Scala - Send Multiple Headers with scalaj.http.Http

I am making a post request with the libraries listed below. It seems like my last header is being cut off. Ive tried the following two ways but neither seems to be working.
import scalaj.http._
import scalaj.http.Http
var result = Http("https://example.com" + Key + "/rowset")
.postData(jsonOutput)
.headers(Seq("Authorization" -> ("Bearer " + accessToken)))
.headers(Seq("content-Type" -> "application/json"))
var result = Http("https://example.com" + Key + "/rowset")
.postData(jsonOutput)
.headers(Seq("Authorization" -> ("Bearer " + accessToken), "content-Type" -> "application/json"))

Just to check; you are doing something with the result variable? It is still just a request and will remain so until you call i.e. result.asString which will execute the request and return the response (HttpResponse[String] in case of asString).

java.lang.NullPointerException trying to get specific values from hashmap

I've spent several frustrating days on this now and would appreciate some help. I have a Java agent in Lotus Domino 8.5.3 which is activated by a cgi:POST from my Lotusscript validation agent which is checking that customer has filled in the Billing and delivery address form. This is the code that parses the incoming data into a HashMap where field names are mapped to their respective values.
HashMap hmParam = new HashMap(); //Our Hashmap for request_content data
//Grab transaction parameters from form that called agent (CGI: request_content)
if (contentDecoded != null) {
String[] arrParam = contentDecoded.split("&");
for(int i=0; i < arrParam.length; i++) {
int n = arrParam[i].indexOf("=");
String paramName = arrParam[i].substring(0, n);
String paramValue = arrParam[i].substring(n + 1, arrParam[i].length());
hmParam.put(paramName, paramValue); //Old HashMap
if (paramName.equalsIgnoreCase("transaction_id")) {
transactionID = paramValue;
description = "Order " + transactionID + " from Fareham Wine Cellar";
//System.out.println("OrderID = " + transactionID);
}
if (paramName.equalsIgnoreCase("amount")) {
orderTotal = paramValue;
}
if (paramName.equalsIgnoreCase("deliveryCharge")) {
shipping = paramValue;
}
}
}
The block of code above dates back over a year to my original integration of shopping cart to Barclays EPDQ payment gateway. In that agent I recover the specific values and build a form that is then submitted to EPDQ CPI later on in the agent like this;
out.print("<input type=\"hidden\" name=\"shipping\" value=\"");
out.println(hmParam.get("shipping") + "\">");
I want to do exactly the same thing here, except when I try the agent crashes with a null pointer exception. I can successfully iterate through the hashMap with the snippet below, so I know the data is present, but I can't understand why I can't use myHashMap.Get(key) to get each field value in the order I want them for the html form. The original agent in another application is still in use so what is going on? The data too is essentially unchanged String fieldnames mapped to String values.
Iterator it = cgiData.entrySet().iterator();
while (it.hasNext()) {
Map.Entry pairs = (Map.Entry)it.next();
out.println("<br />" + pairs.getKey() + " = " + pairs.getValue());
//System.out.println(pairs.getKey() + " = " + pairs.getValue());
}

I did two things that may have had an impact, in the process of trying to debug what was going on I needed these further imports;
import java.util.Iterator;
import java.util.Map;
Although I'm not iterating over the hashMap, I've left them in in case which gives me the option of dumping the hashMap out to my system audit trail when application is in production. In variations of the snippet below after it started working I was able to get to any of the data I needed, even if the value was Null, and toString() also seemed to be optional again, as it made no difference to the output.
String cgiValue = "";
cgiValue = hmParam.get("ship_to_lastname").toString();
out.println("<br />Lastname: " + cgiValue);
out.println("<br />Company name: " + hmParam.get("bill_to_company"));
out.println("<br />First name: " + hmParam.get("ship_to_firstname"));
The second thing I did, while trying to get code to work was I enabled the option "Compile Java code with debugging information" for the agent, this may have done something to the way the project was built within the Domino Developer client.
I think I have to put this down to some sort of internal error created when Domino Designer compiled the code. I had a major crash last night while working on this which necessitated a cold boot of my laptop. You also may find that when using Domino Designer 8.5.x that strange things can happen if you don't completely close down all the tasks from time to time with KillNotes

