SAN CARLOS, CA — July 22, 2008 — Mark Logic® Corporation, provider of the industry’s leading XML content platform, today announced that MarkMail, a free service for searching mailing list archives available at http://markmail.org/, has added group messages from the highly influential java.net community. In cooperation with CollabNet, the leading provider of solutions for distributed software development and the system that powers http://java.net, more than 975,000 emails were loaded into the MarkMail system. The java.net community members now have the ability to seamlessly query across the structured and unstructured parts of email, including attachments, and unlock the tremendous value embedded in these messages.

Founded in 2003, java.net is the realization of a vision of a diverse group of engineers, researchers, technologists and evangelists at Sun Microsystems, Inc. (NASDAQ: JAVA) to provide a common area for interesting conversations and innovative development projects related to Java technology. With nearly 450,000 total members, java.net encompasses a wealth of community-based knowledge in its ongoing email discussions, which most recently totaled 40,000 emails per month as shown by the following MarkMail histogram:

“Wow – the features in MarkMail are cool and you quickly get the feeling it is just the tip of the iceberg,” said Marla Parker, community manager for java.net, in a recent blog post. “To assist users, we plan to create a page on java.net with a bunch of sample queries and instructions on how new active mailing lists on java.net can get added to the MarkMail archive.”

MarkMail was launched in November 2007 with four million messages from the Apache Software Foundation. Since the site’s unveiling, MarkMail has garnered rave reviews from both the community and industry watchers, and continues to add content relevant to a wide breadth of software developers. Today, MarkMail hosts more than 16 million messages across 3,800 mailing lists, including umbrella communities such as Apache, Codehaus, Mozilla, and the World Wide Web Consortium, technology-specific communities such as Eclipse, GNOME, KDE, MySQL, NetcoolUsers, Perl, Python and Xen, and a broad spectrum of other projects.

“I've been working with Java for over a decade now and it's really gratifying both personally and professionally to be able to bring MarkMail’s advanced search and discovery capabilities to the java.net community – to projects such as GlassFish, jMaki, AppFuse, Grizzly, Hudson and WebWork,” said Jason Hunter, principal technologist for MarkMail at Mark Logic Corporation. “Having the java.net list archives available in MarkMail will help speed project development, make it easier for users to find answers, and make it possible to track what's happening across thousands of lists for the first time.”
