Reasons for selection
- Perform series of comprehensive WSDL tests that verify every aspect of the WSDL document
- Test and verify client/server functionality before deployment
- Ensure the reliability, quality, security, and interoperability of Web service
- Verify data integrity and server/client functionality
- Identify server capabilities under stress and load
- Uniform test suites can be rolled over from unit testing to functional testing to load testing
- Prevent errors, pinpoint weaknesses, and stress test long before deployment
- Accelerate time to market
The winner of the contest is Java Web Service Developer Pack! Almost 50% of the voters have opted for this software suite from Sun Microsystems.
Some new and exciting features in the latest release of Java WSDP that might have influenced the voters can be the following:
Sun Java Streaming XML Parser
Java WSDP 1.5 includes an EA implementation of Sun Java Streaming XML Parser Version 1.0, a high-performance implementation of StAX, the Streaming API for XML. StAX is the standard Java based API for pull-parsing XML, which complements the existing SAX and DOM parsing models by allowing the programmer to explicitly ask for next events.
XML Web Services Security
XML Web Services Security is an implementation of the Web Services Security (WSS) specification developed at OASIS. Java WSDP 1.5 includes the following XWS-Security features:
- Support for securing JAX-RPC applications at the service, port, and operation levels
- A sample security framework within which a JAX-RPC application developer will be able to secure applications by signing and verifying parts of SOAP messages using XML Digital Signature APIs, and encrypting and decrypting parts of a SOAP message using XML Encryption APIs. The message sender also can make claims about the security properties by associating security tokens with the message. An example of a security claim is the identity of the sender, identified by a user name and password
- Sample programs that demonstrate using the framework
- Command-line tools that provide specialized utilities for keystore management and the like.
In general, the various features that might have distinguished Java WSDP from other similar Web services software can be:
- Free software
A programmer is free to try out Java WSDP without any worry about cost and get started developing Web services.
- Frequent releases
Sun has come out with new releases of Java WSDP every few months. This establishes a defined development path in the product's life cycle, as well as strong bug fixing and attending to various user requests on behalf of the parent company.
Java WSDP is a working Java programmer's product. It does not provide any colourful, heavy environment. Instead, it provides command-line utilities and supplementary material that enable a developer to write customized solutions.
- Wide range of implementations: A complete collection
Java WSDP provides a rich set of utilities for the Web services developer, with additional security tools and updated XML-related standards.
- XML Security
Java WSDP includes implementations for message-level security in Web services using XML and Web Services Security (XWS-Security), including the ability to generate and validate XML signatures using XML Digital Signatures API and encrypt and decrypt the message using XML Encryption APIs.
- Java Community
Java WSDP targets the Java developer community, which is one of the largest of its kind.
- Professional documentation, tutorials and online help
This is one area where Java WSDP scores way above many powerful open source products. The documentation is professionally done and self-explanatory, supplemented by sample programs and online tutorials.
A Brief Analysis
In a dynamic industry like software, trends change with every new invention. From the results of this contest, we can try to identify some emerging patterns in the software industry.
- Open source softwares
With two of the five finalists being open source products, we can say that there is a wide commercial acceptance of open source products. As open source software is competing professionally with commercial products, the advantage of having the source code looks more lucrative. For example, in case of any problem in Axis, the developer can take a look into the source code and is free to modify it as per the business needs.
- Free and simple enabling tools
A comprehensive, professional suite like BEA Weblogic did not feature among the finalists of this contest in which Java WSDP was adjudged the best Web services software of the year. This probably indicates that developers prefer to have free and simple enabling tools than high end, complex products that control all aspects of application development process.
- Focus on Java / J2EE
In this contest, as we see the finalists in all the various categories, there is a clear focus on Java/ J2EE . Software that is meant for Java developers caters to one of the largest developer communities.
The technology for Web services is still maturing. Standards and implementations are evolving constantly to suite the dynamic needs of the users. With an increasing commercial focus as well as a very active open source developer community in place, a wide range of new products is coming up in every area of Web services.
The selections for the Web Service of the Year 2005 contest will indicate some of the best products in the different areas of Web services among the abundance of utilities available today. This will guide the developer to find which Web services software will add the best value to a particular application.
