Introduction

• What’s UDDI

• Searches in UDDI

• UDDI Distributions and flavours

• Commercial Implementation vs Open Source

• Discussion WS-Talk and UDDI

What’s UDDIUniversal Description Discovery and Integration is de facto

standard web services catalogue. It consists of a directory wherebusiness can register and search for web services, centredaround a WS interface described by a WSDL document.

It is based on a set of specifications (OASIS standard) withpublic and private implementations and providing two webservices:

Inquiry : provide functions such as find_business, get_businessDetails

Publisher : provide functions such as save_business,delete_business

All these operations are based in SOAP messages.

Searches in UDDIThree can of searches can be performed using UDDI registry:

• White pages search: returns basic information such as address, contact, and identifiers about a company.

• Yellow pages search: retrieve information according to industrialcategorization and taxonomies, such as NAICS, ISO3166,and UNSPSC

• Green pages service search: retrieve technical information about Web service, as well as information about how to executethese services.

Open Source ImplementationsApache.org, JUDDI, http://ws.apache.org/juddi/

･Open Source and Platform Independent･Supports for JDK 1.3.1 and later･UDDI version 2.0 compliant implementation･Use with any relational database that supports ANSI standard SQL

(MySQL, DB2, Sybase, JDataStore, HSQLDB, etc.)･Deployable on any Java application server that supports the

Servlet 2.3 specification (Jakarta Tomcat, JOnAS, WebSphere, WebLogic, Enterprise Server, JRun, etc.)

･jUDDI registry supports a clustered deployment configuration.･Easy integration with existing authentication systems

UDDI Browser, http://uddibrowser.org/Still early version but gives a GUI to work from the client point of viewover different UDDI repositories

Open Source ImplementationsAPIsUDDI4J.org, http://uddi4j.sourceforge.net/

UDDI4J contains an implementation of the client side of UDDI from which theapplication needs to publish, find, and to bind a Web service. It also includes the source of the code, the complete JavaDoc documentation, and sample applications.

SOAP:LITE, http://sourceforge.net/projects/soaplite/ or http://soaplite.com/Collection of Perl modules that provides a simple and lightweight implementation of SOAP, XML-RPC, UDDI and other webservice-related spec.

PHPUDDI, http://phpuddi.sourceforge.net/Stand-alone PHP classes with no external dependencies, supporting basicUDDI inquiry APIs. However, not able to publish documents. Not as relevantas those above.

Find_plublisher

Populating JUDDI serverTwo methods were tried

• Produce a piece of source code to insert records like UDDI4Jor SOAP:LITE.– Development effort needed.

• Insert records directly into the DB using MySQL. The easiestoption.– DB reverse engineering needed to understand data structure.

JUDDI Advantages

• Free and Open Source

• It works

• Supports a variety of Data Bases

• Can be deployed in any Servlet container that supports spec. 2.3

• Clustering method can be used to integrate different JUDDI

JUDDI Problems

• Poor documentation, just an e-mail list is available

• Could be a little tricky to make it work at thebeginning. But we got that documented

• UDDI spec. 2 is supported at the moment

UDDI Browser

Open questionsWhich UDDI version? JUDDI supports UDDI standard version 2, but currently the

specification is v. 3.V. 3. Specifies a series of UDDI flavours.

Corporate/private: internal registry behind a firewallAffiliated: controlled environment where limited access is grantedPublic: open registry

UDDI in WS-Talk? Are we going to use a single centralised repository, or a set ofdistributed ones. The solution for this may be in the use of ActiveBPEL engine.

Others issues?
