![]() Hope this helps anyone finding the same problem. Awkward but at least I now have a workaround fix. If FF's UA is spoofed then Java raises exception next time FF starts. This means FF's UA must be default (not spoofed) at startup. Replying to myself: I tracked down a possible cause for Java raising the exception in FF2 by reading the long standing bugzilla 83376, (since 2001) It seems Sun's Java plugin (even the latest one) under FF2 with useragent (UA) spoofing (still needed for some websites) fails because, in Sun's own words from 2001: "Java Plug-in depends on user-agent string for version information, no fix will be made." Nice and final. Maybe Sun or Firefox have not managed to get JRE 6 working with FF2+ under Vista yet? - 84.223.117.102 22:51, 1 September 2007 (UTC) Reply However, with Firefox 2.0.0.6 Sun's test page reports, as others are finding. When I use Netscape Navigator (version 9.0b3) to go to Sun's test page, the test page reports Version: 6 update 2. FWIW I have just now downloaded what Sun calls the latest version on Vista Home Premium and the Java Control Panel reports version Standard Edition 6, version 1.6.0 (build 1.6.0_02-b06). My hunch is that 6 = 1.6, is that right?- 87.162.24.126 10:46, 24 July 2007 (UTC) Reply That would be my guess too, but Sun does not seem to outright acknowledge that 1.6 might be the same as 6, and which subversion of 6. My installed version is quite recent (few weeks) but has version number 1.5.0_11. The test page wants me to update to "version 6 update 2". On the sun.com download page, the current version is "Java(TM) SE Runtime Environment 6".

Michael ( talk| contrib) 19:15, 1 February 2007 (UTC) Reply of course, the way sun restrict the spec, only runtimes based on Sun's implementation can get access to the test kit, which is their proof of compliance with the licensing requirements of Java. In short: no, the JRE is not a "bundle of software from Sun Microsystems". Also, of note, are "free" Java implementations (a free as-in-speech) Java implementations that are completely independent of any Sun source, eg, Apache Harmony. ( Note1: ok, sure, there's the JCP, but in reality Sun owns the language.) ( Note2: Ok, not anyone the people writing the implementation have to promise not to break the spec (eg, like Microsoft tried to do) by licensing the spec from Sun - but that's just the right to implement a virtual machine.) See List of Java virtual machines for a short(!) list. Sun in effect owns (*note1) the Java specification, but anyone(*note2) can write a Java Runtime implementation. However, in the future, this shared runtime environment will be implemented more consistently in order to save resources.This article unfortunately not only is incorrect, but propagates the misconception that to run Java you need Sun Microsystems: > Generally these applications also run without XULRunner. ![]() XULRunner: A runtime environment for XUL applications like Firefox, Thunderbird and Songbird.WINE: This runtime environment can be used to run Windows apps on other operating systems, such as Linux, FreeBSD, and macOS.Visual Basic Runtime: Required for several shareware and freeware programs.However, even its creator is critical of several aspects of it and is developing Deno, a new, more modern and secure runtime environment for JavaScript on the server end.

This feature is available only to installers running on Microsoft Windows. ActionScript Application (ASAP): Offers building blocks for Flash developers. This document applies to JRE installers starting in Java SE 6 update 10 release.Some other well-known examples of runtime environments include: Since the Java Runtime Environment is a software platform, it’s called the “ Java platform” and consists of a programming interface, a virtual machine, and various libraries. This makes Java programs largely independent of operating systems and thus able to be executed in any operating system with the right runtime environment. One of the best examples of a runtime environment is Java: The Java Runtime Environment is a prerequisite for running Java programs.
