Hi,
Look at the /usr/java link and change it to the new version:
/usr/java/jdk/latest should already be pointing to the latest version if your install went fine.
That's what we always do when moving to a different java. Also, the back-out is really faster.
Hope it helps
Don't do this. It is the wrong way to access the current version of java. There are known performance problem in JDS and some other standard applications when you do this. The system-wide default should be left the way it is and as neo said the PATH should be updated as required, or the full path used.

JAVA-WRAPPERS(7) Java wrappers JAVA-WRAPPERS(7)NAME
java-wrappers - capacities shared by java wrapper scripts
DESCRIPTION
Most Java programs are not run directly, but through small shell scripts that take care of various things, such as finding a suitable java
environment and looking for libraries.
To ease the task of the maintainers, they rely on a library providing runtime detection, library detection and other features. This manual
page describes the common features of all those scripts, and to which point you can configure them. This is mainly done via environment
variables.
ENVIRONMENT VARIABLES
java-wrappers understands some environment variables:
JAVA_CMD
The java command that will be run. If this variable is set, it disables all lookup for a java runtime.
JAVA_BINDIR
Specifies a directory that will be looked for a java or a jdb executable (depending on the setting of JAVA_DEBUGGER). It has prece-
dence over JAVA_HOME but not over JAVA_CMD.
JAVA_HOME
A path to a java runtime. If this variable is set, all lookup for a java runtime is disabled, except that if no java executable is
found in the path, the command java is used.
JAVA_FLAVOR
A probably more easy-to-use version of the JAVA_HOME variable: instead of specifying the full path of the java runtime, you name it.
List of available flavors can be found in the file /usr/lib/java-wrappers/jvm-list.sh. See examples below.
JAVA_DEBUGGER
If this is set, the wrapper will try to pick up a java debugger rather than a java interpreter. This will fail if the jbd of the
runtime found is a stub.
JAVA_CLASSPATH
Additional classpath, will have priority over the one found by the wrapper.
JAVA_ARGS
Additional arguments to the java command. They will come before all other arguments.
FORCE_CLASSPATH
If this variable is set, it will be the only classpath. You'd better know what you are doing.
DEBUG_WRAPPER
This is probably the most important variable; if it set, the wrapper will print out useful information as it goes by its business,
such as which runtime it did find, and which command is run eventually.
JAVA_JARPATH
The path where the wrappers will go looking for jar archives. If not set, the wrapper will look into the default directory,
/usr/share/java. Warning : the wrapper will not look anywhere else than in JAVA_JARPATH. Setting it incorrectly will most probably
result in early crashes.
EXAMPLES
The examples all rely on rasterizer(1), from the package libbatik-java, but they really apply to all scripts that use java-wrappers.
Print out debugging information:
DEBUG_WRAPPER=1 rasterizer
Limit rasterizer's memory to 80 MB:
JAVA_ARGS=-Xmx80m rasterizer
Force rasterizer to run with kaffe(1):
JAVA_HOME=/usr/lib/kaffe rasterizer
The same, but using JAVA_BINDIR:
JAVA_BINDIR=/usr/lib/kaffe/bin rasterizer
Force rasterizer to run with openjdk:
JAVA_FLAVOR=openjdk rasterizer
Debug rasterizer with Sun's debugger, while printing debugging information from the wrapper:
DEBUG_WRAPPER=1 JAVA_CMD=/usr/lib/jvm/java-6-sun/bin/jdb rasterizer
BUGS
Care has been taken to make the wrappers bug-free. If that was not the case, please file a bug report against the java-wrappers package.
If you wish to submit any problem with a java executable relying on java-wrappers, please also submit the output of the command run with
DEBUG_WRAPPER=1. It will save one mail exchange and therefore potentially reduce the time it takes to fix the bug.
DEVELOPERS
There is currently no documentation about writing a wrapper script save the comments in /usr/lib/java-wrappers/java-wrappers.sh. If you
have to write one, we suggest you base yourself upon, for instance, the rasterizer wrapper script, or any other one (just pick up any
direct reverse dependency of java-wrappers and look for scripts).
