Java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path debian

I am trying to use the rxtx serial communication library on debian and I added librxtx.so to the path of my native library, but still this exception has occurred.

For me, the solution was to copy the link to the library to where jvm can see it like this:

 cp '/usr/lib/jni/librxtxSerial.so' '/usr/lib/jvm/java-6-sun-1.6.0.26/jre/lib/i386'

Set LD_LIBRARY_PATH to the directory in which you have the .so file.

Specify the directory where you have the .so /home/abc file

Use this command:

 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:"/home/abc"

In java, download .so as follows.

 System.loadLibraryPath("rxtxSerial");

To install it permanently, you must put the same line in the .profile file that will be in your home directory.

I will copy and paste the rxtx INSTALL help

 Solution 1: move the file to a place that works $ mv /usr/local/lib/librxtxSerial.* /usr/local/java/jre/lib/i386/ Solution 2: add the location of librxtxSerial to LD_LIBRARY_PATH $ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/ Solution 3: pass the location in on the command line $ java -Djava.library.path=/usr/local/lib/ ...

You need to put the rxtxSerial.dll file in the jreXX / bin folder
