I'm trying to run a jar that is located at /Library/Java/jack.jar, this works:

java -jar /Library/Java/jack.jar

However, I want to run it without the path, relying on the class path. The default class path includes /Library/Java, but this fails with "Unable to access jarfile":

java -jar jack.jar

Why? What's more, this also fails (same error):

java -cp /Library/Java -jar jack.jar

What's the problem/what am I doing wrong?
Thanks.

Using PHP 5.3 as an Apache module with Apache 2, on OS X 10.7.

When I open Terminal and enter echo $PATH I get:

/opt/local/bin:/opt/local/sbin:/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/imagemagick/bin

But when I run getevn('PATH') in PHP I get:

/usr/bin:/bin:/usr/sbin:/sbin

Which means most calls to exec() in PHP fail to find the commands/binaries I want. I've tried these two in httpd.conf:

SetEnv PATH /opt/local/bin:/opt/local/sbin:/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/imagemagick/bin

PassEnv PATH

Neither have any effect. How do I get PHP/Apache's PATH variable to mirror my users PATH variable? (Ideally in such a way that if mine ever changes Apache's doesn't need manually changing as well.)

We're trying to optimise our network transfer rate from the client PCs to the file server, but having no luck.

If I run an iperf test between a client PC (Windows XP) and our server (Linux) with a large TCP window size (the default is 8kb) I can get 60 Mbps. But when I run an SMB transfer speed test all I get is around 35 Mbps. When I run an FTP transfer speed test all I get is around 32 Mbps.

I thought this was to do with the TCP window size, but I have now increased that to 256960 and it made no difference at all.

Any ideas what I'm doing wrong? Or is 35 Mbps all I should expect?

Cheers,
Jack

Sure I'm just missing something obvious here, but I have this:

RewriteCond %{SCRIPT_FILENAME} !-f
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteRule ^(.*)/(.*)$ $1_$2 [N]
RewriteRule ^(.*)$ $1.php [QSA,L]

Which I would like to rewrite /shop/basket to /shop_basket.php. Instead if I go to / I get and internal server error, and if I go to /shop/basket it gets stuck in an infinite loop.

Any ideas?

I'm currently setting a number of environment variables in OS X in /etc/profile using the export command. These are all listed correctly when I check in terminal, however when a script is executed through cron none of these variables are set.

As I understand it cron runs with its own environment variables, but how can I get my custom ones into the cron environment as well?

Please explain in the simplest possible way, as you may have guessed, this isn't something I know a lot about.

Thanks, Jack
