This section provides a tutorial example on how to download and install JRockit 8.0 on Windows systems.
One of the JRockit developers saw my notes on JRockit 7.0 on the Web, and suggested me to try JRockit 8.0. So I downloaded the evaluation version of JRockit 8.0, and did a couple of quick tests.
To try JRockit 8.0, I went to http://commerce.bea.com/showallversions.jsp?family=WLJR. Then using my registered name and password, I got the download page.

The installation process was straight forward by double clicking on the downloaded file. At the end, JRockit was installed at \local\bea\JRockit80_141_32.
To check the installation, I did the following in a command window:
herong> \local\bea\JRockit80_141_32\bin\java -version java version "1.4.1_01" Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01) BEA WebLogic JRockit(R) Virtual Machine (build 8.0-1.4.1_01-win32-CROSIS -20030124-1058, Native Threads, Generational Concurrent Garbage Collecto r)
There seems to be a Java compiler interface integrated in JRockit 8.0:
herong> \local\bea\JRockit80_141_32\bin\javac AnyClass.java error: cannot read: AnyClass.java 1 error
Another difference in 8.0 is that the Management Console server option is changed:
herong> \local\bea\jrockit80_141_32\bin\java -version -Xmanagement [JRockit] Management Server started on port 7090. ...
