load initial data - Push solution - Example

Can anyone help by posting a sample java httpClient program that calls the Orbeon with request attribute?

Hi Vedha,

Could you tell us more about what you are trying to do? Typically, it
is forms that call services, nio the other way around.

Re: load initial data - Push solution - Example

Here is what we are trying to do,

Our xForms,

<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:xf="http://www.w3.org/2002/xforms"
xmlns:xxf="http://orbeon.org/oxf/xml/xforms"
xmlns:ev="http://www.w3.org/2001/xml-events">
<head>
<title>Push initial form data to XForms from Java</title>
<xf:model>

<xf:instance id="user-data">
<registration xmlns="">
<first-name></first-name>
<last-name/>
</registration>
</xf:instance>

<xf:insert ev:event="xforms-model-construct-done"
ref="instance('user-data')" origin="xxf:get-session-attribute('firstname')"/>

</xf:model>
<style type="text/css"> .xforms-label { display: block; } fieldset { width: 15em; margin-top: 1em; } </style> </head>
<body>
<fieldset>
<legend>Registration</legend>
<xf:input ref="first-name">
<xf:label>First name</xf:label>
</xf:input>
<xf:input ref="last-name">
<xf:label>Last name</xf:label>
</xf:input>
</fieldset>
</body>
</html>

I am calling this Form from Java code like this and expecting the instance to be replaced with request parater(my-user-data), but it is not getting replaced. Please help,

List<NameValuePair> params = new LinkedList<NameValuePair>();

String dataXml = "<registration><first-name>Vedhagiri</first-name></registration>";

// params.add(new BasicNameValuePair("my-user-data", "Vedhagiri"));

// String encoded = URLEncodedUtils.

String url = "http://localhost:8080/orbeon/xforms-espresso/?" + "my-user-data=" + dataXml;

// HttpGet httpget = new HttpGet(url);
System.out.println(url);

HttpGet get = new HttpGet(url);
get.addHeader("User-Agent", USER_AGENT);
HttpResponse response = client.execute(get);
BufferedReader in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
String inputLine;
StringBuffer response1 = new StringBuffer();

while ((inputLine = in.readLine()) != null) {
response1.append(inputLine);
}
in.close();

PrintWriter printWriter = new PrintWriter(new File("C:\\database\\sample.txt"));
printWriter.print(response1);
printWriter.close();

Hi Vedha,

Got it, then the method described in this thread should do it:

http://discuss.orbeon.com/Load-initial-data-Not-working-td4659835.html

And if this is indeed the same question, I suggest we continue the
discussion on that other thread.
