Java EE 6 & GlassFish v3: Paving the path for the future - Tech Days 2010 India

  1. 1. <Insert Picture Here> Java EE 6 & GlassFish v3: Paving the path for the future Arun Gupta, Java EE & GlassFish Guy blogs.sun.com/arungupta, @arungupta
  2. 2. The following/preceding is intended to outline our general product direction. It is intended for information purposes only, and may not be incorporated into any contract. It is not a commitment to deliver any material, code, or functionality, and should not be relied upon in making purchasing decisions. The development, release, and timing of any features or functionality described for Oracle’s products remains at the sole discretion of Oracle. 2
  3. 3. Life is no straight and easy corridor along which we travel free and unhampered, but a maze of passages, though which we must seek our way, lost and confused, now and again checked in a blind alley. But always, if we have faith, a door will open for us, not perhaps one that we ourselves would ever have thought of, but one that will ultimately prove good for us. A. J. Cronin 3
