Java don't load a library

[Andrea]

I have to launch a java class wich load a library (Lpktgen). the library is
in the same directory of the .java file. why have I this error?:

[root@localhost codice]# java Ipktgen
Exception in thread "main" java.lang.UnsatisfiedLinkError: no Lpktgen in
java.li brary.path
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1517)
at java.lang.Runtime.loadLibrary0(Runtime.java:788)
at java.lang.System.loadLibrary(System.java:834)
at Ipktgen.main(Ipktgen.java:6)

Set LD_LIBRARY_PATH so that it includes the directory containing the
library, or use -Djava.library.path.

I'm sorry but I'm a Linux newbie which is the command to set the
LD_LIBRARY_PATH?

You can also set the java.library.path system property instead:

java -Djava.library.path=/path/to/dir YourApp

java.lang.UnsatisfiedLinkError

One of my least favourite error messages, second only to
NoClassDefFoundError.

See

for hints on solving the problem.

Be careful with that approach. If anything ELSE is using the
java.library.path that code will stop working.

If you do it that way, I would use Wassup to find out the current
value of java.library.path and set it to a new value that includes the
current path.
