java.lang.UnsatisfiedLinkError: no bridge2java in java.library.path

Can anyone write me how to deal with this error? I am running a project with eclipse (from 2012-2014) configured for Windows. I do it on a Mac but Parallels whit windows 11
What library to use and how to add it, if something else needs to be done ?

Exception in thread "main" java.lang.UnsatisfiedLinkError: no openalprjni in java.library.path

I'm trying to use Java bindings for the project https://github.com/openalpr/openalpr
When I try to launch the java application i got this exception
Exception in thread "main" java.lang.UnsatisfiedLinkError: no openalprjni in java.library.path
I try to load the library in this way:
System.loadLibrary("openalprjni");
The file named libopenalprjni.so it's in this dir
/Users/mario/Sviluppo/openalpr/src/bindings/java
so i'm trying, with eclipse, to load it with this configuration as a VM argument
-Djava.library.path=/Users/mario/Sviluppo/openalpr/src/bindings/java/ but nothing happens
What i'm doing wrong?

Include the openalpr.dll and the required all other dll files from the binaries to your JRE or JDK bin directory. Then try to compile and run your program.
Worked for me.

for me worked:
System.load("/usr/lib/libopenalprjni.so");

JNI error of SCIP

I got scip optsuite from http://scip.zib.de/#scipoptsuite .
It works fine as a standalone program and with the python interface, but I faced the following JNI error when I ran the example.

I would be happy if you could give me a suggestion.
Accordiong to mueldgog's advice, I changed the extension to jnilib. Then another error occurred:
Exception in thread "main" java.lang.UnsatisfiedLinkError: /.../scipoptsuite-3.2.0/scip-3.2.0/interfaces/jni/lib/libjscip-0.1.darwin.x86_64.gnu.opt.spx.jnilib: dlopen(/.../scipoptsuite-3.2.0/scip-3.2.0/interfaces/jni/lib/libjscip-0.1.darwin.x86_64.gnu.opt.spx.jnilib, 1): Library not loaded: lib/liblpispx-3.2.0.darwin.x86_64.gnu.opt.so

otools says:
Load command 11
cmd LC_LOAD_DYLIB
cmdsize 72
name lib/liblpispx-3.2.0.darwin.x86_64.gnu.opt.so (offset 24)
In a Linux environment, where I successfully run the same command, lld says
liblpispx.linux.x86_64.gnu.opt.so => /.../scipoptsuite-3.2.0/scip-3.2.0/lib/liblpispx.linux.x86_64.gnu.opt.so (0x00002b66b3d35000)
So I think I should fix the reference to the absolute path on OS X, but don't know how to fix it.
Could you give any advice for this?

How to connect JPL with SWI-Prolog in Mac OS X

Hi i have a problem with a jpl interface. I want connect JPL with swi-prolog installed with mac-ports with eclipse. I have a jpl.jar and i have tried to import the jar file in eclipse with build path but i have this error: "no jpl in java.library.path".
So i have copied libjpl.dylib in a /opt/local/lib/swipl-7.1.29/bin/ and when i execute the code i have this error: "Exception in thread "main" java.lang.UnsatisfiedLinkError: /opt/local/lib/swipl-7.1.29/bin/libjpl.dylib: dlopen(/opt/local/lib/swipl-7.1.29/bin/libjpl.dylib, 1): Library not loaded: /Users/janw/stable/lib/swipl/lib/x86_64-darwin13.0.0/libswipl.dylib
Referenced from: /opt/local/lib/swipl-7.1.29/bin/libjpl.dylib
Reason: image not found"

After a anoying waste of time i found the solution about that problem.
First of all, its completely necesary to install swi-prolog via macports, if not, as i did, when you point in the
Djava.library.path=/users/rivax/Applications/SWI-Prolog.app/Contents/swipl/lib/x86_64-darwin13.0.0
this exception will apear

So follow these steps.
port install swi-prolog on terminal , if you dont have install already macports command not found will apear so go to https://www.macports.org/install.php and install macports.
navigate to the path of swi prolog macports installation which mine is
/opt/local/lib/swipl-6.6.6/lib/x86_64-darwin14.0.0
copy this path and set in java.library.path in the java VM as -Djava.library.path=/opt/local/lib/swipl-6.6.6/lib/x86_64-darwin14.0.0
Now .pl with jpl.jar will be able to execute and the consults will run.
Hope it will help you and every person who find this hell problem.
Cheers frank.

How can i solve this problem?

Check your OS that whether it is 32bit or 64bit.Then install the appropriate version opencv and javacv.
