But while searching i came across 2 different implementation.. One is this and other is this , where httpget is used..
So are these same ? When we talk about Restful, is the 2nd implementation valid ?
how to implement the Rest API which is like "URL...". And how to implement in Java where the class extends ServerResource.
View Replies View RelatedHow can i count using JsonPath? See this json -
[
{
"total": 4414,
"userName": "Tom",
},
{
"total": 6608,
"userName": "Jerry",
},
{
"total": 5,
"userName": "Tom",
}
]
I want to count userName "Tom" so the answer will be 2 and counting "Jerry" will produce 1
Running the following says i have the value inside but how much of it.
assertThat(jsonPath.getList("userName", String.class), hasItem("Tom"));
Running this says the size of the list but the list may contain other values than "Tom", Like "Jerry"
assertThat(jsonPath.getInt("size()"), equalTo(3));
is this can be answered within JsonPath or i must use FOR, LOOPS, else ?
"citizen":{"name":"John", "gender":"M","age":32}
Now, I only want to change age to 35, which method should I use and how should the payload/URL look like to be RESTful?
URL....my file name can contain special characters but when I passing this file name as a parameter in URL using REST.I am getting exception.

Are the WebDAV extensions related to REST principles? What I mean by that is, REST is an abstraction of the WWW architecture and the WebDAV is just an extension to the HTTP. So can we say that when I speak in terms of REST API's, I can restrict myself to HTTP and not HTTP extensions like WebDAV?
View Replies View RelatedI hope this is the right forum. My question is about REST interceptors. I've got the code:
package edu.psu.swe.fortress.poc.interceptor;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
import javax.enterprise.util.Nonbinding;
import javax.ws.rs.NameBinding;

The output from the debug show that permissions values inside of the ResourceImpl contains the values I'd expect (foo,bar), but inside the interceptor, they're missing. Is there a way to get the arguments in ResourceImpl to pass through to the interceptor?
Log output looks like:
15:59:55,223 INFO [stdout] (default task-9) @edu.psu.swe.fortress.poc.interceptor.FortressProtected(permissions=[])
15:59:55,229 INFO [stdout] (default task-9) @edu.psu.swe.fortress.poc.interceptor.FortressProtected(permissions=[foo, bar])
I want to write one REST client program for POST request ,request and response is in JSON Format.
public String getAck() {
HttpURLConnection httpConnection = null;
URL url=null;
try {
url = new URL("http://test:8080/ils/main");
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
[Code]....
Line OutputStream os = httpConnection.getOutputStream();
I am getting connection time out problem
I have 2 war in 1 EAR.
War A corresponds to UI
War B corresponds to Rest
1) From War A, I login to the application and then fetch some users that is a rest call. I get the response back from rest in json form that ui consumes and display the data on page.
2) Now I click on the logout link from ui jsp. This logs out the session from Ui. I use <form data-dojo-type="dijit/form/Form" based logout.
3) I then go to the proxy (using burp) and manually request the rest call which I made in step no 1), the rest gives the response back with the same json object returned in step no 1) This shows that the logout action on step 2) is invalidated the session from War A (ui war) but the session or cookie based from WAR B (rest war) is not invalidated.
Expected outcome:After I Logout from War A(ui war), the session must also get invalidated from war B (rest war) and manually request from proxy should not get the same response object as received in step 1)
I'm not sure if that's the right place to ask
But I am a bit confused:
I know that JDK means "Java Development Kit" , but isn't Eclipse the same thing? (so why it's called "IDE"?)
Or maybe Eclipse is a type of JDK?
Or actually JDK and Eclipse are 2 different things

View Replies View RelatedI have been tasked with creating an invoice (school assignment). Part of the calculations is creating an interest depending on the amount of days between the current date entered, and invoice date entered (The program prompts the user to enter both the current and invoice dates by asking for the day, month and year).
We are also supposed to set the contructor to a default date of 1/1/1900.. but I don't know how or where to code that.
How to calculate the difference between the CurrentDate and Invoice. I have displayed the dates to the user as follows.
public void displayDate() {
System.out.println("
Today's Date: " + month + "/" + day + "/" + year);
}
public void displayInvDate() {
System.out.println("
Invoice Date: " + invMonth + "/" + invDay + "/" + invYear);
I have just begin to understand collections in Java. I read about the differences between LinkedList and ArrayList but have several doubts on it. I have mentioned them below
1) Why retrieving in ArrayList is faster then LinkedList?. Since both have the get method how does performance differ?.
2) How does re-sizing happens internally in ArrayList when a item is added or removed?. How slow this is compared to the pointer re-shuffling in LinkedList when a item is added or removed?.
I read that InputStream is used for byte based reading it reads 1 byte at a time.And InputStreamReader is used for charcter based reading so it reads one charcter at a time so no need to convert this first to int then read it.Here is reading using InputStream.
input=new FileInputStream("D:/input.txt");
int c;
while((c=input.read())!=-1)
{
System.out.print((char)c);
}
and here is reading using InputStreamReader
input=new FileInputStream("D:/input.txt");
reader=new InputStreamReader(input,"UTF-8");
int c;
while((c=reader.read())!=-1)
{
System.out.print((char)c);
}
so what is difference between InputStream and InputStreamReader in both case i have to use a Int and then read it and at the end if I want to print that data I have to cast that with "(char)c".So what is advantage of using InputStreamReader?

View Replies View RelatedCan explain difference between applet and application?
What are differences in code? How to write application?
What are differences in use? I looked for some answers, but I can't understand what they are talking about.
For example:
Application:
Called as stand-alone application as application can be executed from command prompt
Applet:
Requires some third party tool like a browser to execute
But... While I export applet in exclipse I can use it without any browser, just like application(as I and avarage user knows it).
Ok, I understand difference like "Applets cannot read from or write to hard disk files."
So. What should I use while creating what?
For example, something as simple as windows calc, some 2d simply platformer, some more expanded app, like idk, spotify or media player or whatever?
Since after update 51 of java web applets are nearly useless(as I know, maybe I'm wrong?), what is better?
Can application have GUI or it is only applets thing(stupid question?)?
Where can I find any application tutorial? Everything that I found was for applets. Why?
I know that oracle has released a statement saying that JavaFX will eventually replace Swing. What is the advantage of JavaFX? The new format, using "stage" instead of JFrame, seemed weird. Why is this change necessary? What benefit do we reap from JavaFX that Swing does not have?
