JRE should usually already be installed in any of Sun's versions of OpenSolaris. What do you get as output for the "java -version" command at the command line? It should look something like this:
root at solarisunix:~# java -version java version "1.6.0_13" Java(TM) SE Runtime Environment (build 1.6.0_13-b03) Java HotSpot(TM) Server VM (build 11.3-b02, mixed mode) root at solarisunix:~# If you need the "javac" command you'll have to install the JDK (see page 870 of the OpenSolaris Bible: http://www.amazon.com/OpenSolaris-Bible-Wiley-Nicholas-Solter/dp/0470385480 ). I think you can install the 64 bit version of JDK with this command: pfexec pkg install SUNWj6dvx and you can probably install the 32 bit version of the JDK with this command: pfexec pkg install SUNWj6dev -- This message posted from opensolaris.org
