I have spent a while going over all of the examples on http://www.silverlight.net/learn/quickstarts/
And I'm still pretty lost about Silverlight. I'm not understanding exactly how it gets 'on' to the website. Like... is there any kind of tutorial that shows how you make an HTML webpage that retrieves a silverlight page and displays it, so you can work with it?
All I've had to work with so far are the default generated .aspx files, which don't really tell me much. And even using the default 'MVC Application' generator from Visual Studio is kind of cloudy and fuddled up.
I've done some google searches and glanced around at references, but maybe I'm just kind of dumb. I'm just not getting where it all 'comes together', so to speak. Any hints? Or am I just beyond learning?
The short answer is that you include Silverlight applications in a web page by using an object tag in HTML. The web browser is then responsible for loading the silverlight application similar to the way it loads Flash applications. Check out these quickstarts for a more detailed explanation. Don't be discouraged, this is a new concept to a lot of developers :).
Here is an example of a Silverlight application being embedded in a web page:
<body>
<form id="form1" runat="server" style="height:100%">
<div id="silverlightControlHost">
<object data="data:application/x-silverlight-2,"
type="application/x-silverlight-2"
width="100%" height="100%">
<param name="source" value="HelloWorld.xap"/>
<param name="onError" value="onSilverlightError" />
<param name="background" value="white" />
<param name="minRuntimeVersion" value="4.0.50401.0" />
<param name="autoUpgrade" value="true" />
<a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=4.0.50401.0"
style="text-decoration:none">
<img src="http://go.microsoft.com/fwlink/?LinkId=161376"
alt="Get Microsoft Silverlight" style="border-style:none"/>
</a>
</object>
<iframe id="_sl_historyFrame"
style="visibility:hidden;height:0px;width:0px;border:0px">
</iframe>
</div>
</form>
</body>
Here is the Microsoft tutorial on Embedding Silverlight into HTML. The .xap is the equivalent to Jnlp for modern applets and .swf for Flash. The parameters can control the code and can also be updated via Javascript. The silverlight plugin within the browser executes the application code. HTML just holds it in place.
Just create a Silverlight Application and choose for it to create aHost the Silverlight Application in a Web site.
It will create a project that generates the page that contains silverlight object that loads the xap file on the client.
The xap file is located in the ClientBin, the xap file is the Silverlight application.
As long as you point the object source <param> to the path of the xap file, it should load the respective Silverlight App.
The project it creates:

I am trying to display a bar chart on click of button on a page which is test.jsp. I am able to display the chart,but it opens as a image in the same browser where my test.jsp is.I want to display it in a new Window ,how can I do that. I am using Struts2 and Jfreechart:
Following is my action :
public class TestAction extends ActionSupport{
public String execute() throws Exception {
//code to populate DataSet
chart = ChartFactory.createBarChart(
"Bar Chart", //Chart title
"", //Domain axis label
"MARKETS", //Range axis label
dataSet, //Chart Data
PlotOrientation.VERTICAL, // orientation
true, // include legend?
true, // include tooltips?
false // include URLs?
);
chart.setBorderVisible(true);
return SUCCESS;
}
}
Following is my struts.xml :
<action name="testAction"
class="testAction"
method="execute">
<result name="success" type="chart">
<param name="value">chart</param>
<param name="type">jpeg</param>
<param name="width">600</param>
<param name="height">400</param>
</result>
</action>
<action name="displayDataAction"
class="testAction"
method="getData">
<result name="success">test.jsp</result>
</action>
Jsp is :
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%# taglib prefix="s" uri="/struts-tags"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Data</title>
<s:head theme="ajax" debug="true"/>
</head>
<body bgcolor="white">
<s:form validate="true" target="_blank">
<table>
//Mapping of data from database
</table>
<s:submit id="submit" value="Display Chart" align="left" action="testAction"/>
<s:submit value="Display Data" align="left" action="displayDataAction"/>`
</s:form>
</body>
</html>
Instead of using s:form tag and s:submit, use form tag like:
<form action="blah blah" target="_blank">
And that should resolve the issue.
I have test.jsp which has two buttons.on click of Display Chart button,it should open chart on new page which is happening using target=_blank in form tag. But problem is i don't want this behavior on click of Display Data button. On click of this button,I want to display data fetched on same page only,but currently for this button as well it is opening a new window .
My code is:
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%# taglib prefix="s" uri="/struts-tags"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

chart = ChartFactory.createBarChart(
"Bar Chart", //Chart title

"MARKETS", //Range axis label
dataSet, //Chart Data
PlotOrientation.VERTICAL, // orientation
true, // include legend?
true, // include tooltips?
false // include URLs?
);
chart.setBorderVisible(true);
return SUCCESS;
}
}
struts.xml:
<action name="testAction"
class="testAction"
method="execute">
<result name="success" type="chart">
<param name="value">chart</param>
<param name="type">jpeg</param>

