A basic solution is a re-build of the Java source code of 'Variax Workbench' that uses the Java development environment for Snow Leopard by the developer of Line6.

Another one is a check the driver of USB-interface for Snow Leopard compatibility.

This should seek advice to Apple.

I would like the staff of line6 to report on these progress regularly.

What should Line6 does when not succeeding even if a certain period passes？

I think that making to open source about this codes of 'Variax Workbench' and USB-interface driver will show fair and the honesty to the user.

Maybe I found the solution ! !

The reason that Variax Workbench does not launch is for the lack of J2SE 5.0 in Snow Leopard.

We should add J2SE 5.0 on Snow Leopard as follows.

1) You should download the Java for Mac OS X 10.5 Update 5 from

URL: http://support.apple.com/downloads/Java_for_Mac_OS_X_10_5_Update_5.

2) You should copy JavaForMacOSX10.5Update5.pkg from mounted dmg into your (user's) home directory by Finder.

3) You should execute the following CUI commands in Terminal.app.

$ mkdir j2se5
$ cd j2se5
$ xar -xf ../JavaForMacOSX10.5Update5.pkg
$ mv JavaForMacOSX10.5Update5.pkg/Payload Payload.pax.gz
$ gunzip Payload.pax.gz
$ pax -rvf Payload.pax

4) Next, you should execute the following CUI commands in Terminal.app.

$ cd ./System/Library/Frameworks/JavaVM.framework/Versions/
$ sudo mv 1.5.0 /System/Library/Frameworks/JavaVM.framework/Versions/J2SE5
$ cd /System/Library/Frameworks/JavaVM.framework/Versions/
$ sudo chown -R root:wheel J2SE5
$ sudo rm 1.5.0
$ sudo ln -s J2SE5 1.5.0
$ sudo rm 1.5
$ sudo ln -s J2SE5 1.5
$ sudo rm CurrentJDK
$ sudo ln -s J2SE5 CurrentJDK

5) Launch Java Preferences.app in your Utility folder.

6) Finally, Check J2SE 32-bit and 64-bit added,

and you should set the priority of J2SE 5.0 32-bit to top in the Java application list (in General panel) of Java Preferences.app.

I succeeded in launching Variax Workbench on Mac OS X 10.6.2 Snow Leopard.

Of course, it works perfect.

And, you may sure to be able also to do it. Try it on your own risk.

Hi, iainpwboyd. Thanks for replying.

>Ooo-err popy.

What error occurred ?

>iainpwboyd

Thank you for the reply.

OK, I consented to what you wanted to say.

I also hope for the offer of an easy method for the beginner in the additional installation method of the Java of an old version.

My best regards.

It might be significant for everybody who loves Line6

that you reported your success here.

Good luck

Yes, popy's fix. It worked flawlessly. It probably helps that I have an understanding of Java frameworks and development in general, as well as UNIX filesystems, symlinks and so forth, but his steps are spot-on and harmless. They won't remove anything from your machine, just install an older version of the JDK and repoint symbolic links (think, folder shortcuts in Windows). It's gold.

Hi,

These command lines assume the situation that you put .dmg file in your home folder in the "User" folder in your HD top level.

You will be able to set old JDK to top priority by Java Preferences.app in any users accounts as I wrote above.

Then you will be able to use the Workbench.

Yes, you can "Copy and Paste" the CUI script line by line, and hit 'Return' key to execute at each line.

You must input your admin's login password at first 'sudo' command line.

You don't have to mind a break between step 3 and step 4 of CUI commands.

(Step 3 is for unarchiving and copying the older version of the JDK, and step 4 is for repointing the symbolic links.)

After you've done all these steps, you can trash JavaForMacOSX10.5Update5.pkg and generated j2se5 folder in your home folder.

Best Regards.

Hey. I'm a computer programmer now!

That's fantastic guys. I have now managed to launch Workbench for the very first time. Many, many thanks for your solution and support.

And for those who, like me, have never been here before: when the CLI asks for a password, you type it, but you don't see anything, not even asterisks. Go ahead and type anyway and hit return. Have faith. It works.
