How to get video src with jsoup (twitch)?

I am getting null pointer, is possible to get this link?
Element element = document.select("div.tw-absolute.tw-bottom-0.tw-left-0.tw-overflow-hidden.tw-right-0.tw-top-0.video-player__container").first();
System.out.println(element.absUrl("src"));
Tried this too
nullpointer as well
Element video = document.select("video").first();
String absSrc = video.absUrl("src");
System.out.println(absSrc);
html part
<div class = "tw-absolute tw-bottom-0 tw-left-0 tw-overflow-hidden tw-right-0 tw-top-0 video-player__container" data-test-selector="video-player__video-container">
<video playsinline="" webkit-playsinline="" src="https://clips-media-assets2.twitch.tv/40487770748-offset-9048.mp4?token=%7B%22authorization%22:%7B%22forbidden%22:false,%22reason%22:%22%22%7D,%22chansub%22:%7B%22restricted_bitrates%22:%5B%5D%7D,%22device_id%22:%226518a1542e035018%22,%22expires%22:1609419047,%22https_required%22:true,%22privileged%22:false,%22user_id%22:500437676,%22version%22:2,%22vod_id%22:850278065%7D&sig=5e17731db577b99e535c4aad3eacc70c0cc34521"></video>

Looks like this one will require again, a lot of work to unpick.
Here's what I can tell you just from a quick look:
when you make the initial request, it does not contain the result you're looking for in the HTML. Therefore it must be coming from a subsequent HTTP request that is fired off once the page is loaded... i.e. there's javascript communicating with back end servers to get JSON payloads. In one of those payloads you'll find ".mp4".
If you use Chrome developer tools, you can flick over to the "Network" tab, click on each request following the first one, and check the "Preview" tab. You will find some requests contain JSON responses, others are just .css, .png, etc. ignore these. In the JSON responses, check the results for the occurrence of some generic value you're interested in like ".mp4". Once you've found it:
.. you then need to try to recreate the headers, the request body (as its not empty), the type of HTTP request (POST), and pass any relevant cookies (in the headers).
You're going to have to make anywhere between 1 and 5 HTTP requests to get what you need to get this JSON payload. Once you have it you can then parse it back.
This is another one of those jobs that's so big I'm not going to begin to try to do it for you.
If it were me doing the job, I'd check the Twitch API docs https://dev.twitch.tv/docs/api/ to see if there's a better/easier way that's just 1-2 requests.

You can change the CSS query as below.
Element element = document.select("div.tw-absolute.tw-bottom-0.tw-left-0.tw-overflow-hidden.tw-right-0.tw-top-0.video-player__container > video").first();
String src = element.attr("src");
System.out.println(src);

Using the NCDC's Climate Data Online API with Java

I have never used a RESTful API. I want to use this API to get historical weather data, but I can't find a simple tutorial taking me from end to end making an app that uses a RESTful API in Java. I'm not sure what steps I should take to get the data.
The steps listed on the getting started page are not Java specific, so I'm not sure how to use that info. I have requested a token and got it, so I'm good on that front.
What I need help with is getting a minimal example showing how, with just a token and formatted URL, you can get JSON data from the API.
Some things I've looked into are javax.ws.rs and jersey client, but I'm not sure how to use those either.
Thanks in advance :)

Using Fetch you can do:
fetch(url, {options})
.then(data => {
// Do some stuff here
})
.catch(err => {
// Catch and display errors
})
Where the url is the one from the getting started page.
And you can get whatever data you need from data.
Say you need to save just the name in a local var, then you do:
.then(data => {
name = data.name
})

Creating a filter to check a case for a letter in a field in the json body in REST assured

I have a request in the form of json,which looks like this.
{"User":{"email":"test#test.com","FName":"fname"}}
When I try to send it via REST assured ,the U in the User is seen to change its case.i.e. changes to a lower case.
To send the request I have created my own serialized classes. The end-point is seen like this:
{"user":{"email":"test#test.com","FName":"fname"}}
but somehow it is not changing the case of the remaining fields.I don't knwo why this is happening.
I've even tried to create a filter for a request specification,but couldn't go any further with that too. I also then thought of first converting the serialized object to a gson,and then check the case of the User, still no luck.
Error I get is:
The class, User,does not match the payload object for payload.
Please note I am trying to use the service of another team,so I really don't have an access to their code-base(Although not needed).Observe the space between the first , and user in the above message, is it worth noting?

