Java patching

hello,
I'm a Solaris admin and I was asked to patch some RHEL servers. I'm having trouble trying to figure out the RHEL java version. Can someone help me?

This what I do in Solaris
Code:
java -version
java version "1.5.0_34"
java(TM) 2 Runtime Envirement, Standard Edition (build 1.5.0_34-b03)
Java HotSpot(TM) Server VM (build 1.5.0_34-b03, mixed mode)

This what I see on RHEL
Code:
java -version
java version "1.4.2"
gij (GNU libgcj) version 4.1.2 20080704 (Red Hat 4.1.2-52)

or
Code:
java -version
java version "1.6.0_22"
OpenJDK Runtime Envirement (IcedTea6 1.10.6) (rhel-1.25.1.10.6.e15_8-x86_64)
OpenJDK 64-Bit Server VM (build 20.0-b11 mixed mode)

I went to the RHEL site and looked at this page.
https://access.redhat.com/security/cve/CVE-2010-4454
The issue is the version numbers don't match the layout I get from the command line. I can't figure out if my version has been patched to cover the vulnerability. In Solaris The latest update is 1.5.0_34 & 1.6.0_31 (put out in Feb), I would like to have the RHEL servers patched to the same level.

OS
RHEL 5.x, (5)
RHEL 4.x (1)

Can someone help me understand the versioning RHEL is using.

NAME
rmiregistry - Java remote object registry SYNOPSIS
rmiregistry [ port ] DESCRIPTION
The rmiregistry command creates and starts a remote object registry on the specified port on the current host. If port number is omitted, the registry is started on port 1099. The rmiregistry command produces no output and is typically run in the background. For example: example% rmiregistry & A remote object registry is a bootstrap naming service that is used by RMI servers on a host to bind remote objects to names. Clients can then look up remote objects and make remote method invocations. The registry is typically used to locate the first remote object on which an application needs to invoke methods. That object in turn pro- vides application-specific support for finding other objects. The methods of the java.rmi.registry.LocateRegistry class are used to get a registry operating on a particular host or host and port. The URL-based methods of the java.rmi.Naming class operate on a registry and can be used to look up a remote object, bind a simple (string) name to a remote object, rebind a new name to a remote object (overriding the old binding), unbind a remote object, and list the URLs bound in the registry. OPTIONS
The following option is supported: -Joption Used in conjunction with any java option, this option passes option (no spaces between -J and option) on to the java inter- preter. SEE ALSO
