Java and Fedora

[Ryan Nix]

Why is Java always so difficult to setup?  Specifically speaking, I'm 
trying to install Limewire for a customer to appease her for trying a 
Linux desktop.
Is there something that has to be configured in each user account to run 
Limewire?

Are there any plans to bundle a JVM like Sun's or IBMs in the future?

Do you have java installed yet? there is a Fedora faq on installling java
and it is very easy to install. i installed limewire and it said path not
found before i was able to install it i had to create a java.sh file that
was available to everyone.

I've created a file called java.sh in /etc/profile.d, which contains this :
if [ -z "$JAVA_HOME" ]; then
  export JAVA_HOME=/usr/lib/jre-1.4.1_01
  export PATH="$PATH:$JAVA_HOME/bin"
fi

This way I have the java executable in my path, and everything works fine.
You may have to change the JAVA_HOME path, depending on your version.
The only thing left is to add the symlink to the java web plugin into
mozilla's plugin directory, but it has nothing to do with limewire :-)

Hope this helps

I just altered /etc/bashrc to include the lines

JAVA=/usr/local/j2sdk1.4.2_03
PATH=$JAVA/bin:$PATH
MANPATH=$JAVA/man:$MANPATH
LD_LIBRARY_PATH=$JAVA/lib:$LD_LIBRARY_PATH
export JAVA

(I export the others after adding more to them)

I have seen some programs looking for an environement variable called
JAVA_HOME to find the java distribution. I don't remember the names though
(maybe it was eclipse). I think it's better to use the name JAVA_HOME then.

Don't forget something equivelent in java.csh for the (t)csh users you
maight have.

Using /etc/profile.d is better than adding it directly to /etc/profile.
It's much easier to remove/modify if need be later. Hopefully the JVM
distributions will start adding those files like this other in there now.

I don't believe Sun or IBM plan on open sourcing their JVM.

It's always been pretty straightforward for me -

Install the sun jvm, then make sure the java command is in the path for 
all users, e.g. by suitably editing /etc/profile

For web stuff, just make the symlink in /usr/lib/mozilla/plugins from 
the <pathname>/j2sdk1.4.2/jre/plugin/i386/ns610-gcc32/libjavaplugin_oji.so

Joe has right. It should work.

Because the vendor assumes that you are a UNIX admin, and want to do
everything yourself... It is like distributing Windows programs and
expecting the user to go and edit the registry by hand to make the program
start. --it is insane. 

Making a symlink in the /bin folder pointing to the Java executable worked
for me... This seems a lot simpler and global than fiddling with paths and
variables...

jpackage.org and yum install limewire ;)

For a personal machine you are the admin, just as you are in Windoze.

Imagine having a program that only works if you install it in a certian
directory and that must replace system librarys (DLLs) with particular
version( but that version might break some other app you use). That's
insane.

Oh wait, that describes most Windoze software. (Try installing to a
drive other than C: because it's full. Oops, you still need 150MB on
drive C:. Ok remove some old app you no longer use. Now It doen't work
quite right. Been there done that. Won't do it again.)

And a lot harder to revert later if you need to. Using systematic
methods like /etc/profile.d are muche easier to deal with.
1) the package lists the file in /etc/profile.d as belonginging to it
2) the file can contain comments to make it obvious what package it
belongs to and what the settings there do
3) that tells users how to customize those setting if they want/need to.

Try that with M$ Windoze and the registry.

Here's one: HKEY_LOCAL_MACHINE\Software\Microsoft\Java VM\Security

ValueName=EditCustomPermissions
ValueData=00 00 00 00

What is that for? What do different values mean there?

How do I set a custom CLASS_PATH that is always used when I run java dut
doesn't affect others that use the machine? I don't think
HKEY_LOCAL_MACHINE_Software\Microsoft\Java VM\Classpath would do it.
but there is no indication that I coud set
HKEY_CURRENT_USER\Software\Microsoft\Java VM\Classpath to do it. Would
it be saved across logins? Would it append or replace the value from
HKEY_LOCAL_MACHINE?

At least I know that changing the variable in linux will 1) work,
replace the old value, and not last across logins unless I set it with
my user startup scripts.

The vendor assumes you are an admin ie the ONE person between N who is
doing system administration  and that means that he can spend
a lot of time studying because at organization level it is only a small
overhead.

For a personal computer it  is one person between one and that means
that any time spent on study and work on system administration detracts
directly from real work.  That means that the user will have little time
for it and cannot develop expertise.  If he tries then he will not doing
real work.
