  • 'Bob Lee heavily involved' (slide 42), huh ?

    Bob wrote a couple of weeks ago on the guice-dev mailing list that he stopped being involved in JSR299 a year ago:

    'If 299 looks superficially like Guice, it's because I was heavily involved.
    I left the EG over a year ago because I disagreed with the leadership and
    technical direction.

    So far, I haven't bothered to actively oppose 299 for a few reasons:

    1) 299 doesn't seem to have gained any real traction. Only RedHat is
    pushing it. You've heard of design by committee? 299 is design by Gavin. :-)

    2) 299 is part of EE, which we don't use or care much about. I think the
    risk of 299 imposing itself on SE is zero.

    3) I choose to spend my time constructively (on the Java language, Guice,
    JSR 166, Android, etc.), not playing political games.

    My advice to our users is to continue using the Guice API. Your code will be
    more maintainable as a result. JSR 299 does not represent consensus. It's a
    land grab by unqualified vendors who would rather prematurely set an
    unproven design in stone than compete on a level playing field. It's EJB and
    JSF all over again. By comparison, the Guice API has enjoyed many times the
    scrutiny by people who actually use and understand this stuff. Guice is
    simpler, better specified and more future proof as a result.

    In other words, Guice will not directly support 299, but you could easily
    build a 299 extension for Guice. You'd be better off sticking to the Guice
    API though.

    Bob'

    • GlassFish Technical Overview May 2009 1
    • What Is GlassFish? • A Java EE 5-compliant Application Server > Can run J2EE applications too • Open Source > CDDL (like OpenSolaris, NetBeans) > GPLv2 (like Java and NetBeans) • Enterprise Quality > GlassFish Enterprise Application Server > Adds support, indemnification, and 99.999% availability

    • What is Application Server? • An application server is a server that hosts APIs to expose business logic and business processes for use by third-party applications. • It provides an n-tier architecture • Often referred to as an J2EE application Server
    • Application Server flavors? • WebSphere Application Server and WebSphere Application Server Community Edition (IBM), Sybase Enterprise Application Server (Sybase Inc), WebLogic Server (BEA), JBoss (Red Hat), JRun (Adobe Systems), Apache Geronimo (Apache Software Foundation), Oracle OC4J (Oracle Corporation), Sun Java System Application Server (based on GlassFish Application Server)(Sun Microsystems), SAP Netweaver AS (ABAP/Java) (SAP), and Glassfish Application Server.
