macOS Terminal + Java Installation

[i.shaun]

This is actually a Linux (Fedora 8) Question. It uses Terminal, which is similar to OS X's Terminal.app So I figure someone may be able to help me out.

I am attempting to install Java runtime environment on Linux, and following the Instructions on the Java site.

I can make the .bin file executable, I can run it in Terminal, View the license agreement, and Install Java in a directory.

The problem comes when attempting to create a "Symbolic Link" to the Java plugin, from the firefox Directory.

"ln -s <path to java file.so>"
"./javaplugin.so"

After doing this, I get "Segmentation Error"

If I try again, I get Error creating symbolic link: File Exists (and it does exist there in the firefox plugin directory)


As of now, firefox will not even start. Does anyone know what could be causing this?

"ln -s <path to java file.so>"
"./javaplugin.so"

Is this what you're literally typing (or cut/pasting) in the terminal? If it is, the format for creating a soft link is:

ln -s file linked to [link]

Where the 2nd argument may be optional (if you want to give the link a different name than the file linked to)

"ln -s <path to java file.so>"
"./javaplugin.so"

Creates a link to the java library with the full path name as the link name, and then tries to execute a shared object library from the shell.

What they meant you to type was:

ln -s full path_to_java_file.so javaplugin.so

Remove the full_path_to_java_file.so from your Firefox plugin directory and retype the line exactly as shown above.

Thank you so much for the info. I thought i was gonna drown 'cause I was way over my head with this Linux stuff haha. Hopefully I can do Linux installations similar to this without a problem in the future, but if the need arises, I'll be back. Most programs I need now are self-installing ones from the Fedora "Add/Remove Software" program, and therefore won't immediately require Terminal.


and Sorry about the wait, been a while since I got back on it. I had to re-install Linux because firefox was screwed, and I couldn't un install

After re-installation, I downloaded the java jre-6u6-linux-i586-rpm.bin file (didn't work, one plugin installed but did nothing, the other crashed firefox)

so I deleted it, and got the non rpm file (not sure what the difference is) -- It works fine now.

Anyway, thanks again, this Terminal stuff is really confusing to me, and I consider myself an Advanced user. Not that advanced I guess, but I learn.