Obtain a share UpdateKey from LinkedIn using LinkedIn J and getNetworkUpdates() with Coldfusion

Using the "Network Updates API" example at the following link I am able to post network updates with no problem using client.postNetworkUpdate(updateText).
http://code.google.com/p/linkedin-j/wiki/GettingStarted
So posting works great.. However posting an update does not return an "UpdateKey" which is used to retrieve stats for post itself such as comments, likes, etc. Without the UpdateKey I cannot retrieve stats. So what I would like to do is post, then retrieve the last post using the getNetworkUpdates() function, and in that retrieval will be the UpdateKey that I need to use later to retrieve stats. Here's a sample script in Java on how to get network updates, but I need to do this in Coldfusion instead of Java.
Network network = client.getNetworkUpdates(EnumSet.of(NetworkUpdateType.STATUS_UPDATE));
System.out.println("Total updates fetched:" + network.getUpdates().getTotal());
for (Update update : network.getUpdates().getUpdateList()) {
System.out.println("-------------------------------");
System.out.println(update.getUpdateKey() + ":" + update.getUpdateContent().getPerson().getFirstName() + " " + update.getUpdateContent().getPerson().getLastName() + "->" + update.getUpdateContent().getPerson().getCurrentStatus());
if (update.getUpdateComments() != null) {
System.out.println("Total comments fetched:" + update.getUpdateComments().getTotal());
for (UpdateComment comment : update.getUpdateComments().getUpdateCommentList()) {
System.out.println(comment.getPerson().getFirstName() + " " + comment.getPerson().getLastName() + "->" + comment.getComment());
}
}
}
Anyone have any thoughts on how to accomplish this using Coldfusion?
Thanks

I have not used that api, but I am guessing you could use the first two lines to grab the number of updates. Then use the overloaded client.getNetworkUpdates(start, end) method to retrieve the last update and obtain its key.
Totally untested, but something along these lines:
<cfscript>
...
// not sure about accessing the STATUS_UPDATE enum. One of these should work:
// method 1
STATUS_UPDATE = createObject("java", "com.google.code.linkedinapi.client.enumeration.NetworkUpdateType$STATUS_UPDATE");
// method 2
NetworkUpdateType = createObject("java", "com.google.code.linkedinapi.client.enumeration.NetworkUpdateType");
STATUS_UPDATE = NetworkUpdateType.valueOf("STATUS_UPDATE");
enumSet = createObject("java", "java.util.EnumSet");
network = yourClientObject.getNetworkUpdates(enumSet.of(STATUS_UPDATE));
numOfUpdates = network.getUpdates().getTotal();
// Add error handling in case numOfUpdates = 0
result = yourClientObject.getNetworkUpdates(numOfUpdates, numOfUpdates);
lastUpdate = result.getUpdates().getUpdateList().get(0);
key = lastUpdate.getUpdateKey();
</cfscript>

You can also use socialauth library to retrieve updates and post status on linkedin.

Fill fields in webview automatically

I have seen this question floating around the internet, but I haven't found a working solution yet. Basically, I want to load my app and press a button; the button action will then fill in a username and password in a website already loaded in the webview (or wait for onPageFinished). Finally, the submit button on the login page will be activated.
From what I understand this can be done by doing a java injection with the loadUrl(javascript), but I don't know what the java commands would be to fill in the fields. The same question was asked for iOS, but the commands are slightly different.
Is it possible to do what I am asking with javascript in a webivew, or do I have to do a http-post without a webview like this or this?
Thank you so much for any help you can give!

