1. SE 370: Programming Web Services Week 4: SOAP & NetBeans Copyright © Steven W. Johnson February 1, 2013

2. SOAP-based web services Nusoap SOAP web services in: PHP NetBeans (Java) This week: 2

3. 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

4. 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 Conceptual web services: 4

5. 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

6. 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

7. 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

8. 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

9. 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)

10. Ways to use SOAP: HTTP FTP I/O Jabber SMTP POP3 TCP MQSeries SOAP: 10

11. Has three elements: may include fault element CANNOT contain a DTD reference CANNOT hold XML processing instructions SOAP: 11

12. SOAP: 12 SOAP skeleton:......... http://www.w3schools.com/soap/soap_envelope.asp

13. 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

14. SOAP: 14 SOAP envelope: root element of SOAP message holds one body element SOAP body element: held in envelope IBM

15. Nusoap: 15 Used with PHP; a collection of PHP classes Allows rpc/encoded & document/literal services Has some similarites with XML-RPC Dietrich Ayala

16. ‘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

17. The process: Nusoap: 17

18. 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)

19. Nusoap: 19 server Nusoap client Nusoap serialize de-serialize

20. 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 = $client->call('hello', array('name' => 'Scott')); echo ' Result '; print_r($result); echo ' '; ?> Uses ‘hello’ function Sends data Absolute address

21. 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); ?> if

22. Lab: Nusoap 22 POST /server.php HTTP/1.0 Host: 127.0.0.1 User-Agent: NuSOAP/0.7.3 (1.114) Content-Type: text/xml; charset=ISO-8859-1 SOAPAction: "" Content-Length: 500 <SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"> Scott Request: header/xml generated by ‘client’

23. Response: header/xml generated by ‘server’ Lab: Nusoap 23 HTTP/1.1 200 OK Date: Fri, 15 Mar 2013 13:38:22 GMT Server: Apache/2.2.16 (Win32) mod_ssl/2.2.16 OpenSSL/0.9.8o PHP/5.3.3 DAV/2 X-Powered-By: PHP/5.3.3 X-SOAP-Server: NuSOAP/0.7.3 (1.114) Content-Length: 518 Vary: User-Agent,Accept-Encoding Connection: close Content-Type: text/xml; charset=ISO-8859-1 <SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"> Hello, Scott

24. ‘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 = $client->call('hello', array('name' => 'Scott')); echo ' Result '; print_r($result); echo ' '; ?> <?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); ?> “Scott” $name = “Scott”

25. Copy/paste ‘nusoap’ into your web server Fix the URL, change name to your name Open page: localhost/nusoap/client.php Lab: Nusoap 25

26. Copy/paste ‘dice’ into your web server Holds: client server library 6 images of a die (zar) Lab: Dice 26

27. Working page: Lab: Dice 27

28. Code required (server): ignore the passed variable (eliminate??) return is an array, must define random number generator: (returns int) Lab: Dice 28 mt_rand(1,6);//more efficient rand(1,6); $client->call('hello'); $result = []; 3.png 125px x 125px

29. Code required (client): function arguments = parameters remove messages add form, images, text output Lab: Dice 29.png" width="125" height="125">

30. Done! Lab: Dice 30

31. Client code (PHP): Lab: Dice 31 <?php if(isset($_POST['button'])) { require_once('nusoap.php'); $client = new nusoap_client('http://127.0.0.1/dice/server.php'); $err = $client->getError(); // Check for an error if ($err) { echo ' Constructor error '. $err. ' '; } $result = $client->call('hello'); } ?>

32. 32 table { margin-left: auto; margin-right: auto; }.png" width="125" height="125">.png" width="125" height="125"> Your spin = <?php echo $result[0] + $result[1]; ?>

33. Server code (PHP): Lab: Dice 33 <?php // Pull in the NuSOAP code require_once('nusoap.php'); // Create the server instance $server = new soap_server; // Register the method to expose $server->register('hello'); // Define the method as a PHP function function hello() { $result = []; $result[0] = mt_rand(1, 6); $result[1] = mt_rand(1, 6); return $result; } // Use the request to (try to) invoke the service $HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : ''; $server->service($HTTP_RAW_POST_DATA); ?>

34. Break 34

35. 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 DatabaseDatabase Language Engines Operating System

36. 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

37. 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

38. Java Programming environment: Java Server Pages (replaces PHP) Tomcat Glassfish server (Replaces Apache) NetBeans: 38

39. Java Server Pages Serves same function as.php and.asp Java is compiled NetBeans: 39

40. 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

41. Biggest differences: strictly data typed requires an application server (compiler) instead of NetBeans: 41 Some even numbers: <% int loop = 1; for (int i=0; i Even number :. Done.

42. GlassFish: an application server also serves web pages open source manages JavaEE applications NetBeans: 42 *many IDEs offer support in many programming paradigms

43. 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: 43 *many IDEs offer support in many programming paradigms

44. What’s an application server? NetBeans: 44 receives request sends response data/method calls sends output creates or locates html method of communication: http information passed: markup compiles executables/run processes method of communication: anything information passed: program logic Web Server Application Server

45. Tomcat: Servlet container Made by Apache Open source web server Components: Catalina: servlet container Coyote: HTTP connector Jasper: a JSP engine (compiler) NetBeans: 45 *many IDEs offer support in many programming paradigms

46. Compiles servlets on.jsp Effect: like PHP interpreter for Java NetBeans: 46 Web Server Servlet Container HTTP Request HTTP Response Client