I finally got away with it by converting the object(JSON) into a JSON string/payload.
And while passing it as a form parameter,passed the string/payload.
Somehow,still couldn't figure out why the formparameter/formparam option in RESTAssured did not allow the serialized object to go through. But,anyway got around it this time.
Thanks for the suggestions all.

How do I invoke a template from another template in Play Framework?

I have a template accountlist.scala.html looking like this:
#(accounts: models.domain.AccountList)
#titlebar = {<p>some html</p>}
#content = {
#for(account <- accounts) {
<p>#account.name</p>
}
}
#main(titlebar)(content)
... and another template account.scala.html like this:
#(account: models.domain.Account)
#titlebar = {<p>#account.name</p>}
#content = {
#for(transaction <- account.getTransactions()) {
<p>#transaction.detail</p>
}
}
#main(titlebar)(content)
From both of them I am invoking the template main.scala.html.
I have access to the entire Account POJO in the first view accountlist.scala.html, so really there is no need for me to invoke the server to get the details of the account when I go to the view in which I display the details. I would just like to change view on the client side. How could I call the second view account.scala.html from the view accountlist.scala.html a user clicks on an account in the list? I am ready to change the templates as needed.

I have provided a previous answer, which is still available at the end of this post. From your comments, however I understand that you are asking for something else without understanding how dangerous it is.
There are three ways of handling your use case, let's start with the worst one.
A stateful web application
If you have loaded data into a Pojo from some data source and you want to re-use the Pojo between multiple requests, what you are trying to do is to implement some kind of client-state on the server, such as a cache. Web applications have been developed in this way for long time and this was the source of major bugs and errors. What happens if the underlying account data in the database is updated between one http request and the following? Your client won't see it, because it use cached data. Additionally, what happens when the user performs a back in his browser? How do you get notified on the server side so you keep track of where the user is in his navigation flow? For these and others reasons, Play! is designed to be stateless. If you are really into web applications, you probably need to read about what is the REST architectural style.
A stateless web application
In a stateless web applications, you are not allowed to keep data between two http requests, so you have two ways to handle it:
Generate the user interface in a single shot
This is the approach which you can use when your account data is reduced. You embed all the necessary data from each account into your page and you generate the view, which you keep hidden and you show only when the user clicks. Please note that you can generate the HTML on the server side and with Javascript makes only certain part of your DOM visible, or just transfer a JSON representation of your accounts and use some kind of templating library to build the necessary UI directly on the client
Generate the user interface when required
This approach becomes necessary when the account data structure contains too many informations, and you don't want to transfer all this information for all the accounts on the client at first. For example, if you know the user is going to be interested in seeing the details only of very few accounts, you want to require the details only when the user asks for it.
For example, in your list of accounts you will have a button associated with each account, called details and you will use the account id to send a new request to the server.
#(accounts: models.domain.AccountList)
#titlebar = {<p>some html</p>}
#content = {
#for(account <- accounts) {
<p>#account.name <button class="details" href="#routes.Controllers.account(account.id)">details</button></p>
}
}
Please note that you can also generate the user interface on the client side, but you will still need to retrieve it from the server the data structures when the user clicks on the button. This will ensure that the user retrieves the last available state of the account.
Old answer
If your goal is to reuse your views, Play views are nothing else then Scala classes, so you can import them:
#import packagename._
and then you use it in another template:
#for(account <- accounts) {
#account(account)
}

The question reveals a misunderstanding of play framework templates. When compiling the play project the template code is transformed to html, css and javascript.
You can not "invoke"/link another template showing the account transactions from a href attribute of your Account row. However, you can do any of the following:
In case you have loaded all transactions from all accounts to the client in one go: extend the template to generate separate <div> sections for each account showing the transactions. Also generate javascript to 1) hide the overview div and 2) show the specific transaction div when clicking on one of the accounts in the overview. Please see the knockout library proposed by Edmondo1984 or the accordion or tabs in twitter bootstrap.
In case you only load the account overview from the server. Generate a link such as this one href="#routes.Controllers.account(account.id)" (see Edmondo1984 answer) and make another template to view this data.
Since the question concerned a case in which you got all data from the server, go by option 1.

PHP how to consume SOAP web services?

