SE 370: Programming Web Services

Week 4: SOAP & NetBeansCopyright © Steven W. Johnson

February 1, 2013

SOAP-based web services

Nusoap

SOAP web services in:

PHP

NetBeans (Java)

This week:

2

Client has limited alternatives:

data is a single value

data is an array

data has multiple values (SOAP)

data is constants (written into the code)

data is variables (collected from a form)

Conceptual web services:

3

Server has limited number of alternatives:

simple calculation/print text (‘Hello World’)

complex calculation using many variables

writes query using variables; database

read/update operation to a table

return single variable

return an array


4


5

server

serialize de-serialize

client

Data appears as: single value array function parameters

Data collected by: constants in code dorm inputs document

Data processed: simple single calculation complex calculation prepare data as a query

Data used by: function query/database table

Data transferred as: variable array

SOAP:

6

Last week, XML-RPC; this week, SOAP

XML-RPC is the BASIC of web services

SOAP is the C of web services

Rules

Structure

Format

SOAP:

7

SOAP more verbose; more capable

SOAP is about document transfer

SOAP requires an IDE

If you like polymorphic accessors, enumerations,and orthogonal protocol binding, then SOAP is for you

SOAP:

8

SOAP adds to XML-RPC:

user-defined data types

specify recipient

message specific processing control

others

NOT (as) easy to use

Biggest advantage: customization of message

SOAP:

9

SOAP: Simple Object Access Protocol

Platform and language independent

HTTP and XML, like XML-RPC

Difference: files instead of data

Supports different protocols and formats:HTTP, SMTP, MIME

W3C recommendation (2003)

≈44 pages long (not so short)

Ways to use SOAP:

HTTP

FTP

I/O

Jabber

SMTP

POP3

TCP

MQSeries

SOAP:

10

Has three elements:

<envelope>

<header>

<body>

may include fault element

CANNOT contain a DTD reference

CANNOT hold XML processing instructions

SOAP:

11

SOAP:

12

SOAP skeleton:

<?xml version="1.0"?><soap:Envelopexmlns:soap="http://www.w3.org/2001/12/soap-envelope"soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding">

<soap:Header>...</soap:Header>

<soap:Body>... <soap:Fault> ... </soap:Fault></soap:Body>

</soap:Envelope>

http://www.w3schools.com/soap/soap_envelope.asp

SOAP:

13

SOAP header:

Optional; first child of Envelope if present

Holds application-specific information

Defines how to process SOAP message

three defined attributes to default namespace:

mustUnderstand

Actor

encodingStyle

SOAP:

14

SOAP envelope:

root element of SOAP message

holds one body element

SOAP body element: held in envelope<?xml version="1.0"?><soap:Envelopexmlns:soap="http://www.w3.org/2001/12/soap-envelope"soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding"> <soap:Header> </soap:Header> <soap:Body> <m:GetStockPrice xmlns:m="http://www.example.org/stock"> <m:StockName>IBM</m:StockName> </m:GetStockPrice> </soap:Body></soap:Envelope>

Nusoap:

15

Used with PHP; a collection of PHP classes

Allows rpc/encoded & document/literal services

Has some similarites with XML-RPC

Dietrich Ayala

‘nusoap’ is the library (collection of PHP classes)

Converts PHP into XML (SOAP envelopes)

SOAP 1.1, WSDL 1.1, and HTTP 1.0/1.1

Version 1.114 (2007)

Nusoap:

16

The process:

Nusoap:

17

Again, three files are used: client, server, library

All files placed in web folder

Nusoap:

18

www

client.php

server.php

nusoap.php (SOAP library)

Nusoap:

19

server

Nusoap

client

Nusoap

serialize de-serialize

Create ‘client.php’ in Dreamweaver:

Prints ‘Hello Scott’ to web page

Nusoap:

20

<?php require_once('nusoap.php'); $client = new nusoap_client('http://127.0.0.1/server.php'); $result = $client->call('hello', array('name' => 'Scott')); echo '<h2>Result</h2><pre>'; print_r($result); echo '</pre>';?>

Uses ‘hello’ function

Sends data

Absolute address

Create ‘server.php’ in Dreamweaver:

Nusoap:

21

<?php require_once('nusoap.php'); $server = new soap_server; $server->register('hello');

function hello($name) { return 'Hello, ' . $name; }

$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : ''; $server->service($HTTP_RAW_POST_DATA);?>

‘client’ calls ‘server’ for processing of data:

Processing function can be much more complex

Lab: Nusoap

24

<?php require_once('nusoap.php'); $client = new nusoap_client('http://127.0.0.1/server.php'); $result = $client->call('hello', array('name' => 'Scott')); echo '<h2>Result</h2><pre>'; print_r($result); echo '</pre>';?> <?php

require_once('nusoap.php'); $server = new soap_server; $server->register('hello');

function hello($name) { return 'Hello, ' . $name; }

$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : ''; $server->service($HTTP_RAW_POST_DATA);?>

SOAP best built in IDE

Our IDE: NetBeans, IDE for Java programming*

Default: UniServer isn’t Java enabled

Time for new web stack

NetBeans:

35

Programming Language

Web Server

Database

Language Engines

Operating System

NetBeans: IDE for Java programming*

Download: http://netbeans.org/downloads/

NetBeans 7.3 (64-bit) includes:

GlassFish (application & web server)

Apache Tomcat 7.0.34 (Java servlets)

NetBeans:

36

An open source IDE

Primary aim: Java

Supports:

HTML/5, PHP, C/C++, etc.

Started as a school project

Purchased by Sun

Purchased by Oracle

What is NetBeans?

37

Java Programming environment:

Java Server Pages (replaces PHP)

Tomcat

Glassfish server (Replaces Apache)

NetBeans:

38

Java Server Pages

Serves same function as .php and .asp

Java is compiled

NetBeans:

39

All three:

are server side technologies

allow scripting to be mixed HTML

require server software (compiler/interpreter)

ASP and JSP may require application server

JSP is an extension on a web page; uses servlets

PHP is a programming language; uses scripts

NetBeans:

40

Biggest differences:

strictly data typed

requires an application server (compiler)

<% %>instead of <? ?>

NetBeans:

41

<h2>Some even numbers:</h2> <% int loop = 1; for (int i=0; i<11; i+=2) { %> <p>Even number <%= loop %>: <%= i %>.</p> <% } %> <p>Done.</p>

GlassFish:

an application server

also serves web pages

open source

manages JavaEE applications

NetBeans:

42*many IDEs offer support in many programming paradigms

What’s an application server?

A server that hosts applications

PHP: interprets and then sends

appserver: runs code embedded in web pages

connect to databases

connect to middleware

provides methods clients can call

.asp and .jsp are big users

NetBeans:


What’s an application server?

NetBeans:

44

receives request

sends response

data/method calls

sends output

creates or locates htmlmethod of communication: httpinformation passed: markup

compiles executables/run processesmethod of communication: anythinginformation passed: program logic

Web Server

Application Server

Tomcat: Servlet container

Made by Apache

Open source web server

Components:

Catalina: servlet container

Coyote: HTTP connector

Jasper: a JSP engine (compiler)

NetBeans:


Compiles servlets on .jsp

Effect: like PHP interpreter for Java

NetBeans:

46

Web Server

Web Server

Servlet Container

HTTP Request

HTTP Response

Client

NetBeans 7.4 (windows) includes JDK

Start Extract:

Installing NetBeans:

47

Start Install:


48

Do lots of thinking and installing

Place shortcut in Quick Launch


49

Close start page


50

Editor good for single-file solutions

IDE good when solutions require several files

Example: C code

source code

libraries

object files

linker files

executable

IDE versus editor:

51

Projects:

Holds all files necessary for integrated solution

“A folder” holding a multi-file solution

A workspace holds many projects

Projects hold many folders/files that complete a task

IDE versus editors:

52

Create a new project: ‘test’ (.html)

NetBeans:

53

NetBeans:

54

Create a new project: ‘test’ (.jsp)

NetBeans:

55

NetBeans:

56

Right click on Project name and ‘run’

NetBeans:

57

Check your ‘Output’ panel

NetBeans:

58

Start GlassFish manually (ONLY if needed):

Services window

Right-click server node

Start

NetBeans:

59

Unblock the port for Java

SOAP web services & NetBeans:

60

Generates a blank web page (port :8080)

NetBeans:

61

Two instances of Java running (after run)

One instance of NetBeans


62

Running netstat –ao to check ports:


63

PID of ports goes to ‘big Java’


64

If GlassFish doesn’t start…

Turkish locale seems to be an issue


65

Netbeans_default_options

Add to end:


66

"-J-Duser.language=en -J-Duser.region=US"

Location of saved work:

NetBeans:

67

Holds all files necessary for integrated solution

“A folder” holding a multi-file solution

A workspace holds many projects

Projects hold many folders/files that complete a task
