Remote Scripting With JavaScript and ASP
What is remote scripting?
Remote scripting is a technology that allows us to call server side ASP script from the client using JavaScript. The main benefits of using remote scripting are that it's cross browser compatible (works on NS4.x+ and IE4.x+) and takes away the need to refresh a page when some sort of server action is required to either send/receive data.
The way in which remote scripting works is fairly trivial, and only requires a small amount of tinkering to get it up and running properly. Firstly, you must configure remote scripting on both the client and server (which we will look at next). Once it's configured, you create an ASP page containing all of the functions that you’d like to expose to the client and call them in a special way.These functions are created is the same way that you would create any ASP functions (with the function myFunc()... end function syntax), however some server side JavaScript is also included with the ASP script allowing the client to view your entire ASP page as an object that exposes methods. The remote scripting engine handles all of this under the hood, so we don't need to go into detail about it here.
Installing remote scripting
The technology behind remote scripting is not extremely complicated, and to enable remote scripting capabilities on our IIS web server we only need a handful of files: rs.htm, rsproxy.class and rs.asp. These files are available for download as "Remote Scripting 1.0b" here, and you should download them before continuing.
Once you've installed remote scripting, you should see the following files and folders in the _ScriptLibrary folder under your IIS web folder:
- rs.htm: Contains the plumbing and functions that make remote scripting on the client side possible. Most notably, rs.htm contains three public methods called RSEnableRemoteScripting, RSExecute and RSGetASPObject. Rs.htm is implemented in JavaScript.
- rs.asp: Contains the plumbing and functions that make remote scripting on the server side possible. Its main method is RSDispatch, which handles all marshalling and the returning of data back to the client.
- rsproxy.class: A Java class that is dynamically added to the clients HTML output when rs.htm is called. It handles some of the internals that are required by the remote scripting engine to function correctly including the communication between the client and server scripts.
- /docs: Documentation detailing how to setup remote scripting, how to implement remote scripting into client and server code, etc.
- /samples: Contains a sample that implements remote scripting.

I am trying some remote scripts. I am getting the same error "Failed to create the ASP object: url". I tried installing the JVM, but still i am receiving the error. I am pasting my code here for your reference. I will appreciate if you have any suggestions or comments,
The "snake.htm" calls snake.asp file from the server. The snake.asp and snake.htm are in the same folder on the server. I am running the client browser from the server machine.

All I want to beable to do is have the Remote scripting return a matrix of the querry I submitted. I tried going through the tutorial on remote scripting step by step and can't get the List People SQL tutorial to work. Does anybody know how I can dynamically look up SQL Queries on the serverside and dynamically change my page on the server side?!
The tutorial just hangs never finds any of the users and locks the browser.
Thanks

It requires Microsoft VM to run and also though a very common thing which just slips of our mind - use "../folder/_scriptlibrary" in the client file .
This may be one of the reasons that its giving an error "Object doesn't support this property or method"
Hi Anil,
This looks like solution to my problem,
Romote scripting which was working suddenly stopped working don't know the reason. probably the JVM got changed sometime back Thanks alot. I will try changing JVM....to remote scripting...

Install SP1 for Win XP.
Due to litigation matters, JVM was not included in the release of XP (with IE6), but is now finally available in SP1.

hi there,
hey did you able to run "remote scripting with javascript and asp" tutorial successfully ? if so, pl help me in that.
Thanks,

Hello
I had similar errors to those that you mentioned, i noticed that they occured soon after i had installed the sun jvm, after much head scratching and even altering rs.htm it dawned on me that perhaps the new jvm might be the reason and that i might not have any problems if i used microsofts jvm instead, i dont know if this is for sure, but when i disabled the sun jvm i didn't have any more of the problems that i had, which happen to be very similar to you own
I have in c:\inetpub\wwwroot\test\catalog\config\test.asp which uses the remote scripting by adding this
lines to the code
<body>
....
....
<!-- Incluir para Remote Scripting -->
<script language="JavaScript" src="../../ScriptLibrary/rs.htm"></script>
<script language="JavaScript">RSEnableRemoteScripting("../../ScriptLibrary");</script>

</body>
And it stills gives me the same error:"Object doesn't support this property or method" with a line number not matching a line in the code.
What can I do? I have tried to re-install the rs files and it sill didn't work, what else can I do?
amitmathur23, you have to install the "Remote Scripting 1.0b" for resolve it...
"Object doesn't support this property or method".
When i debeg it, it is found on rs.htm file and on the line where
"this.rsapplet.startRequest(request.id,url_context,url,this.REQUEST_MODE_COMPLETE);" is mentioned.
Please help.
I have tried to run the samples on your article on RS and none of them work. I get an error when RSGetASPObject is invoked.
The problem is in this method MSRSstartRequest. The msg say Object does not support property or method was not handled. Is there something that I'm missing. I using InterDev 6 on Win2k SP2. Pls Help
