Here is Java for 10.4, Release 9. This appears to be the newest version of Java for 10.4. You will have to update to 10.4.11 to install this (which you should do anyway).

Did you quit all your browsers before installing?

It appears that Elluminate Live depends on Java Web Start. If you open Terminal (/Applications/Utilities/Terminal.app) and enter the command "javaws" (without the quotation marks), what appears in the Terminal window? If you get "-bash: javaws: command not found", you don't have the Java Web Start launcher available (or at least in your path). Let's start here though.

NOTE: Moved to more appropriate forum.

Liquid and computers don't mix. It might seem simple, but we see an incredible amount of people post here about spills. Keep drinks and other liquids away from your expensive electronics!

Ok, when you moved stuff from your Applications folder, you wouldn't have deleted Java because Java resides in a folder outside of /Applications. For instance, the java compiler (javac) resides in /usr/bin along with java (the runtime executable/interpreter) and javaws (Java Web Start launcher). Execute "whereis javaws" (w/o quotation marks) in the Terminal - it's possible it's no longer in /usr/bin for some reason.

What does "whereis java" return when you execute it?

If the command in my previous post returned nothing (ie. you executed it and nothing came back), then javaws doesn't exist in "the standard binary directories" (see man page here). The directories searched by the whereis utility on my machine are /usr/bin, /bin, /usr/sbin and /sbin as told by the "sysctl user.cs_path" command. I would imagine it is the same for you. While this may be more info than you needed, it's for anyone who might be interested.

Here is one more technique that can be used to find something. Execute the following in a Terminal:
Code:
sudo /usr/libexec/locate.updatedb
This will ask for your password. Give it some time to execute. After executing that, execute the following:
Code:
locate javaws
Paste back here what that prints to the Terminal window.

If that returns nothing, this command probably won't either but it can't hurt to try. Executing the following command will search your root directory (equivalent of C: on Windows) for javaws:
Code:
sudo find / -name javaws
This will take a while and may ask you for you password.

I find it hard to believe that you deleted this file - you would have know if you deleted javaws as it's in a directory that is hidden by default in Finder. If you did indeed delete it, the "copy" of javaws in /usr/bin is actually just an alias. So, if it isn't there, we can recreate it. For now, just try the aforementioned searches.

Open up the application called Terminal in /Applications/Utilities. Copy and paste the aforementioned commands into the Terminal window one at a time and press enter after each.

What's OniOutliner?

If both the locate and find commands returned nothing, then javaws doesn't exist. You did somehow delete it but I don't know how. Let's try something else because I find it very hard to believe you somehow deleted everything that has to do with Java. What are the contents of the /System/Library/Frameworks/JavaVM.framework/Versions folder? To get there, open up "Macintosh HD" on your desktop and go from there.

One thing I also notice is that earlier you say that you downloaded the Java update I linked to earlier but did not install it. Did you install it? Did you update to 10.4.11?

Yes you do. You must have this directory or your machine wouldn't be working (if it was, it wouldn't be working very well). See here for an explanation for the directories on your Mac. Note the description for /System: "System related files, libraries, preferences, critical for the proper function of Mac OS X".

Click on your desktop and push Shift-Command-G at the same time. In the ensuing box, enter "/System" (w/o the quotes) and click Go. Now, navigate to Library > Frameworks > JavaVM.framework > Versions. What is in that directory?
