It looks like your java version is not 1.5 (required for TR).

You can check using a terminal (java -version) or if you are on windows look it the Add / Remove programs in the control panel.

Thanks for the reply....

Ok......That version of Java is not coming up in my terminal, but I just installed the Apple update 5.0....and clicked it in my Java perfs....

What is the trick to activate 1.5?[/img]

Are you running Mac OSX 10.4? If so, then you should have the latest Java VM.

As noted above, to check your version, do this:

Run the Terminal utility (it's in your Applications folder, in the Utility sub-folder).

When it opens, type the following:

java -version

and press Return. Note that there is a SPACE between the word "java" and the "-version" part... if you don't include the space, this won't work.

That will tell you the version you have.

This is what the consol said:

Welcome to Darwin!
your-privacys-power-mac-g4-agp-graphics:~ readthis$ java -version
java version "1.4.2_09"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_09-232)
Java HotSpot(TM) Client VM (build 1.4.2-54, mixed mode)
your-privacys-power-mac-g4-agp-graphics:~ readthis$

Which indicates I am using the wrong version...I D/led the 5.0 Java updater from Apple, installed it, and went to the perfs file to select the 5.0 etc.....it didn't change the version? What do I do to get the 1.5 to load?

There is probably an official way of changing the current java version used which is probably in the instructions for installing.

However I did it this way ...

Use the Terminal.app (in Applications/Utilities)

...$ cd /System/Library/Frameworks/JavaVM.framework/Versions
...$ ls -l

you should see a list of java version directories and a link to the current one similar to this ...



So what you need to do is change the CurrentJDK link to 1.4.2 to link to 1.5.0
However you probably need higher authority first so

...$ sudo sh
Password: enter your root / administration password

then
...# rm CurrentJDK
...# ln -s 1.5.0 CurrentJDK

all done
...# java -version

should show 1.5.0 something

If anyone knows an easier way please post.

Got it running!!!!!!

I just can't describe the feeling of seeing that Icon just simply launch!

Now to tackle the SW and the GTD program. I'm going to get the thing working cross platform next...on my XP machine.....then onto Linux and then an TRS-80......

SOOOOOOOOO.....THE NEXT BIG QUESTION IS........

WHY DID MY LITTLE SNITCH LIGHT UP WITH A CALL TO YOUR SERVERS WHEN I BOOTED????? WHAT ARE YOU GETTING FROM ME THAT I DON'T KNOW ABOUT??????

TR checks for the current version number on startup (which is in the version.php file on our web site). You can disable this in the preferences if you want to.

Thanks Jeremy for the step by step Terminal session. I ended up copy and pasting line by line and hey presto - success.

Hi Jeremy
I have also downloaded the latest Java but having no luck on a Mac.
I have tried entering the codes that you suggest for getting it to use the 1.5 version but not getting anywhere.
I reads
...$ command not found

Hope you can enlighten me.
thanks

I guess that you have installed the Java version 1.5

If you use the Terminal.app and follow the instructions I gave it should work.
Hint: don't type the ...$ or ...# (these are just showing that there is a command line prompt that should end in a $ or #)

If you still have problems please be specific about which command is not found and what you did exactly.

Sorry but can you explain the root user bit. Do I have to set up a root user? I am not familiar with doing the coding.
thanks

So you can use: sudo -s (or sudo sh) to gain superuser privileges using your normal user password. This is the case except when the root account has been enabled - if it has then you need the actual root account password.

HI Jeremy

Good news. System update came up with the latest Java 5 update and once I did this Thinking Rock has opened and stayed open! So I have not had to do your work around.

thank you for your prompt replies.
Will now experiment with the programme.