</result>
</action>
<action name="displayDataAction"
class="testAction"
method="getData">
<result name="success">test.jsp</result>
</action>
I got it done as follows :

Using primefaces fileupload i am trying to show recently uploaded image in img tag just above the upload compontent but it shows only after i manually press F5 or hit enter on browser i have tried location.reload() and histry.go(0) but image is not loading
<img height="100" src="relativepath/productId"/>
<p:fileUpload oncomplete="history.go(0)" fileUploadListener="#{productController.upload}" mode="advanced"
dragDropSupport="false" allowTypes="/(\.|\/)(gif|jpe?g|png)$/" />
do not limit yourself to javascript. an update after ajax, with a timestamp parameter in url will work fine.
this should be the xhtml code:
<h:panelGroup id="panelToUpdate">
<img height="100" src="relativepath/productId?t=#{myManagedBean.currentTimeInMillis}"/>
</h:panelGroup>
<p:fileUpload update="panelToUpdate" fileUploadListener="#{productController.upload}"
mode="advanced" dragDropSupport="false" allowTypes="/(\.|\/)(gif|jpe?g|png)$/" />
and this should be the method in your managed bean:
public long getCurrentTimeInMillis()
{
return System.currentTimeMillis();
}
The following code loads the image every 1 second... Hope I helped
<div id="wraper">
</div>
<style>
var t=setInterval(runFunction,1000);
function runFunction() {
document.getElementById("p1").innerHTML = '<img height="100" src="relativepath/productId"/>
<p:fileUpload oncomplete="history.go(0)" fileUploadListener="#{productController.upload}" mode="advanced"
dragDropSupport="false" allowTypes="/(\.|\/)(gif|jpe?g|png)$/" />'
}
</style>
My Struts2 application needs the pagination functionality applied to some records, but what I need to customize is the "Last 1 - 2 - 3 Next" appearance and also have the ability to use a combo box for the selection of how many records should be visible(10 - 20 - 30 - 40 -50).
I have tried two way to accomplish this goal:
1) use display tag library, but I'm not able to customize the appearance, because is auto-generated by the library, and I don't how implement the combo box for select how many records should be visible
2) create my own code for accomplish this functionality but is a job too long and not enough time due to the expiry.
My question is: exists some Struts2 library for realize this functionality? Or, is possible to customize the display tag library for the page scroll bar and the records combo box?
I can give insight from struts2 code base there is no functionality as described by you provided by struts2 in itself..
Regarding the Display tag i have not used them much but since they are the part of oprn source i am sure we can customize that one more thing regarding the customization of display tag ask question under display tag you will get better answer at at quick pace
I wrote a custom tld just for the purpose as below and then just use it like this:
Usage:
paginate.tag
1}">
<c:set var="showingPage"
value="${param.pageNumber == null ? 1 : param.pageNumber}" />
<c:url value="${postUrl}" var="previousUrl">
<c:param name="pageNumber" value="${showingPage - 1}" />
<c:param name="perPage" value="${perPage}" />
</c:url>
<c:url value="${postUrl}" var="nextUrl">
<c:param name="pageNumber" value="${showingPage +1}" />
<c:param name="perPage" value="${perPage}" />
</c:url>
<div class="pagination" />
<c:if test="${showingPage > 1}">
<< Previous
</c:if>
<fmt:formatNumber var="endCounter" pattern="0">
<%= totalCount % perPage > 0 ? Math.ceil(totalCount/perPage) + 1 : totalCount/perPage %>
</fmt:formatNumber>
<c:forEach begin="1" end="${endCounter}" var="index">
<c:url value="${postUrl}" var="url">
<c:param name="pageNumber" value="${index}" />
<c:param name="perPage" value="${perPage}" />
</c:url>
${index}
</c:forEach>
<c:if test="${endCounter != showingPage}">
Next >>
</c:if>
</div>
</c:if>

How do you post data to an iframe?
Depends what you mean by "post data". You can use the HTML target="" attribute on a <form /> tag, so it could be as simple as:
<form action="do_stuff.aspx" method="post" target="my_iframe">
<input type="submit" value="Do Stuff!">
</form>
<!-- when the form is submitted, the server response will appear in this iframe -->
<iframe name="my_iframe" src="not_submitted_yet.aspx"></iframe>
If that's not it, or you're after something more complex, please edit your question to include more detail.
There is a known bug with Internet Explorer that only occurs when you're dynamically creating your iframes, etc. using Javascript (there's a work-around here), but if you're using ordinary HTML markup, you're fine. The target attribute and frame names isn't some clever ninja hack; although it was deprecated (and therefore won't validate) in HTML 4 Strict or XHTML 1 Strict, it's been part of HTML since 3.2, it's formally part of HTML5, and it works in just about every browser since Netscape 3.
I have verified this behaviour as working with XHTML 1 Strict, XHTML 1 Transitional, HTML 4 Strict and in "quirks mode" with no DOCTYPE specified, and it works in all cases using Internet Explorer 7.0.5730.13. My test case consist of two files, using classic ASP on IIS 6; they're reproduced here in full so you can verify this behaviour for yourself.

