Officials at Sun, Javalobby and Infravio last week revealed initiatives in Java development or web services.
The Sun-led Netbeans open source tools project released an early version of a profiler tool for troubleshooting. A Sun official said that Netbeans remains Sun's open source platform of choice, even though the company had been a subject of speculation that it would participate in the rival Eclipse open source program.
The Netbeans Profiler is an integrated CPU and memory profiler offered as a free add-on to the Netbeans 3.6 IDE. It detects issues such as performance problems and memory leaks.
"What this allows you to do is troubleshoot the performance of your application in the same IDE you develop your application," said Larry Baron, senior product manager for Netbeans at Sun.
The early release, intended for user testing, will be followed by a beta upgrade when Netbeans 4.0 is released in December. The production version of Profiler is due with Netbeans 4.1 in early 2005. Version 4.1 will focus on adding Java development capabilities such as Enterprise Javabeans.
Despite overtures during recent months that Sun might join the rival Eclipse tools initiative, the status quo remains, according to Baron. "Right now there are no plans [to join Eclipse]. It is difficult for me to comment on the future. The future has to play itself out," Baron said.
Meanwhile, Javalobby last week unveiled JDocs, which is a centralised database of Java documentation (www.jdocs.com). Javalobby is an online community of Java developers with more than 150,000 members (www.javalobby.org).
Java APIs and libraries are available, such as Java 2 Standard Edition, Eclipse, Hibernate, Java Server Pages and Apache Jakarta, said Rick Ross, president of Javalobby.org.
"We are willing to host all APIs so that every developer has a one-stop shop," Ross said. The site also includes functions for asking and answering questions.
"We think it will help increase developer productivity, help people solve problems and allow them to share their insights," said Ross.
In September Infravio plans to release an upgrade to its X-registry directory software for registering web services, adding conformance testing features to make sure web services are being used properly, said Jeff Tonkel, chief executive and president of Infravio.
Additionally, the upcoming 4.5.2 release of X-registry boosts its governance function, which provides a process model for requesting, authorising and authenticating use of web services. Improvements will be made to process flows and security, Tonkel said.
X-registry is based on the UDDI standard for web services directories and provides a way to catalogue services where consumers can shop and request their use. Authorisation is also featured. "X-registry is more like a marketplace for finding and using web services," Tonkel said.
"The web services industry is still in its early days and there is a lot of interest in service-oriented architectures and in web services as a fundamental part of creating an SOA, and people are doing their early projects," Tonkel said.
"We are hoping that in a couple years it will be rolling out, but [now] it is one project at a time," he said.