Thanks all for your answer, it helped me, but didn't work.
It was allways opening a white page until i found this :
https://stackoverflow.com/a/25606090/3204928
So here complete solution, mixing all infos found here and there :
1) first of all you have to enable DOM storage, if you don't do that, .GetElementByXXX will return nothing (you have to do it before loading the page)
myWebView.getSettings().setDomStorageEnabled(true);
2)Your last Javascript call on GetElementByXXX MUST store the result in a variable
Exemple 1 :
_webview.loadUrl("javascript:var uselessvar =document.getElementById('passwordfield').value='"+password+"';");
here only one call (only one semi-colon) so we immediatly store the result in 'uselessvar'
Example 2 : see user802467 answer
here there is 3 calls (one for login field, one for password field, one to submit button), only the last call need to be store, it's done in 'frms'
Javascript programmers should easily explain this behaviour...
hope this will help

You don't need to use "java commands"... but instead JavaScript... for instance:
String username = "cristian";
webview.loadUrl("javascript:document.getElementById('username').value = '"+username+"';");
So basically, what you have to do is a big string of JavaScript code that will get those fields and put values on them; also, you can enable/disable the submit button from JavaScript.

This worked for me to fill form values and submitting the form:
webView.loadUrl("javascript: {" +
"document.getElementById('username').value = '"+uname +"';" +
"document.getElementById('password').value = '"+password+"';" +
"var frms = document.getElementsByName('loginForm');" +
"frms[0].submit(); };");

Here is complete code which works for me (Bitbucket):
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setDomStorageEnabled(true);
webView.loadUrl("http://example.com/");
webView.setWebViewClient(new WebViewClient(){
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
final String password = "password";
final String username = "username";
final String answer = 5;
final String js = "javascript:" +
"document.getElementById('password').value = '" + password + "';" +
"document.getElementById('username').value = '" + username + "';" +
"var ans = document.getElementsByName('answer');" +
"ans[0].value = '" + answer + "';" +
"document.getElementById('fl').click()";
if (Build.VERSION.SDK_INT >= 19) {
view.evaluateJavascript(js, new ValueCallback<String>() {
#Override
public void onReceiveValue(String s) {
}
});
} else {
view.loadUrl(js);
}
}
});

I tried #user802467 solution.But there was a different behaviour in 2 things
If I stored ONLY the last javascript call in a variable, it was not filling in the fields. Instead if I stored all the three calls in variables, it did
For some reason my form was not being submitted using submit(). But instead of submitting the form, if I clicked on the submit button using button.click(), I didnot need to store all the three calls and everything worked perfectly!
Here is what I used (but didnt work)
view.loadUrl("javascript: var x = document.getElementById('username').value = '" + username + "';" +
"var y = document.getElementById('password').value = '" + password + "';" +
"var form1 = document.getElementById('loginform');" +
"form1[0].submit(); ");
Here is the code that worked for me
view.loadUrl("javascript: document.getElementById('username').value = '" + username + "';" +
" document.getElementById('password').value = '" + password + "';" +
"var z = document.getElementById('submitbutton').click();"
);

It works for me
webView.loadUrl("javascript:var uselessvar =document.getElementById('regno').value='"+mob+"';",null);
webView.loadUrl("javascript:var uselessvar =document.getElementById('passwd').value='"+pass+"';",null);

Questions method of the stackoverflow api returns only one page of questions

Trying to work with questions method of the stackoverflow api and it returns only one page of questions , how can I get the following pages?
The java code I am using :
URL stackoverflow = new URL("http://api.stackoverflow.com/1.1/"
+ method + "?" + "answers=" + includeAnswers + "&body="
+ includeBody + "&fromdate=" + fromUnixTime + "&todate="
+ toUnixTime);
URLConnection connection = stackoverflow.openConnection();
InputStream input = connection.getInputStream();
Thank you.

It says right in the documentation for the questions method :
page – The pagination offset for the
current collection. Affected by the
specified pagesize. 32-bit signed
integer
