do not think it can send synchronous message

I found alternate link
http://commons.apache.org/proper/commons-chain/download_chain.cgi
any end to end examples to understand this concept? please advise

hi,

i am looking at below link

http://www.onjava.com/pub/a/onjava/2005/03/02/commonchains.html

How this apache chain related to spring and rest web serives. Any good examples around this to understand end to end flow. why we need chain of beans?

when  i try to download apache chain says
http://commons.apache.org/proper/commons-chain/downloads.html

says
Not Found

The requested URL /proper/commons-chain/downloads.html was not found on this serve


please advise

i searched below link

https://github.com/jax-rs/api

can you please post exact link to get jars. What all jars i need? any end to end examples on web services?

i am trying below example
https://www.tutorialspoint.com/restful/restful_first_application.htm

when i added project to tomcat 8.5 in eclipse and trying to start tomcat i am getting below error

Server Tomcat v8.5 Server at localhost failed to start.
are these below 3 same jar or different jars?

\jaxrs-ri-2.17\jaxrs-ri\api
\jaxrs-ri-2.17\jaxrs-ri\ext
\jaxrs-ri-2.17\jaxrs-ri\lib
jaxrs-ri seems jar right which has api and ext and lib within that?

i downloaded that and added from below site
http://www.java2s.com/Code/Jar/j/Downloadjaxrsapijar.htm
it seems to have 2.0 version not 2.17 as mentioned in site?
where i can get exact version jar?
where i can see exact error trace of tomcat?

please advise

hi,

i was reading as below
https://www.tutorialspoint.com/restful/restful_statelessness.htm

what is the meaning of below

Consider the following URL −

https://localhost:8080/UserManagement/rest/UserService/users/1

If you hit the above url using your browser or using a java based client or using Postman, result will always be the User XML whose Id is 1 because the server does not store any information about the client.

<user>
  <id>1</id>
  <name>mahesh</name>
  <profession>1</profession>
</user>

how result with id 1 is related to statelessness.

since we created new user it created with id 1 and while retrieving we get same value right.

please advise

i prefer videos better

instead of  scanner.nextLine() can i use scanner.next()?
what is meaning of nextLine() method here?
i am entering input like
23192
etc in the same line right not next line?

sure. I will do that

int[] digits = Arrays.stream(stringDigits.split("")).mapToInt(Integer::parseInt).toArray();

in above code what is ::

i never seen such operator? please advise

i never remember creating unchecked exception myself

i failed twice before i pass earlier

Saisir les chiffres: 1384
  1
 333
44444
8888888

i am able to see output.

I never saw a method returning its own class object? any other similar use cases or links or examples where method returns its own class object? it looks bit odd as i am familiar with returning String int etc mostly

import java.util.Arrays; import java.util.Scanner; public class App {        private String stringDigits;    private int[] digits;        public App readDigitsAsUserInput()    {        Scanner scanner = new Scanner(System.in);        System.out.print("Saisir les chiffres: ");        this.stringDigits = scanner.nextLine();        scanner.close();        return this;    }        public App createArrayOfDigits()    {        this.digits = Arrays.stream(stringDigits.split("")).mapToInt(Integer::parseInt).toArray();        Arrays.sort(digits);        return this;    }        public void displayPyramid()    {        int marginLeft;        for(int i = 1; i <= this.digits.length; i += 1) {            marginLeft = this.digits.length - i;            for(int j = 0; j < marginLeft; j += 1) {                System.out.print(" ");            }            for(int j = 0; j < i; j += 1) {                System.out.print(this.digits[i-1]);            }            for(int j = 0; j < i-1; j += 1) {                System.out.print(this.digits[i-1]);            }            System.out.println();        }    }        public static void main(String[] args) {        new App().readDigitsAsUserInput().createArrayOfDigits().displayPyramid();    } }

i wonder why the method returns App like below

public App createArrayOfDigits()


i do not see any output. How to execute this program in eclipse?

Hi,
