[FIXED] Cannot use JIntellitype with double-clickable jar

[DJGummikuh]

Works like a Charme.
Your code is really MUCH! cleaner... My code was written during my bus trip to work.
I also noticed you removed the dependency on commons-logging. Cool, makes my program a little smaller
Thank you very much for your great support for your library

Awesome! Thanks for testing!

Also I fixed your name on the Contributor's page.

Hi,

Thank you for your tip but the dll still can't be found in my JAR file

Here is my main tree :

|_ lib
|_ jintellitype-1.3.2.jar
|_ myJar.jar
|_ JIntellitype.dll

and my Jar tree :
|_ client.logic.myMain.class
|_ JIntellitype.dll

(I've put the dll in both path to have more chances to detect it)

And in my "myMain.class", I try to load locate the dll like this :

Code: Select all

      // Hook to get the correct path to the dll when we use the JAR
      URL dll = getClass().getResource("/JIntellitype.dll");

           JIntellitype.setLibraryLocation(dll.toString());


Could you help me to find the way to make it works?

Thank you very much !!!

PS: Sorry for my English, I'm French...

Can you try using getFile() instead of toString()?

Code: Select all

dll.getFile()

I am not sure if this is going to be possible with the DLL living inside the JAR as I have never tried it but basically since the System.load wants a file path.

I've tried but it still doesn't works

I don't need the dll to be in the JAR. Be in the same folder would be perfect.

if it is in the same folder as the other code then you should be able to just remove the setLibraryLocation() line. It should just find the Jintellitpye.dll if it is in the same directory as you are executing the code in. If that doesn't work first try hardcoding setLibraryLocation("C:\location\Jintellitype.dll"); just to get past your issues first. Once you have it working then it's just a matter of figuring out how and where to load it in your code.

Thanks for your help

I've tried the first method you propose but I got the same error.

But by hardcoding the fullpath, it succeed !!

So my problem is now to know how to refer to the dll from my main class (which is in the JAR).

Any idea?

What happens in your code if you do...

Code: Select all

File file = new File(".");
System.Out.PrintLn(file.getAbsolutePath());

I am hoping that returns you the directory of where your JAR is so then you could just append "JINtellitype.dll" on the end of it and pass it to SetLibraryLocation().

Bad news...

This out in console: "C:\Users\Pierre\."

[Melloware]

try this one... where MyClass is your Class.

Code: Select all

File file= new File(MyClass.class.getProtectionDomain().getCodeSource().getLocation().toURI().getPath());
System.Out.PrintLn(file.getAbsolutePath());


[Dark$hadow]

Better news!!!

I get now a full path: "C:\Users\Pierre\Desktop\Client\Click2Dial-Computer\build\install\lib\Clic2Dial.jar"

Does the same function without the file name exists?

Many thanks for your help !!!

OK now with that File object you can just call file.getParent().getAbsolutePath() since Parent will be the directory path of CLic2Dial.

Arf nearly !!!

That's the code:

Code: Select all

      File file = null;
      try {
         file = new File(MyClass.class.getProtectionDomain().getCodeSource().getLocation().toURI().getPath());
      } catch (URISyntaxException e1) {
         e1.printStackTrace();
      }
      System.out.println(file.getParent().getAbsolutePath());


I can't call the getAbsolutePath() method ("The method getAbsolutePath() is undefined for the type String")

The solution is near

[Melloware]

Sorry try .getParentFile() or new File(file.getParent()). I know there is a way to get the parent file object.

[Dark$hadow]

Wonderful!!!

The final code is:

Code: Select all

      File file = null;
      try {
         file = new File(MyClass.class.getProtectionDomain().getCodeSource().getLocation().toURI().getPath());
         
      } catch (URISyntaxException e1) {
         // TODO Auto-generated catch block
         e1.printStackTrace();
      }

JIntellitype.setLibraryLocation(file.getParentFile().getAbsolutePath() + "\\JIntellitype.dll");


It's very complicated to find a path

Many tanks to you !!!
