can anyone recomend a good java download for mandriva? i have buggered about with one i downloaded this morning but when i run ./sdk....etc it says permission denied even if i'm logged in as root that was both -rpm.bin and .bin neither would install
if it isn't possible with mandriva that would be fine as i am quite fed up

Go here.
Presumably select "Download JDK 5.0 Update 4".
Click accept and then choose the linux .bin
# chmod 755 jdk-1_5_0_04-linux-i586.bin
# ./jdk-1_5_0_04-linux-i586.bin

Should be as simple as that.

that's what i tried but it just keeps saying permission denied

edit i have now managed to install an older version and will try and use the update 1.5 later as it says it is busy and come back later
thanks

Just think, if you weren't such a tight-fisted so-and-so you could have joined MandrivaClub and installed the official rpms easily

that would be correct
how do you change the environmental variables to put java 1-5 onto the end of it i have looked at sun and they say that you have to do it but not how as i cannot use javac because it says

[Rhakios]

No idea, but they do have a help forum where people will probably tell "that's a java problem, try a java forum"

If by env vars, you mean the output of the command env, and if the bit you are looking for is your $PATH, you can modify your default path with the export command, indeed many of these variables can be modified on a session-only or permanent basis. Have a look at your .bash_profile and .bashrc in your home directory, I forget if Mandriva sets both of these or not.

Customising the environment might make a good article for the magazine.

if i use

[Rhakios]

If you do:
rhakios@pythia:~> env | grep -i java
JRE_HOME=/usr/lib/jvm/java/jre
JAVA_BINDIR=/usr/lib/jvm/java/bin
JAVA_HOME=/usr/lib/jvm/java
SDK_HOME=/usr/lib/jvm/java
JDK_HOME=/usr/lib/jvm/java
JAVA_ROOT=/usr/lib/jvm/java

do you get all that or not?

Exporting extra variables to the $PATH is quite easy, for example:

export PATH=$PATH:/your/new/path

will add /yor/new/path to your $PATH without overwriting the original. If you want to make other permanent changes to your environment, then put them in your ~.bashrc

i get what you have written but are those just for one session?
i would want it so that i just open konsole and could then start javaring, what i don't get is ~.bashrc?

In your home directory, there should be a hidden file .bashrc, all files with a "." in front are hidden by default. You can set variables for your environment by modifying your .bashrc, remember that your log in is essentially X executed in a bash session (unless you have a chosen a different default shell of course).

hello i have installed java successfully!!(not had access to linux through modem probs )
i hava installed it in /java and it all went ok
however when i try to save a java program to this dir it says cannot write to it check that i have enough permissions and that i have enough disk space?
i have the majority of space for /home(about 66gig) and the rest are shared,but i cannot install it in home as it must be an empty directory
any thoughts?

If /java is (as your formatting suggests) mounted directly beneath the root partition, then you will probably not have permission to write to it.
The rest of your post doesn't make sense, "it", what is "it"? Java or your program.

If you wish to write to /java then you can change the permissions to suit, either make it world writable (bad idea), or change the owner (somewhat better idea). For the latter, you might use something like:

chown -R 1sf (troll) /java (should 1sf (troll) happen to be your user name).

sorry it is bash
when i type in chown -R paul/java at command line as root the display says

[Nigel]

there should be a space between "paul" and "/java"
