Please help.

That should work.

I will have a look and make thwe changes in the trunk

Hi,

I simply went into the xmlrpc.js. I change "var handleResponse" to
"publ.handleResponse" and located all the calls to "handleResponse"
and changed it to "this.handleResponse".

Everything else seems to work. Is this the correct way to do what I
wanted to do? Are you planning to change this in the trunk?

handleResponse is declared with var and therefor enot visible outside
of the class.

it might be a good idea to handle have it part of the object so one
can do things like you describe.

Version 2.0 is great!  Now we can get subclasses to retain their
private variable correctly.  You can run the html below to see what I
mean.  Change the jsolait.js path if needed.

I tried using the handleResponse function from the XMLRPCMethod. But I
couldn't get it to work.

I have something like this:

function foo(url)
{
var liburl = imprt("urllib");
var xmlrpc = imprt("xmlrpc");

var resp = postURL(url);
var obj = new this.xmlrpc.XMLRPCMethod();

test.handleResponse(obj);
}

Are functions declared as "var" in the class not callable from outside
the function?

Hi,

I had to bypasss the XML RPC ServiceProxy and HTTP POST directly to a
server. The server returns an XMLRPC response. I want to use the
XMLRPC module to handle the response.

I tried using the handleResponse function from the XMLRPCMethod. But I
couldn't get it to work.

I have something like this:

function foo(url)
{
var liburl = imprt("urllib");
var xmlrpc = imprt("xmlrpc");

var resp = postURL(url);
var obj = new this.xmlrpc.XMLRPCMethod();

test.handleResponse(obj);
}

Are functions declared as "var" in the class not callable from outside
the function?

-Roy

Ah.

Another approach that I am considering is to uploat the file to the a
HTTP server and have that XML-RPC over to the XML-RPC server.

I already have to do a PHP proxy all my XML-RPC calls because Firefox
doesn't allow javascript to communicate with XML-RPC servers located
on the same host BUT different port number. So, passing the file to
the proxy first is another viable solution.