I'm very new in using web services. Appreciate if anyone can help me on this.
In my PHP codes, I'm trying to use the SOAP web services from another server (JIRA, java). The JIRA SOAP API is shown here.
$jirasoap = new SoapClient($jiraserver['url']);
$token = $jirasoap->login($jiraserver['username'], $jiraserver['password']);
$remoteissue = $jirasoap->getIssue($token, "issuekey");
I found that my codes have no problem to call the functions listed on that page. However, I don't know how to use the objects returned by the API calls.
My question are:
In my PHP codes, how can I use the methods in the Java class objects returned by SOAP API calls?
For example, the function $remoteissue = $jirasoap->getIssue($a, $b) will return a RemoteIssue. Based on this (http://docs.atlassian.com/rpc-jira-plugin/latest/com/atlassian/jira/rpc/soap/beans/RemoteIssue.html), there are methods like getSummary, getKey, etc. How can I use these functions in my codes?
Based on some PHP examples I found from the internet, it seems that everyone is using something like this:
$remoteissue = $jirasoap->getIssue($token, "issuekey");
$key = $remoteissue->key;
They are not using the object's methods.
Refer to this example, it seems that someone is able to do this in other languages. Can it be done in PHP too?
The problem I'm facing is that, I am trying to get the ID of an Attachment. However, it seems that we can't get the Attachment ID using this method: $attachmentid = $remoteattachment->id;. I am trying to use the $remoteattachment->getId() method.
In PHP codes, after we made a SOAP API call and received the returned objects, how do we know what data fields are available in that object?
For example,
$remoteissue = $jirasoap->getIssue($token, "issuekey");
$summary = $remoteissue->summary;
How do we know ->summary is available in $remoteissue?
When i refer to this document (http://docs.atlassian.com/rpc-jira-plugin/latest/com/atlassian/jira/rpc/soap/beans/RemoteIssue.html), I don't see it mention any data fields in RemoteIssue. How do we know we can get key, summary, etc, from this object? How do we know it is ->summary, not ->getsummary? We need to use a web browser to open the WSDL URL?
Thanks.

This question is over one year old, but to share knowledge and provide an answer to people who have this same question and found this page, here are my findings.
The document mentioned in the question is an overview of the JiraSoapService interface. This is a good reference for what functions can be called with which arguments and what they return.
If you use Java for your Jira SoapClient the returned objects are implemented, but if you use PHP, the returned objects aren't of the type stated in this documentation and do not have any of the methods mentioned. The returned objects are instances of the internal PHP class stdClass, which is a placeholder for undefined objects. The best way to know what is returned is to use var_dump() on the objects returned from the SoapCalls.
$jirasoap = new SoapClient($jiraserver['url']);
$token = $jirasoap->login($jiraserver['username'], $jiraserver['password']);
$remoteissue = $jirasoap->getIssue($token, "PROJ-1");
var_dump($remoteissue);
/* -- You will get something like this ---
object(stdClass)#2 (21) {
["id"]=> string(3) "100"
["affectsVersions"]=> array(0) { }
["assignee"]=> string(4) "user"
...
["created"]=> string(24) "2012-12-13T09:27:49.934Z"
...
["description"]=> string(17) "issue description"
....
["key"]=> string(6) "PROJ-1"
["priority"]=> string(1) "3"
["project"]=> string(4) "PROJ"
["reporter"]=> string(4) "user"
["resolution"]=> NULL
["status"]=> string(1) "1"
["summary"]=> string(15) "Project issue 1"
["type"]=> string(1) "3"
["updated"]=> string(24) "2013-01-21T16:11:43.073Z"
["votes"]=> int(0)
}
*/
// You can access data like this:
$jiraKey = $remoteissue->key;
$jiraProject = $remoteissue->project;

The document you referred to in #2 is to a Java implementation and really doesn't give you any help with PHP. If they do not publish a public API for their service (which would be unusual), then using the WSDL as a reference will let you know what objects and methods are accepted by the service and you can plan your method calls accordingly.
The technique you used to call getIssue(...) seems fine, although you should consider using try...catch in case of a SoapException.

I have used Jira SOAP in .NET project and IntelliSense hinted me what fields are available for returned object.
You can use something like VS.Php for Visual Studio or Php for Visual Studio if you are using Visual Studio.
Or you can choose one of the IDEs from here with support of IntelliSense.
