On Linux RootCause has been tested with Sun JVMs 1.4.0 through 5.0 and IBM's 1.4 JVM. Linux RootCause does not work with gcj. We have provided support for older versions of Java for specific customers: please contact us if you have a specific need. Some of our probes, most notably java_memstat make use of the JVMPI debugging interface, which has turned out to be unreliable in earlier versions, and which has been eliminated entirely in Java 1.6.

They are functionally equivalent, with minor differences in the handling of default classpath and options supported. jre.exe is the runtime stub that comes with the Java Runtime Environment (it's also in the JDK). It ignores the CLASSPATH environment setting in favor of its own internally generated default and whatever is supplied on the cmd line using -cp or -classpath. It's intended to be a bit simpler for those who are only ever running Java programs, not developing them. java.

Any subversion of the following JRE/JDKs are supported 1.3/1.4/1.5/6.0. We do recommend when possible to install the latest java releases for optimal performance and best user experience. Back to top

JARGON is a pure Java API for developing SRB (or other) datagrid interfaces. The API currently handles file I/O for local and SRB file systems and is easily extensible to other file systems. File handling with JARGON closely matches file handling in Sun's java.io API, a familiar API to most java programmers.

MMC can be compiled with jdk 1.3 or higher. It will run with jdk/jre 1.2.2 or higher. You might be able to run parts of it with an earlier jre, but table read will not work (delete the tables before running). Also some of the earlier Javas cannot parse the input lines, so only Test front end will work (unless you write your own that doesn't expect any input). It is also possible to produce a static executable if your gcc version is 3.x (run "ammc -gcj").

Make sure that you have Java Runtime Environment installed on the system. If you don't have it installed, the Java download instructions can be found on our Support page.

Note: this FAQ entry is out of date. I do not believe that any of these options work today. Dgregor 19:38, 15 February 2006 (CST) OK this is kind of minor... but this patch to the opennms start script (as it exists pre-build) adds the following env variables to configure garbage collecting... USE_CONCGC Use Concurrent Mark Sweep GC USE_PARALLELGC Use Parallel GC (multi-processor only, untested by me) LOG_GC Log GC to @root.install.logs@/gc.

In summary 1.1/AWT printing can be used for many basic cases but has largely been superseded by 2D printing (as of J2SE 1.2), and when the javax.print package was added in J2SE 1.4 it was made largely complementary to 2D printing and integrated with it for ease of us. So most applications which are focused on rendering to a printer will find it more natural to centre around PrinterJob. So the presently recommended way to print for most applications is to use java.awt.print.

You actually do not need to configure JRE. You have to set path on your system. Here is how you can do it : The process of setting up the "PATH" environment variable depends upon your operating system. You must check the documentation of your operating system, before setting up the "PATH" environment variable. However, for those, who are unable to get any such information, the procedure is outlined below: Typically it will be c:\jdk1.2\bin or c:\progra~1\javasoft\JRE\1.

Sun publishes the latest reference version of the Java 2 Platform, Standard Edition (J2SE). You can check if you need to install or upgrade your JRE from Sun's Java website.

Use the latest, greatest, fastest JVM you can get your hands on for your platform. The compiler's performance is dependent on the performance of the JVM it is running on, so the faster a JVM you can find to run it on, the shorter your compile times will be. At a minimum you need to use a Java 2 or later JVM to run the compiler (J2SE 1.3 for AspectJ 1.1). We realize that this constraint can be a problem for users who don't currently have a Java 2 JVM available.

You might want to remove the Microsoft JVM, which Microsoft no longer supports, in favor of the more recent Sun Microsystems JVM. To remove the Microsoft JVM, perform the following steps: The HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\AdvancedOptions\JAVA_VM registry subkey (to remove the Microsoft Internet Explorer (IE) options When Internet Explorer 7 is installed on Windows XP, ctfmon.exe runs in the background without purpose, and when the Run entry for ctfmon.

Actually, the JVM will exit if unchecked-exceptions (for example RuntimeException etc) are not caught.

Are there any special instructions I need to follow to install / deploy Oracle 10r R2 on the Sun Fire CoolThreads server? Open Source Software

Java-Script was developed by Netscape in the early days of the browser wars. Microsoft responded by developing JScript. The language was standardized as ECMA-262 in 1998. Today, JScript is more commonly used in Active Server Pages as an alternative to VBScript. Web hosting is your space on a web server in which all your files for your website are stored.

You can get our releases either with a World Wide Web (WWW) browser or by anonymous ftp. For details, including installation instructions, visit: The JavaTM Development Kit (http://java.sun.com/products/jdk/) Choose the version of the JDK you want, and go from there.

the time of producing the CD, Sun Microsystems were yet to release a version of the Java Access Bridge that was compatible with JRE 1.5 versions. This meant that if you installed a version of JRE 1.5 with the Java Access Bridge, then you might have problems using Jaws screen reader software. With this configuration, Jaws may not function correctly with our Java based applications, such as the digital certificate download and installation applet.

Online security is enhanced by using the latest available version of JRE. Sun Microsystems regularly upgrades its JRE software to improve online security and functionality. If you have JRE versions 1.5.0_0 to 1.5.0_03, we recommend you upgrade to version 1.5.0_06 which is available on the CD. The JRE upgrade will not affect your use of Tax Office online services but will enhance your security on other web sites containing malicious content. If you have JRE version 1.4.
