Generally the servlet extends httpservlet but in the code below
the servlet extends DataSourceServlet
and the page is created like this
The text begins with google.visualization.Query.setResponse
and ends with {c:[{v:'Bob'},{v:'Jane'}]}]}}); on the browser
code: http://code.google.com/apis/visualization/documentation/dev/dsl_csv.html
can you please guide me as to how can i make servlet page silent
without giving the output on the browser.? so that i can directly call the javascript page for drawing the chart
I want to integrate all the code but i am not able to remove this browser from coming.
I am new to servlet please help
Ok I will explain my doubt again
I am writting this servlet code
http://code.google.com/apis/visualization/documentation/dev/dsl_csv.html#intro
the url to execute is /CsvDataSourceServlet?url=http://localhost:8084/WebApplication1/F2.csv
When i execute this code i get output result on my browser ... I am not understanding how that code is opening my browser and showing
{c:[{v:'Bob'},{v:'Jane'}]}]}}); etc etc
why is this happening , why is the browser opening to show result
can we figure out something from this code
http://code.google.com/apis/visualization/documentation/dev/dsl_csv.html#intro
were F2.csv is my *.csv file
now after executing the code I have to display the result which i have to do using the javascript code as follows

our REST-API should deliver a PDF based on an HTML template.
Our intention is to generate the HTML using ISML, stuff it into the PDF processor and grab the output for the REST response.
What is the best way to implement that with Intershop 7.9?
Rendering the PDF is easy to accomplish using the Intershop PDF creation documentation.
Getting the HTML from an ISML template is more tricky, mostly because of missing examples. But in the ISH code there are two example classes hidden:
PageEntryPoint2PDFInteractionProcessor:TemplateCallable
MailMgrImpl:MailTemplateCallable
Both can grab HTML from ISML coming from two different places.
LocaleMgr localeMgr = NamingMgr.getManager(LocaleMgr.class);
String webpageContent = "";
// put some demo stuff into the PD
PipelineDictionary dict = new PipelineDictionaryImpl();
dict.put("foo", "foo");
Request request = Request.getCurrent();
ExecutorService executorService = Executors.newCachedThreadPool();
try {
// demo code, you might want to use another template than Empty.isml
TemplateCallable callable = new TemplateCallable("Empty", localeMgr,
dict, request);
Future<ServletResponse> future = executorService.submit(callable);
ServletResponse fwResponse = future.get();
webpageContent = fwResponse.getContent();
} catch (Exception e) {
Logger.error(this, "Error while getting template render result.");
}
The code for the Callable-Class you on can derive from the example classes I mentioned above.
I'm developing a simple custom tag template for Google Tag Manager. It's supposed to bind to some events and send event data to our servers as JSON in the body of a POST request.
The sandboxed GTM Javascript runtime provides the sendPixel() API. However, that only provides GET requests.
How one sends a POST request from within this sandboxed runtime?
You can use a combination of the injectScript and copyFromWindow APIs found here Custom Template APIs.
Basically, the workflow goes like this.
Build a simple script that contains a function attached to the window object that sends a normal XHR post request. The script I made and use can be found here: https://storage.googleapis.com/common-scripts/basicMethods.js
Upload that script somewhere publically accessible so you can import it into your template.
Use the injectScript API to add the script to your custom template.
The injectScript API wants you to provide an onSuccess callback function. Within that function, use the copyWindow api to grab the post request function you created in your script and save it as a variable.
You can now use that variable to send a post request the same way you would use a normal JS function.
The script I included above also includes JSON encode and Base64 encode functions which you can use the same way via the copyWindow api.
I hope that helps. If you need some specific code examples for parts I can help.
According to #Ian Mitchell answer - I've made similar solution.
This is the basic code pattern that can be used inside GTM template code section in such as scenario:
const injectScript = require('injectScript');
const callInWindow = require('callInWindow');
const log = require('logToConsole');
const queryPermission = require('queryPermission');
const postScriptUrl = 'https://myPostScriptUrl'; //provide your script url
const endpoint = 'https://myEndpoint'; //provide your endpoint url
//provide your data; data object contains all properties from fields tab of the GTM template
const data = {
sessionId: data.sessionId,
name: data.name,
description: data.description
};
//add appropriate permission to inject script from 'https://myPostScriptUrl' url in GTM template's privileges tab
if (queryPermission('inject_script', postScriptUrl)) {
injectScript(postScriptUrl, onSuccess, data.gtmOnFailure, postScriptUrl);
} else {
log('postScriptUrl: Script load failed due to permissions mismatch.');
data.gtmOnFailure();
}
function onSuccess() {
//add appropriate permission to call `sendData` variable in GTM template's privileges tab
callInWindow('sendData', gtmData, endpoint);
data.gtmOnSuccess();
}
It's important to remember to add all necessary privillages inside GTM template. Appropriate permissions will show automatically in privillages tab after use pertinent options inside code section.
