Project works in debugger, not after compiling

Hi people,

I'm working on a project that i got from the internet and which I need to modify to my needs.
The project contains 2 jar files that need to be set in the libraries.
The project works fine in the netbeans debugger, but when I compile it it returns the following error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: be.belgium.eid.eidlib
JNI.new_BEID_ID_Data()J
at be.belgium.eid.eidlibJNI.new_BEID_ID_Data(Native Method)
at be.belgium.eid.BEID_ID_Data.(BEID_ID_Data.java:141 )
at eid.Main.main(Main.java:20)

The 2 jar files are copied into a lib subdirectory.

Apparently something is wrong with the libraries, but I can't seem to figure out what. I found some dll's in the windows system32 directory that are likely to be used by the program. I copied them both to the jar file's folder and the lib subdirectory, but no luck there

Googling thought me that i need to set the java_library_path but I'm not sure how to do this in netbeans.

---

java -jar "eid.jar" -Djava.library.path="lib"

did not help either

Can anyone point me in the right direction?

Can you tel me the exact folder structure of dist folder. If you are working on NetBeans there is a folder name dist inside the working folder.

hi,

projectfolder
\_build
\_dist
---\_lib
\_nbproject
\_src
\_test

nothing else

Ok, inside lib you should have all libraries refer in your project. And also main executable jar file should be inside the dist and outside of the lib. Is that right?

this seems to be the case, however, in the meantime i have found that the jar files in the lib use dll's that are in the windows system32 directory.
I tried copying these files in the lib and in the dist folder.
I tried loading them into the program by using in the source code the line:

Code:

---

System.loadLibrary("my.dll");

---

Nothing works...

Very strange since things just work inside netbeans...

Probably you should specify a class path when you try to run?

Can you find manifest file of your project. Check there from where those dll files are linked. Normally those details are included in manifest file.

still no luck with this

manifest file:
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.7.0
Created-By: 10.0-b19 (Sun Microsystems Inc.)
Main-Class: eidlibtest.Eid
Class-Path: lib/beidlib.jar lib/eidlib.jar
X-COMMENT: Main-Class will be added automatically by build

nothing there about the dll's

System.getProperty returns the windows/system32 directory where the dll's are located.

Actually this is in the code:

Code:

---

  static
  {
    try
    {
        System.loadLibrary("beidlibjni");
    }
    catch (UnsatisfiedLinkError e)
    {
      System.err.println("Native code library eidlib failed to load.\n" + e);
      System.exit(1);
    }
  }

---

I don't get the catch message (if I change the name of the dll that is to be loaded, I do), so I'm guessing this is not the problem.
However, further on in the code when a function of the dll is actually called, I get the error
man, this is bugging me!

okay, update: it just works on another PC!
no idea why, anyone any thoughts?
can't seem to find a difference in the system.getProperties();

Ok, if on one system it's working, are you sure that on the previous system has that dll in correct place.

yes, I checked everything.
In fact the dll's are copied when installing another application

It is very strange: as I said: the loadlibrary does not generate an error
I even tried to put in a not existing dll to see if it would go to the catch statement, and it does

Can't you try it without a static block?
