How to set the java.library.path from Eclipse

Question

Don't mess with the library path! Eclipse builds it itself!

Instead, go into the library settings for your projects and, for each jar/etc that requires a native library, expand it in the Libraries tab. In the tree view there, each library has items for source/javadoc and native library locations.

Specifically: select Project, right click -> Properties / Java Build Path / Libraries tab, select a .jar, expand it, select Native library location, click Edit, folder chooser dialog will appear)

Messing with the library path on the command line should be your last ditch effort, because you might break something that is already properly set by eclipse.

If you are adding it as a VM argument, make sure you prefix it with -D:

-Djava.library.path=blahblahblah...

Except the way described in the approved answer, there's another way if you have single native libs in your project.

• in Project properties->Java Build Path->Tab "Source" there's a list of your source-folders
• For each entry, there's "Native library locations", which also supports paths within the workspace.
• This will make Eclipse add it to your java.library.path.

For a given application launch, you can do it as jim says.

If you want to set it for the entire workspace, you can also set it under

Window->
  Preferences->
    Java->
      Installed JREs

Each JRE has a "Default VM arguments" (which I believe are completely ignored if any VM args are set for a run configuration.)

You could even set up different JRE/JDKs with different parameters and have some projects use one, other projects use another.

You can simply add -Djava.library.path=yourPath to the eclipse.ini.

Just add the *.dll files to your c:/windows

You can get the java.library.path from the follow codes:and then add you dll files under any path of you get

import java.util.logging.Logger;

public class Test {


    static Logger logger = Logger.getLogger(Test.class.getName());
    public static void main(String[] args) {
    logger.info(System.getProperty("java.library.path"));
    }
}
