How to retrieve data from a web service

Hi
i am at very beginner level about web services.
I am searching for a simple example of retrieving data from a web services, but cant find.
How can i get xml data from a web service. i dont need to develop the web service it is already ready, i just need how could i fetch data from it.
Can somebody point out or give an example?
Thanks in advance

Hi,
just create a skeleton for the Web Service. In JDeveloper, create a new project and then use the "NEW" context menu option.
Navigate to "Business Tier" --> Web Services and select "Web Service Proxy"
In teh following, provide the WSDL reference to create the Java proxy. This gives you accss to the WS without having to parse the XML yourself

How to retrieve data from a jsp page

I have created a page with some text boxes, file, submit button. In my Ist jsp, i am dynamically add Text boxes and File (for Uploading).
In the 2nd jsp, i am used Jakarata FileUpload API. I am able to retrieve all data and files except that value of dynamicall added text boxes. That is, I cannot retrieve data from dynamically added text boxes.
Using Jakarata FileUpload API, i can retrieve values of form data using
getString() method.
I want to know that there is any way or method for retrieving form data values into String Array.

Use parseRequest(request) to get the file information as you already are doing. However, I dont know how you can use request.getParameter("textField1") to get the other fields from the page. My work-around is as follows:
Change your submit button to an ordinary button and add an onClick event to it. Then in the javascript function that supports the onClick, add the textField1 as follows:
<form name="fileUploadForm" method="post" action="someAction" (((more code code here)))))
function submitButtonClick(){
document.fileUploadForm.action=
document.fileUploadForm.action+
"?textField1="+document.fileUploadForm.textField1.value"+
"&textField2="+document.fileUploadForm.textField2.value"+
"&textField3="+document.fileUploadForm.textField3.value";
document.fileUploadForm.submit();
As you can see in the above code, I append the textField1 name/value pair to the end of the action. Now in the server, you can use getParameter("textField1");

How do I add dates from a web page into iCal?

Hello. I would love to find a way to input dates from a web page, into iCal as an event. Right now, if there is a conference or whatever that is on such and such a date, I have to keep the web page open that has the dates and time, and then open iCal, and create a new event on that date, etc. Is there a way to highlight said dates on a web page, run some automation, and voila, it is a new event in iCal?

Don't double tap. Just try pressing on the text. That should highlight it.

Retrieve data from a dynamic page via loadURL

Hello.
I would like to ask you how it is possible to retrieve data
from a dynamic page (asp classic in my case) using the loadURL
method.
I would like to create an html authentication form (with
username and password fields). The loadURL method should call an
asp page and then pass to the usual function 'DoIfSucceded' the
results of the elaboration.
Of course I'm going to have a switch in the function in order
to make different actions depending from the results of the asp
page (authentication succeded or failed).
I had a look to the examples at this page:
Adobe
samples
Is there anyone who can explain clearly how the results data
must be written by the asp page and how the success function can
retrieve them ?
I thank you in advance for your help.

loadURL() uses the the XMLHttpRequest Object so if the
content you return is XML, you have 2 choices for accessing your
data. You can either access it as a text string via the
XMLHttpRequest object's responseText property, or as a DOM document
via the XMLHttpRequest object's responseXML property:
function MySuccessCallback(req)
// If my data is XML, I can access the data that was sent
from the server
// as DOM elements via the XMLHttpRequest's responseXML
property.
var xmlDOM = req.xhRequest.responseXML;
// OR, you can access the data sent back from the server as
text via
// the XMLHttpRequest object's responseText property.
var xmlAsAString = req.xhRequest.responseText;
var req = Spry.Utils.loadURL("GET",
"/app/book.php?id=1&code=54321", true, MySuccessCallback);
If your serverside script wants to use some other format as a
response like JSON or plain text, then you can only access the data
as text via the responseText property.

I am working on an VM on MS BPC.

Error retrieving data from the web server in Excel fo BPC

Hello Everybody,
I'm working with BPC v7.5 , i created some reports with the EVDRE formula and they were working perfectly.
The problem started when i created new users, that in fact have the same access profile and task profile as my user.
i started to test these new users in excel and every time i expand the report this legend appears: " EVDRE Retrying... EVDRE encountered an error retrieving data from the Web Server. Retrying in (X) Seconds...". After waiting a while a push cancel, then appears a window with the legend: Ev4excel Addin, Errors found retriening data.
The funny thing is that when i login back to my user everything works fine again, any idea what could be the problem? the other user have the same permissions.
Thanks a lot in advance!!
Nidia Olguí

very strange. Normally the member access profile must be diifferent. So it is not important the task profile but the member access profile. Can you please double check ?
If you are doing a simple EVDRE with users having problems is it working or you still have problems?
Regards
Sorin Radulescu
