Install wont find JRE- $JAVA_HOME

Hi, i have been googling and trying things for a few hours now but cannot get the installation of NeXpose to work

The error is:

Code:

    This application requires a Java Run Time Environment (JRE)

          to run. Searching for one on your computer was not successful.

          Please use the command line switch -is:javahome to specify

          a valid JRE.  For more help use the option -is:help

These results are from my Backtrack install, but i have tried on my main Mint 10 install, they are pretty similar

$ which java
/usr/bin/java

$ java -version
java version "1.6.0_10"
Java(TM) SE Runtime Environment (build 1.6.0_10-b33)
Java HotSpot(TM) Server VM (build 11.0-b15, mixed mode)

$ echo $PATH
/opt/kde3/bin:/opt/kde3/games:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/opt/oracle/instantclient_10_2:/opt/oracle/instantclient_10_2

$ echo $JAVA_HOME
(empty)

I did
$ locate jre

and found the location of the jre install? from what ive googled this seems correct:
/usr/lib/jvm/java-6-sun-1.6.0.10/jre/ (of which contains /bin/java)

So i then added this to the JAVA_HOME variable

export JAVA_HOME="/usr/lib/jvm/java-6-sun-1.6.0.10/jre/"

also added this to PATH

export PATH=$PATH:/usr/lib/jvm/java-6-sun-1.6.0.10/jre/

What am i missing here? :(

any more info just ask

Does the command line switch is:javahome accept a path to your Java or JRE directory?

it doesnt seem so mate, does the path i posted seem correct? ive tried variations of that, + /usr/bin one

if i scroll up on the installation-type screen in terminal, i noticed this also:

Code:

Initializing InstallShield Wizard........

          Extracting Bundled JRE.

im wondering whether its something to do with how im running the .bin ?

$ sudo bash ./filename.bin

plain

$./filename.bin

does not work, and ive seen an installation of NeXpose tutorial in which it does

grrrr

Usually to install a program, you need to be root, therefore the need for 'sudo'. You can try setting the JAVA_HOME environment variable or add it to the PATH as root.

Code:

sudo su

export JAVA_HOME="/usr/lib/jvm/java-6-sun-1.6.0.10"

Then run chmod u+x on the .bin to make it executable.

If you read my post fully you'll see i already did this?

Sorry, but did you set the environment variable while logged in as root? That bit was unclear to me...

In any case, perhaps the -is:javahome switch does accept a path? Have you tried adding -is:javahome /usr/lib/jvm/java-6-sun-1.6.0.10 when you run the install script?

(By the way, in my experience, usually $JAVA_HOME is set to the top level directory of your Java installation, so even if the JRE is installed in ../../java/jre, you still set the variable to ../../java)

EDIT: I just looked at the install script, you can also add the option -is:log /path/to/log in order to save more information on what's happening with your install...
