Java/JMF on Linux - where to export paths for browsers?

[Robert Mark Bram]

Hi All!

I have this in my .bash_profile to get JMF to work through a browser.. as
per in

export JAVA_HOME=/usr/java/j2sdk1.4.2_02/
export JMFHOME=/usr/java/JMF-2.1.1e
export CLASSPATH=$JMFHOME/lib/jmf.jar:.:${CLASSPATH}
export LD_LIBRARY_PATH=$JMFHOME/lib:${LD_LIBRARY_PATH}
export PATH=/usr/java/j2sdk1.4.2_02/bin:$PATH:$HOME/bin

This is to get JMF to work through a browser as per instructions here:
http://java.sun.com/products/java-media/jmf/2.1.1/setup-linux.html

$ set | egrep -i 'java|jmf'
CLASSPATH=/usr/java/JMF-2.1.1e/lib/jmf.jar:.:/usr/java/JMF-2.1.1e/lib/jmf.jar:.:
JAVA_HOME=/usr/java/j2sdk1.4.2_02/
JMFHOME=/usr/java/JMF-2.1.1e
LD_LIBRARY_PATH=/usr/java/JMF-2.1.1e/lib:/lib:
PATH=/usr/java/j2sdk1.4.2_02/bin:/usr/java/j2sdk1.4.2_02/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/home/robertmarkbram/bin:/home/robertmarkbram/bin

This doesn't work - I ended up using a workaround:
$ su
Password:

/home/robertmarkbram
# cp /usr/java/JMF-2.1.1e/lib/jmf.jar /usr/java/j2sdk1.4.2_02/jre/lib/ext/

/home/robertmarkbram
#mkdir /usr/java/j2sdk1.4.2_02/jre/lib/ext/i386

/home/robertmarkbram
# cp /usr/java/JMF-2.1.1e/lib/*.so /usr/java/j2sdk1.4.2_02/jre/lib/ext/i386

But my question is why didn't my paths work? Should the paths be in
another file?

Hello. Is it possible that somewhere along the line that a shell
without a login is spawned somewhere that didn't read that
..bash_profile?

Are multiple users trying to use JMF? Is the browser running as a
differnt user or something?
Have you tried creating a /etc/profile.d/jmf.sh file and putting you
export's there?

Hi Mike!

Thank you for your reply!

Hello. Is it possible that somewhere along the line that a shell

.bash_profile?

I can confirm that when I launch Konsole it reads .bash_profile - and I
launch the browser from the Konsole too.

Are multiple users trying to use JMF?

Just me atm..

Is the browser running as a
differnt user or something?

When I check with ps, I see that the UID is mine..

Have you tried creating a /etc/profile.d/jmf.sh file and putting you
export's there?

I can try this -- how will the browser use this though?

How about trying java -Djava.library.path=$LD_LIBRARY_PATH ?

Or how about trying to make it open another terminal that echo's the
execution?

Or how about wrapping the java command in an strace or ltrace?
strace java ...

I did a JNI project a few times and I can't remember what I did, I
think I ended up loading the library using System.load(new
File(System.mapLibraryName("mystuff")).getCanonicalPath()), to bypass
any OS related fidgiting of paths.
I wonder if you could hack something in your code to load the lib in
the hopes that once the JMF portion runs that the library is
considered already loaded.

Hi Mike!

How can I make a browser do this? This sounds like the perfect debugging idea.