Your script at 'https://myPostScriptUrl' may looks like this:
function sendData(data, endpoint) {
var xhr = new XMLHttpRequest();
var stringifiedData = JSON.stringify(data);
xhr.open('POST', endpoint);
xhr.setRequestHeader('Content-type', 'application/json');
xhr.send(stringifiedData);
xhr.onload = function () {
if (xhr.status.toString()[0] !== '2') {
console.error(xhr.status + '> ' + xhr.statusText);
}
};
}
It is not strictly necessary to load an external script. While still a workaround, you can also pass a fetch reference into the tag through a "JavaScript Variable" type variable:
Create a GTM variable of type "JavaScript Variable" with the content "fetch", thus referencing "window.fetch"
Add a text field to your Custom Tag, e. g. named "js.fetchReference".
Use data.fetchReference in your Custom Tag's like you normally would use window.fetch
Make sure the tag instance actually references the variable created in step 2 with {{js.fetchReference}}
I jotted this down with screenshots at https://hume.dev/articles/post-request-custom-template/
I am trying to use the jQuery UI autocomplete feature in my web application. What I have set up is a page called SearchPreload.aspx. This page checks for a value (term) to come in along with another parameter. The page validates the values that are incoming, and then it pulls some data from the database and prints out a javascript array (ex: ["item1","item2"]) on the page. Code:
protected void Page_Load(object sender, EventArgs e)
{
string curVal;
string type ="";
if (Request.QueryString["term"] != null)
{
curVal = Request.QueryString["term"].ToString();
curVal = curVal.ToLower();
if (Request.QueryString["Type"] != null)
type = Request.QueryString["Type"].ToString();
SwitchType(type,curVal);
}
}
public string PreLoadStrings(List<string> PreLoadValues, string curVal)
{
StringBuilder sb = new StringBuilder();
if (PreLoadValues.Any())
{
sb.Append("[\"");
foreach (string str in PreLoadValues)
{
if (!string.IsNullOrEmpty(str))
{
if (str.ToLower().Contains(curVal))
sb.Append(str).Append("\",\"");
}
}
sb.Append("\"];");
Response.Write(sb.ToString());
return sb.ToString();
}
}
The db part is working fine and printing out the correct data on the screen of the page if I navigate to it via browser.
The jQuery ui autocomplete is written as follows:
$(".searchBox").autocomplete({
source: "SearchPreload.aspx?Type=rbChoice",
minLength: 1
});
Now if my understanding is correct, every time I type in the search box, it should act as a keypress and fire my source to limit the data correct? When I through a debug statement in SearchPreload.aspx code behind, it appears that the page is not being hit at all.
If I wrap the autocomplete function in a .keypress function, then I get into the search preload page but still I do not get any results. I just want to show the results under the search box just like the default functionality example on the jQuery website. What am I doing wrong?
autocomplete will NOT display suggestions if the JSON returned by the server is invalid. So copy the following URL (or the returned JSON data) and paste it on JSONLint. See if your JSON is valid.
http://yourwebsite.com/path/to/Searchpreload.aspx?Type=rbChoice&term=Something
PS: I do not see that you're calling the PreLoadStrings function. I hope this is normal.
A couple of things to check.
Make sure that the path to the page is correct. If you are at http://mysite.com/subfolder/PageWithAutoComplete.aspx, and your searchpreload.aspx page is in another directory such as http://mysite.com/anotherFolder/searchpreload.aspx the url that you are using as the source would be incorrect, it would need to be
source: "/anotherFolder/Searchpreload.aspx?Type=rbChoice"
One other thing that you could try is to make the method that you are calling a page method on the searchpreload.aspx page. Typically when working with javascript, I try to use page methods to handle ajax reqeusts and send back it's data. More on page methods can be found here: http://www.singingeels.com/Articles/Using_Page_Methods_in_ASPNET_AJAX.aspx
HTH.
This should be trivial, and I'm pretty sure I did it once before.
I'm trying to post data up to a server and have it bounced back to me as a file download, prompting the native browser file download box. I know the server part works just fine becasue I can post from a demo web form, but when I run the following Flex 3 code, I can't even get the request to fire.
var fileRef:FileReference = new FileReference();
private function saveXmlAsFile(event:MouseEvent):void
{
var fileRequest:URLRequest = new URLRequest();
fileRequest.method = URLRequestMethod.POST;
fileRequest.url = "http://foo.com/dataBounce";
var urlVariables:URLVariables = new URLVariables();
urlVariables.content = "Test content to return" ;
// fileRequest.contentType = "application/x-www-form-urlencoded ";
urlVariables.fileName = "test.xml";
fileRef.addEventListener(SecurityEvent.ALL, onSecurityError);
fileRef.addEventListener(SecurityErrorEvent.SECURITY_ERROR, onSecurityError2);
fileRef.addEventListener(IOErrorEvent.NETWORK_ERROR, onNetworkError);
fileRef.addEventListener(Event.COMPLETE, onComplete);
try
{
fileRef.download(fileRequest, "test.xml");
}catch(error:Error) {
model.logger.error("unable to download file");
}
}
Note, when the call to fileRef.download is called, I can't see any request being made across the network using the traditional Firebug or HTTPWatch browser tools.
