liblpsolve55.so: cannot open shared object file: No such file or directory

Good Morning,
I am working with lpsolve with eclispe and in Java.
I can import correctly the program but when running it I got the exception :
Exception in thread "main" java.lang.UnsatisfiedLinkError: /usr/lib/lp_solve/liblpsolve55j.so: liblpsolve55.so: cannot open shared object file: No such file or directory

at scheduler.Main.main(Main.java:353)
Or, I have edited the native library path which is : usr/lib/lp_solve.
Can anyone help me ?
Thank you !

Apparently Eclipse is finding liblpsolve55j.so in /usr/lib/lp_solve but is not looking in the same place for liblpsolve55.so.
The only workaround I found is to manually load the library with System.load("/usr/lib/lp_solve/liblpsolve55.so").

I had the same error.
Look at the compiled source. In the target folder you need all the scripts of the mutlilang available to execute all of them.
Look at target/classes/resources/ if there are any files. If not and if even you do not have the folder in target/classes copy the the resource folder from multilang/resources into the target path.

How to see Aparapi generated OpenCL code

I am having Aparapi translating Java code to OpenCL. However I wonder how I can see the generated OpenCL code. The website says "by using adding -Dcom.amd.aparapi.enableShowGeneratedOpenCL=true to your command line when you start your JVM". Being new to this technology, I am not sure how exactly you can do this? Can anyone please help by elaborating the process?
Added part:
Thank you. But what should I do in case of hadoop? I am trying to generate the OpneCL code for a hadoop program that I am running this way:
hadoop jar .java
I have tried adding -Dcom.amd.aparapi.enableShowGeneratedOpenCL=true before and after jar word, both did not work. Here is what I got.
Exception in thread "main" java.io.IOException: Error opening job jar: -Dcom.amd.aparapi.enableShowGeneratedOpenCL=true
at org.apache.hadoop.util.RunJar.main(RunJar.java:90)

Just add the property to the command line which you use to start java.
Specifically somewhere you have a command line like this
java -classpath yourpackage.YourApp
Just add the property like this
java -Dcom.amd.aparapi.enableShowGeneratedOpenCL=true -classpath yourpackage.YourApp

java.io.FileNotFoundException: ~/play-2.1.1/framework/sbt/boot/update.log (No such file or directory)

I wrote a Puppet to install Play 2.1.1 on Virtual Machine running CentOS 6.2.
The Puppet executed the following two commands:
/usr/bin/wget http://downloads.typesafe.com/play/2.1.1/play-2.1.1.zip
/usr/bin/unzip play-2.1.1.zip
When I run play command inside the package, it shows the following error message:

Error during sbt execution: java.io.FileNotFoundException: ~/play-2.1.1/framework/sbt/boot/update.log (No such file or directory)
I didn't change a single line of code in the play-2.1.1 directory. I googled around for the error message, but did not find any useful answer. Could anyone point out what is the problem?

If the file does not exist and cannot be created,FileOutputStream will raise a FileNotFoundException (yes, this seems weird, but see the javadoc).
This error probably means that the user that started play does not have the proper permissions to create ~/play-2.1.1/framework/sbt/boot/update.log or its parent directories.