I would be very interested to hear of any browser that doesn't run these examples correctly.
An iframe is used to embed another document inside a html page.
If the form is to be submitted to an iframe within the form page, then it can be easily acheived using the target attribute of the tag.
Set the target attribute of the form to the name of the iframe tag.
<form action="action" method="post" target="output_frame">
<!-- input elements here -->
</form>
<iframe name="output_frame" src="" id="output_frame" width="XX" height="YY">
</iframe>
Advanced iframe target use
This property can also be used to produce an ajax like experience, especially in cases like file upload, in which case where it becomes mandatory to submit the form, in order to upload the files
The iframe can be set to a width and height of 0, and the form can be submitted with the target set to the iframe, and a loading dialog opened before submitting the form. So, it mocks a ajax control as the control still remains on the input form jsp, with the loading dialog open.
Exmaple
<script>
$( "#uploadDialog" ).dialog({ autoOpen: false, modal: true, closeOnEscape: false,
open: function(event, ui) { jQuery('.ui-dialog-titlebar-close').hide(); } });
function startUpload()
{
$("#uploadDialog").dialog("open");
}
function stopUpload()
{
$("#uploadDialog").dialog("close");
}
</script>
<div id="uploadDialog" title="Please Wait!!!">
<center>
<img src="/imagePath/loading.gif" width="100" height="100"/>
<br/>
Loading Details...
</center>
</div>
<FORM ENCTYPE="multipart/form-data" ACTION="Action" METHOD="POST" target="upload_target" onsubmit="startUpload()">
<!-- input file elements here-->
</FORM>
<iframe id="upload_target" name="upload_target" src="#" style="width:0;height:0;border:0px solid #fff;" onload="stopUpload()">
</iframe>
This function creates a temporary form, then send data using jQuery :
function postToIframe(data,url,target){
$('body').append('<form action="'+url+'" method="post" target="'+target+'" id="postToIframe"></form>');
$.each(data,function(n,v){
$('#postToIframe').append('<input type="hidden" name="'+n+'" value="'+v+'" />');
});
$('#postToIframe').submit().remove();
}
target is the 'name' attr of the target iFrame, and data is a JS object :
data={last_name:'Smith',first_name:'John'}
If you want to change inputs in an iframe then submit the form from that iframe, do this
...
var el = document.getElementById('targetFrame');
var doc, frame_win = getIframeWindow(el); // getIframeWindow is defined below
if (frame_win) {
doc = (window.contentDocument || window.document);
}
if (doc) {
doc.forms[0].someInputName.value = someValue;
...
doc.forms[0].submit();
}
...
Normally, you can only do this if the page in the iframe is from the same origin, but you can start Chrome in a debug mode to disregard the same origin policy and test this on any page.
function getIframeWindow(iframe_object) {
var doc;
if (iframe_object.contentWindow) {
return iframe_object.contentWindow;
}
if (iframe_object.window) {
return iframe_object.window;
}
if (!doc && iframe_object.contentDocument) {
doc = iframe_object.contentDocument;
}
if (!doc && iframe_object.document) {
doc = iframe_object.document;
}
if (doc && doc.defaultView) {
return doc.defaultView;
}
if (doc && doc.parentWindow) {
return doc.parentWindow;
}
return undefined;
}
You can use this code, will have to add proper params to be passed and also the api url to get the data.
var allParams = { xyz, abc }
var parentElm = document.getElementBy... // your own element where you want to create the iframe
// create an iframe
var addIframe = document.createElement('iframe');
addIframe.setAttribute('name', 'sample-iframe');
addIframe.style.height = height ? height : "360px";
addIframe.style.width = width ? width : "360px";
parentElm.appendChild(addIframe)
// make an post request
var form, input;
form = document.createElement("form");
form.action = 'example.com';
form.method = "post";
form.target = "sample-iframe";
Object.keys(allParams).forEach(function (elm) {
console.log('elm: ', elm, allParams[elm]);
input = document.createElement("input");
input.name = elm;
input.value = allParams[elm];
input.type = "hidden";
form.appendChild(input);
})
parentElm.appendChild(form);
form.submit();