EDIT: I should add that this is for < Flash Player 10, so I can't use the newer direct save as file functionality.
Any suggestions? Thanks.
You need to add fileRef.upload to trigger the upload.
Also I would move the download statement to the onComplete so the file isn't requested before it's been uploaded.
Your explanation is pretty clear, but when I look at your code, I'm feel like I'm missing something.
The code looks like you're trying to do half of the upload part and half of the download part.
I think the code you currently have posted would work to trigger a download if you set the .method value to GET. I believe you will also need to include the filename as part of the .url property.
However, to post something and then trigger a download of it, you need two separate operations - the operation to post the data and then an operation to download it, which should probably be called from the upload operation's onComplete handler.
OK, I believe I figured out one of the things that's going on.
When you don't set the URLRequest.data property, it defaults the request method to "GET".
So, the working code looks like, with the data set to the posted URL variables:
private var fileRef:FileReference;
private function saveRawHierarchy(event:MouseEvent):void
{
var fileRequest:URLRequest = new URLRequest();
fileRequest.method = URLRequestMethod.POST;
fileRequest.url = "http://foo/bounceback";
var urlVariables:URLVariables = new URLVariables();
urlVariables.content = "CONTENT HERE";
urlVariables.fileName = "newFileName.xml";
fileRequest.data = urlVariables;
fileRef = new FileReference();
fileRef.addEventListener(Event.COMPLETE, onComplete);
try
{
fileRef.download(fileRequest, "appHierarchies.xml");
}catch(error:Error) {
model.logger.error("unable to download file");
}
}
Not sure what was wrong about the request not being made before, though.
I don't know much about Flash but we are working on a site that has a flash form and when the users pick an option, like selecting a value from a drop down list, we need the value to be passed to asp.net server-side code. What's the easiest way to do this?
Flash can invoke server side service. So use GET or POST to pass data
You could explore these options:
1) Communicate between the SWF and the containing page through JavaScript
2) Communicate via asp.net webservices from the SWF directly to the webservice.
3) Not sure but could probably do a POST to a processing aspx page?
HTH
I think a good option is to use the XML class so consider this:
var xmlRequest = new XML();
xmlRequest.onLoad = parseXMLResponse;
xmlRequest.load("http://yourpathtoyourserver/file.aspx?listselectedvalue=something");
function parseXMLRequest(loaded)
{
trace("hi");
}
You can also have the page give you data back this way so it's not just one way communication.
Assuming you are using Action Script 2.
Read the important notes at the bottom of each codes pertain to sending and retrieving data from flash to .net page. Explanation of the code is in the comment inside the code.
Flash Part (Action Script 2)
//function to send collected form data to asp.net page
//use other control/button to call this function
//important: in order for the 'onLoad' event to work correctly, this function has to be 'Void'
function sendForm():Void
{
//create LoadVars object
var lv_in:LoadVars = new LoadVars();
var lv_out:LoadVars = new LoadVars();
//set onLoad event
lv_in.onLoad = function(success:Boolean)
{
//if success, meaning data has received from .net page, run this code
if (success)
{
//lv_in.status is use to get the posted data from .Net page
statusMsg.text = "Thank you for filling up the form!" + lv_in.status;
}
//if fail, run this code
else
{
statusMsg.text = "The form you are trying to fill up has an error!";
}
}
//this is the collected data from the form
lv_out.userName = txtUserName.text;
lv_out.userAddress = txtUserAddress.text;
lv_out.userBirthday = txtUserBirthday.text;
//begin invoke .net page
lv_out.sendAndLoad("ProcessDataForm.aspx", lv_in, "POST");
}
Important note:
The function that contain onLoad event, in this case sendForm function, has to be Void function, meaning it's not returning value. If this function return value, what happen is the function will be executed all the way without waiting for the returned data from .net page, thus the onLoad event will not be set properly.
.Net Part
public void ProcessData
{
//process the data here
Response.Write("status=processed&");
}
Important note:
To send data/message back to flash, you can use Response.Write. However, if you want Action Script to parse the posted message/data from .Net page keep in mind you have to include & symbol at the end of the message. When parsing data/message, Action Script will stop at & symbol, thus leave the rest of the message alone and only get the message under sent variable.
