What is the IBM Emerging Technologies Toolkit (ETTK)?
The ETTK is a software development kit for designing, developing, and executing emerging autonomic and grid-related technologies and Web services. The ETTK provides an environment in which to run emerging technology examples that showcase recently announced specifications and prototypes from IBM’s emerging technology development and research teams. In addition, it provides introductory material to help developers easily get started with development of autonomic technologies, Web services, and grids. The ETTK evolved from the package known as the Web Services Toolkit (WSTK). With the renaming of the WSTK package to ETTK, the scope of technologies included within the package has been expanded. The new toolkit consolidates related technologies from various IBM development and research labs. The demos and functions of the ETTK run on both Linux and Windows® operating systems.
How does it work?
The basic software components needed to experiment with and create Web services and autonomic and grid-related programs are provided with the ETTK. Included is an architectural overview of autonomic technologies, Web services, sample programs, utility services, and some tools (such as ReGS Autonomic Logging demo, XML Parser, UDDI client APIs) that are helpful in developing and deploying autonomic and grid programs and Web services. The toolkit also includes a fully-functioning SOAP and grid infrastructure.

ETTK includes a fully-functioning SOAP engine (Apache AXIS), and grid (Globus ToolkitTM) infrastructure.

da IBM un comodo tool on-line per analizzare i WDSL dei webservice a cui vogliamo accedere.
Ps. funziona solo con Internet Explorer causa uso massiccio di DHTML e JS. :(

OptimalGrid for Linux — autonomic computing on the Grid — OptimalGrid aims to simplify creating and managing large-scale, connected, parallel grid applications. It optimizes performance and includes autonomic grid functionality. OptimalGrid manages partitioning, problem piece deployment, runtime management, dynamic level of parallelism, dynamic load balancing, and even system fault tolerance and recovery. This article shows you how the OptimalGrid system is designed to bring the immense potential of Grid computing easily within reach of developers who aren’t grid infrastructure experts. Go here to get the free OptimalGrid download.

JSR sarà strettamente integrato a PHP! :D
Scripting Pages in JavaTM Web Applications :

There are a number of scripting languages that are being used today to generate dynamic content; notable examples include PHP, ECMAScript, Active Server Pages and others. Application developers using these technologies would like a standard mechanism to access information developed in the Java platform. This Specification will describe how to write portable Java classes that can be invoked from a page written in an scripting language, including details on security, resources and class loader contexts. The specification will cover both the case where the Java clases are instantiated in a Java Servlet container and the case of a Java VM. The specification may include a Java API that can be used, possibly through JNI, by an scripting language engine to access the desired Java objects. The specification will also describe how to package these scripting pages and Java classes, including how to bundle the scripting pages into a WAR file.

The way Java objects are represented and accessed in a given scripting language is specific to that scripting language but we expect this specification to indicate some common requirements for these mappings. The specification will be grounded in some specific mappings, which may or not be included as part of the specification.

il w3c ha rilasciato le specifiche ufficiali di SOAP 1.2. Questa release sarà a detta degli autori:

SOAP Version 1.2: cleaner, better Web integration, more versatile, faster.

* Cleaner: clear processing and extensibility models, increased interoperability.
* Better Web integration: better integration with XML standards and the architecture of the Web.
* More versatile: binding framework providing protocol independence.
* Faster: based on XML Infoset allowing performance optimization.

Creare classi per la gestione di database non è mai stato più facile! Grazie a daoGen sarà possibile creare e gestire un db in maniera semplice ed efficiente. Lo script, una volta immesse le specifiche del db ci creerà 4 file: il primo contentente la struttura SQL-compliant delle nostre tabelle, il secondo contenente una classe per la gestione delle tabelle ed il terzo ed il quarto tutte le funzioni per accesso (in DAO) alle nostre risorse.
Inoltre, chicca finale, daoGen supporta sia la creazione di classi PHP che Java.
