What's the difference between Java 2 SDK and Java 2 RTE?

[Carl Mason]

Right now, my system is running HP-UX 11.x(32 bit). I'm trying to decide if I should install Java 2 1.4.2 SDK(bundled RTE and Java Webstart) or just Java 2 1.4.2 RTE(redistributable version).

SDK = Software Developers Kit

RTE = Run Time Environment

If you are developing Java Apps then I would install the SDK.

If you are not developing in Java, and just need to run Java apps, then I would install the RTE.

Hi Carl,

Well, SDK is the full-blown developers kit whereas RTE is the run-time version & does not support development per-se. SDK is a superset of RTE if you will.
As a rule you want/need SDK on development systems but *not* on production systems. You don't want developers "tinkering" with code on production systems after it's been promoted up there.
But having said that we've had occasion where the code being promoted required certain libraries that were only included with the SDK version. So we'd load that version in production & remove the development tools such that developers couldn't mess with the code on the prod servers.

My 2 cents,
Jeff

I think you also have to considerate which type of the system will be, the production or the test env. , if it's production, then
you probably install RTE only, if test env, then install SDK and RTE, production should never have the compiler

Ooooooh ok, I understand, now.

Thanks Mr. Wallek and Mr. Schussele
