The Windows XP work station I use in my lab does not have J2SE

C:\Documents and Settings\antonyliu>java -version
java version "1.4.2_08"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_08-b03)
Java HotSpot(TM) Client VM (build 1.4.2_08-b03, mixed mode)

C:\Documents and Settings\antonyliu>

I don't wanna go through the hassle to ask the administrator of my
windows work station to install the newest J2SE package. So, I
installed JDK1.5 under my home directory C:\Documents and
Settings\antonyliu\jdk1.5

I've set the PATH, CLASSPATH and JAVA_HOME to point to this jdk1.5
folder. Look:

PATH=%PATH%;C:\Documents and Settings\antonyliu\jdk1.5\bin
CLASSPATH=%CLASSPATH%;C:\Documents and Settings\antonyliu\jdk1.5\lib
JAVA_HOME=C:\Documents and Settings\antonyliu\jdk1.5

But whenever I run java -version, it still shows me the old one. So,
is it possible to specify a JRE different from the system default?

Thanks.

The OS is finding java in the first place it can which is in the 1.4
directory. If you place the 1.5 directory in front of the existing 1.4
location in the path then it will be found first and thus be used.
PATH=C:\Documents and Settings\antonyliu\jdk1.5\bin;%PATH%
