giving 'java.library.path' in netbeans for .dll/.so files

Question

How do i give the path for the .dll or .so file in netbeans to load the library using

System.loadLibrary("Foo")

I read this on netbeans page but couldn't help me. as it gives the unsatisfied link error.

These are the two things i tried :

In the following snapshot i created a lib folder inside the netbeans project and placed the dll files inside it.

In the second snapshot i created a lib folder inside the modules folder and placed all the dll files inside lib folder as stated in the link .

But both of them give me unsatisfied link error exception. How do i set java.library.path in netbeans so that i can directly test the application from netbeans, without having to go and write on the terminal ?

Answer 1

Its working now. Some little bit setting you have to do with your Netbean IDE.Only of Netbean IDE.

Follow the Steps :-

==>Right click on the Project
==>Properties
==>Click on RUN
==>VM Options : -Djava.library.path="C:\Your Directory where Dll is present"
==>Ok

Its working 100%. I have done this in my own project.

I'm using Mac OS X Yosemite and Netbeans 8.02, I got the same error and the simple solution I have found is like above, this is useful when you need to include native library in the project. So do the next for Netbeans:

1.- Right click on the Project
2.- Properties
3.- Click on RUN
4.- VM Options: java -Djava.library.path="your_path"
5.- for example in my case: java -Djava.library.path=</Users/Lexynux/NetBeansProjects/NAO/libs>
6.- Ok

I hope it could be useful for someone. The link where I found the solution is here: java.library.path – What is it and how to use

IF you are working on "NetBeans Modules"

DLLs or SOs can be placed in the folder release/modules/lib/ in a module project's sources (look in the Files tab). This will make them appear in the final NBM or application in a lib subdirectory beneath where the module's JAR resides. Then just use System.loadLibrary as usual.

To me JDeveloper's suggestion didn't work. However, the method that I came across this early afternoon works handy. It is for netbeans 8.02, and Visual Studio 2013 generated dll.

1. create a package(eg, "dll") under [Source Packages] node of netbeans project
2. put/copy a dll file(eg, simpleDLL.dll) into the package(eg, "dll")
3. on the [Libraries] node of the netbeans project, right-click and choose "Add Jar/Folder...",
4. navigate to the folder("src") that contains the folder("dll") for the package that you created in step 1 above (it could be "...\\src\\dll" in my example), select package folder("dll") and click [Open] button to select it.

-- now you should have added a folder("dll") (which contains the dll file{simpleDLL.dll}) to the Libraries node of the project.

That's it. It should work! Good luck.
