[gentoo-user] JDK 7 on server

[gentoo-user] JDK 7 on server

[Nilesh Govindrajan]

Hello,

I'm planning to run GlassFish on my server. I'm pondering whether I
should just go away with the default icedtea-bin package or use
oracle-jdk-bin.

I'll be renting out services to customers, so compatibility is
definitely a concern. I'm not exactly sure what the differences are
between Oracle JDK & OpenJDK; the differences I found so far on Google
are old and make sense only for Java 6.

Java EE will work perfectly with icedtea-bin?

Automatic update is also an issue. Emerge will do it for me in case of
icedtea-bin but not in case of Oracle JDK .. or is there some other
option? (Non-portage solution is okay, something is better than nothing.)

   Hello,

  To my understanding, Oracle JDK binary is created from the source code
  released from the OpenJDK project with some Oracle's own propriety
  code. The other difference is Oracle's JDK binary is released under
  Oracle Technology Network Developer License Terms for JAVA EE SDK,JDK
  where as OpenJDK code is under GPL + linking exceptions.

So it would be correct to say that for Java EE applications, icedtea
would be enough? As per the link you gave me, it says some graphical
components & fonts are extra, none of which are used in case of web
applications.

Sorry for top post using my phone
Ice tea  is Java se. Glass server uses
Java EE because EE has added API and
Runtime to build enterprise secure apps.
sorry the link did not help.

   I was not satisfied with the reply i sent earlier. I'm not used to
   yet used to typing on a smartphone yet. 
   Java EE extends Java SE platform with added API for 
   object relational mapping, distributed and multi-tier architecture,
   web services,etc. Making it more useful servers. where as icedtea
   is basically Java SE,and would be missing the added components
   for Glassfish server that Java EE contains. 
   
   Found Java EE documentation from Oracle:
   http://www.oracle.com/technetwork/java/javaee/documentation/index.html
   http://docs.oracle.com/javaee/7/firstcup/doc/java-ee001.htm#GCRLZ

No problem. Actually glassfish needs JDK7 as per their docs. So any JDK7
should work. Java EE is just a specification to be implemented by
application servers.

  Yes Java EE extends Java SE platform with add ons, that is why i was
  not satisfied with the email i sent from my phone, i felt i was not 
  being clear. 
  I would suggest to use Oracle's JDK7 since it what glassfish calls
  for. that is what i'm using  in Gentoo along with
  Netbeans,etc. 

  Best Regards.

    Nilesh,
 
    I also want to add, it has been pleasure conversing about Java with
    you and thank you for your patience.
