Course Description:

'' the developing java web services course provides business component and client developers with the information they need to design, implement, deploy, and maintain web services and web service clients using java technology components and the java 2 platform, enterprise edition (j2ee platform) platform.



the students perform the course lab exercises using the netbeans integrated development environment (ide).



who can benefit



students who can benefit from this course are business component and client developers who are interested in incorporating web service technology in java and j2ee platform applications.



prerequisites


implement and deploy a j2ee platform application containing web and enterprise javabeans (ejb)-tier components
assemble, deploy, and test a distributed java platform technology application
use the ant build environment (or other tool sets required by the labs)
describe the steps required to design and architect an enterprise application


delegates will learn how to


implement a web service using java technology components
implement a j2ee platform web service
implement a web service client that accesses the functionality provided by a j2ee platform web service

module 5 �simple object access protocol (soap)



describe the function of soap in the web services architecture

describe the structure of a soap message and the function of each primary soap element

describe the characteristics of the internet transport protocols commonly used to transmit a soap message

describe the information models available when creating soap-based web services

describe the techniques for encoding information within the body of a soap message

describe the function of the soap with attachments specification

list the pros and cons of using soap as a message format and describe an alternative architecture for transmitting xml-based information between applications



module 6 �soap with attachments api for java (saaj)



describe the function of the classes, interfaces, and methods contained in saaj

describe the relationship between saaj and dom and the impact this has on a web service developer

create and manipulate a soap message using the classes, interfaces, and methods contained in saaj

create and manipulate a soap message with attachments using the classes, interfaces, and methods contained in saaj

describe how to manage namespaces included in a soap message using saaj



module 7 �web services description language (wsdl)



describe the role that an interface description language (idl) plays in a distributed computing environment

describe the role that wsdl plays in the web service model and the primary elements contained in a wsdl file

describe the role of extensibility elements used in a wsdl file

compare the use of wsdl in document-style and remote procedure call (rpc)-style services



module 8 �the service registry



describe the purpose of a service registry

define the two types of service registries

describe the purpose of extensible markup language (ebxml)

describe the purpose of universal description, discovery, and integration (uddi)

describe the data structures defined in uddi

describe the api exposed to the client by uddi implementations

describe the purpose of the java api for xml registries (jaxr)

use the jaxr api to access a uddi registry

use jax-rpc toa message handler that processes the contents of a soap message header

describe how jax-rpc supports j2ee components as web services

describe the session support mechanism provided by jax-rpc

describe the types of web service clients that you can use with jax-rpc and the criteria that you should use to determine the type of client most appropriate for accessing a given service



module 11 �security



describe some of the security issues relating to web services and the basic techniques that you can use to address some of these issues

describe the function of public- and private-key encryption and digital signatures when implementing a security solution for an enterprise application
