Re: [Laszlo-user] Sending dataset over HTTP

[Peter Brand]

Hi Jean-Baptiste

According to my knowledge of OpenLaszlo socalled data-binding via the 'src'
attribute of 'dataset' is in fact not data-binding but just data-bound
data-retrieval. It's a one-way functionality. Isn't it? 

And again according to my understanding of Laszlo things to
udate/delete/insert data to the 'src' you have to call some server side
program (php, jsp, asp, etc) that can handle data sources (e.g. a XML-file,
a relational DB). Did you read chapter 35: Building Data-Driven
Applications in the software egnineer's guide?

Subject: [Laszlo-user] Sending dataset over HTTP

Hi the list !

I would like to send over HTTP the content of a dataset. Nothing complex
ins't it ?
But I got problems ... Let me explain :
    <dataset name="PetCreate1_pet_embeded_ds">
        <pet
             animal="aaa"
             entryDate="aaa"
             dateBirth="aaa"
             age="aaa"
             name="aaa"
             sex="aaa"
             streetNumber="aaa"
             streetName="aaa"
             code="aaa"
             town="aaa"
        </pet>
    </dataset>

That dataset if mapped via xpath to different text field. (that dataset do
not come from HTTP but is hardcoded like that in the lzx.
Here is the code I use to send the dataset :
            <handler name="onclick">
                var ds = PetCreate1_pet_embeded_ds;
                Debug.write("Seding data ...");
                ds.setAttribute("querytype", "POST");
                ds.setAttribute("type", "http");
                ds.setAttribute("request", "false");
                ds.setAttribute("src", "test/nimportequoi");

                //var param = new LzParam();
                //var xml = ds.getPointer().serialize();
                //Debug.write(xml);
                //param.addValue("xml", xml, true);
                //ds.setQueryString(param);
                ds.doRequest();
            </handler>


As you can see I try different thing to pass the XML.
I have to explicitly add xml string as a param if I want to catch it on the
Servlet.
In other words, with that commented version, no XML on the servlet !
Why ?


In other part of my program I got on the servlet the following error :
2007-10-19 12:21:06.076::WARN:  /petshop/: 
java.net.MalformedURLException: no protocol: <localdata/>

or depending on some line commented or not, 2
2007-10-19 12:21:06.076::WARN:  /petshop/: 
java.net.MalformedURLException: no protocol: <here all the dataset XML>

So I got the XML but with that error everytime.


Any clues ?

thanks !
