Currently, Ron is the Spec Lead of JSR 351, Java Identity API. His participation in the JCP program was in response to specific technical needs. He says, "The chartering of JSR 115 and of JSR 196, and thus my involvement with the JCP program, were the result of a security summit that we convened in Burlington, MA ... to identify a security road map for Java (especially EE). One prominent item on the resulting road map was the need for standard container interfaces so that Java EE containers could be integrated with enterprise authentication and authorization systems." With Ron Serving as Spec Lead, JSR 115, Java Authorization Contract for Containers (2001), and JSR 196, Java Authentication Service Provider Interface for Containers (2002) , were chartered to deliver the corresponding Java APIs.

Ron communicates with the JCP and Java.net membership through the public web site of the JSR 351 RI, which is known as Project Nobis. He holds an MS in Computer Science from the University of Connecticut and a BS in Biology from Bates College. From his home in the greater Boston area, Ron coaches youth baseball and enjoys kayaking and skiing with his wife and kids.

Over the years, Rajiv has had a substantial impact on numerous JCP projects. He says, "Being part of the Java EE team since the very first release, and experiencing how the team came together to build the platform that would eventually be the foundation of how enterprise software was going to be developed, I have just loved working on the various aspects of the platform. I was particularly interested in the Web related areas, and have focused on the various specifications in that area." He is currently the Spec Lead for JSR 340, Java Servlet 3.1 Specification. He is the Maintenance Lead for several JSRs that were his original proposals, including JSR 315, Java Servlet 3.0 Specification, and JSR 250, Common Annotations for the Java Platform. He also had a leading role in JSR 5, XML Parsing Specification; JSR 63, Java API for XML (JAX) Processing 1.1; JSR 67, JAX Messaging; JSR 154, Java Servlet 2.4 Specification; and JSR 224, JAX-Based Web Services (JAX-WS) 2.0.

Rajiv earned a BE degree in Computer Engineering, 1996, from the Pune Institute of Computer Technology (PICT), which is affiliated with the University of Pune in Pune, India. His first job out of college in 1996 was working on a product that was built entirely in Java, a platform he has embraced ever since. He blogs occasionally. With patents pending, Rajiv now lives in the San Francisco Bay Area of California, where he loves to bike and play volleyball.

"Prior to working with Java, I had worked extensively with ASP 3.5, and was looking for a more maintainable solution, which would allow us to extend the team beyond me. Java's typesafety was a big draw," Pete says. "Combined with Seam, which offered an end-to-end solution to building web applications, Java was the one for me." He is driven to improve developer usability and productivity with the Java EE stack, on JBoss solutions such as JBoss AS.

Traveling from his home in Edinburgh, Scotland, Pete speaks often at JUGs and conferences such as Devoxx, JAX, JSFDays, JBoss World, and the Greater Indian Developer Summit (GIDS) in Bangalore. He has posted some of his presentations on Vimeo (search for Pete Muir), such as his talk on "The Programming Model for EE6." At JavaOne conference 2011, Rick Hightower of InfoQ gave Pete an opportunity to talk about his favorite topic: CDI architecture, as compared to Spring and Guice, and that interview is published here. Pete tweets @plmuir and blogs about Seam, Weld, and Java here.

Pete received an MSc with Distinction in Informatics, specializing in systems and software engineering, and relational and scientific databases, from The University of Edinburgh (2005), which followed his earning a BSc in Physics from Imperial College London (2003).

In 1999, David began working with Java technology after the decision was made to adopt the Java platform for Day's entire suite of products. Since then, he has worked as a solution and product architect primarily on server-side web projects, participating in numerous highly visible website content management projects for the world's largest organizations. He has shared his expertise with the OASIS standards organization, and by 2001, he had joined the JCP program, where he soon became Spec Lead for JSR 170, Content Repository for Java Technology API. As soon as that effort wrapped up, he became Spec Lead for the next version, JSR 283. He is now Spec Lead of JSR 333, Content Repository API for Java Technology 2.1. The RI and TCK for JSR 333 are being developed as open source under the Apache Jackrabbit Project and through Java.net for JSR 170, JSR 283, and JSR 333. (The package space of JSRs 170, 283, and 333 is javax.jcr, hence the use of codename JaCkRabbit.)

David remains enthusiastic about content repositories, noting that they may be "the best of both worlds between relational databases and file systems." Features include transactionality and query using SQL from the relational database world as well as support hierarchies and dealing with large binary streams that are known from filesystems. He says, "A standardized content repository is the ideal store for almost any Java application." Twice, while he was working on content repositories, the JCP community nominated David Most Outstanding Java SE/EE Spec Lead (2009, 2005), and the PMO named him a Star Spec Lead. His technical prowess also landed him a guest appearance on Adobe MAX TV 2010 to talk about the multi-screen aspect of customer experience management. And although he is nowhere near the end of his career, Best of Swiss Web 2008 honored him with a Lifetime Achievement award.

David regularly updates his content in the form of Twitter posts and slideshows, all collected at Slideshare. Or sign up for his Tweets directly @davidnuescheler. David lives in Basel, Switzerland.

From the University of Texas at Austin, Paul received a BS in Computer Science (1997), where he first encountered Java in a compilers class and wrote a Java compiler based on the language specification. From then on, he was hooked on Java. He now lives in the San Francisco Bay Area, California. His pastimes are sailing, scuba diving, and cooking.

Ronald represents IAIK in serving as Spec Lead for JSR 321, Trusted Computing API for Java. JSR 321 is the Java specification that allows software developers to access a hardware Trusted Platform Module (TPM) and provides them with a compact, high usability interface. It is based on the functionality of the TPM Software Stack specification of the Trusted Computing Group. Related lab exercises were used in European Trusted Infrastructure Summer School (ETISS) and published in academic workshops and Wiley's Software: Practice & Experience journal. Ronald and his Expert Group, which includes academicians and individual members, have been fully committed to developing and maintaining the now-released standard with as much transparency as possible. The JSR 321 page on the jcp.org site propels readers to a second website, where people can participate in the development and access the latest drafts of the source code.

The JCP community nominated JSR 321 Most Innovative JSR in 2011. The previous year, Ronald was named Outstanding Spec Lead, with the comment, "With his passion and continuous effort he not only brought JSR 321 to EDR stage despite a more than challenging time, but he also inspired companies to adopt the JSR and implement against it already." He had also been nominated for the Most Outstanding Java SE/EE Spec Lead award the year before.

Ronald's work has been published as proceedings of numerous professional conferences, in articles of journals including Journal of Supercomputing, and through live presentations all over the world (Austria, France, Germany, Hungary, China, Korea, and the United States). Ronald is fond of globe-trotting, skiing, history, and electronic music.
