[bronby]

I have here a file , i think a library to be used by a java demo program of
a supplier providing serial interface api that will run on Linux. e.g.
libeftapi.so.1.1.3 . Where shall I place this on Linux system??? what
subdirectory? Or shall i place it in my JDK1.4\lib director(ies)? i have
tried copying this file to different subdirectories in linux and in
jdk/*/* .. but still arrive at the same RUN-TIME error...

Ask your supplier. Form the error message it looks as if it should be
somewhere in the LD_LIBRARY_PATH. However, your supplier should provide
you with a suitable installation instruction or installation program.

Its a shared library file, try as any user:

locate .so. | grep more

(Sometimes distros require you to run 'updatedb' as root as it is not
pre-configured to update automatically).

That will show you where your flavor of linux puts their libraries.
Mine shows /lib .

The correct way to do it, however, is as the other poster suggested:
try to find out from your supplier if possible or use LD_LIBRARY_PATH.

Put it in one of the paths mentioned in /etc/ld.so.conf, or in a path
mentioned in your LD_LIBRARY_PATH.

Or put it somewhere else, but update /etc/ld.so.conf (then run
ldconfig) or LD_LIBRARAY_PATH accordingly.
